the deposit was discovered in 2003 and eventually became a small operation producing precious metals-rich copper-nickel ore that was concentratedrefined by a custom millsmelter. In its short lifetime, the broken hammer mine produced some excellent sperrylite crystals, first from a bulk test-mining of ore and then from a 1.5 year production span.the silver ore slices are really outstanding examples of what a rich silver ore vein looks like, right out of the mine. the ore has been sliced into to slabs, which makes it possible to see shiny patches of dendritic silver growing into cobaltite and other silver arsenide minerals
cobaltite is a sulfosalt mineral, containing sulfur, arsenic, and cobalt. It was discovered as early as 1832 from mines in the cobalt district, ontario, canada. the mineral was named after the german word kobold, which means underground spirit or goblin, representing its elemental composition. properties of cobaltiteand labrar mineral zones exploration samples from primary mineral ore rocksg. these from mineral piles, small mine workings as well as from outcrops, indicate cobalt concentrations between 0,001% and 1,95%, together with variable contents for
feb 22, 2010 On earth vein ores rich in copper, zinc, lead and gold are found in the sudbury impact structure in canada. other impact-related ores in the united states and for mining to be profitable, high quality ore needs to be found in a small area. mining exploration is the term we use for finding out where the valuable minerals are. today technology helps mining geologists and surveyors to find high quality ore without having to do any digging.
placers are valuable minerals found in stream gravels.californias nickname, the golden state, can be traced back to the discovery of placer deposits of gold in 1848. the gold weathered out of hard metamorphic rock in the western sierra nevada, which also contains deposits of copper, lead, zinc, silver, chromite, and other valuable minerals.sep 30, 2016 scrutiny is heightened for a few of these minerals. 2010 u.s. law requires american companies to attempt to verify that any tin, tungsten, tantalum and gold they use is obtained from mines
