Lithology

Lithology Comments

Jun 04, 2009 (A Wilson) - On Iron Island shattered and locally brecciated quartz fenite predominates along the northern and northeastern shores, but aegirene-potassic feldspar fenite is present locally and increases in abundance towards the central part of the complex and predominates elsewhere on the island. On the other islands, fenitic rocks are mainly shattered, slightly fenitized granitic rocks and minor quartz fenite. All the fenites contain numerous carbonate veins, hematite-rich stringers, and lamprophyre dikes.

Mineralization

Mineralization Comments

Jun 04, 2009 (A Wilson) - A 5 ft section of Nipiron Mines Ltd. diamond drill hole 13 returned 0.30% Nb2O5 and 0.10% U3O8. A 9 ft section of the same drill role returned 0.30% Nb2O5 and 0.07% U3O8; and a 10 foot section of the same drill hole returned 0.30% Nb2O5 and 0.13% U3O8. Drill hole 17 intersected 0.366% Nb2O5 over 60 feet and 0.17% Nb2O5 over 72 feet. Two, 5 foot sections of drill hole 13 returned 0.08 and 0.05% Ni. Apatite locally forms as much as 20% of the silicocarbonatite exposed on Iron Island and is locally abundant in association with iron-titanium oxide mineral concentrations in the pyroxenitic rock. An assay of 0.15% tin over 9.4 feet is reported in the log for drill hole No. 1-S. Fluorite and barite are mainly confined to late veins that cut across the major phases of the complex; a 3-foot wide vein of fluorite-barite-carbonate is present in drill hole No. 13.
