DGO Gold (ASX: DGO) has kicked off about 6,000m of drilling at the Pernatty project in South Australia as it continues its search for Zambia copper belt-style wealth under its farm-in to ground held by silver play Investigator Resources (ASX: IVR).
DGO says its recent drill program confirmed the presence of that Zambia-style copper at the Moseley prospect with proof-of-concept holes returning 4m at 0.41% copper, 0.04% cobalt and 10.6 grams per tonne silver from 73m down hole.
In March DGO drilled 44 RC holes for 3,733m at Pernatty, with copper grades above 0.1% intersected in all three areas drilled in the target transition zone.
It was at Moseley that the best results were found, where three holes over 1.5km had 1m assays greater than 0.5% with associated elevated cobalt and silver at depths between 50m and 80m.
At the Maslins prospect three holes had 1m assays greater than 0.7% copper, with the best intersection of 0.7% copper and 15g/t silver at a depth of 146m.
100km strike zone being explored
The third prospect drilled in March, Winnie Pinnie, has a 2.5km by 5km target area untested by previous drilling.
Overall, DGO is targeting a 100km-plus zone at Pernatty.
Pernatty, lies 55km southwest of the Carrapateena copper-gold mine operated by OZ Minerals (ASX: OZL).
DGO’s agreement with silver play Investigator Resources allows for the farm-in company to spend $6.36 million over five years to earn the 80%.
Setting has ‘many’ similarities to Zambia copper belt
The company has said previously that the basin setting at Pernatty has many similarities with the edges of the Katangan Basin in the central African copper belt which hosts such deposits as Chambishi, which contains 40Mt at 2.6% copper.
The former British-owned minerals house Selection Trust in 1976 intersected, immediately east of Peratty, 1.9m at 1.7% copper from 185m down hole when exploring for sedimentary copper, but this was not adequately followed up before the. tenement was relinquished in 1978.
The Pernatty tenements are located in the Eastern Gawler Craton, South Australia, within the Stuart Shelf Copper-Gold Province.
Ten are 100% held by DGO and five are under a binding heads of agreement with Investigator Resources, with a total area of 4.730sq km.
The area on the Stuart Shelf lies under cover.
The new wide-spaced reverse circulation drilling will test 10km of strike length, the program to take about six weeks with results due in late November.
