Golden Deeps Limited (ASX:GED) has elected to extend the drilling programme planned for the Khusib Springs Copper deposit in Namibia to include drilling at the high-grade Nosib copper-vanadium mine.
The Nosib Block mine was a high-grade copper-vanadium mine located at the western end of EPL3543 16km west of Khusib Springs. Copper mineralisation was discovered at Nosib in 1915 and mined from 1917 to 1920. The historic No 2 shaft was mined on three levels to a depth of 120m.
Golden Deeps geologists accessed the three levels of the mine. The high-grade copper-silver-vanadium-lead mineralisation dips moderately to the north and is hosted by conglomerate and sandstone (mine sequence) in contact with dolomite to the north and basement granite to the south. The mineralisation shows good continuity and remains insitu.
Underground sampling was conducted by Golden Deeps along the drives. Best channel results include: 6m at 9.3% Cu, 4.72% Pb, 7.92% Ag; and 6m at 1.51% Cu, 10.59% Pb, 7.15% Ag, 1.12% V2O5.
In late March the company announced that it had engaged drilling contractor Ferrodrill Namibia for a ~750m reverse circulation (RC) drilling programme at the high-grade Khusib Springs copper-silver deposit.
The extended drill programme at Nosib Block will comprise 11 RC holes on three drill traverses for a total meterage of ~650m at Shaft 1 and 2. Drilling will test copper mineralisation on the contact zone but will also test for mineralisation in the footwall sandstone where mineralisation was mapped along an exploratory underground drive that extends to the south for 50m.
Drilling is planned to commence in April 2021 at both Khusib Springs and Nosib Block, but may be delayed if recent heavy rain in the Otavi Mountainland continues beyond the normal conclusion of the wet season.
