The Gold Mine is a 1,900 seat multi-purpose arena in Long Beach, California, on the campus of California State University, Long Beach. Opened in the late 1950s, when it was known as University Gym, the Gold Mine was home to Long Beach State's basketball and volleyball teams until the Walter Pyramid opened in 1994. It used to have nearly 2400 seats in wooden bleachers before a mid-80's renovation. 
The Gold Mine is still used occasionally for volleyball and basketball games, if there is a scheduling conflict at the Pyramid. Today, its primary function is for Long Beach State intramural sports and other campus events.
