Adelphi Metals Inc. (CSE: ADP) has released assay results from 215 rock samples collected in July 2026 at its Brady Sudbury Project in Ontario, reporting seven samples exceeding 30 g/t gold and geochemical signatures consistent with an iron oxide copper-gold exploration model. The results include grab samples returning up to 53.9 g/t gold at the Golden Pine zone and up to 49.2 g/t at the Galena Vein in the Marble Mountain corridor. Investors may be watching to see how planned geophysical surveys and follow-up sampling define drill targets across the property.

Key Points

  • Adelphi Metals Inc. (CSE: ADP) is a Canadian junior explorer advancing the Brady Sudbury Project in Ontario
  • Seven bedrock grab samples exceeded 30 g/t gold, with the highest returning 53.9 g/t at Golden Pine
  • Six samples returned 6.0% to 8.2% Na₂O, suggesting sodic alteration; petrographic confirmation is pending
  • Ground gravity and airborne VTEM surveys are planned to define targets along a 4 km geophysical anomaly never previously drill tested

High-Grade Gold Surfaces at Golden Pine and Marble Mountain Galena Vein

The July 2026 sampling program at Brady returned gold values ranging from below detection to 53.9 g/t across 215 rock samples. Five bedrock grab samples at Golden Pine and the Marble Mountain Galena Vein returned final assays of 53.9, 49.7, 37.0, 49.2 and 46.7 g/t gold respectively. Two additional Galena Vein samples exceeded 30 g/t gold by fire assay, with metallic screen results still pending. The release cautions that grab samples are selective by nature and may not represent average grades or true zone widths. The Galena Vein also returned four samples with 222 to 747 g/t silver and 16.1% to 42.8% lead.

Sodic Alteration and Associated Metals Reinforce IOCG Exploration Model

Six samples returned sodium oxide (Na₂O) concentrations of 6.0% to 8.2% alongside less than 1% K₂O, a composition the company describes as albitite-like and consistent with sodic alteration documented in iron-rich mineralised systems in the Sudbury area. The announcement notes petrographic confirmation has not yet been completed. Gold-bearing samples also show iron enrichment and locally elevated cobalt up to 587 ppm, tellurium up to 124 ppm, bismuth up to 931 ppm, and rare earth elements. The company states these geochemical hallmarks support the iron oxide copper-gold model it is testing at Brady.

North River Copper-Gold Results and Structural Interpretation

At the North River claims, which include the Wanapitei Fault, 11 of 20 samples returned 0.1% copper or better. Bedrock samples returned up to 0.72 g/t gold with 0.14% copper, while two mineralised boulders — whose bedrock source has not yet been traced — returned 1.71 g/t gold and 1.28 g/t gold with 1.76% copper, the highest copper value recorded on the property. The company's geologists interpret this copper-gold vein material as the upper portion of a mineralised system, with a planned ground gravity survey designed to test for a dense, iron-rich body at depth.

Geophysical Surveys and Drill Target Definition Outlined as Next Steps

Adelphi has outlined a two-survey program to advance Brady: a ground gravity survey at North River and an airborne electromagnetic VTEM survey over the Marble Mountain corridor to map sulphide zones. These results will be integrated with structural mapping, channel sampling and historical induced polarization data to define targets for a maiden drill program, including along a 4 km geophysical anomaly in the Marble Mountain corridor that has never been drill tested. The technical content of the announcement was reviewed and approved by François Gagnon, P.Geo., an independent qualified person under National Instrument 43-101.
