Reivilo Kimberlite Cluster

The Reivilo project in South Africa’s North West Province signifies BMIN’s expansion beyond the Limpopo Fissure Mines into a unique kimberlite zone of the Kaapvaal Craton. Located approximately 110 km north-east of Petra’s Finsch Mine, the area was previously explored by De Beers and Petra. BMIN received a five-year Prospecting Right in 2022 over the farm hosting the Reivilo kimberlite cluster—comprising three pipes of roughly 3.1 ha, 1.7 ha, and 0.9 ha within 250 m of each other, indicating a compact kimberlite field.

The pipes were drilled by Petra Diamonds, whose indicator-mineral results showed G10 and eclogitic garnets, both strong markers of diamond potential. G10 garnets, in particular, form under deep mantle conditions favourable for diamond stability. Although promising, the project probably fell below Petra’s development threshold. Recognising the opportunity, BMIN secured both the prospecting licence and a Data Licence Agreement granting access to Petra’s historical data in exchange for a 3% production royalty. This arrangement provides BMIN with extensive geological information at no upfront cost, with payment only triggered by future production.
