Getchellite is a rare arsenic-antimony sulphide whose type locality at Getchell mine, lies less than 1 km to the west of Twin Creeks mine where this specimen is from. Fine, blood red Getchellite crystals occur with areas of more massive, mustard yellow Orpiment over a matrix of dark silver Stibnite. Getchellite commonly occurs as a powdery deep red coating on matrix, so to have such a well crystallised example is exceptional. The Twin Creeks mine is in the Potosi Mining District of the Osgood Mountains in Humboldt County, Nevada, USA and exploited a remarkably diverse polymetallic deposit containing Au-Ag-As-W-Sb-Hg-Ba-Mo-F-Tl-Te-Bi-Sn-Pb-Zn-Cu. This richly crystallised specimen is mounted on a small, clear acrylic base.\n
