Qualified comments: |
(Applies to: location ) The location of Area E iron formation was taken from AR 080645, Figure 7.
(Applies to: location and access) Normin showing Ayergotadlik River (047ASW0003) may be same as this? However Normin shows no commodities.
(Applies to: rock analysis and sample assays) Potential tonnage from planimetry and surface studies was estimated to be 86 million long tons (Ref ID - 2688).
(Applies to: mineralization) (see "Deposit A" for general comments)
Deposit E is 823m in length and averages 125m in width.
