Solitario Exploration & Royalty Corp. (NYSE MKT:XPL; TSX:SLR) ("Solitario") and Zazu Metals Corporation (TSXV:ZAZ) ("Zazu") are pleased to announce that they have entered into a definitive arrangement agreement (the "Arrangement Agreement") pursuant to which Solitario has agreed to acquire all of the issued and outstanding common shares of Zazu (the "Zazu Shares") by way of a statutory plan of arrangement (the "Arrangement") under the Canada Business Corporations Act.

Highlights of the Combined Company

  • Creation of a leading zinc focused explorer and developer during a time of encouraging supply and demand fundamentals
  • Significant joint venture interests in two large, high-grade zinc development projects with world-class partners:
    • Solitario’s Bongará project in Northern Peru is a high-grade development asset held jointly with Compañía Minera Milpo ("Milpo"), one of the largest zinc producers in Peru
    • Zazu’s Lik project represents a large-tonnage, high-grade and potentially open-pittable development project in Alaska in partnership with Teck Resources Limited ("Teck")
  • Additional portfolio of high quality exploration properties and royalties in the Americas
  • Well-financed, with approximately US$16.5 million in cash and cash equivalents
  • Experienced management team with a track-record of creating value for shareholders by moving assets through feasibility and permitting
  • Enhanced capital markets profile and trading liquidity in combination with strong shareholder support

Chris Herald, Chief Executive Officer of Solitario, stated: “We are very pleased to announce this exciting opportunity that will create value for both Solitario and Zazu shareholders. Since the sale of the Mt. Hamilton project in 2015, Solitario has remained extremely disciplined in its evaluation of growth initiatives while preserving a robust balance sheet and tight capital structure. We are confident that we have both the technical and financial capabilities to significantly increase the value of Zazu’s Lik project by moving the asset through feasibility and permitting. We look forward to working with Zazu’s world-class joint venture partner Teck to pursue a development path beneficial to all parties.”

Gil Atzmon, Founder, Chairman and Chief Executive Officer of Zazu, stated: “This combination represents a unique opportunity to create a leading zinc development company with two high quality assets in the Americas. Zazu shareholders will benefit from increased diversification and access to capital, while importantly maintaining a focus on high-grade resources. We see significant potential in Solitario’s asset base and believe the combined company will be well positioned to take advantage of increased interest in zinc.”

The board of directors of Zazu has unanimously approved the Arrangement and will recommend that Zazu Shareholders vote in favour of the Arrangement.

In addition, Zazu and Solitario have each agreed to pay a termination fee in the amount of US$0.75 million to the other party upon the occurrence of certain termination events.

Convertible Debenture Financing

Concurrent with the signing of the Arrangement Agreement, Solitario will provide Zazu interim debt financing through a secured convertible debenture issued by Zazu in the principal amount of US$1.5 million (the "Debenture"). The Debenture is secured by way of a general security and pledge agreement and bears interest at a rate of 5% per annum. If the Arrangement Agreement is terminated prior to the effective date of the Arrangement, all principal amounts outstanding and any interest payable thereon will become payable two years following the issuance of the Debenture.
