Great Quest Metals Ltd.: Mali Agricultural Product Demonstrations an Overwhelming Success

Great Quest Metals Ltd. (the "Company" or "Great Quest") (TSX
VENTURE:GQ)(FRANKFURT:GQM) is pleased to announce that it is in receipt of the
quantitative results from the product trials discussed in the November 21, 2013
Press Release. The demonstrations have been a tremendous success, showing that
the Great Quest's direct application fertilizer is an effective replacement for
much costlier imported chemical phosphate across the full range of crops and
regions of Mali.
The study comprised 27 agronomic trials covering the five major agro-ecological
climatic regions of Mali, where large-scale commercial agriculture occurs. The
comprehensive trials provided results for all of Mali's most important crops:
cotton, maize (corn), rice (irrigated, upland and lowland varieties), millet,
sorghum, cowpea (or black-eyed pea), and peanuts using GQ blends of enriched
high grade (35% P2O5) and enriched medium grade (27% P2O5).
Following are some of the most compelling results, with the full work to be
published shortly on completion of the report by the Institute for Rural
Economic Development ("IER"), the Company's Malian government research partner.
The crop demonstrations were performed to compare our new enriched processed
blends, the commonly used chemical blend NPK 15-15-15, and the unprocessed
natural powdered phosphate rock. The natural powder is crushed rock from the
Tilemsi project with no beneficiation and no solubility agents. It is known to
be a good fertilizer but historically has not been fully effective in the first
year of use. The expected result was for the unprocessed powder to be the least
productive, the diammonium phosphate to be the most productive and the GQ
formulations to perform better than the unprocessed, but not as well as the
diammonium chemical phosphate. However in many cases the GQ blends out performed
the chemical fertilizer, and in several cases the natural powder performed in
line with the chemical fertilizer.
Some complications with the addition of potash during sample preparation
resulted in low potash quantities in the test blends. This has put the GQ blends
at a disadvantage compared to the chemical blend, however the GQ blends still
performed comparably. This is likely because the organic nature of the phosphate
allowed the nutrient to be used more efficiently by the plants, compensating in
terms of yield for the low level of potash. Sulfur and boron were added to some
blends as solubility agents.
Example 1
Corn from the Sikasso Region, NPK formulation using diammonium phosphate versus
NPK using GQ 35% direct application phosphate rock. The GQ enriched blends
showed higher crop yields up to 3,858 kg/ha compared to diammonium phosphate
based blends of 2,156 kg/ha, and up to 4098 kg/ha when solubility agents are
added to the GQ blends.

Example 3
Peanuts from the Kita Region, using diammonium phosphate versus GQ 27% direct
application phosphate rock used in isolation with no added nitrogen or potash
fertilizer. Diammonium phosphate incorporates some nitrogen into the fertilizer
and is considered a one stop shop for some farmers. However, head to head the GQ
medium grade granule showed yields up to 1436 kg/ha compared to 904 kg/ha for
diammonium phosphate.
