Chrysos Corp Ltd (C79)

Hi Debbie,

As a refresher, C79 has proprietary technology called PhotonAssay,  which Chrysos now exclusively commercialises. The technology leverages high-energy X-rays (photons) to induce nuclear excitation in mineral samples, enabling the fast and accurate analysis of gold, silver, copper, and other elements, typically within 2 minutes.  The units are generally deployed on mine sites, compared to traditional methods like fire (furnace) assay, which requires samples to be sent to a lab for testing, dramatically delaying the process. In short, what they have is a significantly faster, safer, more accurate, and more environmentally friendly alternative.

As you mentioned the CSIRO announced it has halved its stake in C79, selling ~10.8mn shares, leaving it with a 9% holding which it doesn’t intend to reduce further, at this stage, remaining committed to the business. We read nothing in their AGM to concern us around the business, and the stock has even received a number of upgrades this week.

• We continue to like C79 and believe the dip below $8 courtesy of the CSIRO selling is a buying opportunity which MM may take.
