specimen number:
2063114

location:
Endeavor Mine, Cobar, Robinson Co., New South Wales, Australia

description:
Collected in the 1980s, a long loose branching grouping of twinned native silver crystals. No points of attachment, this is a floater and in good condition. The specimen comes with a previous label from the collection of Ray DeMark.

The Endeavor Mine, originally known as the Elura Mine, is located north of Cobar in Robinson County, New South Wales, Australia. Geologically, the deposit is a massive sulfide system hosted within Lower Devonian sedimentary rocks, featuring complex structural lenses rich in zinc, lead, and silver. Discovered in 1973 and entering production in the 1980s, the mine underwent extensive underground operations targeting its rich polymetallic ores. Of particular note to mineral collectors and mining history, the supergene oxidation zone of the deposit yielded exceptional specimens of native silver, which crystallized as striking wire and dendritic formations within dissolved cavities and pockets of the ore body.
