Northern Shield Resources Inc. (TSX-V: NRN) is pleased to announce the results of the summer’s drilling at the Conquest Zone and ongoing field work on the Creston Copper Target, both on the Company’s 100%-owned Root & Cellar Property, on the Burin Peninsula, southeastern Newfoundland. The Property is being explored for epithermal gold mineralization, with 5 gold zones over a 6-kilometre strike-length, and porphyry copper at the Creston Cu-Mo-Au-Te target. Tellurium, a critical metal, is associated with 4 of the gold showings and the copper mineralization.

Conquest Drilling

The assays confirm gold and silver telluride minerals (Figure 1a) in the southern Conquest Zone with the most significant results in drillhole 25RC-34: 4.35 m @ 3.4 g/t Au, 5.7 g/t Te (130.60-134.95 m), including concentrations of 4.4 g/t Au and 8.6 g/t Te over 0.5 metres.  The mineralization is in pyritic breccias and distinct, crustiform-colloform banded quartz veins (Figure 1b and 1c), indicative of the boiling zone (the point of gold-silver precipitation in a low-sulfidation epithermal deposit) and the widest intersection of gold-mineralized epithermal quartz veins on the Property to date. Copper concentrations in this section grade up to 0.29% Cu over 0.6 metres. Drillhole 25RC-33 intersected 24.9 m @ 0.57 g/t Au (24.6-49.5 m).

Multiple short intersections of anomalous gold, silver +/- tellurium +/- copper were also intersected in drillholes 25RC-23, 24, 25 and 26. Drillhole 25RC-24 veered off course and did not intersect the intended target.

A new analytical package, used for this drilling program, detects Te at lower levels. In the past, the detection limit for Te was 10 ppm Te, suitable for high-grade samples, but not providing the resolution required for using Te as a vector / pathfinder element.  The results indicate increasing Te values in gold-bearing structures and hence an important pathfinder element tool for gold mineralization.

Link Between Conquest Gold and Creston Copper Showings

The 2025 drilling program (Figure 2), along with previous drilling, continues to define a “keel-like” zone of near-surface gold mineralization (Figures 3a, b and c), measuring approximately 75 metres-wide, 400 metres-long and 50 metres-deep that is fed, or cross-cut, by the gold-silver-telluride bearing structures. These structures continue to the southwest where they intersect diatreme breccia pipes in the 2 km diameter Creston Porphyry copper anomaly, where soil samples, highly anomalous in Te, overlie the structures (Figure 4).

Epithermal gold and porphyry copper are genetically linked as both are formed from a large magmatic-hydrothermal system. The porphyry copper systems are typically deeper and hotter components of a magmatic-hydrothermal system which evolve upwards to shallower, lower temperature epithermal gold systems.

Creston Copper Porphyry

Recent work points to an underlying polymetallic (Cu-Au-Ag-Mo-Te) porphyry and/or hydrothermal system at Creston. Evidence includes:

1. Chalcopyrite veins and void fillings in diatreme breccia (Figure 5a);
2. Fragments of porphyry-style chalcopyrite-molybdenite mineralization, brought up from depth, by the explosive eruption of a diatreme breccia pipe (Figure 5c);
3. Quartz blebs, hosting native copper (Figure 5c) and porphyry-type quartz veinlets with chalcopyrite, bornite (Figure 5d) within diatreme breccia;
4. The top of a hydrothermal breccia vent anomalous in gold, molybdenite, tellurium and other pathfinder elements (Figure 5e); and,
5. A newly exposed rhyolite porphyry stock which carries fine-grained, disseminated chalcopyrite.

A drill permit application for 14 holes designed to test the Creston Porphyry Target, late in the fall or early winter, is in progress. There are sufficient permitted drillholes in the area of drillhole 25RC-33 to follow up on the results to date and trace out the ginguro textures seen in the epithermal veins, a diagnostic feature in low-sulphidation epithermal deposits.

“While the deeper drillholes mostly intersected strong epithermal alteration, we continue to intersect near-surface gold mineralization in the southern Conquest Zone including the top of the boiling zone in newly identified structures. Having intersected the boiling zone, we can now step the drill back in the next program at Conquest and start following these veins. Based on the trend of these structures and their enrichment in tellurium they may represent the physical link between the epithermal gold and porphyry copper portion of an intact epithermal gold-porphyry copper system.  At the beginning of the year, we indicated that we wanted to advance the copper target at Root & Cellar to the drilling stage and with the recent and on-going discoveries at the Creston Zone, we are there sooner than expected.  We drive by the quarries where the diatreme breccias are exposed, on the way to the drill at Conquest and the evidence became too much to ignore. I said to the prospector, Jeff Brushett, who optioned the Property to us, “if we were in Chile, for instance, and had a 2-km diameter copper anomaly, a diatreme breccia pipe hosting copper, moly, gold and tellurium, surrounded by 5 epithermal gold occurrences, there would be a race to acquire it and drill it. So, let’s drill it and put the Burin Peninsula on the porphyry copper map and attack the system from both ends.”

About Northern Shield Resources

Northern Shield Resources Inc. is a Canadian-based company known as a leader in generating high-quality exploration targets that views greenfield exploration as an opportunity to find a mineable, near surface deposit at relatively low cost. We implement a model driven exploration approach to reduce the risk associated with early-stage projects for ourselves, our shareholders, and the environment. This approach led us to option the Root & Cellar Property from a Newfoundland prospector, who discovered the mineralization, and then saw its advancement to a large gold-silver-tellurium and porphyry copper system.
