:: BacTech Environmental Ends Participation in Telamayu Project


BacTech Environmental Corporation has announced that it will not proceed with the reclamation of the Telamayu tailings project in Bolivia. After completing metallurgical test work on the project and evaluating the economics of the project it was decided that the project would be too difficult to finance. It was estimated that the project would cost up to $US 9M.

The inability to recover tin into a suitable concentrate severely hampered the economics of the project. Given the fact the value of the tin made up roughly 50% of the value of the contained metal in the tailings financing the project was deemed to be too difficult.

BacTech will continue to pursue arsenopyrite opportunities in Ecuador and other Andean countries that allow for the use of the Company's proprietary bioleach technology. Bioleaching produces a stable form of arsenic, ferric arsenate, as a by-product of the bioleach process. Since the beginning of 2019 the Company has visited the Ponce Enriquez area of southern Ecuador to meet with small mine producers of arsenopyrite. BacTech hopes to establish a bioleach processing facility that would offer an alternative to the small miners who presently sell concentrates to Asia at reduced prices due to high arsenic levels.
