TORONTO, Dec. 1, 2011 /CNW/ - Aldridge Minerals Inc.

('Aldridge' or the 'Company') is pleased to announce the results of its metallurgical study of Yenipazar ore conducted by G&T Metallurgical Services LTD ('G&T') of Kamloops BC.  In total, ten samples weighing a total of approximately 90 kilograms of gravity pre-enriched Yenipazar material was used for the testing.  The sample was taken from five drill holes selected to be as representative as possible of the overall resource grade at Yenipazar.

One of the major goals of the study was to examine the potential to produce a gravity recoverable gold or 'Pan' concentrate prior to floatation.  Five open circuit cleaner tests were conducted with a gravity circuit to test this option.  The following comments were made by G&T regarding the gold gravity concentration.  'The tests clearly indicate that about 50% of the gold is recoverable by gravity concentration'.  Aldridge is very pleased with this result, especially since total gold recoveries assumed in its Preliminary Economic Assessment ('PEA') filed on SEDAR February 3(rd), 2011 were only 37% and in our previous testing, approximately 90% of the gold in floatation reports to the copper concentrate.

Cyanidation tests were then conducted to test the potential to leach this Pan concentrate to recover the gold and silver from this gravity concentrate.  G&T reported that 'Bottle roll cyanidation tests on the pan concentrate using 1,000 ppm sodium cyanide, extracted about 79% of the gold in the feed'.  'When the dosage of sodium cyanide was increased to more intensive conditions (10,000 to 20,000 ppm) the gold extractions increased to over 97%' after a time period of 48 hours.  Again, Aldridge is very encouraged by these results.

In addition to the gravity gold testing, several rougher tests and one locked cycle test were completed.  The lone locked cycle test produced three separate copper, lead and zinc concentrates.


-- The copper concentrate graded 19.6% at a total recovery of 72%
and contained 30.3 g/t gold (a recovery of 24%) as well as 482
g/t silver (at a recovery of 15%).
-- The lead concentrate graded 64.3% at a total recovery of 51%
and contained 1111 g/t silver (45% recovery) and 4.7 g/t gold
(5% recovery).
-- The zinc concentrate graded 57.7% at a recovery of 77% and only
contained 59 small amounts of silver and gold (1.14 g/t Au and
59 g/t Ag at recoveries of 5% and 2% respectively).
-- These recoveries compare quite favourably to those in our PEA
where total recoveries for Au, Ag, Cu, Pb and Zn were only 37%,
57%, 77%, 78% and 59% respectively.

'These results are a solid improvement in our recoveries from those of the PEA.  Additionally, now that we know we can recover approximately 50% of our gold in a Pan concentrate, we will continue  to work on increasing the leachability of this concentrate and to establish even higher recoveries of gold in the floatation circuits as well.  Internally, our aim is to consistently recover at least 80% of the gold from Yenipazar with more than half of this being produced in a doré bar after leaching our Pan concentrate' said Jacob Willoughby, President of Aldridge.  The metallurgical work for the Yenipazar definitive feasibility study will be completed by SGS UK in conjunction with Gekko Systems.
