SUMMARY

The Savant Lake property consists of 46 contiguous unpatented mining

claims covering approximately 750 hectares. The claim group is located on the

southwest shore of Savant Lake in Poisson Township about 27.5 km northeast of

the town of Savant Lake, Ontario.

Geological mapping and rock sampling revealed that the property is

underlain by iron formation bearing-ferruginous metasediments and by lesser

arenaceous metasediments that have been folded about a northeasterly trending

synclinal axis and are locally faulted and sheared*

Reconnaissance prospecting within the claim group located a wide

northeasterly trending shear zone just west of Girard Island, in Savant Lake, that

may host significant gold mineralization. Gold has been found near the property

in similarly mineralized northeasterly trending shear zones at the One Pine Lake

showing and the Shoal occurrence. Although no significant gold values were

obtained from sampling of this zone in the current program, the structure

warrants further investigation along strike where it is covered by water.

A Phase II exploration program is proposed for the fall of 1987 that would

focus on the islands within the claim group to explore for mineralized shear zones.

This program would include chaining a grid, geological mapping, geochemical

sampling, a VLF electromagnetic survey, and a fluxgate magnetometer survey.

Also included in this program would be a fluxgate magnetometer survey of the

mainland cut line grid as the instrument used in the Phase I program could not

handle the steep magnetic gradient encountered.

Contingent upon favourable results in Phase H, a third winter phase is

proposed which would include diamond drilling of any prospective targets. At that

time the remainder of the property that is water covered would be covered by

VLF electromagnetic and fluxgate magnetometer surveys.

INTRODUCTION

This report, prepared by Derry, Michener, Booth i Wahl (DMBW) on behalf of McArthur Mills Explorations Ltd., summarizes the Phase I exploration

program carried out between June 16 and July 8, 1987 on the Savant Lake gold property located near the town of Savant Lake, Ontario. The program consisted

of linecutting, magnetometer and VLF electromagnetic surveys, geological mapping, geochemical sampling and reconnaissance prospecting.

Although no significant gold deposits have been found to date in the Savant Lake area, iron formation-hosted gold deposits are present to the east near Geraldton and to the north near Pickle Lake. Since the Savant Lake property is

underlain by similar rock types as found at these deposits, it has the potential to host significant gold mineralization.

PROPERTY LOCATION. DESCRIPTION AND ACCESS

The Savant Lake property is located in Poisson Township, Ontario, on the west shore of Savant Lake approximately 27.5 km north-northeast of the town of Savant Lake (Figure 1). The property consists of 46 contiguous staked claims

covering approximately 750 hectares (Figure 2, Map 87-76-03). The claims are as follows:

856329 - 956374 inclusive

The property extends westward from the west-central shore of Savant Lake, tying-on to the eastern boundary of the previously-staked claims at One Pine Lake, and northward to the north end of the peninsula projecting into Savant

Lake (Figure 2). The property is easily reached by boat via Savant Lake. Provincial Road 599 crosses northward through Mccubbin Township approximately 6.5 km west of the property. In the northeast corner of Mccubbin Township a

trail leads eastward from Provincial Road 599 to cabins on Savant Lake (Figure 1).

TOPOGRAPHY

The Savant Lake property is characterized by relatively flat topography.

The terrain averages 412.0 to 419.9 m above sea level (ASL) but locally reaches a

maximum of 460 m ASL. Glacial deposits are extensive, with moraine ridges

locally breaking the flat topography. The moraine between Whimbrel and Savant

Lakes separates the Savant Lake area into two drainage basins: the area east of

Whimbrel Lake drains northeastward whereas west of and including Whimbrel

Lake the drainage is westward. Rock exposure in the Savant Lake area is

generally sporadic and variable in amount but within the Savant Lake property the

outcrop exposure is very good.

