Musgrave Minerals Ltd (ASX:MGV, OTC:MGVMF) has hit bonanza-grade gold during infill diamond drilling at the White Heat prospect, an exploration target within its cornerstone Cue Gold Project in Western Australia’s Murchison District.
The gold explorer unsurfaced up to 303.2 g/t gold as it drilled at the near-surface gold target, with mineralisation intersected over a 70-metre to 100-metre strike extent.
As part of its validation phase, Musgrave recently completed three diamond drill holes at White Heat, where the first two holes unsurfaced very high gold grades.
Mineralisation at the target remains open down plunge, with further drilling scheduled to commence next month.
Potential to discover additional high-grade gold lodes
Musgrave Minerals managing director Rob Waugh said: “These are bonanza results and support our previous drilling at the high-grade White Heat deposit.
“The White Heat lode is in a similar orientation and geological setting to the high-grade Starlight Lode only 400 metres to the north but is currently not included in a mineral resource estimate.
“These results from White Heat further highlight the potential to discover additional high-grade gold lodes within the project area.
“The combination of near-surface high-grade lodes like White Heat and Starlight, together with the large, moderate grade Big Sky-style targets are expected to complement each other and enhance the future development potential of the project.
“Exploration is continuing to deliver strong results and add value for our shareholders.
“Drilling will resume at White Heat in September as we continue to extend the plunge of the mineralisation.”
White Heat proves white-hot
Significant new gold intersections from the White Heat target include:
- 8.4 metres at 6.8 g/t gold from 27.3 metres, including 1.2 metres at 37.2 g/t from 27.3 metres;
- 6.8 metres at 17.8 g/t from 47 metres in the hanging wall lode, including 0.7 metres at 112.9 g/t from 48.1 metres; and
- 3.4 metres at 107.6 g/t from 74.6 metres in the footwall lode, including 1.2 metres at 303.2 g/t from 74.6 metres.
The White Heat mineralisation has a similar strike to the Starlight lode at Break of Day, 400 metres to the north, and is hosted within a basalt package thought to be the same stratigraphy as that hosting Starlight.
A leached, near-surface zone is present, where gold is depleted in the upper saprolite, while the mineralisation is open down plunge.
Ultimately, the latest results prove that drilling at White Heat continues to intersect very high-grade gold mineralisation near the target’s surface.
While the first two validation holes hit the bonanza gold grades, the third diamond drill hole did not extend deep enough to intersect the projected position of the high-grade footwall lode.
What’s on the cards?
At its whole-owned tenements, Musgrave is conducting reverse circulation (RC) drilling at the Big Sky prospect in a bid to better define the target’s gold mineralisation.
Roughly 129 holes have been drilled to date, with further assays expected early next month.
In tandem, a follow-up RC program to define the basement source of gold anomalism at Target 14 is also underway, with more results anticipated in September.
On top of that, one-metre resamples from six-metre composite samples taken across roughly 55 RC drill holes from both prospects are expected mid-next month.
Finally, works to progress the pre-feasibility level studies at Break of Day and Lena continue, with additional metallurgical and geotechnical test work underway, while the first phase hydrological drilling has been successfully completed.
Over at the Evolution joint venture, follow-up diamond drilling at the West Island and Austin North prospects on Lake Austin remains ongoing, with four holes completed in the current program and assays pending.
Simultaneously, aircore drilling on Lake Austin is underway to define additional targets for basement diamond drill testing. Results for this campaign are also anticipated.
