A further 22 drill holes for 2,425 metres has enabled the company to upgrade the Pinnacles East resource to 609,000 tonnes at 4 g/t gold for 78,000 ounces.
The open-pit resource is now 159,000 tonnes at 2.4 g/t for 12,000 ounces and the underground resource is 450,000 tonnes at 4.6 g/t for 66,000 ounces.
This resource from the surface down to 200 metres now contains more than 90% indicated mineral resources with additional drill hole data allowing for a more selective interpretation of the geological controls on the mineralisation.
Pinnacles East mineral resource model
Results “enhance" project
Managing director Andy Tudor said: “I am very pleased with the mineral resource in terms of both tonnes and particularly grade.
“These results, in conjunction with the current strong Australian gold price, further enhance the strength of the Pinnacles project and its ability to produce a robust and viable gold mining operation.
“Due to the pre-existing ore sales agreement with Saracen, there is very low capital expenditure required to initiate mining with any ore mined to be processed through Saracen’s Carosue Dam Operation”.
Since entering into the JV with Saracen Mineral Holdings Limited (ASX:SAR) (OTCMKTS:SCEXF), Nexus has drill tested the depth and continuity of the potential high-grade mineralisation through depth staged drill programs.
These programs have intersected mineralisation from surface to some 350 metres vertical depth and tested the strike extent of the resource.
Mining studies advancing
Nexus is determining the feasibility of the open-cut potential of the Pinnacles East gold resource area, with deeper mineralisation considered as a potential underground operation.
Consultants have been engaged to undertake a pit optimisation study and mine development plan options to assist in determining the financial viability of establishing a gold mining operation.
Due to the pre-existing ore sales agreement with Saracen, there is minimal capital expenditure required to initiate mining with ore mined to be processed through Saracen’s Carosue Dam operation.
Geotechnical, metallurgical and hydro-geological test work along with environmental baseline studies are being undertaken to assist in determining mine development options.
Nexus’ tenement package at Pinnacles is largely underexplored and begin less than 5 kilometres to the south of, and along strike from, Saracen’s more than 5 million-ounce Carosue Dam mining operations and operating Karari underground gold mine.