EXPLORATION HISTORY

Collins (1910) conducted the first geological reconnaissance of the Savant

Lake area for the Geological Survey of Canada, who published the work on Map

993 at a scale of l inch to 4 miles. Moore (1928) studied the Savant Lake region

and published Ontario Department of Mines (ODM) Map 37j at a scale of l inch to

2 miles. Rittenhouse (1936) mapped Poisson, Mccubbin, Conant and Jutten

Townships and his work was compiled by Satterly (1941) on a map at a scale of

l inch to 1/2 mile. Skinner (1969) also mapped the area at a reconnaissance scale

of l inch to 4 miles. The Savant Lake area has been included in a l inch to 4 mile

compilation map of the Sioux Lookout-Armstrong region (ODM Map 2442)

(Breaks, 1980).

The Savant Lake area was first prospected for gold at the turn of the

twentieth century. Extensive iron deposits were discovered west of Savant Lake

several years later. The McRae-Simmons Occurrence, the first significant gold

discovery in the Savant Lake area, was found in 1926 and is located on a small

island approximately l km southeast of the centre of Girard Island in Savant Lake.

At this occurrence, visible gold is associated with quartz in a vertically dipping

shear zone. Noranda optioned the property in 1926 and conducted considerable

test pitting and trenching, including the sinking of a 4.6 m shaft in the winter of

1926-1927. After several months of work, Noranda dropped its option.

During the 1940's Northern Canada Mines Limited carried out an

extensive exploration program in the Savant Lake area. This resulted in two gold

discoveries, the first being made in September 1940 on the east side of One Pine

Lake, immediately west of Savant Lake. Gold at this occurrence is associated

with a shear zone in which massive and euhedral pyrite layers are interbedded

with magnetite iron formation and greywacke. The shear zone contains

discontinuous quartz and minor carbonate veins, veinlets and stringers. Shortly

thereafter, a second gold occurrence was found approximately 1.6 km southwest

of One Pine Lake. Here, gold was found to be present in a series of narrow quartz

veins in iron formation-bearing metasediments. Northern Canada Mines drilled

the gold occurrence at One Pine Lake in 1941, putting down a total of 8 holes.

Algoma Steel Corporation Limited evaluated the iron potential of the iron

formation within a group of claims in the vicinity of One Pine Lake and Snowbird

Lake in 1966. Magnetometer and geological surveys were conducted over the

claims. Iron formation was found to make up no more than 1596 to 2096 of any

particular outcrop and the claims were allowed to lapse in 1971.

Morris Caddell staked a group of 74 claims on the west shore of the main

body of Savant Lake in February 1969. All claims expired in April 1970 but

12 were restaked. A magnetometer survey was conducted over the northern part

of the property between Savant Lake and Whimbrel Lake in July 1969. Based on

the geophysical survey, faulting was interpreted to be present in parts of the

property. Bond (1977), however, suggests that the persistence of the iron

formation contradicts this interpretation. An additional magnetometer survey

was conducted in 1971.

Noranda Exploration Company Limited carried out a combined ground

magnetic and electromagnetic survey on the northern part of Girard Island in

1971. Four anomalous zones were defined in the survey. A VLF-EM survey was

recommended as a follow-up program.

In the spring and summer of 1981 Stargazer Resources carried out a major

regional exploration program in the Savant Lake area including airborne and

ground magnetic, electromagnetic and VLF-EM surveys, geological mapping and

rock, soil and biogeochemical sampling. In winter of 1981-1982, a follow-up

program of trenching, rock geochemical sampling and diamond drilling was carried

out. The airborne geophysical survey included the present Savant Lake property

and one ground geophysical grid was located partly within the boundary of the

present property, covering three weak airborne EM anomalies near the small lake

in the northwest corner of the property.

