:: Step into the Future with Keyhole Processing

The management and staff of Gekko are delighted to present the company’s latest innovation - the Python Underground Processing Plant (Python UPP). This high-tech, fully automated modular plant is the outcome of five years of intensive research. The unit has been designed to operate in a 5m x 5m tunnel and produce a high-grade concentrate that can be pumped to the surface.

“We believe that mining companies will save up to 15-25% of their total costs. Experience curve benefits will result in even higher returns”, noted Gekko’s Technical Director, Sandy Gray. “Step change savings can be expected in haulage, ventilation, back fill, grinding, staffing, tailings disposal and environmental costs. Installation of the unit may also de-bottleneck production and it has the potential to lower cut off grade.

The process design concept is to operate the crushing, grinding and pre-concentration plant underground and to pump the concentrate to the surface. Depending on available voidage underground, and metallurgical test work, it can be expected that a volume concentrate of between 5-30% mass will be pumped to the surface - eliminating the need for trucking.

Gekko’s 20 t/hr prototype Underground Processing Plant has recently passed its most crucial step after undertaking onsite trials to evaluate capacity and quality control. The plant took less than 24 hours to commission.
