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. The Company has recently 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, Castle Mountain Mining expects to start a Phase 2 program at the property, subject to financing. Castle Mountain Mining has engaged RPA Inc. 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 354,800 m of drilling across 1,729 drill holes to be used together with recent and future drilling to create a mineral resource on the property that is in accordance with National Instrument 43-101 ("NI 43-101"). The Company anticipates the release of the technical report following the completion of the Phase 2 drill program.

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 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
