Massive hits outline high-grade gold zone at Norwest’s Bulgera project

May 11, 2021 | News

Norwest Minerals is furthering its understanding of a high-grade gold zone at the Bulgera gold project on the back of exciting assays reported from drilling in March.  

The assays taken from below the historical open-cut deposits at Bulgera, located at the northeast end of the Plutonic Well greenstone belt in WA, delivered outstanding results for Norwest (ASX:NWM).

This included one hit of 3m at a whopping 30 grams per tonne gold within a broader zone of 16m at 7.3g/t from 194m. That hole, BRC 21015, ended in 18.5g/t gold at 210m.

Another high-grade intersection of 6m at 11.8g/t gold, including 3m at 22.4g/t, was reported from 218m in BRC 21013.

The latest results occurred along strike and down-dip from February’s high grade discovery hole BRC21001, which hit 5m at 15g/t from 194m. Further drilling is planned to test further down-dip potential.

Norwest CEO Charles Schaus said the results of the program were extremely promising and highlighted Bulgera’s potential.

“We are excited with these assay results from our March 2021 drilling program,” managing director Charles Schaus said.

“The continuity of these relatively shallow, wide, high-grade drill intersections demonstrates Bulgera’s significant potential, especially with one of the holes ending in very-high grade mineralisation at only 210 metres.

“We are very keen to recommence drilling to test for downdip extensions of this gold-rich zone.”

A fourth hole – BRC21014 – showed no significant mineralisation, but analysis is being undertaken to understand if the hole was ended short of the gold mineralised zone.

The latest results were reported from a 5000m reverse circulation drilling program commenced late last year to determine if gold mineralisation beneath the historical Bulgera and Mercuri gold deposits continued at depth.

That came on the back of a company review of gold deposits and prospects located along the Marymia mine sequence which showed widths and gold grades of drill intercepts appeared to increase below 100 vertical metres.

On top of the standout results from Bulgera, Norwest believes multiple gold lodes intersected below Mercuri have the potential to generate high tonnages per vertical metre, despite returning low to moderate gold grades so far.

Most of these intercepts can also be extended up-dip and connected to gold intercepts encountered in past drilling programs.

Norwest’s Bulgera tenements include a near-surface resource of 2.9 million tonnes (Mt) at 1.0 g/t for 93,880 ounces of gold, with minimal historical drilling completed below a depth of 100m.

The project spans two exploration licences, spanning a total 36.8km2.
