INDIGO EXPLORATION INC. ANNOUNCES NAME CHANGE TO NOBLE PLAINS URANIUM CORP.

Indigo Exploration Inc. will be changing its name to Noble Plains Uranium Corp., a step that reflects the company's strategic focus on uranium exploration and development in the United States. This transition marks a significant step forward in aligning the company's identity with its renewed focus on advancing a growing portfolio of uranium assets aimed at fuelling the nuclear renaissance from America's uranium heartland through the responsible development of critical-mineral resources.

Paul Cowley, chief executive officer, stated: "This name change represents more than a rebrand -- it signals the start of a new chapter for our company. As Noble Plains Uranium, we are positioning ourselves to play a vital role in the resurgence of domestic uranium production, with a clear vision to advance strategic, high-impact projects in the U.S."

It is anticipated that the TSX Venture Exchange will issue a bulletin confirming that the company's common shares will commence trading under the name Noble Plains Uranium on May 22, 2025, under the new trading symbol NOBL. On the effective date, the new Cusip number of the company's common shares will be 65510H108 and the new international securities identification number will be CA65510H1082.

The name change does not involve a consolidation of the company's share capital, and as such, shareholders will not be required to exchange their existing share certificates for new ones. The name change will not affect the company's share structure or the rights of the company's shareholders, and no action will be required to be taken by shareholders with respect to the name change. All currently outstanding share and warrant certificates will continue to be valid under the new name.

The name change was approved by the company's board of directors, in accordance with the company's articles and the Business Corporations Act (British Columbia).

We seek Safe Harbor.
