Lithium Universe Ltd (ASX:LU7) Acquires Breakthrough Gold and Copper Extraction from E-Waste Technology

About this update from Lithium Universe Limited

Perth, Australia, May 27, 2026 - (ABN Newswire) - Lithium Universe Limited (ASX:LU7) (OTCMKTS:LUVSF) (HAM:KU00) is pleased to announce that it has secured an exclusive global licence from the University of Edinburgh for a breakthrough process to recover gold and copper from waste computers, phones, and circuit boards (e-waste). E-waste generation is estimated to be about 93.5 Mt by 2030 of which 80% ends up in landfill. Highlights - Acquired global rights to University of Edinburgh's gold and copper extraction hydro-met technology (Gold Copper Diamide Extraction GCDE process) - GCDE Technology selectively extracts gold and copper from electronic waste - Uses simple, recyclable organic compounds to selectively extract gold and copper - Ability to selectively extract gold and copper with minimal impurities - Advantages over conventional high temperature smelting - Devices, phones, laptops and printed circuit boards - E-waste generation estimated at 93.5 Mt by 2030 of which 80% ends up in landfill - Approx 200-350 grams of gold in one metric tonne of e-waste - Amount of gold in e-waste is 100 times higher than in natural gold ore - Gold content is worth US$46,320 pt e-waste (300g/t @ US$4,800 /oz) - Copper in e-waste ranges from 50-270 kg per tonne - Copper content is worth US$2,064 pt e-waste (160 kg/t @ US$12,900 /t) - Complements LU7's silver extraction technology from PV recycling Developed by the University of Edinburgh's School of Chemistry, supported by Edinburgh Innovations, the patented process exploits a simple, reusable organic diamide to selectively capture and precipitate gold from complex acidic solutions generated from circuit boards and electronic waste. Following gold recovery, copper is extracted using a dedicated copper-precipitating agent (pyrazine-2,3-dicarboxylic acid, PDCA), enabling the recovery of high-quality copper from the remaining acidic solution. Together, these two steps allow for the selective recovery of the two most valuable metals in e-waste without the need for high-temperature treatment or energy-intensive processes typically required in conventional smelting or pyrolysis methods. The technology is known as the Gold Copper Diamide Extraction (GCDE) process. While the sustainable recycling of these materials is complex and often uses environmentally unsustainable methods, the development of new hydrometallurgical processe...
