American Pacific reports most significant copper drill intersections yet

Palmer is an advanced-stage, high-grade volcanogenic massive sulfide-sulfate deposit (VMS) located in the Porcupine Mining District of the Haines Borough, Alaska, USA. Constantine North Inc., a subsidiary of American Pacific, is the operator for the Project and the approximately US$20 million 2023 programme was funded by joint venture (JV) partner Dowa Metals & Mining Co., Ltd.

The final batch of 2023 assay results include the four most significant copper (Cu) drill intersections (grade x thickness) reported to-date at Palmer, with significant zinc (Zn), gold (Au) and silver (Ag) results, as well as extending Cu-Zn mineralisation beyond the current mineral resource estimate (MRE).

Highlights include:

• CMR23-172 Zone 1: 43.8 m grading 6.54% Cu, 3.15% Zn, 0.42 g/t Au and 27.97 g/t Ag (8.22% CuEq).
• CMR23-167 Zone 1: 37.1 m grading 4.57% Cu, 8.44% Zn, 0.50 g/t Au and 29.33 g/t Ag (8.40% CuEq).
• CMR23-169 Zone 1: 33.2 m grading 5.48% Cu, 7.22% Zn, 0.64 g/t Au and 36.78 g/t Ag (8.95% CuEq).
• CMR23-171 Zone 1: 23.9 m grading 9.03% Cu, 3.49% Zn, 0.83 g/t Au and 41.75 g/t Ag (11.15% CuEq).
• CMR23-168 Zone 1: 28.4 m grading 2.29% Cu, 4.01% Zn, 0.21 g/t Au and 26.61 g/t Ag (4.20% CuEq).
• CMR23-174 Zone 2-3: 39.8 m grading 1.11% Cu, 4.34% Zn, 0.45 g/t Au and 32.45 g/t Ag (3.31% CuEq), including 17.8 m grading 1.05% Cu, 8.86% Zn, 0.94 g/t Au and 66.24 g/t Ag (5.54% CuEq).

“The final assay results from Palmer’s 2023 resource definition drilling have exceeded expectations with tremendous copper grades and aggregate metals values over significant widths,” commented Peter Mercer, Senior Vice President, Advanced Projects. “Last year’s drilling has extended the mineralised envelope beyond the current MRE and our team is updating our 3D geological model. Preliminary interpretations have highlighted several priority target areas for follow-up drilling in 2024. In addition, the knowledge gained from this year’s drilling will provide valuable insights as we re-evaluate and rank the numerous VMS showings throughout the mineralised district.”

The 2023 diamond drill programme successfully targeted high-priority areas in two unique mineralised lenses, Zone 1 and Zone 2 – 3, which together make up the South Wall Zone of the Palmer deposit. The company is incorporating all 2023 results into its 3D geological model to complete interpretation/analysis and target rank drill locations for the 2024 programme.

The third and final batch of assay results reported in this release consists of 13 drillholes (seven at Zone 1, five at Zone 2 – 3, and one geotechnical drill hole at the RW Oxide Zone).
