American Pacific Mining to Acquire Constantine Metal Resources

American Pacific Mining Corp (CSE: USGD FWB: 1QC OTCQX: USGDF) (" APM ") and Constantine Metal Resources Ltd . (" Constantine ") ( TSXV: CEMOTCQX:CNSNF ) announce that they have entered into a definitive agreement (the " Definitive Agreement ") pursuant to which APM will acquire all of the issued and outstanding common shares of Constantine (the " Transaction ") in an all-share transaction, providing Constantine shareholders with an immediate upfront premium of 48.6% based on each company's respective 20-day volume weighted average price ( "VWAP" ).

The combined company will be a premier exploration and development company in the western USA with two projects being aggressively advanced under strategic partnerships with well-respected major metal producers and an expanded portfolio of prospective precious and base metals assets.

Highlights of the Transaction and Strategic Rationale:

• Shareholders of the combined company will gain exposure to two advanced exploration projects under strategic partnerships with majors:
  • Palmer (Constantine) is an attractive PEA-stage (US$266 million after-tax NPV at 7% discount rate) ¹ zinc-copper-gold-silver volcanic massive sulfide (VMS) project located in a strategic area of Southeast Alaska, being advanced with world-class joint-venture (" JV ") partner Dowa Metals & Mining Co., Ltd. of Japan (" Dowa "). The JV approved 2022 program and budget is US$18 million, with funds being advanced exclusively by Dowa, as required, during project advancement. Constantine has an option to contribute pro-rata, up to December 31 ^st , 2022, to maintain Constantine's 44.91% interest.
  • Madison (APM) is a past-producing high-grade copper-gold skarn and porphyry system located in the heart of Montana's prolific copper-gold belt under an earn-in joint-venture agreement, whereby Kennecott Exploration Company, part of the Rio Tinto Group, may spend US$30 million to earn a 70% interest.
• The combined company will be well financed with a pro-forma cash balance exceeding C$10 million allowing APM to aggressively progress projects while leveraging spending commitments of partners.
  
• Improved capital markets profile with increased market capitalization exceeding C$85 million and better positioned to attract additional institutional and high net-worth investors.
• The Transaction has strong shareholder support, with Constantine's two largest shareholders Michael Gentile and John Tognetti and management and directors of Constantine, together representing 27% of the issued and outstanding common shares of Constantine, entering into voting support agreements with APM.
• Strong and experienced management team (APM was recently nominated for five awards at the S&P Global Platts Metals Awards) with demonstrated ability to raise capital and operate in the western USA.
• APM and Constantine shareholders will have exposure to expanded portfolio of precious and base metals exploration projects in Idaho, Nevada and Arizona.

CEO of American Pacific Mining, Warwick Smith, stated: "This is a transformational step for American Pacific as the Palmer Project gives us an established PEA-stage asset with a tremendous amount of exploration upside. We are very impressed with the quality of technical work completed by Constantine and Dowa to-date and look forward to collaborating with our new partners and stakeholders to expand resources and realize the full potential of this high-grade VMS system while continuing to deliver exposure to progress and new discoveries across our existing portfolio of highly prospective past-producing exploration projects."

CEO of Constantine Metal Resources, Garfield MacVeigh, commented: "Constantine is pleased to enter into this agreement and our Board unanimously recommends the transaction to shareholders at a significant market premium. We believe American Pacific's focus, financing capabilities and breadth of exploration experience in the US will result in Palmer reaching its full potential. We would like to thank our shareholders, the team at Constantine, our Board and our joint venture partner at Palmer, Dowa, for all their support."

The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that PEA results will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
