Special Report: Norwest has resumed its deep drilling campaign at the Bulgera gold project in WA that has already returned some intriguing gold hits.
All nine of the initial holes totalling 1,400m struck multiple zones of gold with notable intersections of 2m at 7.1 grams per tonne (g/t) gold from 42m and 16m at 1.6g/t gold from 84m.
However, drilling was interrupted due to the rig suffering severe mechanical problems.
Norwest Minerals (ASX:NWM) then engaged veteran driller West Drill to complete the remaining 13 holes to continue testing for deeper extensions of known mineralisation by drilling about 150m below the Bulgera and Mercuri open pits.
The deepest hole has already been completed, reaching a depth of 276m with alteration typical of hosting Bulgera gold mineralisation intersected from 235m to 255m. Assay results are expected in about three weeks.
“West Drill are very experienced in the Marymia/Bulgera area having worked for Vango Mining over the past few years, thus we expect the remainder of the Bulgera RC program to progress smoothly,” Norwest chief executive officer Charles Schaus noted.
“Intersecting gold mineralisation in these deeper RC holes will be a game changer for the Bulgera gold project and Norwest Minerals.”
Big gold potential
Bulgera has a current resource of 2.9 million tonnes grading 1g/t gold for 93,880oz of contained gold and is located within the same trend as the +5.5 million oz Plutonic and +1Moz Vango mines where drilling has shown that gold tenor increases with depth.
Vango Mining’s (ASX:VAN) drilling in particular has consistently shown that the best gold grades are located below 100m.
The Bulgera project tenements have historically produced 440,799 tonnes of ore at 1.65g/t for 23,398 ounces of gold across two production windows – 1996-1998, and 2003-2004.
