(Kitco News) - Newcrest’s Cadia was the largest gold mine in Australia in Q1 2021, followed by Newmont’s Boddington and Tanami mines. Six out of the top 10 mines in Australia increased output in Q1 2021.

Kitco ranked the top 10 gold mines in Australia by reported production in Q1 2021.

1. Cadia. 180 koz.
Gold production at Newcrest’s Cadia operations of 180 koz in Q1 2021 was 8% lower than a year before primarily due to a lower mill throughput caused by a scheduled maintenance of Concentrator 1 and the materials handling system.

2. Boddington. 152 koz.
Newmont’s Boddington mine increased production by 7% to 152 koz primarily due to higher ore grade milled as a result of higher ore grade mined and higher mill throughput.

3. Tanami. 117 koz.
Another Newmont’s Tanami mine produced 117 koz of gold in Q1 2021, an increase of 1% primarily due to higher mill throughput and a lower build-up of in-circuit ounces.

4. Kalgoorlie. 111 koz.
Northern Star’s Kalgoorlie Operations produced 5% less gold due to the impact of a one-off planned 14-day mill shut, modernising the mill control systems. This reduced processed ore to 2.8Mt. Recoveries improved to 86%.

5. Fosterville. 109 koz.
Kirkland Lake’s Fosterville mine produced 109 koz in Q1 2021 based on processing 174,206 tonnes at an average grade of 19.8 g/t and average mill recoveries of 98.2%. Q1 2021 production decreased by 32% compared to production of 160 koz in Q1 2020, when the mine processed 118,701 tonnes at an average grade of 42.4 g/t and average recoveries of 98.8%. This decline reflected a lower average grade 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.

6. Telfer. 105 koz.
Gold production of 105 koz at Newcrest’s Telfer operation was 8% higher than a year before, driven by higher throughput and recovery, partially offset by lower head grade and a reduction in dump leach ounces.

7. St. Ives. 94 koz.
Gold production at Gold Fields’ St. Ives mine was 94 koz in Q 2021, a 1% increase over Q1 2020.

8. Tropicana. 82 koz.
Production at AngloGold Ashanti’s Tropicana mine was 82 koz for the first quarter of 2021, a 21% decline compared to 104 koz produced during the same period last year. Production decreased as increases in mill throughput and metallurgical recovery were more than offset by a planned 25% drop in the mill feed grade to 1.26 grams per tonne.

9. Gruyere. 66 koz.
Gold production at another Gold Fields’ Gruyere mine was 66 koz in Q 2021, an 11% increase over Q1 2020.

10. Jundee. 64 koz.
Northern Star produced 64 koz at Jundee in Q1 2021, which is 17% more than a year before. Operating strike development continued across all mining areas at Jundee. Development advance was especially strong in March with a new monthly record for jumbo advance of +2,000m. Stope tonnes increased across the quarter as new operating areas were accessed through increased development advance.
