Sherritt Nickel-Cobalt Refinery Shutdown Exposes Cuba Feedstock Risk

Sherritt

Sherritt nickel cobalt refinery operations at Fort Saskatchewan in Alberta will enter a shutdown state after feedstock from the company’s Moa joint venture in Cuba became unavailable.

Sherritt nickel cobalt refinery production depends on mixed sulfide precipitate shipped from the Moa mine, where nickel and cobalt ore is mined and processed before final refining in Canada.

Sherritt nickel cobalt refinery shutdown highlights the vulnerability of processing facilities that rely on a single international feed source. The company has not provided a timeline for restarting nickel and cobalt refining.

The shutdown follows fuel-related disruptions at Moa and increased US sanctions on Cuba, which led Sherritt to suspend its direct participation in the joint venture.

Cuba Disruption Breaks the Mine-to-Refinery Supply Chain

The Moa joint venture is owned equally by Sherritt and Cuba’s General Nickel Company. Its operating model links Cuban mining and intermediate processing directly with Canadian refining.

Ore from Moa is processed into mixed sulfide precipitate before shipment to Fort Saskatchewan for conversion into finished nickel and cobalt products.

That structure becomes vulnerable when upstream operations stop. Sherritt had already warned that existing refinery feed inventories would last only until around mid-June.

Fuel shortages initially forced the Moa operation to suspend mining activity in February. Additional uncertainty followed after the US expanded sanctions on Cuba, prompting Sherritt to suspend its direct participation in the joint venture in May.

The refinery will remain shut until Moa mining and processing resume and enough intermediate material is available to rebuild feed supply.

This shows that refining capacity alone does not guarantee critical mineral security. A plant can remain technically capable of producing metal while geopolitical or logistical problems interrupt the upstream feed required to operate it.

Nickel and Cobalt Output Stops While Byproduct Production Continues

Sherritt will use the shutdown period to carry out maintenance at Fort Saskatchewan.

The company will continue producing fertilizer and sulfuric acid, showing that some parts of the industrial complex can remain operational even while nickel and cobalt refining is suspended.

However, the loss of finished nickel and cobalt output reduces North American availability of two important materials used across stainless steel, superalloys, batteries and other industrial applications.

Cobalt is particularly relevant to aerospace, defence and battery supply chains, while refined nickel remains important for both conventional metallurgy and selected battery chemistries.

The disruption also underlines the strategic importance of diversified feedstock. Refiners that can process material from multiple mines or jurisdictions have greater resilience when one supply route fails.

For Sherritt, the key issue is therefore not refinery maintenance but restoration of a stable Cuban feed stream.

The Metalnomist Commentary

Fort Saskatchewan shows that midstream capacity is only as secure as its upstream feed. North American critical minerals policy must address concentrate and intermediate supply alongside domestic refining capacity.

JetZero Z4 Aircraft Plant Breaks Ground in North Carolina

JetZero

JetZero Z4 aircraft production has moved a step closer to commercial scale after the California-based aerospace start-up broke ground on its first manufacturing plant in Greensboro, North Carolina. The company plans to invest $4.7bn in the new facility.

JetZero Z4 aircraft production will take place at an 8mn ft² site designed to manufacture the company’s 250-passenger aircraft. Deliveries are targeted for the early 2030s.

JetZero Z4 aircraft output could eventually reach 20 planes per month by the late 2030s. If achieved, that would establish JetZero as a meaningful new entrant in the global commercial aerospace manufacturing base.

The project is also expected to create more than 14,500 jobs, giving North Carolina another major aerospace manufacturing hub.

Z4 Production Could Add a New Large Aircraft Platform

JetZero is developing the Z4 around a blended wing body configuration designed to improve aerodynamic efficiency compared with conventional tube-and-wing aircraft.

The company is targeting up to 50% better fuel efficiency across a range of about 5,000 nautical miles.

If the aircraft reaches commercial production at planned rates, it would require a substantial new supply chain for structures, engines, landing systems, avionics and precision-machined components.

That creates potential demand across aerospace materials including aluminium, titanium, nickel-based superalloys, advanced composites and specialty steels.

The planned production rate of 20 aircraft per month would also require a supplier network capable of supporting consistent industrial-scale deliveries rather than prototype volumes.

For materials producers and component manufacturers, the critical milestone will therefore be certification and production ramp-up rather than the factory construction itself.

The Greensboro facility gives JetZero a physical base from which to move from aircraft development toward serial manufacturing.

Military Variants Expand Strategic Aerospace Potential

JetZero is also developing military versions of the Z4, including aerial refuelling and transport configurations.

This broadens the programme beyond commercial aviation and could provide another route to production scale if defence customers adopt the platform.

Aerial refuelling and transport aircraft require high structural durability, long range and efficient fuel consumption, making the Z4 concept potentially relevant to future military logistics.

The dual-use strategy could also strengthen the business case for the Greensboro plant by allowing common manufacturing infrastructure to support both civilian and defence programmes.

For the US aerospace supply chain, a successful JetZero ramp-up would create another large aircraft platform alongside established Boeing and defence programmes.

However, the development timeline remains long. JetZero must still progress through testing, certification, supplier qualification and industrialisation before its projected early-2030s deliveries.

The scale of the factory therefore signals ambition, but execution over the next several years will determine whether the Z4 becomes a major new source of aerospace materials demand.

The Metalnomist Commentary

JetZero’s Greensboro project could create an entirely new large-aircraft supply chain if the Z4 reaches commercial scale. For metals and component suppliers, the real opportunity will emerge once certification and production schedules begin translating into qualified long-term material demand.

Lockheed F-35 Labor Contract Secures Fort Worth Production Continuity

F-35

Lockheed F-35 labor contract has been ratified by unionized employees at the company’s Fort Worth, Texas, assembly site, removing the immediate risk of labor disruption at one of the most important US fighter aircraft production facilities.

Lockheed F-35 labor contract will run for five years through June 2031 and includes annual wage increases, additional vacation benefits and a $6,000 ratification bonus. Workers represented by the International Association and Aerospace Workers approved the agreement on 14 June.

Lockheed F-35 labor contract is strategically important for the aerospace materials supply chain because the F-35 is highly titanium intensive. Each aircraft contains an estimated 5,900lb of titanium, equivalent to roughly 20% of total aircraft weight.

The agreement therefore provides greater production certainty not only for Lockheed Martin, but also for titanium mills, forgers, machinists and component suppliers tied to the F-35 programme.

Labor Stability Protects F-35 Production Schedules

The previous labor agreement was due to expire at midnight on 14 June, creating the possibility of disruption if negotiations failed.

Lockheed and the union reached a tentative agreement on 11 June before workers formally ratified the contract three days later.

The agreement also covers employees at Edwards Air Force Base in California and Patuxent River Naval Air Station in Maryland, extending labor stability beyond the Fort Worth assembly operation.

For Lockheed, avoiding a work stoppage is particularly important because fighter aircraft production depends on highly specialised labour and tightly coordinated supplier schedules.

