The claims lie in the Timmins area. District of Cochrane and fall within the Porcupine Mining Division of Ontario.
LOCATION
The property is situated roughly 20 kilometers southwest of the City of Timmins in Bristol Township; NTS 42 A (81 0 30 ( - 48 023') .
Access to all portions of the claims is excellent as the northern property boundary lies along Highway 101.
PROPERTY DESCRIPTION
This group of mining claims is composed of twenty three contiguous, patented claims and is held jointly by Crow Geological Services Inc. and it's co-owners. The owners have been granted both surface and mining rights. In addition, the registered holders hold title to all timber rights other than pine (granted in 1949).
Records indicate that the claims have been patented since 1918 and were held continuously by Spina Porcupine Mines Ltd. and Havelock Energy fc Resources until the claims were acquired by the present owners.
The property consists of the following patented mining claims:

ASSET
The claims lie just southwest of the prolifically mineralized Timmins Gold Camp where a total of almost 58,000,000 ounces of gold has been produced to the end of 1988 from the time of discovery of gold in Timmins in 1909. Total tons milled to this date equals roughly 329,000,000 tons from mineralized quart z-ankerite veins averaging about 0.254 opt gold. While a total of 51 mines have operated at one time of another since 1910, the majority of this production, however, has been from the Hollinger, Mcintyre and Dome Mines.
Most of the past and present producing mines in the area were found and developed during the period from 1909 to 1940 and virtually all of the deposits were found during the first 10 years of extensive exploration by prospecting techniques. Prospecting in the Timmins area, therefore, has amounted to the discovery of about 861? of the gold recovered in this camp. In recent years exploration activity seems to have been focused on a re-examination of the old past producers for additional reserves both at depth and along strike. One such example is Placer Dome's activity at the old Paymaster Mine where new mineralization has been outlined as a result of underground diamond drilling.
While the claims lie outside of the cluster of gold mines centered around Timmins, the property straddles the interpreted western extension of the Porcupine-Destor fault, in which all gold deposits in the Timmins area are at least spatially related to. The mineral potential of the property lies entirely in its strategic location to this structure (referred to as the Bristol fault in the area of the claims).
At least one mineral occurrence has been located within the claims, however details of the discovery are lacking in the public records. No follow up on the surface showing took place in subsequent years as exploration on the property appears to have been confined to only work carried out in 1941. Since the patenting of the claims, which covers a period of about 75 years, there is no mention of further field work on the claims. The closest mineralization outside of the property lies 0.6 kilometers east of the claim boundary. This property, now wholly owned by Holmer Gold Mines, has reported drill indicated reserves in the order of 400,000 tons averaging 0.15 opt gold within a mineral inventory of roughly 700,000 tons grading 0.12 opt gold. This deposit has been the subject of intensive exploration up to about the end of 1988, at which time the major mining company earning an interest in the property withdrew from
Page - 3
continuing further work. The presence of this gold zone is further indication that a mineralizing episode has affected the rocks in the vicinity of the Bristol Fault.
REGIONAL AND PROPERTY GEOLOGY
A large portion of the property is covered by swamp, which in turn is underlain by a thin layer of glacial derived overburden varying from 20 to 30 feet thick. The geology, therefore, is largely inferred from magnetic data and from regional surveys carried out by the Ontario Department of Mines survey geologists.
Ferguson (1957) described the geology of Bristol Township and his work has never been updated. Based on his interpretation, the claims are underlain by Archean clastic metasediments consisting of 'turbidite' like sequences of arenites and wackes cut by a swarm of northwest trending Proterozoic diabase dykes. The strike of the argillites is N75 0E and the dip is steeply north. A quartz-feldspar porphyry intrusive body lies along to the north of the northeastern edge of the claims.
Structurally, the property is centered on the Bristol Fault, a multiple set of parallel faults totalling roughly 500 feet in width. As mentioned previously this structure has been interpreted to be the western extension of the Porcupine - Destor Break in which all gold deposits in the Timmins area are spatially related to.
EXPLORATION HISTORY
Ferguson (1957) summarizes the sole period of exploration activity on the claims (see following page) . This work was carried out in 1941 by Spina Porcupine Mines Ltd. and consisted of prospecting, a magnetometer survey and seven short drill holes totalling 1,747 feet. Three of these holes tested a quartz vein carrying minor pyrite and arsenopyrite which was exposed over a strike length of 30 feet on the surface and at least 300 feet inferred from the results of the drill intersections. Similar vein material was apparently intersected in the drill holes but gold values were not made public, nor are there are records of the results of sampling the vein material on surface. One can only speculate that the quartz showing carried gold as the company considered the occurrence worthy of follow-up drilling. The exact drill collar locations are unknown however their approximate locations are indicated on Ferguson 1 s (1957) map No. 1957-7.
