(the "Company" or "Sulnox")

Patents for Chile, Peru, Israel

(Aquis Stock Exchange: SNOX, OTCQX: SNOXF)

Sulnox, the greentech company delivering lower fuel costs and emissions with zero capex, is pleased to announce that it has secured three additional patents in the key target markets of Chile, Peru and Israel.

All three patents for emulsification cover Sulnox Eco™ Fuel Conditioners which enhance all diesel, petrol/gasoline and biofuels, and marine fuels including Marine Gas Oil (MGO) and Marine Diesel Oil (MDO), Very and Ultra Low Sulphur Fuel Oils (VLSFO/ULSFO) and HSFO. Sulnox has been granted more than 100 patents to date in major markets globally, protecting the company's processes for emulsification and fuel oil reclamation, while supporting its revenue development.

Chile represents a major long-term opportunity for Sulnox in the mining sector. The country is the world's largest copper producer and one of Latin America's most advanced and export-oriented economies. Mining accounts for approximately 10-14% of GDP and over half of national exports, driving intensive diesel usage across large-scale open-pit operations, high-capacity haulage fleets, and energy-demanding processing facilities. These operations are served by well-developed logistics networks, including long-distance road freight and dedicated rail links connecting inland mines to major Pacific ports such as Port of Antofagasta and Port of Valparaíso.  Chile's reliance on maritime trade reinforces consistent demand for marine fuels and heavy transport solutions. At the same time, the country has one of the most progressive decarbonisation agendas in the region, targeting carbon neutrality by 2050 and actively promoting energy efficiency and emissions reductions across mining and transport.

Peru, a contiguous neighbour of Chile, extends the mining opportunity in a country where precious metals contribute around 8-9% of GDP and more than 60% of exports. Fuel-intensive supply chains depend on maritime routes via key ports such as Callao, while heavy-duty trucking and rail dominate inland logistics, sustaining demand for diesel. Unsurprisingly, transport emissions form a significant share of Peru's greenhouse gas profile and its government's growing alignment with international decarbonisation goals. The country has an additional environmental imperative to help protect one of the most biodiverse regions on Earth, not only from Carbon Dioxide, but from pollutants such as particulate matter and sulphur oxide which cause corrosion, soiling and structural damage to historical monuments of global importance.

By contrast, Israel represents a strategically significant patent for Sulnox as the Company expands across the Eastern Mediterranean and the Suez Canal corridor, supported by regional links to markets such as Jordan and Saudi Arabia where patents are also in place. The country's heavy reliance on maritime trade, handling around 99% of imports and exports via key ports including Port of Haifa and Port of Ashdod, underpins a substantial marine fuel and logistics market and strengthens the relevance of Sulnox technology to shipping and heavy transport. This opportunity is further aligned with Israel's ambitious decarbonisation strategy, targeting a 27% reduction in greenhouse gas emissions by 2030 and 85% by 2050. Transport, presently accounting for approximately a quarter of emissions, has been identified as a key focus area, supporting demand for transitional solutions that reduce fuel consumption and emissions while complementing the shift towards electrification and alternative energy.

Commenting on these three important new patents, Ben Richardson, CEO of Sulnox, said:

"Securing patents in Chile, Peru and Israel demonstrates the momentum of growing our intellectual portfolio, while supporting major opportunities in two very different continents. These markets combine high-volume maritime trade and other traditionally heavy users of fossil fuels with growing regulatory and commercial focus on emissions reduction. By enhancing fuel stability, combustion efficiency, and operational reliability, our solutions can help industrial operators across these regions to meet environmental goals and lower costs, providing a practical, scalable solution as these three economies transition toward cleaner energy sources."
