Early Drilling Success Raises Stakes for Antimony Resource at Utah Project
American Tungsten & Antimony Ltd has reported substantial stibnite mineralisation in the first two holes of its maiden drilling campaign at the Antimony Canyon Project in Utah, validating its geological model and setting the stage for further exploration.
- First two diamond drill holes intersect massive to disseminated stibnite
- Hole 001 reveals a 42m mineralised zone with a 19m thick main horizon
- Hole 002 shows higher intensity mineralisation with arsenic sulphides
- Hole 003 drilling targets a major feeder structure at ~500 ft depth
- Assay results pending; further drilling and NOI submissions planned
Early Drilling Success at Antimony Canyon
American Tungsten & Antimony Ltd (ASX, AT4) has kicked off its maiden diamond drilling programme at the Antimony Canyon Project in Utah with promising early results. The company’s initial two holes, drilled on its 100% owned Patented Claims, have intersected significant zones of mineralisation dominated by stibnite, the primary antimony sulphide mineral. This early success is a strong validation of the company’s extensive preparatory work, including geophysics and surface sampling, which guided the targeting of the Emma Claim; a historically mined area within the project.
Substantial Mineralised Zones Confirmed
Hole ACP26DD001 intersected a broad 42-metre mineralised zone, including a 19-metre thick main horizon of massive to semi-massive stibnite. Hole ACP26DD002, while still being processed, reportedly encountered even more intense mineralisation, along with minor occurrences of orpiment and realgar; arsenic sulphides that often serve as pathfinder minerals for high-grade antimony and gold systems. These findings suggest the drilling is approaching a significant hydrothermal system, with alteration intensity increasing to the east, consistent with the company’s geological model.
Targeting the Feeder Structure
Drilling is currently underway on Hole ACP26DD003, designed to intersect the interpreted feeder structure at approximately 500 feet depth. Early visual inspection of the core reveals stronger zones of orpiment and realgar, alongside thick sulphide intercepts, which could indicate proximity to the heat source driving mineralisation. This hole is being drilled at a shallower angle (-45 degrees) to optimally cut across the vertical feeder, differing from the steep dips of the first two holes.
Next Steps and Broader Exploration Plans
American Tungsten is expediting assay analysis for all three holes to quantify the mineral grades and validate visual estimates. The company also plans to submit Notices of Intent (NOIs) for drilling at other historical workings within its patented claims, including the Pluto, Star, and Emily prospects. With over twenty historical workings across the claim area, the company aims to build a pipeline of drill-ready targets to fully unlock the district’s potential.
Strategic Positioning in Critical Minerals
The Antimony Canyon Project is one of the largest and highest-grade undeveloped antimony systems in the United States. American Tungsten’s secure land tenure through patented claims and streamlined permitting positions it well to advance critical mineral development in a Tier-1 jurisdiction. The company’s broader strategy includes vertical integration and supplying conflict-free critical minerals to Western economies, with additional projects such as the Tennessee Mountain Tungsten Project in Nevada complementing its portfolio.
Bottom Line?
With visual mineralisation confirmed and feeder drilling underway, American Tungsten is poised to define a significant antimony resource in Utah.
Questions in the middle?
- What will the pending assay results reveal about the grade and economic potential?
- How extensive is the feeder structure and what size resource might it support?
- What timeline and capital will be required to advance from exploration to development?