Of potential economic interest is the mention in the early records of a carbonate zone, in which the strike extension
Page - 4
was interpreted to cross onto the property along the western boundary of claim 4492. One 95 foot drill hole by Spina (Figure 4) failed to penetrate through the overburden. This carbonate zone was referred to as the Stanwell Oil St Gas zone, however nothing is known of the gold content of this occurrence.
The property has been idle since 1941. A recent airborne EM/MAG survey flown by the Ontario Government in 1988 did not indicate the presence of any iron formation or electromagnetic anomalies of any order.
MAGNETIC SURVEY
The magnetic survey was carried out using an Omni Plus proton magnetometer made by EDA Instruments Ltd. of Toronto. This instrument measures the total magnetic field with an accuracy of 0.1 nT over a sampling time of approximately 2.5 seconds. The sensor is mounted on a 2.4 metre long aluminum staff and held at arm's length, while the instrument is carried on the operator's shoulders. Date, time, line numbers, station numbers, and readings are stored in a solid-state memory during throughout each day's survey. Readings were taken at 12.5 metre intervals throughout the survey grid.
A base station was set up near the junction of the access road and Highway 101, approximately 500 metres north of the north-west corner of the grid. It was set to take and store readings at 30 second intervals throughout the course of the survey. Internal clocks in the base station and survey instrument were synchronized at the beginning of each day. At the end of each day, the survey instrument and the base station were connected to each other and a computer, and dumped. An internal program corrects the field readings for diurnal variation by interpolating between base station readings to arrive at a correction for the time at which each field reading was taken.
It is necessary to select an arbitrary magnetic field for the base station, against which all base station readings are normalized. The value of 59,000 nT was used, which is approximately 400 nT higher than the mean base station reading during the course of the survey. Therefore, approximately 400 nT should be subtracted from all readings of the magnetic survey to obtain their "true" values.
The magnetic survey data were processed using software from Geosoft Inc. of Toronto. Three maps are presented: postings (i.e. diurnally corrected field readings) rounded to the nearest l nT; profiles, at a scale of l cm = 100 nT; and contours. The contours were generated by gridding the data on a 4 metre grid, and smoothing the grid with three passes
Page - 5
of a "Banning" 3x3 filter. Haps are at a scale of 1:2,000.
VLF-EH SURVEY
The VLF-electromagnetic survey was carried out concurrently with the magnetic survey, using the same EDA Omni Plus instrument. A VLF sensor pack is carried on the operator's back, and readings are taken concurrently with the magnetic readings. Three orthogonal coils measure in-phase and out- of-phase field strengths simultaneously, and a tilt meter measures the tilt of the instrument. This allows an internal program to calculate the in-phase (tangent of the tilt angle of the electromagnetic field, in percent), and resultant quadrature (also in percent). Also recorded are total field strength, and field direction (measured from the direction in which the operator is facing, which is assumed to be along the survey line). These data are not normally used for interpreting the survey results. The VLF data are dumped and stored at the end of each day in the same way as the magnetic survey results, but without correction.
The VLF survey data are presented in three maps at a scale of 1:2,000: postings, showing the in-phase and quadrature readings rounded to the nearest llr; profiles, at a scale of l cm s 103?, reflecting the low amplitude of the anomalies on the property; and Fraser filtered in-phase data. The Fraser filtered data were gridded and contoured in the same way as the magnetic survey results. The unusually close contour interval of 2 units was used, in order to show the weakly conductive trends that are present.
HORIZONTAL LOOP E.H. SURVEY
The horizontal loop electromagnetic survey was carried out using a Naxmin II system, manufactured by Apex Parametrics Ltd. of Uxbridge, Ontario. Coil separation was 100 metres, and was maintained by having the rear (transmitter) coil aligned against a measured mark on the cable, while the lead (receiver) coil was positioned at the appropriate picket. This method allows constant coil separation in area of subdued topography, which is important in the production of high quality data. Readings were taken at two frequencies: 444 Hz and 1777 Hz. Station interval was 25 metres. Line 1300W was surveyed using four frequencies: 222 Hz, 444 Hz, 1777 Hz and 3555 Hz. The topography across the survey grid is extremely flat, and it was not necessary to tilt the coils to maintain coplanarity.
The horizontal loop readings were acquired manually, and then entered on a computer to allow processing and map generation using Geosoft programs. Four maps were produced:
Page - 6
postings and profiles, each for 444 Hz and 1777 Hz. The profiles use a scale of l cm = 5 tr, again reflecting the resistive background on the property. Also, stacked profiles of all four frequencies, plus VLF and magnetic data, are given on a separate plot for line 1300W.
