Northern Shield Continues to Advance their
Discovery of a Large Epithermal Au-Ag-Te and
Porphyry Cu-Mo-Au-Te System, Root & Cellar
Property, Newfoundland
OTTAWA, ON
,
Oct. 20, 2025
/CNW/ - Northern Shield Resources Inc. ("
Northern Shield
" or the
"
Company
") (TSXV: 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 ("
Root
& Cellar
" or the "
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).

exhibit well developed ginguro bands along contact. (CNW Group/Northern Shield Resources Inc.)
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.
Figure 5. a) Chalcopyrite vein following rhyolite veinlet within diatreme breccia; b) Porphyry-type Cu-
Mo mineralization in fragment within diatreme breccia pipe. The presence of this fragment suggests
the existence of a porphyry copper system at some depth below the diatreme pipe; c) Native copper
rimming quartz bleb; d) translucent quartz veins hosting chalcopyrite and bornite; e) Molybdenite and
pyrite mineralization in hydrothermal breccia hosted within the diatreme breccia pipe. (CNW
Group/Northern Shield Resources Inc.)
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.
