NEWFOUNDLAND – Marathon Gold Corp. of Toronto calls metallurgical tests of ore from its Leprechaun gold deposit in the central part of the province “very positive.” The results of several bench scales tests indicated that direct sulphide-gold floation followed by cyanide leaching, carbon-in-pulp, and electrowinning reocvered between 92.8% to 95.0% of the total gold.
Marathon said a 100-kg composite sample (80% of drill core samples from the Main zone and 20% from the Hanging Wall zone) was prepared. It had a head grade of 3.26 g/t Au, compared to the average Main zone grade of close to 3.00 g/t. The ore does not contain a significant amount of copper, arsenic or mercury, organic carbon or sulphides.
The tests were conducted by Thibault & Associates in Fredericton, NB.
