Northisle Copper and Gold Inc. Announces Positive Drill Results
Northisle Copper and Gold Inc. Announces Positive Drill Results
VANCOUVER, British Columbia, Sept. 06, 2017 -- Northisle Copper and Gold Inc. (“Northisle” or the “Company”) is pleased to
report the results from this summer’s drill program on its wholly owned North Island Copper-Gold project on Vancouver Island,
British Columbia.
The program consisted of 1800 metres in six drill holes including testing three exploration targets and collecting a
metallurgical sample for future testing. The program was successful in meeting its three exploration objectives:
1. Test for a southeastern extension of the Hushamu deposit;
2. Test a 300 metre diameter area within the Hushamu resource that was previously thought to be barren;
3. Test for a deeply buried porphyry copper and gold mineralization to the south of the Red Dog Deposit.
Highlights
• The mineralization in H17-05 indicates the Hushamu Deposit is open both to the north and to the southeast.
• Holes H17-02 and H17-03, show conclusively that much of the previously assumed barren area is mineralization above
the cut-off grade.
• Drill hole RD17-01, testing the deep porphyry target at the Red Dog Deposit, encountered high-level porphyry copper
alteration from bedrock to the end of the hole at 290 metres.
• Additional drilling is warranted to further advance all current exploration objectives.
South Eastern Extension Results
Hole H17-05, positioned approximately 300 metres southeast of the final pit limit on the Hushamu deposit as used in
Northisle’s soon to be released Preliminary Economic Assessment (PEA), was collared south of the projected southeast
extension and angled towards it. Due to bad ground conditions, the hole was lost at 225 metres well short of its planned depth
of 400 metres. The hole entered high-level porphyry copper mineralization at 60 metres with copper and molybdenum grades
noticeably strengthened with depth down the hole. The section of the hole below 100 metres assayed above cut-off grade as
defined in the currently underway PEA with the best mineralization occurring in the final 24 metres of the hole. The
mineralization in H17-05 indicates the deposit is open both to the north and to the southeast. Additional drilling will be required
to determine the extent and grade of the mineralization associated with H17-05.

Infill Drilling Within 300 Metre Diameter Area
Drill Holes H17-02, H17-03 and H17-04 tested an under drilled, previously believed to be very low grade or barren part area of
the south central Hushamu deposit. Based on widely spaced vertical historical drill holes, this area had been interpreted to be
an area of late or post mineralization breccia and associated non sulphide bearing silicification. Holes H17-02 and H17-03,
show conclusively that much of the previously assumed barren area is mineralization above the cut-off grade. Hole 17-04,
collared in sulphide mineralized rock traversed post mineralization breccia and silicification before ending in sulphide bearing
porphyry-type mineralization. Additional drilling is required to determine how much of the currently assumed barren 300 metre
area could be added to the Hushamu resource.

Hole H17-01 was a drilled in the central part of the Hushamu deposit to collect a metallurgical sample for future testing.
Target for Buried Porphyry at Red Dog
Drill hole RD17-01 tested the deep porphyry target at the Red Dog Deposit and was collared 600 metres southeast of the
current Red Dog resource and 230 metres from the nearest historical drill hole. Originally planned to reach a target depth of
600 metres, the hole was lost at 290 metres. The hole encountered high-level porphyry copper alteration from bedrock to the
end of the hole at 290 metres. The encouraging alteration and copper values found in the drill hole warrant additional drilling to
a depth of 600 metres to see if a deep porphyry copper deposit is located to the south of the Red Dog deposit.

Based on the success of this summer’s drilling, Northisle plans to carry out systematic drilling to the north and southeast of
H17-05 to determine the limits of the identified southeast extension and additional infill drilling within the south central part of
the Hushamu deposit. Another attempt will be made to test the deep target at Red Dog.
Jack McClintock, P. Eng, President of Northisle commented: “I am extremely pleased with the results of this summer’s drilling
program as they have exceeded my expectations. Drill hole H17-05 has confirmed that the Hushamu deposit is open for a
considerable distance to the southeast and there is potential to significantly expand the resource. The drilling in the south
central part of the deposit shows that much of previously presumed barren leach or lithocap contains appreciable copper, gold
and molybdenum mineralization and if confirmed by future additional infill drilling could both add to the Hushamu resource and
reduce the strip ratio. I am excited that our PEA is nearing completion and will be ready for release within the next two
weeks.”
Analytical Techniques
Analysis of core samples was carried out at BVL Minerals’ (formerly ACME Analytical) Vancouver facility. Gold analysis is by
fire assay methods with atomic absorption finish. Analysis for copper and other metals is by a four acid digestion with ICP
finish. Quality Assurance and Control (QA/QC) included insertion of standards and blanks in to the sample stream and
duplicate samples on quartered core.
The North Island Copper-Gold Project
The North Island Copper-Gold Project is situated approximately 15-40 kilometres southwest of Port Hardy and contains the
Hushamu and Red Dog Deposits and five other partially explored copper-gold porphyry occurrences.
The Hushamu Resource
The Company has a current resource estimate of the Hushamu Deposit which has been filed on Sedar. The project is 100%
owned by Northisle subject to a 10% net profits interest.
