In a report released following its testing at Met-Solve Laboratories in Langley, BC, the company said the most recent work on its material returned an assay head grade of 1.45 grams per tonne, but by applying a multi-stage rougher flotation procedure to that same material, it found up to 75.9% of the gold was recovered.
Additionally, a three-stage cleaning process of a rougher concentrate was able to generate a final cleaner product with a grade of 66 g/t of gold.
"It should be noted that the average grade of the indicated mineral resource in the company's tailings deposit is, in fact, 1.83 g/t," it said. "Thus, assuming a similar concentration ratio, management is hopeful that, on average, an even higher-grade concentrate may be achieved."
New Carolin said its next step will be to perform further engineering and logistical work with the goal of optimising the recovery process and evaluate overall economic potential of reprocessing.
"Further cleaner flotation investigation will potentially optimize the efficiency of the cleaning circuit and improve on the final cleaner concentrate grade. In a closed-circuit setting, the recycling of the cleaner tailings streams is also expected to increase the Au recovery to the final concentrate," the company added.
Junior miner New Carolin is 100% owner of Ladner, located near Hope, BC in the Coquihalla Gold Belt.
