Regional and Local Geology | | | Regionally, the Pickle Crow Property lies within the Uchi subprovince of the Canadian Shield, the same belt of 2.7-3.0 billion year old metavolcanic and metasedimentary rocks that host the deep, rich mines of the Red Lake area, including Goldcorp’s high grade Red Lake Mine. Gold deposits in the Uchi subprovince are known for their excellent continuity in the depth dimension.
The Property area is located within the Pickle Lake greenstone belt of the Uchi subprovince, the term “greenstone” referring to the greenish hue of one of the principal rock types, chiefly metabasalts (metamorphosed mafic lavas), that comprise the belt. The Pickle Lake greenstone belt is an approximately 70 kilometre long by 25 kilometre wide area of supracrustal rocks and internal granitoid plutons surrounded by large granitoid batholiths. The supracrustal rocks have seen polyphase deformation and been metamorphosed to greenschist facies with amphibolite facies occurring in the thermal aureoles of younger plutonic bodies.
Locally, on the Property itself, the principal rock types are metabasalts (greenstone) with intercalated metasediments, principally carbonate-magnetite banded iron formation, as well as quartz-feldspar porphyry and felsic to intermediate volcanic and volcaniclastic units. | | |
