It’s been almost 360 years since the accidental isolation of phosphorus from urine by German alchemist Hennig Brandt who was searching for the elusive ‘philosopher’s stone’ – a mythical substance thought to transform base metals into gold.
Although he didn’t find what he was looking for, Brandt had stumbled across one of the key elements essential for life on Earth – from the very humans who inhabit the planet to the food we eat.
In medieval times, manures were the primary phosphorus fertiliser and were gathered from grazing animals and applied to crops. As Dr Richard Simpson writes in a June 2019 CSIRO report, boosting crop production by concentrating organic nutrient sources on part of the farm required a much wider land area for “nutrient foraging”, than the area on which the crop was grown.
Simpson, who at the time was a pasture agronomist with CSIRO, says mineral phosphorus fertilisers have been manufactured since the 1830s – firstly using bones, then guano, and now mostly from rock phosphate (rock deposits with about 8% phosphorus composition).
“The global use of mineral fertilisers escalated after the 1940s, when the food requirements of an expanding human population began to exceed our capacity to grow enough crop using organic nutrient sources alone,” he says.
“Good agronomy and scientifically-informed soil fertility management have guided Australia’s phosphorus fertiliser use. Wheat yields have increased three-fold since the 1880s.
“Phosphorus fertiliser was an essential component of this revolution, along with legumes, better crop varieties and improving farm technology. The productivity of Australian pastures has also been transformed by the combined use of superphosphate and pasture legumes such as subterranean clover.”
As part one of this feature series reveals, phosphate’s role in agriculture remains foundational although a new set of dynamics is reshaping investor interest and project development globally.
The world’s agricultural and energy systems are facing intensifying demand, and phosphate mining companies listed on exchanges such as the ASX (Australia), TSX, TSX-V, and the CSE (Canada) are carving out niche positions across both traditional fertiliser markets and emerging technology supply chains.
Their strategies today may define the industry’s landscape well into the late 2030s.
Here’s a closer look at the key players, what they are pursuing, and why the next few years will be pivotal for phosphate equities.
Australia’s growing phosphate exposure
Australia’s resource sector has long been synonymous with iron ore, gold and lithium but the phosphate story is quietly evolving.
One of the more advanced players in this space is Aguia (ASX:AGR), which will be turning on the processing plant at its Três Estradas project in Brazil with the aim of starting production mid-2026 and then ramping up to full capacity in 2027.
Aguia Resources is an ASX-listed multi-commodity company with pre-production phosphate projects located in Rio Grande do Sul (Brazil) and gold projects in Bolivar (Colombia). It has established highly experienced in-country teams based in Porto Alegre, the capital of Rio Grande do Sul (Brazil) and in Medellin (Colombia).
Speaking to Mining.com.au, non-Executive Chairman Warwick Grigor says 2026 is shaping up to be a transformational year for the company as it is eyeing cashflow opportunities and actively considering paying dividends to shareholders amid a refined growth strategy.
Aguia has signed seven letters of intent to sell 54,000 tons of Pampafos in Rio Grande do Sul and Uruguay. Smaller than Brazil,Uruguay focuses on high-quality food production, while Brazil is known for its large-scale agribusiness.
Uruguay strategically sources natural inputs like Pampafos to excel in the premium organic food market. Aguia has signed a letter of intent with Vettore to buy 5,000 tons of Pampafos for distribution in the country. To access this market, Aguia will register Pampafos there, which is expected by March 2026 and it will begin agronomic tests in-country.
In early December 2025, Aguia signed a technical co-operation agreement with Uruguay’s National Institute of Agricultural Research (INIA), the country’s leading authority on seed and fertiliser technology testing. Dr Jesus Castillo, INIA’s Technical Director, will lead three years of agronomic tests, joined by Brazilian researcher Dr Felipe Carmona, who has overseen Aguia’s agronomic trials in Brazil since 2019.
In the 2024/25 harvest, Uruguay produced 3.84 million tons of soybeans and 1.7 million tons of rice, along with notable amounts of wheat, corn, and barley.
“Remember, there’s two selling seasons for the phosphate – May, June, July, then November, December, January. What you have to do is build up your stockpile and sell it in those periods. So your cash flow is chunky twice a year”
Mine services and logistics contractor Contrasapper is nearing completion of the mine implementation plan at Três Estradas. Drainage systems for the sump area at the end of 2025 were finalised, and the upgrade of 9km of municipal road access has also been completed.
“Remember, there’s two selling seasons for the phosphate – May, June, July, then November, December, January. What you have to do is build up your stockpile and sell it in those periods. So your cash flow is chunky twice a year,” Grigor tells Mining.com.au.
