Location: This placer mine is at an elevation of approximately 150 feet in Lemon Creek 1/4 mile upstream from its junction with Sawmill Creek. It is mainly in the NE1/4 section 26, T. 40 S., R. 66 E. of the Copper River Meridian. The location is accurate.
Geology: There are 2 large gravel basins in Lemon Creek, both were worked for placer gold in the late 1880's and early 1900's (Redman and others, 1989). The upper basin was the location of the Glacier placer (JU124) and the lower basin was the location of the Lemon Creek placer. The gravels in the lower Lemon Creek basin are 100 to 500 feet wide and 8 to 10 feet thick. The gravels lie on glacial clay in a bedrock-dammed basin (Redman and others, 1989). Gold was recovered from this placer but the amount is unknown. U.S. Bureau of Mines samples at the lower Lemon Creek placer contained 0.016 ounce of gold per cubic yard (Redman and others, 1989).
Age: Quaternary.
Production: Gold was recovered from this placer but the amount is unknown.
