SUMMARY
Homestake Mineral Development Company is the holder of 32 unpatented mineral claims covering approximately 518 hectares in the Red Paint Lake area, Thunder Bay Mining Division, Ontario.
The claim group covers a portion of the Upsala-Firesteel River metasedimentary-metavolcanic belt, consisting primarily of subaqueous tholeiitic mafic metavolcanics locally interlayered with a thin unit of felsic tnetavolcanic and metasedimentary rocks. Past work records and recent reconnaissance evaluation by Homestake suggested potential for massive sulphides within the felsic sequence where chloritoid bearing altered zones are manifested.
A limited Max nun 1 horizontal loop EM survey has defined a quality conductor correlative with the area of observed alteration and coincident with a swampy linear depression. The conductor appears to be a steeply dipping near-surface thin sheet, possibly due to sulphide mineralization or graphitic schists. The conductive horizon remains open along strike.
Followup drilling is required to test the best portions of the conductor.

1. INTRODUCTION
1.1 Scope
This report summarizes the results o i a M ax Min i horizontal loop EM survey conducted over a portion of the Red Paint Lake Property, Norway Lake area, Thunder Bay Mining Division, Ontario.
This survey was conducted to evaluate the potential for base metal/gold mineralization associated with a particular sequence of Archaean age metavolcanic and metasedimentary rocks. A separate Homestake Mineral Development Company report (Christie, 6.J. and Flanagan, J.M., 1987) describes the preliminary geological reconnaissance and 1ithogeochenical work which provided the basis for recommending the survey method and target area. The reader is referred to that report for background information regarding the regional and property geology in the Red Paint Lake area.
1.2 Location and Access
The Red paint Lake Property is located immediately east of Red Paint Lake, approximately 37 km. NE of Atikokan and 215 km. NW of Thunder Bay (Figure 1).
The centre of the property is situated at latitude 49 2' 45" N and longitude 91 23' W on 1:50,000 N.T.S sheet 52G/03. The magnetic declination is approximately 1 E.
Access to the property is obtained through a network of logging roads situated about 45 km. north of the sawmill town of Sapawe. Sapawe is accessible via Highway 623, 24 km. east of Atikokan.
1.3 Property Ownership
The Red Paint Lake Property consists of 32 unpatented mineral claims covering approximately 518 hectares (Figure 2). Claim status details are summarized in Table 1. All the claims are wholly owned by Homestake Mineral Development Company.

Figure 2. Detailed claim map of the Red Paint Lake Property. HLEM Survey ar»a
The horizontal loop EM survey was carried out by personnel oi Northwest Geophysics Limited under contract to Homestake Mineral Development Company. The survey Mas limited to a restricted portion o i t he property in the vicinity of stratabound sulphide mineralization at a metasediment/metavolcanic contact. The survey totalled 5.0 line km. over 1.4 km. of baseline and IS crosslines spaced at 100m intervals. The work was completed by two geophysical technicians over a two day period: October 14-15 incl., 1987.
1.5 Physiography
Topographic relief on the property is moderate with abundant outcrop. In the survey area local relief is 10-15 meters with a central swampy gully dominating the axis of the survey grid. A low hill parallels this linear trough on the north side of the grid within the volcanic assemblage.
Overburden consists of a thin cover of sand and boulders. Ice movement appears to have been towards the SW.
1.6 Previous Work
The Red Paint Lake area has experienced sporadic exploration activity since the 1890's when gold was first discovered in the area. A small mine - the Golden Winner - was established and in 1900 15 tons of ore were milled grading 0.29 oz gold/ton on average. Subsequent minor flurries of staking and exploration activity, concentrating on gold, took place during the 1937-1939 and 1946 to 1952 periods. After a lull the area experienced renewed exploration when Barringer Research commenced a series of geological, geophysical and soil geochemistry surveys which redefined and extended the known Alcock copper Showing. No followup drilling was attempted and the claims were allowed to drop.
In the late 1970's Nining North Explorations Limited commenced a comprehensive regional evaluation within the Red Paint Lake greenstone belt. A total of 163 claims were staked and limited trenching carried out on several base metal targets. Later geological napping, soil sampling and a series of geophysical surveys were conducted. Previously known anomalous zones were further enhanced and a new copper anomaly discovered within carbonate altered volcanic 0.8 km. SW of the Alcock showing.
In 1983 the area was re-mapped by the O.6.S. and Billiton

