THE DRILL SERGEANT: Middle Island Resources (ASX: MDI) advised of assay results from infill and extension RC (reverse circulation percussion) drilling recently completed at the Wirraminna gold deposit, within the company’s wholly-owned Sandstone gold project in Western Australia.
Middle Island’s Wirraminna deposit is situated one kilometre from the company’s 100 per cent-owned, Sandstone 600,000 tonnes per annum gold processing plant.
“The results of the RC drilling have extended the depth potential of the deposit, but are otherwise broadly consistent with expectations and previous drilling results,” Middle Island Resources said in its ASX announcement.
“However, holes drilled to verify historic, broad, high-grade intervals again proved unsuccessful.”
Highlight RC drill intercepts included:
7 metres at 1.76g/t gold from 68m;
6m at 6.62g/t gold from 84m;
14m at 1.82g/t gold from 82m;
14m at 1.8g/t gold from 42m, including 1m at 18.2g/t gold from 52m; and
5m at 2.51g/t gold from 41m.
An existing Mineral Resource estimate for the Wirraminna deposit sits at 550,000 tonnes at 1.3 grams per tonne gold for 23,000 ounces gold (at a 0.5g/t lower cut-off grade).
Around 55 per cent of this is classified as an Indicated Mineral Resource, whilst the balance is in the Inferred category.
