.Regency Silver’s 2025 Drill Program Targets Sulphide‑Bearing Breccia Continuation at the Dios Padre Project, Sonora, Mexico

12/08/2025 – 04:00 AM

Vancouver, British Columbia – Regency Silver Corp. (TSXV: RSMX) (OTCQB: RSMXD) announced that follow‑up drill hole REG‑25‑25 intersected 23.7 m of sulphide‑specularite breccia (Figure 1). The breccia is analogous to that hosting high‑grade Au‑Cu‑Ag mineralization in historic holes REG‑22‑01, REG‑23‑21 and REG‑23‑14. The intercept lies approximately 35 m up‑dip and along strike to the southeast of hole REG‑23‑21, which yielded 38 m of 7.36 g/t Au. Hole REG‑22‑01 returned 35.8 m of 6.84 g/t Au, 0.88 % Cu and 21.82 g/t Ag, while REG‑23‑14 intersected 29.4 m of 6.32 g/t Au.

The 2025 follow‑up program began on 10 October 2025. To date, four holes totalling 2,476 m have been completed, including an extension of a vertical hole drilled in 2012. Hole locations and trajectories are illustrated on the plan view (Figure 2) and the 3D long‑section (Figure 3). The next hole, designated REG‑25‑05, will test the continuity of the breccia at shallower depths up‑dip toward the historic Dios Padre silver mine.

Preliminary visual inspection of REG‑25‑25 shows robust alteration, abundant sulphide mineralization and mineral species consistent with the historic high‑grade intervals. Although assay results are still pending, the geological signature strongly suggests comparable ore‑grade potential. For reference, detailed assay data for the historic intercepts can be found in company releases dated 23 February 2023 and 2 November 2023.

A key development in REG‑25‑25 is the discovery of a quartz‑feldspar porphyry (QFP) that brackets the mineralized breccia on both sides. QFP bodies are recognized as the primary drivers of brecciation and fluid flow in the Dios Padre system, creating pathways for sulfide deposition. The newly identified QFP appears to extend toward the bottom of the mineralized zone encountered in REG‑23‑21, offering a promising vector for additional Au‑Cu‑Ag zones.

Summary of additional holes drilled

• DP‑01‑2012‑EXT – Extension below 300 m of a historic hole that stopped short of the projected breccia. Broad zones of disseminated and vein‑hosted sulphide were intersected shortly after 300 m, confirming extension of the mineralized system to the northwest. No high‑sulphide breccia encountered; results pending.
• REG‑25‑23 – Targeted a deeper southeast extension of the breccia. Intersected 120 m (≈550‑670 m depth) of disseminated and locally vein‑hosted sulphides consistent with the projected zone, but no high‑sulphide breccia; results pending.
• REG‑25‑24 – Targeted a shallower southeast extension. Intersected 114 m (≈400‑514 m) of new disseminated sulphide mineralization, which abruptly terminates at a fault near 515 m depth; no significant mineralization beyond the fault; results pending.

Table 1: Drill‑hole coordinates and orientation

* The hole orientations were adjusted in this program to intersect the mineralized breccia at true width now that its geometry is better constrained. Topographic constraints required higher collar elevations, resulting in longer drill lengths. True‑thickness intersected is estimated at 70‑100 %.

Quality Assurance / Quality Control

Core samples were logged, split, labelled and bagged for assay. Quality‑control samples—including blanks, duplicates and standards—were inserted at regular intervals. All shipments were performed under chain‑of‑custody procedures.

Samples were sent to ALS Global’s laboratory in Hermosillo, Mexico. Gold assays were performed by fire‑assay with atomic‑absorption finish (Au‑AA23) and gravimetric finish (Au‑GRA21) for values above 10 ppm. Silver and base‑metal assays were conducted by multi‑element ICP‑AES (ME‑ICP61m) with appropriate digestion protocols. ALS Global holds ISO 9001 and ISO/IEC 17025 certifications; all QC results met acceptance criteria.
