Sego Has Mobilized Drill and Team to Miner Mountain

Vancouver, British Columbia--(Newsfile Corp. - November 12, 2025) - Sego Resources Inc. (TSXV: SGZ) ("Sego" or "the Company") is pleased to announce that the diamond drill and field team have arrived at the Miner Mountain Alkalic Copper-Gold and Gold project. The team is now preparing drill pads in advance of the driller's arrival. A total of ~1000 m drilling is anticipated.

Alkalic Porphyry Copper-Gold mineralization that occurs at Miner Mountain encompasses a disseminated, near-surface bulk mineable disseminated gold mineralization in the South Gold Zone and deeper porphyry structural controlled copper-gold mineralization in the Cuba Zone.

Drill intersections of the South Gold Zone range to maximum 1.08 gpt gold over 88.0 m and occur within a mineralized oval zone measuring 285 m long, a maximum 145 m wide and vertical depth of ~70 m (Figure 1).

Program – South Gold Zone

• The South Gold Zone status is currently viewed as a "Target Reviewed" 90,000 to 150,000 ounces of gold in near surface mineralization, based on the 2024 SRK Canada Consulting review (Sego News Release September 24, 2024).

• Four holes that total ~470 metres are planned to confirm the continuity of gold mineralization in the 80 m gap between sections on the attached map of the South Gold Zone, collect specific gravity measurements of drill core and elevate the Gold Zone into an NI 43-101 resource "possible" category (Figure 1, collars A to D).

• A non-cyanide based leaching process of South Gold Zone samples will be tested to confirm a preliminary bench scale cyanide test which returned gold recoveries of 95% completed in 2021 (News Release, August 11, 2021) and to also improve the economic and environmental benefits of this new process.

Program – Cuba Zone

• Deep drill holes are planned in the Cuba Zone located 1,700 m northeast of the South Gold Zone.

• A diamond drill hole will explore ~500 m depths below a +1% copper porphyry intersection shown in a long section in Figure 2.

• Drill hole 37 carried 4.4 m of 1.2% copper and 0.24 gpt gold within a wider 11 m interval containing 0.6% copper, 0.12 gpt gold mineralization at the final depth of 233 m (News Release February 28, 2019).

• In addition, platinum group metals will be analyzed in zones of new mineralization which are indicated in 0.13 gpt palladium over 2 m in drill hole 37 (News Release October 24, 2023).