“There’s always a chance to sell some in between, but the majority of your sales will be in those selling seasons. By this time next year, we’ll be at full capacity and we’ll be selling the product, and we’ll be getting ready to double production again, which might take six months of putting in another rotary kiln so that by maybe September quarter ’27, maybe we commission that.”
At that stage Aguia’s cash flow is expected to double to $40 million a year.
While Aguia has gold projects in Colombia, despite the ever-increasing gold price “there’s nothing in the share price for the gold”, says Grigor, adding “it’s all about the phosphate”.
“The phosphate selling on a prospective cash flow multiple at one or two times, which is very cheap. Anyone who wanted to sell the shares who are disappointed in the gold, the chances are they’re gone,” the non-Executive Chairman says.
“But we are fortunate that we have such a good project in phosphate that we can restore the value. When I got involved in the company, it was about one cent per share. It’s now twice that.”
Aguia’s share price was sitting at $0.019 at the time of writing.
Avenira
Emerging junior Avenira (ASX:AEV) controls the Wonarah phosphate project in Australia’s Northern Territory, one of the country’s largest known phosphate deposits by contained phosphate content.
Avenira is aiming to establish a local, integrated supply chain delivering products into the agricultural and industrial chemical markets.
The company says feedstock from its Wonarah Phosphate Project can enable the production and sale of three product streams – early revenue generation with direct shipping ore (DSO) phosphate, to supply into the fertiliser markets and for Yellow Phosphorous and Thermal Phosphoric Acid production; thermal Grade Phosphoric Acid (TPA); and Yellow Phosphorous (YP).
Avenira’s exploration strategy touches both fertiliser markets and potential supply to LFP battery value chains – a dual horizon that reflects the evolving commercial demand for phosphate as both an agricultural staple and a strategic industrial mineral.
Canadian Phosphate
Formerly known as Fertoz, ASX-listed Canadian Phosphate (ASX:CP8) is a mineral exploration company focused on advancing its Wapiti and Fernie sedimentary rock phosphate projects in British Columbia, Canada. A key component of fertiliser and lithium iron phosphate battery production, Canada imports 99% of its phosphate needs from around the world.
CEO Daniel Gleeson says the name change better aligns the organisation internally, future business partners, as well as current and future investors. The company recently reorganised its corporate structure and strategy to focus squarely on its sedimentary rock phosphate projects in British Columbia.
Its flagship Wapiti and Fernie projects are situated in major agricultural regions, and the company is advancing exploration, corporate funding and potential production pathways. The repositioning, including a strategic share placement in late 2025, reflects investor interest in phosphate’s broader economic role beyond its historical niche.
The company says the name change reflects its revised strategy of maximising its phosphate tenements for the production of phosphoric acid, which is a precursor for the use in conventional phosphate fertiliser and lithium iron phosphate (LFP) battery production, as reported by Mining.com.au.
The company is aiming to expand its Wapiti Project’s mineral resource estimate, which contains an inferred and indicated resource of 1.54 million tonnes @ 21.6% phosphorous pentoxide at a 7% cut-off grade.
Dahrouge Geological Consulting has also been appointed to develop a geological model of the resource, using existing exploration data to develop a JORC-compliant exploration target of Wapiti beyond the initial depth of 30m.
The geological model will facilitate a focused exploration plan to efficiently target phosphate-bearing horizons and maximise the project’s potential. In conjunction, an exploration drilling program has been proposed to be conducted sometime this year.
PhosCo
ASX-listed PhosCo (ASX:PHO) focuses on assembling a district-scale phosphate portfolio, particularly in the Northern Phosphate Basin of Tunisia.
The company’s vision is to support a potential world-class fertiliser hub by leveraging strategic local resources and expertise.
PhosCo says its strategy underscores the enduring agricultural demand for phosphate rock and positions the company to capitalise on global fertiliser markets as food security pressures persist.
PhosCo’s wholly owned Gasaat exploration permit is in Tunisia’s Kasserine region. The permit covers an area of 112km2 and forms part of PhosCo’s plan to develop Tunisia’s Northern Phosphate Basin, in partnership with the community. The Gasaat permit encapsulates the former Chaketma project, including interpreted extensions of the deposit.
The bulk of its phosphate is located at the base of a massive limestone unit close to the top of a high segmented plateau, which is divided into distinct domains or prospects by a series of normal faults.
Drilling results have produced consistent, wide, high-grade phosphate mineralisation close to surface, with 50% of the prospect’s known surface mineralisation yet to be drilled.
PRL (formerly Centrex Metals)
Another established Australian player is fertiliser company PRL Group (ASX:PRG), which acquired Centrex Metals in September 2025 and now owns the Ardmore phosphate rock mine in Queensland via its Agriflex subsidiary.