A prolonged disruption at final assembly could quickly affect upstream suppliers because aerospace components are produced according to programme-specific delivery schedules and qualification requirements.

The five-year agreement gives Lockheed greater visibility over workforce costs and production continuity through the end of the decade.

Titanium Supply Chain Benefits From Production Continuity

The F-35 remains one of the most titanium-intensive major aircraft programmes. Titanium is used extensively because of its high strength-to-weight ratio, corrosion resistance and compatibility with composite structures.

At around 5,900lb of titanium per aircraft, changes in F-35 production volumes can have a meaningful impact on aerospace-grade titanium demand.

The material requirement extends beyond sponge and ingot. F-35 production supports demand for titanium plate, billet, forgings, castings, machined components and scrap recycling across a highly qualified supply chain.

Labor stability at Fort Worth therefore reduces one potential source of demand volatility for titanium suppliers.

The effect also extends to other aerospace materials, including nickel-based superalloys, aluminium and specialty steels used across engines, structures and landing systems.

For suppliers, predictable aircraft production is especially valuable because aerospace capacity cannot be adjusted quickly. Qualification requirements, long lead times and specialised equipment make sudden production changes difficult to absorb.

The Metalnomist Commentary

The labor agreement removes a near-term operational risk from one of the world’s most titanium-intensive defense programmes. For the titanium supply chain, stable F-35 production provides valuable demand visibility through a period of rising defense manufacturing requirements.

Norsk Titanium RPD Technology Targets US Submarine Applications

Norsk Titanium

Norsk Titanium RPD technology is moving deeper into US defense applications after the company secured a $4.2mn contract to develop rapid plasma deposition for maritime and submarine use.

Norsk Titanium RPD technology will be developed over an 18-month period under the Defense Industrial Base Expansion, Development, and Growth Enterprise initiative. The work will focus on qualifying additive-manufactured products for highly critical naval applications.

Norsk Titanium RPD technology is already established around titanium alloys, but the new programme will also expand the process into nickel-based alloys. That broadens the potential market from corrosion-resistant structural components into higher-temperature and more demanding applications.

The programme is strategically important because submarine supply chains require highly qualified materials, long service lives and strict control over metallurgy and manufacturing consistency.

Titanium Additive Manufacturing Fits Maritime Corrosion Requirements

Titanium is especially valuable in marine environments because of its strong corrosion resistance in seawater.

Commercially pure titanium and alloys such as Grade 5 and Grade 7 can provide long-term durability where conventional steels would require greater corrosion protection or maintenance.

This makes titanium attractive for submarine and maritime components exposed to saltwater, pressure and difficult operating conditions.

Additive manufacturing can add another advantage. Near-net-shape production can reduce the amount of expensive titanium that must be machined away from forged or wrought stock.

That can improve material utilisation and shorten lead times for complex components, particularly where conventional manufacturing requires large forgings or extensive machining.

For defense programmes, reducing dependence on long-lead forgings can be strategically valuable. Qualified additive processes could provide an alternative route for components where supply capacity is constrained.

However, qualification remains the critical barrier. Submarine components operate in safety-critical environments, so mechanical properties, fatigue behaviour, defect control and repeatability must be demonstrated before widespread adoption.

Nickel Alloys Could Expand RPD Beyond Structural Titanium

The move into nickel-based alloys could significantly broaden Norsk Titanium's addressable market.

Nickel superalloys are widely used where components must retain strength, corrosion resistance and thermal stability under demanding conditions.

For naval applications, this could create opportunities in propulsion, high-temperature systems and specialised mechanical components alongside titanium structures.

The combination of titanium and nickel alloy capability would also strengthen Norsk Titanium's position as a broader defense manufacturing supplier rather than a single-material additive producer.

The US defense industrial base is increasingly focused on manufacturing resilience, particularly for components dependent on limited forging, casting or machining capacity.

RPD technology could support that objective if it can reduce lead times while meeting military qualification standards.

The longer-term significance therefore lies in process substitution. Norsk is not simply selling additive manufacturing equipment; it is trying to qualify a new production route for materials and components traditionally supplied through conventional metallurgical processes.

The Metalnomist Commentary

Norsk Titanium's submarine programme shows that additive manufacturing is moving into increasingly critical defense applications. If RPD qualifies successfully in both titanium and nickel alloys, the technology could reduce dependence on long-lead forgings and expand flexibility across the naval supply chain.

Pursuit Aerospace Acquisition Expands Titanium and Inconel Machining Capacity

Leesta Industries

Pursuit Aerospace acquisition of Leesta Industries expands the US aircraft component manufacturer's machining capabilities while strengthening its existing forging operations. The deal also gives Pursuit its first facility in Montreal, one of North America's major aerospace manufacturing hubs.

Pursuit Aerospace acquisition adds Leesta's 38,000ft² facility in Pointe-Claire, Quebec, where the company operates milling, lathe and mill-turn equipment for precision aerospace parts.

Pursuit Aerospace acquisition also expands its exposure to several Pratt & Whitney engine platforms. The combination of forging and machining gives Pursuit greater control over more stages of aerospace component production.

Leesta manufactures engine and landing gear components including bearing housings and actuator assemblies from titanium, stainless steel and Inconel. Financial terms of the transaction were not disclosed.

Titanium and Inconel Machining Strengthens Engine Supply Capability

Leesta's expertise in difficult-to-machine aerospace materials adds strategic value to Pursuit's manufacturing platform. Titanium and nickel-based superalloys require specialised tooling, process control and technical experience.

Titanium combines high strength with relatively low weight and strong corrosion resistance, making it important for aircraft engines, structural parts and landing systems.

Inconel and other nickel-based alloys provide strength and oxidation resistance at high temperatures. These characteristics make them essential for engine components operating under extreme thermal and mechanical loads.

Machining these materials can become a bottleneck even when raw metal is available. Tool wear, heat generation and strict dimensional requirements make aerospace machining significantly more complex than conventional industrial production.

By adding Leesta's capabilities, Pursuit can integrate more machining work with its forging operations and reduce dependence on external subcontractors.

Montreal Acquisition Deepens Pratt & Whitney Supply Chain Position

The Montreal location gives Pursuit access to a dense aerospace manufacturing ecosystem with established engineering talent, suppliers and major aircraft and engine programmes.

Leesta's existing work on Pratt & Whitney platforms strengthens Pursuit's relationship with one of the world's major aircraft engine manufacturers.

This matters because aerospace supply chains rely heavily on qualified suppliers. Once a machining process, component and material route are approved for an engine programme, replacing the supplier can require extensive testing and certification.

The acquisition therefore increases both production capacity and customer relevance. It also positions Pursuit to capture more value from each component by combining forging, machining and finishing capabilities.

For metals suppliers, the transaction reinforces strong demand for qualified titanium and nickel alloy processing. Growth in commercial and defence aerospace requires not only additional raw material, but also sufficient downstream capacity to convert it into flight-ready parts.

The Metalnomist Commentary

Aerospace bottlenecks increasingly sit in qualified machining rather than raw metal availability alone. Pursuit's acquisition strengthens its ability to turn titanium and Inconel into higher-value engine and landing gear components within a major aerospace cluster.

