Deposit name(s): Mary River - No. 2 (occurrence)
Political location(s): Canada; Province or state: Nunavut; Subprovince or locality: North Baffin Island
NTS map data: 037G05
Deposit clan (type): iron formation
Deposit (sub) types: Algoma type; Reference: Watts Griffis and McOuat Ltd., 1983: A Summary Report on the Mary River Deposit of Baffinland Iron Mines Ltd. (062161); Mineral Assessment Report, Baffinland Iron Mines Ltd., Indian and Northern Affairs Canada, Publication code 062161
Deposit status: advanced project; Size category: significant; Status comments: Estimated 7 million tons to a depth of 350 ft based on geological data and 22 trench samples with 68.03 % total Fe.
Geologic province: Canadian Shield
Geologic subprovince: Rae craton
Geologic district: Committee belt
Deposit object located: centre of mineralized zone
Commodities: Fe
Geological ages: Archean (mineralization)
Archean (host rocks)
Host rocks: (1) sedimentary; iron formation; Metamorphic grade: amphibolite - lower; Component: mineralization zone
External host rock forms:tabular sedimentary body
Internal host rock structures:massive
fine grained
Individual lithologies:iron formation - oxide
Host rock stratigraphy:Mary River group
Metallogenic signatures: Fe
Mineralogy: (mineralization - massive / mineralization zone): hematite, specularite
Deposit shape: tabular; Component: mineralization zone
Deposit dimensions:length: 2,000 ft
width: 130 ft
Qualified comments: (Applies to: location and access) Located 1.5 miles east of the No. 1 deposit at an elevation of 2,150 feet above sea level, Deposit 2 forms a 2,000 foot long ridge surrounded by glacial drift.

(Applies to: mineralization) The ore body forms a 2000 foot long ridge and the inferred width varies 20 to 230 feet, though the maximum continuous width is 130 feet. The orebody strikes E-W and dips steeply to the south. It consists exclusively of dense, fine granular to platy specular hematite.

(Applies to: reserve/resource descriptions) Estimated 7 million tons to a depth of 350 feet based on geological data and 22 trench samples with 68.03 % total Fe (1966). Both the outcrop and the magnetic anomaly data suggest a possible strike extension beyond the present high grade ore dimensions.
