Solitario Signs Letter of Intent with Hochschild Mining on Its Pachuca Norte Silver-Gold Project, Mexico12:32 EST Thursday, March 07, 2013 DENVER (Business Wire) -- Solitario Exploration & Royalty Corp. (“Solitario;” NYSE MKT: XPL;TSX: SLR) is pleased to announce that it has signed a binding Letter of Intent (“LOI”) with Minera Hochschild México S.A. de C.V., a 100%-owned subsidiary of Hochschild Mining plc (LSE: HOCM.L / HOC LN) ("Hochschild"), on Solitario's Pachuca Norte silver-gold project in central Mexico. Solitario's 100%-owned Pachuca Norte project (formerly called “Pachuca Real”), encompasses approximately 19,000 hectares of mineral rights in and around the famed Pachuca silver-gold mining district. Historic production from the Pachuca district totals approximately 1.4 billion ounces of silver and over 7.0 million ounces of gold, making it one of the largest silver-gold districts in the world. A map of the project area can be viewed on Solitario's website at http://www.solitarioxr.com/art/PachucaNorte.pdf. Terms of the Venture Agreement Per the terms of the binding LOI, Hochschild can earn a 51% interest in the project by spending a total $10.0 million on exploration over a five-year period. The initial 12-month work program of $1.5 million is a firm commitment. The following table presents the entire five-year work commitment schedule:                       Exploration Expenditures and Due Dates         Amount         Aggregate Amount 12 months from signing - firm commitment         $ 1,500,000         $1,500,000 18 months from signing - optional commitment         $ 500,000         $2,000,000 36 months from signing - optional commitment         $ 3,000,000         $5,000,000 60 months from signing - optional commitment         $ 5,000,000         $10,000,000 Hochschild will have the right to earn an additional 19% (total 70%) by completing a positive feasibility study for the project. Both parties are currently working on drafting and signing a definitive agreement. Upon signing a definitive agreement, expected in approximately 30 days, Hochschild will become project manager, and will have the right to terminate the agreement at any time following its firm initial work commitment. Chris Herald, President and CEO of Solitario, stated, "With Hochschild's long history of exploring for, developing and mining vein deposits, and current successful management of four underground vein mines, we believe they are the perfect partner to advance our high-potential Pachuca Norte silver-gold project in Mexico. Past exploration by our former partners has laid substantial groundwork for Hochschild to move rapidly forward offsetting previously drilled holes that are strongly mineralized as shown in the drill hole table provided below. With this latest agreement with Hochschild, Solitario now has a portfolio of three significant joint venture projects in which our partners are spending well in excess of $12 million on exploration and development work for 2013.” Project History The Pachuca Norte land package encompasses parts of the old Pachuca district, but more importantly, covers the most prospective extensions of the district to the north, northwest, and east. Prior to Solitario's acquisition of the mineral rights, the entire land package had been held by the Mexican government from 1947 to 1990, and then sold to a private Mexican company that controlled the claims until recently. During this 58-year period only a limited amount of exploration was conducted. Shortly after Solitario acquired the majority of its land position in early 2006, it formed a joint venture with Newmont Mining from 2006-2008 and then Buenaventura from 2010-2011. Newmont identified 38 high-quality drill targets consisting of high-grade silver-gold veins that are distributed over a geographic area measuring 20 kilometers long and ten kilometers wide. Newmont drilled 19 holes totaling 7,873 meters. Buenaventura expanded upon Newmont's work and drilled 38 holes totaling 13,489 meters. Hochschild has indicated that its initial 12-month work program will be focused upon testing a number of these already well-defined drill targets. The 15 best drill hole intercepts from 10 separate prospect areas are presented in the table below.
