For over a century, Fire Assay™ has been the global standard for mineral testing. It is accurate, trusted, and deeply embedded in mining practice, but it is also slow, hazardous, and increasingly misaligned with the pace and sustainability goals of modern operations. The industry is now moving beyond this outdated method, and the shift is being accelerated by PhotonAssay™ from Chrysos Corporation—a system that delivers results faster, safer, and more efficiently.
What makes PhotonAssay™ stand out is not incremental improvement but fundamental change. Results are available in minutes rather than days, allowing for operational decisions to be made with unprecedented speed. The process uses no toxic chemicals, making it safer for both people and the environment. The technology also scales easily, handling large sample volumes and making it ideal for major mining projects. Beyond that, PhotonAssay™ provides real-time insights that enhance ore control and resource planning, enabling companies to operate with more precision and confidence.
For an industry under pressure to meet production targets while also advancing ESG commitments, these advantages are transformative. The alignment with Agile principles is striking: speed, adaptability, and continuous delivery of value. By eliminating bottlenecks in mineral testing, PhotonAssay empowers mining companies to respond to challenges more quickly, pivot more effectively, and deliver results that benefit stakeholders, communities, and the environment.
I recently had the opportunity to see the PhotonAssay™ system in action, thanks to Andrea McLaren and the Thunder Bay team at ALS Lab. Witnessing the process firsthand confirmed that this technology is not just a welcome upgrade—it is the future of mineral testing.
The mining sector is at a crossroads. Legacy methods, such as Fire Assay, still hold value, but technologies like PhotonAssay point to where the industry is headed: faster, safer, more sustainable, and better aligned with the modern demand for efficiency and accountability. The future of mineral testing isn’t on the horizon—it is already here.
This raises a larger question for all of us in the mining and mineral processing community: How do you envision technologies like PhotonAssay transforming the industry, and what barriers might still hinder its adoption?
