Point Location Description: Occurrence
Location Method: Conversion from MDI
Access Description: The occurrence is located on the east shore of Black Bay approximately 14 miles south-southwest of the hamlet of Hurkett The occurrence is accessed by boat from landings at either Hurkett or Squaw Bay.
1896 Dr. A.P. Coleman of the Ontario Bureau of Mines reported an occurrence of magnetite iron sand on the east side of Black Bay 1932 J.S. Dobie shipped 200 pounds of black iron sand to the federal Department of Mines, Testing and Research Laboratory. The sample was tested, ' to determine the grade and character of the concentrate which could be produced by magnetic concentrate. 1936 W.B. Timm of the federal Department of Mines and Resources reported tests conducted on a 40 pound sample of titaniferous sand. The tests were to 'determine: (1) whether a clean magnetite iron concentrate could be produced; (2) whether a concentrate containing over 40% titanium oxide (TiO2) could be made.'. 1956 Steep Rock Iron Mines conducted tests on behalf of Alexander Phillips. The sample was assayed, screened, concentrated by both wet and dry magnetic methods and examined under binocular microscope. The sample was found to be uneconomic. 1993: The patented claims were listed in 1992 for sale as camp lots.
Province: Superior
Geological Age: Archean
Dec 07, 2005 (R Degagne) - The occurrence consists of a raised beach deposit of gravelly sand. The deposit is glaciolacustrine in nature and extends for approximately 4 km. The area is surrounded by glaciolacustrine deposits and hosts peat bogs and swamps. The underlying rocks are extrapolated as being Osler Group and Sibley Group sediments. The Olser Group overlies the Sibley Group rocks and are composed of massive and amygdaloidal basalts and sandstone. They unconformably overlie the Sibley Group sandstones.

Dec 07, 2005 (R Degagne) - Four samples were submitted for determination of their constituent minerals. BS1: the dark minerals included clinopyroxene, hornblende and minor titanite, magnetite (partly hematised), and biotite. Light minerals which are less abundant included pink garnet, orthoclase, plagioclase and quartz. Also present are assorted rock and wood fragments. BS2: the abundant dark minerals consists of clinopyroxene, hornblende, along with minor titanite, biotite and magnetite. Light minerals include plagioclase, orthoclase, quartz and pink almandine. Various rock fragments are also present. BS3: this sample contains magnetite (partly hematised), hornblende, clinopyroxene, and garnet. Large leucocratic grains consist of quartz, albite and orthoclase. BS4: this consists of magnetite, with minor pink almandine, clinopyroxene, ilmenite, amphibole, albite, and quartz. Occasional grains of yellow-green olivine are also seen. Analyses by Geoscience Laboratory, Ontario Geological Survey, Toronto CHEMICAL ANALYSIS: The six products obtained from the heavy mineral concentrate processing were sent for TiO2 analyses. The results were as follows: Sample Number: IM-93-001:1.25% TiO2, IM-93-002:1.18% TiO2, IM-93-003:4.11% TiO2, IM-93-004:3.16% TiO2, IM-93-005:3.52% TiO2, IM-93-006:3.36% TiO2.

Geologist: R Degagne
Notes: Visited in July, 1992 by P. Hinz | R. M. Landry, (OGS OFR 5889, 1994) . ECONOMIC FEATURES: Six samples were taken, combined and subjected to heavy mineral concentrate processing. The samples were sieved into two size fractions, passed through a Reading PR71 magnetic separator to obtain high magnetic, para-magnetic and non-magnetic fractions. Due to the high percentage of clinopyroxene and hornblende this process was not able to separate out the magnetite or ilmenite. COMMENTS/RECOMMENDATIONS: Although this occurrence is not of economic significance, it confirms the presence of titanium bearing black sands in the vicinity of the Black Bay Peninsula. In 1992 a contractor was drilling a water well and intersected 10 m of black sand at a depth of 9 m. A sample was taken and returned up to 7% TiO2. This, however, was not confirmed by the authors.
