10 ASX Cleantech Stocks

What are the cleantech stocks listed on the ASX? Here’s a deeper look at the burgeoning cleantech industry in Australia.

Clean technology covers a number of industry sectors, such as low-emission technologies, renewable energy, water and wastewater technologies as well as waste and resource efficiencies.

In the first half of 2021, the global cleantech space performed well, almost above expectations.

“There is a clear shift in the industry that is prioritising investments into the space,” Yuan-sheng Yu of Lux Research told the Investing News Network. “Whether that is purely through the installation of renewable energy capacity or in early stage technologies.”


Australia’s cleantech arena is also performing with strength, according to the Deloitte Australia CleanTech Index, which offers a quarterly review of cleantech stocks listed on the ASX.

“The companies included in the Index range across renewable energy, energy efficiency, resource efficiency, energy storage, battery minerals and water treatment,” states Renew Economy. “These are the industries that are redefining how cities work and how our communities live, so it is likely we will see them continue to play a critical role in our economy’s post-Covid recovery.”

With the positive outlook for cleantech in mind, here’s a look at 10 ASX cleantech stocks that are tracked by the Deloitte Australia CleanTech Index. Companies are listed in order of largest to smallest by market cap, and all numbers and figures were current as of July 30, 2021.

Winsome Resources CEO Chris Evans

Winsome Resources CEO Chris Evans said, “Canada and the US are working feverishly to develop an internal battery materials supply chain and we think we're going to play a critical role in that.”

Winsome Resources CEO Chris Evans: Sustainable Hardrock Lithium Opportunities in Quebec youtu.be


Winsome Resources (ASX:WR1) CEO Chris Evans joined the Investing News Network to discuss the company and its Cancet lithium project in Quebec, Canada.

"We listed on the ASX on November 30, 2021," he explained. "We're lithium focused but based in Canada, and we've been pretty successful in the last six months — our share price has done well. I think I've been putting this down to the success factors which we possess as a company, including the fact that we're into lithium at a moment with high demand. Any mining company that's associated with lithium has tended to do well.

“Our assets are in Quebec, a fantastic mining jurisdiction for all sorts of reasons. Also, being listed on the ASX — Australian investors tend to like early stage plays a bit better. They've certainly woken up to the electric vehicle and lithium revolution that's occurring in the world. And it's a pleasure having the assets in Canada.”


Next, Evans got into specifics about the company's flagship project. “The Cancet project is our flagship, in the James Bay region of Quebec. All our projects are hard-rock lithium; that's digging the rocks out of the ground and concentrating the lithium in them. Then it gets converted into the final product, which is lithium carbonate or hydroxide, that then goes into electric vehicle batteries,” he explained.

“Cancet’s had about 5,500 metres of drilling done on it historically, so we know that there's a great deposit of lithium at fantastic grades. It outcrops on the surface, the lithium-containing spodumene from the pegmatite rock, where we have 3.7 percent lithium oxide over a 17 metre interval from the surface at our most successful drill hole. We just completed 2,000 metres of drilling ourselves, increasing our knowledge of the orebody that's there, and also looking for extensions to the orebody. We've got 395 claims, and our drilling and exploration is only over about 15 of the claims. So we've got a lot further to look here and a lot more to develop.”

As for supply location, and the company's relationship with the international market, Evans said, “We think it's fantastic for us, and our shareholders, that we have assets in Quebec. Roughly 50 percent of the world's hard-rock lithium comes from Australia, where it’s mined and concentrated. The problem is that final conversion into lithium carbonate or hydroxide all occurs at the moment in China ... lithium is on the critical minerals list in Canada, the US and Australia, and Canada and the US are working feverishly to develop an internal battery materials supply chain. We think we're going to play a critical role in that.”

Elaborating on the sustainability industry that drives the battery revolution, he said, “(Nearly) all power in Quebec is generated by hydroelectricity and renewable forms of electricity. That’s very important, because the mining and concentration process for lithium products traditionally produces a large carbon footprint, because it's energy intensive. The EU, from 2024, has mandated that all batteries are labeled with the carbon footprint of all the materials that are contained within them. Then, by about 2026, there's specific targets that batteries have to meet in order to be sold in the EU. If you don't have a renewable source of energy to produce your lithium products that go into those batteries, it's going to severely restrict your markets — and that's another bonus for us being in Quebec.”

Evans said that Winsome Resources’ approach is to develop a mine itself, rather than selling or partnering. “We will approach this as if we are going to be developing the Cancet project, and producing lithium ourselves, in four or so years. And I think that'll best serve our shareholders.” With regards to other ways the company could benefit investors, Evans said, “Being listed on the ASX, and having access to a lot of capital, I think there's a great opportunity for us to acquire other projects in Canada. We're about to start our summer exploration. And we're on the lookout for a new project. So I think the good news is really to come.”

Where are the silver mines in Australia? You might be surprised to learn that the country is home to one of the world’s top primary silver producers.

Mining is a big part of Australia’s history, and it continues to shape the country’s economy and position in the world today. The nation is one of the world’s top producers and exporters of resources, with coal, uranium, copper and gold being some of its best-known commodities.

Australia is also a key producer of silver — it was the world’s fifth-largest producer of the metal in 2021, tied with Russia, putting out 1,300 MT. Interestingly, most of Australia's silver is produced from silver-bearing galena, but some is also produced from copper and gold mining.

