On September 18th, join us in Vancouver for our free lunch and learn session as SGS’ Sarah Prout presents “Early Stage Metallurgical Evaluation (ESME): An Early Stage Indication of Metal Recovery using Metallurgy and Mineralogy”. This presentation will detail how using an SGS developed package targeted at early stage programs can help provide data including metal recovery and the possible flowsheet configurations earlier in the project life cycle to provide future direction of the project.

Many junior, mid-tier and senior mining companies have various properties within their portfolio; due to the present economic conditions where exploration budgets can be limited, there is a need to make decisions on where to focus drilling activities and have additional robust information to raise financing along with the identification of potential JV opportunities.  Understanding the metal recovery will help to support these decisions. 

SGS has developed an early stage program, designed to provide information on metal recovery and mineralogy (and ARD potential of the tailings produced) all as a cost-effective package.  For gold deposits, the sample will be submitted for head mineralogy and assaying, gravity recovery using a laboratory scale Knelson concentrator, with the Knelson concentrate submitted for assaying and mineralogy, the Knelson tailing submitted for rougher flotation, with the rougher concentrate submitted for assaying and mineralogy and the rougher tail submitted for cyanide leaching.  Whereas with copper projects, the sample will be submitted for head mineralogy and assaying and rougher flotation.

This data can then be used to provide an early indication of metal recovery and the possible flowsheet configurations to provide future direction of the project.



  • How does a project develop from prospecting to production through to closure and where does metallurgy fit in?
  • What is metallurgical testing and the types of testwork?
  • Where does mineralogy and ARD fit into the picture?
  • Early indication on direction of exploration project and it’s potential after drilling – where is your money going?



Sarah Prout, Ph.D.

Sarah Prout is Manager, Metallurgy, Vancouver Operations. Prior to taking on the role, sarah served as Senior Mineralogist for 8 years. Sarah received her Ph.D. in mineralogy, petrography and economic geology in 2004 from Camborne School of Mines in the UK. Sarah has over a decade of geology and mineralogy experience. Sarah started her SGS career in January 2007 as a Mineralogist based in Lakefield and joined the SGS Canada’s Vancouver operations in 2010, as a Senior Mineralogist. While at SGS, she has developed extensive experience dealing with the management of process mineralogical projects using QEMSCAN, SEM, optical microscopy, EPMA and XRD analysis. With experience in dealing with global mining projects, she has worked on a wide range of deposits from base metals and iron ore to REE, U-Th and industrial minerals.
