OceanaGold starts milling at Haile gold mine, South Carolina, USA

OceanaGold Corp has commenced milling at the Haile gold mine. Mick Wilkes, President and CEO: “We are very pleased with the start of milling ore at Haile. This milestone represents a special moment in the history of the Haile gold mine as this historic goldfield is re-established with a world-class modern mining operation in Lancaster county, South Carolina. From the start of the year, we established a firm timeline of key milestones that we have achieved throughout the year, culminating in the start of milling ore at year-end as planned. We have established a strong team in South Carolina that includes technical experts from across our business to carryout commissioning activities and transition to operations. Achieving this important benchmark in just 15 months since taking ownership of Haile is a true testament to the leadership and dedication of our team.”
