Sam Lee, President and CEO of Northisle commented, "I am delighted with the progress we have made in demonstrating that the North Island Project is one of the most attractive copper and gold development projects today. The 2021 PEA illustrates a significant improvement in the potential of the North Island Project. Copper and gold production increased materially resulting in a significant increase in NPV and IRR, while all-in sustaining costs remain in the first quartile and initial capital is modest for a long-life and significant copper and gold asset. The concentrate planned to be produced by the North Island Project is anticipated to be a premium product which would be highly attractive to global smelters. Furthermore, the significant gold production is anticipated to provide several options for lower cost capital financings. We are excited to be advancing what we believe is one of the most attractive Canadian copper projects during the start of a new mining super cycle. There exists a multitude of opportunities to develop a mine that is truly sustainable in all respects. We are excited to continue our consultation work with First Nations, local communities, governments, and key project stakeholders as we advance this important and compelling project. We have direct access to clean power in British Columbia that will drive our project towards becoming a lower carbon emissions operation. Over the coming months, we will continue to optimize key project parameters to create additional value for shareholders while focusing on reducing the impact of the North Island Project. Exploration activities will also be reactivated in 2021 with an initial drill program focusing on three main areas: Red Dog, Pemberton Hills, and Hushamu. Program objectives include increasing tonnage and grade for the North Island Project, confirming the existence of a larger, higher grade copper-gold porphyry system at Pemberton Hills, and exploring multiple targets over our vast 33,000 ha property. Our leadership team is fully committed to realizing our vision of making Northisle Canada's leading sustainable resource development company." The Company will host a conference call and webcast on Thursday, February 4, 2021 at 11:00 AM Eastern time (8:00 AM Pacific time).

This means that monitoring, disclosing, and improving on ESG performance is as critical as operating metrics. As a result, Northisle has summarized preliminary sustainability metrics for the North Island Project in Table 5 below. Table 5: Preliminary Sustainability Metrics Sustainability Statistics Units LOM Total / Avg. Direct local job creation (permanent) FTE 450 Site Energy Consumption Fuel (annual) 000s liters 21,000 Electricity (annual) MWh 794,000 Energy Intensity kWh/lb Cu 10.5 Environmental Net water consumption liters / lb Cu 99.6 GHG Emissions – Scope 1 kg CO2e / lb Cu 0.66 Total Material to MWF MT 1,020 The above sustainability metrics were determined on a preliminary basis by referencing publicly available benchmarks for emissions related to key project energy sources. The selected metrics will evolve as the project is developed, to incorporate additional measures of ESG performance. Opportunities The PEA demonstrates the potential for further development of the North Island Project and indicates a number of additional opportunities for further study which may contribute to further enhanced value, including: -- Evaluate the opportunity for sale of pyrite concentrate: Preliminary study and test work indicates that a substantial quantity of high-grade pyrite concentrate can be recovered. Additional studies are required to determine the marketability of pyrite concentrate. -- Consider use of historical Island Copper Pit for mine tailings storage: The existing pit at the former BHP Island Copper Operation could potentially be re-purposed to store most of the tailings from the North Island Project development, which represents an opportunity to reduce the risk profile for the project. -- Trolley-assisted haulage: The current project uses electrical power for the mining shovels and drills at Hushamu and an opportunity exists to consider trolley-assisted haulage to reduce emissions from the proposed diesel-electric fleet. -- Reduce carbon emissions: Northisle will conduct an energy audit to evaluate available technologies and best practices to drive the project development towards attaining carbon emission reduction goals. -- Metallurgical optimization: Future test work will target improved recoveries, refined reagent regimes, optimization of grind versus recovery in both primary and regrind circuit to drive lower energy and media consumption while maintaining mineral recovery effectiveness. -- Engineering trade-off studies: Conduct engineering trade-off studies to improve plant performance, reduce operating and maintenance cost and enhance on-line availability as well as opportunities to optimize plant throughput. Next Steps With the completion of the 2021 PEA, Northisle intends to continue to advance the North Island Project. Key next steps and milestones include: -- Commencement of planned 2021 drill program which will include exploration drilling at Pemberton Hills, Red Dog and NW Expo, as well as in fill and step-out drilling at Hushamu -- Additional extensive surface mapping and sampling of several additional prospective porphyry targets (H2) -- Commencement of critical trade-off studies, environmental baseline work and other long-lead items in support of determining the scope of a pre-feasibility study in H2 2021. -- Northisle will continue to proactively engage with First Nations, local communities, government and key project stakeholders in support of the responsible development of the project.

