Mammoth Minerals reports multiple significant gold intercepts from its ongoing drilling at the Excelsior Gold-Silver Project in Nevada, extending mineralisation along the Buster Trend and validating its Carlin Type deposit model.
- New wide, shallow gold intercepts expand Buster Trend mineralisation
- Drilling confirms continuity and open extensions down-dip and along strike
- Imperial Project acquisition advances with permitting and exploration
- Blue Dick prospect sampling underway to define drill targets
- Results reinforce Carlin Type deposit model and district-scale potential
Expanding the Footprint at Buster Trend
Mammoth Minerals Limited (ASX:M79) has released encouraging assay results from its ongoing reverse circulation (RC) drilling program at the Excelsior Gold-Silver Project in Nevada, USA. The latest data reveal multiple wide and shallow gold intercepts along the 7-kilometre-long Buster Gold Trend, a key zone within the project. Notably, a new mineralised area was identified 100 metres west of previous drilling, with an intercept of 13.72 metres at 1.15 grams per tonne gold from 62.5 metres depth, signalling an expanding mineralised footprint.
Additional significant intercepts include a 7.62-metre section grading 2.1 grams per tonne gold from 219.5 metres, extending mineralisation over 100 metres down-dip and remaining open at depth. Other broad zones near surface, such as 33.54 metres at 1.25 grams per tonne gold, further underscore the potential scale of the deposit.
Validating the Carlin Type Deposit Model
The results support Mammoth’s geological model that the Excelsior mineralisation is consistent with a Carlin Type gold deposit, characterised by gold hosted in highly altered limestone sequences with structural controls such as faults and breccias. The presence of high-grade “feeder” zones and broad, shallow mineralised intervals aligns with expectations for this deposit style, which is prolific in Nevada’s Walker Lane trend.
Managing Director Glenn Poole emphasised the significance of these findings, noting that the drilling has validated the deposit model and highlighted open extensions both along strike and at depth. The accelerated assay turnaround has enabled the company to dynamically plan follow-up drilling to test these new targets.
Advancing the Imperial Project and Blue Dick Prospect
Beyond the Buster Trend, Mammoth is progressing exploration at the recently acquired Imperial Project, where permitting is underway to drill advanced targets. Historical underground workings and high-grade sampling indicate a compelling opportunity to add to the mineral inventory with relatively low exploration risk. Significant historic intercepts, including 12.19 metres at 4.74 grams per tonne gold, provide a strong foundation for further drilling.
Meanwhile, surface sampling and mapping campaigns at the Blue Dick prospect are advancing to delineate the extent of gold and silver-rich polymetallic mineralisation. The company aims to bring these trends to drill-ready status later this year, potentially broadening its district-scale footprint.
Strategic Positioning in a Tier-One Gold District
Mammoth’s portfolio in Nevada, including the Excelsior Springs Project and the Imperial acquisition, positions it well within the prolific Walker Lane tectonic zone, a region that has produced over 20 million ounces of gold historically. The company’s systematic approach to drilling, combined with modern assay techniques and detailed geological modelling, is designed to unlock the full potential of these Carlin Type deposits.
While the true widths of mineralisation are yet to be confirmed and drilling continues, the expanding footprint and consistent grades provide a strong signal of resource growth potential. Mammoth’s ongoing exploration and assay results will be closely watched by investors seeking exposure to high-quality gold assets in a stable jurisdiction.
Bottom Line?
Mammoth Minerals’ latest drilling success at Excelsior underscores a growing gold footprint with promising extensions to explore.
Questions in the middle?
- How will upcoming drilling refine the true width and grade continuity of the Buster Trend mineralisation?
- What impact will the Imperial Project acquisition have on Mammoth’s overall resource and development timeline?
- Can the Blue Dick prospect deliver significant polymetallic mineralisation to complement the gold focus?
