Castle Mountain Mining Provides Corporate Update

TORONTO, ONTARIO--(Marketwired - July 7, 2014) - Castle Mountain Mining Company Limited ("Castle Mountain" or the "Company" (TSX VENTURE:CMM)): is pleased to provide an update on corporate activities and ongoing development work at the Castle Mountain Mine in San Bernardino County, California.

Following the closing of a bought deal financing for gross proceeds of $5,755,750 on June 27^th, 2014, the Company is now fully financed through completion of a feasibility study, and completion of the current Phase II drill program. The Company expects to release preliminary results of the feasibility study in early Q1, 2015.

President and CEO Gord McCreary commented; "The completion of a feasibility study and a phase two drill program are the next significant development milestones on the path to delivering the Castle Mountain Mine back into production. We are confident that an engineering optimization program, coupled with infill and exploration drilling, will improve upon the already robust results of our Preliminary Economic Assessment. We remain convinced that the Castle Mountain Mine is a best-in-class asset, and look forward to delivering continued positive results and confirmation."

Feasibility Study

The Company is in the process of selecting an engineering firm, and expects to release details of the partnership before the end of July, 2014. The scope of work to be undertaken includes;

• Optimization of the mine plan with a focus on reducing the strip ratio
• Process flow sheets, plant and leach pad designs
• Full hydro-geological study
• Confirmatory metallurgical test program, focused on a combination of material below the pit bottoms and areas anticipated for the first phase of production
• Pit slope evaluation
• Mine support infrastructure: electrical power, water, mine ancillary facilities, access road(s), communication facilities
• Environmental, permitting and mine closure
• Construction plan, Execution plan, EPCM schedule

Phase II Drill Program

The Company has commenced the Phase II drill program, and expects initial assay results in July, 2014. As the mine plan continues to be refined, Castle Mountain will actively target drilling within the pit limits in an effort to reduce the strip ratio and provide a feedback loop with respect to mine planning.

The drill program is expected to be comprised of the following;

• Five PQ (large diameter) core holes in the base of the historic pits, and zones currently targeted for the early stages of production
• PQ core will be assayed and delivered to McClelland Labs Inc. for both bottle-roll and column metallurgical testing
• A drill program of up to 10,000 metres (combined core and reverse circulation) designed to both infill current resources, and define new resources in the planned pit shells

About Castle Mountain Mining Company

Subject to certain obligations, Castle Mountain Mining 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 (6,160 acres). On December 11, 2013, the Company filed the Technical Report for its maiden NI 43-101 mineral resource estimate, that is available both on SEDAR at www.sedar.com and on the Company's website at www.castlemountainmining.com.

Castle Mountain Mining Company Limited, 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.
