Vancouver, B.C. – Northisle Copper and Gold Inc. (TSX-V: NCX) (“Northisle” or the “Company”) is pleased to announce that it has filed on SEDAR an independent technical report (the “Report”) prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) titled “North Island Copper and Gold Project NI 43-101 Technical Report Preliminary Economic Assessment” supporting the results of a Preliminary Economic Assessment (the “2021 PEA”) on the Company’s North Island Project. The results of the 2021 PEA were previously reported in the Company’s news release dated February 4, 2021 and there are no material differences in the Report from those results. The effective date of the Report is March 18, 2021.
2021 PEA Highlights
- The 2021 PEA confirms that the North Island Project is one of the most attractive copper-gold porphyry projects in Canada:
- Long mine life of 22 years with average annual production of 177 mm lbs Cu Eq. over the first 6 years, including 112 mm lbs of copper, 112 koz of gold and 2.7mm lbs of molybdenum
- Average annual after tax free cash flow of $321 million during the first 6 years and $224 million over the life of the operation
- First quartile AISC of $0.77/lb Cu (net of by-products) and $2.01/lb Cu Eq. over first 6 years
- Attractive economics with $1.1 billion After-tax NPV (8%) and 19% After-tax IRR
- Attractive payback of 3.9 years driven by modest capex of $1.4 billion due to excellent infrastructure from historical mining and other industrial activity
- Northisle is committed to sustainable mine development:
- Northisle will pursue a collaborative, inclusive approach to consultation in order to develop a project which creates benefits for First Nations, local communities, shareholders and project stakeholders
- The Project benefits from renewable BC power and the Company will investigate multiple opportunities to reduce overall impact including electrified mining operations as part of trade-off studies
- Multiple opportunities to further improve the Project through optimization and exploration with prospective targets at Pemberton Hills, Red Dog and Hushamu; 2021 drilling program has commenced
The 2021 PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the project described in the 2021 PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
Key performance indicators are summarized in Table 1 below.
