Solitario Announces Milpo / Votorantim Have Earned a 61% Interest in Its Bongará Zinc Project, Peru

Solitario Exploration & Royalty Corp. (“Solitario;†NYSE MKT: XPL; TSX: SLR) is pleased to announce that Votorantim Metais (“Votorantimâ€) and its successor in interest, Compañía Minera Milpo S.A.A. (“Milpoâ€; Lima Stock Exchange: MILPOCI) have earned a 61% interest in Solitario’s Bongará Zinc Project in Peru. Votorantim completed all the conditions necessary to earn its interest and Solitario now holds a 39% interest in the project. As previously announced (November 13, 2014), Votorantim and Milpo entered into an agreement for Milpo to buy Votorantim’s interest in the Bongará project and Milpo’s Board of Directors approved the purchase in the fourth quarter of 2014. Milpo is 51% owned by Votorantim with the remaining 49% of Milpo publicly owned.

Milpo is the second largest zinc producer in Peru, operating three of the largest underground zinc mines in Peru. In addition to its strong cash-flow positive zinc production in Peru, Milpo reported cash on its balance sheet of US$436 million at the end of 2014. Votorantim is the world's fifth largest primary zinc producer with three operating zinc smelters, two operating zinc mines, and also has operations in the United States and China. It owns the Cajamarquilla zinc smelter and is the majority shareholder of Milpo, both located in Peru. From the second half of 2006 to the end of 2014, Votorantim has expended approximately US$42.4 million on exploration and development at Bongará.

2015 Work Program

Milpo has assumed operatorship of the project from Votorantim and has informed Solitario that it intends to complete a pre-feasibility study on the Bongará project by the end of 2015. This work will be instrumental in providing an initial analysis of project economics and guide the direction of feasibility work slated for 2016. In addition, Milpo plans to complete the access road to the project during 2015. To date, approximately 25 kilometers of the road have been completed with about six more kilometers required. Completion of the access road will allow acceleration of development activities and lower costs, as access has been exclusively by helicopter or footpaths to date. Additional 2015 work plans are being evaluated by Milpo.

About the Project

Zinc mineralization occurs as a Mississippi Valley Type (“MVTâ€) deposit and is contained in carbonate rocks of the Pucará rock formation, the host-rock for many of Peru’s zinc mines. Peru is the third largest zinc producing country in the world. Solitario released its initial NI 43-101 compliant resource estimate for the project on June 23, 2014. The Bongará resource estimate was based on a database that includes drilling campaigns of two different companies. A total of 82 drill holes were completed by Cominco totaling 24,781 meters drilled from 1997 to 2000, and 404 drill holes completed by Votorantim including 92,499 meters drilled from 2006 to 2013.

Terms of the Bongará Joint Venture with Votorantim Metais

Currently, Solitario owns 39% of the Bongará project and Milpo/Votorantim owns 61%. Since inception of the joint venture in 2006, Votorantim has funded 100% of project expenditures. Milpo will earn a 70% interest in the project by continuing to fund all project expenditures and committing to place the project into production based upon a positive feasibility study. After earning 70%, 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.
