What Emmerson does
Emmerson Plc is a London-listed (AIM: EML) potash development company incorporated in the Isle of Man that has been developing the Khemisset Potash Project in Northern Morocco since founding in 2015. The asset sits on a 537Mt @ 9.24% K2O JORC Resource (375.2Mt Indicated, 161.8Mt Inferred) with a planned 19-year initial mine life producing approximately 810,000 tonnes of K60 Muriate of Potash per annum, alongside by-product struvite and vivianite slow-release fertilizers enabled by its patented Khemisset Multi-mineral Process (KMP).
The company's core technology is KMP — UK Patent No. 2634094 — a processing architecture that reduces water consumption by 50%, lifts MOP recovery from 85% to ~91%, and produces two additional high-value slow-release fertilizers from magnesium- and iron-rich brines. Feasibility Study economics position net capex at US$525 million (bottom-quartile capital intensity, less than half the global peer average), with post-tax NPV8 of US$2.2 billion and 40% IRR incorporating KMP. The project has been halted since the rejection of its Environmental and Social Impact Assessment by Morocco in October 2024, with the company now focused on a US$1.215 billion ICSID arbitration claim against Morocco, KMP IP licensing exploration, and remediation work at the former Mine de Centre site.
The operating model has contracted to a single full-time CEO, a Chairman, and one non-executive Director. Revenue is non-existent today; future monetization is planned through two streams — potash mining and sales to African, European, Brazilian and US fertilizer markets, and licensing of the KMP technology to other carnallitic and rinneitic potash deposits globally. The current funding cycle — including a £750,000 placing in March 2026 — is dedicated to arbitration proceedings and IP development rather than mine construction.

Products and services
- Khemisset Potash Project Potash mining development project located in Northern Morocco with a JORC Resource Estimate of 537Mt at 9.24% K2O, targeting approximately 810,000 tonnes of K60 MOP per annum over a 19-year mine life; the company's single core operating asset.
- K60 MOP (Muriate of Potash) Standard potassium chloride fertiliser with minimum 60% K2O grade used to increase crop yields and improve plant quality; the primary planned saleable product from the Khemisset Project targeting large fertilizer distributors and agricultural customers.
- Khemisset Multi-mineral Process (KMP) Proprietary potash processing technology covered by UK Patent No. 2634094 that reduces water consumption by 50% and increases muriate of potash recovery from 85% to approximately 91%. Also produces two high-value slow-release fertilisers (struvite and vivianite) from magnesium and iron-rich brines, with potential to be licensed for use at other carnallitic and rinneitic potash deposits globally.
- Struvite High-value, slow-release multinutrient fertiliser produced as a by-product of the Khemisset Multi-mineral Process, used to combat phosphate run-off and reduce application rates for farmers; suited to the African and premium fertilizer markets.
- Vivianite High-value, slow-release fertiliser produced as a by-product of the Khemisset Multi-mineral Process, particularly suited to the African market as a premium multinutrient product.
Quantifiable outcome
- Water consumption reduced by 50% and process water by 60% compared with 2020 Feasibility Study
