Mammoth Minerals Mobilises Drill Rig After Mapping 345m of Blue Dick Mine Workings

Mammoth Minerals has initiated the second phase of exploration at its Excelsior Gold-Silver Project in Nevada, leveraging a pioneering 3D underground survey of the historic Blue Dick Mine to guide upcoming drilling.

  • First-ever 3D underground survey reveals 345m of historical workings at Blue Dick Mine
  • High-grade surface samples include up to 6,630g/t silver and polymetallic mineralisation
  • Blue Dick Mine Trend extends 2.9km, complementing 5km Buster Trend strike length
  • Diamond drill rig mobilised to test extensional potential along Buster Trend
  • Detailed underground mapping and sampling underway to refine drilling targets

Historic Mine Revisited with Modern Technology

Mammoth Minerals Limited (ASX – M79) has embarked on the second phase of exploration at its recently acquired Excelsior Gold-Silver Project in Nevada, USA, following a breakthrough 3D underground survey of the Blue Dick Mine. This pioneering survey, the first of its kind at the site, uncovered 345 metres of historical underground development across two levels, revealing multiple stoping areas that had previously only been documented through surface sampling.

The Blue Dick Mine, dating back to the 1870s, has long been recognized for its high-grade mineralisation, with surface samples reporting exceptional grades of up to 6,630 grams per tonne silver, alongside gold, copper, lead, and antimony. However, until now, no exploration drilling or geophysical surveys had been conducted underground, leaving much of its potential untested.

Strategic Sampling and Drill Planning Underway

Building on the 3D survey insights, Mammoth has commenced detailed underground mapping, channel sampling, and structural measurements to better understand the geometry and extent of the mineralisation. This approach aims to refine drill targets and evaluate the potential for extensions beyond known mineralised zones.

Managing Director Glenn Poole highlighted the significance of the findings, noting the scale of historical workings and the polymetallic nature of the Blue Dick Mine Trend, which extends approximately 2.9 kilometres. This trend complements the adjacent Buster Trend, which boasts a strike length of 5 kilometres and is the focus of the imminent diamond drilling program.

Drilling to Test Promising Extensions

The mobilisation of a diamond drill rig to site marks a critical step in Mammoth’s exploration strategy. The initial drilling will target the Buster Trend, aiming to confirm and expand upon the high-grade mineralisation identified through surface sampling and underground mapping. The combination of these two trends within the Excelsior Project area positions Mammoth to potentially unlock significant new resources in a historically productive mining district.

Beyond Excelsior, Mammoth’s portfolio includes other promising assets across the Americas, such as the Bella Gold Project in South Dakota and the Skyline VMS Copper-Zinc-Silver Project in Newfoundland, underscoring the company’s diversified approach to resource development.

Looking Ahead

As Mammoth advances its exploration program, the market will be watching closely for assay results from channel sampling and drilling. These results will be pivotal in assessing the true scale and economic potential of the Blue Dick and Buster Trends, potentially reshaping the company’s valuation and development roadmap.

Bottom Line?

Mammoth’s integration of modern 3D surveying with targeted drilling could redefine Excelsior’s resource potential; next results will be key.

Questions in the middle?

  • Will the upcoming drilling confirm extensions of high-grade mineralisation along the Buster and Blue Dick Trends?
  • How might the polymetallic nature of the Blue Dick mineralisation impact future project economics?
  • What timeline can investors expect for resource updates and potential development milestones?
