Environments
Wildcatite is a new mineral first published in 2021. To date (November 2024) it has been recorded only from
the type locality.
Localities
At the type locality, the High Grade Hill prospect, Wildcat Project, Detroit Mining District, Juab County, Utah, USA,
wildcatite ranges from transparent orange to brown coatings or masses to earthy, white polycrystalline coatings
filling jasperoid fracture surfaces. Coatings of wildcatite are
generally less than 0.1 mm thick and may cover up to 5 cm2, while nanoscale crystallites of
wildcatite may form translucent red-brown “crystals” up to 0.1 mm. Wildcatite is found associated with
gold, calcite,
aragonite, native tellurium,
manganese oxides, iron oxides,
clinobisvanite, beyerite,
coronadite, paratellurite,
tellurite, andymcdonaldite, burckhardtite,
carlfriesite, eckhardite,
frankhawthorneite, khinite, mcalpineite, tlapallite and
xocolatlite
(CM 59.4.729–739).
