BacTech Environmental Launches Peru Initiative for Mine Tailings Reprocessing
September 3, 2026 — Leads & Copy — BacTech Environmental Corporation today announced the launch of its initiative in Peru, focusing on the reprocessing of historic mine tailings through bioleaching. The Company has established a wholly owned Peruvian subsidiary, BacTech Verde Peru S.A.C., to facilitate this venture.
The subsidiary will review the Peruvian government's inventory of historic mine tailings, many of which contain elevated arsenic content and are amenable to bioleaching. BacTech aims to identify potential reprocessing opportunities for gold, silver, and copper from these tailings. However, the Company has not yet entered into any agreements with the government or other parties for specific tailings projects and has not secured access to any commercial opportunities. There is no guarantee that any such arrangements will be made or that specific projects will be secured.
BacTech's proprietary bioleaching process, BACOX®, has been previously used at four commercial plants built under license. For tailings that have undergone crushing and grinding, they may be re-floated to produce a sulphide concentrate suitable for bioleaching to recover gold and silver as a doré. The technical and economic viability for any particular tailings in Peru has not yet been determined and will be contingent on the results of future test work and studies.
In addition to BACOX®, BacTech is developing its patent-pending Zero Tailings™ technology. If successfully developed and commercialized, this technology is expected to recover precious and base metals, as well as produce marketable by-products such as magnetite, an ammonium sulphate fertilizer, and silica. Zero Tailings™ has not been commercially proven, and there is no assurance of its successful development, commercialization, or application to any tailings in Peru. The Company also announced a separate tailings program in Kazakhstan on September 1, 2026.
Currently, most arsenopyrite concentrates produced in Peru are processed in China. A long-term objective for BacTech is to help establish a domestic processing option for high-arsenic material, thereby retaining value within Peru. The initial phase of the Peru initiative involves reviewing the government's inventory of tailings that require remediation. Should suitable targets be identified, BacTech plans to engage with relevant authorities regarding a potential commercial arrangement, which could include royalty payments to the government or local communities.
BacTech has appointed Neil Tito Acosta Mariños as the Company’s country manager for Peru. Mr. Acosta, based in Trujillo, brings extensive field experience to the role. The Peru initiative is in its early, exploratory stages and faces significant risks and uncertainties, including the identification and access to suitable tailings projects, obtaining necessary governmental, regulatory, and community approvals, negotiating commercial arrangements, and demonstrating acceptable technical and economic results from test work. There can be no assurance that any pursued project will prove economically viable.
BacTech Environmental Corporation is a leader in commercial bioleaching, using naturally occurring bacteria to recover metals and stabilize harmful elements like arsenic. The Company operates a permitted 50-tonne-per-day bioleach facility in Ecuador and is developing its Zero Tailings™ technology in Canada. BacTech trades on the Canadian Securities Exchange (CSE: BAC), the OTCQB (OTCQB: BCCEF), and the Frankfurt Stock Exchange (FSE: 0BT1).
