1.35" Red-Orange Pyromorphite Formation - Bunker Hill Mine, Idaho

Bunker Hill Mine is a combination of several properties that were mined primarily for lead, producing zinc and silver as a by-product. Mining began around 1885 and continued for over 95 years. During this time, the mine yielded 165 million ounces of silver, 3.6 million tons of lead and 1.4 million tons of zinc. Following its closure in 1988, the area became a Superfund site due to lead contamination.

During the years that the Bunker Hill Mine was active, it produced some incredible mineral specimens that became highly sought after by mineral collectors. These minerals include but are not limited to native silver, cerussite, anglesite, and stunning pyromorphite clusters.

About Pyromorphite

Pyromorphite is a vibrant, often green-colored lead-based mineral known for its striking crystal formations. Belonging to the apatite group, it typically forms in hexagonal or prismatic crystals with a resinous to waxy luster. Colors can vary from green to yellow, orange, and brown, influenced by its chemical composition. Pyromorphite is commonly found in the oxidation zones of lead ore deposits, where it crystallizes into stunning clusters or "botryoidal" (grape-like) structures. Collectors prize pyromorphite for its vivid hues, distinctive crystal shapes, and rarity, as it's typically found only in a few locations worldwide.

Safety: The lead in pyromorphite can be harmful if absorbed into the bloodstream by inhalation or ingestion. The crystals won't pose a health hazard just sitting on a shelf, but we recommend washing your hands after handling.
