REGIONAL SETTING

The Astro Property 1 ies a1 ong the n~wthern boundary c~f the Tertiary-age White Lake Basin. This Tertiary volcanic-sedimentary c ~ ~ m p l e x is hc~st for two epittiermal gold deposits. The Dusty Mac Mine has prc~duced over 20,000 ounces of gilld during the period 1969 t13 1372 and is being actively explored. The Vault Property is currently being drill tested by the Inco and Seven Mile High Resources' Joint Venture with impressive results. Recent deep drilling has intersected gold grades to 0.31 uz/tiln gold over 28 feet and 0.23 oz/ton gold over 42 feet. Drill programs tc~ date have outlined a large epithermal gold bearing system over a surface area measuring 818 meters (2700 ft. 1 by 454 meters (1500 ft. 1 The deposit remains open along strike and to depth. Surface exposure uf mineralizati~~n is minimal due tu post ore faulting. There are presently twa drills on the Pruperty. The Vault Property is une c~f the more significant epithermal discoveries in southern British Citlumbia.

The Astro Prctperty lies immediately west of the Vault claims and is underlain by several units of the Tertiary-age Marron Formation. Vari~zus members of the Marron have been recognized as trachyandesite, trachyte and volcanic wackes.

Earlier district mapping by B.N. Church (Preliminary May 35, Geology of the Penticton Tertiary Outlier) has outlined several faults within the Astun claims that potentially could host epi thermal gold mineralization.

INTRODUCTION.

Between November 15th and 29th, 1989, Peter E. Walcott & Associates Limited carried out VLF electromagnetic and magnetic surveying over a property, located in the Penticton area of British Columbia, for Welcome North Mines Ltd.

The survey was carried out over north-south "chain arid compass" lines that were established by the geophysical crew from an east-west tie line, and that were chained at 25 metre intervals.

Measurements of the total intensity of the earth's magnetic field were taken together with readings of the vertical inphase and quadrature components of the VLF magnetic field using the navy station at Annapolis, Maryland as the VLF transmitter.

The progress of the survey was hampered by the rough terrain an the western extremity of the property.

The magnetic results are presented in profile and contour form on plan maps af the line grid, whereas the VLF results are presented as profile plots, and as contoured Fraser filter data.

PROPERTY, LOCATION & ACCESS.

The property, consisting of the Astro claims, is located in the Osoyoos Mining District of British Columbia.

The claims are situated straddling Hwy. 3 A some four kilometres west of its intersection with Hwy 97.

Access is obtained by the above highways from either Penticton or Okanagan Falls some 5 kilometres to the northeast and southeast respectively.

PURPOSE.

The purpose of the survey was to (1) satisfy assessment requirements and (2) to see if there might be any VLF electromagnetic anomalies indicative of weak narrow sulphide mineralization that could be associated with epithermal gold mineralization as on the adjoining Vault property to the east.

SURVEY SPECIFICATIONS.

The magnetic survey was carried out using an EDA Omni- Plus proton precession magnetometer, mankifactured by EDA Instruments Inc. of Metropolitan Toronto, Ontario. This instrument measures variations in the earth's magnetic intensity to an accuracy of plus or minus one gamma. Corrections for diurnal variations were made by comparison with readings obtained on a base magnetometer also manufactured by EDA.

The basic principle of any electromagnetic survey is when conductors are subjected to primary alternating fields

secondary magnetic fields are induced in them. Measurements of these secondary fields give indications as to the size, shape and conductivity of conductors. In ,the absence of conductors no secondary fields are obtained.

The VL,F electromagnetic survey was carried out using an EDA Omni-Plus System manufactured as described above. This unit makes use of the VLF transmitting stations operating for communication with submarines for its transmitted signal - the vertical antenna currents create concentric magnetic fields - and measures the vertical components of the secondary fields created as above. These measurements were made at 25 metre intervals along the grid lines.

In all some 61.2 kilometres of combined magnetic and VLF electromagnetic surveying were carried out.


PE!lY3R E. WALCOTlC & ASSOC. LTD.

DISCUSSION OF RESULTS.

The writer has contoured the data obtained at 25 metre intervals on lines 200 metres apart on a chain and compass survey with limited control to facilitate better presentation. However, the reader should be aware that this will create a strong directional bias in the data,

The magnetic survey exhibited the typical pattern expected from the underlying volcanics. Two areas of higher magnetic intensity can be readily seen on the plan and contour maps of the magnetic data in the northwestern and southwestern portions of the grid, associated with higher elevations, with the former in fault contact with the rocks to the south as evidenced by the line of cliffs.

Other faulting can be seen in generally ENE and NNW directions as best emphasized on the 1:20000 colour contour map- these directions are partially a product of t.he wide line spacing.

The VLF electromagnetic survey showed numerous conductors generally trending eastwards across the grid- partially or. wholly a product of the line spacing. The strorlger and more continuous of these are labelled conductors A through I1 on the contoured plan of the filtered VLF data. Cultural anomalies due to power lines and/or wire fences, as can be seen from the profile map, have not been classified as conductors.

Conductor axes have been extended mainly on the basis of the contoured filtered data. However individual axes could be connected differently in cases based on profile slope as per conductor H and the adjoining short conductor to the north. Closer spacing work could clarify these discrepancies.

e SUMMARY, CONCLUSIONS & RECOMMENDATIONS.

Between November 15th and 29th, 1988, Peter E. Walcatt a & Associates Limited undertook a reconnaissance VLF Ld electromagnetic and magnetic survey over a property, located in

the Penticton area of British Columbia, for Welcome North Mines Q Ltd.

The property lies to the immediate west of the Vault

F"t property where Inco Gold is planning to spend an additional 1.2

b million to further investigate a potential epithermal gold deposit.

i"" The surveys, carried out over widely spaced lines, kd indicated the presence of numorous VLF conductors whose causative

sources could be faults and/or weak sulphide mineralization.

P u As a result he recommends that (1) these anomalies be

investigated geologically ( 2 ) these anomalies he detailed at

P closer line spacing to confirm t h e i r strike lenghts and

b directions, and ( 3 ) soil sampling be undertaken in t h e i r vicinity before any nia jor coniniittlnent to the property is considered.
