BEYOND THE MIC – BacTech Bugs Eat Rocks Highlighting A Potential ~$30M Annual Opportunity

In a recent long form video interview with AGORACOM (see link at the end of this article), BacTech Environmental CEO Ross Orr made the case for what might be one of the most elegant solutions in mining: using naturally occurring bacteria to unlock metals that conventional processes can’t economically touch.

The company’s pitch is simple but striking. “Our bugs eat rocks,” Orr explained — a reference to bioleaching, a biological process that uses microorganisms to break down sulfide minerals and release the valuable metals trapped inside. It’s not new science, but BacTech has spent decades proving it works at commercial scale. Now, the company is positioning itself to build and operate its own facilities, capturing the full value chain rather than licensing the technology to others.

A Proven Technology With a Commercial Track Record

Bioleaching has been around since the mid-1980s, when Gold Fields of South Africa pioneered the first commercial plant. BacTech’s lineage traces back to research conducted at King’s College in London during the energy crisis, initially aimed at removing sulfur from coal. Australian researchers saw broader potential and brought the technology to Perth, where BacTech built its first commercial bioleach plant in 1994.

Since then, the company has designed and built four commercial-scale plants — in Australia (1994), Tasmania at Beaconsfield (1997, which ran for 15 years until the mine was depleted), and two in China (2001, expanded in 2008). The technology works by feeding sulfide concentrates — the material that contains the metals — into tanks where bacteria consume the sulfur, breaking down the rock and freeing gold, silver, and other metals for recovery.

What sets bioleaching apart is what it avoids: high heat, toxic chemicals, and the environmental liabilities that come with conventional smelting. The process produces ferric arsenate, a stable form of arsenic that the U.S. Environmental Protection Agency has approved as landfillable. That’s critical in regions where arsenic-rich concentrates are otherwise difficult or impossible to process cleanly.

“This is not our first rodeo,” Orr said. “We’ve been there, we’ve done it, and we’ve scoped out the Ecuador project to the point where we know pretty much what the capex exactly is.”

The Ecuador Opportunity: Serving 100 Small Mines With Material No One Else Wants

BacTech’s flagship project is a fully permitted, construction-ready bioleach processing plant in Tenguel, Ecuador, strategically located near the Ponce Enriquez mining district. The region is home to over 100 small-scale mines producing high-arsenic, high-gold concentrates — material that virtually no one else will touch at fair prices.

The problem for these miners is stark. Chinese buyers currently dominate the market for arsenopyrite concentrates (a sulfide mineral containing arsenic, iron, and often gold). But in 2021, China imposed a 13% import tax on high-arsenic concentrates, and buyers passed that cost directly to the miners. Today, Ecuadorian miners receive roughly 50 cents on the dollar for the gold contained in their concentrates.

BacTech’s solution is to process the material in-country, pay the miners more, and eliminate the need to ship concentrates halfway around the world. The company completed a bankable feasibility study that modeled the project using conservative assumptions: $1,600 per ounce gold and $18 per ounce silver. Even at those prices, the study projected $22 million in capex, annual production of approximately 30,000 ounces of gold, and over $11 million in pre-tax annual profit.

With gold now trading above $4,600 per ounce, the economics look significantly stronger. Orr noted that at current gold prices, projected after-tax earnings could exceed $30 million per year for Phase 1 alone.

The project also benefits from an International Protection Agreement (IPA) with the Ecuadorian government, which grants BacTech a 12-year tax holiday and provides for international arbitration in the event of disputes. Government support has been strong, Orr explained, in part because BacTech’s process is cleaner than conventional methods and provides local employment and better compensation for regional miners.

“The Indigenous people in Ecuador are not big fans of mining,” Orr said. “By introducing a technology that is going to do it cleaner than what’s being done right now, we’re bringing something to the table that the government values.”

Phase 2 of the Tenguel project, which BacTech is committed to building under the IPA, would scale throughput from 50 tonnes per day to 250 tonnes per day — enough to handle the entire output of the Ponce Enriquez district. At that scale, the company projects annual production could reach 125,000 ounces of gold, generating substantial cash flow.

Beyond Gold: The Zero Tailings Platform

While the Ecuador project focuses on gold recovery from arsenopyrite concentrates, BacTech has developed a second platform that could have even broader applications: a patented Zero Tailings process that converts mine waste into multiple saleable products.

Mine tailings — the material left over after metals are extracted — are a massive global problem. An estimated 80 billion tonnes of tailings sit on surface worldwide, and the mining industry adds approximately 10 billion tonnes per year. These tailings often contain residual sulfides that oxidize over time, generating sulfuric acid that can leach into waterways and carry heavy metals with it. Tailings dam failures, like the catastrophic breach at Mount Polley in Canada and the Brumadinho disaster in Brazil, have caused loss of life and billions in environmental damage.

BacTech’s Zero Tailings process uses bioleaching to extract the residual metals from tailings while simultaneously producing high-purity magnetite iron (for steel production), ammonium sulphate fertilizer (an organic agricultural product), and critical minerals like nickel, copper, and cobalt. What’s left behind is inert silica sand that can be used for paste backfill or construction materials.

