Musgrave unearths eyewatering 1,040g/t gold in WA’s Murchison

There is clearly no end to the extremely high-grade gold that can be found in Western Australia’s mineral-rich Murchison region, with Musgrave Minerals reporting a bonanza 1,040g/t gold from further drilling at the White Heat-Mosaic prospect.
The Break of Day Trend at Musgrave Minerals’ (ASX:MGV) Cue gold project is already one of the highest grade structures in Australia, with very few undeveloped gold resources even coming close.
And it continues to deliver for the Aussie explorer, notching a new record hit of 1m at 1,040 grams per tonne (g/t) from within a broader intercept of 7m at 149.7g/t from 143m during extensional reverse circulation drilling.
“These are another set of very strong results from White Heat-Mosaic, part of the high-grade Break of Day Trend,” managing director Rob Waugh said.
“It would be hard to find better results from a recent Australian exploration program and the Cue gold project is fast becoming one of the richest undeveloped high-grade gold deposits in Australia.”
This same program also returned other high-grade hits including 3m at 25.8g/t from 184m and 5m at 6.9g/t from 135m
Musgrave has so far defined a high-grade resource for the Break of Day Trend deposits of 982,000 tonnes at 10.4g/t for 327,000oz of gold, with 70% in the higher confidence indicated category.
Of that resource, the White Heat-Mosaic prospect hosts 185,000 tonnes at 11g/t for 65,000oz of gold, which has so far only been defined down to 160m.
Just a couple of months ago, Musgrave beat analyst predictions with a 41% increase in the resource at its broader Cue project to 12.3 million tonnes at 2.3g/t for 927,000oz of gold.
These latest results set the company up nicely for bolstering that resource even further and taking the project into 1Moz territory.
The deposits along the Break of Day Trend are all near surface and confined as quartz lodes within a high-titanium basalt unit that extends more regionally beyond the known mineralisation.
Musgrave undertook further drilling at White Heat-Mosaic to infill and extend that mineralisation. RC infill drilling returned high-grade intercepts of up to 230.5g/t that extended for 2m within a broader 4m at 116.5g/t from just 50m.
Meanwhile, diamond infill drilling returned a top intersection of 0.5m at 365g/t from 115.1m.
Musgrave also discovered a new splay lode that threw up a hit of 6m at 14g/t from 127m.
Waugh said Musgrave would continue to define these new lodes with further drilling to determine the extent and potential of the new discovery.
“We are continuing to grow our understanding of the system and the controls on mineralisation,” he said. “Exploration is continuing while we also progress development studies on our existing resources at Cue.”
There is still plenty of blue sky at Cue, with mineralisation remaining open down plunge. Musgrave plans to start further infill and extensional drilling along the Break of Day Trend this week.
Musgrave is also continuing drilling at the Amarillo prospect, with further results pending and a maiden resource due for release in early 2023.
