Timmins Gold Corp. (“Timmins Gold” or “the Company”), is pleased to announce that recent diamond drilling at its flagship San Francisco Mine, Sonora state, Mexico, has confirmed the presence of at least three, high-grade, sub-parallel, gold bearing structures, all of which are located approximately 50-100 metres from surface along the south wall of the current open pit. Exploration information indicates that the lenses extend up to 300 m along strike and 200 m down dip. Select results include: 4.5 m averaging 5.5 g/t Au at 9 m downhole (TFD-153); and 3.0 m averaging 6.2 g/t Au at 6 m downhole (TFD-160).
CEO Bruce Bragagnolo commented: “Results from our drill programs underneath and along the edge of the San Francisco pit indicate the potential to increase the mineral reserves and resources at San Francisco and also improve our average grade. The drilling beneath the pit has confirmed our geological theory that the high grade structures are relatively continuous along the south wall of the pit and may extend along strike underneath the ultimate pit design. It also appears that these structures may extend beyond the eastern edge of the pit. The proximity of the mineralization to the existing pit suggests that it may be accessible by means of limited underground development from the current open pit. Given the size and grade of the structures, underground mining at the pit may offer significant economic benefits, which our technical staff will continue to evaluate during 2015.”
Additionally, the Company carried out an RC drill program adjacent to existing pit operations which has supported the interpretation of the underground structures and which demonstrates the potential for higher near-term open-pit grades at current operations. Select results include: 29.0 m averaging 3.5 g/t Au at 18 m downhole (TF-3609); and 13.8 m averaging 8.0 g/t Au at 46 m downhole (TF-3594).

San Francisco Pit South Wall Diamond Drilling
During the last quarter of 2014, the Company completed 2,172 m in 20 diamond drill (core) holes evaluating the area immediately south of the current pit. The drilling was designed to follow up on the theory of Timmins Gold geological staff that the orogenic nature of the deposit may provide the potential for the discovery of high grade feeders. Previous drill results have indicated the presence of high grade structures proximal to and down dip of the existing pit. Select results (all true width) include:
|Drill Hole No.||Depth|
|Section Line||Mineral Intersections|
Drilling was oriented along rough NE section lines spaced 50 to 100 m apart. Predominantly vertical holes were drilled to test the continuity of mineralization from surface to below the current pit. Grades and widths intersected by the recent drilling compare well to the historical data.
Interpretation by Company geologists has identified three distinct structural zones in the southern wall of the San Francisco pit that remain open at depth. The lenses average approximately 4 m in thickness, lie within 50 to 100 m of the current open pit limit, and dip between 30 to 45 degrees to the N-NE. Exploration information indicates that the lenses extend up to 300 m along strike and 200 m down dip (this does not include the down dip extensions of the lenses, which have not yet been drilled sufficiently to warrant interpretation).

A portion of the high-grade mineralization may extend into the ultimate open-pit design. The Company has initiated trade off studies to evaluate the economic benefits that may result from underground exploitation of the south wall. The Company plans to continue evaluating the south wall area during 2015.

In-pit RC drilling
Timmins completed 9,046 m of drilling in 73 reverse circulation (“RC”) holes at various locations throughout the pit. These holes were designed to provide additional information to support operations and also to test areas where prior positive drill results warranted follow-up drilling. Select results (not true width) include:
|Drill Hole No.||Depth|
|Section Line||Mineral Intersections|
The 2014 RC drilling program, carried out adjacent to current operations, was very encouraging. Several holes intercepted significant mineralization over good widths at relatively shallow distances from surface. This could indicate the potential for an improvement in grades in near-term operations. Holes TF-3594 and TF-3595 are of particular interest since they were drilled to the east of the pit in an area with relatively little historical information. They indicate the potential for the high grade structures from the south wall to extend upwards to the eastern wall of the pit and are potentially the extension of the original San Francisco gold vein. This lends further support to the interpretation of the high-grade structures at the south wall (as described in the above section).
Quality Control / Quality Assurance:
The drilling results contained in this news release have been prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects. Duplicates, standards and blanks were inserted into the sampling stream at intervals of 25 samples. The sampling of, and assay data from, drill core is monitored through the implementation of a quality assurance – quality control (QA-QC) program designed to follow industry best practice. Drill core (HQ and NQ size) samples are selected by the Company’s geologists and sawn in half with a diamond saw at the project site. Half of the core is retained at the site for reference purposes. Sample intervals vary from 1 to 1.5 m in length. Reverse circulation chips are sampled in the filed under the supervision of the geologist over regular intervals of 1.5 meters, cutting are collected from the cyclone discharge and the are passed through a riffle splitter to produce a final sample to send to the lab of approximately 6-9 kilos, the reject material is placed in plastic rice bags with the sample tag and stored on site, a witness of similar size to the final samples sent to the lab is also stored for future checks, if is needed. Samples are prepared at the ACME and ALS Labs facilities in Hermosillo and analyzed using a standard fire assay with a 50 gram pulp and Atomic Absorption (AA) finish at the same labs in Vancouver, Canada. Check assays were sent to each lab and were cross referenced and results verified.

Cautionary Note to United States Investors
The Company is subject to the reporting requirements of the applicable Canadian securities laws, and as a result it reports its mineral reserves and resources according to Canadian standards. Canadian reporting requirements for disclosure of mineral properties are governed by 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 Industry Guide 7 (“Guide 7”) of the Securities and Exchange Commission (the “Commission”). 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, the Company reports “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 Commission and generally, U.S. companies are not permitted to report resources in documents filed with the Commission. 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 Commission.
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 it cannot be assumed 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.
It cannot be assumed that all or any part of Measured or Indicated Resources will ever be converted into Mineral Reserves, and it cannot be assumed 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 Commission.
