Norwest Minerals Limited (ASX: NWM) is preparing to commence RC drilling designed to test for gold mineralisation extending well below the shallow Bulgera open pits in Western Australia.
The Bulgera project includes a near-surface gold resource of 2.9Mt @ 1.0 g/t for 93,880oz Au, with minimal historical drilling below 100 vertical metres.
CEO, Charles Schaus, said Norwest’s 5,000m reverse circulation (RC) drilling programme (through targeted ~250m deep RC holes) will test for extensions to known gold mineralisation by drilling +150 vertical metres below the three-existing shallow Bulgera open pits.
It is very exciting to get this high-priority high- impact RC drilling programme underway,” Mr Schaus said.
“The implications associated with drilling success +150m down-dip of the current near surface gold resources include a significant jump in resource size and ongoing growth prospects.”
The Bulgera gold trend is the extension of the Plutonic (+5.5moz) and Vango (+1moz) mafic- ultramafic mine sequence where drilling has shown that gold tenor increases with depth.
Nearby, Vango’s drilling within the mine sequence has consistently shown that the highest gold grades are located below 100m.
Norwest’s planned RC drilling program (through targeted ~250m deep RC holes) will test for extensions to known gold mineralisation by drilling +150m below the three existing shallow open pits.
At Bulgera there has been no drill testing for gold mineralisation directed along the contact between the granite-mine sequence contact.
Recently located structural interpretations from AMAG Data show first and second order mineralisation structures extending through the Bulgera pit area and across the Granite contact. Norwest has planned both RC and aircore drilling along the granite contact to test for PHB and Trident style gold mineralisation.
