Indigo Engages Industry-Leading DLE Provider for Initial Lithium Brine Recovery Tests
Indigo Engages Industry-Leading DLE Provider for Initial Lithium Brine Recovery Tests
June 20, 2023 - Vancouver, British Columbia. Indigo Exploration Inc. (the “Company”) (TSX-V: IXI, OTCQB: IXIXF,
FSE: INEN) is pleased to announce the selection of Sunresin New Materials (“ Sunresin”) 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 (collectively the “Fox Creek
Project”), 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 lit hium carbonate
equivalent. Due to unforeseen scheduling conflicts with the various contractors, the Fox Creek sampling program
is now scheduled to commence June 26.
“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, CEO 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 Proj ect 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.”

Sunresin New Materials Co., Ltd. is a key player in the DLE (Direct Lithium Extraction) market, focusing on providing
advanced solutions for lithium extraction and purification. They specialize in the development of high-performance
ion exchange resins tailored fo r DLE applications. These resins efficiently extract lithium ions from brine or other
sources, offering a sustainable and cost -effective alternative to traditional mining and evaporation methods.
Sunresin's DLE resins are known for their outstanding performance, stability, and durability, making them ideal for
large-scale lithium extraction projects. The company collaborates with industry partners to customize solutions and
optimize the efficiency of the extraction process, catering to the increasing demand for lithium in electric vehicle
batteries and renewable energy storage systems.
Sunresin has three commercial deployments including Lanke Lithium (20,000 tpa of LCE), Zangge Lithium (20,000
tpa of LCE) and Jintai Lithium (7,000 tpa of LCE), in addition to numerous projects and partnerships at the
evaluation, pilot and development-stage in South America, Australia, North America, and Asia.
About Indigo’s Metallurgical Advisory Board
Indigo Exploration is working with Dr.’s Gary Kordosky and David Dreisinger as Advisors 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 corporation. 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 Co lumbia 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 sol utions such as those found in the salars of the South
American lithium triangle.
