Temex Achieves Excellent Gold Recoveries up to 98% on Preliminary 
Metallurgical Testwork, Whitney Project, Timmins 
TORONTO, Feb. 27, 2013 /CNW/ - Temex Resources Corp. (TSX-V: TME, FWB: TQ1) 
("Temex" or "the Company") is pleased to announce that it has received 
excellent preliminary results of metallurgical testwork on the Hallnor gold 
deposit in Timmins, Ontario. The historic and prolific Hallnor mine, the 
centerpiece of the Whitney Project, was the highest grade gold producer in the 
Timmins camp having produced 1.7 M ounces of gold at 0.40 ounces (12.4 g) gold 
per tonne. Current in-pit NI 43-101 compliant resources are 776,100 ounces 
grading 2.08 g/t gold measured and indicated, and 231,900 ounces grading 1.79 
g/t gold inferred and the deposit is wide open along the mine trend for 2 
kilometres to the west including the Broulan Reef Mine. 
Highlights: 


    --  Cyanidation leach tests yielded excellent gold recoveries
        ranging between 93 to 98%
    --  Leach times are considered fast with low consumption of
        reagents
    --  Gravity tests are considered excellent producing high grade
        concentrates and confirming the presence of free gold
    --  Gravity concentrate with gravity tail leaching yielded gold
        recoveries between 94 to 97%
    --  Additional testing could further improve gold recoveries

"We are extremely pleased with the exceptional results of our preliminary 
metallurgical testwork at Hallnor which is another important step forward in 
our fast-tracking this project on the pathway towards production. The results 
today demonstrate that very high gold recovery is achievable and it is 
particularly noteworthy that excellent recoveries were achieved on all 
testwork methods which indicated not only the presence of free milling gold 
that is rapidly recoverable in short time frames but also with low reagent 
consumption suggesting low milling costs," commented Ian Campbell, President 
and CEO.

The work conducted by SGS Canada Inc. concluded that cyanide leaching on whole 
ore at various grinds between K(80) of 51 to 143 microns (µm) produced 
excellent gold leach recoveries ranging between 93% and 98% on calculated head 
grades ranging between 0.94 to 2.32 g/t gold respectively. Excellent results 
were also achieved on a variety of alternate and combined techniques including 
gravity concentration, flotation and cyanide leaching. The report 
recommended that the potential to reduce milling costs and improve gold 
recovery through optimizing these techniques still exists with further testing.

The metallurgical testwork was conducted on three composites: one master 
composite (1.91 g/t gold) and one each high grade (3.23 g/t gold) and low 
grade (1.22 g/t gold) sub-composites from 180 kg composed of 224 individual 
core samples. The core samples were representatively selected from 55 drill 
holes across the ore body by P&E Mining Consultants Inc. of Brampton, Ontario 
and sent to SGS Laboratories in Vancouver, B.C.

The metallurgical testwork reported here for gold in the three composites 
consisted of 1) whole ore cyanidation (CN) extraction, 2) gravity 
concentration recovery, 3) whole ore flotation recovery, 4) gravity tail 
flotation recovery, and 5) gravity tail CN extraction. Table 25 from the SGS 
report is presented below:

Whole Ore CN Leaching

All the whole ore leach tests, irrespective of the variable tested, produced 
excellent gold leach recoveries ranging between 93% and 98% at respective 
grind sizes of 80% passing 50 µm (microns) up to 143 µm (microns). The 
results show that gold leach recovery increased with fineness of grind with 
the best results achieved at finer grinds. The first 6 hour gold leach kinetic 
tests were fast and extending the leach time beyond 24 hours did not improve 
the results. The cyanide and lime consumptions were less than 0.5 kg/t and 0.8 
kg/t respectively and are considered low.

Flotation Tests

Flotation tests on whole ore produced excellent gold recoveries ranging 
between 85% and 95% for all three composites at grind sizes between K(80) of 
52 to 161 µm (microns). The flotation of gravity tails resulted in gold 
recoveries of 82 to 91%.

The combination of gravity + gravity tail flotation resulted in gold 
recoveries of 90 to 95%.

Gravity Tests

Each composite test charge was ground to the target size and tested using a 
laboratory model Knelson MD-3 concentrator prior to being upgraded on a Mozley 
mineral separator. The gravity concentrate was assayed to extinction for 
gold by standard fire assay methods. The gravity tailings gold assays were 
assayed in duplicate. The report concluded that gravity separation at grinds 
of 80% passing 133 to 143 µm (microns) recovered 34 to 45% of the gold in the 
concentrate and were considered "excellent". The concentrate grade ranged from 
1,136 g/t to 3,046 g/t gold at upgrade ratios of 854 to 1081 times head grade.

The combination of gravity + gravity tail leaching increased the gold recovery 
to 94 to 97%.

Chemical Analyses

The gold assays of the composites were determined by pulp and metallic (P&M) 
approach. The gold assays of the composites were determined by screen 
analyses protocol, screening at 150 mesh (105 microns). 
Pulverizing/screening at 150 mesh continued until the oversize fraction was 
approximately 30 to 50 grams at which point the coarse fraction was analyzed 
for gold to extinction by standard fire assay methods and the combined fine 
fraction was blended, riffled down and assayed in duplicate.

Work Program and Outlook

The ongoing metallurgical program will follow up on the SGS recommendations 
towards optimizing processing techniques and operating cost saving 
opportunities. The objectives will be to investigate and compare the 
benefits of stand-alone vs. custom milling opportunities as a number of gold 
milling facilities are located close by, may be amenable to this ore type and 
prove economically even more attractive.

The Whitney Property is held under a joint venture in which Temex owns 60% and 
Goldcorp Canada Ltd. (("Goldcorp"), on behalf of the Porcupine Gold Mines 
Joint Venture (a joint venture between Goldcorp Inc. and Goldcorp)) owns 
40%. Temex is the operator of the joint venture.
