MYSTERY PHOTO: Can Anyone Identify This Mine?

We need help in identifying this mining location. We believe its Shasta County, but it could also be out of the area. This is a mystery photo from our Society's archives. We know the photographer is Chester Mullen. Where is this place? Perhaps you hold the answer to the mystery? There are buildings on a flat surface of a tailings pile here. Feel free to comment, like, share, call and or e-mail us at Shasta Historical Society.
