i want you to remember this part of the government page
sounds like some that is on company web page.. make notes of what is there.

Deformation that affected the Paleoproterozoic lithologies of the Moran Lake, Post Hill and Aillik groups was accompanied by widespread and well developed metasomatic assemblages such as those at the Post Hill, Michelin North, Michelin South, Emben and Burnt Lake properties (Geological Survey of Newfoundland and Labrador, 2003; Marshall et al., 2003). "Alteration is hosted within sedimentary/volcanic sequences, as well as syn-Makkovikian plutonic bodies such as the Melody Hill granite. Most widespread are broad zones of Na-(Ca) alteration, characterized by albite-(actinolite-epidote-clinopyroxene-garnet-calcite-quartz)-rich assemblages. In places, as at the Michelin deposit, uranium enrichment occurs with Na-(Ca)-rich metasomatic assemblages. Narrower zones of Fe-(K-Cu-Mo-U)-enrichment are also common and are characterized by concentrations of one or more of magnetite, hematite, mafic silicates (amphiboles, pyroxenes), pyrite, chalcopyrite and molybdenite. These zones are typically associated with uranium enrichment." (excerpts from Marshall et al., 2003). Sericite-hematite alteration zone with disseminated sulphides and abundant REE mineralization and hematite and carbonate-rich breccias also occur locally. Alteration, including magnetite alteration and mineralization at the Post Hill property are associated with the Kaipokok Bay shear zone.
