Golden Deeps Ltd has appointed international geophysics contractor Terratec to conduct an Induced Polarisation (IP) and conductivity survey across its Graceland Prospect in Namibia’s Otavi Mountain Land Critical Metals Province.
“We are delighted to have secured the services of highly-regarded international geophysical contractor Terratec to carry out our IP-Conductivity survey, which is designed to detect multiple high-grade sulphide targets at Graceland,” said CEO Jon Dugdale.
The survey, due to begin within three weeks, will cover the full 2km mineralised corridor to depths of 300 metres, targeting both shallow and deeper sulphide zones containing copper, silver, zinc, lead, and germanium.
Dugdale said results are expected within four to six weeks and will guide drilling plans already under consideration.
Exploration at Graceland has recently been strengthened by the discovery of a 100m by 20m mineralised gossan zone on the western extension of the Gossan 1 corridor.
The outcrop contains visible malachite veins and clots, with channel sampling underway. This zone will be included in the upcoming IP survey.
At Gossan 1, rockchip samples have returned grades of up to 38.3% copper, 35.4% zinc, and 1,130 grams per tonne silver. Dugdale said these results highlight the potential of the corridor for polymetallic sulphide mineralisation.
To the east, Gossan 1 East assays have shown up to 47.3% copper, 7,792 grams per tonne silver, and 224 grams per tonne germanium, while at Gossan 2 sampling has delivered grades of up to 29% copper, 32.4% zinc, 34.1% lead, 3,179 grams per tonne silver, and 97 grams per tonne germanium.
“This combination of high-value metals highlights the corridor as a multi-commodity target with potential for significant economic value,” Dugdale said.
He noted that artisanal workings had been observed across several gossan zones, with geology resembling the discovery gossan at the world-class Tsumeb Mine, located 20km north of Graceland.
Tsumeb ultimately produced 27 million tonnes of ore grading 4.3% copper, 10% lead, 3.5% zinc, 95 grams per tonne silver, and 50 grams per tonne germanium.
“The results of the channel sampling and the initial outcomes of the IP survey will be available within the next four to six weeks. We have already identified several drilling options for testing both shallow and deeper targets, which should enable us to drill-test these very exciting target zones within the current field season,” Dugdale said
