Victor J.E. Jones, President and CFO of Great Quest Metals Ltd.
("Great Quest" or "GQ") (TSX VENTURE: GQ)(FRANKFURT: GQM), is
pleased to report that the Phase I drilling campaign recently
completed at the Company's Tilemsi phosphate project has confirmed
the presence of high quality P2O5 phosphate mineralization, showing
a strong correlation with the targets from the remote sensing study
and prior reconnaissance work carried out on the concessions.
A total of 275 drill holes for 5049 meters were drilled using
two contractors, covering a small portion of the company's 737 km2
project. The program was executed on 2 of the presently defined 5
target areas - the Tin Hina (TH) and Alfatchafa (AF) hills. The
highly prospective Chanameguille target was not tested in the
initial round of drilling. Only some of the visually
distinguishable occurrences of mineralization were sampled. At Tin
Hina drill holes intersected 2 distinct horizons (seams) of
phosphate mineralization. Seam "A" averaged 23.73% P2O5 present in
104 of the drill holes and averaged 1.43m thick at an average depth
of 6.62 m. These holes include 4 deeper holes which intercepted a
second seam which averaged 27.60% P2O5 with an average thickness of
1.75m at an average depth of 8.00m below the seam A. The lower seam
may extend further but shallow drill holes would not have
intercepted it. Successful drill holes cover a surface area of
approximately 6.75km2 on Tin Hina.
Drilling on the Alfatchafa target identified a single seam with
samples averaging 22.69% P2O5 from 72 drill holes with an average
thickness of 0.90 m at an average depth of 18.75m. Successful drill
holes covered an area of approximately 6.70km2 on this target area.
The overburden in both areas consists of loose sands and silts.
Assay results from the drill samples suggest the phosphate rock
in both target areas is identical and of very high quality. The
phosphate rock is very low on many of the common impurities that
plague phosphate ores including cadmium, and uranium, making it
amendable to direct application. It also has negligible organic
carbon and the CaO/P2O5 ratio points to ore clean of calcite. No
size fraction analysis or concentration tests were attempted in
this phase of work but historical work suggests that inexpensive
techniques could be used to achieve attractive concentrate grades,
and removal of alumina and ferro-oxides would be simple.
The average percent of analyzed major oxides in the phosphate
rock are presented below:

Mr. Ehud Levy a phosphate expert and Director of the company,
who up to two years ago was managing director of Bateman Chemical
Technologies, the Chemical division of the Bateman Litwin Group
stated, "the preliminary results from the exploratory drilling are
promising and show that the phosphate rock is of high quality,
which is most likely to make it suitable for direct application, as
well as phosphoric acid and fertilizer production." Natural
phosphate rock is favoured for the generally acidic soils of the
agricultural zones in Mali.
This first phase of drilling was accomplished using an aircore
drill rig for the first 36, followed by Rotary Air Blast "RAB" for
the rest of the holes. With both rigs, drilling in overburden
proceeded with samples taken every 1m. The sampling protocol
required that on or before entering the phosphate layer the sample
intervals were reduced to 25cm to enable overburden and seam
thickness determination. These phosphate rock samples were later
combined and shipped to the ALS Minerals facility in Bamako, Mali
for sample preparation. Sachets of the ground weighed samples were
sent to the ALS Minerals Vancouver lab for XRF analysis of P2O5 and
major oxides. ALS standards and standads from a third party source
were added to the sample list. Multi-element ICP analysis was also
carried out on selected samples, about 1 for every 10 samples.
This first phase of drilling has confirmed the presence of
significant areas of phosphate mineralization. A second phase is
planned that will follow up on the success and seek to extend areas
identified at both Tin Hina and Alfatchafa, which both remain open
in multiple directions, particularly to the east and south of Tin
Hina. Company prospecting and remote sensing work suggest the
mineralization could extend materially. The company also intends to
drill test the Chanameguille target and other targets to the north
of the areas drilled. The Company's Malian subsidiary is proceeding
with plans for continued drilling, bulk sampling, concentration
tests and preparation of a Preliminary Economic Assessment, which
will provide an initial techno-economic evaluation of the
project.
