ONTARIO
1. INTRODUCTION
On "behalf of Enertex Developments Inc., ground magnetic and
VLF electromagnetic surveys were conducted on ? claims in Shedden
Township, Sault Ste. Marie Mining Division, Ontario. The surveys
were carried out by E.M. Hall, Geophysical Technician, Toronto.
The following report comprises the observations and results of
these surveys. The presentation and interpretation of the data
are provided by Ulla M. Knowles, B.Se., #2206-201 Sherboume St.,
Toronto, Ontario.
2. LOCATION AND ACCESS
The property comprises seven (7) contiguous unpatented min
ing claims (SSM 809518 to SSM 80952*4- inclusive), recorded on Min
ing Claims Map No. M.l109. They are located as follows:
SSM 809518 - 809523 incl.j Con. IVi Lot 9...-....- 6 claims
SSM 809524: Con. IV? Lot 8........................ l claim
Totals 7 claims
The claims are located in the Sault Ste. Marie Mining Division of
Ontario. The property area is approximately 280 acres.
The property lies approximately ^ miles northwest of the town of Spanish located on Highway No. l?. Access to the property is provided by the Beckerton's Logging Road which departs to the north from Highway No. l? at a point 2.5 miles west of the town of Spanish. The logging road passes through the western end of the claim block.
3. HISTORY AND PREVIOUS WORK
The earliest exploration work on the copper showings known as the Black Lake Occurrence in Shedden Township, Ontario, is recorded in 1956. Sam Linton drilled ^ holes totalling 209 feet to test surface showings of chalcopyrite in quartz veins and as disseminations in diabase. No assays are recorded for these holes.
An 80-foot deep shaft has been sunk on the showingi however, no published record of the workings or production exists.
The property was staked by Gradore Mines Ltd. in 1966. Nine diamond drill holes totalling 3.15^ feet tested the surface showings. Assays for copper, silver and gold are recorded.
No additional exploration work is recorded on the property after 196?.
The property was mapped at a scale of l inch to 1/2 mile by J.A. Robertson of the Ontario Ministry of Natural Reso'.;r."es in 1977-
4. GENERAL GEOLOGY
The property is underlain predominantly by Early Precambrian
felsic intrusive rocks comprising granite, granite gneiss and
related rocks. Incorporation of older Keewatin metavolcanic and
metasedimentary rocks occurs in places. These mafic inclusions
are chloritized and amphibolitized. Early Precambrian post grani
tic porphyritic diabase dykes trend northeasterly in the southern
part of the claim group.
Nipissing diabase dykes trending north-northeasterly and west-
northwesterly occur throughout the claim group.
Although no faults are indicated in the area on OGS Map 2315
(J.A. Robertson, 1977)i northeast and northwest trending struc
tures are evident on air photographs of the general area.
5. ECONOMIC GEOLOGY
Chalcopyrite occurs in quartz veins and breccia zones asso
ciated with Nipissing diabase dykes and Early Precambrian mafic
rocks. It is also found as disseminations within both the diabase
and the mafic rocks. Pyrite is associated with the copper mineral
ization.
Diamond drilling by Gradore Mines Ltd. in 1966 intersected
copper mineralization as described above. The best two intersec
tions yielded the following results:
DDK No. Width #Cu
1 5*0 feet 1.4?
2 10.0 feet 0.?
Generally, copper assays yielded less than 0.^ Cu.
Trace amounts of gold up to 0.02 oz./ton were present i how
ever, silver Tvas absent.
6. GROUND GEOPHYSICAL SURVEYS
a. Introduction
Ground magnetic and electromagnetic surveys were carried out
over north-south cut lines *K)0 feet apart extending from an east-
west trending baseline. Magnetic readings were taken every 50 feet
along the lines with a Scintrex fluxgate magnetometer. Electromag
netic readings were taken with a Geonics EM-16 unit at 100-foot
stations along the cross lines.
The following observations are preliminary and subject to
re- evaluation and re- interpretation following geological mapping
of the claim block.
b. Magnetic Survey
The magnetic variation within the claim area is moderate.
Zones of increased magnetism are linear in character and most
likely are traces of Nipissing diabase dykes. These generally
trend northwesterly. In the western end of the grid between
Lines 8+OOW and 12+OOW, the linear magnetic highs terminate ab-
ruptly, possi"bly indicating a north-trending fault in this area.
An intense magnetic anomaly exists on Line *H-OOW at 21+OOS
to 22+OOS. There is a coincident weak VLF anomaly at this loca
tion.
c. VLF Electromagnetic Survey
Several VLF conductors of moderate strength occur in the grid
area.
Three main conductive zones are delineated. These appear to
follow topographical linears and probably represent water filled
shears or faults. They trend west-northwesterly, northeasterly
and north-northeasterly. The latter fault direction is rather
dubious due to the poor coupling between the transmitter and this
direction.
Additional isolated weak to moderate conductors occur across
the gridi however, further interpretation of these zones is not
attempted due to the lack of geological information over the
grid area.
A weak conductor coincident with a strong magnetic anomaly
occurs on Line *H-OOW at 21+50S. This anomaly warrants further
investigation.
7. CONCLUSIONS AND RECCOMENDATIONS
1. Preliminary interpretations of both the magnetic and VLF
electromagnetic surveys has indicated several dykes and major
structures across the grid areaj however, these require verifi
cation by geological mapping of the grid.
2. A coincident VLF electromagnetic and magnetic anomaly
occurs along Line in-OOW between 21+OOS and 22+OOS. This anomaly
warrants further investigation to determine its cause.
3. Previous diamond drilling by Gradore Mines Ltd. indicates
copper mineralization to occur in or associated with mafic rocks
of two ages namely, Early Precambrian unsubdivided metavolcanic
rocks and Nipissing diabase dykes. As the association is unclear,
detailed examination and sampling of exhisting pits exhibiting
the mineralization, is recommended. In addition, particular
attention should be given to delineating mafic metavolcanic
units incorporated in the granite across the grid area.
^ . The mafic metavolcanic units and the Nipissing diabase
dykes should be prospected in detail in search of additional
zones of copper mineralization.
5. A ground radiometric survey should be carried out over
the grid area in conjunction with the mapping survey to receive
an additional 20 days work credit/claim to hold the ground in
good standing.
