We are forecasting production to increase by up to 22% to 85 to 95 million pounds of copper in 2021 with higher grades and increased recovery and throughput post commissioning of the 45,000 tonnes per day mill expansion in the third quarter of 2021. Further, we are maintaining a low cost profile in 2021 with all-in cost expected to be between US$1.80 to $2.00 per pound, which is in line with 2020 expectations."

Mr. Clausen added, "We are continuing to build up a healthy cash position while investing in our low risk, high return growth projects at the Copper Mountain Mine. Following the completion of the mill expansion to 45,000 tonnes per day this year, we will focus on a further mill expansion to 65,000 tonnes per day."

2021 Guidance

Production
Based on the updated life of mine production plan announced on November 30, 2020, the Company expects 2021 production to be 85 to 95 million pounds of copper as a result of higher grades and improved recoveries.

Copper Mountain Mine's 45,000 tonnes per day mill expansion project is expected to be complete with commissioning of the third ball mill by the end of the third quarter of 2021. The 45,000 tonnes per day mill expansion will increase throughput and improve copper recovery, resulting in higher production.

Gold production is expected to be 25,000 to 35,000 ounces and silver production is expected to be 500,000 to 550,000 ounces in 2021.

Costs

The Company expects all-in cost (AIC) to remain low in 2021, estimating AIC to be between US$1.80 to US$2.00 per pound as a result of higher production and improved grade. All Dollars are in US Dollars and assume a CAD to USD exchange rate of 1.33 to 1.

AIC includes sustaining capital, lease payments and applicable administration, in addition to deferred stripping and low-grade stockpile inventory expense. Sustaining capital in 2021 is expected to be approximately US$9 million and deferred stripping is expected to be approximately US$7 million.

Total growth or expansionary capital in 2021 is expected to be approximately US$33 million. The majority of the capital to be spent in 2021 is for the installation of the third ball mill for the 45,000 tonnes per day mill expansion project at the Copper Mountain Mine.