The process has been piloted in Sudbury, Canada, in partnership with MIRARCO Mining Innovation and Vale, one of the world’s largest mining companies. Vale provided pyrrhotite tailings for testing — a volatile iron-sulfide mineral that oxidizes rapidly and has historically been discarded as waste.

Orr emphasized that approximately 75% of the revenue from the Zero Tailings process comes from the iron and fertilizer byproducts, not the base metals. That diversification makes the economics far more resilient to commodity price swings and opens up applications across a wide range of mining operations.

“Imagine having your own internal fertilizer production,” Orr said. “Canada imports something like $150 million a year of organic fertilizer, mostly from the Far East. This is all about uncoupling yourself and your dependence on Chinese producers, much like we’re doing in critical minerals.”

The technology could also address a major financial burden for mining companies: the bonding requirements associated with tailings storage. By eliminating tailings and turning waste into revenue, companies could potentially free up hundreds of millions of dollars in balance sheet liabilities.

Licensing Strategy and Market Validation

BacTech does not plan to build and operate Zero Tailings facilities on its own balance sheet. Instead, the company intends to license the technology on a regional or country-by-country basis, collecting licensing fees and long-term royalties.

“We can’t do that on our balance sheet,” Orr said. “When there’s 80 billion tons of tailings sitting on surface globally, this is something that needs to be rolled out quickly.”

The company is in discussions with major mining companies and government entities. Following the recent PDAC mining conference in Toronto, BacTech signed multiple non-disclosure agreements with interested parties. Orr noted that the response has been strong, particularly from companies sitting on legacy tailings deposits that represent both environmental liabilities and stranded value.

In 2026, BacTech expects to advance toward building a demonstration plant, which Orr estimated could cost $40 to $50 million. That plant would not generate meaningful economic returns on its own but would serve as proof of concept at commercial scale, de-risking the technology for larger rollouts.

The company is also exploring partnerships with global engineering firms that could deploy the technology across multiple jurisdictions.

Financing: The Challenge and the Opportunity

When asked about risks, Orr was candid. The biggest challenge facing BacTech is securing financing for the Tenguel project. Unlike traditional mining companies, BacTech does not own an ore deposit, which eliminates the possibility of securing financing from royalty or streaming companies that require an asset to seize in the event of default.

“What am I going to do with a bioleach plant if you can’t make it work?” Orr recalled one financier asking. “I can sell it for scrap, but it’s going to be nowhere near $22 million.”

Additionally, Ecuador’s country risk — while improving — remains a concern for some institutional investors. Orr emphasized that he travels to the site regularly and has never encountered safety issues, and that the project has overwhelming local support. Employees currently working on the 100-acre Tenguel property (which includes a cocoa plantation) stand to see their annual incomes rise from roughly $2,000 per year to $60,000 per year once the plant is operational, thanks to a government-mandated 15% profit-sharing program.

Despite the financing challenges, Orr expressed confidence that a deal is within reach. The company is in active discussions with multiple parties, and recent activity suggests interest is building.

“I think we’re getting closer,” Orr said. “It may be a deal that’s not related to Ecuador at all. It might be something brand new. But all of them are situations where people are in production or near to production, so it’s not like it’s a five-year project.”

A Pipeline Beyond Tenguel

Orr described the Tenguel project as the first domino in a longer strategic rollout. Behind it are potential projects in Peru (both north and south), Chile, and even Canada, particularly in regions like Timmins and Val-d’Or, where arsenopyrite tailings and deposits remain untapped due to processing challenges.

When pressed on a five-year forecast, Orr recalled an internal projection that envisioned building one plant per year, eventually reaching combined annual production of 350,000 ounces of gold — worth over $1 billion at current prices. Net margins, he noted, could range around 20%, depending on jurisdiction and tax treatment.

“When you can sell something this small for $4,600, it doesn’t take you long to build up the revenue line,” he said.

PDAC Response and Near-Term Catalysts

Following the March 2026 PDAC conference, Orr reported strong interest from both major mining companies and government-backed entities. The company signed multiple NDAs and is advancing discussions around potential partnerships, licensing deals, and project collaborations.

While much of the pipeline remains under wraps due to confidentiality, Orr suggested that 2026 could bring material developments — though he was careful to avoid specifics.

“There’s so much stuff going on in the background that you can’t talk about until you actually ink something,” he said. “If the dominoes start to fall, we’re going to be busier than a one-armed paper hanger.”

Conclusion

In the interview, BacTech CEO Ross Orr discussed the company’s decades of commercial bioleaching experience and its strategy to build and operate its first own-account facility in Ecuador. He outlined the Tenguel project’s economics at current gold prices, the company’s Zero Tailings platform for critical minerals recovery and tailings remediation, and the strategic pipeline of potential projects across multiple jurisdictions. Orr acknowledged that securing financing remains the primary near-term challenge, while expressing confidence in the company’s technology, government support in Ecuador, and growing interest from major industry players following recent conference activity.
