Continental Gold Limited (TSX:CNL) announced preliminary metallurgical results for the Buriticá project located in Antioquia, Colombia.
As quoted in the press release:
Highlights
- Selective rougher flotation on previously unprocessed samples resulted in the production of a high-grade Pb-Au-Ag concentrate and a Zn concentrate with total gold and silver recoveries of 97.04% and 95.65%, respectively. Based on the preliminary metallurgical results achieved to date, selective rougher flotation is the ideal process for Buriticá samples based on the high gold and silver recoveries and the low mass pull of material.
- A large proportion of the precious metals can be extracted using gravity separation with an average of 78.05% of the gold and 30.19% of the silver recoverable as free gold and silver.
- Gravity concentration followed by cyanidation on gravity tails resulted in gold and silver recoveries of 97.81% and 57.04%, respectively.
- Gravity concentration followed by flotation on gravity tails and cyanidation on flotation tails resulted in gold and silver recoveries of 99.44% and 99.36%, respectively.
- Cleaner flotation on previously unprocessed samples resulted in gold and silver recoveries of 94.13% and 92.31%, respectively.
- Test work to date indicates that generally there are no significant amounts of deleterious elements with Mercury below detection limits and a low arsenic content averaging 0.04% (range 0.003% – 0.18%).
- The specific gravity for the samples taken from veins averaged 3.2.
Continental Gold CEO, Ari Sussman commented:
“The metallurgical results confirm that mineralization from Buriticá is non-refractory and further optimization work will produce a final flow-sheet resulting in very high recovery rates for both the precious and base metal component of this deposit,” commented Ari Sussman, CEO. “It is particularly pleasing to us that although the veins in the Yaragua System, the Veta Sur System and the breccia mineralization are chemically distinct, they are all amenable to the same metallurgical processing.”
