THUNDER BAY, ON / ACCESSWIRE / September 14, 2020 / Wolfden Resources Corporation (TSXV:WLF) ("Wolfden" or the "Company") is pleased to announce the positive results of an independent Preliminary Economic Assessment (the "PEA") for its wholly owned Pickett Mountain high-grade polymetallic project in Northeastern Maine.
The Base Case Financial Model Yields:
- After-tax IRR of 37%
- After-tax NPV8% of US$198 million to Wolfden for an underground mine plan scenario
- Initial capital expenditure of US$147.4 million including 20% contingency and closure costs
- Payback 2.4 years
The PEA financial model used consensus metal prices assumptions of $1.15/lb Zinc, $1.00/lb Lead, $3.00/lb Copper, $18.00/oz Silver and $1,500/oz Gold. Full details of the Preliminary Economic Assessment in the form of a technical report for the purposes of NI 43-101 will be filed on SEDAR within the next 45 days. All financial figures are in US dollars.
"The PEA underscores our belief that the solid economics of the Pickett Mt. Project and its resource are still largely unrecognized by investors and not reflected in the current market capitalization of the company," stated Ron Little President and CEO of Wolfden. "With base metal prices moving higher, these results reaffirm our commitment to increase and upgrade the mineral resources through aggressive exploration and to further de-risk the project with our ongoing pre-permitting efforts and additional technical and baseline studies."
"The Pickett Mountain deposit represents one of North America's highest-grade undeveloped polymetallic deposits with fundamentals that are indicative of a top quartile project, including one of the lowest C1 Costs $0.38/lb zinc (Net Direct Cash Cost) in our sector," stated Jeremy Ouellette Vice President of Project Development. "With this kind of a break-even zinc price, the project can sustain metal price market declines that have not been seen in decades. In addition, the project is extremely well located close to infrastructure and services yet is far enough removed from the nearby towns (10 miles) with a site location that exhibits very low environmental and social impacts. The project is expected to generate over 100 full time jobs and add significantly to the local and state economies."
Summary of Base Case Financials
The PEA for NI 43-101 purposes, is considered preliminary in nature which includes inferred resources within the economic analysis that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. The Base Case assumptions include revenues using $1.15/lb Zinc, $1.00/lb Lead, $3.00/lb Copper, $18.00/oz Silver, $1,500/oz Gold prices. Cost inputs are generally constructed by first principle or by estimates supplied within the region. The financial highlights are as follows:

The PEA was completed by A-Z Mining Professionals Ltd. of Toronto, Canada ("A-Z Mining") and included inputs by ProSolve Consulting Ltd, Mine Paste Ltd., Wood Environment and Infrastructure Inc. and SLR Consulting Ltd., and was based on an updated resource estimate prepared by A-Z Mining of Toronto.
Mineral Resources used in the Mine Plan
The mineral resource used in the PEA includes indicated and inferred resources and is an update from the January 7th, 2019 mineral resource statement. The estimate uses a 7% cutoff grade (or an NSR value of $139/t) rather than the previous 9% cutoff grade ($178/t NSR). The same methodology used in the 2019 estimate was applied to the updated estimate where the metal prices were not updated (to those used in the PEA financial model) and no additional information was either included or excluded. Infill drill results since the 2019 resource estimate are expected to upgrade the mineral resource and could potentially lead to an increase.
Tonnes | Zn % | Pb % | Cu % | Ag g/t | Au g/t | Density | ZnEq % | |
Indicated Resource | 2,177,000 | 9.25 | 3.68 | 1.32 | 96.4 | 0.9 | 3.98 | 18.23 |
Inferred Resource | 2,294,000 | 9.79 | 3.88 | 1.15 | 101.1 | 0.9 | 3.99 | 18.62 |
The mineral resources were estimated using the metal prices of US$1.20/lb Zn, $2.50/lb Cu, $1.00/lb Pb, $16.00/oz Ag, and $1,200/oz/Au, using a 7% cutoff grade that equates to an NSR cut-off of $139/tonne at the same metal prices. An average recovery of 75% for all metals was assumed. A 10% mining dilution at zero grade was only added to the financial model which also used different metal prices. | ||||||||
Estimated Annual Production
Production at Pickett Mountain will be using combined Long Hole Open Stoping and Alimak mining methods. Since the deposit is near surface, ramp up to full production is possible within one year of development and construction. Estimated throughput is 432,000 tonnes per annum (1,200 tonnes per day).
