Horizon Minerals Ltd Provides Pre-Feasibility Study Update
- Progressing Black Swan Pre-Feasibility Study to refurbish and repurpose plant to gold processing
- Comminution circuit design options evaluated, with preferred single stage crush plus SAG and ball mill configuration
- New gold recovery circuit including gravity and CIL plant being developed
Horizon Minerals Ltd is pleased to provide an update on the progress of the Pre-Feasibility Study (PFS) work currently underway at its 100% owned Black Swan Project. The PFS is focused on the refurbishment and repurposing of the existing Black Swan processing plant to a gold processing facility. GRES is in the final stages of completing the Black Swan PFS that incorporates refurbishment of the existing comminution circuit and the introduction of a new gold Carbon in Leach (CIL) processing facility. The plant has been designed for 1.5Mtpa throughput with equipment sized to achieve a product size of P80 106μm. GRES has completed a trade-off study and identified a preferred comminution circuit involving single stage crushing plus SAG and ball mill, which utilises the existing Black Swan comminution circuit and provides flexibility and robustness for managing future ore types and throughput rate increases. The new CIL beneficiation component of the study is also well advanced. High level scoping studies have been finalised by Mining Plus on 24 open pit and underground mineral deposits to provide potential ore feed for the Black Swan processing facility. Infrastructure and utilities components of the PFS are also ongoing. The PFS is on track for completion in the December 2025 quarter, after which Horizon plans to make a Financial Investment Decision and move to the next steps of refurbishment and commissioning.
The PFS is being completed on the plant refurbishment, infrastructure and mine feed sources, with the aim of providing a minimum life of mine plan of five years.
Subject to a positive Financial Investment Decision, construction could commence during 2026 to refurbish and convert the Black Swan processing plant to gold processing.
