REPORT ON VLF-ELECTROMAGNETIC
AND SELF-POTENTIAL SURVEYS

INTRODUCTION
During September 1983, VLF-EM and self-potential surveys were carried
out over the two-claim Ackerman gold property in Marmora Township.
Lines at 400 ft. spacing had previously been cut for magnetic and geolrr
ogical surveys, and the same lines were used for these surveys.
PROPERTY, LOCATION AND ACCESS
The property consists of two claims:
EO 538210 N/2 of E/2, Lot 6, Con VIII
EO 538211 S/2 of E/2, Lot 6, Con VIII
The claims are situated 4 miles east of the town of Marmora. Provincial
highway 7 runs a few hundred feet north of the north boundary of the
property.
GEOLOGY
The property has been mapped geologically by R. Ekstrom. The eastern
portion is underlain by granite or syenite of the Deloro pluton, while
the remainder is underlain mainly by clastic metasediments with a north-
south strike and a moderate westerly dip.
VLF-EM SURVEY
The survey was carried out using a Geonics EM-16 receiver tuned to
transmitter NSS at Annapolis, Maryland (21.4 KHz). Readings of in-phase
and quadrature were taken at 50 ft. intervals. They are plotted in
profile form on the map.
- 2 -
Readings along the western part of line 20S are unreliable because
of the presence of a power line.
Eight conductive zones have been defined by the survey. They are des
ignated by the letters "A" to "H" on the accompanying map. The amplitude
of the anomalies varies greatly, but the character is always the same
with a quadrature which varies sympathetically with the in-phase.
This is indicative of weak to moderate conductivity, either overburden-
related or of shear type.
SELF-POTENTIAL SURVEY
The self-potential survey was carried out using a fixed electrode and
a moving electrode connected by a cable which was unreeled as the survey
progressed along each line. The electrodes were standard porous pots
containing saturated copper sulphate solution. The potential was meas
ured using a Beckmann digital voltmeter with a sensitivity of * l milli
volt and an input impedance of 18 megohms. Line-to-line correction
was based on the assumption that a large body of water such as the
Moira River which crosses all the lines will be at a constant potential.
Points on the immediate water's edge were assigned an arbitrary potential
of zero. The results are plotted on the map in profile form. Negative
peaks are anomalies.
There are four SP anomalies, designated l to 4 on the map. No. l is
the strongest and it corresponds with VLF conductor E. It is paralleled
to the west by a second anomaly, no. 2, which may be the results of
random fluctuation superimposed on the down-dip "tail" of anomaly 1.
- 3 -
Anomaly no. 3 is rather weak. It lies on the southward strike extension
of VLF conductor F. Anomaly 4 is also weak. It does not coincide with
a VLF conductor, but it does appear to be related to the main Ackerman
gold-bearing vein.
CONCLUSIONS AND RECOMMENDATIONS
The SP survey has clearly responded to gold-arsenopyrite-quartz vein
mineralization and is therefore an important tool in exploration in the
area. Two new targets have been located by this survey which warrant
drilling. SP anomaly 1/VLF conductor E may be a sulphide-rich zone
and should be drilled. While VLF anomaly F appears to have been tested
by an old drill hole, the more important SP anomaly 3 has not been
tested and should be drilled.
