Lithology Comments

Jan 31, 2017 (A Wilson) - The mining claim area is situated in the southeast border zone of the Glamorgan Gneiss Complex,and is underlain by amphibolite, granite, gneiss, and minor amounts of marble. The property is predominantly underlain by quartzitic and quartzo-feldspathic paragneiss and amphibolite, with lenses of granitic and syenitic pegmatite, and isolated lenses and two relatively continuous bands of marble and lime silicate rocks. Marble can contain tremolite-actinolite, phlogopite, and apatite. Calcite-filled veins cutting granite in places carry various amounts of biotite, amphibolite, apatite, titanite, feldspar, and rarely small grains of uranothorite.




Mineralization Comments

Jan 31, 2017 (A Wilson) - Chemical assays ranged from 0.11 U3O8 to 0.23 U3O8.