In 1981, Ray Ramsay and Ram Petroleums Limited conducted ground

magnetic and VLF-EM surveys, geological mapping and prospecting within a claim

block south of One Pine Lake. The Shoal Occurrence was discovered at this time

in the southeast corner of the property. Ramsay and Ram Petroleums Limited

also carried out a 112 line km combined airborne magnetic and electromagnetic

survey from Savant Lake, south of One Pine Lake, west to Kashaweogama Lake.

A geological survey of the Shoal property was completed in 1982. Savant

Exploration Limited optioned the property and conducted a 7-hole diamond drill

program at the occurrence in 1984.

Abitibi-Price trenched, blasted and sampled the One Pine Lake

occurrence in June 1982. Of sixteen samples collected, the best assay was

0.120 oz. Au/ton with values in the remaining samples ranging from trace to 0.056

oz. Au/ton.

Norontex Exploration Limited cleared, sampled and mapped parts of the

trenches at the McRae-Simmons occurrence in June, 1982. Thirteen samples were

collected and assayed trace to 1.50 oz. Au/ton.

In October 1983, Ray Ramsay and Ram Petroleums Limited conducted a

geological mapping program on a group of claims southwest of One Pine Lake.

This property is believed to contain historic trenches related to the second gold

showing found by Northern Canada Mines Limited in 1940.

No further work has been recorded on the present property.

REGIONAL GEOLOGY

The rocks of the Savant Lake area are part of the Wabigoon Subprovince,

and are Archean in age with the exception of rare late Precambrian diabase

dykes. Detailed and reconnaissance mapping indicates that mafic to intermediate

metavolcanic rocks form the base of the Savant Lake sequence and are overlain

by metasedimentary and felsic to intermediate metavolcanic rocks. The entire

metavolcanic and metasedimentary sequence is apparently folded about a

northeast trending axial trace and is bounded by granitic batholiths (Bond, 1977)

(Figure 3).

The mafic to intermediate metavolcanic rocks at the base of the sequence

may be up to 9,000 m thick and the presence of abundant pillow structures in the

flows indicates that these rocks were deposited in a subaqueous environment. The

overlying felsic to intermediate metavolcanic rocks are predominantly pyroclastic

and may locally be up to 3,300 m thick. The metasedimentary rocks consist of

conglomerate overlain by greywacke, sandstone, siltstone and cherty beds. Iron

formation is present both as distinct units and as interbeds with the

metasediments (Bond, 1977).

Minor metamorphosed sills of gabbro and diorite intrude the metavolcanic

and metasedimentary rocks. The granitic batholiths bounding the metavolcanic-

metasedimentary sequence are predominantly foliated to gneissic trondhjemite,

granodiorite and locally quartz monzonite. Quartz and quartz-feldspar

porphyritic dykes and sills are included in this group of variably altered and

recrystallized intrusive rocks. Several massive, unmetamorphosed granodiorite

stocks, including the Wiggle Creek and Grebe Lake stocks, intrude the

metavolcanic and metasedimentary rocks. Late Precambrian diabase dykes are

scarce in the area but locally intrude the granitic batholith east of Savant Lake.

The volcanic, sedimentary, gabbroic and dioritic rocks have been

regionally metamorphosed to greenschist facies. Near the contact with larger

granitic bodies, the rocks have been metamorphosed to amphibolite facies

(Bond, 1977).

The metasedimentary and metavolcanic rocks have been faulted and

folded. Both faults and fold axes have a northeasterly trend. Bond (1977)

concludes that the Savant Lake area is complexly folded rather than dominated by

a single synclinal fold as suggested by earlier workers. Minor folds are most often

observed in the iron formation within the metasediments.

CURRENT PROGRAM

The Phase I exploration program was carried out as proposed by DMBW in

their report by Trinder and Taylor (1987). The program consisted of establishing a

cut line grid, magnetical and VLF electromagnetic surveys, geological mapping,

geochemical sampling and reconnaissance prospecting.

Surface work was controlled by a cut line grid with the baseline and tie

lines trending 0350. Lines were cut perpendicular at 100 m intervals and stations

were chained and picketed every 25 m (Figure 4, Map 87-76-03).

