Douglas 2-80

INTRODUCTION

The property consists of 4 contiguous unpatented mining

claims numbered P-584843-P-584845 inclusive and P-586479. They are situated in the extreme southeast corner of Douglas Township.

The claim group is located approximately 18 miles southeast of Timmins, Ontario.

ACCESS

The property is reached via the Langmuir Mine road south of

South Porcupine, Ontario. Near the Croteau River a bush road is

taken to the southwest for 16 miles to the Fallon and Cleaver

Township line.

Final access is by foot along township line to the property which is \\ miles west from the road.

TOPOGRAPHY

The property is one of low relief with elevations ranging

between 1000 to 1075 feet above sea level. Open, flat lying,

swamp and grassy lowland areas mainly occupy creek flood plains.

Creeks are fast flowing and supply good drainage into Forks Creek.

Although spruce is the most abundant tree type found there

are also lesser amounts of birch, poplar, pine and cedar.

LINECUTTING

A base line 3200 feet long was cut on an azimuth of N60OW

from a point near bend in Forks Creek along Douglas, Fallon

Township line. Travers lines were cut normal to the base line at

400 foot intervals. A tie line at 24+00 south was cut to provide

additional control for the grid. The base line, tie line, and

traverse lines were all chained and picketed at 100 foot intervals

- 2 -

In all, 5.7 miles of line was cut, chained and picketed by Mike Wabano, linecutter, of Timmins, Ontario in the period March 27 - April 7, 1981.

MAGNETIC SURVEY

1) Assessment Data.

The instrument used was a McPhar M-700 Fluxgate Magnetometer. Base readings were taken along the base line and all readings were then adjusted relative to the base readings. Readings were taken at the base control stations at periodic intervals to discern day-to-day and diuranl drift. Any changes noted in the magnetic intensity were then applied as factors and progressive adjustments were made to each reading taken during that specific period of time.

Some 285 stations were read by Sigouin and Hussey, contractors, of Timmins, Ontario in the period June 8-10, 1981.

2) Magnetic Results.

The results of the magnetic survey are shown on prints accompanying this report.

Geological mapping has shown the property to be underlain by basic metavolcanic rocks (andesite) intruded by mafic rocks (olivine diabase).

One zone of negative magnetics was located by the survey. It traverses the property from 4+00 south on line 12 east to 8+00 south on line 20 west. Outcrops of olivine diabase have been found which correspond with this magnetic feature.

The area of higher magnetics along line 8 east may suggest that the line is parallel to a north trending diabase dyke.

No other magnetic anomalies of significance are present on the claim group.

H.E.M. SURVEY

1) Assessment Data.

The instrument used was an Apex MaxMin II horizontal loop

unit.

The instrument consists of a transmitting coil and a receiv ing coil connected by a reference cable either 200, 300, 400 or 600 feet in length.

The transmitting coil produces a primary electromagnetic field (e.m.f.) at either 111, 222, 444, 888, 1777 Hz which is capable of inducing a current within a conductive body. This current in turn produces its own e.m.f. which is termed the "secondary". The receiving coil measures the total intensity of the primary e.m.f. plus any resultant secondary e.m.f. It also breaks the received signal down to an in-phase component and quadrature component by means of the reference cable.

The two coils are used as an in-line system traversing across the presumed geological strike. If the two coils straddle a con ductor, the primary and resultant secondary field oppose each other causing a decrease in total field strength of a negative reading. In shallow overburden, a positive shoulder will occur when both coils are just off to one side of the conductor.

An indication of the conductivity of the body can be obtained by measuring the ratio of the in-phase to the out-of-phase. As the conductivity of the body decreases the stronger the out-of- phase component will be.

The range of penetration of the primary field is normally considered to be approximately one-half the coil separation; how ever, other factors such as conductive overburden and topography must also be taken into consideration.

Some 203 readings at each frequency were taken contemporan eously with the magnetic work by Sigouin and Hussey.

2) H.E.M. Results.

The results of the H.E.M. survey are shown on prints accomp anying this report.

One weak two line conductor was located. There is some suggestion that it correlates with a very slight magnetic ex pression (50 gammas).

CONCLUSION

Due to the isolated nature of this conductor more closely spaced detail E.M. work should be done, i.e. lines 2W, 00, 2E, 4E and 6E should be read across conductor with vertical loop unit. When the zone has been defined a drill hole is recommended to determine cause of conductivity.
