Tahuehueto Underground Development Exposes New Mineralization along Perdido Structure

2019-02-22 / @businesswire

Telson Mining Corporation (“Telson” or the “Company”) (TSX Venture – TSN) is pleased to provide a development update and reports significant assay results from underground development at its Tahuehueto Mine development and construction Project, Durango State, Mexico.

Highlights

Tahuehueto underground development along the major mineralized structure (see Figure 1), El Perdido, has now been extended approximately 150 meters along strike to the north-east from the Level 12 access decline. The first 60 meters of this development was designed to prepare reserves identified by previous drilling for mining, however, the development drift is being extended in continuous mineralization beyond known reserves/resources and to date has exposed approximately an additional 100 meters of continuous mineralization beyond the know drilling. Channel sampling results received to date within a portion of this development are presented below. (see Figure 2 & Figure 3) Additional channel sampling assay results within this new development mineralization will be disclosed when assay results are received by the Company.

Formulas:
1st calculate a metal factor: for base metals (gold price/31.1 g/Troy
oz)/ (base metal price*2.2kg/lb*10) = Base Metal Factor.
For Silver
Metal Factor = gold price/silver price.

All the above samples were submitted to SGS De Mexico. S.A. de C.V. independent laboratory located in Durango city Mexico. Assay methods utilized were GE_FAA313 and GE_ICP14B for gold and silver respectively with over-limits followed up with GO_FAG303, Multi-element GE_ICP14B for lead and zinc with over-limits assayed with GO_ICP90Q. Additional detail on assay methodology used can be found on SGS website at https://www.sgs.mx/en/mining

2018 Pre-production Summary

Pre-production mining produced approximately 37,711 tonnes of ore with average grades of 3.86 g/t Gold, 43.6 g/t Silver 3.92% Zinc, 0.24% Copper, 2.10% Lead,
Approximately 818 tonnes of lead concentrate produced from pre-production was sold during with average grades of 82.22 g/t Au, 878.72 g/t Ag, 41.03% Pb and 2.50% Cu for approximate gross proceeds of US $3.41 million.
1,244 tonnes of zinc concentrate produced from pre-production was sold during the 2018 fiscal year with average grades of 49.38% Zn, 91.95 g/t Ag and 6.92 g/t Au for approximate gross proceeds of US $1.41 million.

Mine Construction & Development Summary

Telson advanced a total of 1.44 km of underground development, 365 meters within ore which supplied the pre-production toll milling feed and 1,074 meters in waste preparing the mine for future commercial production. Development included the Level 12 decline, the El Perdido development drift, El Creston development drift, the Haulage level portal and the main access decline for Level 20.

Mill construction, although somewhat behind schedule from unexpected construction delays, is progressing with concrete foundations nearing completion. Steel structures are currently being erected to house the floatation and filtration equipment while grinding and crushing areas are also under construction. (See Image 1 and Image 2) Preparation of the mine laboratory and camp facilities are nearing completion. Water pumping system is under construction in its first stage with the access road completed and pumping stations sites cleared.

For accounting purposes, any sale proceeds from pre-production prior to the Company declaring commercial production are considered directly attributable toward advancing those assets to the condition necessary for them to be capable of operating in the manner intended by management, therefore these are capitalized as a reduction of mineral interest and development assets.

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. Telson 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.
