Indigo Engages Sproule for Maiden Lithium Brine Resource Estimation and Provides Market Update

September 6, 2023 - Vancouver, British Columbia. Indigo Exploration Inc. (the “Company”) (TSX-V: IXI, OTCQB:

IXIXF, FSE: INEN) 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 estima tes 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.”

About the Fox Creek Lithium Brine Projects

The Fox Creek Project s are located adjacent to active exploration and development work being undertaken by

Lithium Bank, namely their Boardwalk and Park Place projects . The Fox Creek Project s cover an area of 114,522

hectares and is comprised of the Fox Creek East (45,568 hectares), Fox Creek West (59,738 hectares) and Fox Creek

Central (9,216 hectares) areas. The Fox Creek West Project targets the Devonian -aged r eefs, including the

Wabamun and the Swan Hills Formation of the Beaverhill Lake Group, which has the highest consistent lithium

concentrations according to sampling data from the Alberta Geological Survey.
