Trinity Tungsten Drilling Campaign Targets Larger Rwanda Supply Base

Trinity, Rwanda

Trinity tungsten drilling has begun at the Nyakabingo mine in Rwanda as the company works to expand one of Africa’s largest tungsten deposits. The campaign is designed to confirm deeper mineralised vein extensions and support long-term mine sustainability.

Trinity tungsten drilling is strategically important because tungsten supply is increasingly tied to defence, aerospace, cutting tools, electronics and energy applications. Rwanda’s role could grow if Nyakabingo moves from semi-industrial production toward full-scale operations.

Trinity tungsten drilling will target depths of about 850m from the surface. The company may consider additional exploration across the licensed area depending on drilling results.

Nyakabingo currently produces 100-110 t/month of wolframite grading 66-70% tungsten. The deposit hosts an estimated 115,502t of recoverable tungsten, with further resource potential at depth.

Nyakabingo Expansion Strengthens African Tungsten Supply

Nyakabingo has been active since the 1930s, making it a long-established tungsten operation with renewed strategic relevance. The current drilling campaign aims to extend the mine’s resource base and support future output growth.

This matters because tungsten supply chains remain narrow and strategically sensitive. Buyers in defence and advanced manufacturing need stable, traceable and qualified sources of tungsten-bearing material.

Trinity is expanding resources while scaling mining and processing capacity. That combination is important because additional reserves only create supply value if mining and processing systems can handle higher output.

The company is also positioning itself for downstream value addition. This reflects a wider shift in critical minerals, where producing countries and miners increasingly want to capture more value beyond raw concentrate.

Rwanda could benefit from that trend. Tin, tungsten and tantalum are all strategically important minerals, and Trinity’s operations give the country a stronger role in supply chains linked to electronics, industrial tools and defence materials.

Wolframite Processing Upgrade Reduces Scale-Up Risk

Trinity recently commissioned a 5 t/hr pilot plant to test an improved wolframite processing flowsheet. The pilot plant is intended to bridge the gap toward a planned 60 t/hr facility under study.

This step is commercially important. Processing performance will determine recovery, concentrate quality, operating costs and the ability to scale output reliably.

The company also installed a closed-loop water treatment system. That supports environmental management and could help improve operating resilience as mining and processing expand.

Trinity has an offtake agreement with US-based Global Tungsten & Powders, while Traxys handles deliveries. This gives the company an established route into international tungsten markets.

The offtake structure also links Rwanda’s tungsten output to western supply-chain security. Global Tungsten & Powders is a key downstream player, and its relationship with Trinity gives Nyakabingo additional strategic relevance.

Trinity’s broader portfolio includes tin and tantalum production from the Rutongo and Musha mines. Rutongo produces 40-70 t/month of tin, while Musha produces 30-40 t/month.

The expansion at Nyakabingo therefore fits a larger critical minerals platform. Trinity is not only developing tungsten. It is building a tin, tungsten and tantalum supply base with growing relevance to electronics, defence and industrial manufacturing.

The Metalnomist Commentary

Trinity’s drilling campaign shows that African tungsten supply could become more important as western buyers seek diversified sources. The real test will be whether Nyakabingo can convert deeper resources and pilot processing into reliable full-scale output.
