Description

Species: Uraninite var. Pitchblende, Chalcocite

Locality: Mi Vida Mine (?), Lisbon Valley Mining District, San Juan County, Utah, USA

Dimensions: 7.4 x 3.7 x 3.8 cm.

Very rich specimen of waxy black pitchblende with minor chalcocite from the Moab area of Utah (possibly the Mi Vida mine). This is material collected 50+ years ago by famous northwest USA mineralogist Bart Cannon. Specimens of this material that are this rich are quite tough to find these days! Measures ~100,000 CPM on my Ludlum Model 3 Counter with the 44-9 probe. Rare!
