Solitario Exploration & Royalty Corp. (“Solitario;” NYSE MKT:XPL; TSX: SLR) is pleased to provide an update on its Pedra Branca platinum-palladium project in Brazil and its Pachuca Norte silver-gold project in Mexico.

Pedra Branca Platinum-Palladium Project, Brazil

Solitario’s joint venture partner, Anglo Platinum Ltd., has initiated a core drilling campaign on the Pedra Branca Project in northeastern Brazil. Anglo Platinum, manager of the project, is planning to complete up to 6,000 meters of core drilling on several magnetic geophysical targets. Anglo Platinum identified these new magnetic targets as a result of a regional airborne magnetic survey they conducted in 2013.

The Pedra Branca project is held through a joint venture with Anglo Platinum controlling 51% and Solitario 49%. Anglo Platinum is providing 100% of the funding for the 2014 drilling program. Over 300 core holes have been drilled on the property to date. Initial results from the drilling program are not expected for at least a couple of months.

Pachuca Norte Silver-Gold Project, Mexico

Solitario’s joint venture partner on its Pachuca Norte silver-gold project in central Mexico, Hochschild Mining plc, has notified Solitario that they have elected to terminate their option to earn an interest in the project. Hochschild recently completed an 18-hole core drilling program totaling 5,573 meters. Highlights of this drilling program (intercepts grading better than 100 grams per tonne silver equivalent, or better) are presented in the table below.

* True width has not been calculated for each individual intercept, but true width is generally estimated at 60%-75% of drilled width;

** Silver Equivalent (AuEq) was calculated using a Ag:Au ratio of 60:1

Solitario will review the results of this program, as well as previously generated data, and decide whether to continue independent exploration, seek a new joint venture partner, or reduce its land holding in the project. Drill hole information contained within this release is reported under Hochschild’s quality control program reviewed by Mr. Walt Hunt, COO for Solitario Exploration & Royalty Corp., who is a qualified person as defined by National Instrument 43-101.
