Milpo to Participate in the Preparation and Funding of the Bongará Preliminary Economic Assessment

DENVER--()--Solitario Exploration & Royalty Corp. (“Solitario;” NYSE MKT: XPL; TSX: SLR) is pleased to announce that its joint venture partner, Minera Milpo (“Milpo”), has elected to participate in the development and funding of a Preliminary Economic Assessment (“PEA”) on the Bongará high-grade zinc deposit in northern Peru. Completion of the PEA is expected by the end of the second quarter 2017. Currently, Solitario owns 39% of the Bongará project and Milpo owns 61%.

In January 2017, Solitario engaged SRK Consulting (U.S.), Inc. (“SRK”), an independent and internationally recognized mining engineering firm, to complete a PEA for the Bongará project. Chris Herald, President and CEO of Solitario, stated, “We are delighted that Milpo will collaborate on Bongará’s maiden PEA. We believe that Milpo’s support and operational experience in Peru will strengthen the technical aspects of the study. We are excited about Bongará’s economic potential and look forward to the completion of this report.”

A total of 486 core holes (117,280 meters) have been drilled on the project. Work to date has demonstrated that Bongará is a high-grade zinc deposit with an average resource grade in excess of 12% zinc equivalent. The project has a relatively large resource base with excellent expansion potential, and produces a clean high-grade zinc sulfide concentrate. SRK previously prepared a NI 43-101 Technical Report on Resources for the Bongará Project in 2014.

This release has been reviewed for accuracy by Walter Hunt, Chief Operating Officer of Solitario, a “qualified person” as that term is defined in NI 43-101.

Terms of the Bongará Joint Venture

Since inception of the Bongará joint venture in 2006, the Brazilian conglomerate Votorantim and its subsidiary, Milpo, have funded 100% of project expenditures. Milpo can earn a 70% interest in the project by continuing to fund all project expenditures (except this PEA, which is 50%/50% funded by Solitario and Milpo and does not alter any of the terms of the joint venture) and committing to place the project into production based upon a positive feasibility study. After earning 70%, and at the request of Solitario, Milpo has further agreed to finance Solitario’s 30% participating interest for construction. Solitario will repay the loan facility through 50% of its net cash flow distributions.