Magnetometer and VLF electromagnetic surveys were performed to

locate possible favourable conductive and magnetic structures which may host

significant gold mineralization on the property. A detailed report of these

surveys is given in the geophysics section of this report.

Geological mapping was done on a 1:5,000 scale and results are shown on

Map 87-76-01 (in back pocket) and in simplified form on Figure 5. A total of 134

rock samples were taken from the cut line grid area and analyzed for gold using

conventional fire assay methods. Sample locations are given on Map 87-76-01 and

results are listed in Appendix II.

Following the geophysical and geological surveys of the cut line grid area,

a short two-day reconnaissance prospecting program of the remaining claims was

done. All shorelines of islands located within the claim group on Savant Lake

were walked and a total of 22 rock samples were taken. All 22 were analyzed for

gold and of these, 12 were also analyzed for silver. Sample locations are given on

Figure 4 and the assay results are listed in Appendix III.

PROPERTY GEOLOGY

Stratigraphy

The Savant Lake property is underlain mainly by ferruginous

metasediments with local interbedded arenaceous metasediments and

intermediate feldspar lapilli tuff. The complete sequence has been intruded by

later ultramafic dykes and is folded around a northeasterly trending synclinal

structure. Bedding of all metasedimentary units is fairly regular and thicker

individual units can be traced for 30 m or more along strike. Both the ferruginous

and arenaceous metasediments are of similar composition and texture, but are

distinguished on the presence or absence of magnetite as either discrete bands of

iron formation or as finely disseminated crystals. All rock units display weak to

moderate chloritic alteration suggesting regional metamorphism of lower

greenschist rank (Bond, 1977). Specific rock type descriptions are given in

Appendix I and the property geology and sample locations are given on Map 87-76-

01 (in back pocket).

The ferruginous metasediments of the Savant Lake property form the

intermediate portion of a regional stratigraphic sequence which grades from basal

conglomeritic sediments in the east, to arenaceous metasediments in the west

(Bond, 1977). In the field the ferruginous metasediments were subdivided as

greywacke, siltstone and oxide facies banded iron formation. All three

ferruginous metasedimentary units are distinct and occur interbedded with abrupt

to sharp contacts between them as illustrated on plates l and 2. Within the

property boundaries gradational contacts are rare.

The ferruginous greywacke is the dominant rock type within the mapped

area and occurs evenly distributed comprising 6096-7096 of the total outcrop

exposure. The individual units range in thickness from l cm up to 5 m and appear

massive in outcrop. The coarse grain size and general lack of graded bedding

visible within this rock type suggests a turbidite type depositional environment

which allowed for quick accumulation of thick sequences of sediment lacking

pronounced internal structure.

l. ..

l l l l l l l

l l l l l l l l l

The ferruginous siltstone which comprises 2096-2596 of the total outcrop

exposure, is evenly distributed throughout the property and occurs as beds and

bands ranging in thickness from l cm to 2 m. Unlike the ferruginous greywacke

this unit frequently displays internal graded bedding with individual graded beds

ranging in thickness from 2 mm to 3 cm. The finer grained nature and graded

bedding within the individual bands suggests that these units were deposited either

during periods of quiesence, or as a more distal facies to the coarser ferruginous

greywacke.

The oxide facies banded iron formation is the least abundant of the three

ferruginous metasedimentary units comprising only 596-1096 of the total outcrop

exposure and is composed of alternating 1-2 mm wide laminations of fine-grained

magnetite crystals and chert. It occurs as interbedded bands up to 60 cm wide

within both the ferruginous greywacke and siltstone, not as a separate thick

mappable sequence. The bands of iron formation are, however, most abundant in

a zone flanking the iron formation poor core of the large northeasterly trending

syncline as illustrated in Figure 5 and Map 87-76-01 {in back pocket). This iron

formation rich zone forms the base of the ferruginous portion of the regional

metasedimentary sequence mentioned earlier.

