TORONTO--()--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 features multimedia. View the full release here: https://www.businesswire.com/news/home/20190301005213/en/

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. As previously released, about 72% of the metal value in the deposit comes from copper and gold at equal parts followed by the zinc value representing 22%. Toachi’s efforts were methodically sequenced for orderly recovery of these metals. Toachi announced the results of its maiden 43-101 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:

Zinc Concentrate Grade Recovery
Zn 50 - 52% 70 %
Au 13 g/t 25 - 27 %
Ag 125 g/t 26 %

Alain Bureau, President and CEO stated, “Today, we take another step in the right direction, with a metallurgical program corroborating that the material responds favorably to traditional flotation concentration processes. These results further support the immense confidence we have in the future economic viability of the La Mina deposit and represent a major milestone for our project.”

Table 1 shows a summary of results of the Locked Cycle Test LCT-1.

The results from LCT-1 will form the basis for the concentrator design in the upcoming PEA. Further metallurgical work will continue to optimize the process and also allows us to test the benefit of adding a gravity circuit and pyrite recovery on zinc flotation tailings.

Metallurgical test work was conducted by SGS Canada Inc. in Lakefield, Ontario, Canada, under the direct supervision of Dan Imeson, Manager, Mineral Processing. Dan Imeson has over 20 years of experience in the mineral processing field with SGS Canada.
