Dear Dr. Beaton!
Submitted herewith is a supplementary report ont
UCAD ZDC GROUP
Sarant Township Ontario
Tuo diamond drill holes show that the causes of the eleotromagnetlo
and magnetic anomalies are magnetite*pyrrhotite replacement deposits in a
Toloanio series* The source of the float ore was not found. Assay result*
on split diamond drill core from the replacement son*s returned negative or
trace amount* of copper and gold. Additional detailed magnetometer data
show the extent and structural complexities of the magnetite replacement
deposit*.
The drilling and geophysical survey should be filed a* assessment
work. Additional exploration should be carried out to locate the source of
the float ore*
GENERAL
This report is supplementary to the report dated April 19, I960
and covers the results of diamond drilling and a magnetometer survey carried
geo'r'hvaiofal survey*. WH.E r e- e s tab 1 1 B bed 6nd served u t* control for bot:; the
diamond drilling and geophysical surveys. All drill hoi* locations are
referred to the cocanon corner of claims 22362, 22363, 26151, and 26153.
DIAMOND
Two holes were drilled to intersect the causes of the electromag
netic and magnetic anomalies at depth. The drill logs and assay results are
appended to this report. Drill bole 1-61 was a vertical hole drilled on the
ioe at coordinates 330 north and 200 east (90 feet north and 410 feet east of
post #3 of claim 22362). This hole was stopped on February 1st at a depth of
239 feet in granite. Sixteen feet of water and twenty six feet of silt and
glacial debris was found corer ing a volcanic tuff. A twenty foot magnetite-
pyrrbotite replacement sone was found at a depth of 194 to 3H feet. A
granite, believed to be intrusive in the tuff, was intersected at 229.5 feet.
The core froa the replacenent sone was split and saaqpled in five foot
sections. Assay results on four samples returned up to ,01 gold and .11
copper.
In order to re-establish the location of this hole at a future date,
sighting boards were established on the shore at 420 feet north - 170 feet
east, 210 feet north - 560 feet east, and 300 feet south - 210 feet east of
post 13 of olaia 22362.
Diamond drill hole 2-61 was an inclined hole started on the ioe at
HOO N end 400 W (1115 feet north and 185 feet west of post #2 of claim
22363} with a dip of 50 degrees and on an asiauth of 90 degrees. This hole
was started on February 4th and was stopped on February 12th at a depth of

39 feet of silt and gl&ci&I debris were found overlying an andeaitic Toloanic
flow. The drill hole intersected the f Iowa at an angle which was approxi
mately normal to the dip. magnetite-pyrrhotite replacement sones were
intersected at a depth of H? to 166 feet and 179 to 189 feet. Samples of
the core from the replacement sonea were assayed and returned negative
results in copper, gold, and silver.
Sighting boards were established on the shore at 1130 feet north -
270 feet west and 580 feet north - 150 feet east of post 42 of olaia 22363
in order to facilitate the relocation of this hole.
IttQKETOMETER SDRVEI
Coincident with the drilling program a detailed magnetometer sur
vey was carried out on the ice on claims 22361, 22362, 22363, 22364, 26151,
and 26153* Traverse lines were 100 feet apart and the stations were at 50
foot intervals. The magnetometer data nore clearly define the zones of
magnetite-pyrrhotlte enrichment and show the varied and complex configuration
of the deposition. The drilling tested two of many favourable areas mapped
by the geophysical surveys. The results show a magnetic and conductive
one with a very low tenor of value lying on or near the granite contact.
An anomalous sone 600 feet away from the granite contact also returned
negative results. Other conductive tones with or without magnetic correla
tion are still to be tested. Several possible shear cones normal to the
strike of the volcanic series are worthy of further consideration.
It ts puggested that the drilling *nd possibly the jnagnetowetar
surrey be submitted aa assessment on the claim group and especially on
clalM 22362, 22363, 22364, 26151, and 26153. A more detailed investigation
of the float occurrences should be nad* with an attempt being nad* to corre
late tha float with the drill hole data.
All of which is respectfully submitted.

Purpose for Survey JLDescription of Instrument
The purpose of the survey was to determine if electromagnetic conductora might be found on the group of claims in question*
The electromagnetic survey was performed with the Squires type vertical loop gear. It consists essentially of a motor generator, which energizes n vertical transmitter coil, which in turn sets up a primary electromagnetic field. The signal from the primary coil is received by a horizontal receiving coil. Any conductor in the vicinity produces a secondary electromagnetic field, which distort? the primary field. This distortion is measured by the receiving coil in degrees *ji terms ef dip angles to the north or south.
When traversing from north to south a change in dip angle from north to south means that a true cross-over indicating an electromagnetic conductor has been established, whereas i change in dip angle from south to north means that a false cross-over has been established. This type of cross-over does not indicate a conductor.
Method of Survey A Presentation of Results
A picket line grid system on the claim group was completed by Central Geophysics Limited. A base line was installed running at H 50 B. Picket lines at right angles to the base line were spaced at 400 foot intervals. Electro-magnetic readings were taken at 100 foot intervals along the picket lines, In some cases E.M. readings were overlapped for traverses over the same line from different transmitter stations. Transmitter stations are marked on the map by a triangle and a letter of the alphabet. A line of readings from a particular transmitter station is marked on the map by the same letter as used to designate the transmitter location.
Cross-over locations are indicated by a solid circle for a well defined cross-over and by a solid semi-circle for a weak or poorly defined cross-over.

Dear Dr. Beaton:
Submitted herewith is a recent report on:
Magnetometer surveys Float Bay - Savant Lake Ontario.
A magnetometer survey has been completed over the anoraolous zones (electro-magnetic) on clainis- .26151, 26153. 22361. 22362, 22363 and 2236^, in Savant Township" ' - "
The survey mapped in grea*- detail the mineralized zones as well as the structure of the host rocks. The magnetic data controlled the diamond drilling. The survey was completed during the winter on the ice and no surface geology was exposed. -
The survey was completed in January 1961. A Sharpe A-2 magnetometer with a sensitivity of 18.1 gammas per scale division was employed. Four hundred and ninety one (491) stations were established on 3,500 feet of base line and 28,200 feet of traverse lines. The following is a break down on raan-days spent on this project:
