Gold developer and explorer Middle Island Resources announced maiden mineral resource estimates for its Sandstone gold project in Western Australia has hit 746,500 oz.

MiddleIsland Sandstone drillingSandstone’s new Ridge and McClaren satellite open pit deposits collectively added 24,500 oz. of gold. Ridge and McClaren represent the final two (of five) new satellite open pit deposits quantified by Middle Island’s 50,000 metre drilling campaign in 2020.

Both deposits are being optimised to determine the in-pit mineral resources likely to contribute to ore reserves in Sandstone’s current feasibility study.

“The Ridge and McClaren satellite open pit deposits represent the final mineral resource estimates contributing to the current [feasibility study], which is scheduled for completion in January 2021,” commented Rick Yeates, managing director. 

“Prior to commencement of the 2020 drilling campaign, the anticipated best case scenario was a doubling of Sandstone’s open-pit mineral resources which, with the addition of Ridge and McClaren, we have now achieved. This is an extremely pleasing outcome that should ensure a positive [feasibility study] outcome and a project recommissioning in 2021.”

Yeates noted that the Phase 3 drilling campaign is schedule for completion late next month.
