Limits
- This is a dated synthesis of public government and issuer documents, not independent field reporting. Later decisions and design changes require a new source review.
- No current mineral resource, mineral reserve, mine economics or funding sufficiency is established by this dossier. Selected assay results do not establish those measures.
- The proposed Tamarack mine, the Vault exploration zone and the Beulah processing proposal are related subjects, not interchangeable project boundaries or operating assets.
