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.

New minor risk - Shareholder dilution The company's shareholders have been diluted in the past year. Increase in shares outstanding: 23% This is considered a minor risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-CA$1.2m free cash flow). Share price has been highly volatile over the past 3 months (22% average weekly change). Negative equity (-CA$3.1m). Earnings have declined by 15% per year over the past 5 years. Revenue is less than US$1m. Market cap is less than US$10m (CA$6.10m market cap, or US$4.40m). Minor Risk Shareholders have been diluted in the past year (23% increase in shares outstanding).

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. Aankondiging • 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. Aankondiging • Nov 21

BacTech Environmental Corporation Confirms Gold and Copper Concentrate Potential in Peru for Bioleaching BacTech Environmental Corporation announced its bioleaching project interests in Peru will advance, focusing on gold and copper concentrates and potential metal recovery efforts. Having developed relationships with a number of artisanal miners and processors throughout the Trujillo area, BacTech has made arrangements to collect seven 15kg concentrate samples during the next two-to-three months from selected producers and processors. Global mining executive and technical advisor Oscar A. Alvarado Sr. will continue on as project lead. When ready, the samples will be shipped to ALS Laboratories facilities in Perth, Australia and subjected to bioleach testing under the guidance of Dr. Paul Miller. BacTech has no ownership in any of the mines where concentrates are being sourced. Similar to the model in place for the Company's commercial interests in Ecuador, BacTech has been meeting with producers who are looking to maximize returns for their concentrates, knowing that a safe and profitable processing solution to treat high arsenic concentrates in the Trujillo area is being considered. BacTech believes a bio-oxidation plant would support local economic development with the benefit of knowing that the processing of toxic materials would be dealt with in a sustainable manner. Miners across South America have been affected by an October 1, 2021 Chinese government- directed import tax of 13% placed on arsenic gold concentrates coming into the country for processing. This action has resulted in price slashing scenarios in which the miners are paid approximately 50% of the gold value delivered. Penalties escalate further with contained arsenic levels above the 10% level. In one illustrative meeting, BacTech was shown material from three different areas of a single mine each selectively mined in an effort to produce lower arsenic values for Chinese buyers. All sample materials contained copper, gold and silver as recoverable metals, yet prices being paid all fell considerably short of BacTech's Fair Market Value estimates: Sample 1 - FMV /$750 per ton; Price Realized /$270 per ton; Sample 2 - FMV /$650 per ton; Price Realized /$200 per ton; Sample 3 - FMV /$500 per ton; Price Realized /$80 per ton. Important to note, BacTech has previous experience working with chalcopyrite having collaborated with Industrias Penoles, S.A.B. (Q: IPOAF) on a bioleaching R&D project at its research park in Monterrey, Mexico a number of years ago. At the time, Penoles committed $5 million to build a demonstration plant to investigate the use of bioleaching on dirty chalcopyrite copper concentrates. Copper recovery using bioleaching /solvent extraction /electrowinning technology was used to produce 99.99% pure copper plate. Aankondiging • Sep 24

