MINTREX STUDIES AND PROJECTS
MINTREX STUDIES AND PROJECTS Mintrex Studies Mintrex has completed many studies over the years in Australia and internationally, including several projects that have been banked on the back of our studies.

Mintrex Projects Mintrex has completed projects in roles as varied as Client Representative and Construction Manager, although most have been either EP (engineering and procurement – typically for operating companies who owner-construct) or EPCM (engineering, procurement and construction management) roles. Some examples of EP project estimate accuracy history are included below: The following projects were engineering and procurement (EP) projects completed by Mintrex where the client constructed the plant. In all cases the EP was performed as a lump sum and variations were specific client requests, acknowledged as not in scope at the time they were requested. In all cases the (client requested) variations were not more than 12% of the lump sum originally contracted and in two of the contracts (Moolart Well and Garden Well) there were no variations to the contract claimed. The cost performance index (CPI = earned value/ actual cost = budget/actual cost, when complete) has been drawn from client feedback and the public record. In all cases the schedule performance index (SPI) is unknown, because the construction management was not undertaken or reported by (or to) Mintrex.

Most recently on the Tomingley Gold project, Mintrex performed the EPCM and the project metrics were: Project CPI SPI Budget $ Final Cost$ Tomingley 1.02 1.0 $116M $113.7M The SPI was 1, with ore to the plant one day ahead of schedule. EPC and EPCM Project Estimate Accuracy Mintrex has completed a number of brownfield upgrade projects in both Australia and internationally, with brownfield projects recently completed in Australia, Mali, Ghana and in the Philippines. The Mintrex scope within these projects has focused on the client requirements to complete their project. On different occasions, the engineering and support provided has included option studies, process optimization, re-engineering, equipment upgrades and replacement, remedial and repair work, procurement support for contracts, engineering design and expediting, project management, construction management and client representation. Recent commissioning photo from the Mali installation, which is a low cost pebble crushing application (limited mine life). This design, including shop detailing, was completed for a lump sum price. The works were owner-constructed in Mali. Commissioning time from connection of power and commencement of electrical and mechanical testing, until plant running was achieved in less than 5 days.