Refined silver comes mainly from the Port Pirie lead smelter and refinery in South Australia, though silver is also refined at gold refineries in Perth, Kalgoorlie and Melbourne.


But where are the silver mines in Australia, exactly? While it’s interesting to know what types of deposits the precious metal is found in, many investors want to know what companies are producing silver and where their mines are located geographically. Read on to find the answers to those questions.

Where are the silver mines in Australia?

Silver has played a role in Australia since the mid-1800s — Wheal Gawler, Australia’s first metal mine, was a silver-lead mine developed in South Australia in the 1840s. And that’s not Australia’s only early silver-mining operation — the Broken Hill deposit in New South Wales and the Mount Isa deposit in Queensland are two other early Australian silver discoveries.

Broken Hill, a lead-zinc-silver deposit, was discovered in 1883 by German immigrant Charles Rasp, and the Broken Hill Proprietary Company was born in 1885; it ultimately merged in 2001 with another mining giant, Billiton, to form BHP Billiton (ASX:BHP,NYSE:BHP,LSE:BLT). BHP Billiton is no longer involved with Broken Hill, but ore is still being extracted there today. Perilya now runs the southern and northern operations.

For its part, Mount Isa was discovered in 1923 by John Campbell Miles, and like Broken Hill is still producing today. It was acquired by Glencore (LSE:GLEN) in 2013 and in addition to silver is also a producer of zinc.

These major early Australian silver discoveries are not the country’s only sources of silver. Other silver mines in Australia include Cannington, one of the world’s top primary silver producers. It’s a fly-in, fly-out mining and processing operation that is owned by South32 (ASX:S32,LSE:S32), a diversified resource company spun out from BHP Billiton in 2015. Cannington also produces lead and zinc.

Australia holds the McArthur River mine as well, which opened in 1995 and is owned by Glencore subsidiary McArthur River Mining. The mine is one of the world’s largest zinc-lead-silver mines, and is located in Australia’s Northern Territory.

Glencore’s 2021 annual report claims total silver production reached 31.519 million ounces for the year, representing a 4 percent drop from 2020. That includes 625,000 ounces from McArthur River.

The Century mine, which previously belonged to MMG (HKEX:1208), shut its doors at the end of 2015, but was a major producer of zinc (and silver) until that time. It was reopened in mid-2018 by New Century Resources (ASX:NCZ) and the company says it now has an estimated annual production capacity of 264,000 tonnes of zinc and 3 million ounces of silver.

Independence Group (ASX:IGO) also produces silver, along with copper and zinc, at its Jaguar operation in Western Australia. Gold producer Silver Lake Resources (ASX:SLR) owns some projects with silver reserves as well. As you can see, there are and have been many silver mines in Australia.

Future silver mines in Australia?

In addition to being home to a slew of large silver mines, Australia also plays host to many companies that are exploring and developing silver projects. Below are a few that have made recent progress.

Please let us know in the comments if we’ve forgotten to mention any Australia-focused silver companies. All companies listed had market caps of at least AU$5 million on May 19, 2022.

Argent Minerals (ASX:ARD) — Argent Minerals’ main asset is its 100-percent-owned Kempfield polymetallic project in New South Wales. In May 2018, the company announced an updated resource estimate for the asset — its silver equivalent contained metal now stands at an estimated 100 million silver equivalent ounces at 120 g/t silver equivalent; that’s approximately double the previous estimate.

In total the company has three projects, with all of them being in New South Wales.

Investigator Resources (ASX:IVR) — Investigator Resources is advancing silver, copper and gold deposits in South Australia. Currently its properties include the Peterlumbo/Paris silver project, the Eyre Peninsula and Stuart Shelf projects and the Northern Yorke Peninsula projects.

The total resource for Paris stands at an estimated 18.8 million tonnes at 88 g/t silver and 0.52 percent lead for 53.1 million ounces of contained silver and 97,600 tonnes of contained lead (at a cut off of 30 g/t silver). The indicated component is 12.7 million tonnes of silver (95 g/t) and represents 73 percent of the total estimated resource ounces.

Horizon Minerals (ASX:HRZ) — Horizon Minerals owns the Nimbus silver-zinc project in Western Australia. Nimbus has a high-grade silver-zinc resource estimate of 255,898 tonnes at 773 g/t silver and 13 percent zinc; the total Nimbus resource stands at 1.21 million tonnes at 52 g/t silver, 0.9 percent zinc and 0.2 g/t gold.

Silver Mines (ASX:SVL) bills itself as a leading Australian silver exploration company, and has spent a considerable amount of time acquiring Australian silver projects. Those include Malachite Resources’ (ASX:MAR) Conrad project and Kingsgate Consolidated’s (ASX:KCN) Bowdens silver project.

While the company’s main focus has been on the Webbs silver project in New South Wales, the Bowdens project represents the largest undeveloped silver project in Australia, and Silver Mines is working to get the project through the feasibility, environmental impact statement and permitting stages.

In a 2018 report, the feasibility study demonstrated an average silver production of 3.4 million tonnes per annum for the project, with 5.4 million during the first three years of operation. Estimations also included 6,900 tonnes of zinc and 5,100 tonnes of lead.
