Timmins Gold Corp.: Updated Mine Plan and Increased Production Schedule for the San Francisco Mine in Sonora, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 23, 2011) - Timmins Gold Corp. (TSX:TMM)(NYSE Amex:TGD) announces the completion and filing of the technical report titled NI 43-101 F1 Technical Report Updated Resources and Reserves and Mine Plan for the San Francisco Gold Mine Sonora, Mexico, dated November 1, 2011, prepared by Micon International Limited of Toronto ("Micon"). The Technical Report was prepared to update the previous technical report dated November 30, 2010 and to provide a base case scenario for increased production at the San Francisco Mine as a result of rising gold prices and a 104% increase in the estimated mineral reserves at the mine.

Highlights - Projected Results

  • Total gold production of 810,065 ounces from 2011 to 2017
  • Expansion of crushing facilities from 18,000 tonnes per day to 32,000 tonnes per day in 2012
  • Average annual production of approximately 130,000 ounces of gold from 2012 to 2017
  • Base case life of mine cash costs of US$633 per ounce
  • Life of Mine Operating Profit of $455 million
  • Strip ratio of 2.1

Commenting on the Technical Report's results, Timmins Gold President Arturo Bonillas said: "The Technical Report continues to confirm the robust economics of the San Francisco Mine. The increase in the mineral reserves at the San Francisco Mine has been obtained from the successful drilling undertaken up to June 30, 2011 and higher gold prices. The decision to increase the capacity of the crushing system to 32,000 tonnes per day has been derived from a number of factors, including the successful drill program and resulting increase in estimated reserves, rising gold prices and the commensurate decrease in cutoff grade, and management's conviction that additional reserves are likely to be established in and around the pit and at La Chicharra as a result of the extensive drilling program of over 100,000 metres completed in the second half of 2011, the results of which are not yet incorporated into the Technical Report. A further updated NI 43-101 Technical Report incorporating drilling from July 1, 2011 is scheduled for completion in Q1 2012."

  1. Mineral resources are based on a gold price of US$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.


Metal Price Forecast

It can be seen that, at a gold price of US$1,200/oz, the San Francisco project exhibits robust economics over its projected remaining life of approximately 5.5 years. The life-of-mine average cash cost of producing gold is estimated at US$633/oz, and future capital expenditures are forecast to be relatively low.

Revenue projections are based on a constant gold price of US$1,200/oz in real terms, closely approximating the 3-year trailing average price but significantly lower than current spot prices. Accordingly, the sensitivity of the project to a gold price in a range of up to US$1,500/oz has also been evaluated. The economic analysis indicates that the project will yield present values of US$252 million at a discount rate of 5%/y and US$232 million at a discount rate of 8%/y. The expansion capital schedule principally in 2012 will be paid back rapidly through accelerated cash flows.

Base Case

The base case evaluation has been made for a nominal throughput rate of 32,000 tonnes per day, which is expected to be achieved in 2012. A summary of the base case life-of-mine statistics and annual cash flows are summarized in the table below.

Sensitivity Study

Sensitivity of the NPV to changes in gold price, operating and capital costs has been analyzed. Revenues are directly proportional to gold price, recovery and grade. With an adverse change of 25% (i.e., a reduction in gold price to US$900 per ounce), NPV remains strongly positive. At US$1,500 per ounce, undiscounted cash flow is estimated at approximately US$462 million.

Sensitivity of the project NPV has also been determined for a specified range of gold prices.

The following is a summary of Micon's conclusions:

  1. Micon recommends that as Timmins continues to define the mineralized lenses in its new model for the deposit, it snaps the interpretation to the drill holes for better definition and interpretation accuracy of the mineral lenses.

  2. Micon recommends that Timmins composites the grades within each mineralized lens rather than from the collar of the drill hole down to the toe as is now the case.

Given the known extent of mineralization on the property, compared to the amount of mining activity, the San Francisco project has the potential to host further deposits or lenses of gold mineralization, similar in character and grade to those exploited in the past, outside the present resource base.

Micon has reviewed the proposed exploration program for the property and, in light of the observations made in the Technical Report, supports the concepts as outlined by Timmins. Given the prospective nature of the property, it is Micon's opinion that the San Francisco project merits further exploration and that Timmins' proposed exploration plans are properly conceived and justified.

Cautionary Note Regarding Mineral Reserve Estimates

Timmins is subject to the reporting requirements of the applicable Canadian securities laws, and as a result we report our mineral reserves according to Canadian standards. Canadian reporting requirements for disclosure of mineral properties are governed by National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). The definitions of NI 43-101 are adopted from those given by the Canadian Institute of Mining, Metallurgy and Petroleum. U.S. reporting requirements are governed by the SEC Industry Guide 7 ("Guide 7"). These reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, but embody different approaches and definitions. For example, under Industry Guide 7, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. In particular, we report "resources" in accordance with NI 43-101. While the terms "Mineral Resource," "Measured Mineral Resource," "Indicated Mineral Resource" and "Inferred Mineral Resource" are recognized and required by Canadian regulations, they are not defined terms under standards of the SEC and generally, U.S. companies are not permitted to report resources in documents filed with the SEC. As such, certain information contained in this press release concerning descriptions of mineralization and resources under Canadian standards is not comparable to similar information made public by United States companies subject to the reporting and disclosure requirements of the SEC. In addition, an "Inferred Mineral Resource" has a great amount of uncertainty as to its existence and as to its economic and legal feasibility, and you cannot assume that all or any part of an "Inferred Mineral Resource" will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies. You are cautioned not to assume that all or any part of Measured or Indicated Resources will ever be converted into Mineral Reserves, and not to assume that all or any part of an "Inferred Mineral Resource" exists, or is economically or legally mineable. In addition, the definitions of "Proven Mineral Reserves" and "Probable Mineral Reserves" under CIM standards differ in certain respects from the standards of the SEC.

Cautionary Note Regarding Forward-Looking Statements

Certain statements contained herein may constitute forward-looking statements and are made pursuant to the "safe harbor" provisions of the United States Private Securities Litigation Reform Act of 1995 and Canadian securities laws. Forward-looking statements are statements which relate to future events. Such statements include estimates, forecasts and statements as to management's expectations with respect to, among other things, business and financial prospects, financial multiples and accretion estimates, future trends, plans, strategies, objectives and expectations, including with respect to production, exploration drilling, reserves and resources, exploitation activities and events or future operations. Information inferred from the interpretation of drilling results and information concerning mineral resource estimates may also be deemed to be forward-looking statements, as it constitutes a prediction of what might be found to be present when, and if, a project is actually developed.

In some cases, you can identify forward-looking statements by terminology such as "may", "should", "expects", "plans, "anticipates", believes", "estimates", "predicts", "potential", or "continue" or the negative of these terms or other comparable terminology. These statements are only predictions and involve known and unknown risks, uncertainties and other factors that may cause our or our industry's actual results, level of activity, performance or achievements to be materially different from any future results, levels of activity, performance, or achievements expressed or implied by these forward-looking statements.

While these forward-looking statements, and any assumptions upon which they are based, are made in good faith and reflect our current judgment regarding the direction of our business, actual results will almost always vary, sometimes materially, from any estimates, predictions, projections, assumptions or other future performance suggestions herein. Except as required by applicable law, Timmins Gold does not intend to update any forward-looking statements to conform these statements to actual results.
