Vancouver, British Columbia – May 29, 2009: Dr. Hikmet Akin, President of Aldridge Minerals Inc. (“Aldridge” or the “Company”) is pleased to announce that gravity pre-concentration of Yenipazar ore is proceeding well at Corem (Québec, Canada, see news release dated April 3, 2009)
The coarse-grained nature of sulphide mineralization at Yenipazar makes the ore potentially amenable to gravitational enrichment prior to the application of flotation. Gravitational pre-enrichment has the potential to lower the production costs by reducing the flotation feed and by improving the metal recovery process during flotation.
For a first test, the fine-crushed ore (80 % passing 0.44 mm) was screened at 0.106 mm, and the oversize material was passed over a shaking table to recover the heavy particles in 5 concentrates. Most of these particles are sulphides containing the target metals Cu, Pb, Zn, Au, Ag, but results indicate the presence of gravity-recoverable gold as well. From a sample head grade of 2.47 g/t Au, the first concentrate grades 20.11 g/t Au, representing 16.82 % of the total contained gold.
In this first test, recoveries are 91.75 % (Cu), 89.91 % (Pb), 95.01 % (Zn), 86.69 % (Ag), 89.29 % (Au) contained in 59.39 % of the feed mass. Mineralogical studies have shown that a better feed size would be 0.3 mm (100 % passing), because the sulphides are well liberated from the gangue minerals below 0.3 mm and will be better gravity-recoverable. Further tests are scheduled to address this issue, and the recovery of sulphides from the -0.106 mm material.
The Yenipazar project is subject to an earn-in agreement with Anatolia Minerals, wherein Aldridge can earn a 100% working interest, subject to a 6 % net proceeds interest (“NPI”, revenues less operational cost) until revenues of US$ 165 million are generated, and 10 % NPI from there on.
