[{"type":"text","content":"July 10, 2018 / TheNewswire / Toronto, Canada - BacTech Environmental Corporation (\"BacTech or the Company\"),(CSE:BAC, OTC:BCCEF) today gave an update of results of an on-going bioleach study being conducted at Laurentian University in Sudbury, Canada from which design information is being obtained to build a bioleach plant for refractory gold concentrate processing in Ecuador. The study was based on materials collected by a third party in late 2017 from the Ponce Enriques (\"PE\") area of southern Ecuador. Ponce Enriques is a well-known mining district in Ecuador that produces significant amounts of arsenopyrite concentrates from small and/or artisanal miners. The collected material was sourced from small mining operations in PE and included concentrate, whole mineralized material and tailings. The material was bagged and shipped to Dr. Nadia Mykytczuk at Laurentian University in Sudbury. Dr. Mykytczuk is a noted biomining professor at the University and has worked closely with BacTech for several years. A bioleach program was developed by BacTech's Dr. Paul Miller with the test work being managed, guided and co-ordinated by Dr. Mykytczuk and her team at Laurentian. In addition, the project was awarded a grant of $150,000 from the Ontario government's Ontario Center of Excellence. Arsenic BacTech is pleased to announce that all of the materials tested to-date have responded well to the bio-oxidation testing procedure indicating a high amenability to bioleach processing demonstrating that high oxidation levels are achievable. Importantly, samples of neutralised arsenic precipitate containing stabilised arsenic, have been subjected to Toxicity Characteristic Leach Procedure (TCLP) testing showing that these precipitates are environmentally stable and benign meeting US EPA or equivalent regulatory requirements for disposal. This TCLP test work was conducted by TESTMARK Laboratories Ltd., an independent organization. Ross Orr stated, \"This is an important milestone in the on-going bioleach test work programme in that it demonstrates the environmental responsibility of the process as a technically advanced method for treating arsenical gold materials in Ecuador. \" A second round of test work will begin immediately at Laurentian optimising the pulp density of concentrates in the bioleaching process and for optimisation of conditi...
