Brine Resources

JORC and NI 43-101 estimates of economic brine resources for planning and development


Unlike traditional mineral resources that occur as solid deposits, mineral-enriched brine resources reside within porous- and fractured-rock aquifers. Estimating the mineral resources and reserves in a brine deposit presents technical challenges; this process requires understanding not only the spatial and temporal variability of brine densities and concentrations but also the variability of flow characteristics in the host aquifer. Since 2009, M&A has helped clients develop sound mining plans by exploring, characterizing, quantifying, and developing their mineral reserves.


  • Conducting field and modeling investigations to define drainable resources and economically extractable reserves
  • Developing variable-density groundwater flow models to predict how mineral concentrations change with pumping
  • Designing wellfields, trenches, and extraction systems
  • Predicting sustainable production rates
  • Assessing freshwater resources required for mineral processing
  • Providing expert review and assessment of technical reports and site conditions
  • Preparing technical reports by Qualified Persons in compliance with Canadian National Instrument (NI) 43-101 and Australasian Joint Ore Reserves Committee (JORC) requirements
