Name of the Project
Khemisset potash project.

Location
Northern Morocco.

Project Owner/s
Potash developer Emmerson PLC.

Project Description
A feasibility study completed in June 2020 confirmed Khemisset as a world-class, low capital cost, high-margin potash mine. Building on the feasibility study, Emmerson has completed a concept study to examine the potential to develop Khemisset using a four-phased approach to reduce upfront capital costs and execution risk, and plan additional expansion stages to ensure that its economic value is fully developed.

The first phase focuses on a reduced muriate of potash (MoP) output stage, with the development of the declines and mine similar to the feasibility base case, but with a reduced capacity process plant, which will result in lower upfront capital expenditure (capex). MoP production is estimated at 350 000 t/y.

The second phase expands MoP production to the same level as in the feasibility study, with the addition of one-million tonnes a year of de-icing salt being produced as envisioned in the feasibility study. The additional capex required facilitates the expansion of the process plant capacity, along with the salt production plant and additional costs in mine development. An estimated 385 000 t /y of MoP is expected to be produced, as well as one-million tonnes a year of de-icing salt.

Phase 3 entails the establishment of a sulphate of potash (SoP) production facility, expected to be located at the Port of Jorf Lasfar. The additional capex required is for the construction of the SoP facility and the expansion of the salt production plant. An estimated 240 000 t/y of SoP is expected to be produced and one-million tonnes a year of de-icing salt.

The final phase includes the development of the south-west area of the resource through two new declines, with the ore being transported to the existing process plant that is expanded to increase its capacity to more than one-million tonnes a year of MoP, a portion of which provides feed for the SoP facility. About 270 000 t/y of MoP is expected to be produced in this phase. This phase will also result in the production of two-million tonnes a year of de-icing salt.

At full production,  Khemisset could produce 800 000 t/y of MoP, 240 000 t/y of SoP and four-million tonnes a year of de-icing salt.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has a net present value, at an 8% discount rate, of $2.37-billion.

Capital Expenditure
The capital cost of the project, including contingency, is estimated at $710-million.

Planned Start/End Date
Emmerson intends to start construction of the Khemisset project by the end of 2021.

Latest Developments
Emmerson says the environmental approval process for its Khemisset potash project is progressing well, with all technical work having been completed and submitted.

The company expects final approval from the country’s Environmental Evaluation Committee imminently.

Meanwhile, Emmerson has also lodged applications for the renewal of remaining research permits that were not part of the mining licence area, with a positive outcome on these expected during the third quarter of this year.

The company has started a tender process for technical field works to address risks determined in the feasibility study of the project, as well as preparing data for use in the engineering design workstreams.

Emmerson’s workstreams are on course for early construction works to start by the end of the year, including debt-funding due diligence.

Key Contracts, Suppliers and Consultants
