Large ore specimen loaded with mostly dull, silvery Rammelsburgite with lessor quantities of brass colored Nickeline with a rosey tinge and tarnished Algodonite. The fact is all three are a little hard to tell apart and this would be a good study specimen with a SEM or a polished section. One side is cut and is likely has been well identified by polished section. Old David Garske label from Rapid City. One side as Annabergite alterations with bead like crystals a clear indication of the nickel content. There are also some bright red alterations (?), which is possibly Pyrargyrite but doesn't seem likely.
