Geology, Alteration, and Mineralization of the Sugar Gold Prospect, Yukon Territory, Canada
The Sugar gold prospect, located 20 km southeast of the Coffee gold deposits and 10 km northwest of the Casino Cu-Au-Mo deposit in the Yukon Territory, is hosted in the mid- Cretaceous Dawson Range batholith. Sugar forms a part of a belt of gold mineralization within the Dawson Range and as such a s...

The Sugar gold prospect, located 20 km southeast of the Coffee gold deposits and 10 km northwest of the Casino Cu-Au-Mo deposit in the Yukon Territory, is hosted in the mid- Cretaceous Dawson Range batholith. Sugar forms a part of a belt of gold mineralization within the Dawson Range and as such a study of its lithology, alteration, and mineralization offers important information for metallogeny in the Yukon, Canada. Three mappable sub-units are recognized in the field area: a biotite hornblende quartz monzodiorite; a K-feldspar phyric hornblende biotite syenogranite; and a biotite hornblende diorite. These plutonic rocks bearing continental-arc geochemical signatures are cut by steep, west to northwest-striking andesite dikes of unknown age which themselves bear continental-arc geochemical signatures.
