Antofagasta Minerals
Study Leader for the expansion study of Minera Las Pelambres, a large open pit copper mine, in which a major integrated study was carried out to define the optimal project development strategy under constraints including tailings placement, hydrogeology, hydrology, environmental permitting and social impact. 

Reconciliation Studies

Underground nickel mine - Western Australia
Development of procedures and reporting systems.
Underground gold mine - Western Australia
Review of spreadsheet based systems for mining and milling.

Other Grade Control Studies

Open pit gold mine - Western Australia
Audit of grade modelling and ore blocking procedures.
Open pit gold mine - West Africa
Compliance of systems with current best practice.

Open pit gold mine - Western Australia

Review of sampling procedures for grade control and toll milling.

Underground gold mine - Queensland
Training oriented towards new system development.
Open pit iron ore - Western Australia
Grade control drilling system.
Delta Gold NL
Developed the geological modelling for the Golden Feather Feasibility Study resource estimation of four deposits comprising the Golden Feather Project, near Kalgoorlie, Western Australia.  Subsequently reviewed the grade control procedures and in particular the optimisation of ore blocking procedures using conditional simulation.
Anglo American Base Metals
Implemented and led the ongoing series of rolling audits for Mantoverde open pit copper (Chile), Loma de Níquel open pit lateritic nickel (Venezuela), Lisheen underground zinc-lead (Ireland), El Soldado open pit copper (Chile), Skorpion open pit zinc-lead (Namibia) and Los Bronces open pit copper (Chile). 
Manganese mines -  Australia and Africa
Managed the Independent Competent Person report on Ore Reserves for the London Stock Exchange.
Lynas Gold NL
Developed the geological modelling for the Mt Olympus Feasibility Study resource estimation of the Mt Olympus gold project near Paraburdoo, Western Australia.  The ore reserve estimate was subsequently supported by the development and implementation of grade control procedures including the optimisation of ore blocking using conditional simulation..
Study Leader for the Pre-Audit technical review of the Codelco copper operations which evaluated the resources, ore reserves, mining parameters and production performance to define the value of Codelco Corporation.  Also led the  exploratory and definitive planning study for the Salvador block caving and open pit copper mining operations. 

Corporate Advisory

St Barbara Minerals
Led the feasibility study aspects for the Paulsens Deposit of resource and ore reserve estimation that included legacy data recovery, resource estimation, ore reserve estimation, open pit and underground mine planning studies, grade control studies and conditional simulation to model expected mining dilution.  The project was deferred following a corporate takeover.


Commodity & Project Experience

Magnetite Iron Project - Western Australia
Project Director for engineering consultant's involvement in the development of this major project.  Work involved auditing, estimation of resources, establishment of the development drilling operations comprising a camp of 80 people, supervision of drilling, data collection and database systems, geophysical surveys, development of safety protocols, technical resolution of issues, coordination of geotechnical and rock mechanics studies, development of full GIS support for the client, and liaison with the client’s environmental, project construction and social impact teams.
Gold mines - Western Australia
Managed the independent audit and reporting to establish the basis of geological modelling, resource estimation and ore reserve reporting for all the operating underground and open pit mines.
