Timmins Gold Corp. Announces Updated Reserve and Resource Estimates for the San Francisco Gold Project

104% Increase in Proven & Probable Reserves over 2010

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 20, 2011) - Timmins Gold Corp. ("Timmins Gold" or the "Company") (TSX:TMM) is pleased to announce an updated reserve and resource estimate for the San Francisco Gold Project in the state of Sonora, Mexico that was previously updated on November 30, 2010. The National Instrument 43-101 ("NI 43-101") Technical Reports describing the details of the updated reserve and resource estimates will be filed on SEDAR (www.sedar.com) within 45 days from the date of this press release.

The Mineral Reserve and Resource estimate was prepared by MICON International Ltd. of Toronto. Ontario, using the Canadian Institute of Mining ("CIM") definitions for Mineral Reserves as required by NI 43-101. The updated mineral reserve and resource for the San Francisco Project which includes the nearby La Chicharra open pit is derived from information obtained from a drill program of 700 holes of core and reverse circulation drilling totaling 94,193 meters completed between July, 2010 and June, 2011. The past producing La Chicharra open pit is located 2 kilometres west of the San Francisco open pit. The updated proven and probable reserves for the San Francisco open pit have been estimated at 1,214,000 ounces of gold, represented by 64,245,000 tonnes at 0.588 g/t gold. The updated proven and probable reserves for the La Chicharra open pit have been estimated at 116,000 ounces of gold represented by 8,146,000 tonnes at 0.445 g/t gold. This is a 104% increase over the proven and probable reserves of 780,000 ounces (34,932,000 tonnes at 0.695 grams per tonne), net of production depletion of 129,000 gold ounces.

  1. Mineral resources are based on a gold price of $1,200 per ounce
  2. An internal cutoff grade of 0.128 g/t gold was used for measured & indicated and inferred ounces
  3. The inferred resources include material outside of the pit shell. It has the potential to become additional reserves of the San Francisco mine at a future stage.

The Mineral Reserves are based on a gold price of US$1,100 per ounce. The reserve includes a dilution factor of 8.3% that takes into account the dilution of partially mineralized blocks in the model. An internal cutoff grade of 0.14 g/t gold was used for the proven and probable reserve estimate. Weighted average LOM gold recovery is estimated at 68.6% based on the new geological model and the respective metallurgical recoveries for each rock type generated for the deposit.

"This is a significant milestone for the Company, and the updated reserves now outline a 10 year mine life with a projected production rate of 100,000 gold ounces per annum. Based on the success of this drill program, the Company continues to drill aggressively at San Francisco and La Chicharra, and anticipates completing an additional 120,000 metres of drilling from July, 2011 to December, 2011," stated Mr. Bruce Bragagnolo, CEO of Timmins Gold Corp.
