Vancouver, British Columbia - Newsfile Corp. - April 2, 2026 - Founders Metals Inc. (TSXV: FDR) (OTCQX: FDMIF) (FSE: 9DL0) ("Founders" or the "Company") announces a new high-grade gold discovery at its Antino Gold Project ("Antino" or "Project") in southeastern Suriname. The Company reports high-grade gold mineralization from surface, returning 17.22 grams per tonne (g/t) gold (Au) over 3.6 metres (m) within a broader 24.6 m interval grading 2.81 g/t Au, in the first-ever drillhole in the Antino North area (Figure 1). HighlightsFirst ever Antino North drilling delivers exceptional results from surface in the first drillhole (AN001)

• 24.6 m of 2.81 g/t Au including 3.60 m of 17.22 g/t Au from 1.5 m down hole
• 13.5 m of 0.44 g/t Au from 54.6 m

• First drillhole testing one of twelve gold-bearing structures identified to date at Antino North
• Surface work continues:
  • Over 4,500 auger samples to date in 2026
  • Total combined strike length of mapped shear zones on surface is 5.3 km
  • Second Antino North drill now turning on previously undrilled kilometre-scale gold auger anomaly (Figure 2)

Colin Padget, President & CEO, commented, "The Antino North area covers nearly 10,000 hectares of highly prospective geology that has never seen a drillhole - so we are thrilled to see such high-grade results from our first diamond hole into the area. Our team on the ground has so far mapped twelve parallel shear zones across and along strike of the intercepted structure, and we plan to test many of them over the current ~3,500 metre phase-one drill program. This Antino North discovery reinforces our belief that the larger Antino Project is host to a major district-scale gold system, and there remains significant exploration upside and opportunity for further discoveries with this year's exploration program." Antino North Drilling The new discovery is hosted within a series of approximately 5- to 25-metre-wide shear zones, with geological characteristics consistent with high-grade gold mineralization documented elsewhere on the Antino Gold Project, including at Upper Antino. The reported drillhole tested the first of twelve northwest-trending parallel shears recently mapped over multiple kilometres across the Antino North area, highlighting the significant scale of the mineralizing system. The mapped shear zones are spatially coincident with a large regional-scale fold - a structural setting commonly associated with orogenic gold deposits across the Guiana Shield. Mineralization is similar in character to the shear- and vein-hosted gold mineralization at Upper Antino, comprising sheared subvertical quartz veins with late brittle deformation overprinting and a sericite-ankerite-tourmaline alteration assemblage. The Antino North concession has no record of historical diamond drilling. This discovery represents the first drill-tested gold zone within the recently acquired exploration concession, located approximately 20 kilometres southwest of the Upper Antino area - confirming the potential for new mineralized centres across the district-scale Antino land package. Table 1: Drill Hole Assay Results

Drillhole	From (m)	To (m)	Interval (m)	Au (g/t)
AN001	1.50	26.10	24.60	2.81
incl	1.50	5.10	3.60	17.22
and	54.60	68.10	13.50	0.44

*Intervals are down-hole depths. True widths of mineralization are unknown at this time based on currently available results and observations. All are diamond drill holes. Interval average grades are calculated with un-capped gold assays, as insufficient drilling has been completed to determine capping levels for higher-grade gold intercepts. 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. Table 2: Drill Hole Locations
