Vancouver, B.C. - Northisle Copper and Gold Inc. (TSX-V: NCX) ("Northisle" or the "Company") is pleased to provide an update on it's 2021 exploration programs. This includes the commencement of an extensive surface exploration program, in-fill and step-out drilling at Hushamu, and the completion of drilling at Northwest Expo and Red Dog.

Sam Lee, President & CEO of Northisle stated "Our ongoing exploration program continues to support our belief that the North Island Project's extensive mineral tenure package has the potential to become a district camp hosting multiple porphyry deposits along a 50km long porphyry trend. There has already been multiple discoveries along this trend including the Hushamu and Red Dog deposits and the adjacent Island Copper Mine owned by BHP. Our exploration efforts in 2021 and beyond are squarely focused on four additional targets all within a 13km distance from our contemplated central processing facility. While we are experiencing delays in receiving assay results due to backlogs at the laboratories, we are delighted to be conducting the final phase of our 2021 drill program at Hushamu and initiating an extensive surface exploration program to refine and identify the drill targets for our 2022 program."

Robin Tolbert, Vice President Exploration of Northisle added "We are encouraged by drilling to date at Northwest Expo. Visual inspection of core has identified large intercepts of silica-clay-pyriteand chlorite-magnetitealteration, which is consistent with that observed at Hushamu, Red Dog, and elsewhere on the property, as well as in historical mining from the nearby BHP Island Copper Porphyry Mine. Assays are pending and we look forward to receiving results during December." He added, "We have received a multi-yearpermit which provides us with the flexibility to complete both the necessary in-filland geotechnical drilling at Hushamu and the drilling of the adjacent Macintosh target. This target represents a 2.4 km by 1.5 km porphyry alteration system 1.4 km south of the Hushamu deposit."

Northwest Expo

Northisle completed drilling at Northwest Expo in October. Based on visual inspection of core as well as proximity to historical drilling, which contained significant intercepts of gold-rich porphyry mineralization, drill holes NW21-03, NW21- 04, NW21-05 and NW21-08 have been prioritized for assay and are anticipated to be received in December 2021.

The objective of the 2021 program at Northwest Expo was to drill test anomalies indicated by limited induced polarization surveys completed in 2012. In addition, a review of historical drilling from 2005 and 2007 identified several intercepts of economically significant gold and copper which are detailed in Table 2. Figure 1 shows the location of 2021 drilling at Northwest Expo in the context of historical drilling. The previous IP geophysics identified a 550 m wide chargeability anomaly (>15mV/V) extending south from a line running northeast from 5619500 North, north of DDH EC245 to 571400 East, northeast of DDH NW21-02. This is open to the north. The IP/Mag survey commencing shortly will cover that unsurveyed area.

The lithologies intersected in the historic holes above and in NW21-03 consist of strongly altered Jurassic Bonanza Formation volcaniclastics and flows intruded by several felspar-porphyry,hornblende-felspar porphyry dykes, silicified breccias and exsolution textures interpreted as occurring at the upper levels of a porphyry system. All the drill holes listed in Table 1 intersected silica-clay-pyrite (SCP) alteration in the upper parts of the holes, then entered long intervals of mineralized chlorite-magnetite-chalcopyrite (CMG) alteration. CMG,a major component of the mineralization at Northisle's Hushamu and Red Dog Deposits, is observed at the surface at Northisle's Goodspeed prospect, as well as occurring in the Island Copper Porphyry Deposit.

Several additional holes were drilled during the 2005 and 2007 campaigns; however, these were drilled primarily to the south of the 2021 target area and intercepted SCP alteration. SCP alteration commonly occurs in the upper levels of traditional porphyry system models and, in the North Island Project area, tends to be enriched in molybdenum. Notably, at Hushamu, SCP is a significant component of the resource.

2021 drill holes NW21-03 to 05 were drilled in a fan to the southwest, southeast and east. NW21-03 intersected 129 m of CMG from 288m to 417m, similar in alteration and mineralization styles to EC218, 228, 233, 234 and 245. NW21-04 and 05 intersected SCP and long intervals of exsolution textures consisting of clay altered pyritic globules in a dark, fine- grained silica matrix. Drill holes NW21-06 and 07 intersected a major fault zone and were abandoned. The drill was moved 20 metres NE and NW21-08 intersected SCP alteration and encountered porphyry-style stockwork pyrite veining at depth. It was terminated in a late dyke. Collar details of the 2021 drill holes can be found in Table 3 below.

The observed styles of alteration and mineralization in drill holes at Northwest Expo are consistent with Northisle's current hypothesis that this porphyry system is tilted to the southwest so that the core of the porphyry system lies to the northeast.

Red Dog

At Red Dog, drill hole RD21-01 was targeted to test SCP alteration at depth to the south of a major east-west trending fault zone and to drill through the fault and underneath the Red Dog deposit which consists of a mineralized silica- magnetite breccia. The objective was to find the source porphyry for this mineralization. This drill hole encountered SCP alteration but no porphyry on either side of the fault. RD21-02 was drilled to test an IP chargeability anomaly northwest of the Red Dog deposit. The anomaly was found to be caused by SCP and propylitic alteration occurring from near surface to over 300 m depth in the hole. The hole ended in late basalt and felspar-porphyry dykes. Upon completion of these holes, and following reinterpretation and a new hypothesis that this deposit is tilted to the southwest the decision was made to prioritize drilling at Northwest Expo and to complete a more extensive IP survey in the northeast part of the Red Dog system in order to better target drilling.

Assays for all of the above-noted 2021 Northisle holes are pending with first results expected in December.

Hushamu

Drilling at Hushamu has now commenced, following receipt of a multi-year (MYAB) permit which was updated to incorporate all work anticipated for a pre-feasibility study on the Hushamu and Red Dog deposits. The objective of the multi-year drill program of over 79 holes is to upgrade those portions of the deposit that are defined as inferred to indicated or better resource categories in addition to testing areas near the defined resource with potential for increasing the global resource. With drilling occurring later in the season than originally anticipated, drilling will take place at higher elevations and then may move to lower elevations of the deposit, depending on weather conditions.

The Macintosh target, included within the MYAB permit area for Hushamu will be evaluated by TerraSpec clay analysis and Simcoe IP/Mag geophysics to provide targets for drilling in Q1 2022.

Surface Exploration

Northisle has retained Simcoe Geoscience Limited ("Simcoe") to undertake a staged geophysical survey covering multiple porphyry-style targets at the North Island Project. This program seeks to provide along with TerraSpec clay analyses district-wide targets for 2022 drilling. Simcoe uses the innovative Alpha IPTM system, which provides the ability to complete IP surveys while minimizing the impact on the environment by eliminating the need for traditional line-cutting.

Simcoe will also be completing a ground magnetic survey and will provide 2D and 3D inversions of the induced polarization data which will be integrated with previous IP, surface mapping, drilling and TerraSpec clay analyses.

Details of the program are subject to change but are currently contemplated to include more than 60 line kilometers covering the Pemberton Hills, MacIntosh, Goodspeed, Red Dog and Northwest Expo areas. This program is expected to be completed by Q2 2022.

Simultaneously, Northisle personnel will be completing geological mapping and surface sampling across the same target areas to integrate geology, clay mineralogy and rock geochemistry with geophysics in order to generate targets for follow- up drilling commencing in 2022.
