Name and Location
Achmmach tin project, Morocco.

Client
Kasbah Resources.

Project Description
Achmmach has a maiden ore reserve of 8.45-million tonnes at 0.78% tin for 65 400 t of contained tin.

The definitive feasibility study (DFS) base case has determined that a one-million-tonne-a-year underground operation at Achmmach is technically and commercially feasible.

The base case is premised on underground extraction of the entire Meknès trend ore reserve using long-hole open stoping (LHOS) mining methods, sup-ported by pastefill delivering about one-million tonnes a year of run-of-mine (RoM) ore to a conventional gravity and flotation facility at Achmmach.

This processing plant will produce an estimated 10 000 t/y of low-impurity tin concentrates at about 55% tin and generate about 5 300 t/y of tin in concentrate for export.

The LHOS method is well suited to the Achmmach orebody geometry and rock mass competence, and will allow for good ore recoveries with minimal dilution.

Value
Preproduction capital costs for the project are estimated at $181-million.

Duration
Production is expected in 2016.

Latest Developments
Since the completion of the Achmmach DFS, announced in March 2014, Kasbah has advanced several initiatives to further enhance the DFS base case financial model. The recent emergence of the Western zone (WZ) as a high-grade and valuable component of the larger Achmmach mineral resource has provided further value-add opportunity, where the integration of the WZ into the DFS mine plan, the application of metallurgical enhancements and the ultimate refinement of the mine reserve could significantly enhance early-stage cash flow and reduce project capital requirements.
Refining the existing DFS mine design to incorporate the WZ provides the opportunity to access and schedule high-grade ore from the WZ early in the mine development, with consequent benefits to overall mine economics.

The indicated resource reported for the WZ represents an estimated 4 200 t of contained tin that have not been included in the current mine inventory. Further, the connection of the well drilled Meknes Trend to the lightly drilled Sidi Addi Trend will provide additional exploration access to the highly prospective Sidi Addi trend.

By integrating the WZ into the overall mine design, Kasbah also has the opportunity to refine development scheduling, waste and paste fill management, ventilation and stope design, with possible reduction in overall mine capital.
Kasbah is investigating options, such as dry stacking the tailings, to enhance water conservation and reduce tailings management facility construction costs.
These value-adding programmes will be completed during the first quarter of 2015 and, if successful, should significantly enhance the early-stage cash flow from Achmmach as higher-grade, higher-margin ore is processed.

Consequently, Centamin will extend the project financing process to take advantage of these potential project value-add opportunitites.
