Ausdrill technology secures international backing

Ausdrill subsidiary MinAnalytical has received accreditation to international standards for its PhotonAssay unit.

The technology, developed by CSIRO, slashes the time it takes to analyse a drilling sample from days to hours as an alternative to the traditional fire assay process.

The accreditation involved validating the technology through a series of tests, including benchmarking it against traditional fire assay mineral analysis.

As a result, the National Association of Testing Authorities (NATA) has issued accreditation in compliance with ISO/IEC 17025 – Testing. The validation took several months to complete.

“For our customers, it means the system has been validated and fully tested, and they can rest assured they will receive accurate results which have been benchmarked against fire assay,” said MinAnalytical general manager Gary Wheeler.

“With installation, commissioning and validation of the PhotonAssay unit now completed, we are able to offer this service to our customers.”

The first PhotonAssay machine was unveiled at MinAnalytical’s laboratory in Perth in May. MinAnalytical plans to commission two similar units in Kalgoorlie early next year.

The PhotonAssay instrument combines speed with a high degree of reliability. It represents a chemical-free approach to material analysis that gives accurate results in minutes. It uses a larger sample size than fire assay, with reduced sample preparation.

Chrysos Corp was formed in 2016 in partnership between CSIRO and RFC Ambrian for the purpose of commercialising the PhotonAssay technology.

Ausdrill has invested in Chrysos Corp and is assisting in commercialising the technology. MinAnalytical is the first company in the world to offer it to mining companies.
