BacTech Environmental Files National Patents for Zero TailingsTM Technology in Canada and United States BacTech Environmental Corporation announced the national patent filings of its proprietary Zero TailingsTM technology in both Canada and the United States. The filings, made April 14, 2026, follow the company's original international (PCT) patent application filed on April 7, 2025, and represent a major step in commercializing a process that the company believes will fundamentally change how the global mining industry manages waste. BacTech's Zero TailingsTM process is designed to eliminate this liability entirely. Zero TailingsTM combines BacTech's proven bioleaching technology with existing downstream processing technologies to put every element present in a tailing into solution -- and then recover each element as a saleable product. Applied to sulphide and iron tailings, the process produces four principal product streams: Magnetite - high-purity iron oxide supplied to the steel and pigment industries; Ammonium Sulphate Fertilizer a nitrogen-and-sulphur fertilizer suitable for broad agricultural markets; Critical Minerals recovered in elemental form to supply clean-energy and advanced-manufacturing supply chains; and Silica -- industrial-grade silicon dioxide for construction, electronics, and specialty chemical applications. Because the process is designed to extract a product from every element present in the tailing, there is no residual waste stream -- hence the name Zero TailingsTM. BacTech's Zero TailingsTM process produces ammonium sulphate a dual-nutrient fertilizer providing both nitrogen and sulphur -as a direct by-product of treating sulphide and iron tailings. Unlike conventional fertilizer production, which relies on natural gas feedstocks and long international supply chains, BacTech's ammonium sulphate is generated through a biological process applied to existing mining waste stockpiles. The result is a domestically producible, sustainably derived fertilizer that can be manufactured in Canada and the United States -- independent of the geopolitical supply disruptions currently driving global food security concerns. Ammonium sulphate produced through BacTech's bioleaching process is a biologically derived fertilizer, generated by naturally occurring bacteria rather than through energy-intensive conventional synthesis. This positions the product favourably with the growing segment of agricultural buyers and food producers seeking sustainable, traceable inputs -- and potentially opens pathways for premium pricing in specialty and certified sustainable markets. Canada and the United States represent two of the world's most significant mining jurisdictions, collectively hosting thousands of active and legacy tailings facilities. Both countries have enacted, or are advancing, regulatory frameworks that increase the financial burden on mine operators associated with tailings storage and long-term environmental monitoring. BacTech believes that Zero TailingsTM addresses these regulatory pressures directly by offering operators a path to full materials recovery and site remediation. The national filings also position BacTech ahead of growing investor and regulatory demand for ESG-compliant mining practices. With critical mineral security a priority for both governments, a process that recovers those minerals from existing waste streams -- rather than requiring new primary extraction -- aligns directly with federal supply-chain strategies on both sides of the border. Patent Timeline: April 7, 2025 -- Original international (PCT) patent application filed for Zero TailingsTM. April 14, 2026 -- National phase filings submitted in Canada and the United States.

BacTech Environmental Corporation Files Provisional Patent Application to Expand Its Zero-Waste Processing Technology Beyond Bioleaching BacTech Environmental Corporation announced that it has filed a provisional patent application to expand its zero- waste processing technology beyond bioleaching. This new application builds on a full patent application submitted in April, which focused on treating iron and acid streams from bioleaching. The Company considers this development to have the potential to improve mineral processing operations by enabling the recovery of materials from waste, which may contribute to more sustainable practices. Over the next year, BacTech will seek potential industry partners to test and develop this technology across different platforms, with the goal of moving toward a full patent. Acidic iron streams are a common by-product of mineral processing. These are usually treated to neutralize acidity, often creating waste sludge. BacTech's zero-waste method offers a new way to treat these streams by recovering valuable materials and turning iron and acid into marketable products. Instead of using traditional neutralizing materials, BacTech's patented process uses ammonia, which is gaining importance in the green economy. This method allows for the production of clean, usable iron and fertilizer products and helps recover other valuable, contained metals. Using ammonia requires smaller amounts of neutralizing agent and less infrastructure. BacTech's process also helps conserve water, preventing it from getting trapped in sludge. The treated water is cleaner and easier to manage according to environmental standards. This next generation of BacTech's zero-waste processing technology does not rely on bioleaching and is possibly suitable for a wide range of mineral processing applications aimed at recovering iron and acid from waste streams. The technology potentially can be retrofitted to various types of operations, including copper and nickel sulphide processing, nickel laterite processing, heap and dump leaching for base metal recovery, heavy mineral sands processing, phosphoric acid production, rare earth element leaching, manganese and uranium leaching, as well as refractory gold pressure oxidation and oxidative leach processes. The technology can also potentially treat ongoing acidic runoff from old mine sites. BacTech's method turns these waste streams into valuable products like iron and fertilizer, while also producing clean water. This is a major improvement over methods that result in waste that must be managed long-term. In addition, BacTech's innovation has the potential to unlock new heap leaching opportunities for low-grade metal recovery that were previously deemed uneconomical. Historically, such processes were inhibited by the generation of large volumes of acidic, iron-laden solutions that required costly neutralization with lime or limestone and extensive waste impoundment. This limitation has been especially problematic for the pre-treatment heap leaching of low-grade refractory gold ores prior to gold extraction, due to the prohibitive costs associated with managing soluble iron and acid using traditional reagents Finally, BacTech's approach opens the door to economically recovering metals from low-grade ores that were previously considered uneconomical. In the past, treatment was limited by the need to manage large volumes of acidic, iron-rich solutions. BacTech's technology reduces these challenges and makes it easier to recover metals from more sources. Announcement • May 25

