“Rottenstone” is the original description by local First Nations of a 30-foot (9.1 metre) outcrop on the southeast shore of Rottenstone Lake, approximately 130 kilometres northeast of La Ronge, SK.  First Nation members brought this outcrop to the attention of traders, and the area was later staked as the Hall showing.  The Hall showing later became the Hall deposit and eventually the Rottenstone Mine, which operated from 1965 through 1969.  The deposit was mined by open pit and 28,724 tons were recovered, averaging 3.28% Nickel, 1.83% Copper, 4.70 g/t Platinum, 3.90 g/t Palladium, and 1.03 g/t Gold (9.63 g/t Platinum, Palladium +Gold (Fraser, 2000).  The area comprising the Rottenstone Mine is currently held by Fathom Nickel.