RTC Aerospace Acquisition Expands US Titanium and Superalloy Machining Capacity

RTC Aerospace

RTC Aerospace acquisition of Automatic Products expands the US manufacturer’s machining capacity for complex aerospace and defence components. The deal adds a fifth production facility and strengthens RTCA’s position in precision manufacturing for high-value aircraft applications.

RTC Aerospace acquisition includes Automatic Products’ 120,000ft² facility in Sumner, Washington. The site adds capabilities across milling, turning, deburring, grinding and honing.

RTC Aerospace acquisition is strategically important because the plant processes high-temperature metals and superalloys including titanium, stainless steel and Inconel. These materials are widely used in aerospace structures, engines and defence systems where machining capability is highly specialised.

Financial terms were not disclosed, but the transaction broadens RTCA’s manufacturing footprint and gives the company more capacity to serve commercial and military aerospace customers.

Titanium and Inconel Machining Add Strategic Capacity

Aerospace machining requires more than conventional metalworking. Titanium and nickel-based superalloys are difficult to process because of their strength, heat resistance and tendency to generate high tool wear.

Automatic Products brings established capability in these materials. That matters as aerospace production rises and manufacturers seek qualified suppliers able to machine complex components at consistent quality.

Titanium remains important for aircraft structures, landing systems and engine-related applications because of its strength-to-weight ratio and corrosion resistance. Inconel and other nickel superalloys are essential for components exposed to high temperatures and mechanical stress.

The Sumner facility therefore adds capacity in precisely the materials where aerospace supply chains can face bottlenecks. Increasing machining capability can help convert more forged, cast or wrought metal into finished aerospace parts.

The acquisition also provides RTCA with additional production flexibility. Multiple facilities allow manufacturers to distribute workloads, manage customer programmes and reduce dependency on individual sites.

Aerospace Growth Supports Precision Manufacturing Consolidation

The deal reflects broader consolidation across the aerospace supply chain. Aircraft manufacturers and defence contractors increasingly need suppliers with enough scale to support higher production volumes while maintaining strict quality and traceability.

Machining businesses can benefit from this trend because qualified aerospace components often require extensive processing after primary metal production. That gives specialised manufacturers an important role between mills, forgers and final aircraft assemblers.

RTCA’s expanded footprint could also improve its ability to manage larger programmes and more complex assemblies. The addition of grinding, honing and finishing capabilities strengthens the company’s position beyond basic machining.

For metals suppliers, the deal reinforces the importance of downstream processing capacity. More titanium or superalloy production does not automatically translate into aircraft output unless qualified machining capacity is also available.

As commercial and defence aerospace demand grows, companies that control both capacity and specialised process knowledge will have a stronger position in the supply chain.

The Metalnomist Commentary

RTCA’s acquisition shows that aerospace bottlenecks increasingly sit in qualified machining, not only raw metal supply. Titanium and Inconel capacity becomes more valuable when manufacturers can reliably convert those materials into flight-ready components.

Boeing 737 MAX Production Cleared to Rise to 47 Aircraft a Month

Boeing 737 MAX

Boeing 737 MAX production is set to increase after the US Federal Aviation Administration approved a higher build rate of 47 aircraft per month. The move gives Boeing more room to lift narrowbody output after operating at 42 aircraft per month since the end of 2025.

Boeing 737 MAX production could reach the new rate within the next 30-90 days, according to the FAA. That timeline is broadly in line with Boeing’s expectation of reaching 47 aircraft per month during the summer.

Boeing 737 MAX production growth is important for the wider aerospace supply chain because higher build rates translate into stronger demand for aluminium, titanium, nickel superalloys, fasteners, landing gear, engines and precision components.

The increase also marks another step away from the tighter production controls imposed after quality concerns. Boeing is now trying to raise output while maintaining stricter oversight across manufacturing and supplier operations.

Renton and Everett Will Support the Next Production Step

Boeing will increase 737 MAX output from its Renton, Washington, facility. At the same time, the company is preparing a new final assembly line in Everett, Washington.

The Everett line is expected to start later this year and will support future increases beyond 47 aircraft per month. This gives Boeing additional assembly capacity as it works through its large commercial backlog.

Future production increases will be more gradual. Boeing has said build rates will rise in increments of five aircraft per month, with at least six months between each step.

That approach reflects the company’s focus on quality control and manufacturing stability. Faster production is valuable only if suppliers, inspections and final assembly can support the higher rate without new disruptions.

The current 42 aircraft per month rate was reached after the FAA lifted its previous 38-per-month cap in October. The latest approval therefore represents another measured step in Boeing’s recovery.

Higher Build Rates Lift Aerospace Materials Demand

A production increase from 42 to 47 aircraft per month means five additional narrowbody aircraft entering the manufacturing system every month. That has a direct impact on upstream materials and component suppliers.

Commercial aircraft rely heavily on aerospace-grade aluminium for structures and skins, titanium for high-strength and corrosion-resistant components, and nickel-based superalloys for engines and high-temperature systems.

Higher output also supports demand for forgings, castings, fasteners, composites and specialty machined parts. Many of these products come from tightly qualified supply chains with limited supplier flexibility.

The Everett expansion could amplify that demand further if Boeing receives approval for additional rate increases. Each production step places more pressure on suppliers to expand capacity while preserving aerospace quality standards.

This is especially relevant for titanium and nickel alloy suppliers. Aerospace demand is often less price-sensitive than industrial demand because material qualification and supply continuity are more important than spot cost.

For the metals market, Boeing’s production recovery therefore matters beyond aircraft deliveries. It can strengthen demand across the aerospace materials chain and improve visibility for suppliers with qualified positions on the 737 MAX programme.

The Metalnomist Commentary

Boeing’s latest production approval is a positive signal for aerospace materials demand, but the real constraint is supplier readiness. The next phase of 737 MAX growth will depend on whether qualified aluminium, titanium, superalloy and component suppliers can scale with Boeing.

Aircraft Engine MRO Bottlenecks Set to Lift Aerospace Superalloy Demand

IATA

Aircraft engine MRO bottlenecks are becoming a structural constraint for global aviation as durability problems, rapid fleet growth and limited spare parts increase maintenance demand. The International Air Transport Association says the industry must expand parts availability and repair capacity to protect long-term fleet resilience.

Aircraft engine MRO bottlenecks are particularly acute for Pratt & Whitney geared turbofan engines and CFM International LEAP engines. Premature component failures are shortening time on wing and forcing additional shop visits alongside scheduled maintenance.

Aircraft engine MRO bottlenecks also carry significant implications for specialty metals. Rising overhaul activity will increase consumption of nickel and cobalt superalloys, refractory metals and titanium used in high-pressure turbine, compressor and structural engine components.

The pressure is unlikely to disappear quickly. In-service LEAP and GTF fleets are expected to expand five- to sixfold between 2024 and 2040 as airlines replace older narrowbody aircraft with newer platforms.