BacTech Environmental Corporation Announces Successful TCPL Testing Results, Confirms Long-Term Environmental Stability of Ferric Arsenate Precipitate as Ecuador Gold Project Advances BacTech Environmental Corporation announced final bioleaching test results showing the successful neutralization of bio-oxidation liquors and TCLP stability testing of ferric arsenate precipitates. Four neutralization tests were performed on two final bio-oxidation liquors from the Ecuadorian commercial bioleach testing program, confirming that an environmentally stable ferric arsenate precipitate could be produced. The neutralization process, where limestone is added and calibrated to raise the pH of the bioleach liquor to facilitate the precipitation of the ferric arsenate, conclusively demonstrated that the precipitate passes the TCLP (Toxicity Characteristic Leaching Procedure) requirements for stability set out by the U.S. Environmental Protection Agency ("EPA"). Duplicate neutralization tests were performed on each liquor, using both lime and limestone as the neutralization reagent. Neutralization was conducted in an agitated aerated reactor over a six-hour contact time as per commercial protocol for bio-oxidation plants. Test results showed that the amount of arsenic remaining in solution was 0.5ppm, while the quantity of iron was minimal (between 3ppm to 18ppm due to the presence of residual ferrous iron). This analysis confirms that the neutralization operation will produce a neutral clean water as a by- product that is suitable for recycling in the process. This finding is significant for BacTech as it will reduce the quantity of fresh water required on site. The Toxicity Characteristic Leach Procedure (TCLP) test is a procedure to evaluate the long - term stability of the arsenic in the precipitate produced by the neutralization process. It is a favoured US EPA method for characterizing waste as either hazardous or non-hazardous as defined in the Code of Federal Regulations; RCRA 40 CFR Part 261. The test involves efforts to re-leach the arsenic into an acidic solution using a standardized protocol and aims to simulate long term conditions within a landfill. BacTech is planning to build its new owner-operated bioleaching facility in Ponce Enriquez, Ecuador, in a region where arsenic is well-known to exist in the gold ore. The Company's plan is to build a 50 tpd bioleach plant capable of treating high gold/arsenic material. A 50 tpd plant, processing 1.5 ounces of gold per tonne of feed, similar to feeds available to the company, would produce approximately 26,000 ounces per year. Plant designs are modular and can be expanded without affecting ongoing production. BacTech continues to investigate the prospects of establishing additional modern mining operations across other areas of Ecuador, Peru, Colombia, and Central America. Where possible, the company will partner with national and local governments, non-governmental organizations (NGOs), and others to assist with the funding of these projects. Aankondiging • Jun 25
BacTech Environmental Corporation Announces Formal Bioleach Test Work for the Company's Ponce Enriquez Bioleaching Project is Now Complete BacTech Environmental Corporation announced that all formal bioleach test work for the company's Ponce Enriquez bioleaching project is now complete. BacTech will deliver final testing results and analysis when received by third-party testing provider ALS Laboratories. Bio-Oxidation Kinetics: Bioleach test work on material collected from small mine producers in Ponce Enriquez, Ecuador, previously assayed to confirm positive magnitudes of gold, was completed on June 23rd, 2021. While assay results from oxidized solids are pending to confirm the extents of oxidation achieved, the results from solution assays taken throughout the testing campaign indicate good kinetics with complete solubility of arsenic from all samples tested complimented by a high level of iron dissolution from refractory mineralization. This is a positive indicator in being able to obtain a high gold recovery from downstream processing. No unusual phenomenon was encountered during the testing compared to other feedstocks which have been previously tested and resulted in a successful commercial plant. These results are particularly encouraging, given the fact that some of the feedstocks tested were cyanide tails with high arsenic contents which are recognized as more difficult to treat due to toxicity phenomenon. A specialized pre-washing process was used to mitigate the toxicity effects of any residual cyanide species present in these feedstocks on the bio-oxidation process. A further positive attribute is that due to the low amount of inert siliceous gangue present in the feedstocks, a high weight loss was noted in the bio-oxidation testing. This has positive process implications in reducing the size of equipment required for downstream gold recovery and hence capital and operating costs. Gold Recovery: Cyanidation work will be conducted on the bio-oxidized residues at an independent lab to quantify the amount of gold that was liberated using bioleaching. Previous diagnostic test results received from ALS Laboratories on 20 April showed that if the feedstocks are oxidized to
extinction, then 99% of the gold can be recovered. Bioleach Liquor Neutralization: This study will validate model predictions for reagent requirements of limestone (CaCO) and other reagents. Limestone (or lime) will be added to the post bioleach solution to raise the pH enabling precipitation of the iron and arsenic to form a stable ferric arsenate precipitate recognized by the USEPA and similar bodies as being environmentally benign and suitable for disposal. This test work will also produce a clean water for recycling to the process and the final solutions from neutralization will be assayed to ensure compliance for re-use. Toxicity characteristic leach procedures (TCLP) will be undertaken by an independent qualified laboratory on the ferric arsenate test precipitates to confirm that they are benign and meet environmental regulatory requirements for approval and process permitting.
Environmental Testing: This testing will focus on the arsenic precipitate produced from the neutralization process to confirm resulting ferric arsenate is in compliance with the Toxicity Characteristic Leaching Procedure ("TCLP") standards and the US EPA's standards for deposition of waste materials.
BacTech intends to transform harmful contaminants into benign EPA-approved products and the results from this test work will contribute to environmental approval for the project and process permitting. Ponce Enriquez Bioleaching Project: BacTech is pursuing a new owner-operated bioleaching facility in Ponce Enriquez, Ecuador where arsenic is well-known to exist alongside gold mining.