Regular calibration was carried out of the instrument, to guard against progressive phase mixing, which is one of the main causes of poor quality survey data with the Maxmin series of instruments. The effects of this are seen in occasional abrupt shifts in the background level of the in- phase readings from one line to the next.
SURVEY RESULTS
On the magnetic survey, the most prominent feature is a series of diabase dykes, belonging to the Matachewan dyke swarm. These are expressed as a series of positive anomalies, up to a maximum of 1200 nT above background. They are labelled A to 6 on the Compilation Map. All the dykes either terminate or show an abrupt change of direction in the immediate vicinity of the base line. This feature strongly suggests a fault, shear, or similar structural feature running across the grid. It is emphasized that any such structure is likely to be much older than the dykes, and has not offset them; instead the fractures controlling dyke emplacement have interacted with a pre-existing structure to produce the irregular pattern.
The single magnetic peak at 200E/015N is shown on the compilation map as being the offset end of dyke F. However, since it is only present on a single line, there is no confirmation for this. Since this anomaly lies on the interpreted east-west fault (see below), it should be considered as a possible target for further investigation.
Away from the diabase dykes, the magnetic pattern shows only a weak relief in the 20-50 nT range, with insufficient texture to infer any structural pattern. This is typical of areas underlain mainly by clastic metasediments. There are only two features that stand out: (1) at the north ends of lines 200W to 500W, there is a broad, weak magnetic high, up to a maximum of 50 nT above background, suggesting that this area might be underlain by mafic volcanics; (2) along and just north of the base line, from line O to line 400W, is a linear magnetic discontinuity with an amplitude of 10-20 nT. This latter feature coincides with the inferred fault, and may be an expression of it.
The VLF survey shows fifteen separate conductive zones, all with low to moderate amplitude. On the compilation map, these are divided into those with neutral to reverse quadrature responses (possible or probable bedrock
Page - 7
conductors) and those with sympathetic quadrature responses (i.e. in the same sense as the in-phase), which are considered to be probable overburden responses. There are 8 probable overburden conductors. Of the conductors with neutral to reverse quadrature responses, five (V2, V3, V5, V7, Vll) are broad, poorly defined anomalies suggestive of deep overburden troughs rather than surface swamps.
There are three VLF anomalies which are sufficiently sharply defined to be classed as probable bedrock anomalies. Anomaly V8 is the longest and strongest of these, extending from line 200E to line 500W, with in-phase amplitudes of up to 251;. It lies to the south of the interpreted fault along the base line. Anomaly V14 is also sharply defined, but weak, with in-phase amplitudes up to 10*r (possibly higher on line 300E, where the profile is truncated by the end of the line. Anomaly V15 appears to be sharply defined, but it lies only on line 600E in the extreme corner of the survey grid, and has not been fully defined.
The horizontal loop survey indicates four extremely weak conductive responses, labelled Hi to H4 on the compilation map. Of these, only anomaly H3, which coincides with VLF conductor V8 on lines 300W and 400W. It appears to be a bedrock feature with a conductance of 1-2 mhos, at a depth of around 80 metres. However, the response is so weak that conventional "thin-dyke" models are not properly applicable. Because it coincides with a reasonably well-defined VLF anomaly, which cannot be caused by a source 80 metres deep, it is inferred to be caused by a shear structure or other weakly conductive body, at shallower depth. Such a structure branching off a major fault zone known to be associated with gold mineralization elsewhere in the region should be regarded as an important target for gold mineralization.
Horizontal loop conductors HI, H2 and H4 are all too weak to apply thin-dyke interpretive curves to. It is likely that they are caused by overburden-filled troughs. However, since conductors H2 and H4 (along with their more or less coincident VLF conductors V3 and Vll) lie on or adjacent to the interpreted east-west fault, they should be further investigated as being areas of possibly slightly enhanced conductivity in the fault zone.
CONCLUSIONS
The geophysical survey has indicated two primary targets: (1) conductor V8/H3, which should definitely be tested as a potential mineralized shear branching off the fault zone; and (2) the west end of conductor Vll, which coincides with a magnetic anomaly on line 200E.
Page - 8
The survey has also indicated three secondary targets: (1) the west end of conductor V14, a probable bedrock conductor away from the fault; (2) conductor V3/H2; and (3) conductor V11/H4. These latter two anomalies are weak and questionable conductive responses, but appear to be directly coincident with the fault.
Finally, conductor V15, which lies at the extreme north-east corner of the surveyed area, should be more fully defined by additional surveying.