Durability Problems Accelerate Engine Shop Visits

Pratt & Whitney’s powdered metal issue has been one of the largest recent disruptions. The problem affects high-pressure turbine and compressor disks in GTF engines and has required affected aircraft to undergo additional shop visits for component replacement.

Groundings of GTF-powered aircraft peaked at 648 units in March 2025, equal to 28% of the fleet. These aircraft remained unavailable while operators waited for maintenance slots and replacement parts.

CFM’s LEAP engines have faced separate durability challenges. Stage-1 high-pressure turbine blades have shown premature wear, particularly in hot and harsh operating environments.

These problems reduce engine time on wing. Airlines must therefore send engines to maintenance facilities earlier than planned, adding unscheduled work to an already growing base of routine overhauls.

The scale will increase significantly as newer engines dominate the global narrowbody fleet. Annual LEAP shop visits are expected to exceed 5,000 by 2040, while GTF shop visits could surpass 2,000.

Engine manufacturers are adding MRO capacity directly and through partners. However, new repair shops alone cannot solve the problem if replacement parts, forgings and qualified components remain constrained.

MRO Growth Strengthens Nickel, Cobalt and Titanium Demand

High-pressure engine components operate at extreme temperatures and mechanical loads. This makes nickel-based superalloys essential for turbine disks, blades and other hot-section components.

Cobalt and refractory elements also play important roles in advanced superalloy systems. Their ability to maintain strength and oxidation resistance under extreme conditions makes substitution difficult in many engine applications.

Titanium demand will also benefit from higher maintenance activity. Titanium alloys are widely used in compressor sections, fan systems and structural engine components because of their strength-to-weight ratio and corrosion resistance.

Limited-life high-pressure parts on mature engines typically require replacement after around 15,000-20,000 cycles. On a single-aisle aircraft, that can correspond to roughly five to seven years of operation.

The growing LEAP and GTF installed base therefore creates a predictable long-term materials cycle. Even if durability problems improve, fleet growth alone will generate substantially more engine overhaul demand.

The supply-chain challenge extends beyond raw metals. Engine makers need qualified forgings, castings, powder products, machined parts, heat treatment and nondestructive testing capacity.

For specialty metals suppliers, MRO demand can be particularly attractive because replacement parts require certified material and tightly controlled processing routes. Aerospace qualification barriers also limit how quickly new competitors can enter.

IATA is calling for better access to spare parts, stronger long-term supply agreements and industry-wide operating standards. Without those changes, maintenance capacity may continue to lag fleet growth.

The Metalnomist Commentary

Engine MRO is becoming one of the strongest long-term demand channels for aerospace superalloys and titanium. The real bottleneck will increasingly be qualified parts and processing capacity rather than raw metal availability alone.

Airbus Safran Aubert & Duval Deal Deepens Control of Aerospace Speciality Metals

Aubert & Duval

Airbus Safran Aubert & Duval ownership is set to consolidate further after the two European aerospace groups agreed to acquire Tikehau Capital’s stake in the French speciality metals producer.

Airbus Safran Aubert & Duval control is strategically important because the company manufactures bars, forgings, ingots and other products from speciality steels, nickel-based superalloys and titanium. These materials are critical for aircraft engines, structural components and defence applications.

Airbus Safran Aubert & Duval ownership will be split more directly between the two industrial buyers after Tikehau’s stake is divided equally between them. The transaction remains subject to regulatory approvals.

The deal strengthens vertical control over a strategic European aerospace materials supplier at a time when aircraft manufacturers continue to face bottlenecks in forgings, superalloys and titanium components.

Aerospace Groups Secure Critical Forging and Alloy Capacity

Aubert & Duval occupies an important position between raw metal production and finished aerospace components. Its products include speciality alloy ingots, bars and forgings used in demanding high-temperature and high-strength applications.

This makes the company strategically relevant to both Airbus and Safran. Airbus needs qualified titanium, steel and superalloy products across aircraft structures and systems, while Safran depends heavily on high-performance metals for jet engine components.

Forging capacity is particularly important. Aerospace forgings require specialised equipment, long qualification cycles and tight process control, making it difficult to replace suppliers quickly when capacity tightens.

Superalloys also remain essential for hot-section engine components because they retain mechanical strength and corrosion resistance at extreme temperatures.

Titanium serves a different but equally important role. Its strength-to-weight ratio and corrosion resistance make it valuable in aircraft structures, landing gear, engine systems and other high-performance applications.

By increasing direct ownership, Airbus and Safran gain stronger influence over investment, capacity planning and production priorities at a supplier embedded deep inside their supply chains.

European Supply Security Drives Vertical Integration

Airbus, Safran and Tikehau originally acquired Aubert & Duval from Eramet in April 2023. The latest transaction moves the company even closer to its two largest strategic industrial stakeholders.

The French government also retains a special share to protect national strategic interests. That structure highlights the importance of Aubert & Duval not only to commercial aviation but also to defence and sovereign industrial capability.

The transaction reflects a wider aerospace trend toward securing critical suppliers rather than relying entirely on open-market procurement. Aircraft backlogs remain high, while qualified metals capacity has struggled to expand quickly enough in several segments.

Direct ownership can help protect investment in furnaces, forging presses, heat treatment and downstream processing. It can also improve coordination between material availability and aircraft or engine production schedules.

For Europe, this matters because aerospace supply security increasingly depends on retaining domestic capability in specialty alloys and high-value metal processing.

The transaction therefore goes beyond a financial restructuring. It strengthens Airbus and Safran’s control over one of Europe’s most strategically important producers of titanium, speciality steels and superalloys.

The Metalnomist Commentary

Airbus and Safran are treating speciality metals capacity as strategic infrastructure rather than a conventional supplier relationship. In aerospace, control over qualified titanium, superalloy and forging capacity is becoming as important as aircraft assembly itself.

ATI Aerospace Machining Expansion Targets Jet Engine Supply Bottlenecks

ATI Alloys

ATI aerospace machining expansion has moved downstream with a new 200,000ft² facility in Chihuahua, Mexico, focused on machining, inspection and qualification of critical jet engine components. The site has been operational since April and marks ATI’s first manufacturing location in Mexico.

ATI aerospace machining expansion strengthens the US specialty alloys producer’s position beyond raw material and forging supply. Nearly half of the new plant is dedicated to machining forged components used in high-pressure engine sections, where nickel-based superalloys are essential because of extreme heat and mechanical loads.

ATI aerospace machining expansion also addresses a persistent aerospace constraint: qualified downstream capacity. Strong demand for new engines and spare parts has increased pressure not only on alloy and forging supply, but also on machining, nondestructive testing and final quality verification.

The Chihuahua location gives ATI access to an established aerospace manufacturing cluster, trained workers and nearby suppliers. Customer qualification is already under way for components serving both existing and next-generation engine platforms.

Nickel Superalloy Machining Becomes a Critical Engine Bottleneck

High-pressure sections of jet engines operate under some of the most demanding conditions in industrial manufacturing. Components must withstand high temperatures, rotational stress, fatigue and repeated thermal cycling.

Nickel-based superalloys are therefore widely used in these engine sections because they retain strength and oxidation resistance at elevated temperatures. But producing the alloy is only one part of the supply chain.

