Upper Antino represents the most advanced and intensively drilled target within the Antino Gold District and continues to serve as a key anchor for Founders Metals’ exploration efforts. The prospect has demonstrated consistent growth through step-out drilling to the east and along strike with a current mineralized footprint spanning ~2,600 m along strike, ~750 m wide, and ~600 m vertical depth.

Key drilling intercepts include:

• 15.5 m of 30.72 g/t Au
• 46.0 m of 5.31 g/t Au
• 19.0 m of 14.23 g/t Au

Founders has identified three major opportunities for growth: connecting the dots between Froyo and Donut, doubling the depth with deeper drilling, and extending north and south along strike.

Buese represents a high-priority, bulk-tonnage exploration target situated approximately 6 km southeast of Upper Antino. Gold mineralization occurs over broad intervals of moderate grade within and on the margins of intrusion hosted orogenic gold mineralization. 

Drilling highlights at Buese to date include:

• 78.0 m of 2.35 g/t Au, including 20.0 m of 7.65 g/t Au
• 21.6 m of 2.38 a/t Au
• 112.0 m of 0.55 g/t Au

The Company’s current drilling plans at Buese is to better delineate high-grade zones and expand potential footprint.

Lower Antino continues to demonstrate scale and consistent grade, reinforcing its emergence as a significant gold target and potential companion to Upper Antico’s share hosted vein mineralization. Gold mineralization occurs over multiple 15-90+ metre wide, sub-parallel gold zones along the 1,900 m strike with opportunity to grow. Recent drilling has intersected high-grade with up to 28.44 g/t Au in a single drill intercept.

Drilling highlights to date at Lower Antino include:

• 90.0 m of 1.02 g/t Au
• 81.9 m of 1.00 g/t Au
• 50.0 m of 1.02 g/t Au

Lower Antino remains a high-priority target for continued investment and advancement.

Da Vinci was discovered by Founders in December 2024 and is 10 km from Upper Antino along the same shear structure with seven of the first eight holes all having wide intersections of gold mineralization. Da Vinci occurs in mixed sequence of metasedimentary rocks with growing scale. Drilling has confirmed from surface gold mineralization over 150 m of strike and ~250 m true depth.

Drilling highlights to date at Da Vinci include:

• 36.0 m of 2.21g/t Au
• 67.0 m of 1.26 g/t Au
• 28.5 m of 1.30 g/t Au
• 25.0 m of 1.01 g/t Au

Follow-up drilling will further test mineralization along-strike and to the NE and SW for additional repeating structures and gold zones.

Maria Geralda was discovered in June 2025 and is an emerging, drill-confirmed gold target situated approximately ~8 km southeast of Upper Antino. The drilling follows up on a systematic surface exploration program, including prospecting, mapping and augering programs that identified a 500 m by 400 m gold anomaly at surface where 54% of samples returned assays above 0.1 g/t Au. The third drill hole at Maria Geralda intersected 22.5 m of 11.88 g/t Au, the highest-grade interval outside of Upper Antino to date!

Founders plans to follow-up on the initial drill program in 2025 and believe there is significant expansion potential along strike and to depth.

Van Gogh is located ~12 km southeast of Upper Antino and was initially discovered in January 2025 with a high-grade channel sample intersecting 17.8 m of 5.68 g/t Au. Follow-up drilling confirmed the high-grade gold mineralization with 28.5 m of 7.12 g/t Au and 72.0 m of 2.29 g/t Au within the first six drill holes on the property.

Gold mineralization at Van Gogh occurs within a ~30 m wide mylonite zone with up to 5 m intervals of strongly silicified country rock and quartz. The gold-rich intervals locally contain up to 15% sulphide (pyrite) and the highest-grade intervals are often associated with brecciation.

Founders intends to complete additional surface work first before continuing to drill. Given the scale and very high-grade nature of the initial Van Gogh results, the Company intends to return to Van Gogh to complete up to 3,500 m of drilling in 2025.

Parbo is ~8 km east of Upper Antino and hosts an expansive 1,200 m x 700 m historical auger anomaly, where samples have returned grades up to 51.42 g/t Au.

Founders plans to begin a surficial exploration program by mid-July that includes up to 1,500 m of trenching, expansion of the historical auger grid, and detailed geological mapping. Following evaluation of results from this surficial program, the Company is planning a preliminary drill program of up to 2,000 m in 2025.

Lawa is ~ 14 km southeast of Upper Antino target represents a major structural corridor with significant discovery potential, comprising over 8,000 m of mapped shearing and extensive artisanal workings. Gold mineralization occurs within sheeted tension vein arrays, presenting as both disseminated pyrite and visible free gold in sheared quartz veins that run sub-parallel to regional structures.

Recent exploration has yielded promising results, including channel sampling at Lawa North returning 27.0 m of 1.99 g/t Au. Initial drilling at Lawa South has consistently intercepted broad intervals of gold mineralization in all holes, including visible gold.

The Company plans comprehensive follow-up work including additional surficial exploration and an expanded drilling program. This systematic approach will help define the system's full potential while identifying the most prospective areas for higher-grade mineralization.
