Sumitomo Metal Mining’s Hishikari gold mine in Japan automates with Sandvik

Sumitomo Metal Mining Co Ltd’s Hishikari mine is the first Japanese underground mine utilising automated loading technology from Sandvik. Sandvik says AutoMine® will help enable increased productivity, improved safety and better cost control, while bringing digital transformation of the mining process closer and increasing operational transparency.

The Hishikari mine, located in northern Kagoshima Prefecture, boasts a high grade of around 20 grams of gold per tonne of ore and has been producing gold steadily since 1985. Hishikari is the only gold mine in Japan that still operates on a commercial scale today. The mine, which commissioned AutoMine® Lite on a Toro LH307 underground loader in December 2022 to operate in its small cross-section tunnels, will utilise the system in production areas to enhance safety, accelerate underground efficiency and improve productivity.

2Sandvik did a great job commissioning and training our engineers and operators on the AutoMine® system,” said Hidenobu Yabu, Manager of Mining Section for the Hishikari mine. “Our goal is to become a corporate enterprise that produces resources with advanced technology by 2030. By implementing advanced technology and innovation, we aim to reduce costs, increase productivity and improve safety. Our commitment to sustainability is reflected in our long-term focus on the Hishikari mine.”

“We are excited to partner with the Hishikari mine on this project and look forward to contributing to the operation’s sustainability and productivity,” said Jan-Douwe Wansink, Business Line Manager Automation for Sales Area Southeast Asia at Sandvik Mining and Rock Solutions. “AutoMine® provides a safe, controlled environment that boosts productivity and profitability while helping to protect operators and other mine personnel in underground operations. This is an exciting opportunity for the Hishikari Mine and Sandvik.”