Although the iron formation within both the greywacke and the siltstone

is compositionally the same, structurally it differs. Bands of iron formation that

cap the finer grained siltstone are generally less disturbed and more continuous

along strike than those found interbedded within thick sequences of greywacke.

Within the greywacke, the iron formation often appears contorted, discontinuous

and in general "ripped" apart. These features are the result of pre-consolidation

deformation as the contorted bedding which could be mistaken for parasitic

folding, is not reflected in the sedimentary units immediately above or below the

distorted bands. The differing structural nature of the iron formation within the

respective metasedimentary units is reflective of their contrasting despositional

environments mentioned earlier.

Arenaceous metasediments are the least abundant of the

metasedimentary units found on the property and comprise only 296-396 of the

DERRY. MICHENER. BOOTH Se WAHL

total outcrop exposure. A thick wedge of these sediments does occur along the

eastern shore of the mapped grid area between L3+OOW and 6+OOW (Map 87-76-

01), but in general these units are less than 3 m wide and occur interbedded within

the ferruginous metasediments mainly in the southern portion of the grid area.

Locally, thin beds of intermediate feldspar lapilli tuff are found

intercalated within the sedimentary sequence. These tuffaceous bands are

generally less than 3 cm wide and occur within the coarser ferruginous greywacke

units, although a separate thick band does occur between LIO+OOE and Lll+OOE at

approximately 1+25 N (Map 87-76-01, in back pocket). These intercalated

tuffaceous units are believed to be related to the felsic to intermediate volcanics

which exist to the northwest, off the claim group, as mapped by Bond (1977).

Rare late Precambrian ultramafic dykes and sills are known to intrude the

complete sequence in the Savant Lake area and a particularly thick gabbro dyke

was noted around L5+OOE, 2+50N as illustrated on Map 87-76-01 (in back pocket).

Here the dyke is approximately 15 m wide and trends roughly southwest,

subconcordant to bedding.

Structural Geology

Structurally, the property is controlled by a tight northeasterly trending

syncline located near the centre of the mapped grid area, as illustrated in

Figure 4 and Map 87-76-01 (in back pocket). Shearing and faulting are developed

locally and are related to the large northeast trending Savant Lake fault and tight

synclinal fold.

Bedding and plunge orientations taken from the various metasedimentary

units on the property indicate that the axial plane of the northeast trending fold is

slightly overturned, dipping 80O southeast, and plunges steeply to the southwest.

The arcuate nature of the axial trace and the shape of the folded iron formation

rich band, suggests that a second weaker phase of folding of unknown orientation

has been imprinted on the dominating structure.

DERRY. MICHENER. BOOTH a WAHL


-10-

A northeast trending shear zone, at least 25 m wide, occurs underwater

between the two very small islands just west of Girard Island in Savant Lake

(Figure 4). Here, the metasediments are highly sheared to schistose; show

increased alteration; are intruded locally by discontinuous quartz and carbonate

veins; and host significant sulphide mineralization (Figure 6, Plate 3). Similar

shearing of decreased intensity also occurs along the western shore of Savant

Lake, between lines 4+OOW and 5+OOW, but no associated quartz/carbonate veining

or mineralization was noted.

Faulting, with minor displacement, occurs throughout the property related

to the large scale faulting and folding in the area. Small scale reverse faults that

parallel the Savant Lake fault occur locally with displacements up to 5 m and are

illustrated on Map 87-76-01 (in back pocket). Fracture cleavage at a high angle to

bedding occurs throughout the metasedimentary sequence on the property and is

believed to be related to the stress induced on the rocks during folding. All the

small scale breaks are clean and sharp with no associated shearing or alteration.

Gold Mineralization

Within the Savant Lake area, gold mineralization occurs within rocks

similar to those found on the property. Two showings in the immediate vicinity of

the property are the One Pine Lake showing and the Shoal occurrence (Figure 5).

