Summary
American Tungsten & Antimony Ltd reported significant progress from their Phase 1 diamond drilling programme at the Little Emma Prospect, part of the Antimony Canyon Project in Utah, USA. This drilling has extended the high-grade mineralised areas and confirmed the presence of a large hydrothermal antimony system. The mineralisation is found within the 'Salt and Pepper' calcareous unit, and is characterised by high-grade stibnite pods within a broader envelope. Notable results include intersections such as 10.37 meters at 3.98% antimony, pointing to the system's potential for further expansion. The project is still in early exploration phases, with the potential quantity and grade of resources yet to be fully determined.
Key Points
  • Phase 1 diamond drilling at the Little Emma Prospect in the Antimony Canyon Project has significantly extended the known high-grade mineralised envelope.
  • The drilling programme confirmed a district-scale hydrothermal antimony system with multiple high-grade replacement pod centres.
  • High-grade intercepts include results like 10.37m at 3.98% Sb, including 4.57m at 8.56% Sb.
  • The mineralisation is hosted within the 'Salt and Pepper' calcareous and crystal-rich volcanosedimentary tuff unit.
  • American Tungsten & Antimony Ltd's exploration efforts have identified a stratabound stibnite system with high-grade pods within a broader mineralised envelope.
  • Results show the system is open in multiple directions, indicating potential for further extensions.
  • The Antimony Canyon Project is compared to the Xikuangshan Antimony District, suggesting a large and long-lived mineralising system.
  • The project is still in the early stages of exploration and requires further drilling to estimate a Mineral Resource.
