American West Metals Limited (American West or the Company) (ASX: AW1) is pleased to announce the assay results for the third diamond drill hole completed at the West Desert Project in Utah (West Desert or the Project).

  • A very wide intercept of zinc, copper, gold and indium mineralisation has been intersected near surface in metallurgical drill hole WD22-02, the third drill to be completed by American West at the West Desert Project
  • Assays confirm a thick high-grade interval from 74.54m:
    • 11.44m @ 6.46% Zn, 0.17% Cu, 0.22g/t Au, 90.73g/t In from 74.54.m, including;
      • 7.17m @ 8.57% Zn, 0.26% Cu, 0.33g/t Au, 77.48g/t In from 74.54m
  • The high-grade interval is located within a wider zone of 35.52m @ 3.2% Zn, 0.17% Cu, 0.15g/t Au, 16.43g/t Ag and 52.66g/t In from 74.54m
  • The assays will be used for metallurgical test work and resource estimation for a potential openpit mining scenario
  • Diamond drilling continues at West Desert with more assay results expected in the comingweeks

Drill hole WD22-02 was designed for metallurgical testing of the near surface ore lenses and was drilled to a downhole depth of 233.8m.

WD22-02 intersected a very thick interval of zinc, copper, gold and indium mineralisation beginning at approximately 60 vertical metres from surface. The mineralisation is variably weathered and consists of oxide and transitional classified ores. The drill hole confirms the continuity near surface of the Main Zone of the West Desert Deposit and is supportive of the potential for an open pit development scenario.

Historical metallurgical test work on the oxidised zinc and copper mineralisation has produced highly encouraging results with traditional processing methods and with high recoveries of zinc, copper and indium from this near surface mineralisation.

Dave O’Neill, Managing Director of American West Metals commented:

“We are very pleased to receive strong assay results for WD22-02, and these will used to support the metallurgical program.

“The drill hole has intersected thick zinc, copper and indium mineralisation near surface. The interval is particularly enriched in Indium, a critical metal and important credit within our zinc concentrate, with grades up to 237g/t In.

“The drill hole confirms the upper extensions of very thick mineralisation encountered in the first two drill holes completed by American West, and highlights the potential for an open pit operation.

“We are looking forward to reporting on the results for the remaining drill holes in the coming weeks.”
