VANCOUVER, British Columbia, Nov. 22, 2022 (GLOBE NEWSWIRE) — American Pacific Mining Corp (CSE: USGD / OTCQX: USGDF / FSE: 1QC) (“American Pacific” or the “Company”) is pleased to announce the results of the analysis of the Madison copper-gold project (“madison” or the “Project‘) performed by a skarn expert on behalf of operating partner Rio Tinto who identified the presence of a major new target area expected to be the focus of exploration and drilling in 2023.

report conclusions

  • The skarn portion of the mineralized footprint is a robust zone up to 130 meters thick, comparable to other skarn deposits known around the world.

  • The richness of limestone, dolomite and other calcareous units in the area favors the formation of skarn deposits.

  • The mapped (favorable) carbonates in the area measure approximately 2,100 meters by 650 meters and offer significant potential for additional mineralization within the project area.

  • Thrust rocks, while not conducive to skarn mineralization, can concentrate ore-bearing fluids in favorable rocks by acting as an impermeable cap while hiding additional potential skarn deposits distal to the exposed mineralization.

  • It is also recommended that distal areas where no/limited drilling have previously been performed should be systematically tested.

“The recommendation of the skarn expert is that Kennecott Exploration (the exploration division of Rio Tinto Group) continues to explore for mineralization in the carbonate rocks known to host the skarns. In addition, he suggests that surface mineralization such as copper-rich gossans may exist as products of erosion of shallower orebodies,” said President Eric Saderholm. “Testing these new areas could expand mineralization in areas that have never been drilled. We believe this recommendation will mean that Rio Tinto will continue to actively explore Madison as part of its joint venture commitments.”

The large and well exposed Rader Creek Pluton, measuring approximately 16 by 6.5 kilometers and having at least 2,100 meters of exposed contact with the favorable carbonate sequence, is the probable cause of the skarn mineralization. This long contact has seen little exploration beyond historically drilled holes near the existing mine (see Figure 2).

The shallower mineralization has experienced some level of erosion, exposing the known skarns and allowing earlier mining of the localized surface and near-surface outcrops. Exotic deposits such as copper-rich ferricretes (cemented, iron-rich material indicative of an eroding skarn) may exist in many areas of shallow erosion. These deposits are abundant at Madison with little to no exploration drilling.

The lower temperature retrograde alteration consists of quartz, calcite, chlorite, pyrrhotite, pyrite, chalcopyrite (copper mineral), gold and trace amounts of both sphalerite (zinc mineral) and galena. This low temperature phase is generally associated with the deposition of degradable metals such as gold, copper, zinc and lead.
