ASX-Listed Diamond Stocks

COVID-19 disruptions brought broad declines across the diamond-mining sector in 2020, but some companies are still making headway. Learn about six of them here.

ASX-listed diamond stocks have faced headwinds recently. In 2020, COVID-19 disruptions brought broad declines across the sector as many buyers chose not to make luxury purchases.

Although assets like gold, uranium and bitcoin rebounded fairly quickly, the diamond industry wasn’t able to pick back up until well into the second quarter of 2020.

Then, when coronavirus-related trends began to improve later in the year, Australia’s diamond industry was impacted by the closure of the renowned Argyle mine in Kimberley.


The world-class asset was responsible for approximately 90 percent of the world’s fancy pink diamonds. Argyle also contributed 12 million carats of white stones to the global market annually.

“In 2020, pandemic-related production suspensions and curtailments across the industry accelerated this decreasing supply trend,” said diamond analyst Paul Zimnisky.

“More specifically, in 2020 I estimate that global diamond production volume decreased by over 20 percent, to about 113 million carats. This is the lowest output since the 1990s.”

With the Argyle mine out of commission, the Australian diamond sector is in transition, awaiting a restart at the Merlin mine and continued exploration in the Kimberley region. Of the three diamond mines in the country, Ellendale is the only one currently operating.

Despite the slowdown in the industry, upside remains, and ASX-listed diamond stocks continue to move forward at their assets, both in Australia and around the world.

With that landscape in mind, the Investing News Network has used TradingView’s stock screener to put together a list of ASX-listed diamond stocks with projects in Australia, Canada and parts of Africa. Companies are listed in order of market cap size, and all had market caps above AU$10 million as of March 24, 2021. Read on to learn more about them.

1. Rio Tinto (ASX:RIO)

Market cap: AU$40.72 billion; current share price: AU$109.70

Diversified major Rio Tinto is the owner of the famed Argyle mine, which permanently closed in November 2020. The company also has a controlling 60 percent stake in the Diavik diamond mine, located in Canada’s Northwest Territories.

2020 saw output decrease on both continents, as noted in Rio Tinto’s latest annual report.

“Diamond production was 14 percent lower than 2019, attributable to lower carats recovered at Diavik, where a 10 percent reduction in grade was partially offset by an increase in tonnes processed, and the closure of Argyle, as planned, on 3 November,” it reads.

Values were also lower — according to Rio Tinto, its realised diamond price last year was down 21 percent on a weighted average basis.

2. Burgundy Diamond Mines (ASX:BDM)

Market cap: AU$93.46 million; current share price: AU$0.36

Multinational diamond explorer Burgundy Diamond Mines is currently advancing its portfolio of projects in Botswana. The company also has an option agreement for the Naujaat project in Canada, which is operated by North Arrow Minerals (TSXV:NAR).

In addition to gem exploration, Burgundy also holds a stake in a Peruvian gold and silver project.

Shares of the firm are up by triple digits since January, with most of its gains occurring since late February. Most recently, Burgundy’s share price spiked 24 percent over a five day period following the release of the company’s half-year financial report.

3. Jindalee Resources (ASX:JRL)

Market cap: AU$84.65 million; current share price: AU$1.65

Diversified explorer Jindalee Resources has a variety of exploration projects. Most notable is the Aries project, located in the Central Kimberley region roughly three hours east of Derby.

Aside from Aries, Jindalee is advancing several Australian iron ore, gold, nickel and lithium deposits.

Since January, shares of the explorer have steadily trended higher, peaking at AU$2.09 on February 4. Jindalee subsequently fell back to the AU$1.50 range. In mid-March, news that the company had raised AU$9 million to advance its McDermitt lithium project pushed its share value to the current level.

4. Lucapa Diamond (ASX:LOM)

Market cap: AU$53.32 million; current share price: AU$0.06

Africa-focused Lucapa Diamond has had a stellar start to the year, recovering three 100+ carat diamonds since January. It also found a massive 215 carat stone in February.

