Great Quest Files NI 43-101 Technical Report on SEDAR for the Tilemsi Phosphate Project, Mali

VANCOUVER, BRITISH COLUMBIA (August 23, 2012) - Joel Jeangrand, President and CEO of Great Quest Metals Ltd. ("Great Quest" or the "Company") (TSX-V: GQ, FRANKFURT: GQM) is pleased to announce that, further to its news release of November 8, 2011, the Company has filed a National Instrument 43-101 ("NI 43-101") compliant mineral resource estimate with respect to its Tilemsi Phosphate Project, located in eastern Mali, West Africa.

This document entitled "Tilemsi Phosphate Project, Mali - Resource Estimate" (the "Report"), dated August 16, 2012 was prepared for Great Quest by Jed Diner (M.Sc., P.Geol.), an Independent Qualified Person as defined by NI 43-101. The Report is available on SEDAR under the Company's profile at www.sedar.com and on the Company's corporate website www.greatquest.com.

The Report is based on the first phase of the Company's drilling program on target areas of Tin Hina and Alfatchafa, within the Tilemsi license, one of Great Quest's three phosphate licenses. The Report follows the news release dated November 8, 2011 and validates an Inferred Mineral Resource of 32 million tonnes at a grade of 23.4% P2O5 (at a cut-off of 5% P2O5).

The Company confirms that to-date, there is no new material scientific or technical information concerning the inferred resource estimate related to the target areas of Tin Hina and Alfatchafa, within the Tilemsi license, that has not been included in the Report.

The readers are cautioned that:

(i) Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
(ii) The quantity and grade of reported inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category.

On a separate note, the Company welcomes the nomination of a unity government in Mali on August 20th, 2012 and its announcement to deal with the situation in Northern Mali as a priority. The Company will communicate further on the matter in a subsequent news release.

ON BEHALF OF THE BOARD OF DIRECTORS OF GREAT QUEST METALS LTD.
