High Grade Zinc/Gold Core. (3 replies and 3 comments)

Combination of high grade Zinc/Gold in a VMS system is very rare ie: 5m of 12% Zinc 14g/t Gold 1%Cu in a core sample. Can someone explain the structure and the significance of this unusual occurrence. Thanks.

Hello Blue, I am not sure what it means in terms of geology. As far as metallurgy, you will need to see if you can recover most of your gold away from the Zinc concentrate because the typical payable is only 65-70% of the value after a 2 g/t deductible. If you can recover that Au by gravity or in a Cu concentrate you'll get 95-98% pay.

What is your %Fe content?

Thanks Bob for your reply. I will see if that info is available.

Hi Bob, the Fe content is 6%. Is 6% a high value and what would a high/low Fe content represent? Thanking you in advance.

A Gold-Zinc Operation is Minera Florida in Chile. I attached a 43-101 report. See Section 16. They cyanide leach the Zinc/Au rougher concentrate & clean it after to make a high grade Zn conc. Not something easily implemented on Vancouver Island. Have a look at the geology section.

Thanks David for replying. Although a quartz vein deposit, I managed to find one high grade Gold/Zinc core, 1m @ 20g/t Gold and16% Zinc. The odd thing was there was no other cores in the district that even came close to those values That particular vein was not mined because of core length.