optioned the Mining North property. They conducted soil and till geochemical surveys over a volcaniclastic/metasediment unit within the ma-fic volcanic deemed favourable for base and precious metal mineralization. In 1984 three target areas were trenched, sampled and mapped in detail. Low bedrock geochemical values Mere obtained and the claims were allowed to lapse.
Homestake staked 32 claims in 1987 to cover the Alcock Showing and other zones of intense iron carbonate alteration. Reconnaissance mapping and lithogeochemical sampling were carried out over most of the claims aided by a wide-spaced (200m.) grid totalling 14.8 line km. Although no areas of significant bedrock gold values were detected, a prospective volcanogenic massive sulphide target area was outlined by locally intense chloritoid alteration within sericite schists along the north contact of a metasedimentary/metavolcanic horizon. An HLEM survey, subject of this report, was commissioned to aid in defining potential massive sulphide targets for follow-up.
2. GEOPHYSICS
2.1 Instrumentation
The instrument used for this survey was a Max win 1 owned and operated under contract by Northwest Geophysics Ltd. The Maxmin 1 is a horizontal loop electromagnetic system <HLEM). The transmitter and receiver are interconnected by a reference cable permitting the measurement of the EM field (primary and secondary) at the receiver as a percentage of the theoretical primary field at the receiver. The components measured are the in-phase and out-of-phase as a percentage of the primary field. Measurements at more than one frequency provide a check on the accuracy of the method and permit detection of overburden conductivity effects. In this case 444 Hz and 1777 Hz were employed for the low and high frequencies respectively.
2.2 Survey Method
The survey was limited to a 1.4 km. long E-W grid over the anomalous and altered horizon. Grid lines were re-cut and re established from the previous Billiton soil survey grid with 100 meter spaced lines and 25m picketed stations. The survey limits extended from lines 900W to 500E and from station SOS to 500S maximum for a total survey of 5.0 line-km.
The entire grid area was covered at 100m coil spacing and 25m station readings for both the low and high frequencies. Over anomalies the station separation was reduced to 12.5m on most lines. Further detailed surveying was carried out over selected anomalies on 5 lines using 50m coil spacing and 12.5m station

| readings for both frequencies. The survey was completed in two days using a two ffian field crew. The survey results were

2.3 Results
Maps 1 and 2 display the profiled survey results for the 100m coil separation data at each frequency. The conductor was detected over the entire length of the grid although it weakens slightly on the extreme east lines. In general the results depict a narrow, strongly conductive near-surface zone extending from 900W/150S to 500E/212.5S. The conductor is roughly coincident with the swampy gully and is nowhere fully exposed. Examination of the profiles suggests a near vertical to occasionally steeply north dipping conductor. The strength of the response varies along strike but is consistent with a narrow sheet-like conductive source. The strongest conductivity was obtained over lines 00 to 100W and also on line 900W. Survey results correlate well at both frequencies with the 1777 Hz data exhibiting the best anomaly definition.
Maps 3 and 4 show the 50m coil separation detail profiles over the conductor on 5 of the lines. The results of the detail survey provide essentially the same information as the base 100m separation survey,
3. CONCLUSIONS AND RECOHHENDATIONS
The Maxmin 1 HLEH survey was successful in delineating a moderate to strongly conductive horizon at or near the north contact of a metasediment/netavolcanic sequence. The zone correlates with a swampy depression south of napped sericite- chloritoid schist alteration. Siliceous (rhyolitic?) brecciated rocks and layered chert hosting disseninations and clasts of pyrite occur to the south of the conductive zone. Minor graphitic seams and partings occur within the cherty units. The conductor in the surveyed area is not exposed due to swamp and overburden.
Follow-up work in the form of one or two short drillholes would be required to test the nature of the conductor. If the conductor consists of massive sulphides the geochemical data collected to date suggests low to negligible base metal content. Alternatively the conductor may represent a formational conductor associated with graphitic sediments.
