Adelphi Metals Reports High-Grade Gold and Metal Findings at Brady Sudbury Project

Adelphi Metals Inc. has announced the results of a recent exploration program at its Brady Sudbury Project in Ontario, Canada. The company collected 215 rock samples in July 2026, which have revealed high-grade gold and other metals, supporting the company’s exploration model.

The samples collected at the Golden Pine and Marble Mountain areas showed significant gold values, with five bedrock grab samples returning final values of 53.9, 49.7, and 37.0 grams per tonne (g/t) gold. Additionally, two samples from the Galena Vein in the Marble Mountain corridor exceeded 30 g/t gold. The highest gold value recorded was 53.9 g/t, while other notable values included 49.2 and 46.7 g/t gold.

The exploration also identified sodium-enriched rocks, with six samples returning sodium oxide (Na₂O) values ranging from 6.0% to 8.2%. This sodium enrichment is consistent with the albitite-like composition documented in iron-rich systems in the Sudbury area, as described in previous studies (3, 4).

Associated with the gold, the samples also showed iron enrichment and elevated levels of cobalt, tellurium, and bismuth. The highest cobalt value was 587 parts per million (ppm), while tellurium and bismuth values reached 124 ppm and 931 ppm, respectively. At the Galena Vein, four samples returned silver values ranging from 222 to 747 g/t, and lead values between 16.1% and 42.8%. One sample from the same area contained 1.58% zinc.

The exploration results align with Adelphi Metals’ interpretation of the geological structure of the Brady Sudbury Project. High-grade gold is found on faults branching off the Wanapitei Fault, while copper is concentrated on the main fault at North River. The company’s geologists have noted that samples returning 1 gram per tonne (g/t) gold or better carry more than twice the iron content of low-gold samples. In the Marble Mountain corridor, the iron is primarily held in sulphide minerals, which are detectable through electromagnetic and induced polarization surveys.

At North River, bedrock samples returned up to 0.72 g/t gold with 0.14% copper. 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. These findings suggest the presence of copper-gold veins, which the company’s geologists interpret as the upper part of a mineralized system. The planned ground gravity survey will test for a dense, iron-rich body at depth.

The next steps for the project include conducting 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 the sulphide zones that carry the gold. The results will be combined with follow-up structural mapping, channel sampling, and historical induced polarization data to define drill targets.

The rock samples collected are grab and select samples, which are selective by nature and may not represent true grades or the average grade of any zone. The identification of sodic alteration is based on whole-rock geochemistry and visual observation and has not been confirmed by petrographic analysis.
