NORTHISLE ANNOUNCES INITIAL EXPLORATION PROGRAM

FOR PEMBERTON HILLS UNDER A FARM-OUT OPTION

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

McMoRan Mineral Properties Canada Inc. (“Freeport”) have agreed to an initial work plan and budget for Northisle’s

wholly-owned Pemberton Hills Property located on Vancouver Island, in British Columbia . The program is being fully -

funded by Freeport under a farm-out Option Agreement executed earlier this year and announced by the Company on

February 26 th, 2018. Under the terms of the agreement, which are summarized at the end of this release, Freeport

may earn an initial 49 per-cent interest in the Property by paying CAD50,000 cash to Northisle (paid) and funding a total

of CAD4.0 million in exploration expenditures over three years.

The Pemberton Hills target is a 3.5 kilometre by 1.5 kilometre area of advanced argillic alteration located within the

geological terrain that extends northwest from the past producing Island Copper Mine and in close proximity to the

Company’s wholly-owned development-stage Hushamu and Red Dog copper-gold deposits (see attached map).

The alteration at Pemberton is commonly found overlying porphyry copper deposits and is similar to that observed at

Hushamu and Red Dog . Further evidence of a potential buried porphyry copper deposit at Pemberton is the presence

of anomalous copper intersected at the end of an historical 200 metre deep drill hole within the altered area.

The up-coming work program will consist of approximately 10 K ilometres of Induced Polarization (IP) geophysical

survey and three drill holes totaling approximately 1500 metres. The estimated cost for the program is CAD 700,000.

Subject to the receipt of permits, it is anticipated that the IP survey will begin in late June with drilling to begin in

September once the IP survey is completed and the results interpreted.

John McClintock, President and CEO of Northisle states: “We look forward to getting back on the ground at Pemberton

Hills with funding and technical support of Freeport. Pemberton Hills is one of several early -stage exploration targets

on our extensive property holdings in this impressive copper-gold district.”
