Clear Creek Unknown Number 10 (CCUK-10) has been identified. It is named gaildunningite, after Gail Dunning of Sunnyvale, CA. CCUK-10 needs to be retired or cross-referenced to gaildunningite.

See Cooper et al., 2019, GAILDUNNINGITE, IDEALLY Hg3[NHg2]18(Cl,I)24, A NEW MINERAL FROM THE CLEAR CREEK MINE, SAN BENITO COUNTY, CALIFORNIA, USA: DESCRIPTION AND CRYSTAL STRUCTURE, "The Canadian Mineralogist," Vol. 57, pp. 295-310, DOI: 10.3749/canmin.1800080.

The new mineral is named after Mr. Gail E. Dunning (born 1937) of Sunnyvale, California, who recognized the mineral in 1993 at the Clear Creek mercury mine, San Benito County, California, USA. Mr. Dunning, now a retired metallurgical engineer formerly with General Electric Company, has been an avid collector of rare minerals since 1957, specializing in barium-silicate and mercury-bearing minerals. To date, he has discovered over 20 new or potentially new minerals which are currently under study. He has authored or co-authored 48 papers relating to new mineral descriptions and mineralization of California and Nevada mines.

Done. Thanks for the reminder, Michael.

High time that a mercury mineral was named after Gail! I can't think of anyone who has spent more time studying Hg minerals.
