Goldsource Updates Preliminary Assessment Files Quarterly Statements VANCOUVER, BC – December 14, 2010 – Goldsource Mines Inc.

(“the “Company”) is pleased to report that the results of an independent Preliminary Assessment NI 43-101 Technical Report, being prepared by Marston Consultants (“Marston”) of Calgary and EBA Engineering Consultants (“EBA”) of Vancouver for the Company’s 100%-owned Border coal project, located in east-central Saskatchewan, are expected to be announced prior to year end.

This Preliminary Assessment will present various preliminary technical and economic scenarios and provide the Company a basis from which to consider the most likely alternatives for the possible ongoing development of the property. Amongst other issues, the report will address potential markets and uses for the Border coal.

Several coal technologies for energy production are under review including clean coal power generation, coal quality upgrading, coal gasification and coal to liquids.

Preliminary results suggest that at this time, the most likely viable market for the Border coal is a coal-to-liquids process.

In conjunction with the Preliminary Assessment, the environmental baseline work conducted by EBA will serve as the basis for permitting for Goldsource’s potential future operations. Subject to the recommendations of the pending Preliminary Assessment and the securing of adequate financing, the Company has planned a winter program that would entail a bulk-sampling program for coal-to-liquids test work which would include the extraction of 5 to 10 tonnes of coal.

In addition Goldsource will drill several of the new geophysical targets, with a view to substantially increasing its current resource base. Current coal resources at Border include: - Indicated Resources: 63.5 million tonnes - Inferred Resources: 89.6 million tonnes - Speculative Resources: 18.7 million tonnes Based on the results of the work carried out in this year’s drill program, the Company is anticipating that the Preliminary Assessment will show revised resources in which some of Goldsource’s previous Inferred Resources have been converted to Indicated Resources. In April of 2010, the Company completed a detailed airborne gravity geophysical program over the known priority coal deposits at Border.

The gravity survey was implemented to test coal deposit boundaries and better define coal deposit size.

Successful definition of coal boundaries within plus or minus 20 metres appears to be possible using these airborne survey techniques.

Several new targets have been identified that are substantially greater in size than the deposits identified to date and a number of known deposits show boundaries beyond those currently established.

The Company has filed on SEDAR its Financial Statements and Management Discussion and Analysis for the three and nine month periods ending September 30, 2010.

The Financial Statements show that the Company has working capital of $1,394,261 at the end of the period. “It is encouraging to note that coal prices seem to be on the rise once again and the demand for global energy and coal fired power generation specifically seems to go unabated” said J.

Scott Drever, President for Goldsource.

“The realization that many alternative forms of electrical energy generation are simply not adequate to meet base loads or the growing demand and are generally extremely expensive is beginning to be recognized in many areas.

This realization should bring a more balanced approach to the uses of fossil fuels than we have seen in the recent past which will be beneficial to the long term prospects for the development of the Border coals as a significant energy source.” Goldsource Mines Inc.

is a resource company engaged in the exploration and development of Canada’s newest coalfield in the province of Saskatchewan.

The Company has aggressively drilled only a portion of this new thermal coalfield and has discovered 17 coal deposits of varying size with coal zone thicknesses up to 126 meters within the permit area of the Border Coal Project.

An experienced management team, who has accumulated a century’s worth of international mining success, leads Goldsource.

The Company has headquarters based in Vancouver, BC. The Qualified Person under National Instrument (NI 43-101) Standards of Disclosure for Mineral Projects for this News Release is N.
