Specialist Geochemical Laboratory
LABORATORY
EGi's laboratory is a recognised leader in AMD testing, utilising proprietary methods and techniques developed in-house. We run our own in-house laboratory, conducting the full range of acid-base accounting, NAG, leach, and kinetic tests to test mine materials for acid generation, metal leaching, salinity, and toxicity. We tailor testing programs to each client's specific needs, ensuring high-quality results that inform effective management strategies.
Here are some of the key reasons to work with EGi.

Here are some of the key reasons to work with EGi.
01 We run our own in-house laboratory, so our consultants talk directly to the
people doing the testing and can better interpret the results.
02 We tailor testing programs to each client’s specific needs.
03 We deliver the highest level of quality with certified reference materials we
developed ourselves.

We have complete control over laboratory testing – we don't need to rely on or second guess how external laboratory testing has been conducted. Our laboratory works only on EGi projects and reports are delivered by the same people who designed the test program. A number only becomes meaningful when it is read in the context of the method that produced it and the material it came from. In addition, the people who run our tests sit on the same team as the geochemists advising on your site, so context travels with the result instead of being lost at handover.

Our site-specific approach
Our site-specific approach
We design your test program around your mining operation before any sample reaches the laboratory bench. We review the deposit geology, material types and existing data, then select samples that genuinely represent the mine envelope. You receive results assessed against your site context, so that your operations can act on clear materials-management and segregation guidance.

Because we run our own laboratory, we can offer clients laboratory test programs that cover occasions when the standard test suite doesn’t provide all the answers. For example, there may be a sitespecific problem you want to investigate. Our team can design a lab test program that fits the purpose, then carry it out, providing results that support your needs and answer your questions.

Certified reference materials
Certified reference materials (CRM), samples carrying an independently guaranteed value, are used to run alongside client samples to confirm a test is performing correctly. Until recently, CRMs available for ARD testing were limited to just a few. EGi worked with Flinders University and Geostats, a global supplier of reference materials to the mining industry, to create ARD-specific CRMs and now uses them in routine test work.

To classify acid-forming potential, EGi uses net acid-producing potential and net acid generation (NAG) test results as initial screening tools. Using both independent measures significantly reduces the risk of prediction errors and better defines the ARD characteristics of samples.
Additional specialised static tests help resolve uncertainties in classification. Kinetic test procedures, such as leach columns, involve multiple measurements over time and are used to assess a range of ARD/NMD issues, including sulphide reactivity, oxidation kinetics, metal solubility, and the leaching behaviour of test materials.
Following are the main tests that we run.
