American West Metals Limited (American West or the Company) (ASX: AW1) is pleased to announce the completion of diamond drill holes WD22-04 and WD22-05 at the West Desert Project in Utah (West Desert or the Project).

  • Drill holes WD22-04 and WD22-05 have been successfully completed at the West Desert Project
  • WD22-04: over 400m of mineralisation visually logged including:
    • Multiple thick intervals of copper sulphide dominant porphyry and intrusive hosted mineralisation
    • 25m of strong to semi-massive copper and zinc sulphides in skarn from 420m
    • 45m of strong zinc and copper sulphides in massive skarn from 572m
    • 137m of continuous molybdenum rich mineralisation from 618m
  • WD22-05: a total of 230m of zinc and copper mineralisation visually logged over multiple intervals including:
    • 45m of strong zinc sulphides in skarn from 180m
    • 54m of strong zinc and copper sulphides, with potential coarse gold, in massive skarn from 294m
    • 15m of very strong zinc and copper sulphides, including bornite, from 350m
    • Three thick lenses of CRD mineralisation from 613m, including bands of semi-massive zinc sulphides from 661m
  • Drilling results continue to extend and confirm the continuity of the known mineralisation of the West Desert Deposit
  • Exploration drilling has commenced targeting high priority near-mine targets
  • Assays for the outstanding drill holes are pending and due in the coming weeks

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

“The drilling is continuing to produce amazing results. The last two drill holes, WD22-04 and WD22-05 were important for resource definition and expansion and certainly appear to have delivered for us.

“Both drill holes have hit thick intervals of mineralisation, and importantly, confirmed our assumptions and geological models.

“These two drill holes complete the resource definition phase of the drilling program and have continued to highlight the quality and scale of the West Desert Deposit.

“We are excited to now begin the exploration phase of the drilling to test a number of high-quality targets in the near mine area.

“We look forward to reporting on these results and the assays from the completed drilling in the coming weeks.”


WD22-04 is the fifth drill hole of American West’s drill program, and was designed to extend the strong copper mineralisation located on the porphyry/skarn contact further out to east. Historical drill holes in this location have intersected high-grade semi-massive chalcopyrite (including 13.4m @ 2.7% Cu from in drill hole CC-39) and a number of these zones remain open.

WD22-04 was drilled oblique to the main trend of drilling to utilize a fully permitted drill pad that was located on private land (100% owned by AW1). The hole was drilled to a depth of 754.8m and encountered over 400m metres of visual mineralisation (Figure 2 & Table 2). Intersections are expressed as downhole widths and are interpreted to be close to true widths.

Drill hole WD22-04 has confirmed the continuation of copper mineralisation along the prospective porphyry/sediment contact. Numerous thick zones of chalcopyrite rich mineralisation were encountered within the main porphyry stock (disseminated and vein hosted) and the contact related magnetite skarn. Strong sphalerite was also present in the more massive magnetite skarns.
