|Location and accuracy||The locations of several placer prospect pits on and near Melozimoran Creek are uncertain. For this record, the site is located at the confluence of Melozimoran Creek with Little Melozitna River, in the SW1/4 of section 1, T. 9 N., R. 27 E., Kateel River Meridian.|
Melozimoran Creek has a meandering channel and low gradient. The rocks in the vicinity are Precambrian or Paleozoic, greenschist-grade micaceous quartzite and quartz-chlorite-muscovite schist and subordinate glaucophane-bearing schist, marble, and greenstone (Patton and others, 1977). The closest igneous body is the quartz monzonite and granite Melozitna pluton, whose northern contact is about 8 miles south of the confluence of Melozimoran Creek and Little Melozimoran River. Patton and others (1977) date the pluton as Early Cretaceous age on the basis of a K-Ar date of 111 +/- 3 Ma.Placer mining or prospecting on Melozimoran Creek is poorly documented. A few prospect pits were sunk between 1913 and 1918 near the mouth of the creek and some gold and cassiterite were recovered (Chapman and others, 1963).
