In only one ease did the vertical loop survey

this one ca&e, a very good check was obtained and it IB
located in claim P-67&BB and is marked "A" on the map.
The cross-overs marked X check quite well with axis of
the previously indicated conductor and the sone tee a

The magnetic survey was confined to the area of
this conductor and there is what appear B to be a north

INTRODUCTION
Nisto Mines Ltd* and Jelex Mines Ltd* hold a
group of claims jointly in Reid township* The following
report and accompanying map describes the results of
the survey.
PROPERTY AND
The property consists of 51 claims situated in
the southwest corner of Reid township. Porcupine Mining
Division, Ontario, as shown on the accompanying map.
The claims have been registered with the Ontario Department
of Mines as follows:
P-67749 to P 6?75S inoluslv*
P-67762 and P 67763
P-67767 and P 6?76d
t- 2 - PROSPECTING GEOPHYSICS LTD.
P 67773 and P 67774
P 67773 to P 67730 inclusive
P 677#3 and P 677S4
P 67799 to P 67812, inclusive
P 67336 to P 67393 w
P 6S63S to P 63686 w
GEOLQQf
As all the area covered by the c laims ie overlain
by a fairly thick layer of glacial drift, geological
information is virtually non-existent, The geology of
the area is covered in the Annual Report of the Depart
ment of Mines, Vol. UH|* Part J2* 1944, and by Map
No. 2046, published by the Ontario Department of Mines.
EIIJCTROMAGNETIC SURVY AM
The electromagnetic survey was carried out over
the entire property along north-south lines cut at 400
foot intervals, as shown on the accompanying map* The
equipment used consisted of a Ronka Mark ffi electro*
magnetic unit with a 300 foot coil interval.
An examination of the map shows throe possible

weak conductive zones which appear to be more or less
parallel. All the responses are quite weak and may be
due to conductive overburden rather than a conductor in
the underlying rooks* However , as the condic tors ali
have a similar trend, they may be deep-Seated conductors
in the underlying rooks*
SURVEY METHODS AND
The electromagnetic survey was carried out using
the Ronka Mark IV horizontal loop equipment with a 300
foot coil interval, in the horizontal loop l*ype of survey
both the in-phase and out-offi&ase components of the1 ' ) ' ; ' .' v ' -
secondary field are measured, whose special characteristics
make possible a fairly accurate evaluation of the conduc
tivity. A conductor caused by sulphide mineralisation
will produce a curve going from positive reading s through
eero to negative and back again to positive, Both the
in-phase and out-of -phase readings show the same general
curve, The ratio between the in-phaee and out-of -phase
readings over a conductor is an indication of the con-' ~ r ! i * ' .
ductivity of the body. A good conductor would cause a
greater deviation of the in-phase component than the
4 - PROSPECTING GEOPHYSICS LTD.
out-of-phase component, the opposite le tcttft of a poor
conductor. , V
In some areas secondary currents are Induced in
swamps and lakes. These anomalies can usually be dis
tinguished from a regular conductor as they cause a
response of the out-of-phase component with little or no
deviation of the in-phase oowponent*
CONCLUSIONS AND RECOMMENDATIONS
The electromagnetic survey indicated three weak
conductive zones all having an east-west strike, fhey
could be due to overburden but the parallel trend of the
zones suggests that they may represent conductors in the '. ' . ' ' '; \ '" -
underlying rooks* As a result, they warrant further
exploration that would yield a deeper penetration, A
vertical loop electromagnetic survey with a large coil
interval is suggested as this should determine whether
they are due to conductive overburden or a conductor in
the underlying rocks*
