(MENAFN- Newsfile Corp) Vancouver, British Columbia--(Newsfile Corp. - November 20, 2025) - Founders Metals Inc. (TSXV: FDR) (OTCQX: FDMIF) (FSE: 9DL0) ("Founders" or the "Company") announces that it has signed the Definitive Agreement to acquire 100% ownership of the previously announced 36,000 hectare (ha) exploration concession west of the Company's Antino Gold Project ("Antino" or the "Project") in Southeastern Suriname (Figure 1). The acquisition expands the Project area to 56,000 ha and allows Founders to restart northwestward expansion drilling of Upper Antino, which was previously stopped at the concession boundary, but where historical auger gold anomalies support considerable potential growth (Figure 2).

Founders also announces drill core assay results from its ongoing 60,000 metre (m) drill program. The results extend Upper Antino gold mineralization to a total strike length of over 2,500 m, and include intervals of 17.0 m of 3.06 g/t Au in hole FR157 and a broader, near-surface interval of 60.0 m of 0.85 g/t Au from a depth of only 8.1 m in hole FR172 .

Colin Padget, Founders' President & CEO, commented: "This is a transformational period for Founders - over the past two weeks, we've closed a C$50 million strategic investment from Gold Fields, expanded the Antino land package to 56,000 hectares, and with today's results, demonstrated excellent along-strike, progressive growth of gold mineralization at Upper Antino.

With a strong cash position, a proven exploration team, and clear ability to operate efficiently in Suriname, Founders is well positioned to systematically explore our ever-growing land package of highly prospective geology with the proven potential to host multi-million-ounce gold deposits. Our four drills are currently turning at Da Vinci, Lower Antino, Parbo, and Upper Antino, with Van Gogh drilling planned to begin shortly. Results from Maria Geralda and Parbo are expected in the coming weeks, followed by results from other priority targets through Q4 and into early 2026."

Drilling Highlights:

250-metre Extension Along Parallel Gold Mineralization Continues Between Froyo and Donut

• 17.0 m of 3.06 g/t Au, including 4.0 m of 10.44 g/t Au from 195.0 m (FR157), confirming mineralization continues along strike to the southeast (Figure 2 & 3)
• 46.0 m of 1.03 g/t Au, within a broader 60.0 m interval of 0.85 g/t Au from 8.1 m (FR172), demonstrating near-surface mineralization with significant widths
• 14.0 m of 1.88 g/t Au from 225.0 m (FR154)

Main Froyo Zone Drilling Demonstrates Vertical Continuity Along Multiple Structures

• 7.0 m of 11.74 g/t Au from 197.0 m, 19.0 m of 1.18 g/t Au from 133.0 m, and 4.0 m of 5.10 g/t Au from 109.0 m (FR173)

Definitive Agreement

Founders has signed a Definitive Agreement and closed the transaction announced on October 31, 2025 to acquire 100% of the 36,000 ha Right of Exploration on the concession immediately west of Antino with an arm's length Surinamese private company. Total consideration for the acquisition comprises US$5.0 million (US$139/ha) in cash plus contingent milestone payments of: (1) US$1.0 million upon publishing a mineral resource estimate of 1 million or more ounces of gold, (2) a one-time payment of US$2.50 per recoverable ounce defined in a completed Feasibility Study, and (3) US$2.50 per ounce produced beyond the Feasibility Study estimate.

* Intervals are down-hole depths. True widths of mineralization are estimated to be approximately 85% of the down-hole interval based on currently available results and observations. All are diamond drill holes . Average grades are calculated with un-capped gold assays, as insufficient drilling has been completed to determine capping levels for higher grade gold intercepts. Average widths are calculated using a 0.10 g/t gold cut-off grade with <5.0 m of internal dilution of zero grade, and a minimum composite length of 2.0 m. Nothing included in table <1 gram * metre.
