Norwest is expecting a substantial increase in resources for its Bulgera gold project after drilling extended a new lode more than 400m downdip of the open pit.
The top result from the first three diamond holes was 11.3m grading 3.25 grams per tonne (g/t) gold from 260m including 4m at 4.5g/t gold from 260m and 3.3m at 5.3g/t gold from 268m in BDD21003.
Results from the other two holes, which were drilled closer to surface, also returned significant intersections of 16.5m at 1.2g/t gold from 128m and 3m at 4.1g/t gold from 166m (BDD21001), and 6m at 2.07g/t gold from 195m (BDD21002).
Here we go
Assays from the remaining four deep diamond holes are expected within the coming weeks following which Norwest Minerals (ASX:NWM) will begin resource modelling of the new Bulgera gold mineralisation.
“Assay results from the first three diamond holes confirms that strong gold mineralisation extends beyond 400 metres down dip of the shallow Bulgera open pit,” chief executive officer Charles Schaus said.
“Once the gold assays from the remaining four diamond holes are received (over the coming weeks), the company will commence re-modelling the Bulgera gold resources which should add considerably to the current, 94,000-ounce, gold resource reported in April 20202.”
The seven-hole diamond program, consisting of 953m of reverse circulation pre-collars and 1,406m of diamond tails, appears to have been remarkably successful with all holes intersecting the main mineralised zone as expected.
Holes BDD21001 to BDD21003 intersected two mineralised zones returning wide intercepts of moderate gold grades from within the main shear zone and high gold grades from a deeper, relatively narrow zone hosted by white quartz vein with low-moderate sulphides.
The wide shear and white quartz zones logged in these holes likely correspond to the two high-grade intercepts reported in hole BRC21015 of 16m at 7.3g/t gold from 194m and 3m at 30g/t gold at the end of the hole.
Bulgera’s remaining holes test for gold mineralisation at or below 400m downdip of the Bulgera open pit, being well below any previous drilling undertaken across the Bulgera Project.
Norwest is now sourcing for a rig to undertake the Phase 2 diamond drilling program that is scheduled to start in March or April.
This will test the continuation of the target shear zone a further 300m down-dip from the Phase 1 holes.
Pre-collars for the Phase 2 holes were previously drilled in October 2021.
