@RogueTrader posted this Rask podcast on small caps which talked about XRF.

The one point I picked up was that the Seneca boys use the lab mining sample volumes from the big Labs SGS, ALQ, as a leading indicator for XRF consumable volumes and revenue.
Quite an interesting chart from the ALQ FY25 Annual Report of 27 May 2025 in terms of the noticeable sample volume spike in 2025 through to 16 May 2025, implying the flow through to XRF consumables volume.
