This Tanganyika Gold Project is a vein-hosted gold project near Lake Tanganyika in south-eastern DRC. The presence of gold in the area was detected and preliminary exploration performed in the 1940s …

Several phases of geological exploration
Historically the project has seen several phases of exploration including geological mapping, soil sampling, grab sampling, trenching and limited drilling. Phase 1 of the project consisted of validating all available data on the project followed by combining all the validated data into a usable database. This was followed by phase 2 which consisted of a site visit that aimed to verify the historical mapping, trenching, drilling and sampling data. This was followed up by metallurgical test work on samples obtained from the field.

Phase 3 consisted of developing a high-level 3D geological model and block model for the project. Using the grade block model an economic evaluation was performed looking at various realistic mining methods and focusing on a small-scale rampable operation.
Results show project has a minable resource
The results showed that even with conservative parameters this project has a minable resource with significant upside potential if exploration is furthered. Minrom is excited about the next phases of exploration and the proving up of resource and reserve numbers. Minrom has recommended that further delineation and definition diamond drilling be performed on existing targets as well as further mapping, soil sampling and geophysical studies on extended targets. This will significantly reduce the risks associated with proposed small-scale mining in the project area.