Forged engine components require extensive precision machining before installation. Nickel superalloys are difficult to machine because of their high strength, work hardening and heat resistance, which increase tool wear and processing time.

That makes qualified machining capacity strategically important. Aerospace manufacturers cannot simply move parts to an unapproved supplier when capacity becomes tight because every process must meet strict customer and regulatory requirements.

ATI’s new facility therefore extends the company further into value-added processing. Instead of supplying only specialty alloy or forged material, it can provide more finished components closer to engine assembly.

The remainder of the Chihuahua plant is dedicated to inspection, including nondestructive testing and quality verification. These processes are critical because internal cracks, surface defects or dimensional deviations can make high-value engine components unusable.

Customer Qualification Could Deepen ATI’s Aerospace Integration

ATI said engine manufacturers and other customers are working aggressively to qualify the new facility. That suggests customers are actively looking for additional approved capacity to relieve bottlenecks.

The facility will process components for both legacy and next-generation engine models. This gives ATI exposure to two important demand streams: new aircraft production and the aftermarket replacement cycle.

Legacy engines generate recurring demand for spare components as fleets remain in service. At the same time, newer engine platforms require higher-performance materials and increasingly complex manufacturing routes.

This combination supports long-term demand for nickel superalloys, titanium and other specialty aerospace materials. But supply-chain performance increasingly depends on how quickly those materials can move through forging, machining, heat treatment, inspection and qualification.

ATI’s Mexico investment reflects this shift. Aerospace suppliers are moving closer to integrated component production as customers seek fewer bottlenecks between raw material and finished part.

Financial details and production capacity were not disclosed, so the immediate earnings impact remains unclear. But strategically, the site gives ATI a larger role in one of the highest-value sections of the aerospace materials chain.

The Metalnomist Commentary

ATI’s Chihuahua plant shows that aerospace shortages are moving downstream from alloy supply into machining and qualification. In jet engines, the competitive advantage increasingly belongs to suppliers that can control more of the path from superalloy to finished, approved component.

Sherritt Refinery Shutdown Exposes Canada’s Dependence on Cuban Nickel Feed

Sherritt International

Sherritt refinery shutdown plans will halt nickel and cobalt production at the company’s Fort Saskatchewan facility in Alberta after feedstock from Cuba’s Moa joint venture ran out. The move highlights how upstream disruption can strand downstream refining capacity even in a politically secure jurisdiction.

Sherritt refinery shutdown operations will remain in place until mining and processing at Moa can resume and mixed sulfide precipitate shipments to Canada are restored. The company has not given a restart timeline.

Sherritt refinery shutdown is strategically important because Fort Saskatchewan converts Cuban mixed sulfide precipitate into finished nickel and cobalt. The refinery therefore depends on continuity across mining, processing, shipping and sanctions-sensitive trade routes.

Sherritt will use the shutdown period to complete maintenance work. Fertilizer and sulfuric acid production will continue, preserving part of the site’s industrial activity while nickel and cobalt refining is suspended.

Moa Feed Disruption Strands Canadian Refining Capacity

The Fort Saskatchewan refinery relies on the Moa joint venture in Cuba for its nickel and cobalt feed. Ore is mined and processed at Moa into mixed sulfide precipitate before being shipped to Alberta for refining.

That supply chain began to weaken in February when fuel shortages forced the joint venture to suspend mining operations. Feed inventories in Canada subsequently declined, with Sherritt previously expecting available material to last only until mid-June.

The problem then became more complex in May. Sherritt suspended direct participation in the Moa joint venture after the US expanded sanctions on Cuba under the International Emergency Economic Powers Act.

The company has maintained that suspension, leaving the future of Cuban production uncertain. Without fresh MSP shipments, Fort Saskatchewan cannot continue normal nickel and cobalt refining.

This illustrates a critical supply-chain weakness. Refining assets may sit inside Canada, but their security still depends on where upstream feed originates.

For North American critical minerals policy, that distinction matters. Domestic refining capacity does not create supply independence if raw materials remain tied to politically exposed jurisdictions.

Nickel and Cobalt Supply Security Shifts Toward Feedstock Control

Nickel and cobalt remain important to batteries, superalloys, aerospace, industrial chemicals and defence-related manufacturing. Reliable refining capacity is therefore strategically valuable.

But Sherritt’s shutdown shows that feedstock security must be treated as part of refinery security. A plant without dependable concentrate or intermediate supply becomes an idle asset regardless of its technical capability.

The Fort Saskatchewan site still has value because its processing infrastructure and operating expertise remain in place. Maintenance during the shutdown may help preserve restart readiness if Moa supply resumes.

However, the absence of a clear restart timeline increases uncertainty. Sherritt must either restore the Cuban supply chain or eventually secure another viable feed route if the disruption becomes prolonged.

The situation also raises a broader question for western critical minerals strategies. Governments are investing heavily in domestic processing, but those projects need diversified and compliant raw material sources to remain resilient.

Sherritt’s experience shows why mining, intermediate processing and refining must be planned as one integrated supply chain rather than separate assets.

The Metalnomist Commentary

Fort Saskatchewan is a reminder that secure refining capacity is only as strong as its feedstock chain. Canada can host the refinery, but without reliable upstream material, geopolitical risk still determines whether nickel and cobalt actually reach the market.

Brazil Flight Demand Hits New May Record as Domestic and International Traffic Grow

Brazil's flight

Brazil flight demand continued to expand in May, with domestic and international airlines carrying a combined 10.6mn passengers. The result marked Brazil’s fifth monthly passenger record this year and reinforced the strength of one of Latin America’s largest aviation markets.

Brazil flight demand rose across both domestic and international routes. Domestic airlines transported 8.3mn passengers, up 1.9% from May 2025 and the highest May volume in Brazilian aviation history.

Brazil flight demand measured by revenue passenger kilometres also increased by 2.5% year on year, while available seat kilometres rose by 2.8%. The figures show airlines are adding capacity broadly in line with passenger growth.

The trend is relevant beyond airlines. Sustained traffic growth supports aircraft utilisation, fleet expansion, maintenance demand and longer-term consumption of aerospace materials including aluminium, titanium and nickel-based alloys.

Domestic Traffic Supports Fleet and Maintenance Demand

Latam’s Brazilian subsidiary carried 3.3mn domestic passengers in May, up 5.3% from a year earlier. Its domestic market share increased to almost 40% from 38.5% in May 2025.

Gol held 31.5% of the domestic market, up from 30.4%, while Azul’s share declined to 28.7% from 31%. This shift shows that passenger growth is also reshaping competition among Brazil’s leading carriers.

Rising passenger volumes increase aircraft utilisation, which supports demand for maintenance, repair and overhaul services. Higher utilisation also accelerates component replacement cycles across engines, landing gear, structures and cabin systems.

For aerospace materials suppliers, this matters because growing flight activity supports recurring demand beyond new aircraft production. Titanium, aluminium, specialty steels and nickel superalloys are consumed through both original equipment manufacturing and aftermarket maintenance.

