An excellent, rich specimen of Uraninite var. Pitchblende with colorful yellow-orange “Gummite”group minerals from the Aubrey Ladwig Lease, Golden Gate Canyon, Golden, Colorado USA. Good large specimens from this Colorado locality are VERY rarely seen, and this is one of the best examples I’ve personally seen from there. Measures ~170,000 CPM on my Ludlum Model 3 counter with the 44-9 probe. From the noted collection of Jack Nieburger. A rare classic!
