VANCOUVER, BRITISH COLUMBIA (October 23, 2012) - Joel Jeangrand, President and CEO of Great Quest Metals Ltd. (the "Company") (TSX-V: GQ, FRANKFURT: GQM) is pleased to announce that an updated resource estimate on the Tilemsi Phosphate Project has resulted in an increase of 17.4 million tonnes of inferred phosphate resource at an average grade of 25.9% P2O5. At a 10% cut-off grade, the updated resource estimate represents a 53% increase of the Tilemsi phosphate resource reported by Great Quest in the NI 43-101 Technical Report filed in August 2012. Together with the previously estimated resources on the Alfachatfa and Tin Hina, two other areas within the Tilemsi license, the total inferred resource now stands at 50 million tonnes with an average grade of 24.3% P2O5 (at 10% cut-off).

This technical report entitled "Tilemsi Phosphate Project, Mali - Tarkint Est Area. Resource Estimate" (the "Report"), dated October 17, 2012, will be available shortly on SEDAR and on the Company's corporate website The Report is based on the second phase of the Company's drilling program conducted in the fourth quarter of 2011 on Tarkint Est, one of Great Quest's three phosphate licenses (see Map 1).

  • As can be seen from Table 2, the results show little sensitivity to cut-off grades, with most of the resource assays above 20%, which bodes well for future beneficiation processes.
  • Geochemical analyses of the phosphate samples indicate they are clean of deleterious elements
  • Average overburden in Tarkint Est is about 7.6m, which will result in a strip ratio of 5.7:1 (t/t). About 10% of the Tarkint Est resource occurs along the edges of the plateaus and could be mined without any stripping.

Property Description and Location:
The Tilemsi Phosphate Project comprises the contiguous Tilemsi, Tarkint Est, and Aderfoul licenses and covers a land package of around 1,206 sq. km. The Tarkint Est license covers 589 sq. km and hosts the target area of the late 2011 drilling campaign. The drilling tested 3 large plateau areas - the western In Tassit, the central Chenamagel and the eastern Tagit N'Ouerene.

Analytical Procedure:
This mineral resource estimate of work done to date on Tarkint Est is based on the data derived from 608m of Rotary Air Blast (RAB) drilling in 48 drillholes and 48 bulk samples, taken from outcrops and at shallow depths from trenches and excavations. All drilling protocols and geological sampling of the program were established by Mr. Jed Diner, MSc P.Geol. Drill cuttings were sent to ALS Bamako Minerals Laboratory and to ALS Laboratory in Vancouver, BC.

Great Quest President and CEO, Joel Jeangrand, commented:
"This latest resource report confirms that the Tilemsi deposit is graduating to become a world-class deposit, thanks to its increasing size and potential for low extraction cost. Given the extensive land surface of our project and the work done so far, we can only expect a substantial upsize potential on the project. An inferred resource of 50 million tonnes will greatly benefit the findings of our Preliminary Economic Assessment (PEA), expected to be completed in the fourth quarter of 2012."

Exploration and Development Initiatives:
The Company's exploration and development program on Tilemsi, designed to expedite the path to a production decision, includes of the following components:

  • Aircore drilling to upgrade 'inferred' resource into the 'indicated' category;
  • Pursuing the Company's exploration program on new target zones within the three concessions to increase the size of the project resource, as soon as the local geopolitical situation permits;
  • Completion of a Preliminary Economic Assessment by year-end;
  • Initiation of a product development and marketing strategy report;
  • Initiation of a Feasibility Study in 2013.

The readers are cautioned that:

  • 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. Estimates are rounded since the figures are not precise calculations.
  • 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.
  • The mineral resources in this report were estimated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council.

Qualified Person
Mr. Jed Diner, MSc. P.Geol., a Qualified Person as defined under NI 43-101, completed the mineral resource estimate and has reviewed the technical information presented in this release. Mr. Diner completed his MSc. in Applied Earth Science at Stanford University in 1983 and works internationally on mineral exploration and resource development projects. He has consulted on other phosphate projects in Uzbekistan, Peru and Angola. The resource estimate complies with the NI 43-101 for the Standard of Disclosure for Mineral Projects as adopted by the Canadian Securities Regulators.


The Company is also pleased to announce the appointment of Dr. Robert Rennie as Company Advisor. Recently retired as President and CEO of Spur Ventures, Dr. Rennie has over 27 years' experience in the fertilizer business. He began his career as a researcher working for the joint division of the FAO/IAEA of the United Nations and Agriculture Canada before being recruited by Esso Chemical to develop new and proprietary fertilizer products.
