Name of the Project
Achmmach tin project.

Location
The project is located about 40 km south-west of Meknès, in central northern Morocco.

Project Owner/s
Atlantic Tin completed the acquisition of  Société Anonyme d’Entreprises Minières (Samine)  from Managem on August 5, 2024. Samine owns the previously producing El Hammam mine, including its infrastructure and tenements, adjacent to the Achmmach project. 

Project Description
The project incorporates the benefits of combining the Achmmach project with the nearby El Hammam processing facility. 

The May 2024 scoping study proposes the production of 63 700 t tin metal in concentrate over a 17-year mine life, with peak production estimated at 5 000 t/y of tin metal in concentrate.

Conventional longhole open stope mining methods with back fill will be used, and will include  mined-ore upgrades with ore sorting and dense-media separation.

Conventional crushing, gravity, high-pressure grinding rolls milling, and flotation, will be used to produce tin concentrate.

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 $307-million in the base case and an internal rate of return of 45% at $30 000/t tin. Payback is estimated in 4.3 years.

Capital Expenditure
Preproduction capital expenditure (capex) is estimated at $54-million. Expansionary capex in years 2 and 3 is estimated at $28-million.

Planned Start/End Date
Not disclosed.

Latest Developments
Atlantic Tin has announced a resource upgrade, to 39.1-million tonnes at 0.55% tin for a total of 213 000 t of contained tin.

This mineral resource estimate has been prepared by independent consultant Cube Consulting, of Western Australia, in accordance with the 2012 edition of the Joint Ore Reserves Committee Code.

Although the addition of lower-grade ore, owing to the change in the cutoff grade, reduces the grade of the total resource, the mine plan will focus on targeting the highest-grade stopes first and using an elevated cutoff grade to ensure that the feed grade to the processing plant is maximised in the early years of production, the company has said.

The increased estimate will form the basis of the current feasibility study of the combined Achmmach–Samine project. 

An updated ore reserve estimate will be produced once the current technical studies are sufficiently advanced.

Key Contracts, Suppliers and Consultants