At both of these locations gold is found in association with sulphide mineralization

in altered sequences of banded iron formation within northeasterly trending shear

zones. Assays to 0.76 oz. Au/ton over 0.46 m have been reported at the One Pine

showing and grab samples to 0.505 oz. Au/ton at the Shoal occurrence. A detailed

account of these and other showings in the area are given in Trinder and Taylor

(1987).

Similar alteration and sulphide mineralization in a wide northeasterly

trending shear zone occurs within the Savant Lake property, just west of Girard

Island (Figure 4). Here, pyrite, arsenopyrite and chalcopyrite are found in

association with sulphidized banded iron formation and discontinuous quartz and

carbonate veins {Figure 6, Plate 3). Although the samples taken from these islands did not return significant gold values, the shear zone can be traced for approximately 500 m along strike, and holds the potential to host significant gold mineralization.

Sporadic pyrite occurs throughout the remainder of the cut line grid area as small euhedral crystals. This mineralization does not occur associated with any structure or increased alteration and no anomalous gold values were obtained (Appendix li).

PROPERTY GEOPHYSICS

Magnetic Survey

The geophysical surveys were originally scheduled to be completed in the winter months during freeze-up as about 3096 of the property is water covered. Iron formation and shear/fault structures are considered to be the prime host environment for gold mineralization on the property. Therefore, it was decided to complete the land portions of the geophysics during the summer mapping program in order to provide on-site geophysical information that might direct the mapper to specific areas containing iron formation concentrations and/or major structures.

The property has abundant outcrop and is almost totally underlain by ferruginous sediments, (see Geology section elsewhere in this report). As a result, the property's magnetic background is 4,000 to 5,000 nT above the expected earth's total magnetic field in the area. Although there are specific zones having very high magnetite content, the magnetite generally occurs as multiple narrow lenses throughout the grid. The area has a very thin veneer of overburden resulting in the magnetometer's sensor being very close to the magnetic sources in most places. This environment produces magnetic gradients throughout the grid that are greater than the Geonics G-816 proton magnetometer's rated tolerance of 300 nT per foot. The operator found that repeated readings at each station

were very erratic and the survey results were considered unreliable. Logistics, cost and time factors precluded the use of a fluxgate magnetometer on the property during the present investigations. This type of instrument is not affected by steep magnetic gradients.

VLF Electromagnetic Survey

The VLF electromagnetic survey utilized a Geonics EM-16 instrument to measure the secondary field components of the primary field produced by the VLF transmitter station at Cutler, Maine (24fl KHz.). Measurements of the in phase and quadrature values were taken every 25 m along the survey lines. A total of 28.7 line kilometres of data were collected in this way.

The results were plotted in the field in profile form at a scale of 1:5,000. Subsequently, office compilation consisted of entry of the data values on the field maps into a computer system for machine plotting. The conductors detected by the survey are indicated by postive to negative profile slopes proceeding in the north direction as shown on Map 86-76-02.

Results

Numerous anomalous conductive responses were detected by the survey. These tended to be localized with poor line to line continuity. Peak to peak amplitudes varied from weak responses of about 1096 to 2096 to zones exceeding 6096. Trend directions varied between east-northeast to north-northeast. The conductive responses formed discrete groupings or clusters. All of the higher amplitude anomalies were located in swampy or low topographic areas generally following the drainage direction.

The anomaly patterns suggest that some cross-cutting fault or fold structures may be present on the grid. Interpretation of such structures, at this time, is not warranted unless additional confirmation is obtained by either

geological evidence and/or additional geophysical results such as magnetics. The correlation of the higher amplitude VLF conductors with swampy areas may reflect either conductive overburden effects or underlying weakly conductive shear/fault structures. One such conductor, located on the base line between lines 0+00 and 4+OOW, correlates with a fault zone interpreted from the geological results. Other lower amplitude conductors may be related to contacts, foliation direction, shears or conductive overburden. It should be noted, however, that the general trend of most of the VLF conductors is parallel or subparallel to the regional fold axis of the area suggesting that many of the responses may in fact have a structural source. A more comprehensive picture of the structures on the property will be obtained when the water portions are completed and adequate magnetic results are available.

