Solitario Exploration & Royalty said Wednesday it will initiate a NI-43-101 preliminary economic study on its Bongara zinc project in northern Peru. This will be the first evaluation to estimate the potential economics of the Bongara project.

Work to date has demonstrated that Bongara has a high-grade zinc deposit with an average resource grade in excess of 12% zinc equivalent, has a relatively large resource base with excellent expansion potential, and produces a clean high-grade concentrate. The project is 39%-owned by Solitario and 61%-owned by Lima-based Compania Minera Milpo.
