Mining operation

At the Hishikari Mine, we engage in mining operation. In mine mining operations, the bedrock strength, mineral vein direction, and ore quality differ with each tunnel. However, with the technology and know-how we have cultivated up to now, we are able to contribute to safe and stable mine development.
