INDIGO ENGAGES INDUSTRY-LEADING DLE PROVIDER FOR INITIAL LITHIUM BRINE RECOVERY TESTS

Indigo Exploration Inc. has selected Sunresin New Materials to conduct initial direct lithium extraction (DLE) recovery tests for the company's petro-lithium brines. Approximately 150 litres of brine will be collected from each project area, namely the Fox Creek East and Fox Creek West, and shipped to Sunresin's facilities located in Xi'an, China, for recovery tests under the supervision of company representatives. Sunresin offers a proprietary, end-to-end solution for the processing of brine to finished products (lithium carbonate (Li2CO3) and lithium hydroxide (LiOH)) with over a decade of experience and successfully executed nine commercial DLE contracts representing over 73,000 tonnes of lithium carbonate equivalent. Due to unforeseen scheduling conflicts with the various contractors, the Fox Creek sampling program is now scheduled to commence June 26, 2023.

"With significant investments made into the field of direct lithium extraction, combined with the plethora of available off-the-shelf solutions in the marketplace, we are focusing our efforts on exploration and development without the added distraction of trying to reinvent a proprietary DLE solution," commented Paul Cowley, chief executive officer and director of Indigo Exploration. "Our in-house metallurgical advisory board has identified Sunresin as one of the leading end-to-end EPC (engineering, procurement and construction) providers in the market. In order to deliver the most representative results from their DLE process and expedite the advancement of our project timelines, we will be using a sizable 300-litre sample of brine collected from the Fox Creek project as opposed to a synthetic sample of a much smaller quantity. Our team believes this will provide us with the best-quality real-world data on the process and recovery characteristics."

About Indigo's metallurgical advisory board

Indigo Exploration is working with Dr. Gary Kordosky and Dr. David Dreisinger as advisers to advance the testing and development of direct lithium extraction (DLE) for its Alberta lithium brines. Dr. Kordosky worked throughout his career on solvent extraction technologies with Henkel, Cognis and BASF. He began to investigate lithium solvent extraction over 20 years ago and brings a deep experience in solvent extraction chemistry and industrial process design to help Indigo. Dr. Dreisinger is a professor and chair of hydrometallurgy at the University of British Columbia with general background in metal separation and recovery using ion exchange, solvent extraction, adsorption and membranes. Together with his students and industrial partners, he has researched various DLE technologies for more concentrated brine solutions such as those found in the salars of the South American lithium triangle.