The study was prepared independently by M3 and incorporates results from independent metallurgical testing by SGS and MWF design by Golder, and mine plan developed by John Nilsson. The Company now intends to commence important work to prepare for initiation of a pre-feasibility study, while accelerating the exploration program throughout the property. Mineral Resources Mineral Resources for the Hushamu deposit were updated for the purpose of the 2021 PEA by incorporating 5 drill holes completed in 2017 which had not been incorporated in earlier estimates. These drill holes had the anticipated impact of converting several Inferred blocks into the Indicated category. In addition, the cut-off grade for the resource was revised to 0.10% which had the result of increasing tonnage in both Indicated and Inferred Resources while reducing grade.

Mining Preliminary mine designs have been developed for Red Dog and Hushamu deposits based upon Indicated and Inferred Resources. Resource models were imported to Minesight® mine planning software where a Lerchs Grossman algorithm was applied to an NSR model to determine possible pit limits. The mine plan was developed to mine Red Dog concurrently with Hushamu in the early years of the mine life until Red Dog Resources were depleted. The assumed processing rate is 75,000 t/d; Red Dog contributes 24,000 t/d while in operation. The overall mining rate peaks at 64 million t/a in the initial years averaging 47 million t/a over the total mine life of 22 years. The effective strip ratio after stockpile reclaim was 0.71:1. The mine is planned to be a conventional truck and shovel operation with electrified pit operations at Hushamu. Waste rock will be placed during construction and operation within the MWF. A low-grade stockpile will be located at the pit rim on the northwest side of Hushamu. An overburden stockpile will be located adjacent to the low-grade stockpile for use in reclamation of the MWF at the end of the mine life.

M3 reviewed and interpreted the test work and incorporated the results into the process plant design criteria, flowsheet development, and process equipment selection. The design basis for the processing plant is 75,000 t/d or 27,375,000 t/a at 93% availability. Design mineral grades to the process plant are estimated at 0.18% copper, 0.24 g/t gold and 0.008% molybdenum with overall estimated recoveries of approximately 86.4% for copper, 46.8% for gold, and 59.5% for molybdenum. Operating Cost Summary A preliminary operating cost estimate was prepared for the North Island Project based on a 75,000 t/d mine/mill operation. Total site operating costs are summarized in Table 12. Table 12: Total Site Operating Costs Area Units Cost Mining Cost1 $/tonne processed $3.84 Processing $/tonne processed $5.52 G&A $/tonne processed $0.38 Water Treatment $/tonne processed $0.06 Total Site Operating Costs $/tonne processed $9.81 1. Including leased mining equipment Capital Cost and Infrastructure Summary The capital cost estimate was developed by M3 using an EPCM project development approach. Golder developed a conceptual design for the MWF and provided estimated quantities of construction material required to construct the facility. M3 then estimated the associated initial and sustaining capital cost based on the quantities provided. The mine plan and associated mine initial and sustaining capital was prepared by John Nilsson using current equipment prices and leasing terms & conditions provided by the mine equipment procurement consultant retained by Northisle. The process facilities and other related facilities were designed and estimated by M3. The capital cost of these facilities was developed using budgetary quotes obtained for major process and infrastructure facility equipment requirements, and construction labour rates obtained from a BC contractor experienced in the scope and scale of the North Island Project. The 2021 PEA capital cost estimate is summarized in Table 13 below. Table 13: Capital Cost Summary Area $ million Mine1 17.8 Pre-production 130.9 Process 1,235.4 Owner's Cost 57.9 Total 1,442.0 1. Mine equipment is included primarily on a leased basis in the financial model. The nearby town of Port Hardy is a main distribution centre for the north end of Vancouver Island. It has an airport with regular flights to Vancouver, a hospital, schools, and a college. The North Island Project is generally accessible for exploration purposes from Port Hardy through a network of logging roads. BHP is in the process of reclaiming its historical marine load out infrastructure from its past-producing Island Copper Mine. The 2021 PEA contemplates the construction of a new marine load-out facility on the reclaimed site, which would be used to load concentrate onto ocean-going vessels for shipment to smelters in Asia. One of BC's largest wind farm complexes is situated adjacent to the northwest end of the property and the 138 KV power line connecting the wind farm to the main BC power grid passes immediately north of the North Island Project. The 2021 PEA contemplates connecting to the BC Hydro grid via the existing main substation near the highway into Port Hardy.
