Rio Tinto and Comptech are partnering to bring a new generation of aluminium alloys to the market for use in advanced technologies such as electric vehicles and 5G antennas.

Rio Tinto’s metallurgical experts have designed the alloys for the semi-solid Rheocasting process offered by Comptech, to meet the requirements of producing large, specialised single piece designs, known as giga-casting.

The alloys offer high strength, electrical and thermal conductivity properties, while Rheocasting allows fast, low cost production of advanced lightweight designs. The products are currently undergoing qualification with automakers in Europe.

Rio Tinto vice president Sales and Marketing Aluminium Tolga Egrilmezer said: “Through this partnership, we are delivering a new range of specialised alloys designed to deliver high performance, lower cost solutions for advanced applications like electric vehicles and 5G antennas. This is an area of emerging demand where our industry leading research and development capability allows us to deliver products that meet the specific needs of manufacturers and end customers.”

Comptech Group CEO and owner Per Jansson said: “We are in the capacity ramp up for the next generation of advanced technologies across sectors such as automotive and communications, and our customers, both foundries and OEM´s will need the development of more advanced parts. This partnership positions us to offer customers the combined advantages of our casting process expertise and Rio Tinto’s technical strength and preferred alloys suite.”

Notes to editors

Rheocasting is an emerging semi solid casting process that allows the production of low-cost aluminium components with high strength, extremely low porosity and a broad range of possible alloys. Comptech has seen a breakthrough in uptake of the process over recent years, with orders for high volume deliveries to the automotive industry as well as supplying equipment supported with technical expertise.

The Rheocasting process is ideally suited to giga-castings for electric vehicles, where a single large aluminium part is produced to significantly reduce the number of components, weight and assembly time and cost. It also offers significant advantages in the production of 5G antennas, where a single large aluminium housing can deliver high thermal conductivity and sealing features with reduced manufacturing, installation and maintenance cost.

Rio Tinto is progressing an innovative new technology to deliver low-carbon steel, using sustainable biomass in place of coking coal in the steelmaking process, in a potentially cost-effective option to cut industry carbon emissions.

Over the past decade, Rio Tinto has developed a laboratory-proven process that combines the use of raw, sustainable biomass with microwave technology to convert iron ore to metallic iron during the steelmaking process. The patent-pending process, one of a number of avenues the company is pursuing to try to lower emissions in the steel value chain, is now being further tested in a small-scale pilot plant.

There are many big Australian gold stocks, but these are the five top companies in the sector by market cap.

Australia is the fourth largest producer of gold worldwide, and this past year has brought ups and downs for the commodity. The precious metal hit its 2021 high point early on and fell soon after.

Lately, gold has been resting at a strong price of around US$1,800 per ounce, and it seems like it will exit the year that way. It may even be in for a serious price hike if inflationary pressures continue on their current trajectory.

Read on to learn more about Australia’s five top gold companies by market cap. All market cap and share price information was obtained on November 25, 2021, using TradingView's stock screener.


1. Newcrest Mining

Market cap: AU$19.54 billion; current share price: AU$24.14

Newcrest Mining (ASX:NCM) operates a portfolio of gold mines across Australia, Canada and Papua New Guinea. These include its New South Wales-based Cadia mine and its Western Australia-based Telfer and Havieron mines.

In November 2021, Newcrest agreed to purchase British Columbia-based Pretium Resources (TSX:PVG,NYSE:PVG) for C$3.5 billion, marking the company’s expansion into Western Canada.

2. Kirkland Lake Gold

Market cap: AU$14.57 billion; current share price: AU$54.99

Kirkland Lake Gold (ASX:KLA) has mining operations in Australia and Canada, both of which are low-risk, gold-rich countries. The company’s Fosterville mine is based in Victoria, Australia, and as of December 31, 2018, its mineral reserves stood at 2.7 million ounces. It produced 640,467 ounces in 2020.

In September 2021, Kirkland Lake Gold and Agnico Eagle Mines (TSX:AEM,NYSE:AEM), a Canadian gold miner, announced a “merger of equals." The new company will go by the name Agnico Eagle Mines, and the companies expect the transaction to close in late 2021 or early 2022.

3. AngloGold Ashanti

Market cap: AU$12.43 billion; current share price: AU$5.83

AngloGold Ashanti (ASX:AGG) is a global gold miner formed in 2004. It has two Australia-based operations, both of which are based in Western Australia’s northeastern goldfields: Sunrise Dam and Tropicana. Sunrise Dam is 100 percent owned, while Tropicana is 70 percent owned, with the remaining 30 percent owned by Regis Resources (ASX:RRL,OTC Pink:RGRNF). In 2020, these operations produced 554,000 ounces of gold.

In Q3 2021, AngloGold Ashanti reported total gold production of 613,000 ounces at a total cash cost of US$927 per ounce. This represents a 5 percent quarter-over-quarter increase in production, though a year-to-date decrease.

