The technology utilises a proprietary multistaged process incorporating novel membrane technology and is based on proprietary IP, incorporating patents, expertise and know-how acquired over more than a decade of intense process development. Advantages of the aMES® technology include: • improvements in mineral recovery and product quality, • opportunity for substantial project capex & opex savings, • efficient use of energy and produces pure water as a by-product, and • improved project footprint and environmental sustainability. Ongoing collaboration with a number of brine project developers and operators has confirmed there are many applications where the aMES® technology has the potential to deliver substantial value by enhancing existing flowsheets, in order to improve overall project performance. aMES® Brine Processing Technology Key Industries (Applications) • Mining natural brine (salt lakes) • Solution mining brine (potash) • Refinery & industrial waste brine • Wastewater treatment brine Target Products (Produced) • Potash (MOP/SOP/KMS) • Lithium and magnesium salts • Range of byproducts (B, Br, Ca, Co, Cu, I, Na, Ni, REE, Si, Sr) • Reagents • Water Additional Information www.parkwayminerals.com.au/ames-technology iBC® Technology The integrated Brine Causticization, or iBC® is a patented process technology that simultaneously removes common impurities from waste brine streams and converts sodium carbonates and bicarbonates commonly found in coal seam gas (CSG) brines, into more soluble sodium hydroxide. As a result of the causticization step, the iBC® technology produces a purified brine suitable for downstream processing, including with the aMES® technology, for the production of various salt products and industrial-grade sodium hydroxide. iBC® Brine Pre-Treatment Technology Key Industries (Applications) • Oil & gas waste brine (CSG) • Wastewater treatment brine Target Products (Produced) • Sodium hydroxide concentrate Additional Information • Sodium chloride https://www.parkwayminerals.com.au/ibc-technology • Byproducts (Ca, Mg, Si) 23 February 2021 | ASX Announcement | 2 About Parkway Minerals In October 2019, Parkway Minerals (ASX: PWN) completed a transformational transaction by acquiring an Australian unlisted public company, Consolidated Potash Corporation (CPC).
