How resourceful of them.
Black Mountain Resources (LSE:BMZ) have announced further exploration success at their New Departure project with silver grades exceeding 5,000g/t.

The company had previously made number of announcements this year of positive grab sample results at its New Departure mine in Montana. Today, the company announced the results of grab samples from the recently opened-up Blue Dot Level which, significantly, will give access to the Bonanza Zone as well as the Main Zone historical mining blocks.

In the current sampling programme, assay results from a further six grab samples have been released, with silver grades varying between 781g/t and 5,194g/t (with additional gold, copper, lead and zinc credits). These high grades underpin the potential of the Bonanza Zone, are in line with the company’s extensive historical database, and support the company’s ongoing efforts to bring the mine into production.

Black Mountain now has access to three historic mineralisation blocks, and the main decline is continuing to be developed towards the Main Zone. The first phase of underground surveying has been completed and 3-D mine modelling should be finalised in the next few weeks.

Optimised flotation metallurgical testing has successfully achieved silver recoveries of over 85%, and the company believes that it will be able to achieve 90% recoveries in the near term. Black Mountain continues to undertake CIL testwork. Silver recoveries of over 89.5% have been achieved with low cyanide and lime consumption.

In a statement Black Mountain said that “Today’s announcement continues to reinforce the high-grade potential of the resource at New Departure” . The company said “We look forward to providing further updates on the completion of metallurgical testing, toll treat arrangements, the 3-D mine model and commencing development ore over the coming weeks”, so investors can hopefully anticipate further positive news in the near term.
