The Sons of Gwalia Mine is a historic gold mine located in Leonora, Western Australia. It was first established in 1896 and became one of the richest gold mines in the region, contributing significantly to the local economy. The mine operated for over a century, producing thousands of ounces of gold. In 2004, the mine was closed due to declining gold prices but was later reopened in 2015 by St Barbara Limited. Today, the Sons of Gwalia Mine continues to be an important site for gold extraction and plays a vital role in the mining industry of Western Australia.
