INTRODUCTION

Walker Exploration Ltd. contracted to carry out a magnetic survey

over 4 mineral claims in the southwest sector of Sheraton Township, about

40 kilometers east of Timmins. The linecutting and chaining was done in

February 1985. The magnetic survey was made on April 3, 1985.

An EDA PPM 300 proton magnetometer was used for the survey, while

an EDA PPM 400 base station magnetometer was used for diurnal control. About

8.2 kilometers of line was surveyed.

SUMMARY

The magnetic survey suggests a north-south structure, likely diabase,

under heavy drift cover, and is likely a continuation of the same zone on

Grid SH3, one half mile to the north.

PROPERTY

The property covers the north h of Lot 10, Concession II in

Sheration Township. The 4 mineral claims are 822393-822396 inclusive.

Access is via the Gibson Lake road which crosses the claims. The Gibson Lake

road goes south from Highway 101, about 4 kilometers east of Night Hawk Lake.

The group is about 22 kilometers by road south of Highway 101.

PREVIOUS WORK

Cominco carried out airborne and ground geophysics to the north

of this group. No assessment work has been recorded on these claims.

GEOLOGY

Precambrian basic volcanics underlie the Sheraton Township area.

Some north-south diabase dykes are in the southeast section of the township.

The westerly part of the township has heavy drift cover.

SURVEY METHOD

The magnetic survey was performed with EDA PPM 300 proton magnet

ometers, measuring total field to 0.1 gammas. Diurnal control was made by

using an EDA PPM 400 base station magnetometer, located on the Gibson Lake

road, to the north of the grid. Other grids on this project are tied into

this common base station.

The field magnetometer and base station magnetometer have solid

state memory for storage of values and locations of stations read. The

instruments have built in clocks which are synchronized each day. The units

are plugged together each evening and the built in computer programme in

the base station allows for automatic diurnal corrections. Corrected data

was stored on cassette of an HP85 computer.

- 3 -

Observations were made at 25 meter stations on lines at 125 meter

spacing. Values are plotted on a plan at a scale of 1:5000. Contours of

values are plotted on a separate sheet.

SURVEY RESULTS

A north-south zone of higher magnetics occurs along Line 250W,

with the rest of the grid fairly flat.

CONCLUSIONS

The north-south structure is likely a diabase under heavy over

burden. The relatively flat area adjoining to the west also indicates

heavy cover.
