Golden Deeps Limited (ASX:GED) has drilled an exceptionally thick, 90m copper-silver intersection from diamond drillhole KHDD006 at the Khusib Springs deposit in Namibia.
The intersection came was drilled in the first deeper diamond drillhole at the Khusib Springs copper-silver deposit in the Otavi Mountain Land Copper District (OMLCD) of Namibia.
The diamond drillhole, KHDD006, produced the following intersections:
– 90m @ 0.8% CuEq (0.3% Cu, 52.3 g/t Ag, 0.06% Zn, 34.4 g/t Sb) from 389m downhole,
Including: 69m @ 1.0% CuEq (0.4% Cu, 63.7 g/t Ag, 0.07% Zn, 42.1 g/t Sb) from 402m,
Including: 28m @ 1.5% CuEq (0.5% Cu, 101 g/t Ag, 0.1% Zn, 80.8 g/t Sb) from 402m,
Including: 10m @ 2.2% CuEq (0.8% Cu, 150 g/t Ag, 0.15% Zn, 110 g/t Sb) from 411m.
The thick zone of copper-silver mineralisation intersected by KHDD006 is approximately true-width and occurs across the brecciated T3 dolomite / T2 limestone contact, which is the same position as the Khusib Springs deposit located up-dip across the interpreted wrench fault.
The Khusib Springs mine produced 300,000t at 10% copper and 584 g/t silver before closing in the early 2000s.
A second high-grade zinc intersection was produced from a footwall structure of 3.0m @ 5.8% Zn, 1.8% Pb, 11.5 g/t Ag, 12.9 g/t Sb from 502m downhole (including 0.76m @ 16.0% Zn, 3.1% Pb, 21.4 g/t Ag 22.9 g/t Sb).
This highlights the potential for high-grade zinc resources at Khusib Springs. This is supported by the previously announced shallow intersection in KHDD001 of 11.86m @ 3.3% Zn, 14.7 g/t Ag, 0.13% Cu, 0.17% Pb from 10.34m downhole (including: 5.0m @ 7.5% Zn, 20.9 g/t Ag, 0.08% Cu, 0.24% Pb)
“This 90m intersection of copper-silver mineralisation below the Khusib Springs mine demonstrates potential for major extensions to the deposit,” CEO, Jon Dugdale, said.
“The intersection of high-grade zinc mineralisation in the footwall of the copper-silver zone adds to the resource potential of this zone.
“We look forward to the results of the second deeper hole, KHDD0007, that also intersected a very thick sulphide zone.
“We’ll then integrate the geophysical program results before planning targeted follow-up drilling.”
A second deeper hole, KHDD007, which was drilled 30m to the southwest of KHDD006, intersected a very thick zone of sulphide mineralisation from 374m to 535m downhole (161m) including zones of disseminated and/or euhedral crystals of tennantite and chalcopyrite across the T3 dolomite / T2 limestone brecciated contact at around 430m. The hole also intersected a lower zone of ‘well distributed’ medium grained sphalerite (zinc sulphide) from 487m to 500m downhole.
Drillcore from KHDD007 has been submitted for analyses at Intertek laboratories and results are expected early in the new year.
Evaluation and modelling of the results of this programme, as well as modelling of the results of ongoing geophysical programs along strike from Khusib Springs, will lead to follow up programs to expand the resource potential of the deposit and test for repeats and/or extensions of the mineralisation along strike.
