:: Gekko Expands Service Capability with Acquisition of Assay Laboratory

Gekko Systems is delighted to announce the opening of the company’s Assay Laboratory located in Ballarat. The assets were purchased by Gekko from Balmaine Gold Pty Ltd, a subsidiary of Castlemaine Goldfields Ltd (ASX: CGT). Originally established by Lihir Gold, the laboratory is dedicated to the analysis of drill samples and metallurgical samples.

“The acquisition of the Gekko Assay Laboratory is a natural progression for Gekko Systems” said Elizabeth Lewis-Gray, Gekko’s Managing Director. “Its operation will complement our extensive and world-class metallurgical laboratory which has a strong focus on feed preparation, pre-concentration and gravity concentration of gold ores and concentrate treatment. The Assay Laboratory will accelerate turnaround and provide a broader range of in-house services to our local and interstate customer base."


Lewis-Gray added “The modern facility is impressive and includes a range of state-of-the-art equipment including AAS, fire assay, screen fire assay and environmental solution analysis equipment. New ICP and Leco analysers have also been acquired and are currently being installed to allow the determination of both gold and base metal elements from samples. This will widen the capabilities of the laboratory from a purely gold focus, to gold and base metal elements”.

Gekko Directors and staff inspect the Assay Laboratory facilities. From L-R: Sandy Gray (Technical Director), Vince de Santis (Director), Ken Donaldson (Group Services Manager), Shaun Marrow (Assay Laboratory Manager), Dale Elphinstone (Director), Elizabeth Lewis-Gray (Managing Director).


The Gekko Assay Laboratory is targeting South-East Australian mining operations and offers speciality skills and capacity in:

  • Gold analysis
    • Sample preparation
    • LeachWell 500-3000 for coarse gold
    • Screen fire assays
    • Fire assays
  • Geochemical and metallurgical analysis
  • Environmental analysis

The laboratory offers customers many benefits, with a particular focus on fast turn-around, flexibility and accuracy of results. In order to achieve customer requirements the operation is willing and capable to negotiate sample turnaround schedules to meet the needs of each site.

Laboratory Manager, Shaun Marrow, is a Senior Chemist and operated the facility for Lihir Gold prior to the acquisition. Shaun is an extremely experienced operator and has already developed strict quality control procedures. These have been audited by IMO and cover processes such as bulk leaches, fire assay, AAS and WAD Cyanide analysis.

Customers already utilising this quality facility include Castlemaine Goldfields, University of Ballarat, Gekko Metallurgical Laboratory and Morning Star Gold N.L.
