James Nelson, President of Adelayde, stated, "Critical metals, including tungsten and antimony, as well as rare earth minerals, have once again been thrust into the global spotlight as the dispute between USA and China for these have escalated according to a Reuters report⁽¹⁾. The combination of China's tightening control over tungsten production and the growing demand for this critical material has made tungsten even more valuable on the global market. The junior markets continue to be very buoyant for tungsten evidenced by the strong movement of companies such as American Tungsten Corp., TUNG, whose shares have risen from $0.03 cents in October 2024 to a high of $4.74 on October 10, 2025, showing the strong investor demand for tungsten related companies." Mr. Nelson went on to say, "In addition, with gold prices near all-time highs, the company is excited to launch a maiden drill program on the Esmeralda County Gold Project in Nevada in 2025. The company will be very active for the remainer of 2025 and beyond, and management is very optimistic about the short and long-term growth prospects."

The Company has agreed to acquire the Sisson NW Tungsten Project by issuing a total of 6,000,000 common shares (subject to a four-month hold period) at a deemed price of $0.11 and by making cash payment in the amount of $5,000 as set out below:
