Clean Gold Oxide Mineralization

• Mineralogical studies (TESCAN® Metallurgical Test Work
and QEMSCAN®) defined that the

gold is free and very fine (3 µm to

7 µm)

• it is associated with oxide minerals
and quartz veinlets.

• There are no Cu, As, Sb, and Hg.
• There are no clay, sulfites, neither

carbonites. The gold is leachable.

• The results show an average gold

recovery of 75% can be obtained

in column leaching with material
crashed to P100 of 150 mm with a

P80 of 4”.

• The range of gold recoveries is 72%
to 78%.

• The test results support an average

gold recovery of 75%
