Medium-scale W-Mo-Be skarn with a high Rb content, owing to the presence of rubidian lepidolite. The deposit consists of 71 small lensoid orebodies that strike in EW orientation and dip at 50Β° to 65Β°. The largest body is 700 m long, extends 300 to 500 m downdip and ranges from 80 to 150 m wide. The bodies occur predominately in contact-metamorphosed tuffaceous sandstone, and andesite in the exocontact zone and partly in the granite intrusion. The ores occur in veinlets and as disseminations. Due to difficulties with ore dressing, the deposit is presently not mined.
