Highlights

• Stardust acquires a 1.5% net smelter return royalty on each of its Kirkland West and Omega projects for $1.0 million.

• Acquisition internalizes a meaningful encumbrance on future production and directly enhances the future economics of both projects for Stardust shareholders.

• Kirkland West is immediately adjacent to Agnico Eagle’s Macassa Mine, Canada’s highest-grade gold mine.

• Omega lies directly south of Agnico Eagle’s Upper Beaver deposit and immediately west of Cadillac Mines’ (formerly Gold Candle) Kerr-Addison Mine.

Stardust Metal Corp. (CSE: ZIGY) is pleased to announce that it has exercised its option to acquire a 1.5% net smelter return royalty on each of its Kirkland West and Omega projects from Harbour Royalty Corp. for total consideration of $1,000,000.

The royalty acquisition applies to two of the Company’s core assets in the prolific Kirkland Lake Gold Camp of northeastern Ontario. Kirkland West comprises approximately 4,300 hectares immediately adjacent to Agnico Eagle’s Macassa Mine, Canada’s highest-grade gold mine. Omega, a past-producing mine hosting a historical gold resource on the Larder Lake–Cadillac Break, lies directly south of Agnico Eagle’s Upper Beaver deposit and immediately west of the Kerr-Addison Mine, owned by Cadillac Mines (formerly Gold Candle), Figure 1. Both projects sit in the heart of a camp that has produced more than 40 million ounces of gold and remains dominated by major producers actively seeking new sources of ore.

The option was exercised on June 12, 2026 pursuant to the terms of a royalty agreement originally entered into in 2019 and subsequently amended in 2024. The Company has delivered the required notice and consideration, and the transaction has been completed in accordance with the terms of the agreement.

Janet Meiklejohn, VP Corporate Development of Stardust, commented:

“Acquiring a 1.5% royalty on both Kirkland West and Omega for $1.0 million is one of the most accretive investments we can make on behalf of shareholders. With Kirkland West sitting on the doorstep of Canada’s highest-grade gold mine and Omega flanked by Agnico Eagle’s Upper Beaver deposit and the Kerr-Addison Mine, we believe the future economic potential of these assets is significant, and we want our shareholders to own as much of it as possible.”