The first quarter of 2021 has also seen Lucapa sell AU$7.7 million worth of gems recovered from its Mothae mine in Lesotho.

“As with the first sale of Mothae diamonds in 2021, prices achieved by SML at this sale continued to reflect the positive industry mood, and with sales from both operations in 2021 already totalling AU$15 million, it has been a solid start to the year,” said Managing Director Stephan Wetherall. Shares of Lucapa rallied 32 percent a few days later, but have since retreated.

Along with its successes, there have been some challenges for the firm. In January, the Mothae mine was temporarily shuttered as part of a nationwide COVID-19 lockdown.

5. Gibb River Diamonds (ASX:GIB)

Market cap: AU$17.98 million; current share price: AU$0.09

Gibb River Diamonds owns the Ellendale mine, one of Australia’s three diamond mines.

Located in Kimberley, Ellendale is a past producer and is known for its rare yellow stones. Roughly 1.3 million carats have been produced from Ellendale, and it is estimated that 50 percent of the world’s annual yellow diamond supply was once derived from the asset.

Gibb River acquired the project, as well as the mining and exploration leases for the area, in 2019. The company is in the process of raising capital to commence operations at Ellendale. In the meantime, Gibb River is advancing its Edjudina gold project in Western Australia.

The company’s current share value marks a year-to-date high.

6. Astro Resources (ASX:ARO)

Market cap: AU$13.98 million; current share price: AU$0.004

Astro Resources is an exploration company with projects in Australia and the US. The company’s Lower Smoke Creek diamond project is less than an hour away from Rio Tinto’s Argyle mine.

In a financial report, Astro states that it is actively exploring the Lower Smoke asset.

“The company is currently conducting exploration upon tenements considered prospective for diamonds,” the document reads. “No income has been derived from the recovery of diamonds in the period ending 31 December 2020.”

Astro also has a heavy metals project also in Australia and a gold project in Nevada.

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.

Which ASX technology stocks performed the best in 2021? Here’s a look at the five top ASX technology stocks by share price performance.

Australia is home to a thriving tech sector with fresh investment opportunities emerging across a variety of subsectors, such as gaming, fintech, healthcare and cleantech.

The technology sector currently contributes about AU$167 billion to the Australian economy, according to research commissioned by the Technology Council of Australia. This figure has increased by 79 percent from 2016, representing a growth rate that is more than four times that of most industries. In fact, the tech sector is the third largest economic sector in Australia, behind mining and finance/insurance.

Unsurprisingly, many tech stocks on the ASX have performed well in this landscape.


Below the Investing News Network profiles the five best ASX technology stocks in terms of share price performance in 2021. Data for the companies was gathered on December 31, 2021, using TradingView’s stock screener, and all of the best ASX technology stocks listed had market caps above AU$10 million at that time.

1. Novonix

Market cap: AU$4.45 billion; year-to-date gain: 659.5 percent

The first of the best ASX tech stocks on this list is battery technology company Novonix (ASX:NVX), which specializes in developing battery testing equipment for the worldwide lithium-ion battery market. The company was spun out from Dr. Jeff Dahn’s lab at Dalhousie University; Dr. Dahn is one of the pioneers of the lithium-ion battery.

While not yet a revenue generator, the company has benefited from the explosive growth expected out of the fast-moving global electric vehicle (EV) industry.

In December, Novonix announced preliminary results from an environmental impact study; they show the company’s synthetic graphite EV and energy storage system (ESS) battery anode product offers an approximate 60 percent decrease in CO2 emissions, potentially making it “2.5 times better for the environment than Chinese synthetic graphite EV and ESS battery anode material,” as per the Market Herald.

2. Oneview Healthcare

Market cap: AU$114.57 million; year-to-date gain: 488.89 percent

Oneview has signed a number of contracts for the use of this platform, including with Omaha’s Children’s Hospital and Medical Center, Northern Health in Melbourne and Kingman Regional Medical Center in Arizona. In late November, Oneview raised AU$20 million in a private placement with plans to use the funds to further product development, scale its cloud enterprise and strengthen its balance sheet.

