Castle Mountain Mining Plans to Release a NI 43-101 Resource Estimate in November

TORONTO, ONTARIO--(Marketwired - Nov 12, 2013) - Castle Mountain Mining Company Ltd. (TSX VENTURE:CMM) ("Castle Mountain Mining", "we", "our" or the "Company") is pleased to announce that the Company now expects to publicly release a National Instrument 43-101 compliant resource estimate being prepared by RPA Inc. ("RPA") by the end of November 2013. Since the spring of 2013 RPA has worked closely with the technical staff of Castle Mountain Mining as we prepared and executed on our Phase 1 drill program and as we investigated the large historic data base created by the previous operator of the Castle Mountain heap leach mine. Historic drilling from the mid 1980's to 1997 consisted of 1,762 holes representing 361,487 metres of dominantly reverse circulation (RC) drilling. Our Phase 1 program of 8,368 metres in 30 RC and core holes together with other testing, sampling and computer modeling contributed to the validation of the historic data and is allowing for preparation of an initial NI 43-101 resource estimate to be released later this month. Within 45 days of the release of this initial NI 43-101 resource estimate the corresponding technical report being prepared by RPA will be filed on SEDAR.

Gordon McCreary, President and CEO, stated, "The publication of an initial NI 43-101 resource estimate for our Castle Mountain property will be an important step in the geologic de-risking of our project. The fact that we already have the key mining permit and have recently had it extended by five years to December 31, 2025 has been another important de-risking step. The low level of technical risk inherent in our project is further accentuated by the fact that the historic heap leach operation produced 1.24 million ounces of gold during 10 years of mining and several years of residual leaching with an excellent metallurgical gold recovery exceeding 80%."

About Castle Mountain Mining Company

Subject to certain obligations, Castle Mountain has 100% of the right, title and beneficial interest in and to the Castle Mountain Venture, a California general partnership, which owns the Castle Mountain property in San Bernardino County, California. The Castle Mountain heap leach gold mine produced over one million ounces of gold from 1992 to 2001, when mining was suspended due to low gold prices.

The Castle Mountain venture land holdings (7,458 acres total) include patented claims (1,298 acres), and unpatented claims (3,209 acres), covering approximately 4,507 acres, plus additional leased claims of approximately 2,951 acres. In June 2013 the Company completed the Phase 1 drill program which tested several exploration targets at various locations on the property. These drill results were disclosed in press releases dated June 20, 2013 and July 16, 2013 and are available at the Company's website at www.castlemountainmining.com. Upon completion of analysis of the Phase 1 program with the aid of computer generated models and the publication of our maiden NI 43-101 resource estimate prepared by RPA, Castle Mountain Mining expects to start a Phase 2 program at the property in early 2014, subject to financing. Castle Mountain Mining has engaged RPA to work with the Company in developing a program that will, amongst other things, identify optimal drill locations, meet and exceed QA/QC standards, and allow the historic drilling on the property made up of 361,487 m of drilling across 1,762 drill holes to be used together with recent drilling to create a mineral resource on the property that is in accordance with NI 43-101.

Castle Mountain Mining Company Ltd., through its wholly owned subsidiaries including Castle Mountain Venture, is focused on the exploration and, if warranted, development of deposits in San Bernardino County, California. The principal gold mineralization identified to date within the Project are below and surrounding the historically mined Pits on the Property including the Oro Belle-Hart Tunnel, Jumbo, and Lesley Anne-Jumbo South Pits, as well as in the South Domes area. Historic (non-compliant to NI 43-101) mineral resources for the project were outlined in a technical report entitled "NI 43-101 REPORT ON THE CASTLE MOUNTAIN PROPERTY, SAN BERNARDINO COUNTY, CALIFORNIA USA" by Thomas Temkin, CPG, dated October 24, 2012 which is available on SEDAR at www.sedar.com.
