Vancouver, British Columbia--(Newsfile Corp. - August 15, 2024) - Indigo Exploration Inc. (TSXV: IXI) (OTCQB: IXIXF) FSE: INEN) (the "Company") 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 km² area (the "Acquisition").

The Hot Property claims have seen extensive historical exploration dating back to the 1960's with over 200 holes drilled including near-surface intercepts of 1.83 metres of 1.1% U₃O₈ at a depth of 43.0 metres and 3.35 metres of 0.28% U₃O₈ 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% U₃O₈ at a depth of 43.0m and a second hole (H6-Zeb-44) encountered 3.35m of 0.28% U₃O₈ 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.
