Angelim Property – Zone 1 Initial Tests<br />

3 samples of 90 kg each were sent to NOMOS Laboratory for Initial Metallurgical Tests<br />

AMALGAMATION PROCESS:<br />

During this stage, chemical process<br />

simulates the physical activities of<br />

gravimetry.<br />

Au Head Cont: 22,11ppm<br />

Au Head Cont: 5,10 ppm<br />

Average recovery of the contained gold<br />

by gravity was 57%<br />

CYANIDATION PROCESS:<br />

The three samples analyzed recovered 90%<br />

of the Au, in particle sizes below 0.25 mm,<br />

in a period between 14 to 16 hours by<br />

cyanidation leaching.<br />

An ideal grinding granulometry of 0,150mm<br />

is taken as optimal, once the samples<br />

showed about 50% by weight in this size<br />

range (BS001-46,9%; BS002 59.47%; BS003-<br />

45,08%).<br />

Au Head Cont: 4,69 ppm<br />

Based on these characteristics, a small scale<br />

contained, closed loop CIL/CIP modular<br />

processing plant has been selected.<br />
