Reference information

Comments Grab samples to 0.98% Cu and 5.5 g/t Au. Copper oxide mineralization in altered volcanic tuff and siltstone; strike length of 1.5 km. Drilling in 2005. Location is about 30 km or more NW of the Asia Gold and BHP Billiton JV property, according to Peréz (2007). Mineral site location possibly incorrect. This location is 0.5 km from Zargyn Khar Ovoo which is included in Dejidmaa and others (2002) as MRAM #18 and Nokleberg and others (1999). Zargyn Khar Ovoo is variably referred to a porphyry Cu (Dejidmaa and others, 2002) and replacement Cu (Nokleberg and others (1999).