Ardmore is a producing asset with JORC-compliant reserves and has inked offtake deals with significant fertiliser buyers. The company continues to expand production and also explore opportunities in higher-value downstream products, including potential links with lithium iron phosphate (LFP) battery material initiatives.
The Ardmore phosphate rock mine has a mineral reserve of 10.1 million tonnes at 30.2% phosphorus pentoxide contained within an existing mineral resource of 16.2Mt.
Canada’s phosphate opportunity
Canada’s phosphate sector has seen growing activity on the TSX Venture Exchange (TSX-V) and Canadian Securities Exchange (CSE) in recent years, buoyed by both global fertiliser demand and its addition to the Canadian critical minerals list in 2024 – with phosphorus recognised alongside silicon metal.
One of the better-established names on the TSX Venture is Arianne Phosphate (TSX-V:DAN), a developer of the Lac à Paul project in Québec. Featuring some of the largest phosphate reserves in Canada, Lac à Paul holds hundreds of millions of tonnes of phosphate ore.
The company says its scale makes it a potential cornerstone for both fertiliser supply and industrial applications in North America over the next decade and beyond.
Beauce Gold Fields
While traditionally known for gold, Beauce Gold Fields (TSX-V:BGF) has expanded into phosphate exploration, holding dozens of prospective projects across Québec.
The company welcomed phosphorus’s designation as a critical mineral, a shift that elevates investor attention and suggests a broader strategic pivot among Canadian juniors.
Chatham Rock Phosphate
Chatham Rock Phosphate (TSX-V:NZP) is advancing phosphate projects both in Canada and overseas, including the Korella North mine in Queensland, Australia, intended to supply direct-application phosphate to agricultural markets.
Environmental approvals and infrastructure planning are central to its progress as the company positions itself for first production.
Chatham Rock Phosphate aims to be the premier supplier of direct application phosphate to the New Zealand and global agricultural sector.
Meanwhile, on the Canadian Securities Exchange (CSE), one standout name has emerged as a dedicated phosphate play with both supply and processing ambitions – First Phosphate Corp (CSE:PHOS).
First Phosphate is a vertically oriented development company holding a large land position in Saguenay-Lac-St-Jean, Québec with high-purity igneous phosphate deposits that are especially attractive for both fertiliser feedstock and lithium iron phosphate (LFP) battery material production.
The company has been active in raising capital for exploration and advancing its Quebec projects through private placements and logistical planning for infrastructure that could support regional export hubs.
Recent corporate milestones include its inclusion in the CSE25 Index, a recognition the company hopes may broaden investor visibility and institutional interest.
First Phosphate has also supported investment in port infrastructure at Saguenay, which is a strategic move that could enable efficient outlets for future concentrate and processed product shipments.
The company’s strategic positioning reflects a shift from pure exploration toward midstream integration and supply chain participation where cathode materials for LFP batteries represent a significant growth vector.
Critical minerals and multi-market demand
Across exchanges and borders, listed phosphate companies are navigating a landscape defined by dual end markets – traditional fertiliser and emerging battery chemistries like LFP. This bifurcation matters because it widens the total addressable demand, bringing industrial and energy transition investors into what was historically a predominantly agriculture-focused commodity.
Canada’s policy recognition of phosphorus as a critical mineral aligns with global shifts toward securing supply chains for essential materials. This trend could unlock new funding, permitting support, and offtake agreements that improve project bankability through the late 2020s.
Meanwhile, Australian-listed players are capitalising on abundant phosphate resources at home and abroad, combining project development with strategic offtake and feasibility studies that extend beyond simple rock extraction — notably into fertiliser manufacture, organics and potentially LFP feedstock.
Over the next five years to 2030, phosphate mining’s listed cohort faces both opportunities and challenges. For many juniors, the immediate focus is advancing resources to defined reserves, completing definitive feasibility studies, securing offtake agreements, and building infrastructure linkages that reduce project risk.
Projects with proximity to agricultural demand hubs or transport corridors such as Wapiti, Fernie and Saguenay may attract earlier market attention. At the same time, high-purity phosphate plays that can support LFP battery cathode production may command strategic premiums, especially as EV manufacturers and energy storage sectors seek secure, Western hemisphere feedstocks.
What unites these diverse companies is a shared strategic imperative – transforming phosphate from a commodity once pigeonholed as a fertiliser input into a multifaceted mineral asset that serves both enduring agricultural needs and emerging industrial supply chains.
For investors and mining observers, analysts believe the coming cycle may be defined not by commodity supercycles, but by supply chain positioning and the ability of listed phosphate miners to bridge traditional and future markets — turning what was once an overlooked sector into a quietly pivotal part of the minerals landscape by 2030.
