Rosh Pinah Zinc commissions water treatment plant, reinforcing ESG commitment

Rosh Pinah Zinc (RPZ) and Appian Capital Advisory Limited (the investment adviser to long-term value-focused private capital funds) have announced the successful commissioning of a new water treatment plant – a key component of RPZ’s sustainability strategy as part of its RP2.0 expansion project.

The new water treatment plant is designed to retreat and recycle process water generated across RPZ’s operations, significantly lowering the mine’s dependency on raw water addition from Namibia’s Orange River.

The investment reflects RPZ’s commitment to responsible resource stewardship and forms an important component of its environmental strategy as the operation scales to higher production levels under the RP2.0 expansion.

Water management is a critical consideration for mining operations in the region, where the Orange River is the principal source of fresh water. By recycling process water at scale, the water treatment plant reduces RPZ’s environmental footprint and supports the long-term sustainability of the operation and the surrounding communities that depend on shared water resources.

The commissioning of the water treatment plant follows the recent commissioning of Namibia’s first paste backfill plant at RPZ, and represents another operational advancement as part of the RP2.0 expansion project.

Overall construction progress on RP2.0, which will double RPZ’s production output, has now surpassed 90%. Completion is expected by the end of 2026, with ramp-up commencing shortly thereafter.

Ignacio Bustamante, head of Base Metals at Appian, comments: “Commissioning the water treatment plant is an important step in delivering on our environmental commitments as we scale the operation under RP2.0. Responsible water management is critical to both our operations and ESG standards. This milestone demonstrates our commitment to building a sustainable, long-term operation with a high standard of environmental stewardship.”
