INTRODUCTION

This report describes a preliminary exploration program carried out by Complex Minerals Corp.

on the Zigzag Lake lithium prospect in the summer of 1997. The purpose of the program was

(1) to determine if geophysical surveys would be of use in locating further occurrences of

spodumene-bearing pegmatite in the area, and (2) to carry out a preliminary geological

reconnaissance of the main pegmatite ocurrences to assess whether mechanical stripping would

be of use in more fully defining known zones.

PROPERTY, LOCATION, ACCESS

The property consists of a single claim TB 1207190, comprising six claim units. The claim is

held by Nolan Cox of Beardmore. Complex Minerals Corp. holds an option on the property.

The property is located at approximately 50 027' north, 88 020' west, about 55 km east of

Armstrong. Access to the property during earlier exploration programs in the 1950's was by

a winter road running north from Ferland Station on the CNR northern line. Large parts of this

winter road are still negotiable by four-wheel drive vehicles. At the time the present property

was staked in 1996, access was possible by following logging roads eastwards from Armstrong,

connecting with the old winter road. However, during 1997 this access route was found to be

impractical owing to removal of culverts by the MNR. It was necessary to fly to the property

using a float-equipped light aircraft.

HISTORY AND PREVIOUS WORK

The Zigzag Lake lithium deposit was discovered in 1956 and was explored during 1957 and

1958 by Dempster Explorations Ltd. Mapping, trenching, manual stripping and channel

sampling were carried out. Although Dempster Explorations drilled several other lithium

prospects in the area, no drilling appears to have been carried out at Zigzag Lake, despite good

surface results. No exploration appears to have been carried out since that time.

1997 EXPLORATION PROGRAM

After locating the property, a 600 metre base line was laid out at 076 0 , along the axis of the

main lithium zones. Cross lines 150 metres long were cut at 50 metre intervals, for a total of

-2-

2.55 km of line cutting. The grid was surveyed using an EDA Omni Plus system, which

combines total field magnetometer, vertical gradiometer, and a VLF receiver, which was tuned

to transmitter NAA (Cutler, Maine). A recording base station provided diurnal correction.

Results were dumped to a portable computer and were subsequently processed by the writer

using Geosoft software.

A geological reconnaissance was carried out using the geophysical grid. Only outcrops,

stripped areas and trenches along the main pegmatite zones were mapped. Time did not permit

complete geological mapping.

The field crew consisted of Dusan Dmitrovic, mining technician and Arthur Gladu, line cutter

and field assistant. They spent four days of the property, from August lith to August 14th,

1QQ7

GEOPHYSICAL SURVEY RESULTS

The geophysical survey results are presented on seven maps at a scale of 1:1250, namely: total

field magnetic postings, total field magnetic contours, vertical gradient postings, vertical gradient

profiles, VLF in-phase and quadrature postings, VLF in-phase and quadrature profiles, and

Fraser filtered VLF in-phase.

Three conductors are apparent on the VLF survey. They have been labelled A, B and C on the

VLF profile map. All are of low amplitude and have strongly sympathetic quadrature, indicating

low conductivity. They may be caused by shear zones or zones of disseminated sulphides in the

volcanics. Conductor B coincides with a low north-facing cliff, and may be topographic in

origin.

The magnetic survey reveals a strong positive anomaly, up to 1000 nT in amplitude, extending

from 150E/45N to 500E/15N. It lies somewhat to the north of the spodumene-bearing

pegmatites, in the area of mafic volcanics. It is unexplained. A second, much weaker magnetic

anomaly coincides roughly with VLF conductor A.

-3-

The spodumene-bearing pegmatites show no geophysical response to VLF, total field magnetics,

or vertical magnetic gradient.

GEOLOGY

Three rock types are present in the grid area: mafic volcanics, granite, and pegmatite. The

mafic volcanics are fine-grained, dark grey and massive to schistose. They are metamorphosed

to amphibolite facies, perhaps by the thermal effects of the intrusive granite, and lack the

greenish colour of most mafic metavolcanics in the region.

The granite is pink in colour, coarse-grained and very massive. It is composed of alkali

feldspar, quartz and biotite. Only minor muscovite is present.

The pegmatites form a series of dykes along the base line of the grid. In their central portions,

they are extremely coarse-grained, with elongated crystals of pale green spodumene up to 25 cm

long, crysatls of pink and white feldspar up to 10 cm across, and books of muscovite up to 5

cm across. The interstices between these very large crystals are filled with a finer-grained

assemblage of quartz and feldspar with minor muscovite. In a general way, the marginal parts

of the pegmatite dykes are finer-grained than the centres.

The pegmatite dykes are up to at least 20 metres wide at the widest point. However, many of

the stripped areas are now somewhat overgrown and some of the trenches are filled with forest

litter, so that it is no longer possible to follow the forms of the dykes in detail. The high

spodumene contents of up to 25 o reported by Dempster Explorations Ltd. are substantiated by

visual inspection, and appear to be consistent along the lengths of the dykes.

CONCLUSIONS AND RECOMMENDATIONS

The conclusions that can be drawn from this brief program are as follows. Firstly, geophysical

surveys will not be of use in delimiting any extensions of the spodumene-bearing dyke system.

Secondly, the main group of dykes occurs in an area of high ground with shallow overburden.

Mechanical stripping will be an extremely effective way of fully delimiting the mineralized

zones.

-4 -

It is recommended that a program of stripping be carried out on the main dyke system along the

base line. The dykes should then be sampled using channel samples taken with a diamond saw.

A provisional budget is as follows:

Backhoe, 80 hours @ S857hour S 6,800

Prospector, 12 days @ SlSO/day 1,800