BacTech Environmental Corporation Receives Assay Results of Up to 2.24 Oz Gold Per Tonne BacTech Environmental Corporation announced the assay results for the six concentrate samples collected from small mine producers in Ponce Enriquez, Ecuador. The area is known for its production of gold rich arsenopyrite material. The assay work was conducted by ALS Laboratories in Vancouver, Canada. Sample #2 reported copper values of 9.64%. With the recent resurgence in the price of copper an investigation will be conducted to see if a copper by-product can be produced for sale. The most likely conclusion, with respect to the presence of copper, would be that the material is enargite. BacTech is considering shipping this material to Laurentian University to conduct a desk top study similar to the test program conducted on the original mineral samples from Ecuador. The test work would determine the ability of bioleaching to produce both gold and copper metal. An interesting aspect of the mineral processing in Ponce Enriquez has been identified by BacTech's Bernardo Brito. Mr. Brito has been in active discussions with various mines sourcing concentrate for test work. A common theme of processing has emerged with respect to suppressing arsenic in the floating of concentrates to reduce the arsenic content and the associated penalties imposed by Asian smelters. This has the consequence of also suppressing gold recovery as the amount of gold that reports to the concentrate is below what normal flotation methods would provide. BacTech's approach of not charging penalties on arsenic will allow the miner to produce a higher grade of gold concentrate. BacTech's bioleach technology is highly amenable to treating concentrates with very high arsenic contents and therefore does not have the same constraint as producing concentrates for smelting. The bioleach test work to be conducted in Perth will involve three separate tests. Two samples of the material that were assayed in Vancouver at ALS had already been contacted with cyanide by the miner to recover the gold that was not refractory. As high levels of residual cyanide compounds can be detrimental to the bacteria, these two sample will be subjected to a simple pre-treatment process before any bioleach test work is started. The third test will use a composite of samples which have not previously been subjected to cyanidation. From the reported samples it is recommended that bioleach test work be undertaken on samples #1, #3 and #5. According to assay records of the mine the magnitude of gold in sample #4 should be much higher. Investigations will be pursued to evaluate the reasons for this anomaly. With respect to other projects being pursued by BacTech, the Company is still awaiting the reopening of travel within Colombia . When access is approved BacTech and MetalTec will engage a third-party for sampling of the gold/platinum tailings that was announced by BacTech on August 10, 2020. In summary, BacTech is investigating the prospects of a build/own/operate bioleach facility to be based in Ponce Enriquez, Ecuador. The selection of Ponce Enriquez is driven by the extremely high levels of arsenic that is associated with gold in the +90 small mines in the area which attract high penalties in smelting . Presently, the miners are forced to sell their production at reduced prices to Asian buyers due to the high arsenic values in the concentrates and accept lower financial returns. BacTech proposes to pay better prices for the miners' material, by eliminating penalties for arsenic, and process higher grade gold to reduce overall refining costs. This concept can be repeated in areas of Peru, Colombia and Central America where arsenic is known to exist alongside gold mining. Aankondiging • Sep 23
BacTech Environmental Ships Concentrate Samples for Assay Ranging from 20 to 60 Grams Gold Per Tonne BacTech Environmental Corporation provided the following update on its Ponce Enriquez, Ecuador project. As previously reported, a total of 6, 10-kilogram (22 lbs) concentrate samples were collected from 6 different processing plants around Ponce Enriquez. There are over 90 different processors in the area producing anywhere from 1 to over 20 tonnes per day of concentrate that contain high gold and arsenic values. The output is generated by both mine owners as well as small miners who deliver mineralized material for processing. The gold grades of the 6 concentrate samples, as stated by the processors, ranged between 20 (0.64 opt)and 60 (2 opt) grams per tonne with arsenic values above 10% per tonne. From the 6 collected concentrate samples, 3 arsenical refractory gold samples will be prepared and subjected to bioleaching and cyanidation testing. Two of the concentrate samples are Carbon-In-Pulp ("CIP") residues and the third is a blend of flotation concentrates that have not been previously contacted with cyanide. Regrinding and washing of the cyanide residues will be undertaken to remove traces of cyanates before bioleach testing and to avoid toxicity issues. Given the presence of high levels of arsenic, the producers in Ponce Enriquez are subjected to a heavy discount in the prices they receive for their gold. A survey conducted by the Company would suggest that producers are paid approximately 65% of the gold value in the concentrate. The majority of the discounted high- grade gold/arsenic concentrates are bought by Asian smelters or roasters and shipped there for processing. For comparison, processors of oxide material in Peru pay roughly 90% of the contained gold value. BacTech’s plan is to build a 50 tpd bioleach plant capable of treating high gold/arsenic material in Ponce Enriquez. A 50 tpd plant, processing 1.5 ounces of gold per tonne of feed, would produce approximately 26,000 ounces per year. The plants are modular and can be expanded without affecting the ongoing production.
