Pugh Quarry was opened to produce limestone, but collectors remember it for the crystal-lined cavities hidden within that rock. Its golden-brown dogtooth calcites became classics of Ohio mineral collecting, preserving the history of mineral-rich fluids that moved through Devonian carbonate beds long after they formed.
Apatite from the Yates Mine is more than a green crystal from a noted Canadian locality. Research into these prisms revealed tiny mineral-filled inclusions that preserve evidence of the extraordinary melt in which they grew nearly one billion years ago. This specimen from the Donald Wininger Collection connects a twentieth-century uranium prospect with one of the most intriguing geological stories in the Grenville Province.
Most collectors picture celestite as pale blue crystals from famous localities around the world. Then they encounter a specimen from Forks of the Credit, Caledon Township, Ontario, and everything they thought they knew changes. This uncommon Canadian occurrence produced beautiful orange celestite that remains one of Ontario’s classic collector minerals. Preserved in the Donald Wininger Collection, this specimen reminds us that sometimes the rarest treasures are found where few people expect them.
Most metals remain chemically locked inside minerals and must be separated through crushing, heating or smelting. At Cobalt, Ontario, nature sometimes completed that work underground. Silver emerged from mineral-rich fluids as nearly pure metal, filling narrow fractures, threading through calcite and growing into leaves, branches and delicate wires. Specimens preserved in the Donald Wininger Collection reveal why this legendary Canadian mining district remains one of the most important native-silver localities in the world.
