INTRODUCTION

Subsequent to initial geological investigation, the Pocket Pond

property underwent a geophysical exploration program during the Spring

of 1972. The program consisted of complete Radem (Vlf) E.M. and

magnetic coverage coupled with considerable coverage with the

horizontal loop E.M. method over the areas of greatest interest. As

a result of geophysical and preliminary geological work, a diamond

drilling program was initiated to delineate several targets. This

report summarizes the results of the geophysical surveys and their

correlation to geological features. Technical data is presented as an

appendix to the report in the form of a "Technical Data Statement".


2.

CONCLUSIONS

As a result of the performance of the above mentioned surveys,

fourteen distinct Radem (VLF) anomalies were discovered, ten of which

were confirmed by the Horizontal Loop survey. Of these latter anomalies,

five were tested by diamond drilling and in each case significant

quantities of sulfide material were encountered. A sixth anomaly had

been drilled by Noranda Mines Ltd. in 1966. In addition to the electro

magnetic conductors, seven maôr magnetic anomalies were located. These

appear to be related to pyrrhotite concentrations associated with the

conductors, mafic intrusive rocks, and magnetic oxide facies iron

formation.

RECOMMENDATIONS

In light of the good correlation between the electromagnetic

conductors located and the sulfide material encountered by diamond

rolling to date, it is recommended that any contemplated further

drilling programs include plans to test those electromagnetic conductors

as yet untested, vith priority to be given to E.M. anomalies H14, R4

and R7. In addition, it is suggested that detailed geological mapping'

be undertaken to determine the stratigraphic and structural control

of the conductors and sulfide occurrences.


GENERAL GEOLOGY

The Pocket Pond property straddles a major contact between acidic

and mafic lithologies. The former, represented by quartz-feldspar-

biotite schists represent sedimentary and/or tuffaceous units. The

latter, in some locations, has the appearance of massive andesite

or basalt while closely related phases have the appearance of horn

blende gabbro and diorite. Structurally, the property lies on the

north limb of an easterly plunging antiform. The units strike

approximately 2900 in the property area while dips are variable to the

north. Sulfide occurrences in some respects appear to be related to

acid-mafic transitions in lithology.

THE RADEM (VLF) SURVEY

Numerous dip angle crossovers were located during the course of

the survey and the major ones have been correlated and labelled as

conductors RI through R14 and are represented on an enclosed map. In

general, the crossovers are well defined and likely represent accumu

lations of sulfides or graphite in parallel zones. A few crossovers

of broad extent and poor resolution are likely due to conductive

overburden and are not considered in the report. The major anomalies

and their features are summarized in Table 1.


THE HORIZONTAL LOOP SURVEY

The results of this survey, depicted on an enclosed plan, more or

less confirm the existence of many of the conductors outlined by the

Had em method. Labelled HI through H10, these anomalies are referred to

in Table 1. The mean ratio of in-phase to quadrature response (l/Q) is

quoted as a relative estimate of conductivity thickness for the conductor.

THE MAGNETIC SURVEY

Seven major magnetic anomalies (Ml through M6) vere encountered

(see magnetic plan). In addition to those anomalies which are

directly correlated to E.M. conductors, anomaly M2 is tentatively

explained as representing a magnetic oxide facies iron formation.

Magnetic anomalies M3 and M? likely represents the western extension

of a mafic intrusive body.
