Brazil Minerals, Inc. announced recently that its extensive drilling programme at one of its several mineral rights in the Jequitinhonha River Valley in northern Minas Gerais state in Brazil has yielded “alluvial material with a high likelihood for diamonds in over 57% of the drill holes executed”. 

Marc Fogassa, CEO of the Brazil Minerals, stated, “Our identification of an initial diamond-rich zone within a gold mineralisation area is a very good outcome. It is relevant to note that this particular mineral right has 1,310 acres and this drilling campaign covered only a small portion of such area.”

The Company said it had drilled 35 holes spaced 30 to 50 meters apart utilising a Banka 4-inch percussion rotary drill.

The Company had earlier reported that all drill holes were positive for fine gold. “Further analysis of the campaign’s results and inspection of collected samples indicate that there is a diamond-rich zone in the area as well,” Brazil Minerals stated. “Satellite markers for diamonds, such as limonite, rutilite and tourmalinite, among others, were observed in all samples recovered within this diamond-rich zone. The Jequitinhonha River Valley where this mineral right is located has been a well-known source of gem-quality alluvial diamonds for over two centuries.”
