While we don't focus on modelling or day-to-day operations directly, our network covers these areas, and we offer support to ensure seamless implementation and ongoing success.
When should you engage us? As soon as you realise you are facing a challenge, either in the design of a flowsheet for your particular orebody, or for retrofitting a new technology into an existing operation, or when facing the mountain that is the drive to decarbonise your operations, or for helping your operation achieve nameplate capacity or efficiency.
We can move mountains, but we prefer to do it early on as profitability and positive cash flow resumption is key to sustainability.
