VANCOUVER, British Columbia -- (Business Wire)
Telson Mining Corporation (“Telson” or the “Company” (TSX-V, OTC
Pink-SOHFF, Frankfurt-TSGN (formerly SQ82)) is pleased to announce
results of historic Leachox Processtesting for the possible
increase of gold and silver recoveries on the Campo Morado tailings
material in 2013 by Maelgwyn Mineral Services of Cardiff UK.
Highlights
Final Tails
-
The test work achieved a maximum gold dissolution of 65 % after an
effective 10 passes
of Aachen oxidation, at a grind specification of 80% - 20 μm.
-
The maximum silver dissolution of 75% was achieved after an effective
40 passes of
Aachen oxidation, at a grind specification of 80% - 40 μm.
Reforma Zone Sample

The test work achieved a maximum gold dissolution of 45% after an

-
The maximum silver dissolution of 81 % was achieved after an effective
40 passes of
Aachen oxidation, at a grind specification of 80% - 10 μm.
In Telson’s ongoing quest to maximize the returns from Campo Morado
production, the Company has recently become aware of and had discussion
with, senior members of Maelgwyn Mineral Services, Maelgwyn
conducted preliminary testing of samples from Campo Morado in 2013 for
Nystar, the project’s former owner. The samples were from 2013 process
tailings, presumably G9 Zone, as well as fresh mineralization from the
Reforma deposit, a future production zone.
The Leachox testing indicated that substantial increases in precious
metal recoveries could be available at Campo Morado using Maelgwyn
Leachox Process. Very positive results were obtained in the 2013 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. The report stated, “It
should be noted that the above test work was peformed at a scouting
level only and higher recoveries would probably be achieved with
optimisation work”.
“The Leachox precious metal recovery testing conducted byMaelgwyn demonstrates that significant increases up to 65% gold
and 81% silver are possible at Campo Morado” states Antonio Berlanga,
Telsons 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 mines
profitability by increasing the ounces of gold and silver produced at
Campo Morado.”
About Maelgwyn Minerals’ Leachox Refractory
Gold Process, a patented technology process.
Maelgwyn Mineral Services Ltd (MMS) holds a European Patent for its
Leachox process for the treatment of refractory gold ores. Over the 10
years since first receiving a European patent the Leachox process route
has become the industry leader in the low-cost recovery of gold from
refractory and sulphide orebodies. There is now world-wide installed
capacity of Leachox to recover over 3 million ounces per annum of gold
contained in sulphides in such operations as; the Kibali Mine in the
DRC, the Tongon Mine in Cote d’lvoire both now owned by Barrick Gold
(formerly owned by Rangold Resources), the TGME mine in South Africa
owned by Barberton Mines and the Vasilkovskoye Mine in Kazakhstan owned
by Vasilkovsky MMC
The Leachox process uses simple ultra-fine grinding equipment combined
with the Aachen Reactor; a proprietary low pressure, high shear mass
transfer device utilising oxygen to partially oxidise the sulphides.
When combined with the liberation of gold by the ultra-fine grinding of
concentrates it results in acceptable but, more importantly economic
gold recoveries.
The Leachox process is a partial sulphide oxidation process for the
recovery of gold and silver from sulphide minerals. Depending upon the
mineralogy a number of processes are used but central to the Leachox
process is the Aachen shear reactor. In the leach process, it enhances
the kinetics and reduces reagent consumptions (oxygen, cyanide and lime)
which otherwise can be prohibitive. The reactor is designed to introduce
a high degree of shear which removes passivating films that may lead to
loss of recovery.

About Telson Mining Corporation
Telson Mining Corporation is a Canadian based mining company with two
Mexican gold, silver and base metal mining projects. Effective May 15,
2018 Telson declared commercial production at its 100% owned Campo
Morado Mine, which is currently producing zinc and lead concentrates
with gold, silver and copper as by-products.
Telson's 100% owned Tahuehueto Project, located in north-western Durango
State, Mexico is currently in construction development. Pre-production
commenced at Tahuehueto in August 2017, currently mining at a rate
averaging approximately 200 tonnes per day and shipping ore to a
third-party toll mill for processing. Management has a targeted timeline
at Tahuehueto to be producing with its own on-site mineral processing
plant, with a designed capacity of at least 1,000 tonnes per day, Q3-Q4
2019.
Metal concentrate deliveries and sales are well underway from both
projects.
