The Rothsay gold mine is situated within the Warriedar Greenstone gold belt of the Yalgoo Goldfield in the southern Murchison region, approximately 300km northeast of Perth.
The current project plan extracts mineralised ore from narrow sub vertical structures. The scope of Redpath's contract includes portal and decline development, and is due to commence in the September 2020 quarter.
Gavin Ramage, managing director of Redpath, said: "We are looking forward to working with the Silver Lake Resources team in increasing value for their shareholders through safe and efficient delivery of underground mining services."
