Smaller specimen but packed with excellent Calaverite crystals partially covered by an alteration. This mine is not reported to have tellurides at least on Mindat. It came out of the collection of Delbert Brown, a deceased geologist who was located in Custer, SD. Delbert spent a lot of time in Colorado collecing at some of the old mines. A typed label has "Mogul" of the Prince Albert mine. The research I have done did not uncover this exact locality, however there is a Prince Albert mine. Raman verified as Calaverite.

Several brassy goldish fragmented grains of Calaverite to 5mm occur on this specimen on one side with a coating of chalcedony or hyalite Quartz. On the flip side purple flourite as fine disseminations occur. On both sides occur a little silvery dark grey metallic crystal grains of probably Petzite. It is brittle. There is perhaps light blue Celestine. All these minerals are mentioned and described in the ore deposits section of the USGS Paper 223 titled "Geology and Ore Deposits of the Front Range, Colorado" by the Lovering & Goddard.
The Ajax mine fell within the group of independent mines later grouped within the Granite mine north of the town of Victor. The mine is bounded by the Portland and Strong mines. These mines fall with a volcanic crater which was later mineralized in three episodes. The matrix is a vuggy fine-grained and siliceous with disseminated and formless Pyrite.

Goldish yellow to silvery crystal plates of Calaverite from 5-8mm exposed along a quartz vein of intrusive-volcanic rock. A good rich specimen with six spots showing nice, lamellar/platy crystals of brittle Calaverite. The Indendence mine, north of Victor, is located on the southeast edge of Newmont's open pit Cripple Creek mine.
Robert Waidler purchased the specimen from the mineralman.com. On that tag it is noted that the specimen originated from the George A. Koening and Seaman collections.
