What Our Clients Say...

Simple sample preparation, fast turnaround times for high-quality results and improved outcomes related to health, environment and the community.

Wess Edgar, Chief Geologist for Kirkland Land Gold in Australia

PhotonAssayᵀᴹ provides a significant advantage where large assay charge sizes are required, particularly in coarse gold mineralisation.

Dr Simon Dominy, Principal Advisor, Novo Resources Corporation

PhotonAssay's simple process reduces waste, involves fewer people, requires less technical training and reduces the likelihood of error

Stuart Thompson, CEO, MSALABS

This award-winning technology is capable of rapidly and accurately scanning up to 500g of material at a time, an important capability when dealing with coarse gold systems.

Novo Resources Corporation, Operational Update October 2020

PhotonAssayᵀᴹ yields efficiencies around simple sample preparation and fast turn-around times. Additionally, as a non-destructive methodology, it allows samples to be used for other post-assay analyses such as environmental or metallurgical testing.

Dr Simon Dominy, Principal Advisor, Novo Resources Corporation

Check-assays using the larger PhotonAssayᵀᴹ method identified the existence of coarse gold, highlighting the need for larger assay sample sizes to be representative.

Chris Cairns, Executive Chairman, Stavely Minerals

Chrysos PhotonAssay™ provides timely quantitative data,
drives optimisation through the value chain, and delivers
the operational outcomes that matter to miners.
