Vancouver, B.C. – Northisle Copper and Gold Inc. (TSX-V: NCX) (“Northisle” or the “Company”) is pleased to confirm the successful conclusion of its 2021 drilling program at the Pemberton Hills target on its 100% owned North Island Project, as well as a progress update on its ongoing surface exploration program at the Goodspeed and South Macintosh targets.

Pemberton Hills

The objective of this program was to confirm the existence of a large copper, gold, molybdenum bearing porphyry system.  Previously completed induced polarization surveys, clay studies and geological and structural mapping and historical drilling, including a 200 metre deep drill hole ending in 0.14% copper, defined the target for this year’s drill program.

The drill program at Pemberton Hills was initially planned to test the target with 3 drill holes, each with a planned minimum depth of 600m per hole.  All of the holes reached their planned depth and were extended further (see table below).   An additional hole drilled from the same site as the historical hole with copper mineralization tested the area to the northwest of P21-08.

Drill core has been cut and shipped to Bureau Veritas Labs in Vancouver, BC for analysis and results will be released once completed and reviewed.

Red Dog and NW Expo

As previously disclosed, drilling at Red Dog is anticipated to include four drill holes totalling approximately 2,000 metres. The drilling will target both the northwest extension of the higher-grade Red Dog deposit and test for the down faulted south side of the deposit.  The drill program at Red Dog will begin immediately once permits are received.

At NW Expo, the untested portion of a 1.5km long IP chargeability anomaly will be tested with 4 holes totalling 2,000 metres. This drilling will commence immediately upon completion of the drilling at Red Dog anticipated to be during Q3 2021.

Goodspeed and South Macintosh Surface Exploration

The Goodspeed and South Macintosh areas are the highest priority among the multiple porphyry occurrences and high-level porphyry-type altered zones present on the property.

At South Macintosh, recent logging roads exposed a large area of previously unknown high-level porphyry alternation which is the target of a surface mapping program which commenced during May 2021.

At Goodspeed, surface exploration is now underway, with completion during April of soil sampling in the area between Red Dog and the Goodspeed target as well as detailed mapping of Goodspeed.  Drilling at the Goodspeed target in the 1960s and 1990s intersected encouraging copper values including 0.32% over 24 metres, 0.19% over 72 metres, and 0.16% over 42 metres.
