Content image: Kaiyuhite

Here is another odd mineral featured in Armin Scholer's current auction.

Kaiyuhite was first proposed as a new mineral back in the 1980s by young mining geologist Tony Dunn, who had noticed and collected this silver-grey metallic material whilst collecting at the Perseverance Mine, Kaiyuh District, in Alaska.

It appears that Tony was certain this was a new mineral type and specimens were circulated as "Kaiyuhite" but somehow never formally investigated, published or discredited as a new mineral.

It is not certain how this came about but Kaiyuhite is believed to be similar to/a form of baumhauerite, but again nothing appears to be published.

The locality itself appears to be slightly enigmatic too. It was a small lead-silver mine that operated short period in the early 1920s.

Tony Dunn (1958 - 1986)

Tony graduated in 1980 from New York State University having obtained a degree in Geology; from there he found work as a geologist based in Alaska. Sadly in 1986 he was killed in an accident: 

Daily Sitka Sentinel, Anchorage, Alaska: Tuesday, July 1, 1986:
"An employee of the Federal Bureau of Mines died after sliding 300 feet down a snow-filled chute on a mountain south of Juneau, officials said Monday. Anthony Dunn, 27, of Anchorage had been flown by helicopter to Hawthorne Peak as part of a surveying party looking at minerals, said Don Blasko, chief of the agency's Alaska field operations center. Saturday afternoon, Dunn was at the 3,000-foot level of the 4,200-foot peak when he apparently lost his footing and slid down the snow chute, Blasko said. At the bottom, Dunn crashed into rocks. He died at the scene and was taken by helicopter the 7 miles back to Juneau, said Alaska State Troopers spokesman Paul Edscorn."

Tony is remembered through the "Anthony P. (Tony) Dunn Award" established by the SUNY Geology Department, presented to a student that has shown a similar love of geology and scholarship to Tony.

Maybe it is because of Tony Dunn's tragic demise that the full research was never completed to fully understand the nature of "Kaiyuhite". 

Specimens of this mineral appear to date from the time of Tony Dunn and perhaps evoke the optimism of finding something new or maybe some unfinished business.
