Northisle Announces Drill Results at Red Dog
Identify Emerging High-Grade Trend in Eastern Portion of Deposit
Eastern extension of mineralization beyond 2025 PEA pit shell with multiple significant intercepts including
216.0 metres at 0.67% Cu Eq., including 64.1 metres at 1.10% Cu Eq., and 163.4 metres at 0.86% Cu Eq.
Highlights:
• Drilling at Red Dog accomplished three core objectives:
o Infill drilling within the western, shallower core of the deposit has confirmed the consistency and
reliability of historic drilling results.
o Drilling in the central portion of the deposit confirmed mineralization consistent with the existing
resource model and will support improved confidence in future estimates
o Drilling in the eastern portion of the deposit demonstrated a new, high-grade zone extending past the
limits of the currently modelled resource, indicating potential for resource expansion
• Selected copper-equivalent assay intercepts include:
o RD26-29: 141.4m grading 0.97% Cu Eq. from 3.6m and 70.0m grading 0.88% Cu Eq. from 159.0m, with
multiple higher grade sub-intervals
o RD26-30: 216.0m grading 0.67% Cu Eq. from 156.0m, including 64.1m grading 1.10% Cu Eq. from 288.0m
o RD26-33: 126.0m grading 0.89% Cu Eq. from 177.0m, including 30.0m grading 1.65% Cu Eq. from 222.0m
o RD26-35: 163.4m grading 0.86% Cu Eq. from 165.6m, including 18.0m grading 1.58% Cu Eq. from 185.0m
and 33.0m grading 1.11% Cu Eq. from 230.0m
• Additional exploration drilling commenced on May 29, 2026, with approximately 14,500 metres planned for the
remainder of the 2026 program
Vancouver, B.C. – Northisle Copper and Gold Inc. (TSX-V: NCX, OTCQX: NTCPF) (“Northisle” or the “Company”) is
pleased to announce the results of drilling at the Red Dog deposit in 2025 and early 2026. A total of 8,112 metres of
drilling were completed, including infill, geotechnical, and exploratory drill holes.
Drilling at Red Dog has achieved several important objectives. Infill drilling within the western, shallow core of the
deposit has confirmed previous drilling results and further validated the presence of shallow, higher -grade
mineralization in the deposit. Results from the central portion of the mineral resource were also consistent with the
existing resource model and are expected to support increased confidence in the current resource estimate.
Perhaps most significantly from an exploration perspective, drilling in the eastern portion of the deposit identified a
previously unrecognized high -grade trend at depth. Historic drilling at Red Dog was largely focused on shallow
mineralization, and these results highlight the potential for additional areas contai ning economic -grade
mineralization that have not yet been incorporated into existing resource models.
As a result of the successful drilling program and the potential to improve ongoing technical work with additional
mineralization from Red Dog, the Company is now incorporating the Red Dog drill results in the integrated resource
estimate and subsequently into the ongoing pre-feasibility study work.
Sam Lee, President & CEO noted “Exploration at Red Dog has demonstrated very strong grades over wide intervals,
both near surface and at depth, and has identified a new mineralized domain in a previously under-drilled area. We
are only scratching the surface of the potential of this dist rict-scale opportunity and will be initiating further drill

programs imminently. These important results have the potential to contribute to an improved project and , as a
result, we have taken the necessary steps to allow inclusion of the new Red Dog mineralization in the PFS.”
Pablo Mejia, Vice President, Exploration added “These results from Red Dog represent some of the most significant
geological outcomes of Northisle’s ongoing exploration program, with drilling confirming the potential for additional
mineralization below the current resource envelope and that higher -grade mineralization is not restricted to the
shallow core of the deposit . Critically, the use of Scan technology (by Veracio) , combined with our improved
understanding of the North Island Project mineralized systems, contributed to this important outcome.”
Discussion of Drill Results
A total of 8,112 metres of drilling were completed at the Red Dog Deposit between 2025 and early 2026. The program
was designed primarily to support the ongoing PFS through resource conversion, while also advancing metallurgical,
geotechnical, and exploration objectives. Of the drilling completed, approximately 5,259 metres were dedicated to
infill drilling, aimed at upgrading portions of the current Mineral Resource from the Inferred category to the Indicated
category. In addition, 591 metres were drilled in two holes to provide material for metallurgical testing, 515 metres
supported geotechnical studies, and approximately 2,338 metres targeted resource expansion and exploration
opportunities. A total of 31 holes were completed during the program, with mos t drilling focused on the eastern
portion of the deposit where additional drill density was required to improve resource confidence and support future
mine planning.
