TORONTO, ONTARIO--(Marketwired - Dec 4, 2013) - Castle Mountain Mining Company Ltd. (TSX VENTURE:CMM) ("Castle Mountain Mining", "we" or the "Company") is pleased to announce that RPA Inc. ("RPA") has been engaged by the Company to prepare a Preliminary Economic Assessment ("PEA") of the Castle Mountain Gold Project in San Bernadino County, California. RPA was previously engaged to complete the preparation of the Company's Maiden NI 43-101 Mineral Resource Estimate, which was publicly released on November 21^st, 2013 and the Technical Report to be delivered within 45 days of that same press release. The Company expects this PEA to be delivered in the First Quarter of 2014, and also expects to have a significant cash position remaining in the treasury after completion of the PEA.

Gord McCreary, President and CEO stated, "We have elected to undertake a Preliminary Economic Assessment to further de-risk the Castle Mountain Gold Project. Creating economic parameters around the recently defined Mineral Resource Estimate is a critical step in confirming the commercial viability of the project. Given the large scale and high grade of the Mineral Resource Estimate, a mining permit in hand, and a history of production at very low capital and operating costs, we believe the PEA will demonstrate the very high quality of the Castle Mountain Gold Project."
