NORTHISLE BEGINS EXPLORATION AT ITS PEMBERTON HILLS TARGET

HIGHLIGHTS

• Exploration has commenced on the Pemberton Hills target after a farm-out agreement was formed earlier this

year with Freeport-McMoRan Mineral Properties Canada Inc. (“Freeport”)

• The Pemberton Hills target is a 3.5km by 1.5km area of advanced argillic alteration similar to that observed at

Northisle’s 100%-owned Hushamu and Red Dog copper-gold deposits

• The presence of anomalous copper intersected at the end of an historical 200 metre deep drill hole, within the

altered area, suggests evidence of a buried porphyry copper deposit at the Pemberton Hills target

• The initial exploration program will consist of approximately 10km of Induced Polarization geophysical survey

and 1,500 metres of diamond drilling

Vancouver, B.C. – Northisle Copper and Gold Inc. Inc. (TSX -V:NCX) (“Northisle” or the “Company”) is pleased to

announce that exploration has commenced on its Pemberton Hills Property located on Vancouver Island, in British

Columbia. Northisle entered into a farm -out agreement with Freeport-McMoRan Mineral Properties Canada Inc.

(“Freeport”) earlier this year.

John McClintock, President and CEO of Northisle states: “ We are excited to launch this first exploration program on the

Pemberton Hills target with the funding and technical support provided by Freeport. The alteration at Pemberton is very

similar to what we see at our Hushamu and Red Dog deposits and in porphyry copper systems found elsewhere in the

world. Furthermore, w e already have evidence of a buried porphyry copper deposit as demonstrated by anomalous

porphyry copper mineralization found at the end of an historical hole drilled within the altered area.”

As shown in the figure below, the Pemberton Hills target is a 3.5 kilometre by 1.5 kilometre area of advanced argillic

alteration located within the same geological terrain that extends west -northwest from BHP Billiton’s past producing

Island Copper Mine. The presence of anomalous copper intersected at the end of an historic 200 metre deep drill hole,

within the altered area, suggests evidence of a buried porphyry copper deposit.

This initial exploration program on the Pemberton Hills Property will consist of approximately ten kilometres of Induced

Polarization (IP) geophysical survey and 1 ,500 metres of diamond drilling in three holes, for an estimated cost of CAD

700,000. The IP survey is expected to be completed by the end of September with drilling to start in early October

following interpretation of the survey data.

A farm-out agreement was formed with Freeport earlier this year, dividing the initial property held by Northisle as

illustrated in the figure above . Under the terms of the agreement, as announced on February 26, 2018, Freeport may

earn up to a 65% interest in the Pemberton Hills Property by funding a total of $23.9 million in exploration expenditures,

while Northisle retains a 100% interest in its Hushamu and Red Dog copper -gold deposits and surrounding areas , for

which a Preliminary Economic Assessment was published on September 13, 2017.
