Golden Deeps (ASX:GED) is planning channel sampling and shallow diamond drilling at South Ridge Prospect in Namibia after rockchip samples returned up to 680 grams per tonne silver.
The 132 samples come from a 1km-long, 400m-wide northeast-trending corridor at the South Ridge Prospect, within Midas Minerals’ (ASX:MM1) Otavi Project in northeastern Namibia.
Soil sampling already defined the corridor as highly anomalous in copper, zinc and silver.
Top results include 680g/t silver (Ag), 6.67% zinc (Zn), and 2.07% copper (Cu); and 279g/t Ag with 3.3% Cu. Another sample returned 12.57% Zn and 98g/t Ag, while a third returned 11.19% Zn, 97g/t Ag, and 2.1% lead (Pb).
The company links the mineralisation to hydrothermal brecciation and silicification of host dolomite.
South Ridge sits at the eastern end of the Pavian trend, which includes the border inferred mineral resource of 16.2 million tonnes @ 2.12% Zn+Pb and 4.76g/t Ag.
Channel sampling across the ‘strongest’ zones comes first, followed by shallow drilling below trench intersections. The company will consider induced-polarisation (IP) surveying to define deeper targets.
Graceland drilling continues
At the Graceland Prospect, three diamond holes below the Gossan 1 zone intersected disseminated copper and zinc mineralisation within the IP anomaly target area.
The company bases this on visual logging and expects laboratory assays within four to six weeks.
Drilling has started at Gossan 1 East, where an IP anomaly stronger than the one below Gossan 1 sits offset from the copper gossan.
The company will then test Gossan 1 Far East, the ‘strongest IP target to date’, which has no surface expression. Shallow drilling will also test Gossan 1 Southwest.
CEO Jon Dugdale says South Ridge is the second ‘Tsumeb-type’ prospect identified after Graceland.
“Trenching and channel sampling is planned across the broad zones of mineralisation, and we look forward to drill-testing below the most strongly mineralised zones,” Dugdale says.
Golden Deeps is an Australian explorer advancing a portfolio of gold, copper, silver, zinc, and vanadium assets across the Lachlan Fold Belt in New South Wales and Namibia’s Otavi Mountain Land, with additional ground in Ontario, Canada.
