Location and accuracy The Aladdin prospect is in the southern Kaiyuh Mountains, on a ridge approximately 1 mile east of VABM Kluklaklatna. For this record, the site is plotted in the southwest corner of sec. 33, T. 14 S., R. 5 E., Kateel River Meridian. The location is accurate within 2 miles.

Geologic setting

Geologic description

The Aladdin prospect consists of quartz-arsenopyrite-scorodite veins up to 0.2 meter thick, and of breccia comprising centimeter-scale, rounded fragments of massive arsenopyrite in a siliceous matrix. The deposit is associated with biotite granite of the Khotol Pluton and with quartz-muscovite-chlorite schist; the mineralization is exposed in a 4- by 7- meter frost boil in the schist. The deposit is similar to the one at the nearby Honker prospect (NL018) (Flanigan, 1998).
Eight grab samples contained up to 755 ppm copper, 430 ppm lead, 11 ppm zinc, 19.66% arsenic, 8.5 ppm silver, and 1285 ppb gold (Flanigan, 1998). The discovery samples also contained up to 185 ppm tin (M. Millholland, written communication, 2001).
Flanigan (1998) interprets the Aladdin deposit to be related to magmatic fluids from the Khotol pluton, based on its proximity to the pluton and its low molybdenum content . K-Ar and Ar/Ar dates for the Khotol pluton are approximately 110 Ma (Flanigan, 1998).
