The combination is what makes this piece appealing: the dense, submetallic black of the uraninite stands out sharply against the dark green pyroxene host, and the crystals are well defined within the matrix.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eBicroft was a significant producer during the uranium boom of the 1950s and early 1960s, and its ore came from pegmatitic and skarn-type rock where uraninite occurs alongside pyroxene and other accessory minerals. Uraninite crystallized in its host rock, rather than loose or as isolated grains, shows the species in its original geological context, and specimens from named Bancroft mines with documented provenance are increasingly hard to find now that the district is long closed.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eA great addition to a Canadian uranium suite, a collection of Bancroft-area classics, or a display showing mineral associations from the Grenville Province.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eex.
