What is Gallium and Why is it Important?
Gallium is a soft, silvery metal that has emerged as one of the most critical elements in modern technology. Though relatively unknown to the general public, this rare metal has become fundamental to semiconductor manufacturing, electronics production, and renewable energy technologies, particularly in solar panels and high-efficiency LED lighting.
The global gallium market is witnessing explosive growth potential, with projections showing an increase from US$2.45 billion in 2024 to a staggering US$21.53 billion by 2034. This represents a nearly tenfold expansion in just a decade, highlighting gallium's growing strategic and economic importance.
China currently dominates global gallium production, controlling approximately 80% of the world's supply. This concentration has raised significant geopolitical concerns, especially after China implemented export restrictions on gallium in 2023. These export bans have emphasized gallium's status as a strategic resource and created urgent supply concerns for Western nations.
Industry experts point to gallium's unique properties that make it irreplaceable in certain applications. "Gallium arsenide and gallium nitride compounds are essential for high-frequency, high-power electronic devices that silicon-based semiconductors simply cannot match," notes a leading materials science researcher. These compounds offer superior performance in power electronics, radar systems, and 5G telecommunications infrastructure.
The Technical Importance of Gallium
Gallium's technical significance stems from its remarkable properties. With a melting point of just 29.76°C (85.57°F), it's one of few metals that can be liquid near room temperature, yet it has a high boiling point of 2,400°C, giving it one of the largest liquid ranges of any element.
This versatile metal forms compounds with extraordinary semiconductor properties. Gallium arsenide (GaAs) offers electron mobility about six times faster than silicon, enabling higher frequency operation in electronic devices. Meanwhile, gallium nitride (GaN) has emerged as a revolution in power electronics, enabling smaller, more efficient power converters and chargers.
The renewable energy sector depends heavily on gallium for copper-indium-gallium-selenide (CIGS) solar cells, which offer advantages in flexibility and lower production costs compared to traditional silicon panels. Furthermore, Rio Tinto's Innovative Gallium Breakthrough has demonstrated how even bauxite waste can be transformed into this vital tech resource.
How Did RareX Become the Top ASX Gallium Play in March?
RareX Limited (ASX:REE) made headlines after reporting an unexpected gallium discovery at its Cummins Range project in Western Australia. This revelation propelled the company's stock price to remarkable heights, recording a 171% increase in March 2025 alone.
The discovery has generated exceptional excitement due to the extraordinary grades encountered. The company reported values up to 6,826g/t Ga₂O₃ (gallium oxide), potentially making it one of the highest-grade gallium discoveries not just in Australia, but globally. To put this in context, most economic gallium deposits typically contain less than 100g/t Ga₂O₃.
What makes this discovery particularly significant is its scale. Of the 11,487 assays completed across the project, an impressive 36% contained concentrations greater than 40g/t Ga₂O₃, indicating substantial mineralization throughout the deposit rather than isolated high-grade pockets.
The Significance of the Cummins Range Discovery
RareX's Cummins Range project was already recognized as one of Australia's largest pre-development rare earths and phosphate projects. The addition of substantial gallium resources has the potential to fundamentally transform the economics and strategic importance of the entire project.
The company has initiated a comprehensive re-assaying program of historical samples to fully integrate gallium into its development plans and resource calculations. This represents a substantial shift in the project's focus and potential revenue streams.
Notably, gallium is officially listed as a critical mineral by the European Union, United States, and Australia, highlighting its strategic importance to advanced economies. This designation provides potential pathways to development funding and offtake agreements that might not otherwise be available.
Geological experts have noted that the Cummins Range deposit appears to have formed through unique mineralization processes. "What we're seeing here is exceptional enrichment likely related to specific hydrothermal alteration events that concentrated gallium within the carbonatite complex," explained a senior geologist familiar with the deposit. These developments highlight mining's crucial role in the clean energy transition, as these critical minerals become increasingly vital.
Which Other Resource Stocks Performed Well in March?
While RareX's gallium discovery dominated industry headlines, gold-focused companies represented the majority of top performers during March 2025. This performance coincided with gold's continued bull run in global markets.
Top 3 Stock Gainers in March 2025
- RareX (ASX:REE) – Up 171% (gallium discovery)
- Trek Metals (ASX:TKM) – Up 145% (gold)
- Errawarra Resources (ASX:ERW) – Up 120% (silver and gold)
Gold's Strong Performance
Gold continued its impressive price trajectory in March, breaking through the psychologically important US$3,000/oz barrier and reaching approximately US$3,140/oz. For Australian producers, this translated to over AU$5,000/oz, creating exceptional operating margins for efficient miners.
This price strength was reflected in share performance, with 24 gold stocks featuring among the top 50 performers for the month. Notable performers included Dateline Resources (ASX:DTR), Black Dragon Gold (ASX:BDG), and Gorilla Gold Mines (ASX:GG8), each recording gains exceeding 50%.
Market analysts attribute gold's ongoing strength to persistent geopolitical uncertainties, inflationary concerns, and central bank purchasing programs. "We're seeing sovereign wealth funds and central banks diversifying away from traditional reserve currencies at an unprecedented rate," noted a precious metals strategist at a major investment bank. For those interested in capitalizing on these trends, investing in mining stocks could provide significant opportunities.
What Made Trek Metals Stand Out in March?
Trek Metals (ASX:TKM) emerged as March's second-best performer after announcing the discovery of visible gold at its Christmas Creek project in Western Australia's Kimberley region. This significant find contributed to the company's impressive 145% stock price increase during the month.
Key highlights from Trek's exploration results include:
- Visual identification of gold in drill chips from reverse circulation hole 24XCRC097
- Exceptional high-grade intercepts including 10m at 12.66g/t from 59m depth
- Additional mineralized zone of 10m at 7.34g/t from 94m in the same hole
- Positive metallurgical indications for both geological continuity and processing potential
Exploration geologists have noted that the presence of visible gold is particularly significant. "When you can see gold with the naked eye in drill chips, it typically indicates potential for high recovery rates through conventional processing," explained a senior mining analyst specializing in Australian gold projects.
Trek has announced plans to accelerate drilling at the Martin prospect within the Christmas Creek project, with investors eagerly awaiting follow-up results that could potentially enhance the discovery further.
Why Did Errawarra Resources See Significant Gains?
Errawarra Resources (ASX:ERW) recorded an impressive 120% gain after strategically acquiring:
- 70% interest in the historical Elizabeth Hill silver project
- 70% of the silver rights to the adjacent Pinderi Hills project
- 70% ownership of three exploration tenements surrounding the silver project
Elizabeth Hill Mine Potential
The Elizabeth Hill project is located in Western Australia's mineral-rich Pilbara region and encompasses a total area of approximately 180km². What makes this acquisition particularly compelling is the project's historical production record.
During its brief operational period around 2000, the Elizabeth Hill mine produced approximately 1.2 million ounces of silver from just 16,000 tonnes of ore, reflecting an extraordinary grade of 2,194g/t Ag. This positions it among the highest-grade silver deposits globally.
Significantly, the mine ceased operations after just one year due to depressed silver prices at that time, rather than resource depletion. With silver prices now substantially higher, the economics of resuming production appear considerably more favorable.
Reflecting this new direction, the company has announced plans to rename itself West Coast Silver (ASX:WCE), subject to shareholder approval, highlighting its strategic pivot toward silver development.
Metallurgical experts note that the Elizabeth Hill deposit has unique characteristics. "The silver mineralization at Elizabeth Hill includes occurrences of native silver, which can substantially reduce processing costs compared to more complex sulfide ores," commented a precious metals consultant who has examined the deposit.
