Silver Grail Announces Assay Results that Confirm Porphyry-Style Copper Mineralization at Eastern Magnetic Anomaly, Ram Property, Golden Triangle, BC

Silver Grail Resources Ltd. (“Silver Grail” or the “Company”) (“SVG” – TSX-V) (“SVGAF” – OTCID) reports assay results from its 2025 inaugural diamond drill program on the Ram Property, located approximately 7 kilometres (“km”) southwest of the Red Mountain gold-silver deposit in British Columbia’s Golden Triangle. The program comprised 1,978 metres (“m”) of NQ-diameter core drilling in seven drill holes from two drill setups located approximately 625 metres apart, testing two previously unexplained magnetic anomalies. The Ram Property is jointly owned with Silver Grail Resources Ltd. Assay results returned elevated gold, copper and molybdenum values across multiple zones, with individual assays that range from nil to 3.64 grams per tonne (“g/t”) gold (“Au”), nil to 3,294 parts per million (“ppm”) copper (“Cu”), and nil to 489 ppm molybdenum (“Mo”), confirming the presence of a broad mineralized system and supporting further follow-up work. 2025 Ram Project Drill Highlights Include: * Assay results confirm that the Eastern Magnetic Anomaly represents a porphyry-style copper-gold-molybdenum system * Long, continuous intervals of copper mineralization intersected at the Eastern Magnetic Anomaly within an altered magnetite-bearing multiphase intrusive complex, including: * 91.00 m grading 303 ppm Cu (RAM25-002, 6.00 – 97.00 m) * 152.00 m grading 292 ppm Cu (RAM25-002, 179.00 – 331.00 m) * 163.40 m grading 151 ppm Cu (RAM25-007 173.60 – 337.00 m) * Elevated molybdenum values, locally exceeding 100 ppm and up to 489 ppm, support the interpretation of a fertile porphyry environment * Drilling at the Western Magnetic Anomaly intersected narrow, near-surface, higher-grade Au ± Cu ± Mo vein mineralization, including 1.00 m grading 3.64 g/t Au in RAM25-004 (180.50–181.50 m). Results validate interpretations from the September 10, 2025, visual-results news release and confirm that both magnetic anomalies are associated with significant mineralization Dino Cremonese, P.Eng., CEO of Silver Grail, commented: “We are encouraged that assay results have now confirmed what we interpreted from visual logging and surface work earlier in the program. Drilling has demonstrated that the Eastern Magnetic Anomaly is directly related to a copper-molybdenum-gold porphyry system, characterized by broad zones of continuous copper mineralization. While grades are modest at this stage, the scale and consistency of mineralization confirm a legitimate porphyry copper exploration target at Ram. In addition, localized higher-grade vein intersections at the Western Anomaly highlight a potentially related broader mineralizing system.” Quality Control Silver Grail drilled NQ (47.6mm) sized core on the Ram 2025 program. All drill core was logged, photographed and cut in half with a diamond saw at Silver Grail’s core facility in Stewart, northwestern BC. Samples were typically 2-metres-long but in areas of interest sample sizes were reduced. Half core samples were transported directly from the core facility to MSALABS preparation laboratory in Terrace BC. Sample pulps were shipped by MSALABS from the preparation facility to the MSALABS geochemical laboratory in Langley BC. At the laboratory, the samples were dried, crushed and pulverized using standard rock preparation procedures. Each sample was crushed to 70% passing 2 mm, a riffle split 250 g was pulverized to better than 85% passing 75 microns (MSALABS Code PRP910). The pulps were then analyzed for Au using a 30 g fire assay (MSALABS Code FAS-111). An additional 48 elements were tested with a four-acid digestion, multi-element ICP-MS package (MSALABS code IMS-230). Quality control at the laboratory is maintained by submitting blanks, standards and re-assaying duplicate samples from each analytical batch. Silver Grail implemented an internal Quality Assurance/Quality Control program with the insertion of blanks and certified standards at a ratio of at least 1 per 25 samples.
