Lake Shore Gold Announces 29% Increase in Ore Reserves

TORONTO, ONTARIO--(Marketwired - March 12, 2015) - Lake Shore Gold Corp. (TSX:LSG)(NYSE MKT:LSG) ("Lake Shore Gold" or the "Company") today announced results of the Company's annual reserve update, which includes a 29% increase in total reserves to 773,300 ounces (5,483,000 tonnes at an average grade of 4.4 grams per tonne). The 29% increase in reserves from the previous year's estimate of 598,800 ounces (4,039,000 tonnes at an average grade of 4.6 grams per tonne) beat the Company's target of replacing reserves mined in 2014.

Reserves at Timmins West Mine grew 4% to 509,700 ounces (3,691,000 tonnes at an average grade of 4.3 grams per tonne) from the previous estimate of 492,200 ounces (3,332,000 tonnes at an average grade of 4.6 grams per tonne). Reserves at Bell Creek Mine more than doubled from the previous estimate, increasing to 263,600 ounces (1,792,000 tonnes at an average grade of 4.6 grams per tonne) from 106,600 ounces (706,900 tonnes at an average grade of 4.7 grams per tonne). The strong growth in reserves at Bell Creek Mine significantly extends the mine's reserve life and also provides the Company with an opportunity to increase production going forward.

A total of 122,000 metres of drilling was completed in 2014 at Timmins West and Bell Creek largely focused on converting resources to reserves. Following the new reserve update, the Company continues to have a large resource base to support future additions to reserves, and also has numerous opportunities to grow resources through drilling for extensions at the existing operations and for new discoveries. In 2014, exploration drilling to the southwest of Timmins West Mine resulted in an important new discovery within 500 metres of Thunder Creek. The 144 Gap Zone is a large zone covering 350 metres along strike and 350 metres down dip, which remains open for expansion.

Tony Makuch, President and CEO of Lake Shore Gold, commented: "The primary objective of drilling at both Timmins West Mine and Bell Creek Mine in 2014 was upgrading resource classifications and converting resources to reserves. We surpassed our goal of replacing reserves mined in the year by doubling total reserves at Bell Creek and adding to our reserves at Timmins West Mine. In 2015, our goals are to replace reserves mined during the year as well as increase our overall resource base to drive further reserve expansion. The 144 Gap discovery is the focus of our exploration program in 2015 with our target being to establish a first resource for the end of the year. Moving forward, our key priorities remain to consistently achieve safe and efficient operations, generate significant free cash flow, replace the reserves we mine and build resources in support of long-life production and long-term value creation.

"Looking at our performance, we are having a strong first quarter of 2015, with production, average grades and unit costs on track to beat expected levels. We have also continued to generate net free cash flow, with cash and bullion having increased more than $10 million so far this year, to approximately $72 million. We have also continued to reduce debt, with three payments remaining on our senior secured credit facility."

CAUTIONARY NOTE TO U.S. INVESTORS REGARDING RESOURCE AND RESERVE ESTIMATES

The mineral reserve and mineral resource estimates contained in this press release have been prepared in accordance with the requirements of the securities laws in effect in Canada, which differ from the requirements of United States securities laws. The terms "mineral reserve," "proven mineral reserve" and "probable mineral reserve" are Canadian mining terms as defined in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and the Canadian Institute of Mining, Metallurgy and Petroleum' (the "CIM") - CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended. These definitions differ from the definitions in SEC Industry Guide 7 under the United States Securities Act of 1933, as amended. Under the SEC Industry Guide 7 standards, a "final" or "bankable" feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority.

In addition, the terms "mineral resource," "measured mineral resource," "indicated mineral resource" and "inferred mineral resource" are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves. "Inferred mineral resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. 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 pre-feasibility studies. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Disclosure of "contained ounces" in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade without reference to unit measures.

Accordingly, information contained in this press release that contain descriptions of the Registrant's mineral deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations thereunder.

The Company does not intend, and does not assume any obligation, to update these forward-looking statements. These forward-looking statements represent management's best judgment based on current facts and assumptions that management considers reasonable, including that operating and capital plans will not be disrupted by issues such as mechanical failure, unavailability of parts, labour disturbances, interruption in transportation or utilities, or adverse weather conditions, that there are no material unanticipated variations in budgeted costs, that contractors will complete projects according to schedule, and that actual mineralization on properties will be consistent with models and will not be less than identified mineral reserves. The Company makes no representation that reasonable business people in possession of the same information would reach the same conclusions. Forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. In particular, delays in development or mining and fluctuations in the price of gold or in currency markets could prevent the Company from achieving its targets. Readers should not place undue reliance on forward-looking statements. More information about risks and uncertainties affecting the Company and its business is available in the Company's most recent Annual Information Form and other regulatory filings with the Canadian Securities Administrators, which are posted on sedar at www.sedar.com, or the Company's most recent Annual Report on Form 40-F and other regulatory filings with the Securities and Exchange Commission.
