Copper Resource in Canada’s Yukon Territory
This profile is part of a paid investor education campaign.*
Copper North Mining Corp. (TSXV:COL) is a mining exploration and development company committed to becoming a mid-tier copper producer. Copper North Mining is exploring and developing three properties in Canada: Carmacks in the Yukon territory, Redstone in the Northwest Properties, and Thor in Northwest British Columbia.
The Company’s flagship property is the Carmacks Copper Project in the Yukon Territory of Canada. The project has a two NI 43-101 compliant mineral resources. The first was developed as part of the 2016 PEA, and covers the proposed open-pit. The measured and indicated resource in the open pit is of 11.98Mt@ 1.07% copper, 0.456g/t gold and 4.58g/t silver for 282 million pounds of contained copper, 171,800 oz of gold and 1,705,800 oz of silver.
The second resource estimate is for the Southern Extension zones (2000S, 13 and 12) and was updated in 2018. The oxide measured and indicated resource is of 4.3 million tonnes at 0.47 percent copper, 0.12 g/t gold and 1.91 g/t silver. The sulphide measured and indicated resource is of 4.4 million tonnes at 0.62 percent copper, 0.13 g/t gold and 2.3 g/t silver. The company plans to continue drill work in 2018 so as to continue resource expansion.
In 2016, Copper North Mining updated their previous PEA, focusing on the open-pit zones 1, 4 and 7. With a mine life of seven years and a base case of US$2.75 per pound of copper, the mine would have a pre-tax NPV (8 percent) of C$56 million and a pre-tax IRR (8 percent) of 14.2 percent.
Copper North Mining is in the midst of re-designing and re-engineering the production plan at Carmacks in order to complete a new Feasibility Study aimed at reducing capital and operating costs and de-risking the project for permitting.
- High-grade oxide copper deposit with significant recoverable gold and silver
- Early-stage copper-gold-silver sulphide mineral resource
- PEA for the Carmacks Project filed October 2016, NI 43-101 report
- Carmacks Project open-pit Oxide Measured & Indicated Resource of 11.98Mt@ 1.07% Cu, 0.456g/t Au and 4.58g/t Ag for 282 M lbs contained Cu, 171,800 oz Au & 1,705,800 oz Ag.
- Additional Oxide resource of 4.3 million tonnes at 0.47 percent copper, 0.12 g/t gold and 1.91 g/t silver in oxide and 4.4 million tonnes at 0.62 percent copper, 0.13 g/t gold and 2.3 g/t silver in sulphide.
- Yukon Territory, Canada: low political risk jurisdiction, stable tax regime, current exchange rate favourable for investors, and 100% ownership.
- Road accessible with proposed 10 kilometer transmission line to the grid.
- Cathode copper: reduced transportation and treatment expense compared to copper concentrates.
Copper North Mining Flagship Property: Carmacks Copper Project
The Carmacks Copper Project is located 192 kilometers north of Whitehorse and 38 kilometers northwest of the town of Carmacks in Canada’s Yukon Territory. The property lies on the Klondike Highway, has excellent road access and a planned 10 km transmission line to the Yukon power grid. The shipment of cathode copper can be shipped to several sites in Canada and United States.
Mineral Resource and Mining
The following table summarizes the measured mineral resource and indicated mineral resource estimates for zones 1, 4 and 7 that total 11,980,000 tonnes grading 1.07% total copper of which 0.86% is soluble copper. The mineral resource estimates also include substantial gold and silver. The mineral resources in the oxide classification form the basis for the potentially mineable mineralization by open pit methods. The present PEA does not include inferred mineral resources in the economic calculations. The PEA is preliminary in nature and there is no guarantee that any of the mineral resources will be converted to mineral reserves, or that the PEA will be realized.
Mineral Resources at a 0.25% Total Copper Cut-Off, Zones 1, 4, and 7
Preliminary Economic Assessment (PEA)
Copper North Mining released a new PEA in 2016 to reflect the new leach and development plan, and was based on the mineral resources in Zones 1, 4 and 7 that indicate an approximate 7 year mine life based on the mineral resource update reported in January 2016. However, the new mineral resources in zones 2000s, 12 and 13, were not included in the PEA. Instead, the estimated mineral resources in zones 2000S 12 and 13 will be integrated into a later development plan.
Highlights from the PEA (with a base case of US$2.75 per pound of copper) include:
- Pre-tax NPV (8 percent) C$56 million
- Pre-tax IRR (8 percent) of 14.2 percent
- Mine life of seven years with a 4.3 year payback period
- Capital expenditure of C$263 million (including $47 million contingency and sustaining capital)
- Gross LOM revenue of C$450
The PEA report was prepared by JDS Energy and Mining Inc., Vancouver, B.C. and included an equipment list and costing for processing plant equipment. The PEA indicated a list of opportunities for improvement of project economics. Evaluation of these opportunities are in progress and confirm improvements.
Consent pricing copper at US $3.20 lb copper results in increase economic as:
- NPV (PreTax 8% discount) – C $141 Million
- IRR (PreTax 8% discount) – 22.6%
- Mine Life of 7 years with a 3.0 year pay-back period.
Highlights of the Mineral Resource Update:
The 2016 Updated Mineral Resource released with the 2016 PEA outlined a maiden resource for zones 12, 13 and 2000S combined with the previously defined mineral resource for the Carmacks Project as set out in NI 43-101 Mineral Resource (January 25,2016).
Drilling of these mineral zones commenced September 2017 to expand and confirm mineral resource for further engineering to increase mine plan. 2017 drilling covered 4,165 meters of infill and step-out drilling in zones 2000S and 13. Results from the drilling uncovered further oxide mineralization and assay values of 34.9 meters of 0.65 percent copper, 0.14 g/t gold and 2.47 g/t silver, and 50.2 meters of 0.68 percent copper, 0.13 g/t gold and 1.95 g/t silver. Results led to the release of a further updated resource estimate for the new zones, which was published in April 2018 and increased the size of the overall Carmack resource.