Brazil also has strategic significance because of Embraer’s domestic manufacturing base. Strong local aviation demand can support a broader aerospace ecosystem across aircraft production, components, maintenance and engineering services.

International Growth Adds to Brazil’s Aviation Momentum

International passenger traffic reached 2.2mn in May, up 4.8% from a year earlier and the highest volume recorded for the month.

International flight demand rose by 4.4% year on year, while capacity increased by 3.5%. Demand therefore grew faster than supply, suggesting firm utilisation of international routes.

Latam accounted for 21.8% of Brazil’s international flight demand and increased its international traffic by 15.7%. Tap followed with a 9.5% share, while Azul held 4.8%.

The expansion of international traffic strengthens Brazil’s role as a regional aviation hub. It also supports widebody aircraft utilisation, international maintenance networks and airport infrastructure investment.

For metals markets, aviation growth is important because aircraft manufacturing remains one of the highest-value demand sectors for titanium and nickel superalloys. Strong passenger traffic ultimately supports fleet replacement and expansion when airlines maintain confidence in future demand.

Brazil’s repeated passenger records therefore offer a positive signal for the wider aerospace supply chain. The immediate effect is stronger aircraft utilisation, while the longer-term implication is greater pressure for fleet capacity, maintenance and new aircraft deliveries.

The Metalnomist Commentary

Brazil’s aviation growth is becoming an industrial signal as well as a transport story. Sustained passenger demand should support aircraft utilisation, MRO activity and longer-term aerospace metals consumption across Latin America.

Vale Labor Deal Reduces Strike Risk at Ontario Copper and Nickel Operations

Vale

Vale labor deal discussions have produced a tentative collective agreement with United Steelworkers locals representing production and maintenance workers at Vale Base Metals operations in Ontario. The agreement could reduce strike risk at a key Canadian copper, nickel, cobalt and precious metals production base.

Vale labor deal terms still require union ratification. USW Local 6500 will hold information sessions on 27-28 May, followed by online voting from Thursday morning to Friday evening.

Vale labor deal approval would come just before the current five-year collective agreement expires on 31 May. The timing is important because union members had already voted strongly in favour of a strike mandate earlier this month.

The tentative agreement therefore matters for supply continuity. Vale’s Ontario operations remain an important source of finished nickel and copper for North American industrial and critical minerals supply chains.

Sudbury Operations Remain Strategically Important

Vale’s Sudbury operations include several mines, a mill, smelter and refinery. The complex produces copper, nickel, cobalt and precious metals, making it one of the most important integrated base metals operations in Canada.

The site’s role is especially important because nickel and cobalt remain critical to batteries, superalloys, stainless steel, defence applications and advanced manufacturing. Copper supports electrification, grids, data centres and industrial equipment.

Vale produced 59,400t of finished nickel at Sudbury in 2025. That accounted for about 34% of the company’s total finished nickel output that year.

Sudbury also produced 63,800t of finished copper in 2025, equal to about 17% of Vale’s total finished copper production. Any labour disruption would therefore carry company-level and regional supply-chain significance.

The Port Colborne refinery adds another downstream dimension. It produces electro-cobalt, processes precious metals and distributes finished nickel products.

Ratification Will Decide Supply Continuity

The tentative agreement is not yet final. Union members must approve the deal before it becomes the new labour contract.

That vote will be closely watched because Local 6500 members voted 97.64% in support of a strike mandate earlier this month. Such a strong mandate gave the union significant leverage during negotiations.

A ratified agreement would provide operational stability for Vale Base Metals in Ontario. It would also reduce uncertainty for customers that depend on Canadian nickel, copper, cobalt and refined products.

For North American critical minerals policy, labour stability matters. Governments and manufacturers are trying to build secure supply chains, but mine and refinery output still depends on workforce agreements, site reliability and downstream processing capacity.

The broader market impact depends on the vote. If workers approve the deal, Vale can avoid immediate disruption at a strategically important metals complex. If not, strike risk could quickly return as the current agreement expires.

The Metalnomist Commentary

The Vale agreement shows that critical minerals security is not only about geology, capital or policy. Labour stability at integrated mining, smelting and refining assets is just as important to reliable nickel, copper and cobalt supply.

GKN Aerospace Garden Grove Incident Eases After Evacuation Orders Lifted

GKN Aerospace

GKN Aerospace Garden Grove incident risks have eased after authorities lifted the remaining evacuation orders around the company’s aerospace components facility in California. Around 16,000 residents were allowed to return home after officials determined that an overheated chemical storage tank no longer posed a public threat.

GKN Aerospace Garden Grove incident response focused on a tank containing 7,000 gallons of methyl methacrylate, a hazardous chemical used to make high-strength acrylic materials. Emergency crews cooled the tank and neutralised the material before conditions escalated into a major explosion or chemical release.

GKN Aerospace Garden Grove incident disruption is important because the site produces aircraft transparencies, including cockpit canopies and windows for defence and commercial aircraft. These components serve major programmes linked to Boeing and Airbus.

Officials confirmed there were no MMA leaks and no injuries. The operational focus now shifts from emergency response to recovery planning, customer coordination and supply-chain continuity.

Chemical Risk Disrupted a Sensitive Aerospace Materials Site

The emergency began after a storage tank overheated and a damaged valve complicated efforts to introduce a neutralising agent. Authorities issued the first evacuation order on 21 May because of the risk of a boiling liquid expanding vapour explosion or chemical spill.

That risk was serious because methyl methacrylate is used in acrylic materials for demanding industrial applications. In aerospace, acrylic transparency systems must meet strict optical, structural and durability requirements.

GKN’s Garden Grove facility produces cockpit canopies and windows, which are not commodity parts. They require specialised materials, controlled processing and rigorous qualification before they can be installed on aircraft.

The affected zone included parts of six towns outside Los Angeles, showing how industrial chemical risk can quickly become a community and public safety issue. The mandatory evacuation area was reduced by 65% on 25 May before the remaining orders were lifted.

The incident did not result in a leak or injury, but it still created operational disruption. GKN said it is working with customers on recovery and supply plans.

Aircraft Transparency Supply Requires Tight Recovery Planning

The Garden Grove site supports major aerospace programmes, including Boeing’s Dreamliner and 737 MAX platforms, as well as Airbus’ A350 model. That makes any disruption relevant to high-value aircraft supply chains.

Aircraft transparencies are critical safety components. They must withstand pressure, impact, weathering, temperature variation and long operating cycles while maintaining visibility and structural integrity.

The incident therefore highlights a less visible part of aerospace materials supply. Titanium, aluminium and superalloys usually attract the most attention, but acrylic systems, coatings and transparency materials are also essential to aircraft production.

For Boeing, Airbus and defence customers, the key question is whether GKN can resume normal output without affecting deliveries. Even short disruptions can matter when aircraft supply chains are already managing tight capacity, qualification limits and supplier recovery plans.

The lack of chemical release and the lifting of evacuation orders reduce immediate risk. However, the site may still need inspection, cleanup, regulatory review and production restart checks before full operational recovery.