BacTech Environmental Corporation Provides Follow-Up Update on Sudbury Pyrrhotite Tailings R&D Project BacTech Environmental Corporation has issued a follow-up update from its December press release on the pyrrhotite tailings bioleach initiative in Sudbury, Canada. MIRARCO Mining Innovation led by Dr. Nadia Mykytczuk have commissioned the bioleaching cascade reactor circuit. The MIRARCO bioleaching team, have completed 2 baseline campaigns to ensure that instrumentation, the solids suspensions, leaching kinetics, and solid/liquid handling are operating as designed. Final refinements are underway and full-scale campaigns will be possible in the coming weeks. As previously reported, BacTech is part of a consortium aiming to provide innovative solutions for remediating 80-100 million tonnes of pyrrhotite tailing deposited in and around Sudbury, Canada. Pyrrhotite ("Po") is a highly reactive iron sulfide mineral that reacts strongly when exposed to oxygen, releasing soluble acidic iron harmful to the environment. They also contain lower grade nickel and cobalt values. In addition to conducting the bioleach test work for pyrrhotite, considerable thought will be directed at planning for both the upstream (feed) and downstream process components. Up to 90% of pyrrhotite is made up of iron (55%) and sulphur (35%). The focus of the test work will be to determine whether there exist formulations for both elements that could be commercially sold as a by-product to enhance the overall economics of the project. BacTech plans to construct an owner-operated bioleaching facility in Tenguel, Ecuador, a region known for its association with arsenic in sulphide gold ore (Arsenopyrite). The company intends to build a 50 tpd bioleach plant capable of treating high gold/arsenic material. Such a plant, processing feed with 1.75 ounces of gold per tonne, similar to what local miners provide, would yield approximately 31,000 ounces per year. The modular plant designs allow for expansion without disrupting ongoing production. BacTech has also signed an agreement with the government for a Phase 2 plant that would add 150- 200 tpd of capacity, producing more than 100,000 ounces per annum. The area hosts over 100 small mines, and BacTech is actively exploring the possibility of establishing modern bioleaching facilities in other regions of Ecuador, Peru, and Colombia. The company aims to collaborate with national and local governments, non- governmental organizations (NGOs), and other stakeholders to fund these projects and ensure adherence to high environmental and ESG (Environmental, Social, and Governance) standards.

Bactech Environmental Corporation Provides Update on Sudbury Pyrrhotite Tailings R&D Project for Clean Recovery of Metals Team to Kick Off Detailed Bench-Scale Testing Program in January BacTech Environmental Corporation has issued an update on its proposed pyrrhotite bioleach R&D project in Sudbury, Canada. As previously reported, BacTech is part of a consortium aiming to provide innovative solutions for remediating 80-100 million tonnes of pyrrhotite tailings deposited in and around Sudbury. Pyrrhotite ("Po") is a highly reactive iron sulfide mineral that reacts strongly when exposed to oxygen, releasing soluble acidic iron harmful to the environment. Historically, predecessor companies such as INCO and Falconbridge separated pyrrhotite from the more valuable nickel cobalt pentlandite, depositing resulting pyrrhotite waste either underwater or under caps/covers to prevent oxidation. Despite being contained, natural bacteria can cause some degradation over the years. Currently, Vale and Glencore, continue managing these tailings to reduce their long-term liabilities. Dr. Nadia Mykytczuk, President and CEO of Mirarco, a leader in innovative solutions for the mining industry, confirmed that the continuous laboratory-scale bioleach pilot plant is undergoing pre-testing of equipment. This will lead to BacTech's technology being tested on a few kilograms a day basis starting in January 2024, with the program estimated to run approximately 6 months. Techno-Economic Feasibility Testing. The objective of the overall test is to determine if bioleaching can not only break down pyrrhotite to liberate small amounts of cobalt and nickel values as project revenue streams but also if other by-products from bioleach can be manipulated into intermediary products of value, creating additional revenue streams. Technically, the results will be crucial for BacTech in securing patent protection for this innovative process, representing the next step in advancing the provisional patent application already in place. Commercially, the results are vital for designing a fully integrated demonstration plant using commercial-scale equipment, proving the technoeconomics of the entire process and producing tonnage quantities of products for end-user testing. This would lead to the construction of a full-scale prototype production facility. Readying Proven Tech for Today's Economy. Over 20 years ago, BacTech conducted a pilot project in Australia (Radio Hill Mine), successfully bioleaching pyrrhotite to recover nickel and cobalt into a saleable mixed precipitate. However, economic viability was hindered by the need to dispose of benign waste from the bioleach process. Fast forward to the present, the total flowsheet concept has been redesigned, focusing on managing benign waste streams as a key process driver to enhance profitability. The combination of reducing the need for benign waste disposal facilities and diversifying revenue streams benefits project economics. Proven technologies can integrate with conventional bioleach processes to create saleable intermediary products from waste streams, reigniting research in this area. At today's nickel prices, the tails contain approximately $15 billion alone. These could be precipitated for sale, as demonstrated from BacTech's piloting experience in processing Radio Hill material in Australia. Finally, the clean siliceous waste from processing, making up about 15% of the original feed, can be used to produce construction materials using innovative proven geopolymer technology. Success factors for this program include co-production of metals and materials, demonstration of environmentally benign processing, and competitive economics in today's evolving market. BacTech anticipates providing results on an ongoing basis over the 6-month test program. Announcement • Nov 21
