Newmont Corporation, the world’s largest gold producer, announced on May 9, 2025, a strategic partnership with Australian-based Chrysos Corporation (ASX: C79) to deploy PhotonAssay technology across its global operations. The collaboration begins at the Ahafo gold mine in Ghana, marking a critical shift in how precious metals are analyzed and measured.
The partnership is formalized through a Master Services Agreement (MSA), with an initial renewable five-year term. The rollout underscores a broader industry movement toward digitization and environmental sustainability in core operational processes.
H2: What is PhotonAssay Technology?
PhotonAssay technology is a non-destructive, chemical-free assay method that uses high-energy X-rays to activate atomic nuclei in ore samples. These nuclei emit gamma rays, which are then analyzed to determine the precise concentration of elements such as gold, silver, and copper.
Unlike the traditional fire assay method—an industry standard for decades—PhotonAssay requires no hazardous chemicals and provides results in just two minutes, compared to the 24 to 48 hours typically needed for legacy techniques.
Chrysos CEO Dirk Treasure highlighted the deal’s importance:
“This agreement validates not only PhotonAssay’s operational efficiency but also its environmental integrity. We are proud to be partnering with the industry’s leading gold miner.”

H2: Key Deployment Details
- Initial Deployment Site: Ahafo mine, Ghana
- Timeline: Scheduled for H1 FY2026
- Payment Terms: Newmont will pay per sample, with minimum monthly commitments
The selection of Ghana’s Ahafo mine for the first deployment reflects Newmont’s confidence in the region’s operational capacity and strategic significance.
H2: Operational and Environmental Benefits
The PhotonAssay technology offers notable advantages:
- Speed: Real-time results (≈2 minutes)
- Safety: Eliminates need for acids and lead
- Accuracy: Capable of analyzing large sample sizes (up to 1 kg)
- Sustainability: To date, Chrysos reports 7,300 tonnes of CO₂ and 4,919 tonnes of hazardous waste eliminated from its global operations
These benefits support Newmont’s environmental, social, and governance (ESG) goals, especially as global regulators and investors intensify scrutiny over mining’s environmental impact.
H2: Market Impact and Investor Sentiment
Following the announcement, Chrysos Corporation’s stock surged, reflecting growing investor confidence in the scalability of PhotonAssay. Analysts suggest the backing of a tier-one miner like Newmont could fast-track industry-wide adoption.
Chrysos now has 58 PhotonAssay units contracted across Namibia, Western Australia, and Nevada, indicating robust global demand for its assay technology.
H2: Outlook for Mining Innovation
The integration of PhotonAssay technology marks a decisive step in the modernization of gold mining operations. As miners look to shorten assay turnaround times, increase worker safety, and reduce emissions, technologies like PhotonAssay are poised to become industry benchmarks.
This deal also reinforces Newmont’s strategy to maintain its global leadership through innovation-led sustainability. With the Ahafo deployment as a pilot, further rollouts are expected across Newmont’s portfolio, including operations in South America and North America.
