FORWARD‐LOOKING STATEMENTS

This news release contains "forward‐looking statements" within the meaning of Canadian securities legislation. Such forward‐looking statements concern Goldsource's strategic plans and expectations in the PEA for the development of the Eagle Mountain; the amount of future production of gold over any period; post‐commissioning cash operating costs per ounce of gold; estimated pre‐production capital cost; and the Company's ability to commission for Phase I production during Q4, 2015. Such forward‐looking statements or information are based on a number of assumptions, which may prove to be incorrect. Assumptions have been made regarding, among other things: conditions in general economic and financial markets; ability to realize the PEA and develop and finance the project; accuracy of the interpretations and assumptions used in calculating inferred mineral resource estimates; availability of mining equipment; availability of skilled labour; timing and amount of capital expenditures; performance of available laboratory and other related services; and future operating costs. The actual results could differ materially from those anticipated in these forward‐looking statements as a result of the risk factors including: the timing and content of work programs; results of exploration activities and development of mineral properties; the interpretation of drilling results and other geological data; the uncertainties of resource estimations; uncertainty as to actual capital costs, operating costs, production and economic returns at the Eagle Mountain; reliance on the PEA; and general market and industry conditions. Forward‐looking statements are based on the expectations and opinions of the Company's management on the date the statements are made. The assumptions used in the preparation of such statements, although considered reasonable at the time of preparation, may prove to be imprecise and, as such, readers are cautioned not to place undue reliance on these forward‐looking statements, which speak only as of the date the statements were made. The Company undertakes no obligation to update or revise any forward‐looking statements included in this news release if these beliefs, estimates and opinions or other circumstances should change, except as otherwise required by applicable law.
