11:55 AM EDT, 04/02/2024 (MT Newswires) -- Silver One Resources ( SLVRF ) overnight Monday reported the results of initial metallurgical testing on samples from the Candelaria silver mine in Nevada using a novel, cyanide-free leaching process developed by Extrakt Processing Solutions (EPS) that can potentially double silver recoveries and cut leaching times.

The company said the results showed a significant increase in Candelaria's leach pad silver recoveries, exceeding 100% in comparison to previous testing using cyanide leaching.

A statement noted the sample tested consisted of leached oxides from LP1 and has an average silver grade of 48.1 g/t. Crushing the leach pad material to about 2 mm returned an average silver recovery of 49% in comparison to the cyanide leach test recoveries of 21% to 29% from past tests, the company said.

Silver One added that additional short-term milling to 550 and 110 microns increased the leach pad recoveries to 59.9% and 64.4%, respectively.

Silver One said it plans to conduct additional testing on material from both the existing leach pads and fresh ore during the second half.

"The impressive results from the initial testing using EPS' technology have encouraged Silver One to expand this testing to cover both leach pads and fresh mineralization," chief executive Gregory Crowe said in a release. "The use of these proprietary solutions yields potential for possibly doubling silver recoveries in comparison to traditional cyanide leaching. This may positively impact the overall economics of the project," Crowe added.

The company's shares were last seen up C$0.015 to C$0.20 on the TSX Venture Exchange.
