Mali Agricultural Product Demonstrations an Overwhelming Success
 
VANCOUVER, BRITISH COLUMBIA (February 18, 2014) – Great Quest Metals Ltd (the “Company” or “Great Quest”) (TSX-V: GQ) 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 2
Rain watered Rice from the Bamako Region, NPK formulation using diammonium phosphate versus NPK using GQ 35% direct application phosphate rock. The GQ enriched blends showed yeilds up to 2,224 kg/ha compared with 1,751 kg/ha for diammonium phosphate based 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.
 

Phosphate Used	Quantity (kg/ha)	N (%)	P (%)	K (%)	S (%)	Yield (kg/ha)
Diammonium Phosphate Chemical	65	18	46			904
GQ 27% Phosphate	100		27			629

The significant yields shown in these results for the GQ – IER agronomic demonstrations provide further impetus to the development of a range of products from the Great Quest Tilemsi phosphate resource, for agriculture in Mali and West Africa.
