Positive Metallurgical Results From Cervantes Drill Core

VANCOUVER, BC - Aztec Minerals Corp. reported positive bottle roll gold recoveries from metallurgical test-work conducted by Bureau Veritas on the California porphyry gold-copper drill core from the Cervantes property in Sonora, Mexico.

Drill core samples were grouped into 4 separate types of mineralization (domains), Oxide 1, Oxide 2, Mixed Oxide/Sulfide and Sulfide. Highlights of the bottle roll gold recovery results are as follows: 85.1% recovery on 2.0mm material and 94.3% on 75 micron material in sample Oxide 1; 87.7% recovery on 2.0mm material and 94.2% on 75 micron material in sample Oxide 2; 77.9% recovery on 2.0mm material and 89.0% on 75 micron material in sample Mixed Oxide/Sulphide; and 51.2% recovery on 2.0mm material and 78.7% on 75 micron material in sample Sulphide.

"We are pleased to report these very positive early stage metallurgical tests which indicate that the California oxide, mixed oxide/sulfide, and sulfide gold zones should be amenable to cyanide heap leach or agitated leach processing methods. More detailed test-work is needed to draw any definitive conclusions but these results are a great start,” said Joey Wilkins, President and CEO.

The 4 domains were defined by mineralization type, gold grade, and depths to fit the possibility of a future open pit mining scenario. Testing was conducted for 240 hours, although good recoveries generally plateaued at 48 hours, and the tests showed low cyanide and lime consumption.
