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.

Recent Significant Studies by Mintrex
Mintrex collects metrics against their study and project estimates to gain a better
appreciation of how well we are performing in terms of estimate accuracy.
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.

Turnkey/EPC contractors for project implementation.

Most recently on the Tomingley Gold project, Mintrex performed the EPCM and the project metrics were:

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.
