• Production of 2,134 ounces of gold contained in concentrates; a decrease of 22% over Q1 2020.
• Average processed tonnes per day of 954, an increase of 9% over Q1 2020.
• Copper head grade of 3.23%, a decrease of 2% over Q1 2020.
• Gold head grade of 1.71 grams per tonne; a decrease of 12% over Q1 2020.
• Copper and gold recovery of 92.4% and 56.9%; no significant change for copper and a decrease of 3% for gold over Q1 2020

First Quarter Operational Review

Mined and processed ore was below Company budget for the first quarter caused primarily by the temporary work stoppage as a result of a tailings pipe malfunction and to a lesser extent by a much heavier rainy season this year. The decrease for copper and gold output for the quarter relative to Q1 2020 is mostly explained by 7% decrease in processed ore, while for gold an additional factor was a 12% decrease in head grade. Copper recoveries slightly improved when compared to the same period last year, while gold recoveries during the quarter were in line with Company projections. Gold recovery decrease is due to an increase in the copper content in the concentrate, this increase in the copper content in the concentrate provides a net economic benefit, especially at current copper prices, offsetting the decrease in gold recovery. The Company will continue to explore improving the copper content in the concentrate in the following quarters while increasing the gold recovery.
