Location: Burkina Faso | Resource: Gold
A significant milestone was reached recently when Golden Rim Resources announced a maiden mineral resource at the Banouassi gold prospect at its Kouri project in Burkina Faso.
Kouri lies on a major mineralised fault zone that extends to the north-east into western Niger, where the 2.5 million ounces (Moz) Samira Hill gold deposit is located. To the south-west, the fault zone is connected to the Markoye Fault system, which controls several large gold deposits in Burkina Faso, including Kiaka (5.9Moz gold), Bombore (5.2Moz gold), and Essakane (6.2Moz gold).
According to independent experts RPM Global, the deposit contains an estimated indicated and inferred mineral resource of 20.8 million tonnes at 1.5 grams per tonne of gold (g/t Au) for one million ounces of contained gold at a 0.5g/t Au lower cut-off grade. The contained gold in the mineral resource is almost double the size of the previous exploration target. About 15.3% of the mineral resource is classified as indicated resource and the remainder is classified as an inferred resource.
A reverse circulation (RC) drilling programme continued at Banouassi subsequent to the release of the mineral resource. The drilling programme comprised drilling additional targets in the immediate resource area, targeting additional shallow high-grade gold mineralisation.
According to the company, the drilling confirmed the considerable potential for additional gold mineralisation outside of the mineral resource area to be outlined. This includes the discovery of a new high-grade gold lode (6m at 25.2g/t gold) associated with a 1.2km-long induced polarisation (IP) geophysical anomaly that lies 100m south-east of the mineral resource. The new high-grade gold lode was discovered in an area where no previous RC drilling had been conducted and where previous auger drilling returned results up to 2 017 parts per billion (ppb) and 1 593ppb gold under shallow soil cover. The ongoing RC drilling programme continues to deliver results indicating potential strike and depth extensions to the mineralisation.
