Access Description: The Bending Lake Iron Deposit is located 280 km northwest of Thunder Bay along Highway 17 and 25km south along Highway 622. The deposit is accessible by a well-maintained logging road and crosses Highway 622. Bending Lake Iron Group has acquired 49 mining patents, 10 patents with the associated 1584859 Ontario Inc and 32 mining claims (Jan 12/08) with associated Windigo Ridge Resources Inc covering a 50km2 area. (Bending Lake Iron Group, PDAC Handout, 2009)



Exploration History

Iron exploration began in the Bending Lake area in 1933 with mapping by Thompson, Ontario Department of Mines. In 1953-55 and 1963-65, Jalore Mining Company Ltd completed mapping, ground magnetic surveys, drilling and mineralogical testing. In 1967, Algoma Steel Ltd did further mapping, drilling, mineralogical testing and completed a preliminary feasibility study. In 1975-77, Steep Rock Iron Ore Mines Ltd completed more drilling, environmental surveys, a bulk sample (354 tons) and a second preliminary feasibility study was completed. They released a historical resource of 249 Mt of 28.19% Fe.

Geology

Province: Superior

Subprovince: Wabigoon

Belt: Eagle-Wabigoon-Manitou

Geological Age: Archean  



Geology Comments

Jul 06, 2022 (Q Unknown) - The Bending Lake Iron Deposit is located within the western region of the Wabigoon Subprovince of the Archean Superior Province. The Bending Lake property is located within the 70km long by 30km wide area known as the Stormy - Bending Lake Greenstone Belt. It consists of differentiated mafic to felsic volcanic rocks, that are overlain and interbedded with clastic and chemical metasedimentary rocks with a broad, southwest dipping synform. This package is bounded to the north by the Revell Batholith and to the south by the Irene-Eltrut Batholitic Complex. The folding and thickening event as produced large volumes of economic iron ore.




Mineralization Comments

Jul 06, 2022 (Q Unknown) - The Bending Lake Iron Deposit is a classical Algoma type iron ore deposit. The banded iron formation is blue-grey to black, fine-grained, well-bedded unit of magnetite with minor hematite, specularite, biotite, amphibole, chlorite, garnet, pyrite or pyrrhotite. It is interbedded with quartz-biotite garnet schist. The iron formation average thickness is 90m and has been traced over 9km in outcrop but aerial magnetic surveys show it extents up to 14km. A historical average grade of 28.19% Fe has been located along a 1150m long by 330m wide, thickened zone containing 249 million tons of iron ore. There are five mineral showings (Cu, Zn or Au) related to Volcanogenic Massive Sulphides on the Bending Lake property but further work is needed to better define these other showings. There are two other iron showings (Stormy Lake Fe and North Fe) on the Bending Lake property. The Stormy Fe showing is related to the regional folding event (synform) but no detailed work has been completed to date. The North Fe is a >2km northwest extension of the magnetite-bearing iron formation with 92m true width. Further work is needed to better define these other Fe showings.
