TXZ83XXX: The finding of carlhintzeites in Dachang, produced at the beginning of 2025, constitutes an unexpected mineralogical event in a district traditionally known for its stibnite mineralization. Until then, Carlhintzeite had only been documented in the form of very small crystal aggregates or poorly differentiated masses, without defined macroscopic specimens. The appearance of crystals of good size therefore represents a relevant advance in the knowledge of this very rare species.

In this specimen, the Carlhintzeite, of intense yellow color, is very rich in translucent crystals and occurs on limonite’s matrix. It has been published on the website of the prestigious journal Mineralogical Record, in its “What’s New” section by Tom Moore: Tom’s Online Report #75 – 12/09/2025