The incident also reinforces the importance of hazardous material controls at advanced manufacturing sites. Aerospace supply resilience depends not only on raw material availability, but also on safe chemical storage, process stability and emergency response capability.

The Metalnomist Commentary

The GKN incident shows that aerospace supply-chain risk can come from specialised materials and chemical handling, not only engines or metal forgings. For aircraft manufacturers, supplier resilience now includes environmental safety, recovery planning and qualified production continuity.

Sherritt Stake Sale Plan Follows Cuba Nickel-Cobalt Exit

Sherritt

Sherritt stake sale plans have emerged as the Canadian metals firm faces a major strategic reset after moving to dissolve its Moa nickel-cobalt joint venture in Cuba. The company has entered into a non-binding agreement that could allow US investment firm Gillon Capital to acquire 55% of its shares.

Sherritt stake sale terms have not yet been finalised. The company expects the purchase price to be set at a discount to the current share price, with Gillon able to complete the acquisition no later than nine months from closing.

Sherritt stake sale discussions come directly after the company chose to dissolve the Moa joint venture with the General Nickel Company of Cuba. That decision followed new US sanctions authority targeting Cuban entities and sectors, including metals and mining.

The transaction would mark a major ownership shift for Sherritt at a time when its core nickel and cobalt supply chain is under sanctions, fuel and feedstock pressure.

Cuba Sanctions Push Sherritt Toward Strategic Restructuring

Sherritt’s Moa joint venture has been central to its nickel and cobalt business. Ore is mined and processed into mixed sulfide precipitate at Moa in Cuba, then shipped to Canada for refining at Fort Saskatchewan in Alberta.

That cross-border structure has become increasingly difficult. The Moa operation was already affected by fuel supply problems in Cuba, forcing a temporary mining suspension in February.

The situation worsened after the US issued an executive order on 1 May expanding sanctions powers against Cuban entities. Although Sherritt was not directly named, the order allows sanctions on companies operating in Cuba’s metals and mining sector.

Sherritt suspended direct participation in Moa joint venture activities on 7 May. It then announced plans to send a dissolution notice to its Cuban partner on 15 May.

The decision shows how sanctions risk can disrupt critical minerals supply chains even without a direct designation. Shipping, banking, insurance, financing and counterparty confidence can all be affected when operating exposure becomes politically sensitive.

Fort Saskatchewan Refinery Faces Feedstock Uncertainty

Sherritt’s Fort Saskatchewan refinery remains strategically valuable because it can produce finished nickel and cobalt in Canada. However, its feedstock link to Cuba is now the central weakness.

The Moa joint venture supplied mixed sulfide precipitate to the Alberta refinery. If that feedstock route remains disrupted or is dissolved permanently, Sherritt will need alternative material sources to keep refining operations stable.

This matters for North American supply chains. Nickel and cobalt are important for batteries, superalloys, industrial chemicals and defence-linked manufacturing.

The possible Gillon Capital transaction could give Sherritt a new ownership and financing path, but it will still require regulatory approval. The US Departments of State and Treasury do not oppose Gillon’s participation in negotiations, but any later transaction would need their approval.

That condition underlines the political sensitivity of Sherritt’s restructuring. The company’s future will depend not only on investor appetite, but also on sanctions compliance, government approval and feedstock strategy.

For the wider nickel and cobalt market, Sherritt’s situation is a warning. Refining capacity in a secure jurisdiction is not enough if upstream feedstock remains tied to a politically exposed source.

The Metalnomist Commentary

Sherritt is becoming a case study in how sanctions can force a critical minerals company into ownership and supply-chain restructuring. The key issue is whether a new investor can help rebuild the business around secure feedstock for Fort Saskatchewan.

China Boeing Aircraft Deal Signals Trade Thaw but Rare Earth Controls Remain

Boeing

China Boeing aircraft deal confirmation marks a concrete outcome from recent China-US trade talks, but Beijing’s position on tariffs and rare earth export controls shows that strategic supply-chain tensions remain unresolved. China’s Ministry of Commerce said the country will purchase 200 Boeing aircraft under commercial principles.

China Boeing aircraft deal terms also include US commitments to provide sufficient engine and related component supplies. Both sides described aviation as a key sector for mutually beneficial cooperation, giving the agreement wider industrial significance beyond aircraft sales.

China Boeing aircraft deal confirmation is important for aerospace supply chains because Boeing aircraft demand supports engines, titanium, aluminium, nickel superalloys, avionics, landing gear and precision manufacturing. A large Chinese order could improve long-term visibility across several high-value materials and components.

The readout also clarified China’s tariff stance. Beijing said any future US tariffs on Chinese goods should not exceed levels agreed under the joint arrangement reached at the Kuala Lumpur trade consultations.

Aviation Deal Supports Aerospace Supply Chains

The planned purchase of 200 Boeing aircraft could support a broad aerospace supply chain if deliveries move forward smoothly. Aircraft orders generate demand across airframes, engines, forgings, fasteners, castings, electronics and maintenance networks.

For metals markets, the deal is relevant to titanium, aluminium, nickel-based superalloys and specialty steels. Aircraft production and engine supply depend on qualified materials with long approval cycles and strict traceability requirements.

The US side’s commitment to engine and component supply is also significant. Aircraft sales are not only about airframes. Engines, spare parts and related systems determine delivery schedules, airline operations and aftermarket demand.

The agreement may also help stabilise one of the most politically sensitive parts of China-US industrial trade. Aviation has historically been a major commercial bridge between the two economies.

However, execution will matter. Aircraft deliveries require production slots, engine availability, regulatory coordination, financing and customer acceptance. The announcement gives direction, but the supply-chain impact will depend on actual delivery timing.

Tariffs and Rare Earth Controls Keep Strategic Tension Alive

China said future US tariffs on Chinese goods should stay within the levels agreed under the Kuala Lumpur framework. It also said it wants to remove unilateral US tariffs through follow-up negotiations.

Under the earlier arrangement, the US removed a 10% fentanyl-related tariff on Chinese goods and suspended a 24% reciprocal tariff for one year. It also suspended the 50% permeation rule under export controls for one year.

Section 301 tariffs on certain Chinese products remain in place. This means the tariff dispute is not finished, even if both sides are discussing reciprocal reductions for goods worth at least $30bn on each side.

Critical minerals remain the sharper strategic issue. MOFCOM said China applies export controls on rare earths and other materials according to law, and that compliant civilian licence applications are being reviewed.

The materials named include yttrium, scandium, neodymium and indium. These inputs are important for aerospace, defence, semiconductors, magnets, displays, alloys and advanced manufacturing.

US rare earth buyers remain concerned that approved licence volumes are limited. Market participants expect approval cycles could shift from around one week of supply toward biweekly or monthly volumes, but uncertainty remains high.

This means the China-US trade thaw is selective. Aviation cooperation may improve, but Beijing is preserving control over critical mineral flows that give it leverage in strategic industries.

Agricultural products may also enter the reciprocal tariff reduction framework. China still applies 10-15% tariffs on US agricultural goods, which could affect whether private buyers can meet purchase commitments.

