Reference information

Comments Magmatic ring structure with diameter about 15 km, includes widespread advanced argillic alteration (alunite). Cu-bearing tourmaline breccias are common. Area was explored by Czech-Mongolian expedition in 1980s and became an Ivanhoe prospect in 2002. Geochemisty of igneous rocks, including Sr/Y ratios, indicates an ""adakitic"" composition, favorable for porphyry Cu mineralization. 325.5 ±1 Ma, U-Pb (Blight and others, 2010); 321 ±9 Ma, Rb-Sr (Batkhishig and others, 2010). Alternate location (43.949812 N latitude and 107.643657 E longitude) is in the center of a region which appears to show wide trenching E, W, and S., and a drill pad SW of the point; also Singer and others (2008) approximately 27 km NW of point: 44.166667 N latitude and 107.5 E longitude.
