63ilm SOMMARY
During the period November 25 to December 2 of
8 1969 electromagnetic and magnetic surveys were conducted
m over the mining property of Lake Kozak Mines located in
the Bast half of lot 8, concession No. l of Morgan Township,
l Two anomalous rones are indicated by the electro-
B magnetic survey. One of these is a concident magnetic and
electromagnetic anomaly.
8 The property has merit and a program of geological
B mapping is recommended.
A diamond drilling program will then be considered
B on the basis of this program.

ll l PROPERTY
The property consists of 160 acres contained in
p the east half of lot 8, concession No. l, Morgan Township
in the District of Sudbury, Ontario.lLake Koeak Mines optioned the property and by
l agreement have completed a geophysical program over that
m ground. They have an 8096 interest and by payment of $20,000
over a five year period will retain this interest.
lB HISTORY
According to the private report of T. W. Kierans,
8 January 31, 1966, the first title to the property dates
l from April 6, 1911 when Hoe St. J*;an acquired the south-east
quarter with full mineral rights under Free Grants and
" Homesteads Act.
8 On March 21, 1912, he acquired the north-east
quarter under the same act.
Several transfers have been recorded since then,
8 the last in 1965 from Zaduk and Kovacs to Xovacs (vole).
Lake Kozak Mines optioned the property obtaining
an 6096 interest by completing a geophysical program before
8 May l, 1970 and retain, this..interest, by. payAog.-t^e amount

ll *l of $20,000 over a five year period.
" GENERAL GEOLOGY OF THE SUDBURY BASIN
l The geology of the basin can perhaps best be
^ understood from a chronological description of the events
during this span of nore than a billion years. The earliest
l known footwall rocks resulted from the outpouring of lava
g flows known as the Elsie Mountain Greenstones and the
accumulation of sand.
l On top of these sediments) mainly sands, clays,
^ gravels-were deposited from marine waters and, at some
stages, fresh waters. Interlayered with these sediments are
I lava flows and ash beds from renewed outbursts of volcanic
f activity. After deposition, the layered rocks were folded,
faulted, metamorphosed, and intruded by granite. Uplift
l followed by erosion removed many thousands of feet of these
m rocks and left a surface of low relief.
On this surface, material of the Whitewater
8 series accumulated. The complex remnants of the basal member
B indicate an initial deposition of sand. The sand was buried
in time by the Onaping tuff, a mass of ash and pumice, like
l material four thousand or more feet in thickness which
B accumulated rapidly during a severe crustal disturbance.
" A. C. A. HOWE INTERNATIONAL LIMITED
im Related fracture patterns and dikes of breccia, commonly
known as Sudbury breccia developed at the same tine in ali
l the pre-existing footwall formations. The Onaping tuff
l in turn was covered by a thin zone of carbonate rich-sediment,
then by several thousand feet of clay - Onwatin formation -
and finally by an unknown thickness of impure sand called
l the Chelmsford sandstone.
GEOLOGY OF PROPERTY
l The northern two-thirds of the property is under-
lain by partly exposed (4096) Precambrian Volcanic rocks
* consisting of southward dipping and east-west striking
8 bedded tuffaceous sediments, described by W. H. Collins as
the Onaping formation. The southern third is farmland
(fields composing 1/5 of entire property) and swamp land
l consisting of an unknown depth of overburden covering the
g strike of the Cameron Creek fault zone.
l SURVEYS COMPLETED
m Magnetic and electromagnetic surveys were done
on profile lines spaced at 400' intervals north of and 200'
l intervals south of an east-west base line.
li A. C. A. HOWE INTERNATIONAL LIMITED
fl *l Regular stations were established at 100*
. intervals along the flagged lines.
The Magnetic Survey
f The magnetic survey was done using a Sharpe MF-1
m Fluxgate Magnetometer Serial No. 702258. Regular readings
were taken at 100* stations along the picket lines. Fifty-
l four (54) intermediate stations were established.
m ( Instrument Details, Appendix 1). 4.3 miles of survey were
completed.
8 The Electromagnetic Survey
: The electromagnetic survey was done using a
Geonics Model EM-16 VLF electromagnetic unit. (See Details,
lm Appendix 11). Determinations of the resultant EM field
fl were made at regular 100' station intervals on the established
grid. 4.3 line miles of survey were completed. Sixty-
l three (63) intermediate determinations were required.
lCONCLUSIONS AND RECOMMENDATIONS
" There are two definable electromagnetic anomalies
l within the survey area. These anomalies have been numbered
l and 2 for reference.
Anomaly No. l is a two line anomaly located on
l
l A. C. A. HOWE INTERNATIONAL LIMITED
j
l
line 0-K)0 and 400 'E and approximately 700 feet north of the
east-west base line. A magnetic anomaly is concident withmm
this anomaly. Outcrop is exposed in the vicinity of this
J anomaly but could not be mapped because of snow conditions
m at the time the geophysical surveys were completed.
Anomaly No. 2 is an electromagnetic anomaly which
g has no magnetic correlation. It is located north of the
m east-west baseline on lines BOOR and 1200E but is strong
only on line 1200E. The anomaly occurs along the edge of
l a swamp area adjacent to a steeply rising outcrop which
m indicates that the cause is a clay edge effect.^* '
Anomaly No. l does merit further work and a
8 program of geological mapping is warranted.
B A program of diamond drilling will then be considered
on the basis of previous geophysics and the geological mapping
program.

TECHNICAL DETAILS
GEONICS LIMITED E.M. 16
The E. M. 16 Unit acts as a receiver measuring the vertical components ol the secondary magnetic fields induced in conductive bodies by an alternating horizontal magnetic field originating from VLF-transmitting stations. The instrument utilizes vertical and horizontal coils to measure the in-phase and quadrature components of the secondary field. Dials on the inclinometer permit the in-phasc component to be read in positive or nega tive percentages and in degrees.

Frequency range: 15-25 kHz
Accuracy of readings: ^ I fv r esolution
Range of Measurements: In-phase j^ 1507o or J^ 90CQuadrature * 40"7o
DESCRIPTION OF METHOD
To use this instrument, survey lines arc selected approxi mately along the linos of the primary magnetic field, (i.e. right angles to the station providing the primary field). Readings of the in-phase and quadrature components arc- obtained by minimizing the sound intensity in the headphones through swinging the instrument back and forth and by adjustment of the quadrature component dial on the instrument. Readings were taken with the operator facing in the same direction in order not to reverse the polarity of the readings.
Plotting the survey results, conductors are indicated by the amplitude and position of high and low readings.
