Vancouver, November 20, 2023 - Indigo Exploration Inc. (TSXV: IXI) (OTCQB: IXIXF) (FSE: INEN) (the "Company") is pleased to announce that a National Instrument 43-101 Technical Report titled "NI 43-101 Technical Report: Resource Assessment of the Fox Creek West Lithium Project in West Alberta, Canada for Indigo Exploration Inc. (As of October 1, 2023)" has been filed on SEDAR.

The report documents a maiden lithium brine resource estimate at its wholly owned Fox Creek West property in Alberta completed by Sproule Associates Limited ("Sproule"), as initially reported by way of the Company's news release dated October 4, 2023.

Key Highlights:

• 231,100 tonnes of LCE in the Inferred Mineral Resource category from two Devonian-aged formation aquifers; the Wabamun and Beaverhill Lake Group Formations.
• Fox Creek West Property has an estimated 3.8 billion barrels of brine, with lithium concentrations between 31mg/L to 93 mg/L and an estimated average lithium concentration of 72 mg/L.
• In comparison, Lithiumbank's Broadwalk Project 30 km away has an average grade of 68 gm/L.
• Indigo's total land position at Fox Creek West equals 55,103 hectares and is adjacent to Lithiumbank properties.
• Indigo intends to focus development on those areas of its asset base featuring the highest lithium concentrations in the Beaverhill Lake Group formations, which are expected to drive strong economic returns and robust cash flows.
