Rosh Pinah Zinc’s new paste fill plant unlocks growth potential 

Rosh Pinah Zinc (RPZ) and Appian Capital Advisory Limited, an investment advisor, recently announced the commissioning of a new paste fill plant, a critical component of the RP2.0 expansion project, which is over 85% complete, on schedule, and within budget. 

The paste fill plant is the first commissioned paste backfill operation in Namibia and reduces mining dilution, decreases surface tailings, and improves ore recovery. RPZ operates an underground zinc-lead mine in southwestern Namibia. The mine, which has been in continuous operation since 1969, producing zinc, lead, and silver concentrates, was acquired by Appian in June 2023. 

Alex Mayrick, general manager, Rosh Pinah Zinc, commented that, “Commissioning the paste fill plant represents another major step forward for RP2.0. These facilities enhance the efficiency and sustainability of our operations. With construction now more than 85% complete, we are firmly on track, on schedule, and on budget to deliver the RP2.0 expansion safely and responsibly. In parallel, our exploration program is delivering encouraging results, reinforcing the strong growth potential of RPZ as we continue to build a larger, longer-life operation.” 

RP2.0, which is intended to nearly double RPZ’s mine’s processing throughput to 1.3 million tonnes per year, continues to advance on schedule and on budget, with overall construction progress reported to now surpass 85%. Completion is expected in Q3 2026, with ramp-up commencing shortly thereafter. 

Ignacio Bustamante, head of Base Metals at Appian, added that, “The commissioning of the paste fill plant demonstrates RPZ’s ability to execute on key milestones and deliver modern, sustainable infrastructure. This achievement further strengthens RPZ’s operational foundation as we approach the final phases of construction. 

The ongoing exploration success highlights the upside potential beyond RP2.0, supporting long-term value creation for all stakeholders.”
