BacTech Releases Positive Flotation Results for Telamayu Tailings

TORONTO, CANADA -- (Marketwired) -- 04/28/14 -- BacTech Environmental Corporation ("BacTech") (CSE: BAC)(OTC: BCCEF) (WKN: A1H4TY) announced today the initial flotation results for the Telamayu tailings project located in Potosi state, Bolivia.

BacTech enlisted the services of SGS Bolivia S.A. to oversee the sampling of some 2,000 bags of tailings assembled by COMIBOL, the Bolivian state mining company. In essence material was bagged at 1 meter intervals by COMIBOL from 8 test holes of roughly 10 meters in depth. A "pipe" was used to extract a sample from every bag and a larger sample of 200 kg was created. This larger sample was bagged and secured at site before making its way to Lima, Peru. From there, the samples were shipped to Inspectorate Exploration and Mining Services Ltd. in Vancouver, Canada. The Company has not investigated or verified the sampling program conducted by COMIBOL.

(i)Copper recovery is 33-35% of the remaining unoxidized sulphides in the tailings.

It was noted that roughly 50% of the sulphides in the sample had been oxidized. Two rougher kinetic flotation tests were carried out on the sample at different grinds to evaluate the tailings response to flotation. Results from these preliminary tests showed that after four stages of rougher flotation approximately 15% of the material was removed to a bulk rougher concentrate assaying 31-35oz/t silver (60-64% recovery), 4.2-4.4% (33-35% recovery) copper and 0.65% arsenic. Additional tests will be undertaken to attempt to improve the recoveries for the silver component.

In addition to silver and copper the assays showed significant values reported for tin, antimony and bismuth. Gravity work will also be undertaken to compliment this preliminary flotation work. The objective will be to evaluate possible benefits of applying both techniques for upgrading metals of value into concentrates for further treatment. For example the tin grade of the sample was assayed at 0.157% equating to 3,900 tonnes of contained tin (current price $23,500/t).

The copper recovery into concentrate at first glance would appear to be disappointing but upon further investigation it appears that approximately one half of the copper was extracted before flotation into the grind/wash water. If this is the case then recoveries of up to 80% were achieved if the wash water is included in the calculation. That is to say an operation may include a washing process from which the soluble copper is recovered prior to flotation.

BacTech will continue to investigate different approaches combining gravity for free silver and tin with flotation for silver and copper.

About Telamayu

COMIBOL advised that the tailings at Telamayu were generated by a centralized milling operation that treated material from 2 local mines, namely Animas and Seven Suyos. The site contains some infrastructure including an operating rail line, a power substation, a reliable water source and a plant housing that could possibly be used to house a flotation circuit. COMIBOL has estimated that there are approximately 2.3M tonnes of tailings attributable to the above assay results, and across the river is an additional 3M tonnes of tailings from the same source, but no work has been initiated there at this time. In addition, there are 2 additional tailings sites within 50 km that could be investigated in future.

The tonnages provided by COMIBOL are of a historical nature and have not been confirmed by the Company. BacTech is not treating the historical estimate as current mineral resources or mineral reserves as they are not NI 43-101 compliant. The Qualified Person ("QP") on the press release is Gary Williams, P.Geo.

BacTech Profile

BacTech Environmental Corporation holds the perpetual, exclusive, royalty-free rights to use the patented BACOX bioleaching technology for the reclamation of tailings and mining waste materials. In November 2011, BacTech signed a contract with the Mines Branch of the Manitoba Department of Innovation, Energy and Mines, to remediate an arsenopyrite gold stockpile situated at the Snow Lake Mine in Snow Lake, Manitoba. The Company continues to field enquiries globally with respect to additional opportunities for remediation.

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
In today's enterprise, digital transformation represents organizational change even more so than technology change, as customer preferences and behavior drive end-to-end transformation across lines of business as well as IT. To capitalize on the ubiquitous disruption driving this transformation, companies must be able to innovate at an increasingly rapid pace. Traditional approaches for driving innovation are now woefully inadequate for keeping up with the breadth of disruption and change facin...
