Northisle Announces Near Surface Intercepts and Higher-Grade Intercepts at
Depth at West Goodspeed on its North Island Project
Highlights:
• Recent drilling at West Goodspeed supports the presence of wide intervals of copper-gold-molybdenum-
rhenium mineralization within previously untested portions of the West Goodspeed mineralization outline.
• Selected copper equivalent assay intercepts (based on Cu, Au, Mo and Re assays) include:
o GS25-17: 47.5m grading 0.70% Cu Eq. from 155m, within 70m grading 0.58% Cu Eq. from 145m
plus 34m grading 0.48% Cu Eq. from 71m within 82m grading 0.40% Cu Eq. from 59m
o GS25-18: 19m grading 0.96% Cu Eq. from 303.5m, within 72.5m of 0.54% Cu Eq. from 282.5m,
which also included 15m grading 0.59% Cu Eq. from 340m.
▪ This hole also intersected 20m grading 0.42% Cu Eq. from 260m, within 35m grading 0.35%
Cu Eq. from 245m, and 10m grading 0.36% Cu Eq. from 215m

36m grading 0.32% Cu Eq. from 90m and 15m grading 0.33% Cu Eq. from 294m
• As of June 26, 2025, Northisle has now completed a total of 5,126 metres of drilling including 3,550 metres
in the West Goodspeed and Red Dog area, and an additional 1,515 metres at the Cougar target, located
approximately 1.5 kilometres northeast of the Northwest Expo deposit.
Vancouver, B.C. – Northisle Copper and Gold Inc. (TSX-V: NCX, OTCQX: NTCPF) (“Northisle” or the “Company”) is
pleased to announce initial results from its 2025 exploration campaign, with four drill holes at the West
Goodspeed target and the successful mobilization of a Scan by Veracio mobile XRF scanning system to the North
Island Project. The results, and the addition of the scanning system, represent key steps in Northisle’s 2025
exploration strategy, focused on increasing higher-margin resources in the Northwest Corridor and accelerating
target generation across the 35-kilometre North Island Project porphyry belt.
Sam Lee, President and CEO stated “Drilling at West Goodspeed continues to reinforce the potential for near-
surface deposits in the Northwest Corridor. We are encouraged by the continuity of mineralization, including in the
higher-grade zones at depth. The intercepts observed in multiple holes underscore the strength of the system
outlined at West Goodspeed during the 2023 and 2024 campaigns and the growing understanding of the
mineralized system in this area.”
Discussion of Drill Results
Initial results from the current drilling campaign at West Goodspeed confirm the presence of copper-gold
mineralization extending from shallow levels to depths of approximately 250 metres below the surface.
Preliminary interpretation suggests that mineralized intervals are wider in the northwest sector compared to the
eastern portion of the target area, consistent with 2024 drilling results. Notably, hole GS24‑10 intersected
210 metres of consistent mineralization from near surface, including a 68 metres interval of higher-grade material
(see news release dated August 19, 2024). These results show above average length-grade profiles for both copper
and gold compared to the drilling results obtained in 2024 at West Goodspeed.

While the geometry of the mineralized zone remains under evaluation, the drilling core seems to indicate a
structurally controlled system bounded by two NW-SE–oriented faults spaced approximately 250 metres apart.
Copper and gold grades appear to be concentrated within this corridor. All four reported holes show evidence of
internal dynamic fabric and brittle deformation textures, suggesting that the mineralization was influenced by
post-mineralization fault activity. In several cases, post-mineralization dykes were observed cross-cutting the
mineralized zones, potentially affecting local continuity within the fault-bounded system.
Selected intervals from holes GS25-17 through GS25-20 are summarized in Table 1 below.

Note on equivalent calculation for West Goodspeed:
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 2204.6. 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 only and assume 100%
recoveries as metallurgical testing has not yet been completed on material from the West Goodspeed target.
Copper and gold equivalent calculations based on the following metal prices which were used in the Company’s 2025 Preliminary Economic
Assessment for North Island: 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 a copper grade above 0.1% Cu or a gold 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.
Collar locations for the drill holes are detailed in Table 2. There are no material drilling, sampling, recovery, or
other factors known that could materially affect the accuracy or reliability of the assay data.

