Location: This occurrence is on hill 1677 in the southern Kaiyuh Mountains, approximately 4.5 kilometers north-northeast of the top of Khotol Mountain. The location is accurate within 1.5 kilometers.
Geology: This occurrence is in garnet-quartz-chlorite-muscovite schist and consists of sparse gossan float, disseminated pyrite in the schist, and chalcopyrite in siliceous hornfels (skarn?). Six rock samples contained up to 1510 ppm copper, 85 ppm lead, 1.1 ppm silver, and 210 ppm arsenic (Flanigan, 1998). Flanigan 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). Also see NL012-014, 016, and 019-022.
Workings: This occurrence was discovered by Anaconda Minerals Company in 1980 or 1982 (Flanigan, 1998).
Age: 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).
Alteration: Hornfels and skarn (?) are present at this occurrence.