CONCLUSIONS

The Savant Lake property is underlain by ferruginous metasediments with lenses of arenaceous metasediments and intermediate feldspar lapilli tuff that are folded into a northeasterly trending syncline. Faulting and shearing occur locally and are associated with the regional folding and the Savant Lake fault.

Sulphide mineralization was found on a small island immediately west of Girard Island, in Savant Lake, in a wide northeasterly trending shear zone. Although no significant gold values were obtained from sampling of this zone , the sulphide mineralization and structural setting is similar to iron formation hosted gold occurrences in the area. Therefore, significant gold mineralization may occur in rocks under water along strike in this structure.

The VLF electromagnetic survey located several northeasterly trending conductors of limited extent on the property that correlate with low lying swampy areas. These swamps may be underlain by weakly conductive shear/fault structures, but geological mapping did not find supporting evidence.

PROPOSED EXPLORATION PROGRAM AND BUDGET

The Phase I exploration program of the Savant Lake property focused on the mainland portion of the claim group with only reconnaissance prospecting of the remaing water covered claims. This prospecting located significant sulphide mineralization in a wide shear zone just west of Girard Island. Although significant gold values were not returned from this zone, the structure is not yet fully outlined and warrants further examination along strike. In addition, other structures may exist on Girard Island or other islands near the Savant Lake fault.

A Phase II exploration program is proposed for the fall of 1987 that would focus on the islands within the claim group to search for and locate other potentially mineralized shear zones. This program would include: chaining a grid; geological mapping; geochemical sampling; a VLF electromagnetic survey; and a fluxgate magnetometer survey. Also included in this program would be a fluxgate magnetometer survey of the mainland cut line grid as the instrument used in the Phase I program could not handle the steep magnetic gradient encountered.

Contingent upon favourable results in Phase H, a third winter phase is proposed which would include diamond drilling of any prospective targets. At that time the remainder of the property that is water covered would be covered by VLF electromagnetic and fluxgate magnetometer surveys.

VLF Electromagnetic Unit

Pioneered and patented exclusively by Geonics Limited, the VLF method of electromagnetic surveying has been proven to be a major advance in exploration geophysical instrumentation,

Since the beginning of 1965 a large number of mining companies have found the EM16 system to meet the need for a simple, light and effective exploration tool for mining geophysics.

The VLF method uses the military and time standard VLF transmissions as primary field. Only a receiver is then used to measure the secondary fields radiating from the local con ductive targets. This allows a very light, one-man instrument to do the job. Because of the almost uniform primary field, good response from deeper targets is obtained.

The EM16 system provides the in-phase and quadrature components of the secondary field with the polarities indicated.

Interpretation technique has been highly developed particularly to differentiate deeper targets from the many surface indications.

Principle of OperationThe VLF transmitters have vertical antennas. The magnetic signal component is then horizontal and concentric around the transmitter location.

Specifications Fie

i/LF transmitting stations.

Any desired station frequency can be supplied with the instrument in the form of plug-in tuning units. Two tuning units can be plugged In at one time. A switch selects either station.

About 15-25 kHz.

(1) The vertical In-phase component (tangent of the tilt angle of the polarization ellipsoid).(2) The vertical out-of-phase (quadra ture) component (the short axis of the polarization ellipsoid compared to the long axis).

In-phase from a mechanical inclino meter and quadrature from a calibrated dial. Nulling by audio tone.

Reading time 10-40 seconds depending on signal strength.

Operating temperature range 40 to 50* C.
