REPORT ON THE
AIRBORNE GEOPHYSICAL SURVEY
ON THK PROPERTY OF
SKEAD HOLDING l,TD.
MANN TOWNSHIP, ONTARIO
INTRODUCTION
On December 33 to December 34, 3987 a n a irborne geophysical survey was carried out on the property of Skead Ho3ding Ltd. in Mann Township, Ontario. Magnetic and VLF-e3ectromagnetic data was collected by the airborne division of H. Ferderber
Geophysics Ltd. The survey was f 3 own from base at Ne33ie Lake- Jroquois Fa]3 s, Ontario. A total of 33.22 mi3es of data was co3 3 ected.
The magnetic survey provides information which he3ps define underlying geological structures and identifies any potential
economic concentrations from magnetic variations in accessory magnetic minerals. The VI,F-e3 ectromagneti c survey outlines conductive zones which may represent, shear zones and/or
metallic sulphide deposits containing gold mineralization.
3.0CATTON AND ACCESS
The Skead Holding Ltd. property is comprised of 6 claims in
Mann Township, Porcupine Mining Division, Ontario. The claims
cover approximately 96 hectares in the northeast corner of the township, are registered with the Ontario Mining Recorder's Office in Timmins and are 3isted be3ow.

The property is located approximately 21.7 km (13 miles) southof the town of Cochrane, 26.7 km (16 miles) northwest of the
town of Iroquois Palls and 10 km (6 miles) west of the villageof Potter.
Access to the property is easily obtained from the village ofPotter which lies along Highway 11 between Cochrane andIroquois Falls. By tciking a secondary road due west from
Potter for about five and a quarter miles, continuing westward
at all junctions, a southwest bend in the road is reached. Thecentral part of the eastern boundary of the property lies aboutone quarter mile further west of the bend. The road continues
westward, traversing the property.
A small lake lies in the northeast corner of the property. Theproperty appears to be vegetated by deciduous trees in thenorth and coniferous trees in the south. Topographic relief islow and the terrain is relative dry.

A Ni-Cu occurrence lies about one mile west-northwest of the northwest corner of t lie property, along strike of the metamorphosed ultramafic rocks. About three and one half miles west of the northern part of the property lies a Ni-Cu-Pd occurrence which appears to be along strike of the geology of the claim group.
INSTKUMENTAT]ON AND SURVEY .METHODS
The survey was completed using a 1972 Cessna 172, fixed-wing aircraft, call letters CF-EWK, owned and operated by H. Ferderber Geophysics Ltd. The pilot and navigator/operator were Y. Saucier and M. Caron, respectively, of Val d'Or. Geophysical sensors were mounted in modified wing tips. The geophysical, navigation and data aquisition systems are described below.
Ma g netometer
The magnetometer used was a GEM Systems GSM-11, high sensitivity airborne proton (Overhauser) magnetometer. The instrument continuously measures the Earth's magnetic field at a 0.01 gamma sensitivity for l reading per second or 0.05 gamma to 10 readings per second at a 0.1 gamma absolute accuracy. The analog output i s on 3 channels, from l to 10,000 gammas full scale.

yi.F-KM System
A Her?, Tot.em 2A VLF-KM System was used. To measure the change an the total field and jn the vertical quadrature fjeld on two frequencies simultaneously, with an accuracy of l?,. The primary transmitting station of Cutler Maine, (NAA) frequency 24.0 KHz was employed in survey.
Radar A11 i me t c^r
The ground clearance was measured with a King 10/10 A radar altimeter. The survey was flown at a mean clearance of 300 feet with the altimeter producing an accuracy of 51 (15 feet) at this altit ut e.
Tracking Camera an d Vi djso ̂ Ce ntre
A RCA TC-200 colour video camera and Galaxy 200 video centre was used to record the flight path on standard VHS type video tapes. Manual fiducials were indicated on the picture frames for reference with the digital printout. Flight path recovery was aided using a Panasonic Colour Video Monitor-S1300 and Video Cassette Recorder AG-2500.

The aeromagnetic data was corrected for diurnal variations by using a base line as reference. The data was then reduced to a base level of 58,000 gammas, contoured at ]00, 500 and ]000 gamma intervals and presented on Map MG-1 ,
A base value was determined for the VLF-KM data and the change in the total field strength as a percentage of the base value was calculated. The values were plotted on map EM-1. The positive values were contoured at intervals of 2%. The conductor axes were determined and labelled A, B, C, etc. No priority was attached to the labelling system.

Magnetic Survey Map MG -l
The survey outlined two distinct northwest trending magnetic anomalous zones traversing the property. A magnetic high anomalous zone located in the northern half of the property has a steep magnetic gradient, magnetic values in excess of 4000 gammas above background and overlies rocks indicated as being metamorphosed ultramafics. A magnetic low anomalous zone on the southern half of the property has a shallow magnetic gradient and overlies rocks indicated as being intermediate to mafic metavol cani cs. The contact between the two rock units has a northwest trend and traverses the central part of the property.

Further work is warranted on the property especially in the areas of the above mentioned conductor and the assumed position of the geologic contact determined by the magnetic data.
An exploration program of ground geophysics should be undertaken. A combined gradient/total field magnetic survey and a horizontal loop-electromagnetic survey should be performed. Geophysical anomalies should then be tested by diamond drilling.
