Independence Gold Recovers Up to 97.9% Gold From 3Ts Property, British Columbia - Seite 2
Floatation Testwork
A single test was conducted on each of the gravity tailings to assess further recoverability of gold and silver, with the concentrate being submitted for assaying and mineralogy. From these
tailings, Composite 1 recovered 76.0% gold and 74.8% silver remaining in the stream, while Composite 2 recovered 64.1% gold and 84.8% silver.
Cyanide Leaching
The floatation tailings were submitted for bottle roll cyanide leaching tests, lasting for 48-hours with a pH of 10.5 to 11. Both composites performed well
and recovered additional gold in the pregnant leach solution. Composite 1 recovered 16.4% gold and 17.1% silver from the floatation tailings, while Composite 2 recovered 6.18% gold and 7.07%
silver.

It is believed that recoverability could be further improved by modifying the processes and with additional mineralogical studies to understand deportment of the gold and silver within the Tommy Vein compared to the Ted-Mint Offset Vein.
