Recent drilling efforts are increasingly focused on infill and expansion programs to de-risk the mine plan and test deep extensions of the high-grade zones.

Full-scale construction of the processing plant is slated to take 18–24 months.

The feasibility study projected an All-In Sustaining Cost ( AISC ) of approximately US$758–$760 per ounce , positioning it as one of the lowest-cost mines in Canada.

Final environmental approvals and a formal Board Investment Decision (FID) are expected in the second half of 2025 or early 2026.

Continued expansion drilling outside of the existing Mineral Resource Estimate (MRE) blocks has confirmed the presence of new high-grade mineralization that remains open for further growth.

The project is currently in the , with Gold Fields aiming for aggressive development timelines:

Windfall is ranked as a top 10 gold deposit globally by head grade, with reserves averaging 8.1 g/t gold .
