VANCOUVER, British Columbia -- (Business Wire)
Telson Mining Corporation (“Telson” or the “Company”) (TSX Venture –
TSN) is pleased to report positive testing results for increasing the
SAG Mill throughput processing rate by at least 15% by reducing the size
of crushed mill feed.
Highlights
-
During 4 hours of testing 382 tonnes were milled at 80% -2 inch
obtaining an average processing rate of 95.5 tonnes/hour (equivalent
to 2,292 tonnes/day)
-
Testing at 80% -2 inch achieved approximately 15% increase over
processing 100% -5-inch feed.

Testing commenced at 08:00 hrs and ended at 12:00 hrs when no more
mineral was available at a size less than -2 inches. The current design
of the mills crushing circuit allows a minimum size of -5 inches to be
processed. Based upon Antonio Berlanga, CEO and mining engineer’s
experience in other mining operations working with similar milling
circuits, a significant increase in production can be achieved by
reducing the size of crushed mineral mill feed. The successful testing
just completed at Campo Morado was designed to confirm if this technique
could produce similar production increases. Of note is that the
available -2 inch mill feed was limited such that a maximum of 80% at -2
inches was processed over a four hour period.
Antonio Berlanga stated, “As Director of La Negra Mine, I was
responsible for increasing the mines processing rate by up to 37% by
reducing the mill ore feed from a traditional -3/8 Inches to -1/8
Inches. As one can see from our Campo Morado test results, feeding
smaller material to the SAG Mill increased the milling capacity up to
15%, showing clearly that by feeding a smaller size to the SAG mill it
is possible to increase its grinding capacity. Testing also showed that
the efficiency of other stages in the milling process, (vertical mill
(Vertimill), flotation cells, thickeners and filters) were not affected
by the higher throughput volume as zinc recoveries and quality of the Zn
concentrate at 47% Zn were maintained, showing that the mill worked
smoothly at increased capacity. “
With Telson’s just completed positive testing to verify if this
technique was applicable at Campo Morado, Telson now intends to modify
its crushing circuit to produce a consistent -2 inch feed and upgrade
the pumping system to allow effective movement of the increased volumes
in order to increase mill throughput and productivity while maintaining
excellent zinc concentrate grades. Management anticipates that with a
consistent 100% -2 inch mill feed, we can achieve mill throughput
processing rates in excess of the average 96 tonnes per hour (equivalent
to 2,300 tonnes per day) achieved over 4 hrs in the above testing.
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.
