American Pacific Mining Corp. has reported results from the final six of eight reverse circulation drill holes completed during Phase I 2025 drilling at the company’s Madison project.
Highlights:
- APMAD25-08 intersected three different mineralised zones, with the upper zone returning 44.1 g/t Au over 1.5 m within a broader interval averaging 10.2 g/t Au over 7.6 m, starting from 189.2 m downhole. The second zone returned 4.5 g/t Au and 0.2% Cu over 3 m, starting from 230.1 m downhole.
- APMAD25-08 was a 175 m step-out to the northwest of the historical Broadway Mine area, with very limited drilling in between, highlighting the expanded exploration search space and emerging link between the Broadway and Madison mines.
- APMMAD25-05 extended the copper mineralised envelope down plunge towards the common vector between the Broadway and Madison mines, with 0.5% Cu over 27.4 m and 0.7 g/t Au over 16.8 m.
- APMMAD25-06 returned significant pathfinder mineralisation, including a notable interval of 3.0 m averaging 0.23% Bi with 14.5 ppm Te and 4.5 m of 159 ppm Bi with 63 ppm Te.
- APMMAD25-07 and 08 returned further porphyry-style geochemical signatures, including assay values of up to 25.8 ppm Bi with 11.9 ppm Te over 1.5 m.
Warwick Smith, CEO of American Pacific, commented: “Our drilling shows a clear link between the historic Madison and Broadway mines, with the best gold interval from the programme highlighting a tremendous opportunity to extend higher grade skarn mineralisation along strike at shallower depths and vector towards the porphyry feeder system we believe is responsible for the higher-grade mineralisation within the skarn. Our next phase of drilling, set to commence during 2H25, will use data collected from Phase I drilling to help refine drill targets as we work towards delineating what our team believes could be a substantial buried porphyry.”
Eric Saderholm, Managing Director of Exploration, added: “The Phase I drill results at Madison validate our current geological model and confirm the historic Broadway and Madison mines are structurally and stratigraphically linked within a broader mineralised corridor. This is a revelation that past exploration efforts did not identify. We are very pleased with the strength of the skarn mineralisation encountered and the porphyry-style geochemical signatures. These include elevated bismuth tellurides and are but one of the lines of evidence that strongly support the presence of a deeper porphyry system. These mineral assemblages are rare in other geologic settings and are significant pathfinder minerals associated with porphyry and high-temperature skarn systems. Their presence supports the interpretation of a robust mineralising system at depth and provides strong vectors for targeting the potential porphyry centre in upcoming drilling phases.”
Phase I results from the project have confirmed additional skarn mineralisation alongside strong geological indicators consistent with a deeper porphyry system, including alteration assemblages, mineral zoning, and geochemical signatures. These findings reinforce the company’s interpretation of a larger mineralised system at depth, with structurally controlled pathways offering critical vectors for targeting. The data has significantly refined future drill planning and prioritised the most prospective zones for deeper porphyry-focused exploration.
Select holes (03, 04) were located to test areas of historic material from past mining operations at the project. APMMAD25-03 returned 0.7 g/t Au, 20.8 g/t Ag and 0.3% Cu over 10.7 m from surface, confirming that a substantial portion of the material retains strongly anomalous metal values. Additional grab samples of stockpiled material (nine total samples) ranged from 0.84 to 45.4 g/t Au, 21.3 to 100 g/t Ag and 0.85 to 8.33% Cu, further demonstrating the potential for material previously considered waste to provide a cash flow opportunity in the future.
