1. Boddington

Newmont (TSX:NGT,NYSE:NEM) became the sole owner of this open-pit gold and copper mine in 2009. The asset is located 16 kilometres from Boddington, Western Australia.

Iin calendar year 2023, Boddington produced 745,000 ounces of gold, a 7 percent drop from the 798,000 produced in 2022.

Newmont expects production at Boddington to decline significantly in 2024, setting guidance at only 575,000 ounces, which it attributes to lower-grade ore. However, the company expects production to increase in 2026 as it works to complete laybacks in the north and south pits.

The mine produced 147,000 ounces of gold in the second quarter of 2024.

2. Cadia Valley

Located in New South Wales, Cadia Valley is now owned and operated by Newmont following its acquisition of Newcrest Mining in November 2023. The mine is made up of the Cadia East underground panel cave mine and the Ridgeway underground mine (currently on care and maintenance), which produce gold doré bars from a gravity circuit and gold-rich copper concentrates from a flotation circuit.

Once the biggest gold mine in Australia, Cadia’s production numbers have been in decline in recent years, slipping from 843,000 in 2020 to 597,000 ounces in fiscal 2023. Output declines in 2023 were due to planned shutdowns as the company worked on development activities for the PC1-2 project and began cave ramp-up on PC2-3.

Newmont is forecasting further declines in production from Cadia in 2024. It set guidance at 370,000 ounces as it continues on underground development on block caves and tailings expansion and plans for the next decade of mine life.

Cadia produced 117,000 ounces of gold in the June quarter of 2024.

3. KCGM

Northern Star Resources (ASX:NST,OTC Pink:NESRF) owns Kalgoorlie Consolidated Gold Mines (KCGM), which includes the Fimiston open pit — also known as the Super Pit — the Mount Charlotte underground mine and the Fimiston and Gidji processing plants. The operations reached the milestone of 50 million ounces of gold production in 2019.

KCGM is located in the legendary Golden Mile, which was once reputed to be the richest square mile on Earth. In its fiscal 2024, KCGM produced 449,032 ounces of gold, and the operations sit on 13.3 million ounces of reserves.

In mid-2023, Northern Star launched a AU$1.5 billion expansion project at KCGM that is expected to increase production to 900,000 ounces per year by 2029. As the expansion enters its second year, the company reported major works would include the installation of grinding, crushing and flotation cells along with site infrastructure.

KGCM produced 116,690 ounces of gold during the second quarter of 2024.

4. Tropicana

Tropicana is co-owned by AngloGold Ashanti (ASX:AGG,NYSE:AU,OTC Pink:AULGF), which owns 70 percent, and Regis Resources (ASX:RRL,OTC Pink:RGRNF), which owns the remaining 30 percent.

The mine spans 3,600 square kilometres and stretches over close to 160 kilometres in strike length along the Yilgarn Craton and Fraser Range mobile belt collision zone. The regional geology is dominated by granitoid rocks, making it a rare example of a large gold deposit within high-grade metamorphic rocks that have undergone widespread recrystallisation and melting.

In calendar 2023, Tropicana produced 442,887 ounces of gold, with AngloGold Ashanti’s 70 percent accounting for 310,000 ounces and the rest attributed to Regis.

As part of AngloGold Ashanti's commitment to lowering its carbon footprint, a 62 megawatt wind and solar facility is currently under construction at Tropicana. The project is expected to be completed during the first quarter of 2025 and will reduce greenhouse gas emissions at the site by an estimated 65,000 per year.

Tropicana produced 102,763 ounces of gold during the second quarter of 2024.

5. Tanami

Tanami has been fully owned and operated by Newmont since 2002 and is located in the Northern Territory's remote Tanami Desert. Both the mine and the plant are located on Aboriginal freehold land that is owned by the Warlpiri people and managed on their behalf by the Central Desert Aboriginal Lands Trust.

Tanami is a fly-in, fly-out operation in one of Australia’s most remote locations. The asset is 270 kilometres away from its closest neighbours, the remote Aboriginal community of Yuendumu.

In 2023, Tanami produced 448,000 ounces, 7 percent lower than the 484,000 ounces from the previous year. Newmont has projected that 2024 will see a further decrease to 400,000 ounces, attributing the reduced output to lower grades from deeper in the underground mine as it continues to develop the expansion.

In October 2023, Newmont announced the Tanami Expansion 2 project, which has an expected commercial production date of late 2025. Once complete, it is expected to extend the mine's life beyond 2040 and increase its annual gold production by approximately 150,000 to 200,000 ounces for the initial five years.

Tanami produced 99,000 ounces of gold in the June quarter of 2024.

6. Cowal

Owned by Evolution Mining, Cowal is the company's largest gold-producing asset. The mine is located near Bland Shire in New South Wales within the traditional lands of the Wiradjuri people.

In 2023, Evolution marked important milestones in the mine’s development with the ramp-up in production of its newly cutback Stage H portion of its open pit mine and the early completion of its underground mine.

The new underground portion of Cowal helped to deliver a record production in its fiscal year 2024 of 312,644 ounces of gold versus 276,314 ounces during its fiscal 2023.

Due to high gold prices and strong production numbers, the company reported that it has been able to repay capital costs for the acquisition and expansion at Cowal. In total, the mine generated AU$604.9 million in fiscal 2024.

Cowal produced 94,826 ounces of gold in the quarter ending June 30.

7. Jundee

Jundee is located in the Northern Goldfields region of Western Australia and is owned by Northern Star after the miner purchased it from Newmont in 2014 for AU$82.5 million. The property is well known due to the fact that it solely uses underground mining. Along with Cadia Valley, Jundee is one of the lowest-cost gold producers on this list.

The asset produced 280,963 ounces of gold in the company’s fiscal 2024, lower than the 320,201 ounces produced the previous year. Production at Jundee was impacted by a fire in the processing plant in Q4 that resulted in 10 days of unplanned downtime.

In June of 2023, Northern Star announced it would be integrating 24 megawatts (MW) of wind and 16.9 MW of solar into its existing gas power station network and would be supplementing the entire system with 12 MW of battery energy storage. Once complete renewable generation is expected to account for 56 percent of the mine's power and will contribute to a 36 percent reduction in Northern Star’s carbon footprint.

In its 2024 report released in August, the company reported that three of the four planned wind turbines have been installed, with the fourth on track for commissioning later in 2024.

During the second quarter of 2024, Jundee produced 72,661 ounces of gold.
