Hog Heaven, Montana
Located on private land approximately 50 miles south-southwest of the town of Kalispell, Montana.
Historical high-grade silver and gold production by Anaconda.
Typhoon™ deployed to advance the search for additional epithermal mineralization and deep porphyry source.
Large district, underexplored at depth, with substantial alteration footprint and multiple mineralized centers.
SUMMARY
The Hog Heaven district consists of several high sulfidation epithermal mineral deposits and prospects as well as several now-closed mines, including the Flathead Mine. The ongoing drill program is designed to search for: additional silver, gold, and copper-rich high sulfidation epithermal mineralization, which was the focus of historical mining activities, and porphyry copper mineralization located at depth.

History
The Flathead Mine was mined by Anaconda Mining Inc. from 1929 to 1946, producing approximately 241,000 short tons of direct-ship ore averaging 26.6 troy oz/ton silver. Another operator mined the Flathead Mine from 1963 to 1975 producing 49,700 short tons averaging 9.35 troy oz/ton silver. Other previously mined high sulfidation epithermal mineral deposits within the bounds of the Hog Heaven Project include the Ole Hill and West Flathead Mines located 1 mile west of the Flathead Mine; the Margarite Mine, south of Flathead Mine; and the Martin Mine just northwest of Margarite Mine. Ivanhoe Electric’s exploration team believes that the Flathead Mine is part of a much larger mineralized system that has remained unrecognized by past miners and explorers.
