Summary
White Gold Corp. announced a positive maiden Preliminary Economic Assessment (PEA) for its flagship White Gold Project in Yukon, Canada, outlining a 9.4-year open pit operation. The PEA projects an after-tax NPV(5%) of C$1.9 billion, an IRR of 38%, and a 1.7-year payback period at a US$3,600/oz gold price, with average annual gold production of 188,000 ounces. The study is based on an August 2025 resource estimate of 1.73 Moz Indicated and 1.27 Moz Inferred gold, and metallurgical testwork indicating 92% recovery for key deposits but 72% for others due to preg-robbing.
Reasoning: The maiden Preliminary Economic Assessment for the White Gold Project demonstrates robust economics and significant growth potential, establishing a strong development framework for the district, despite the preliminary nature of the study and some metallurgical challenges in specific zones.
Positive factors
- Maiden PEA outlines strong economics with a C$1.9 billion after-tax NPV and 38% IRR.
- Significant production scale of 188,000 oz/year over a 9.4-year mine life.
- Efficient cost structure with LOM AISC of US$1,480/oz.
- Project located in a favorable and stable mining jurisdiction (Yukon, Canada).
- Identified significant growth potential from resource expansion, underground mining, and exploration pipeline.
- High gold recoveries (92%) for Golden Saddle and VG deposits.
Negative factors
- PEA is preliminary in nature and includes Inferred Mineral Resources, which are considered speculative.
- Lower gold recoveries (72%) for ARC and Ryan's Surprise deposits, with preg-robbing identified.
- Drill results from 2025 and current 2026 drilling are not included in the current resource estimate.
Low confidence — this extraction should be reviewed alongside the original source.

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
