1. Preamble

Trinity Metals Limited (the Company) is a privately owned company engaged in the mining and exploration of tin, tungsten, tantalum and lithium in Rwanda. The Company is currently developing and operating three mining complexes in Rwanda near the city of Kigali: Rutongo Mine (tin); Trinity Nyakabingo Mine (tungsten); and Trinity Musha Mine (tin and tantalum, with lithium exploration).

Trinity Metals is currently seeking international investment to fund the expansion, modernisation and mechanisation of the existing operations. In support of this, Trinity Metals is in the process of implementing an ISO14001/45001-aligned integrated SHEC management system. The 2024 ESIAs for all three of the mines included specialist hydrology, geochemistry and geohydrology assessments. These informed the ESIA outcomes and Environmental and Social Management Plans (ESMPs). The ESMPs make provision for surface and groundwater monitoring programmes.

Trinity Metals requires the services of an experienced and accredited laboratory to assist us with routine analysis and reporting of our water samples.
