CSA Global Principal Geologist, Felicity Hughes recently presented at the Geological Society of Australia, SGEG Facets of Exploration virtual webinar on ‘Ore Control – Improving Economic Efficiency and Sustainability in Mining’ on Wednesday 14 July 2021.
This webinar formed part of a monthly series of online talks from industry professionals covering many aspects of exploration including carbonatites, exploration in mineral sands, regolith geochemistry in exploration and structural insights during exploration.

A geometallurgical approach during the early stages of the LoM cycle will deliver critical information required to understand, recognise, identify, and define those parameters, which can and will affect product recovery at the back end of the LoM. This critical path however is often overlooked until a much later stage in the cycle. An Ore Control model builds on resource or grade control models with the addition of critical information such as material and ore types, product recoveries, waste, acid consumption and reagent costs, defined at both a local and detailed scale (geometallurgical) as well as proposed mining scale (metallurgical). The use of an Ore Control model for control of mining and processing activities will deliver improved economic efficiency for the middle and back ends of the LoM cycle, provide opportunities for optimal recovery of product, and better ensure longevity and sustainability in mining practices.
Felicity is a geologist/geochemist and possesses more than 35 years’ experience in a wide range of commodities; ranging from grass roots exploration planning and management, due diligence, resource evaluation, feasibility, mine grade and ore control and geometallurgy. She has worked on the development and management of geological, beneficiation and geometallurgy models for a number of commodities. Felicity has worked in Australia, Brazil and Zambia and has successfully run her own consultancy for more than twenty five years.
