Vancouver, British Columbia--(Newsfile Corp. - September 6, 2023) - Indigo Exploration Inc. (TSXV: IXI) (OTCQB: IXIXF) (FSE: INEN) (the "Company") is pleased to announce it has awarded Sproule Associates Limited ("Sproule") the contract to prepare a maiden resource estimate for the Company's Fox Creek West lithium brine project in central Alberta. With over 70 years of operating history in over 90 countries, Sproule has established a reputation as a leader in the energy space. Within the resource estimation and certification space, Sproule completes over 250 evaluations annually in over 50 countries which recently includes the petrolithium brine resources for the Rainbow Lake project in Alberta and the Kindersley project in Saskatchewan.

The Company would also like to highlight the recent milestone advancements from neighbouring E3 Lithium Ltd. ("E3") an emerging lithium developer in Alberta which announced last week the commencement of operation of its Direct Lithium Extraction (DLE) pilot plant. E3's plant represents the first commercial operation of a pilot plant within the Western Canadian Sedimentary Basin ("WCSB") targeting petrolithium brines from the same or similar aquafer reservoirs as contained within Indigo's projects. Indigo's Leduc-Legal project adjoins some of E3's Alberta properties targeting the same world-class Leduc Aquifer.

"The engagement of Sproule to complete our first maiden resource estimate represents the culmination of activities since last October when the Company shifted its focus to the growing lithium market," commented Paul Cowley, President & CEO of Indigo Exploration. "The resource estimate for Fox Creek West represents only the first of many maiden resource estimates we anticipate delivering and only the beginning of demonstrating the world class potential of these projects to fill the overwhelming lithium supply imbalance. E3's efforts in demonstrating the commercial potential of the DLE application to petrolithium brine projects in Alberta paves the way for other players in the industry to unlock the value of this vast resource."
