Telson Mining Corporation (CVE:TSN) has reported encouraging historic leachox testing from its Campo Morado tailings material at the mine of the same name in the Guerrero State, Mexico.

Maelgwyn Mineral Services of Wales, UK conducted preliminary testing of samples from the project in 2013 for Nystar, the project’s former owner, of which Telson is now aware.

Very positive results were obtained that year in testing for both of the samples submitted with a maximum recovery of 65% gold and 75% silver at a grind size of 20 microns from the process tailings sample and a maximum recovery of 45% gold and 81% silver at a grind of 40 microns from the Reforma deposit sample, said Telson.

Maelgwyn holds a European Patent for its Leachox process for the treatment of refractory gold ores. It has become the industry leader in the low-cost recovery of gold from refractory and sulphide orebodies

The Leachox process uses ultra-fine grinding equipment combined with the Aachen Reactor, which is a proprietary low pressure, high shear mass transfer device utilising oxygen to partially oxidise the sulphides.

"The Leachox precious metal recovery testing conducted byMaelgwyn demonstrates that significant increases up to 65% gold and 81% silver are possible at Campo Morado” said Antonio Berlanga, Telson's CEO.

"Should additional planned Leachox testing of optimization work to confirm recoveries, ultimate best grind size and reagent additions show a path forward to a commercial installation of this technology, we could improve recoveries from current levels of gold at 15-20% and silver 30-40%, which would significantly increase the mine's profitability by increasing the ounces of gold and silver produced at Campo Morado."

Shares were unchanged at $0.36.
