Gavin Ferguson has a long practical experience in technical, production and the financial aspects of evaluating mining projects world-‐wide. He has undertaken, design and evaluation work for surface and underground mines in Africa, Australia, Brazil, Canada, Central America, Chile, Europe, countries of The Middle and Far East, Peru and the United States of America. He assisted Codelco-‐Chile with: the adoption of protocols for the estimation of resources and engineering of reserves; and served on the Geomechanics Board for the El Teniente Division. Gavin has acquired specific skills with respect to: deriving economically beneficial strategies at the scale of mine extraction and corporate development; and implementation of costs and productivity strategies to position companies to prosper against the backdrop of the long term decline in metals prices. Recent work, most relevant to today’s mining industry is the involvement in risk analysis and developing risk management strategy and risk response plans for both operating mines and mining projects.

Principal skills include:

− Technical & Economic Audit of Operations and Capital Projects − Due Diligence of Resource & Reserves Declarations − Strategic Planning (Mineral Reserves, Equipment & Manpower) − Risk Assessment, Project Ranking, Preliminary & Full Feasibility Evaluations − Geomechanics Engineering in Mine Planning − Mine Planning & Design − Review of Study Reports
