What Highfield Resources does

Highfield Resources is an ASX-listed (ticker: HFR) potash development company advancing a portfolio of 100%-owned projects in Spain, with its flagship Muga Project positioned as a future high-margin potash mine targeting European and global agricultural markets. The company operates through its wholly-owned Spanish subsidiary GEOALCALI, S.L.U., headquartered in Pamplona, Navarra, and employs conventional underground mining and solution mining techniques to extract sylvinite ore for processing into muriate of potash (potassium chloride). The project portfolio includes the Muga Project (currently in construction, with mining concession granted in July 2021 and final construction approval received in March 2023), the brownfield Sierra del Perdón Project (covering approximately 120 km² southeast of Pamplona, with historical mines that produced nearly 500,000 tonnes per annum from the 1960s until the late 1990s), and the Pintanos Project (exploration-stage with a maiden Mineral Resource Estimate of 70.7Mt at 11.9% K2O). The company also references a strategic North American opportunity via the Southey potash project in Canada.

The business is pre-revenue and currently in construction phase. The planned revenue model is B2B commodity potash sales — one-time license / direct sale — targeting agricultural cooperatives, fertilizer distributors, and industrial users through direct sales relationships and long-term supply agreements. The GTM is sales-led with a global geographic reach spanning EMEA, North America, and Oceania. In May 2025, Highfield signed a non-binding Letter of Intent with Qinghai Salt Lake Industry Co. (a subsidiary of China Minmetals Corporation, China's largest potash producer) for a US$300 million equity subscription, supplemented by a stand-by loan facility from EMR Capital Resources Fund III, LP. The QSL partnership represents a transformational financing milestone and broadens the company's strategic positioning into a globally diversified potash developer, while also introducing a Chinese state-owned enterprise as a major counterparty.

Products and services

• Muga Project A strategic potash development project in Spain supplying core European markets, forecast to be one of the highest margin potash mines globally. The project utilizes conventional underground mining and solution mining techniques for sylvinite ore processing.
• Sierra del Perdón Project A brownfield potash target located southeast of Pamplona covering approximately 120km², previously hosting two potash mines from the 1960s until the late 1990s producing nearly 500,000 tonnes of potash per annum, with potential for potash in new unmined areas.
• Pintanos Project A potash exploration project with a maiden Mineral Resource Estimate of 70.7Mt at 11.9% K2O, located in Spain.

Quantifiable outcome

• Forecast to be one of the highest margin potash mines globally

Direct peers

• K+S Aktiengesellschaft: European-headquartered potash producer (Germany) operating underground potash mines and selling MOP/SOP fertilizers into European and global agricultural markets. Most directly comparable to Highfield given European proximity and potash-only focus.
• ICL Group: Israel-based specialty fertilizer and potash producer with underground mining operations, selling potash to global agricultural markets. Comparable as a focused potash producer with international operations.

Broad incumbents

• Intrepid Potash: US-based potash and specialty fertilizer producer. Smaller scale than Nutrien or Mosaic but a relevant peer for understanding North American potash economics and underground solution mining techniques similar to those used at Muga.
• Nutrien Ltd: World's largest potash producer and a major crop inputs distributor. While vastly larger and diversified across nitrogen, phosphate, and retail, Nutrien is the relevant comparable for benchmarking global potash margins, pricing, and demand dynamics.
• The Mosaic Company: Major North American potash and phosphate producer. Less directly comparable geographically than K+S or ICL, but a key global benchmark for potash cost curves and pricing.

Emerging players

• Gensource Potash Corp: TSX-V listed junior potash developer using selective solution mining in Saskatchewan. Comparable as a small-cap potash developer pursuing innovative, lower-capex extraction techniques similar to those considered for Muga.
• Brazil Potash Corp: Development-stage potash company building the Autazes project in Brazil. Similar risk profile to Highfield — pre-revenue, large-capex underground potash development targeting agricultural end markets.
• Emmerson Plc: AIM-listed potash developer with the Khemisset project in Morocco. Closely comparable development-stage peer for European-listed junior potash developers focused on serving African and European fertilizer markets.
• Kore Potash: ASX-listed potash developer focused on the Sintoukola project in the Republic of Congo. Direct development-stage comparable for project financing, offtake structuring, and the path from feasibility to construction for junior potash developers.
• Western Potash Corp: Canadian potash developer (Milestone project in Saskatchewan). Relevant development-stage comparable for North American potash project economics, though Saskatchewan solution mining differs from Spanish underground methods.
