Indigo Reports Transaction Closing on Hot Uranium Project, Wyoming

Vancouver, BC, August 15, 2024 – Indigo Exploration Inc. (the “Company”) (TSX -V: IXI, OTCQB:

IXIXF, FSE: INEN) is pleased to announce that further to its news release dated July 9, 2024, it has received

TSX Venture Exchange (“ TSXV”) approval for and completed the acquisition of a 100% interest in the

Hot Property (the “Property”), a highly prospective uranium project located in the past producing Shirley

Basin of Wyoming, comprised of 71 unpatented mineral claims covering a 5.75 km 2 area (the

“Acquisition”).

The Hot Property claims have seen extensive historical exploration dating back to the 1960s with over 200

holes drilled including near-surface intercepts of 1.83 metres of 1.1% U 3O8 at a depth of 43.0 metres and

3.35 metres of 0.28% U 3O8 at a depth of 26.8 metres. The Project is located adjacent to Uranium Energy

Corp.’s (UEC -NYSE) Shirley Basin project, Ur -Energy Inc.’s (URG -NYSE) Shirley Basin mine, and

Nuclear Fuels Inc.’s (NF-CSE) Bobcat Uranium Project. Ur-Energy’s Shirley Basin project hosts an NI 43-

101 Measured and Indicated Resource of 8.8 Mlb U3O8 grading 0.23%1 and is currently under construction2.

The Shirley Basin of Wyoming

Wyoming represents the largest uranium producing state and contains the greatest uranium ore reserves

within the United States. The Shirley Basin located 40 miles southwest of Casper, Wyoming, produced

over 51 million pounds of U3O8 from 1960 to 1992 at an average grade of 0.22% U3O8. The Shirley Basin

mines closed not for a lack of resource but due to lower uranium prices. The importance and relevance of

the Shirley Basin today is reflected in production resurgence with Ur-Energy’s production plans.

Hot Property

The Hot Property is strategically located just 800m east (0.5 mile) of an historic production area and 1.8km

(1.1 miles) from Ur-Energy’s uranium resource. Indigo uncovered 202 drill logs from public records from

holes drilled in the 1950’s on ground now covered by the Hot Property. One intercept (H1 -Zeb-44)

encountered 1.83m of 1.1% U 3O8 at a depth of 43.0m and a second hole (H6 -Zeb-44) encountered 3.35m

of 0.28% U 3O8 at a depth of 26.8m. Of the 202 holes, approximately 46% intercepted shallow uranium

mineralization. Depth to mineralization ranges from 3m to 130m but average 46m deep in Eocene-aged

Wind River Formation, the uranium host unit in the Shirley Basin. The Hot Property is particularly

promising as one third of the mineralized holes on the property have two or more uranium intercepts.

Company geologists have designed an initial 50-hole reverse circulation drill program and has submitted a

Notice of Intent permit application to the BLM for permitting of the RC drill program.