4. Northern Star Resources

Market cap: AU$11.39 billion; current share price: AU$9.66

Northern Star Resources (ASX:NST) is an Australian gold-mining company with projects throughout Western Australia and North America at its Kalgoorlie, Yandal and Pogo production centres.

In late November 2021, Northern Star announced an agreement to buy Newmont Australia’s power business for US$95 million. The company paid US$25 million for the option to purchase this business, an opportunity it was given through its recent 50 percent acquisition of Kalgoorlie Consolidated Gold Mines.

5. Evolution Mining

Market cap: AU$7.53 billion; current share price: AU$4.12

Australian gold miner Evolution Mining (ASX:EVN) has projects throughout New South Wales, Queensland and Western Australia, as well as in Ontario, Canada. Evolution Mining produced 680,788 ounces of gold in the 2021 fiscal year at an all-in sustaining cost of AU$1,215 per ounce.

In 2019, Evolution Mining became one of only two Australian gold companies to be included in the Dow Jones Sustainability Index (INDEXDJX:W1SGI). In 2020 and 2021, the company made several strategic acquisitions and divestments, including its high-value purchases of the Red Lake and the Kundana operations.

What are the largest Australian copper companies? These five ASX copper stocks are the biggest on the exchange by market cap.

Last year, pandemic restrictions forced copper mines to shut down across the world, driving down global production and causing the 10 largest copper-mining companies to suffer dramatic losses.

But in 2021, copper hit an all-time high of US$10,700 per tonne, and stayed over US$9,000 for much of the year.

The three top copper-producing countries globally are Chile, Peru and China, with Australia coming in at number six. Still, there are plenty of untapped resources in the land down under, and Australia is making a name for itself as an up-and-coming producer of this important base metal.


Read on to learn more about the top five Australian copper companies on the ASX, ranked by market cap. All market cap and share price information was obtained on November 26, 2021, from TradingView.

1. BHP

Market cap: AU$192.56 billion; current share price: AU$38.03

BHP (ASX:BHP) is a top global producer of copper, nickel, potash, iron ore and metallurgical coal, with copper production centralised at its South Australia-based Olympic Dam mine.

The company, whose headquarters are in Melbourne, Australia, emphasises copper’s function in renewable energy systems and the metal’s critical role in reducing carbon dioxide emissions.

Recently, BHP has focused its attention on its energy assets. In late November, the company merged its oil and gas portfolio with Woodside Petroleum, a deal that was originally struck in August of the same year. On the mineral side of its operations, BHP was looking to acquire Noront Resources (TSXV:NOT,OTC Pink:NOSOF), a Canada-based nickel, copper, chrome and platinum company, but decided not to match a superior offer.

2. OZ Minerals 

Market cap: AU$8.77 billion; current share price: AU$25.70

OZ Minerals (ASX:OZL) is a South Australia-based copper-mining company founded in 2008. Its operations include the Carrapateena project, where construction was completed in 2019, and the upcoming Malu underground mine, which was commissioned in 2015.

In a November press release, OZ Minerals reported a year-to-date 5 percent increase in group ore reserve copper metal tonnes. In its third quarter results, the company reported guidance of between 120,000 and 145,000 tonnes of copper for the year.

3. Sandfire Resources

Market cap: AU$2.59 billion; current share price: AU$6.11

Sandfire Resources (ASX:SFR) owns 7,189 square kilometres in the Bryah Basin region of Western Australia, including its DeGrussa and Monty operations. Both of these are 100 percent owned and produce copper and gold.

The company released its third quarter results in October, reporting total copper production of 15,946 tonnes. Sandfire expects output of between 64,000 and 68,000 tonnes of copper in 2022.

4. 29Metals

Market cap: AU$1.29 billion; current share price: AU$2.63

Australia-based mining company 29Metals (ASX:29M) has the Golden Grove mine in Western Australia and the Capricorn copper mine in Queensland, along with several promising new growth opportunities lined up. 29Metals focuses on copper production, though it also mines for zinc, gold and silver.

According to an October release from the company, production was weaker than expected at Golden Grove during the September quarter. However, the asset's quarter-on-quarter decline of about 10 percent was largely offset by a strong performance at Capricorn.

5. Copper Mountain Mining

Market cap: AU$804.96 million; current share price: AU$3.81

Copper Mountain Mining (ASX:C6C) is a Canadian and Australian copper miner, with its flagship Copper Mountain operation in British Columbia, Canada, and its Eva and Cameron copper projects in Queensland, Australia.

In the third quarter, Copper Mountain Mining reported total output of 22.4 million pounds of copper at its Copper Mountain mine, representing a 12.1 percent quarter-over-quarter decline in production. The company still reported positive cash flow, with strong construction and exploration gains made at its Eva and Cameron projects.
