BacTech Environmental Corp. (BAC:CSE; BCCEF:OTCQB; 0BT1:FSE) has signed a technical consulting and testing agreement with Di-As Company Ltd. to assess how its proprietary Bacox bioleaching technology might apply to historic tailings in the Zyryanovsk district (now Altay City) of East Kazakhstan, according to a September 1 release.
The three-stage program is fully funded by Di-As at an estimated US$350,000 to US$425,000 and is expected to run 26 to 34 weeks. Each stage is gated, allowing both parties to review results before proceeding.
Key Investor Takeaways
- Di-As funds a staged metallurgical program to test Bacox on sulfide-rich historic tailings containing gold and silver.
- Bacox uses natural microorganisms to oxidize sulfides, liberate metals, stabilize arsenic, and reduce long-term acid generation potential.
- The 36.57 million tonne historical estimate (1.16 g/t gold, 6.62 g/t silver) is not a current NI 43-101 resource and requires substantial verification work.
- Successful results could lead to a commercial licensing discussion, with Zero Tailings technology considered separately.
- The global tailings management market is projected to grow from US$12.23 billion in 2025 to US$18.36 billion by 2035.
- Market capitalization is at nearly CA$13.14 million with 238.87 million shares outstanding.
The agreement provides a low-risk entry point for BacTech to demonstrate its technology on material that conventional methods may struggle to process economically. Because Di-As covers all testing costs, BacTech avoids capital outlay while generating technical data that could support future licensing revenue.
Why the Agreement Matters Now
Historic tailings represent both an environmental liability and a potential metal recovery opportunity. Modern bioleaching can address both issues by oxidizing sulfides under controlled conditions.
The staged structure lets Di-As confirm technical viability before committing to larger investments, a model that aligns with disciplined project advancement.
BacTech's Core Technology Advantage
Bacox uses naturally occurring micro-organisms that draw energy from oxidizing sulfide minerals, exposing precious metals for later recovery and allowing elements such as arsenic to be treated and stabilized. Oxidizing sulfides under controlled conditions can also reduce the amount of reactive sulfide remaining in the treated material, potentially reducing a source of long-term acid generation and associated environmental-management requirements.
"This is exactly the type of technical challenge we believe Bacox is well suited to investigate — historic sulfide material containing precious metals that may be difficult to recover through conventional processing alone," BacTech President and Chief Executive Officer Ross Orr said. "It is also the first transaction structured to begin with Bacox, with zero tailings potentially to be added once that technology is commercialized."
Project Details and Next Catalysts
The Staroe facility received material from the former Zyryanovsk processing operations between 1953 and 1968. A State Reserves Committee of the Republic of Kazakhstan protocol dated Jan. 2, 2022, logs 36.57 million tonnes averaging 1.16 grams per tonne (g/t) gold and 6.62 g/t silver, along with zinc, lead, and copper. Those figures are a historical estimate, not current mineral resources or reserves under National Instrument 43-101; no qualified person has done enough work to reclassify them, and BacTech said it does not treat them as current, according to the release.
The agreement takes effect 30 days after the new CIL processing plant in Altay City is formally commissioned and carries an 18-month long-stop date, BacTech said. If the program succeeds, BacTech and Di-As may weigh a commercial arrangement to deploy Bacox, though any future development would still depend on further technical work, verification of the historical information, engineering, permitting, financing, and definitive agreements.
Three-Stage Metallurgical Program
BacTech said its three-stage metallurgical program will use physical samples from the Staroe facility, collected under Qualified Person supervision and analyzed by accredited laboratories. The first stage assesses the site and tests how much gold is tied to sulfides; the second compares Bacox biological oxidation with direct cyanidation for gold and silver recovery and evaluates sulfide oxidation and arsenic stabilization. If results support further work, the third develops preliminary engineering and costs for a nominal 50-tonne-per-day Bacox circuit, potentially expandable to about 100 tonnes per day, and assesses integration with Di-As's planned carbon-in-leach infrastructure.
The program will also yield information on how sulfides and arsenic behave in biological treatment, while any use of BacTech's zero-tailings technology would be considered separately, since it is not part of the current work and its suitability remains untested.
Broader Sector Timing and Market Growth
In a May 15, 2021, piece for Elements, Nicholas LePan drew attention to mining's environmental toll, focusing on tailings, the waste left over from processing ore that operators typically hold in dams or ponds around the world.
Drawing on figures from respected bodies such as the International Council on Mining and Metals, the United Nations Environment Programme, and the Principles for Responsible Investment, LePan put the global count at roughly 8,500 tailings storage facilities. Active, idle, or closed, those sites together hold about 217 cubic kilometers of tailings, enough to build a cube six kilometers on every side.
A Market Research Future report pegged the mining tailings management market at US$11.74 billion in 2024 and projects it will climb from US$12.23 billion in 2025 to US$18.36 billion by 2035, a compound annual growth rate (CAGR) of 4.15% across the 2025-to-2035 forecast window.

"Filtered tailings dominate the market, while thickened tailings are emerging as the fastest-growing segment due to their efficiency in resource recovery," Market Research Future noted. "Increased environmental awareness and regulatory pressures are key drivers propelling investment in sustainable mining practices."
Perspectives and Valuation Context
In his National Investor newsletter on March 23, Chris Temple wrote that "one of my very favorite themes in commodities/metals is not the metals stories themselves, ... but the various emerging sciences that lead to enhanced recovery of metals from old tailings, troublesome ores, etc."
He added, "I've long been an advocate of BacTech Environmental and its wares (which will one day pay off)."
In a 2025 opinion piece contributed to Streetwise Reports, he wrote, "To me, and having over the last year especially been close to several conferences and initiatives, the big, long-term story is going to be the inevitable, BIG adoption of technologies like BacTech's and others'. So, I'm still patient with that confidence."

Common Questions from Investors
How is the testing program funded and structured? Di-As funds the entire three-stage program at an estimated US$350,000 to US$425,000, with each stage dependent on positive results from the prior stage.
Is the historical tonnage a current mineral resource? No. The 36.57 million tonne figure is a historical estimate prepared under Kazakhstan's state system and is not equivalent to an NI 43-101 resource; substantial verification work would be required.
What happens if the tests succeed? The companies may discuss a commercial licensing arrangement for Bacox, though any development would still require further studies, permitting, and agreements.
Does the current program include Zero Tailings technology? No. Zero Tailings remains a separate potential future step and is not part of the three-stage metallurgical work.
The staged, third-party-funded approach reduces execution risk while generating data that could support broader adoption of bioleaching for historic tailings worldwide.
