Appian Capital Advisory LLP, has acquired Trevali Mining’s 89.96% interest in the Rosh Pinah zinc mine, located in the Kharas region of southern Namibia. The underground zinc-lead mine is operational and it has a 2,000-metric-ton-per-day (mt/d) milling operation. Appian said it plans to restart the Rosh Pinah 2.0 mine expansion project which will nearly double the mine’s annual ore throughput to 1.3 million mt and improve safety and environmental performance.

“This acquisition marks a significant milestone for Appian as we continue to develop our world-class portfolio of highly attractive zinc assets, a critical metal that will help facilitate the upcoming energy transition,” said Michael W. Scherb, founder and CEO of Appian. “We look forward to welcoming the 450 employees at Rosh Pinah to Appian as we use our extensive operational and project development expertise to support the existing management team with delivering the Rosh Pinah 2.0 expansion project.”

The Rosh Pinah 2.0 expansion project includes the construction of new processing facilities, paste fill and water treatment plants, as well as a dedicated portal and decline to extended deposits. The project will increase mill throughput from 700,000 mt/y to 1.3 million mt/y of ore, increasing zinc equivalent production to 170 million lb/y, on average.

Following Vedra Metals in Italy and Pine Point in Canada, Rosh Pinah is Appian’s third acquisition in the zinc market. It has been in continuous operation since 1969, producing zinc and lead sulphide concentrates, as well as smaller amounts of copper, silver, and gold.
