Nord Precious Metals Mining Inc. Identifies Gold Targets in Castle–Gowganda District on Trend with Côté Gold Mine

Cobalt, Ontario — July 13, 2026 — Leads & Copy — Nord Precious Metals Mining Inc. is advancing exploration targets for gold across its consolidated Castle–Gowganda district, situated on trend with the producing Côté Gold mine along the Ridout-Tyrrell corridor. This initiative will proceed in parallel with the Company’s ongoing silver-focused drilling and tailings recovery program.

The Abitibi greenstone belt, a major gold-producing region globally, hosts substantial deposits of gold, silver, copper, nickel, and cobalt. Significant gold reserves have been identified within the Destor-Porcupine and Cadillac–Larder Lake deformation zones. The Ridout-Tyrrell deformation zone is increasingly recognized for its precious metal deposits and occurrences, including IAMGOLD’s Côté Gold, McFarlane Lake Mining’s Juby Gold, and the Gowganda Silver Camp.

Nord is consolidating gold results from its Castle–Gowganda district to establish a ranked set of exploration targets. Initial surface discoveries, identified through boulder-train mapping, yielded assays of 1.32 g/t and 1.25 g/t gold, with associated copper values up to 1.03% as previously reported on December 8, 2014.

Following these surface findings, diamond drilling in 2018 revealed a significant near-surface hydrothermal system. This system featured gold-bearing quartz veins with a halo of disseminated nickel and copper mineralization within Archean volcanics, situated above the Nipissing diabase – the primary host rock for the Gowganda Silver Camp's production of 60 million ounces of silver.

Earlier stripping and channel sampling programs returned values of up to 3.77 g/t gold over 1.27 metres, as previously disclosed on April 2, 2015. Subsequent drill holes have intersected gold, including a shallow interval in hole CS-20-31 at 49.7 meters downhole, which returned 24.95 g/t gold over 0.3 meters and contained coarse visible gold. Additionally, at a depth of 451.0 meters downhole, another intercept yielded 3.82 g/t gold over 2.86 meters, including 6.11 g/t gold over 1.66 meters. These intercepts are located near the Robinson Zone but are interpreted as being distinct from the associated silver-cobalt vein mineralization, suggesting a separate Archean gold system within the district. Individual assays in this setting can be significantly affected by coarse gold, also known as the nugget effect. Unless otherwise specified, reported intervals represent downhole core lengths, and true widths are not yet determined.

Gold identified in stripping operations is located southwest of the Robinson Zone, with the 2014 stripping area approximately 400 metres away and the 2023 stripping area about 800 metres distant. Multiple gold intercepts have been drilled below these areas. Hole CS-19-19 intersected 4.3 g/t gold over 4.0 metres and 1.5 g/t gold over 12.5 metres within a broader 30-metre mineralized zone grading 0.70 g/t gold at a vertical depth of approximately 240 meters. This interval included one meter assaying 15.2 g/t gold.

While parts of the Ridout-Tyrrell deformation zone are covered by Proterozoic glacial sedimentary rocks, its extension through the Gowganda area within Archean greenstone rocks is supported by numerous gold-bearing structures west of Nord’s Gowganda holdings, as well as Nord's own surface and drill-hole gold results. The Nipissing intrusion cuts through this region, presenting a potential link between the Archean gold system and younger silver-cobalt vein systems both above and below the intrusion. Geological interpretations suggest several structural corridors where elevated gold, silver, and cobalt values in overlying Proterozoic rocks may indicate underlying gold-mineralizing systems in Archean rocks. Further work is underway to test these interpretations.

In addition to the ongoing exploration for silver mineralization at the Castle East deposit, strategically placed holes in the current drilling phase are designed to test gold values identified during 2014 and 2023 stripping programs, without compromising the primary silver-focused objectives at Castle East.

The Castle East silver deposit is situated atop a large Archean shear, which may have been instrumental in both the deposition of Archean gold mineralization and the potential remobilization of these metals into younger silver veins. This relationship was first outlined by the Company in March 2024 and is consistent with historical accounts from the Gowganda Camp describing silver bars containing recoverable gold.

Nord is compiling its surface and drill-hole gold results across the consolidated district into a unified structural framework. This compilation will aid in ranking targets for subsequent mapping, prospecting, and stripping during the current field season, with drill testing to be sequenced within the 30,000-meter program based on warranting results. The silver tailings recovery program remains the Company’s immediate priority, with the identified gold targets representing district-scale optionality being advanced concurrently.

“The Gowganda camp established its reputation in silver, but gold has consistently appeared in our exploration work for the past decade—in boulder trains, channel samples, and within the core between the veins,” stated Frank J. Basa, P.Eng., Chairman and Chief Executive Officer. “Côté has proven the potential of the Ridout-Tyrrell corridor at scale, and our consolidated land package is strategically located at the intersection of that corridor and the camp. Compiling and ranking our existing assets is a low-cost endeavor with potentially significant value. The tailings recovery program remains our top priority; these gold targets provide valuable upside potential.”

Nord Precious Metals Mining Inc. operates TTL Laboratories, the sole permitted high-grade milling facility in Ontario's historic Cobalt Camp. The Company has established an integrated operation that links high-grade silver discovery with strategic metals recovery. The flagship Castle property, spanning 63 square kilometers and augmented by 225 hectares of leases, includes three of the five most productive past-producing silver mines in the Gowganda Camp: Siscoe-O’Brien, Castle, and Millerett. This is complemented by the Castle East discovery, where drilling has defined a historical inferred resource of 7.56 million ounces of silver, averaging 8,582 g/t Ag (250.2 oz/ton) in 27,400 tonnes of material from two sections (1A and 1B) of the Castle East Robinson Zone, beginning at an approximate vertical depth of 400 meters. The Company also holds a strategic portfolio of critical minerals properties in Northern Quebec through its 35% ownership in Coniagas Battery Metals Inc. (TSXV: COS), and the St. Denis-Sangster lithium project, covering 32 square kilometers of prospective ground near Cochrane, Ontario.
