    Claim L578379 Garrison Twp,


    The property consists of one claim L578379, a restaking of claim 26388.

    Location and Access

    The claim is located l*j miles west along Hwy 101 from the Garrison/Harker twp line. The highway crosses the claim.


    No outcrop is believed to occur on claim L578379. On the claim adjoining west an outcrop of carbonatized greywacke occurs as part of a larger sedimentary zone which strikes across almost the whole width of Garrison twp and appears to be bounded on the south by the Destor-Porcupine fault and on the north by what may be the Munro fault. Immediately north and south of this structure lie intermediate to basic volcanic flows. The large Garrison stock, which is mainly granitic, lies a short distance to the south and the east- westerly trending peridotites etc., of the Ghost range occur as a sill a few thousand feet to the north. Minor dikes and other intrusions of varying composition are super imposed on this pattern.

    The sedimentary band may have economic significance because of gold occurrences west of claim L578379 on the Brydges, Newfield, Garrcon, and Hastings properties. Newfield, in particular, is reported to have encountered commercial gold grades from drilling in a syenite or feld spar porphyry which lies within this zone of faulted sediments,

    Surveys 1981

    Personnel The lines were cut by A. Foster of Matheson, Ont.

    Survey readings were taken by L.G. Hobbs of Markham, Ont.

  • t Control Locating the base line along the north edge of Hwy 101,

    four lines were turned off at an angle of 760 to run true north. The baseline and cross lines* which are 400 feet apart total 1.48 miles in length. All the field work was done in August and September of 1981.

    Magnetometer Survey

    A GEM GSM 8 proton total field magnetometer was used

    with diurnal corrections by the time-linear method. A

    total of 62 stations were read on loops from a base station

    at L4W IN.

    Interpretation A general increase in magnetic strength from south

    to north with a wide "plateau" through the centre of the claim is observable. The magnetic peaks at 12W, 4N and 8W, IS may be evidence of a northwesterly trending olivine diabase dike which appears on Satterly*s map of the township on the claim immediately to the south. The wide east-west line spacing of this survey may be causing this feature to be obscured. There appears to be a magnetic zone trend ing slightly north of east across the top of the survey which would roughly correspond to the assumed location of the Munro fault.

    VLF Survey The instrument used was a Geonics EM16 and the

    transmitting station used was NLK (Seattle). A total of 60 stations were read. A Fraser reduction was applied to the In Phase readings and it is these values that are plotted on the VLF survey map. For this reason readings appear between picket stations on the plan although readings were of course obtained at the stations themselves.

    Interpretation A broad rather weak conductive zone occurs extend

    ing from the central part of the claim eastward and off it. Its termination to the west suggests either the presence of

  • the diabase dike referred to in the previous section or a northerly trending cross fault between lines 8W and 12W.

    Conclusions and Recommendations

    1. More detailed readings in the 6W to 12W area would probably help the interpretation of these surveys.

    2. A broad magnetically flat zone occurring on lines O and 4W in the area just north of the road corresponds to a broad moderate conductor. The interpretation of this is not clear but it may represent an Algoman intrusive plug within the sediments with a weak east-westerly trending unidentified conductor crossing it. In the case of renewed gold exploration of the sediments in this belt a test hole should be considered.