The primary objective of the infill drilling program was to increase confidence in the continuity and distribution of
mineralization within the current resource model. Several holes were specifically designed to validate geological
interpretations and confirm grade continuity within areas already classified as Indicated resources. Notably, RD26-
29 returned 141.4 metres grading 0.97% Cu Eq. from 3.6 metres, including 76.0 metres grading 1.02% Cu Eq. from
61.0 metres, while RD26-32 intersected 142.5 metres grading 0.67% Cu Eq. from 6.0 metres, including 36.0 metres
grading 0.98% Cu Eq. from 19.0 metres. Both holes were drilled within the core of the deposit, where historical
drilling density is highest and resources are already classified as Indicated. Core from both holes is also being used
as part of the ongoing metallurgical testing program. The results demonstrate excellent continuity of both
mineralization and grade distribution, providing additional confidence in the geological interpretation and resource
model that underpin the ongoing PFS.
Additional drilling was completed in areas of the deposit where wider drill spacing limited resource confidence and
geological interpretation. These holes were designed to test continuity between existing intercepts while reducing
local gaps within the res ource model. Results confirmed the presence of broad and continuous mineralization
across these areas, including 47.0 metres grading 0.61% Cu Eq. from 4.5 metres, including 29.5 metres grading
0.80% Cu Eq. from 4.5 metres, in RD26 -19; 109.3 metres grading 0.43% Cu Eq. from 36.0 metres, including 20.0
metres grading 0.58% Cu Eq. from 58.0 metres, in RD26-21; 55.1 metres grading 0.33% Cu Eq. from 232.9 metres in
RD26-25; and 22.2 metres grading 0.94% Cu Eq. from 16.8 metres and 154.5 metres grading 0.48% Cu Eq. from 49.5
metres, including 24.9 metres grading 0.70% Cu Eq. from 51.1 metres, in RD26-38. Geotechnical holes RDGT25-01
and RDGT25-02 were also positioned to evaluate mineralization continuity while providing important geotechnical
information for future engineering studies. These holes returned 51.6 metres grading 0.48% Cu Eq. from 2.4 metres,
including 7.6 metres grading 0.84% Cu Eq. from 2.4 metres, in RDGT25-01 and 109.0 metres grading 0.38% Cu Eq.
from 52.0 metres, including 10.0 metres grading 0.84% Cu Eq. from 73.0 metres, in RDGT25 -02. Together, these
results further support the continuity of mineralization throughout the Red Dog resource area and provide additional
confidence for future resource modelling and mine planning.
Beyond resource conversion, several holes were designed to test the down -dip continuity of mineralization below
the current resource envelope in the eastern portion of the deposit, where the recent infill drilling had identified
higher-grade mineralization at depth. The identification and follow -up of these higher-grade zones were enhanced
by the use of Veracio's Scan technology, which provided near real-time geochemical information and helped guide

geological interpretations during the program. Results from RD26 -30, RD26-33, RD26-35, RD26 -36 and RD26 -37
confirmed the presence of a broad and continuous mineralized trend extending below areas targeted by much of
the historical drilling. Highlights include 216.0 metres grading 0.67% Cu Eq. from 156. 0 metres, including 64.1
metres grading 1.10% Cu Eq. from 288.0 metres, in RD26-30; 126.0 metres grading 0.89% Cu Eq. from 177.0 metres,
including 30.0 metres grading 1.65% Cu Eq. from 222.0 metres, in RD26-33; 163.4 metres grading 0.86% Cu Eq. from
165.6 metres, including 18.0 metres grading 1.58% Cu Eq. from 185.0 metres and 33.0 metres grading 1.11% Cu Eq.
from 230.0 metres, in RD26 -35; 102.3 metres grading 0.49% Cu Eq. from 211.7 metres, including 40.4 metr es
grading 1.06% Cu Eq. from 317.0 metres and 13.4 metres grading 1.68% Cu Eq. from 344.0 metres, in RD26-36; and
109.0 metres grading 0.57% Cu Eq. from 362.0 metres, including 29.5 metres grading 0.91% Cu Eq. from 392.0
metres, in RD26-37.
