Adelphi Metals Reports High-Grade Gold and IOCG Style Mineralization at Brady Sudbury Project

Vancouver, BC – October 22, 2026 – Leads & Copy – Adelphi Metals Inc. (CSE: ADP) has reported results from 215 rock samples collected in July 2026 at its Brady Sudbury Project in Ontario. The program identified high-grade surface gold at Golden Pine and Marble Mountain, sodium-enriched rocks, and a metal signature consistent with the company’s iron-rich, fault-controlled exploration model. The North River claims, which include the Wanapitei fault, contained numerous samples of copper and gold in an IOCG type setting.

Gold values ranged from below detection up to 53.9 g/t, with five bedrock grab samples returning final values of 53.9, 49.7, and 37.0 g/t gold at Golden Pine, and 49.2 and 46.7 g/t at the Galena Vein in the Marble Mountain corridor. Two additional Galena Vein bedrock samples exceeded 30 g/t gold by fire assay; metallic screen results are pending.

Six samples returned 6.0% to 8.2% Na₂O and less than 1% K₂O, consistent with an albitite-like composition, though petrographic confirmation has not been completed. In the Sudbury area, this type of sodium-rich alteration is documented as a main host of mineralization in iron-rich systems.

Gold-bearing samples show iron enrichment and locally elevated cobalt, tellurium, bismuth, and rare earth elements. Reported values include up to 587 ppm cobalt, 124 ppm tellurium, and 931 ppm bismuth. At the Galena Vein, four samples returned 222 to 747 g/t silver and 16.1% to 42.8% lead, and one returned 1.58% zinc.

The company interprets the 2026 results as following the structure of the Wanapitei Fault system. High-grade gold at Golden Pine and Marble Mountain sits on faults branching from the Wanapitei Fault, while copper is concentrated on the main fault at North River, which accounted for 11 of the 20 samples on the property returning 0.1% copper or better. The same arrangement is seen across Wanapitei Lake, where the company interprets the fault as continuing as the McLaren Lake Fault; the Alwyn copper-gold prospect sits on the main fault, with the past-producing Scadding gold mine on a branch beside it.

Samples returning 1 g/t gold or better carry more than twice the iron of low-gold samples, and in the Marble Mountain corridor that iron is held mainly in sulphide minerals. The gold occurs with silver, and locally with cobalt, rare earths, and uranium, alongside sodium-rich alteration. These are hallmarks of iron oxide copper-gold (IOCG) and related systems, the model the company is testing at Brady.

At North River, bedrock samples returned up to 0.72 g/t gold with 0.14% copper, and two mineralized boulders, whose bedrock source is yet to be traced, returned 1.71 g/t gold and 1.28 g/t gold with 1.76% copper, the highest copper value on the property. The company’s geologists interpret these copper-gold veins as the upper part of a mineralized system, and the planned ground gravity survey will test for a dense, iron-rich body below.

“These are the first assays from our first season at Brady and they are consistent with the model we set out to test,” said Michael England, CEO of Adelphi Metals. “High-grade gold at several locations, sodium enrichment in the chemistry and a large undrilled geophysical anomaly give us clear targets for the next phase of work.”

Next steps include two geophysical surveys: a ground gravity survey at North River to test for a dense, iron-rich body at depth, and an airborne electromagnetic (VTEM) survey over the Marble Mountain corridor to map sulphide zones that carry gold. The results will be combined with follow-up structural mapping, channel sampling, and historical induced polarization data to define drill targets, including along the 4 km geophysical anomaly in the Marble Mountain corridor, which has never been drill tested, for a maiden drill program at Brady.

Rock samples were collected by the company's field crews between July 8 and July 26, 2026. Samples were submitted to Activation Laboratories Ltd. (Actlabs). Certified reference materials and blanks were inserted every 20 samples for quality control.
