BacTech Announces Assay Results for Telamayu Tailings

TORONTO, CANADA--(Marketwire - Aug. 1, 2012) - BacTech Environmental Corporation ("BEC" or the "Company") (CNSX:BAC)(OTC:BCCEF) (WKN:A1H4TY) today announced the assay results of the composite sample taken in May of this year from stored samples from the former mill of Telamayu. The Telamayu tailing site is 1 of 26 sites identified by the Bolivian government for remediation, and the Bolivian government advised the Company it is the only one, to date, to have had a systematic sampling program.

Silver and copper values were 282 g/t and 1.7% respectively, illustrating the high-grade nature of the tailings. This compares favorably with COMIBOL's results from 2005, having reported 258 g/t Ag and 1.05% Cu. COMIBOL is the Corporación Minera de Bolivia, the state-owned mining company of Bolivia. In addition, sulphide values were over 5%, which would be responsible for the acid drainage coming from the tailings.

The assay work on the composite sample was conducted by Inspectorate Exploration and Mining Services Ltd. ("Inspectorate"), in Vancouver, Canada. The composite sample was taken from over 2,000 bags of samples collected in 2005 by COMIBOL. The COMIBOL sampling program, included five 2-meter by 2-meter wells that were hand dug from surface to depths ranging from 8 to 10 meters. The sample material obtained by COMIBOL was bagged at 1-meter intervals and stored in the old flotation building. The composite sample was bagged, sealed at the Telamayu mill and then shipped to Lima, Peru by SGS Bolivia S.A. ("SGS"), and subsequently transferred to Inspectorate for assaying. A representative of SGS supervised this sampling program. The Company has not investigated or verified the sampling program conducted by, or the assay results produced by, COMIBOL.

COMIBOL advised that the tailings were generated by a centralized milling operation that treated material from 2 local mines, namely Animas and Seven Suyos. At a site visit in February 2012 by Ross Orr, President of the Company, he observed that there is still infrastructure at Telamayu, including an operating rail line, a power substation, a reliable water source and a plant housing that could possibly be used to house flotation circuits.

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.

BacTech will now conduct metallurgical testing to determine the process for the recoveries of silver and copper. If an acceptable flotation concentrate can be generated, it would then be subjected to bioleach test work to address the refractory nature of the material.
