The twenty six claims covered by the survey are:

ACCESSIBILITY

Access to the property is most readily achieved by floi.t

or ski equipped aircraft. The closest commercial airbase is that

of Rusty Kyers^ situated at the north end of Sturgeon Lake, approip-.atel.

twenty miles north north west of the property.

GEOLOGY

Geology of the area is contained in the Ontario Department

of Kines Geological Report #24: "Ketionga Lake Area" by David P.

Rogers, 1964. A detailed geological map and report covering the

claim group has been previously submitted.

PREVIOUS WORK

Previous work consists of: line cutting, geological

mapping, E. M. survey (Crone J.E.K.) and a magnetometer survey.

THE SURVEY

A V.L.F. survey was carried out using the Geonlcs E.t-'. 16.

This instrument is a 'one man instrument utilizing low frequency

radio waves transmitted from military transmitters situated around

the globe. A station in t-he same direction as the geological strike

;{V i*'.

chosen in order to give a maximum coupling with the conductor.

The direction of thti magnetic component of the transmitted field

is horizontal and perpendicular to the geologic strike. The field

direction and thus the travers direction is perpendicular to the

transmitter location.

The E,K. 16 measures the secondary field generated by

conducting bodies when they are subjected to the transmitted primary

field. The receiver has two inputs, with two built in receiving

coils; one coll has normally vertical axis and the other is horizontal.

The signal from the vertical coil is minimized by tilting

the instrument. The tilt angle is measured in percentage. The

remaining signal in this coil is finally balanced out by a measured

percentage of a signal from the other coil after being shifted by

90 degrees. This coil is normally parallel to the primary field.

' The survey was carried out by W. H. Keakin betweens'

October 15 - 30 1973 under the supervision of Peter G. Cooper,

geophysicist.

Using the existing grid lines, readings were taken at

100 foot stations with additional readings at 50 foot intervals

across anomalous zones. Line spacing is 400 feet. In all, ^-1^7,

stations were occupied, 917 one hundred foot stations and 220

intermediate stations. All readings were taken with the operator

facing north. North dips are designated plus; south dips minus

From this data two maps have been compiled; a profile

map from values at 100 foot stations and a contoured map from

processed data at 50 foot intervals using the D. C. Frazer method.

PURPOSE OF THE SURVEY.

The previous E.M. survey indicated twelve seperate

conductors. The present survey has clearly connected nany of these

along, strike, defining six recognizable zones and pin pointing^^

..l, -'

;.f "- ' - - ' 3

drill targets within these zones.

RESULTS AMD DISCUSSION'S

The six principal anomalous zones have been designated

A, B, C, D, E, and F. All these anomalies occupy long structural

features and all have magnetic correlation with the exception of

anomaly E.

TONE A maintains a fairly uniform width of 200 feet and contains

a central core of several elongate lenses of high conductivity. On

line 28E at 500N rusty outcrop was observed and at 600N in the vicinity

of lines 40 and 44E, beneath the roots of blown down trees, the topsoil

is red with rusty oxide. This anomaly is undoubtably due to sulphides.

ZONE B This conductive zone varies in width from 200 to 450 feet.

Rusty outcrop was noted on the base line at 52E. On the base line

at 64E some shallow "pop-shots" reveal heavy pyrite-pyrrhotite

mineralization. Several lenses of high conductivity are contained

within this zone.

ZONE C This zone, more complex than A and 3 is about 400 feet wide

at the west end. The central part contains one or possibly two lenses j

of none conductive material wheras the eastern extension divides !

into two closely parallel zones. The magnetics exhibit greater

intensity over the south or footwall side of the occurrence, possibly \

indicating zoning of the sulphides. Rusty outcrop was observed at

1400N on line 44E. At 2000N on line 40E e email creek draining to

the north is depositing a rusty precipitate. On the south side of

the zone at 1300N on line 48E a stagnant swamp area contains rusty

precipitate.

70\TES D 6 F Both of these conductive zones have pronounced magnetic

correlation. Though no physical evidence as to their cause was

noted, sulphide mineralization is suspect. j

ano.aliec. In order to ^ evaiuate these occurrences however, a

prograde of diamond drilling would be necessary.