In November, the company inked a landmark deal with 2K Games, a label of Take-Two Interactive Software (NASDAQ:TTWO).

In the last weeks of 2021, PlaySide signed a number of deals, including a contract with Shiba Inu Games and a partnership with One True King to co-develop a PC-based game, which will also provide access to One True King's 21 million global followers.

In November, Universal Biosensors signed a three year master collaboration agreement with Mayo Clinic Biopharma Diagnostics. The deal includes work on Universal Biosensors’ Tn antigen cancer biosensor. In late December, the company entered into a global exclusive license agreement with IQ Science for the commercialization of a SARS-CoV-2 N-protein detection test that will use Universal Biosensors' proprietary electrochemical strip and device technology.

Looking for the best-performing cobalt stocks on the ASX? Here's a look at the three top gainers of 2021.

Cobalt prices have soared this past year, with investors paying more attention to this battery metal.

A large reason for cobalt’s bullish behaviour is that it is used to manufacture lithium-ion batteries, which power electric vehicles (EVs) — as demand for EVs continues to rise, it's likely cobalt demand will remain strong too.

Currently the future of EVs looks bright — the market is growing quickly and is expected to boom over the next decade. In the first half of 2021 alone, EV sales ballooned by 160 percent, and by the end of the year, a total of 15 countries had announced measures to begin transitioning toward an all-electric future.


The three top cobalt-producing countries worldwide are the Democratic Republic of Congo, Russia and Australia — the last of which is investing in ramping up its production of the metal.

With that in mind, which Australian cobalt miners gained the most value in 2021? Read on to learn more about the three best cobalt companies on the ASX by year-to-date share price gains. All information was obtained on December 30, 2021, using TradingView's stock screener.

1. Jervois Global

Year-to-date gain: 63.89 percent; current share price: AU$0.59

Jervois Global (ASX:JRV) is best known for its Finland operations, which produce cobalt for chemical, catalyst, pigment, powder metallurgy and — most significantly — battery applications. The company is currently in the process of launching its new Idaho Cobalt Operations (ICO) and is on track to become the first US cobalt miner.

On December 15, Jervois announced an update on ICO, saying first ore is expected in August 2022, with sustainable production expected by December 2022. The estimated capital expenditure required to stay on schedule has risen to US$99.1 million, up from US$92.6 million, with mine engineering 64 percent complete.

2. Cobalt Blue Holdings

Year-to-date gain: 177.78 percent; current share price: AU$0.50

Cobalt Blue Holdings (ASX:COB) is a rare cobalt-only company, and defines itself by its planned ethical and sustainable extraction and production processes. The firm's flagship New South Wales-based Broken Hill project is slated to produce an average of 3,500 to 3,600 tonnes per year of cobalt once in operation.

In December 2021, Cobalt Blue Holdings announced it has executed a memorandum of understanding with the State of Queensland, acting through the Department of Resources, to assess opportunities for the recovery of cobalt (as well as any coexisting base and precious metals) from mine waste.

3. Australian Mines

Year-to-date gain: 31.25 percent; current share price: AU$0.21

Australian Mines (ASX:AUZ) is aiming to supply metals to the growing EV industry, with a focus on ethical and sustainable production. Its flagship Queensland-based Sconi nickel-cobalt project boasts a mine life of over 30 years and will be capable of processing 2 million tonnes of ore annually.

In late October, Australian Mines reported on its quarterly activities, including an agreement for Korea-based LG Energy Solution, a top global producer of EV batteries, to buy 100 percent of the Sconi project’s nickel-cobalt hydroxide output over an initial six year term. The future agreement indicates that LG Energy Solution will buy a projected 7,000 tonnes of cobalt from Australian Mines over the six year period.
