Point Location Description: Outcrop of iron formation at roadside

Location Method: Field Visit

Access Description: Drive north from the junction of highway 101 and highway 17 towards Dubreuilville. Approximately 300 m south of the junction between highway 519 and highway 17 there is an outcrop of iron formation on the east side of the highway. Iron formation can also be found on the west side of the highway.

Geology Comments

Dec 07, 2005 (A Wilson) - The iron range is composed of 5 distinct southeast striking bands of iron formation. East of the highway, the stratigraphic equivalent package consists only of 2 major iron formations suggesting that there has been stratigraphic repetition of the units. The Brant Lake Iron Range is the western extension of the Dreany Iron Range and is stratigraphically younger than other ranges in the Kabenung Lake area.

Lithology

Lithology Comments

Dec 07, 2005 (A Wilson) - The iron formation consists of laminated to bedded chert and magnetite. Reports vary, but up to six parallel, south facing, steeply dipping bands of iron formation have been found. It commonly outcrops along low iron-stained ridges. The iron formation lies within metasedimentary rocks, just above the contact with intermediate to mafic metavolcanic rocks.

Mineralization

Mineralization Comments

Dec 07, 2005 (A Wilson) - Analysis of samples collected in 1902 returned 42%-49% Fe and 25-39% Si. Assays from the iron formation collected in 1910 returned iron values ranging from 41.7% to 50.44%. Assays from the 1911 diamond drilling returned iron values ranging from 28.56% to 43.14%. In 1957 low-grade samples containing 20.7% Fe were beneficiated to a concentrate containing 51.77% Fe. In 1966 a 55 lb sample of ore assaying 43.5% Fe was concentrated to 63% Fe.
