General Notes
Mckinstryite from Tsumeb was reported by Joy Désor in 2020, identified by SEM-EDS and Raman, and apparently associated with iodargyrite, silver and an unknown AgHg phase (possibly eugenite). Standardless EDS analysis was consistent with confirmed mckinstryite from the Clara mine in Germany. No further details were provided.

Questionable status is retained for mckinstryite pending further information.
Associated Minerals
iodargyrite (?); silver (?); eugenite (?)
