"Gekko Systems operates on the basis of working with customers to assess the best possible technical outcomes for their projects.  We explore with the customer the characteristics of the ore, the potential recoveries and the economic benefit that our technology can deliver.

From the outset we are working towards developing the best technical options for the specific circumstances of projects, to maximise the economic and environmental outcomes.  For a greenfield operation our predictive laboratory procedures enable the customer to optimise the selection of equipment for a location's ore characteristics.

We have the capacity to audit the mill of existing operations and advise clients on process improvement and how Gekko's equipment range can be tailored to each project's specific needs.  From here Gekko provides a full engineering package to implement these decisions, working closely with the customer to ensure the project's expectations are met."
