Nord Confirms Castle Surface Gold Trend to 560 Metres Long Within the High-Grade Silver Mineralization Zones
Nord Precious Metals Mining Inc. (NTH) has reported results from a prospecting and stripping program conducted in July 2026 at its Castle East property, identifying a new surface gold corridor that extends the known trend to approximately 560 metres. The work, carried out by Laurentia Exploration between July 13 and 21, 2026, validated the presence of gold mineralization above the company’s existing high-grade silver-cobalt system.
Key surface sampling highlighted a prospecting sample, L339955, which returned 2.80 g/t gold at UTM 17N 520302E 5278971N. This finding extends the strike length of known surface gold occurrences along a northeast-trending corridor. Near the overlap of the extended 2023 stripped exposure, channel sampling returned 2.09 g/t gold over 1.6 metres. This interval included higher-grade sub-intervals of 2.51 g/t gold over 0.7 metres and 1.77 g/t gold over 0.9 metres. Additionally, grab samples from the newly extended and previously exposed 2023 stripped exposure returned 2.47 g/t gold and 1.22 g/t gold. The company noted that grab samples are selective and not representative of average grades.
A total of 34 samples were collected, comprising seven prospecting, 17 channel, and 10 grab samples, along with one blank and one standard. All samples were analyzed for silver. The program extended the 2023 stripped exposure to approximately 10 x 5 metres, with four channels totaling 17 samples cut on 0.40 to 0.70 metre intervals across newly exposed veins. The 2015 stripped exposure was enlarged to approximately 10 x 10 metres for grab sampling. Structural mapping identified three principal vein sets, with the dominant subvertical set striking north to north-northwest being the most strongly mineralized.
The surface findings build upon previous drilling context from hole CS-23-123, which intersected gold below surface showings. This included 3.05 g/t gold within an approximately 9 metre downhole zone of anomalous gold in strongly chloritized and fractured rock, which included a sub-interval of 1.41 g/t gold over 3.83 metres. Significant silver values were also identified in the diabase below, including 5,441.4 g/t silver over 0.37 metres at depth 446.55-446.92 metres and 3,730 g/t silver over 0.75 metres at depth 461.25-462 metres.
Assays were performed by Swastika Laboratories Ltd. in Swastika, Ontario. Gold was analyzed using fire assay with an AA finish, while silver was analyzed via aqua regia digestion. Quality assurance and control included one certified blank and one certified standard inserted among the 34 samples. Data recording was confirmed using cellular location in the QField application and a Garmin GPSMAP 65s.
Frank J. Basa, P.Eng., Chief Executive Officer of Nord, commented on the findings: "The gold corridor gives Castle East a second dimension at surface, above and around the high-grade silver system we continue to target at depth. Because crews and equipment were already mobilized, this work was completed at minimal incremental cost. We are not assuming the gold and the silver-cobalt systems are connected; each target will be advanced on its own merits within one district-scale property."
The company plans an expanded fall program to further define the geological model. Pending assay results from recent deep silver drilling, which previously intersected high-grade silver intervals, are expected to be reported upon receipt. All reported widths are downhole or channel lengths; true widths have not been determined. The technical information in this release was reviewed and approved by Frank J. Basa, P.Eng., Director of the Company, who serves as the Qualified Person.
