Distribution of gold and some base metals in the Slana area, eastern Alaska Range, Alaska

Geology and mineral deposits of the Upper Chulitna district, Alaska

“…The conventional grams per 1,000 cc calculation, in genetic relation of these deposits with igneous rocks is suggested partly because of close spatial association and partly because similar rock series elsewhere have associated mineral deposits of similar mineralogic character. The association of auriferous rocks with diorites and quartz diorites along the trend of the Alaska Range is a well-documented one, as shown in the Juneau gold belt (Spencer, 1906), a t Valdez Creek (Ross, 1933b), and in the Slana area (Richter and Matson, 1968). The association of tin-bearing greisen with granite is worldwide.…”

Placer deposits of Alaska

“…Lode deposits associated with the zoned pluton contain galena and other sulfide minerals; several have been explored but have not been developed into mines. Gold is probably related to the diorite-quartz diorite complex (Richter and Matson, 1968). Total production from Grubstake and Slope Creeks probably was not more than 1,000 ounces.…”
