Regency Silver Corp. (TSX-V: RSMX) (OTCQB: RSMXF) (FSE: ZJ90) reports complete results from the 2025/2026 drill campaign at its wholly owned Dios Padre Project, located near Yecora, Sonora, Mexico. The 2026 portion of the campaign comprised 9 drill holes totalling 6,234 metres. Hole REG-26-35 returned 5.06 g/t gold, 41.85 g/t silver, and 1.10% copper over 36.35 metres within a broader 96.00-metre zone averaging 2.08 g/t gold, confirming additional high-grade gold-copper-silver at depth. The 2025 results were reported in a news release dated March 2, 2026.

KEY HIGHLIGHTS

• REG-26-35 (High-Grade Gold): 5.06 g/t Au, 41.85 g/t Ag and 1.10% Cu over 36.35m, within a 96.00m zone of 2.08 g/t Au – located ~25m along strike to the southeast from discovery hole REG-22-01.
• REG-26-29 (High-Grade Silver): 266.04 g/t Ag and 0.56% Cu over 7.55m, within a 21.2m zone of 107.73 g/t Ag and 0.27% Cu – located ~250m below the historic Dios Padre Silver mine and ~230m up dip from REG-26-35.
• System Scale Confirmed: The breccia body hosting silver-copper-gold mineralization at the historic Dios Padre Silver mine has now been intersected at both ~125m and ~250m below the Dios Padre silver mine and appears to be continuous to the deepest drilling point. The down-plunge extent of the breccia host to mineralization now extends to approximately 775 metres.
• Vertical Zoning pattern: Results demonstrate a silver-copper-rich profile at shallower depths transitioning to gold-copper mineralization at depth – This is likely an effect of thermal gradation with Ag rich zones representing a cooler part of the system and the Au rich zones representing a hotter part of the system. This is a pattern observed in robust magmatic-hydrothermal porphyry-epithermal systems.
• High-Grade Gold sub-intervals in REG-26-35: 10.82 g/t Au over 3.20m (544.00-547.20m) and 14.48 g/t Au over 2.80m (554.50-557.30m).
• • REG-26-33 (Broad Gold Zone): 0.42 g/t Au over 150.50m (384.50-535.00m), including 0.76 g/t Au over 28.70m.

MANAGEMENT COMMENTARY

“The 2026 drill program has been highly successful. REG-26-35 is the most significant hole drilled to date due to its high content of gold, silver and copper. We can now confirm that the breccia hosting mineralization at the silver mine is likely continuous to the deeper Au-Cu rich breccia. The dimensions of the mineralized breccia at depth are now ~230m by ~150m by ~50m and the high-grade portion within that zone is now ~150 by ~75m by ~50m. Hole REG-25-26 extends the breccia mineralization ~125m below the Dios Padre mine with Hole 26-29 demonstrating continuity to ~250m below the mine. The mineralized zone remains open in all directions.”

WORK PROGRAM

In preparation for the next phase of the drill program the Company is currently assessing the results of the 2025/26 drill program and continuing with its mapping and sampling of both the Dios Padre property and the nearby La India property. The drill has been removed from the property and drilling is planned to resume upon completion of such assessment.

GEOLOGICAL CONTEXT AND SIGNIFICANCE

The Dios Padre Project is a magmatic-hydrothermal breccia system located near Yecora, Sonora, Mexico. Regency Silver Corp. has identified a large mineralized system that appears to widen at depth, with the primary breccia body now confirmed to extend over a down-plunge distance of approximately 775 metres. The system exhibits a vertical zonation from silver-copper-dominant mineralization at shallower levels to gold-copper-dominant mineralization at depth.

The 2025/2026 drill campaign (holes REG-25-23 through REG-26-35, totalling 9,375 metres across 14 holes) represents step-out and infill drilling southeast and up-dip of previous high-grade intercepts. Hole REG-26-35 is located approximately 25 metres along strike to the southeast of discovery hole REG-22-01 (35.8m of 6.84 g/t Au, 0.88% Cu, 21.82 g/t Ag) and approximately 40 metres from REG-23-21 (38m of 7.36 g/t Au). These results confirm lateral and vertical continuity of the high-grade gold-copper-silver zone.

QUALITY ASSURANCE / QUALITY CONTROL

Drill core was received at site, individually sampled, logged for geological attributes, sawn in half, labelled, and sealed for assay submission. The retained half-core is stored at a secure facility at the historic Dios Padre mill site. Quality control samples – including blanks, preparation duplicates, and certified reference materials – were inserted at regular intervals within every sample shipment to monitor laboratory performance. All shipments were conducted under a formal chain-of-custody procedure.

Samples were submitted to ALS Global’s analytical facility in Hermosillo, Mexico (ISO 9001 and ISO/IEC 17025 certified). Analytical methods:

• Gold (Au): Method Au-AA23 – 30g fire assay fusion with AAS finish (0.005-10 ppm). Assays >10 ppm upgraded to Au-GRA21 (30g fire assay gravimetric finish).
