Lake Shore Gold Corp. ("Lake Shore Gold" or the "Company") today announced preliminary cash operating cost(1) and AISC(2) per ounce sold for the first half ("H1/15") and second quarter ("Q2/15") of 2015. Final numbers for these measures will be available when the Company issues its H1/15 and Q2/15 financial and operating results on July 30, 2015. Cash operating cost per ounce sold in H1/15 is estimated at approximately US$551 (including US$26 per ounce for royalties) compared to US$588 reported in the first half of 2014 ("H1/14"). AISC per ounce sold in H1/15 is estimated at US$810 versus US$862 in H1/14. Total production costs in H1/15 are estimated at approximately $67.0 million versus full-year 2015 guidance of $125 million. All financial numbers are in Canadian dollars unless otherwise indicated.

Based on estimated unit costs in H1/15, the Company announced on July 8, 2015 that it was revising its unit cost guidance for full-year 2015. Cash operating cost per ounce sold is now targeted to be below US$650, which compares to the previous guidance of between $650 and US$700. The target for full-year AISC per ounce sold has been revised to better than US$950 from between US$950 and US$1,000 previously.

For Q2/15, preliminary cost estimates include cash operating costs of US$597 per ounce sold (including US$24 per ounce for royalties) and AISC per ounce sold of US$879. Both unit cost measures were in line with the Company's revised guidance for full-year 2015. Total production costs for Q2/15 are estimated at approximately $34.0 million.

Tony Makuch, President and CEO of Lake Shore Gold, commented: "Our unit cost performance in both H1/15 and Q2/15 was very strong, with cash operating costs and AISC for both periods comparing very favourably to our revised full-year guidance. While a weaker Canadian dollar definitely helped us, another key factor driving our performance was the continued effectiveness of our people in finding ways to improve efficiency and produce ounces at low unit costs. Low-cost production continues to be a key driver of our success and of our strong competitive position within the gold mining industry."

Footnotes

1. Cash operating costs and cash operating cost per ounce are Non-GAAP measures. In the gold mining industry, cash operating costs and cash operating costs per ounce are common performance measures but do not have any standardized meaning. Cash operating costs are derived from amounts included in the Consolidated Statements of Comprehensive Income (Loss) and include mine site operating costs such as mining, processing and administration as well as royalty expenses, but exclude depreciation, depletion and share-based payment expenses and reclamation costs. Cash operating costs per ounce are based on ounces sold and are calculated by dividing cash operating costs by commercial gold ounces sold; US$ cash operating costs per ounce sold are derived from the cash operating costs per ounce sold translated using the average Bank of Canada C$/US$ exchange rate. The Company discloses cash operating costs and cash operating costs per ounce as it believes the measures provide valuable assistance to investors and analysts in evaluating the Company's operational performance and ability to generate cash flow. The most directly comparable measure prepared in accordance with GAAP is total production costs. A reconciliation of cash operating costs and cash operating cost per ounce to total production costs for the most recent reporting period, the three months ended March 31, 2015 and 2014, is set out on page 16 of the Company's first quarter 2015 MD&A filed on SEDAR at www.sedar.com and at www.lsgold.com.
   
   
2. All-in sustaining cost is a non-GAAP measure. This measure is intended to assist readers in evaluating the total costs of producing gold from current operations. While there is no standardized meaning across the industry for this measure, the Company's definition conforms to the all-in sustaining cost definition as set out by the World Gold Council in its guidance note dated June 27, 2013. The Company defines all-in sustaining cost as the sum of production costs, sustaining capital (capital required to maintain current operations at existing levels), corporate general and administrative expenses, in-mine exploration expenses and reclamation cost accretion related to current operations. All-in sustaining cost excludes growth capital, growth exploration expenses, reclamation cost accretion not related to current operations, interest and other financing costs and taxes. The most directly comparable measure prepared in accordance with GAAP is total production costs. A reconciliation of all-in sustaining cost to total production costs for the most recent reporting period, the three months ended March 31, 2015 and 2014 is set out on page 17 of the Company's first quarter 2015 MD&A filed on SEDAR at www.sedar.com and at www.lsgold.com.
