Toachi Mining Inc., (“Toachi” or the “Company”) (TSX-V:TIM) (OTCQB:TIMGF) is pleased to report excellent results from the on-going metallurgical test work on its “La Plata” project in Ecuador. This press release is a clarification of the release that was issued earlier on March 1, 2019 and at the request of IIROC to clarify the category of 43-101 resources estimate being in the inferred category.

During 2018, Toachi retained the services of SGS Canada Inc., from Lakefield, Ontario, (SGS) to conduct Bench Scale and Locked-Cycle Flotation test work on the La Mina Volcanogenic Massive Sulfide (VMS) deposit, part of its “La Plata” project in Ecuador. The results from this metallurgical program will be included into the ongoing Preliminary Economic Assessment (PEA), presently being completed by SGS Geological Services in Blainville, QC.

Toachi’s efforts were methodically sequenced for orderly recovery of these metals. Toachi announced the results of its maiden 43-101 inferred resource estimate completed for the La Mina VMS deposit on the La Plata concession on September 13, 2017. La Mina VMS deposit of 1.9 million tons at an average grade as follow:

Gold   Copper   Zinc   Lead   Silver
4.1 g/t   3.3 %   4.5 %   0.6 %   49.4 g/t

RESULTS

Four composite samples representing the expected zones of the ‘La Mina’ mineralized horizons have been tested at SGS Lakefield. Following a program of some 55 Rougher/Scavenger and bulk cleaner tests, the results show that the La Mina VMS polymetallic mineralization responded well to a conventional flotation flowsheet and produced saleable grade concentrates. Locked cycle tests (LCT-1) was conducted on the sample composite of the zone 300.

The flotation test work showed good metal recoveries, creating saleable Copper/Lead and Zinc concentrates. Copper/Lead concentrate showed the following grades and recoveries.

Copper-Lead Concentrate   Grade   Recovery
Cu   20 -23 %   88 - 90 %
Pb   4 - 5 %   70 - 72%
Au   13 g/t   41 -43 %
Ag   141 g/t   45 - 50 %

Zinc concentrate showed the following grades and recoveries:
