(Kitco News) – The grade or concentration of a mineral or metal in ore directly affects costs associated with mining as well as its subsequent beneficiation and extraction of precious components.
Kitco ranked the top ten currently active gold operations in the world based on gold grade in a tonne of processed ore reported for Q1 2021. Kitco looked at operations that are separate reporting units and which have gold grade figures disclosed by the owners/operators.
Two Kirkland Lake Gold’s mines tied for the first place in the list of the richest gold mines globally with identical gold grades reported for Q1 2021.
At its Fosterville mine in Australia, the company reported that a gold grade of 19.8 g/t in Q1 2021 was significantly lower than 42.4 g/t in Q1 2020, which is consistent with the company’s previously stated plan to reduce production in the Swan Zone by increasing mining activities in other, lower-grade, areas of the mine, with the intention of creating a more sustainable operation over a longer period while the company continues its extensive exploration program.
Another Kirkland Lake Gold’s Macassa mine, located in Ontario, Canada, reported an identical gold grade of 19.8 g/t in Q1 2021, which was slightly higher than 19.7 g/t gold grade reported in Q1 2020.
Alamos Gold’ Island Gold mine is a high grade, low-cost underground mining operation located just east of the town of Dubreuilville, Ontario, Canada, 83km northeast of Wawa. Underground grades processed averaged 13.03 g/t Au in the first quarter, an 11% increase over Q1 2020 and above the Mineral Reserve grade.
Gran Colombia Gold’s Segovia operations, an area of approximately 9,000 hectares, is made up of several mines including El Silencio, Sandra K, Providencia, and Carla, located in the Segovia-Remedios mining district of Antioquia, Colombia. In Q1 2021, the company reported 12.83 g/t gold, which is less than 14.9 g/t a year ago.
Wesdome Gold’s Eagle River mine in Canada sits fifth with 12.8 g/t gold grade reported in Q1 2021, which is below budget and 9% lower compared to Q1 2020 due to stope sequencing.
