:: GLR Orders Goldfields Plant

GLR and Gekko Systems are pleased to announce that GLR has placed an order for a complete 2,000 tpd Gekko modular plant for its Goldfields Project located in Northern Saskatchewan.

The Gekko designed gravity recovery and intensive leach plant will be the first of its kind to be used in Canada. The sale adds to Gekko Systems' growing global reputation as a developer of innovative cost-saving technologies that also significantly increase mineral recovery rates. Gekko Systems has recorded a 307 per cent growth rate over the past three years and was recently rated as Australia's 20th fastest-growing technology company.

Gekko has carried out extensive testing on Goldfields ore grading from over 60g/t to less than 1g/t with excellent results.

The test work results revealed that:

  • The ore tested is highly amendable to treatment by gravity concentration. The combination of primary jigging, centrifugal scavenging and cleaning should result in a gravity concentrate containing 85% of the gold in about 4-5% of the mass.
  • The concentrates tested were highly amendable to intensive cyanidation. Leach recoveries of 98-99% are expected.
  • Cyanide destruction using hydrogen peroxide is an effective method for the Goldfields project.

The Gekko recommended flowsheet provides for very low capital and operating costs when compared with traditional whole ore cyanidation processes and will have very little environmental impact.