These results represent one of the most significant geological outcomes of the program. Historical drilling at Red
Dog largely focused on the shallower portions of the system, with limited drilling evaluating the continuity of
mineralization at depth. The new drilling confirms that mineralization extends well below the historically defined
resource envelope and that higher -grade mineralization is not restricted to the shallow core of the deposit. The
consistency of both broad mineralized intervals and highe r-grade zones across multiple drill holes suggests the
presence of an emerging eastern high -grade trend and highlights the potential for additional mineralized domains
beyond those currently incorporated into resource models.
Exploration drilling completed outside the principal infill areas yielded mixed results. Holes RD25 -03 and RD26-39
were designed to evaluate the lateral and vertical extent of mineralization beyond the current resource envelope
and provided important geological information for future targeting. While RD26-39 intersected 39.0 metres grading
0.46% Cu Eq. from 276.0 metres, including 18.0 metres grading 0.65% Cu Eq. from 294.0 metres, the hole did not
identify a significant extension comparable to those encoun tered within the central and eastern portions of the
deposit. Similarly, several shallow holes drilled in the northeastern portion of the deposit (RD26-17, RD26-18, RD26-
22 and RD26 -26) returned limited mineralization, suggesting that the shallow northeastern sector may be less
prospective than other portions of the system. In contrast, RD26-31 intersected 19.5 metres grading 0.27% Cu Eq.
from 5.4 metres, demonstrating that shallow mineralization remains locally developed within the north -central
portion of the deposit and identifying an area that may warrant additional follow-up drilling to better define its extent
and continuity.
The results of the 2025-2026 drilling program provide strong support for both resource conversion and future growth
opportunities at Red Dog. The program successfully achieved its primary objective of increasing confidence through
infill drilling while sim ultaneously identifying a deeper high-grade mineralized trend in the eastern portion of the
deposit. With mineralization now outlined over approximately 800 metres of strike length and more than 400 metres
of vertical extent , the continuity of broad minera lized intervals and higher -grade zones supports the potential for
future resource growth and suggests that the mineralized footprint of the deposit remains open for expansion at
depth and toward the east. These results continue to improve the Company’s understanding of the Red Dog system
and reinforce its potential as an important component of the North Island Project.

Note on equivalent calculation for Red Dog:
Copper equivalent grade is determined by calculating total contained metal value per tonne, adjusted for recoveries, if known, dividing by
the copper price, and then dividing the resultant number of pounds of copper by 2,204.6.Gold equivalent grade is determined by calculating
total contained metal value/tonne, adjusted for recoveries, if known, dividing by the gold price, and then multiplying the resultant number of
troy ounces of gold by 31.103. Analyzed metal equivalent calculations are reported for illustrative purposes and consider 80% recovery for
gold, 80% recovery for copper, and assume 80% recoveries for Molybdenum and Rhenium as metallurgical testing has not yet been
completed for these two elements on material from the Northwest Expo deposit.
Gold and copper equivalent calculations based on the following metal prices, which were used in the Company’s 2025 Preliminary
Economic Assessment for the North Island Project: Cu = US$4.20/lb, Au = US$2,150/oz, Mo = US$21/lb, Re = US$1,950/kg. Intervals were
selected based on continuous intercepts with Cu grade above 0.1% Cu or Au grade above 0.1g/t Au. Totals may not add due to rounding.
Intervals are drill intersections and not necessarily true widths. True widths cannot be provided at this time due to the uncertainty in the
geometry of the mineralization. Drill intersections have been selected and composites calculated independently by Northisle. The locations
and distances highlighted on all maps in this news release are approximate.

Note on Red Dog holes:
Holes RD25-04 through RD25-11 were drilled in the West Goodspeed area and their results were previously reported in Northisle's news
release dated November 17, 2025. Hole RD26-34 was abandoned due to challenging ground conditions before reaching its target depth.
Hole RD26-23 was terminated early following a reinterpretation of the geological model and target priorities based on information available
at the time, allowing the program to focus on higher-priority targets elsewhere within the deposit.
