    Dear Mr Mosher:

    Submitted herewith is a report on;

    MOUNTAIN ISLAND BAY CLAIMS PATRICIA MINING DIVISION

    ONTARIO

    Ground geophysical surveys mapped two anomalous zones which are thought to be caused by infolded bands of conductive sediments. It is recom mended that the geophysical reports be filed for assessment credit.

  • 2.

    GENERAL

    The Mountain Island Bay area of Sturgeon Lake is

    located approximately 45 miles north of Ignace on Highway 599.

    The survey was run over the following mineral claims:

    218537^21854^ 218551- 218554'^ ^ ^

    218541^ 2185.49' 218552 218555'

    218545^ 218550 , 218553

    which are held under option by Chimo Gold Mines Limited with

    Mr. J. McNeil.

    The geology of this area is shown as Geological Map

    No. 2169 "Sioux-Lookout - Armstrong Sheet" by the Ontario

    Department of Mines. Airborne magnetometer data covering this

    'area is published in Geophysical Paper 1127-G "Witcomb" by the

    Geological Survey of Canada. This area is coded under the

    National Topograph Series 52-G-14.

    A grid system comprising of 54,000 feet including tie

    lines was carried out under the supervision of Mr. K. Kuhner

    of Thunder Bay, Ontario, during the first week of May, 1970.

    The baseline trends east-west with picket lines trending

    north-south at 400 foot intervals. One hundred foot stations

    were established on all lines.

  • 3.

    MAGNETOMETER SURVEY

    The ground magnetometer survey was completed under

    the direct supervision of D. G. Wahl, P.Eng., during the period

    of May 18 to May 20, 1970. A Barringer GM 102 Magnetometer with

    a sensitivity of 10 gammas recorded the total field magnetic

    intensities at fifty foot intervals on all lines, in excess

    of 900 stations were occupied.

    The magnetic data was reduced to a local datum and

    adjusted for magnetic diurnal. The data is presented on the

    enclosed maps as corrected station values and as a contoured

    interpretation of thece data.

    The andesite flows have a low magnetic susceptibility

    but are characterized by linear, trending anomalies marking

    individual flows.

    The pyroclastic rocks have a moderate magnetic

    susceptibility in the range from 400 gammas to 800 gammas.

    Associated with the pyroclastic rocks are strong

    elongate units having a magnetic susceptibility range from 1000

    to 1500 gammas. These elongate units are thought to be tuffs.

    The syenite intrusive is characterized by very low

    uniform magnetic susceptibility.

    '"I

  • EM SURVEY

    The electromagnetic survey was conducted by D. G. Wahl,

    P.Eng., during the period from May 18 to May 20, 1970, employing

    a Crone Radam VLF EM Survey Unit. This unit measured the

    inclination or dip and the total field intensity with a sen

    sitivity of l 0 of dip and 196 field intensity. The VLF station

    used is located at Seattle, Washington, having a frequency of

    18.6 KHz- All observations were taken facing w^st. Stations

    were occupied at 50 foot intervals on the established grid.

    Two conductive zoner. were mapped lying within the

    andesitic flows. These anomalous areas will be discussed in

    detail in a following section of this report.

    GEOLOGY

    The geology as published by the Ontario Department

    of Mines was extended and defined by the geophysical surveys

    and a compilation of the data is appended.

    The property occupies a portion of the north limb

    of an easterly plunging syncline of intercalated flows and

    pyroclastic rocks. The rocks dip gently into the syncline but

    the symmetry of the syncline is interrupted by an anticlinal

    roll trending approximately east-west. This anticlinal roll

  • * l

    e

    it is felt might be the surface expression of the syenite

    intrusive in the Mountain Island Bay area. 7* portion of

    syenite intrusive outcrops on the shore of Mountain Island

    Bay. This intrusive is also defined by the magnetometer survey.

    The attached map shows the rocks and rock structures

    as inferred from the field surveys.

    ANOMALY l

    This anomaly is located approximately 1000 feet

    south of the baseline roughly paralleling the contact between

    the andesite flow and pyroclastic rocks. It is characterized

    by an increasing field strength accompanied with a strong dip

    reversal. Anomaly l exhibits a very low magnetic susceptibility.

    Attached is a section showing the inferred geology. This

    anomalous zone is thought to be caused by an in-fold of con

    ductive sediments.

    ANOMALY 2

    In general an increase in field strength is directly

    related to an increase in the conductivity of the underlying

    surficial debris and bedrock and is inversely related to the

    resistivity of the causative body. It is felt that the clay

    filled valley of Ethlouise Lake causes the increasing field

    strength in the area of Anomaly 2. The possibility also exists

  • fi

    i l

    6.

    ~

    that this anomalous zone could be similar in structure to that

    of Anomaly l, representing the southern infold of the conductive

    sedimentp flanking the anticline.

    All of which is respectfully submitted.

    Sincerely yours,

    W. G. WAHL L
