Assay Lab

Based in Ballarat, Australia, Gekko’s Assay Laboratory is a world-class facility.

This laboratory service stems from a foundation in developing gravity separation and intensive leach technologies for maximising gold recoveries.

Gekko’s Assay Lab operates to the highest occupational health and safety standards, and quality control. Standard operating procedures are in place for all in-house systems and processes. The Assay Laboratory also provides technical support for Gekko’s Metallurgical Laboratory.

A world-class facility that provides quality and timely analyses.


Time is money in mining and that’s why rapid accurate results help to keep a mine running productively.

Reliable technical results provide certainty in mining operations and ensure sound decisions are made based on laboratory test evidence.

Gekko’s team of process and chemical engineers, metallurgists and technical specialists are dedicated to providing high-quality results, fantastic customer support and helpful advice.

Gekko’s assay instruments meet strict quality control guidelines and all test runs include internationally certified reference standards to ensure an excellent standard of mineral testing is provided.

The Assay Lab is fully equipped with state-of-the-art instruments for sample preparation and analysis to deliver useful, accurate results.

Gekko understand the importance of testing mineral recoveries and improving operational processes for greater efficiency and more profits.

Experts in Coarse Nuggety Gold

Gekko specialise in determining the quantity of gold in coarse nuggety ores. Accurate quantisation and characterisation of these ores is essential.

Gold quantities will indicate whether mining the ore deposit is economically viable.

Specific ore characteristics will pinpoint what process steps will be beneficial to recover the most gold from the deposit.

Gekko also specialise in base metals such as Ag, Cu, Fe, Pb, Ni, S, Zn, Co, Sb, Mn and Mg in ore.