Scan by Veracio Unit Mobilized to Enhance Real-Time Decision Making
A Scan by Veracio mobile scanning system has been mobilized to the North Island Project. This unique, patented
technology delivers rapid, high-resolution scanning and multi-element geochemistry of drill core in near-real time.
By providing timely access to verifiable geological and geochemical data, Scan by Veracio enables the Northisle
team to make timely, informed decisions during active drilling. This includes refining drill targeting, adjusting hole
orientations, and reallocating meterage based on live results, ultimately increasing the efficiency of the program
while reducing delays and operational costs.
Pablo Mejia, Vice President Exploration stated “The addition of the Scan by Veracio mobile XRF device is
anticipated to support Northisle’s ongoing exploration program by improving our real-time decision making
through near-instantaneous feedback on drill core. In addition, we will be scanning previously drilled core from the
2025 program as well as previous years to gain a better understanding of the mineral composition. XRF scanning
has been a valuable tool at the North Island Project, and we look forward to leveraging this technology to further
enhance our efforts.”
The Scan by Veracio unit, which is about the size of a cargo van, contains sophisticated software and XRF scanning
equipment that analyzes drill core to detect and measure copper, molybdenum and other associated elements.
Each element present in a sample produces a set of characteristic fluorescent X-rays (a fingerprint) that is unique
to that specific element.

Additional Technical Details
Logging, Sampling and Assaying Procedures and QA/QC
The diamond drill core logging and sampling program was carried out under a rigorous quality assurance / quality
control (QA/QC) program. Drill intersections in this release are typically HQ to 150 metres and NQ thereafter to the
end of holes. After drilling, core was logged for geology, structure, and geotechnical characteristics utilizing MX
Deposit —core logging software, then marked for sampling and photographed on site. The cores for analyses were
marked for sampling based on geological intervals with individual samples of 3-metre length or less. Drill core was
cut lengthwise in half with a core saw. Half-core was sent for assays reported in this news release. Prior to cutting
core for assay bulk density was also determined on site by taking 15 to 20-centimetre (cm) length of whole core of
each lithology at 10-metre intervals. The ends of these were then cut at right angle to the core axis, retaining all
pieces to be returned to the core box for later sample cutting and analysis. The diameter of each core sampled for
bulk density was measured at each end with digital calipers to 3 decimal places and recorded. The length of the
core was measured on four sides at 90 degrees to each other, to 2 decimal places and recorded. The software
Northisle Copper and Gold Inc. | 14th Floor – 1040 West Georgia St. | Vancouver, BC | V6E 4H1
www.northisle.ca | [email protected]
averaged the lengths and diameters. The mass of the dry core was measured twice on an Ohaus© balance to 2
decimal places. If no discrepancy occurred, the measurement was recorded. If there was a discrepancy the
measuring was repeated until no discrepancy between 2 measurements occurred. The density was calculated
using the formula Bulk Density = π times r² times h (where r is radius of core and h is length of core). Certified
standard masses are used to calibrate the scale balance used for bulk density determinations. The balance in the
core logging area was levelled on a large concrete block to avoid vibration, and surrounded by a wooden partition
to avoid wind affecting the balance. The measurements were recorded in MX Deposit and Bulk Density calculated
to 2 decimal places.
A total of +7% assay standards or blanks and +3% core duplicates are included in the sample stream as a quality
control measure and are reviewed after analyses are received. Standards and Blanks were obtained from CDN
Resource Laboratories, Langley, British Columbia. Blanks were obtained from unmineralized course bagged
limestone landscaping rock. Standards and blanks in 2025 drill results to date have been approved as acceptable.
Duplicate data add to the long-term estimates of precision for assay data on the project and precision for drill
results reported is deemed to be within acceptable levels. Samples were sent to the MSALABS in Langley, British
Columbia, where the samples were dried, then crushed, split and a 250-gram (g) split was pulverized to 85%
passing -200 mesh (-75 micrometres (µm)) size pulps. Clean crush material was passed through the crusher, and
clean silica was pulverized between each sample. The pulps were analyzed for gold by fire assay fusion of 50 g of
the 250 g split. Total gold content was determined by digesting the silver doré bead from the fusion and then
analysing by AA (MSA Code FAS-121). All samples were also analyzed for multiple elements by taking a 0.25 g of
the 250 g split which was heated in HNO3, HClO4 and HF to fuming and taken to dryness. The residue was
dissolved in HCl and then analyzed utilizing ICP-MS (MSA Code IMS-230). Any sulphur analysis from this latter
analysis with a value greater than 10% was reanalyzed utilizing a Leco sulfur analyzer. Iron and Tungsten
accelerators are added to the sample and a stream of oxygen is passed over the sample in the induction furnace.
As the sample is heated, sulfur dioxide released from the sample is measured by an IR detection system and the
Total Sulphur content is determined. (MSA Code SPM-210). MSALABS (Langley) is an independent, international
ISO/IEC 17025:2005 accredited laboratory.
Pulps and rejects of holes with significant assay intervals are stored at Western Mineral Storage. The remaining
split core is indexed and stored at the Company’s logging and office facility in Port Hardy, BC.