The broader message is that China and the US are trying to stabilise trade without fully removing industrial security barriers. Aircraft, agriculture and selected tariff reductions may advance, while rare earths and export controls remain managed pressure points.

The Metalnomist Commentary

The Boeing deal shows that China and the US can still use aviation as a commercial stabiliser. But rare earth licensing remains the real strategic lever, and that will keep aerospace, defence and advanced manufacturing buyers focused on supply security rather than trade headlines.

Sherritt Moa JV Dissolution Marks Break in Cuba Nickel-Cobalt Supply Chain

Sherritt

Sherritt Moa JV dissolution marks a major break in one of the more unusual cross-border nickel-cobalt supply chains linking Cuba and Canada. Sherritt International plans to deliver a dissolution notice to its joint venture partner, the General Nickel Company of Cuba, after expanded US sanctions made continued participation commercially and legally risky.

Sherritt Moa JV dissolution will require the Canadian company to surrender its interests in the Cuban joint venture corporations. The company said immediate dissolution is the only way to preserve its ability to do business.

Sherritt Moa JV dissolution is strategically important because the Moa structure linked Cuban mining and intermediate processing with Canadian refining. Ore was mined and processed into mixed sulfide precipitate at Moa, then shipped to the Fort Saskatchewan refinery in Alberta.

Sherritt expects GNC to owe an equalization payment because it believes the Moa mine is more valuable than the Canadian refinery. That valuation issue could become a key point in the separation process.

US Sanctions Force Structural Exit From Moa

The US directly sanctioned the Moa joint venture on 7 May. The designation followed a 1 May executive order allowing Washington to sanction entities or people supporting the Cuban government across metals, mining, energy, financial services, security and other sectors.

Sherritt had already suspended direct participation in Moa-related activities earlier this month after assessing the implications of the executive order. The direct sanctions accelerated the need for a structural exit.

The company said the dissolution is necessary so it can be considered the sole owner of Canada Refinery Corporation, which owns the Fort Saskatchewan nickel-cobalt refinery. That step is central to preserving the Canadian refining business outside the sanctioned Cuban structure.

The Moa joint venture had been a 50/50 partnership between Sherritt and GNC. Its value came from combining Cuban ore and MSP production with Canadian refining expertise.

The latest move shows how sanctions can fracture supply chains even when downstream refining sits in an allied jurisdiction. Feedstock origin, ownership structure and sanctioned counterparties now matter as much as the location of final refining.

Canadian Refinery Faces Feedstock Repositioning Challenge

The Fort Saskatchewan refinery remains strategically valuable because it produces finished nickel and cobalt. These metals are used in batteries, superalloys, stainless steel, industrial chemicals and advanced manufacturing.

However, the refinery’s historic feedstock route depended on Moa mixed sulfide precipitate. Losing the Cuban joint venture means Sherritt must protect the refinery’s operating future through ownership clarity, alternative feed planning or new commercial structures.

The company had already faced operating pressure before the sanctions escalated. Sherritt temporarily suspended mining operations at Moa in February because of fuel supply problems in Cuba.

That earlier disruption showed the physical fragility of the Moa supply chain. The sanctions now add a legal and geopolitical break to an already strained operating model.

For nickel and cobalt buyers, the key issue is whether Fort Saskatchewan can remain a reliable source of refined metal without direct participation in Moa. The answer will depend on feedstock access, legal separation, inventory management and customer confidence.

The dissolution also highlights a broader critical minerals lesson. Western supply chains can still carry high exposure when mines, intermediates or partners sit in sanctioned or politically sensitive jurisdictions.

The Metalnomist Commentary

Sherritt’s exit from Moa shows that critical minerals security cannot rely on refining capacity alone. The real test is whether the entire chain, from mine ownership to intermediate feedstock and final metal, can survive sanctions, fuel disruption and geopolitical pressure.

ETM Traxys Offtake Deal Targets Spanish Tin, Tantalum and Niobium Supply

Traxys, Energy Transition Metals 

ETM Traxys offtake deal gives the Penouta mine in Spain a potential route back into critical minerals markets. Australia-listed Energy Transition Metals has signed a non-binding agreement to supply Traxys with tin, tantalum and niobium concentrates from the project.

ETM Traxys offtake deal covers 100% of tantalum, niobium and tin offtake from Penouta. Traxys would also receive exclusive rights to market and sell the material to consumers.

ETM Traxys offtake deal is strategically important because tin, tantalum and niobium all sit inside sensitive electronics, aerospace, defence and advanced manufacturing supply chains. A European source of these concentrates could attract buyers seeking supply outside higher-risk regions.

The agreement runs for 12 months but can be converted into a binding six-year offtake once Penouta begins production. ETM is still finalising its acquisition of the mine’s rights and assets from Strategic Minerals Spain.

Penouta Could Rebuild European Critical Minerals Flow

Penouta has a meaningful production history. At its peak, the mine produced up to 60t/month of tin concentrates and 10t/month of tantalum concentrate.

Primary mining stopped in October 2023 after legal action from an environmental group. Tailings and waste processing continued until 2024.

This history matters because Penouta is not only an exploration concept. It has already produced commercially relevant concentrate streams, although any restart will depend on legal, environmental, operating and financing conditions.

Tin is essential for solder, electronics and industrial alloys. Tantalum is critical for capacitors, high-reliability electronics, data-centre chips and aerospace applications. Niobium supports high-strength steel, superalloys and advanced industrial materials.

A restart would therefore add more than mine volume. It would strengthen Europe’s access to strategic minor metals at a time when buyers are reassessing origin risk, traceability and supply-chain resilience.

Traxys’ involvement adds commercial weight. As a global trading house, it can connect concentrate output with qualified consumers, financing channels and strategic buyers.

Traxys Link Adds Strategic Reserve Relevance

Traxys is one of three trading companies selected to procure critical minerals for the US government’s $12bn Project Vault strategic reserve. That gives the Penouta agreement a broader geopolitical dimension.

The offtake does not automatically mean Penouta material will enter a strategic reserve. However, Traxys’ role shows how traders are becoming central to critical minerals security.

This model is increasingly important. Mining companies need offtake and market access, while governments and manufacturers need reliable material flows from politically acceptable sources.

Tin, tantalum and niobium markets have also been volatile this year. Tantalite prices reached record levels in March because of tight supply from central Africa and strong demand from capacitors and tantalum-bearing chips used in data centres.

Tin prices have also risen sharply, supported by investor interest and tighter market sentiment. The London Metal Exchange three-month tin contract has climbed strongly from a year earlier.

These price moves underline the value of diversified supply. Small-volume critical minerals can move quickly when supply is disrupted or when strategic buyers increase procurement.

For ETM, the Traxys agreement could improve Penouta’s commercial credibility. For Traxys, it provides early access to a European source of tin, tantalum and niobium concentrates.

The Metalnomist Commentary

The Penouta agreement shows how strategic traders are moving earlier into critical minerals offtake. If ETM can restart production, Spanish tin, tantalum and niobium could become more valuable as buyers seek traceable supply outside fragile regions.
