The Bisesero Project

Since 2024

In 2024, Tri Metal completed a desktop airborne geophysical study with an external geophysical consultant. This study involved merging ground magnetic data with B2B airborne magnetic data to enhance geological understanding, providing greater insight than could be derived from ground data alone, and identify areas with higher mineralization.

In 2025, Mawarid plans on conducting aerial geophysical surveys with the objective of defining target areas by applying the most cost-effective method to cover large areas of Bisesero rapidly and efficiently. Additional groundwork will be carried out in the anomalous areas to identify more drilling targets, which will ultimately help delineate areas with potential mineral resources.

The Bisesero Project is held 100% under Mawarid’s wholly owned Rwandan registered subsidiary Tri Metals Mining Rwanda Limited (“TMMRL”).

Promising Results in Rwanda’s Mineral Riches

Historically, the concession area has been artisanally mined for the 3 T’s Tin (Sn), Tantalum (Ta) and Tungsten (W) since early 1930s.

In 2019, Mawarid completed a 2,000 meters diamond drilling program to test highly advanced exploration targets on the Bisesero tenements, and the results were encouraging.

Additional geological work is required to better understand and define the complex structural geology and mineralization style of the prospect. Rwanda Mines, Petroleum and Gas Board has approved two periods of care and maintenance for the Bisesero Project until De
