VANCOUVER, BC - Victor J.E. Jones, Chairman and CFO of Great Quest Metals Ltd. (TSXV: GQ; Frankfurt: GQM), reports that the Company has received the analysis of Landsat TM7 images covering its 737 sq km Tilemsi Phosphate Project, comprising the Tin Hina and Tarkint Est phosphate concessions, located in eastern Mali. The study used images of the region collected by the Japanese Advanced Land Observing Satellite (Daichi) in late 2010, which were then digitally processed and tessellated to provide high-resolution colour photos, digital terrain maps (DTM) and spectral band analysis for phosphates. The phosphate analysis used band combinations and band ratio algorithms in selected regions of the electro-magnetic infra-red spectrum based on signatures taken from the USGS spectral library to create a pictorial image of surface hydroxy-apatite, a phosphate mineral. In addition, spectral responses from areas of known phosphate mineralization were used to characterize the expected response from areas with phosphate potential.

The analysis for phosphate mineralization identified extensive showings along the fringes of low hills across both concessions. The findings require follow up field work but are consistent with the sampling carried out by the Company in 2009 and prior work done by others. Company sampling, reported earlier, found a range of phosphate grades from 5.11% to 33.05% P205 over 26 samples with an average of 24.5%. The remote sensing analysis suggests extensive apparent phosphate mineralization. The study confirms the need for the drilling program, scheduled to begin within weeks, and assists in prioritizing further detailed geological reconnaissance over more areas within the concessions. The high resolution digital terrain maps will also assist in determining field work access routes and sampling locations. The analysis and interpretation map are located on the Company's website at

The Company has also now completed the drilling of the initial water well to service the exploration camp and executed a drilling contract for the initial drilling phase on the Tilemsi Phosphate Project of some 1000 holes to be drilled on 250 m spacing over the initial target areas. Logistical and sampling plans are in final stages of development and implementation with mobilization of the air-core drill expected next month. The objective of this first phase drilling program is to establish a preliminary NI 43-101 compliant phosphate resource
