PhosCo’s KM Discovery: High-Grade, Shallow Phosphate Could Fast-Track Production in a Supply-Starved Market

PhosCo has confirmed a major new discovery at the KM prospect within its Gasaat phosphate project, following maiden drilling that returned some of the highest-grade assays yet recorded in Tunisia. The program intersected broad, shallow zones of phosphate mineralisation, including a standout 53 metres at 22.3% P₂O₅. More critically, nine separate samples from the zone grade above 28% phosphate-rare grades that highlight KM as a standout addition to the project's pipeline.

The economic implication of this shallow depth is significant. Because the mineralisation occurs close to the surface, the discovery points to a low strip ratio and reduced mining costs compared with deeper deposits. This makes KM not only high-grade but also inherently cost-competitive, a combination that significantly enhances its development potential. The company is now fast-tracking assays from the prospect, expecting results later this month, and has mobilised its drill rig to the nearby SAB prospect for confirmatory drilling to support a maiden Mineral Resource Estimate.

The potential resource estimate for KM is substantial, with a new exploration target estimating it may contain as much as 26 million tonnes. This would strengthen the overall project economics, particularly if developed early. The discovery's proximity to the proposed processing plant magnifies its importance, allowing PhosCo to bring the project online more quickly and with lower capital intensity than more remote deposits. The company believes these results and the upcoming resource estimate will significantly improve the project's economics ahead of the planned bankable feasibility study.

In short, the KM discovery is a high-grade, shallow addition that strengthens the Gasaat project's profile. It offers a path to earlier, lower-cost production and robust cash flow. However, its ultimate impact depends on the pace of development and the strength of the phosphate market, which will determine whether this promising resource translates into accelerated project economics.

Global Phosphate Supply-Demand Balance: Elevated Prices Signal Tightness

The market for phosphate is under clear strain, a condition that makes a new project like Gasaat relevant. The key price metric is anhydrous phosphate fertilizer, which reached $1,035/ton in late March 2026. That level marks a 20% jump from a month prior and is the highest price in over three years, signaling a tight supply-demand balance.

This tightness has been exacerbated by a major supply shock. On 14 March 2026, China suspended all exports of phosphate and phosphate-containing fertilisers. As a dominant global supplier, this move directly tightened the market, removing a key source of fertilizer and raw materials. The impact is compounded by geopolitical risks, with the Iran conflict intensifying supply chain vulnerabilities, particularly for Gulf-based producers who handle a large share of global trade.

Yet demand pressure persists. Global fertilizer use recovered in 2024 to a new record, driven by a rebound from the lows of 2021-2022. However, the current elevated price environment is now driving demand destruction. Farmers are reducing application rates, a classic sign of affordability issues. This creates a complex dynamic: while total nutrient use is still growing, the high cost is curbing growth and creating volatility.

The bottom line is a market under pressure from multiple directions. Supply has been disrupted by China's export suspension, while demand is being pulled back by high prices. This combination of reduced supply and constrained demand growth is what is pushing anhydrous prices toward multi-year highs. For a new project, this setup means there is a clear need for alternative sources, but it also means the project will enter a market where price stability is uncertain.

Gasaat's Development Pathway: Funding, Scale, and Tunisia's Revival

Turning the KM discovery into a functioning supply source requires navigating a clear but capital-intensive pathway. The first critical step is securing funds for the bankable feasibility study (BFS), which is the project's next major milestone. PhosCo has launched a fully underwritten A$5-million entitlement offer, with key insiders committing to priority sub-underwriting. This is backed by a $1.5-million loan from the company's MD and major shareholder to fast-track work. On the strategic front, the company has signed a mandate letter with the European Bank for Reconstruction and Development (EBRD) for a potential $5-million strategic investment. These combined efforts aim to de-risk the project and provide the capital needed to advance the BFS, which will determine the final economic model and financing plan.

The project's scale provides a long-term foundation. A 2022 scoping study modeled a 46-year, 1.5 million tonne per year operation with a two-stage development plan. This long life and steady production profile are key to the project's appeal. The discovery of KM, with its high-grade, shallow mineralisation, offers a potential lever to accelerate the timeline. The company is actively investigating ways to accelerate the development of its new KM phosphate discovery, aiming to bring this low-strip resource online earlier to enhance near-term economics.

This development path is supported by a powerful national policy shift in Tunisia. The government is setting ambitious goals to revive its phosphate industry, aiming to boost production five-fold to 14 million metric tons by 2030. This strategic plan is a direct response to the industry's decline and positions the country to capitalize on high global fertilizer prices. For PhosCo, this creates a favorable operating environment, with a government eager to attract investment and restore Tunisia's status as a major exporter.

The pathway from discovery to production is now defined. It hinges on the successful completion of the BFS, funded by a mix of equity, debt, and strategic investment. The project's inherent scale and the national policy push provide a strong tailwind. If the BFS confirms the economics, PhosCo could move toward construction, with the KM discovery potentially serving as an early, high-margin source of feedstock. The journey is clear, but the next few months-focused on assay results, the BFS, and securing final financing-will determine how quickly that vision becomes reality.

Catalysts, Risks, and What to Watch

The path from a high-grade discovery to a functioning supply source is now defined by a series of near-term milestones. The primary catalyst is the completion of fast-tracked assays and metallurgical testing for the KM prospect, with results expected later this month. This data will be the first concrete test of the resource's quality and processability, directly feeding into the project's economic model. Success here would validate the company's push to accelerate development and could significantly improve the outlook ahead of the bankable feasibility study.

The key risk to the long-term thesis is the pace of demand destruction. While global fertilizer use has recovered to a new record, the current extremely elevated prices are pulling back on farmer applications. If high prices persist, this demand destruction could intensify, weakening the long-term price outlook that the project's economics rely on. The market's tightness is a double-edged sword: it creates a need for new supply, but also a vulnerability to affordability-driven slowdowns.

Investors should watch three critical developments. First, progress on securing the $5-million strategic investment from the European Bank for Reconstruction and Development. This commitment is a key signal of institutional confidence and will help de-risk the project's next phase. Second, the outcome of the bankable feasibility study itself, which will determine the final capital cost, production schedule, and financial returns. Third, the company's ability to move from discovery to development, as seen in its mobilisation of the drill rig to the SAB prospect for confirmatory work. These are the milestones that will either validate the project's promise or reveal the friction and cost that can delay new supply.
