MASON RESOURCES HIGHLIGHTS PERFORMANCE AND VALUE OF KEY PUBLIC MARKET INVESTMENTS

Mason Resources Inc.'s core equity investments in Nouveau Monde Graphite Inc., Black Swan Graphene Inc., Northx Nickel Corp. and Astra Exploration Inc. are delivering robust returns across public markets.

Investment performance highlights:

• Nouveau Monde Graphite: The U.S. Commerce Department recently indicated that it would impose preliminary anti-dumping duties of 93.5 per cent on anode-grade graphite imported from China after concluding that the materials, which are a key component for electric vehicle batteries, are being sold in the United States at less than fair market value. The news was received very positively, with North American-listed graphite companies and Nouveau Monde's share price enjoying strong growth in July. Mason is a large shareholder of Nouveau Monde.
• Black Swan Graphene: Following the $6-million financing in February, 2025, Black Swan recently announced the launch of graphene-enhanced masterbatches and recent commercial progress (see press release dated July 22, 2025); share momentum has reacted positively. Mason owns approximately 30 per cent of Black Swan.
• Northx Nickel: Northx was able to conclude the sale of its Sudbury properties, which greatly derisked the company (see press release on Jul 21, 2025, following which the share price has been positively impacted. Mason is a large shareholder of Northx Nickel.
• Astra Exploration: In recent weeks, Astra Exploration announced drilling results at its silver project in Argentina (see press releases dated June 25, 2025, and June 10, 2025). The company has been performing well since Mason became a shareholder of Astra Exploration.

"Our portfolio's success reflects the careful selection of high-potential, innovative companies," stated Fahad Al-Tamimi, chairman of Mason. "Each investment is executing on its strategy, whether in critical minerals, advanced materials or high-impact exploration, and the market is responding. We look forward to continuing to build value for our shareholders."
