American Pacific reports additional assay results from 2023 drilling

American Pacific Mining Corp. has reported further assay results from the 2023 resource definition and geotechnical drilling programme at the Palmer Project.

Palmer is an advanced-stage, high-grade volcanogenic massive sulphide-sulphate deposit located in the Porcupine Mining District of the Haines Borough, Alaska, US. Constantine North Inc., a subsidiary of American Pacific, is the operator for the Project and the US$25.5 million 2023 programme has been funded by joint venture partner Dowa Metals & Mining Co., Ltd.

Assay results released herein are from five drill holes targeting the Southwall Zone of the Palmer Deposit and one geotechnical drillhole located in the RW Zone. The five resource definition drillholes within the Southwall Zone 1 continue to return thick intercepts of significant copper and zinc mineralisation. As with the initial drillholes, there are mineralised intervals extending beyond the current mineral resource model, highlighting the potential for a broader mineralised envelope.

Highlights include:

  • 30.7 m of 2.59% Cu and 11.21% Zn, including 6.53% Cu over 2.9 m (CMR23-162B).
  • 39.1 m of 1.44 % Cu, 5.87 % Zn and 25% barite (CMR23-165).
  • 18.4 m of 1.61% Cu and 14.7 m of 2.66% Cu and 2.93% Zn (CMR23-161).

The 2023 assay results to-date have exceeded expectations in Southwall Zone 1, the current resource model is well supported by the infill drill intercepts and initial interpretations also suggest the potential for additional lenses below the model and potential extensions to the northeast and downdip of Zone 1.

The company has also reported significant assay results from a geotechnical drillhole (GT23-024) that intersected 10.8 m of 1.28% Cu, 13.13% Zn and 110.25 g/t silver in the RW Oxide Zone, which is not included in the current Palmer Deposit mineral resource estimate. The GT23-024 intercept is located approximately 100 m from the known MRE and the company looks forward to receiving assay results from the other geotechnical holes drilled from the UM pad to better assess the mineralisation potential in this area.

“We have received approximately half of the assays from this year’s programme and we are very pleased with the Southwall Zone 1 extensions and significant Cu-Zn-Ag mineralisation encountered in the RW Oxide Zone with one of our geotechnical drillholes,” stated Warwick Smith, CEO of American Pacific. “This year’s work, led by Peter Mercer, has established a solid foundation and technical vision for resource expansion and de-risking the Project. We look forward to more assay results later this year and our continued collaboration with Dowa Metals and Mining in 2024.”
