Mimetite is a secondary mineral found in the oxidized zones of Lead deposits and is a member of the Apatite group. It’s a colorful mineral, typically yellow, yellow-orange, yellow-brown and less commonly green, with a sub-adamantine to resinous luster. It often occurs in association with Wulfenite, Calcite, Quartz, Barite, Cerussite, Malachite and Fluorite to name a few.
The crystal system for Mimetite is hexagonal, often forming barrel shaped hexagonal prisms and botryoidal, globular masses and crusts. Other forms include acicular and miniature spindle-shaped (spike-like) crystals.
Quality specimens of Mimetite are found in various locations, including China, England, Germany, Mexico, Namibia, Thailand and the USA (Arizona).
