– Total Resources have been increased from 22,554 kt1 (including 1,4171 kt of Reserves) to 24,105 kt with a resulting change in Cu Metal Resources from 7122 Mlbs (including 602 Mlbs of Reserves) to 727 Mlbs; Au Metal Resources from 394 koz (including 312 koz of Reserves) to 396 koz; Ag Metal Reserves and Resources from 3,5522 koz (including 3032 koz of Reserves) to 3,947 koz.
– Economic model presented in the Technical Report evaluates Minto NPV after tax using 8% discount rate of USD$84 million (using long term copper price at $3.10 per pound and USD CAD exchange rate of 1.315)
– Average annual production of 38 million lbs and average annual EBITDA in excess of US$40 million between 2021 and 20253
– Using a flat copper price of US$4.50 per lb over the life of mine and USD CAD exchange rate of 1.250, the Minto NPV after tax using 8% discount rate is USD$265 million3
– C1 cash Cost per lb of Cu is US$2.20
– All In Sustaining Cost (AISC) per lb of Cu is USD$2.65 for life of mine after by-product credits and before closure costs

43-101 Preliminary Economic Assessment Report Resources
In February 2021, JDS Engineering & Mining Inc. (“JDS”) was commissioned by Minto to prepare a Technical Report, which updates the results of the Competent Person’s Report commissioned by Pembridge and delivered in June 2019 with mineral deposits assessment as at 31 May 2019.
The Technical Report confirms the following Mineral Resources as at 31 March 2021:
Total Resources have been increased from 22,554 kt1 (including 1,4171 kt of Reserves) to 24,105 kt with a resulting change in Cu Metal Resources from 7122 Mlbs (including 602 Mlbs of Reserves) to 727 Mlbs; Au Metal Resources from 394 koz (including 312 koz of Reserves) to 396 koz; Ag Metal Reserves and Resources from 3,5522 koz (including 3032 koz of Reserves) to 3,947 koz. Production at Minto restarted in October 2019 with the following table showing the change in Reserves and Resources after considering production for the period from restart to 31 March 2021:
According to the Canadian Institute of Mining the public disclosure of a Mineral Reserve must be demonstrated by a Pre-Feasibility Study or Feasibility Study and therefore the Technical Report identifies Minto’s mineral deposits as Resources only.
The Resources modelled in the Technical Report were based on an 8 year mine life. Given the utilisation of only 45% of the total Resources in the projected 8 year mine life and the fact that inferred resources lack sufficient drilling and mine planning and the significant unexplored areas within the Minto claim package, management expects to increase the life of mine to over 15 years, subject to successful results of such drilling and applicable mine planning.
The Technical Report includes an economic model that has been developed by JDS using the following key assumptions:
– Long term copper price of US$3.10/lb; gold price of US$1,550/oz and silver price of US$18.50/oz
– Agreed upon terms for new amendment of streaming agreement with Wheaton Precious Metals Corp for gold produced by Minto expected to be signed shortly
– Long term USD to CAD exchange rate of 1.316
– Ore quantities mined and grades for copper, gold and silver as per the latest mine plan developed as part of the Technical Report
– NPV discount rate of 8%
The economic model presented in the Technical Report shows a NPV after Canadian taxes and royalties of US$84 million and average annual EBITDA in excess of US$40 million beween 2021 and 2025 when applying the following price assumptions:
The NPV after Canadian taxes and royalties exhibits strong sensitivity to copper and exchange rates as illustrated in the table below, prepared as part of the Technical Report, to the following:
Project After-Tax NPV8 (CAD$) Sensitivity Based on Fixed Copper Price and FX Rate
(Gold = US$1,550/oz and Silver = 18.50/oz) 4
The Technical Report has been approved by the Joint Advisory Committee of Minto and is only subject to comments from the Canadian Regulatory bodies.
1. Ore reserves and resources based on 31 May 2019 technical report adjusted for production up to 31 March 2021.
2. Metal reserves and resources based on 31 May 2019 technical report adjusted for production up to 31 March 2021.
3. Based on USD CAD exchange rate of 1.316
