Mandate
Signed mandate
Engaged under a multi-million-euro mandate to deliver the Definitive Feasibility Study for a potash (carnallite) solution-mining development in Central Africa: contracted to AACE Class 1 accuracy on capital cost, with operating- and energy-cost estimates held to the same contractual accuracy requirement; well-field and cavern design; long-term creep, triaxial and shear geomechanics with a full rock-mechanics model; complete plant engineering including HAZOP, P&IDs and single-line diagrams; and investment-grade economic evaluation.
Context
Solution mining lives or dies on geomechanics. A definitive study for a carnallite development has to prove the caverns before it prices the plant.
Approach
The mandate spans well-field and cavern design, long-term creep, triaxial and shear testing with a full rock-mechanics model, complete plant engineering through HAZOP, and investment-grade economic evaluation, contracted to an AACE Class 1 accuracy requirement on capital cost.
Standards
AACE Class 1 (contractual estimating obligation) · international geophysical and geological practice · OHADA contracting
Supported the exploitation-licence application for the same development: technical studies and permitting presentation.
