The assessment work was conducted on a group of claims located on the Gang Ranch. The area lies west of the Fraser River on the Interior Plateau of British Columbia. The claims were located on Crwon Lands held under lease by the Gang Ranch. The owners of the claims, BSA Investors Ltd., are the same corporate entity as the owners of the Gang Ranch. The area is accessible from either Clinton,B.C. or Williams Lake,B.C. by public roads. These roads are not paved all of the way but the gravel portions are well maintained. The claim group is accessible from the Gang Ranch headquarters by driving north from the ranch on 2700 Road. The original group of 22 claims lies in the area bounded on the north by Word Creek, on the east by the Fraser River, and on the south by Churn Creek. The 8 claims for which this assessment work was done are bounded roughly by Word Creek on the north, the Fraser River on the east, and Prentice Gulch on the south. No new access roads were constructed to accomplish this assessment work. The entire group of claims is shown on the claim map which is a part of this report, and which is based on the Dog Creek Sheet No. 92-0/9.

These claims were staked on behalf of BSA Investors in 1989 as a result of prior airborne magnetometer and VLF surveys. There is no known history of exploration or mining in this claim area. There is some evidence of old placer efforts along the bank of the Fraser River and in Churn Creek to the south, but these sites do not show any extensive work.

This project is at an early stage of exploration and no data is available with which to make an economic evaluation of the property.

The entire group of claims, as originally staked, consisted of 22 claims named RCRL Nos. 1 through 22, for a total of 398 Claim Units. The group of claims for which this assessment work is filed are RCRL No. 1 through No.6, RCRL No.21, and RCRL No.22, for a total of 156 Claim Units. W INDEX MAP GANG RANCH, B.C. Page 2 Page 3

SUMMARY OF WORK

Geochemical Geochemical soil sampling was conducted on the claims in June 1989 as part of a second phase of exploration. A total of 430 soil samples and 53 rock chip samples were collected. All samples were assayed for gold, silver, copper, arsenic, and antimony. This amounted to 2,415 chemical determinations. Several anomolous areas were defined which were coincident with anomolies from prior aerial surveys.

Geophysical k Induced polarization (IP) surveys were conducted along 4 miles of tk .r 4Kh) line with 50 meter dipole spacing. The locations of these IP lines are shown on the claim map which is a part of this report. The details of the IP work are discussed in the Barringer Geoservices report in Addendum "B".

Geologic A geologic survey was conducted over the entire area of the 22 claim group. This was done on a reconnaissance basis to better define the geology of the claim area and to refine the published information that was regional in content. Glacial debris and basalt flows obscure the geology of the area in large part. Page 4

AUGUST, 1989 EXECUTIVE SUMMARY

Detailed soil sampling was completed over eight areas on the deeded land of the Gang Ranch in June 1989 as part of the second phase of an integrated precious metal exploration program. Seven of the eight areas were defined by anomalous stream sediment geochemistry and airborne geophysical anomalies in

September, 1988; the eighth area was identified by an anomalous

silver value in a rock chip sample. A total of 430 soil samples

and 53 rock chip samples were collected; all samples were analyzed for gold, silver, copper, arsenic and antimony.

Soil samples in -Anomaly 6 (Word Creek) defined two areas of anomalous gold values associated with felsic intrusive rocks in an intermediate to mafic intrusive complex of Jurassic age. Each of these areas is coincident with the margins of aeromagnetic highs and may reflect mineralization associated with alteration zones adjacent to the intrusive complexes.

Maximum gold values in the soil were 110 ppb Au; a stream sediment sample in the center of the western anomaly in Anomaly

6 contained 427 ppb Au. A sample of hornblendite in the eastern

anomaly yielded 165 ppb Au in outcrop.

The remaining areas produced several samples containing high gold values that were not supported by elevated copper, arsenic, or antimony values and are thought to be due to detrital specks U of gold in glacial till overburden. High arsenic values in Page 11

w Anomaly 5 rock chip samples may warrant additional investigation but this area is assigned a low priority.

A total of four miles of Induced Polarization (Ip) data were

acquired on three lines at the Gang Ranch between the 14th and 22nd of July, 1989. Induced Polarization is the most commonly-used ground geophysical exploration tool for metal deposits and their associated zones of alteration.

A two mile long IP line was acquired from south to north

crossing Gaspard Creek to test Anomaly 1. Large thicknesses of sandy overburden are visible throughout the drainage systems and.

road cuts at the southern end of the line, and rock outcrop is not visible anywhere along the line. The IP data shows no significant resistivity variations along the line, and the

chargeability psuedo-section is very flat. Geochemical soil and stream samples were acquired at 50 meter intervals along the line in an attempt to locate the potential source of anomalous samples taken from the Gaspard Creek drainage system, but only erratic gold values were detected.

”- .Anomaly_____- _--. 6 /--’was tested by two IP lines, the first a one mile /’ long linelrocated on the eastern anomaly south of Word Creek and west of Fraser River. The topography along the line drops more

present. Two IP anomalies were detected at the northeast end of ’CI the line. A relatively shallow chargeable zone is present at Page 12

approximately 775-950 meters, and a deeper zone is present at W approximately 1200-1500 meters from the western end of the line. Both IP anomalies show a good correlation with the aeromagnetic data, located at the high gradient portion of

magnetic highs. The VLF (airborne electromagnetic) curve also shows some correlation, but is less significant than the

magnetic data. Geochemical samples were taken at 50 meter intervals along the line, in addition to samples taken from outcrop both to' the northwest and southeast of the IP anomalies.

on the western anomaly, two miles to the northwest. The line crosses Word Creek and was chosen to follow-up anomalous W geochemical results over a favorable magnetic signature. The

line crosses several large drainage systems, but rock outcrop

was only noted on the southwest portion of the line. A major IP anomaly was detected 200-450 meters from the west end of the line. The anomaly appears to be relatively shallow, and is characterized by chargeabilities of the same magnitude as those

measured for the anomalies noted above. Geochemical samples were taken at 50 meter intervals along the line, plus two additional lines of soil samples to confirm the previous geochemical results.

Analysis of the soil and rock samples collected along the IP

lines on Anomaly 6 showed that the IP anomalies are coincident rllrr with geochemical anomalies in gold, silver, copper and arsenic. -iii- CONCLUSIONS

Phase I1 exploration of the Gang Ranch areas has focussed

attention on the northern part of the area, designated Anomaly\ 6 in the Phase I exploration. This anomalous area was interpreted from the airborne geophysics as an alteration aureole around a highly magnetic and weakly conductive body associated with intrusive rocks. The airborne data were supported by signs of alteration in exposed rock and geochemical rock samples containing gold, arsenic, copper and antimony. Further geochemical sampling and geological mapping has confirmed and extended Anomaly 6 with the discovery of additional anomalous gold, copper, arsenic and silver values in soils and rocks. This data 'Ilr was used to direct the placement of two IP lines which were successful in detecting three strongly anomalous, polarized zones at depth which could indicate the presence of sulfides or clay-type alteration often associated with gold and base metal mineralization. Soil and rock samples collected along the IP lines confirmed the presence of anomalous gold, silver, copper and arsenic values coincident with the IP anomalies.

Additional Phase I1 work on the other Gang Ranch anomalies confirmed the presence of erratic gold values, but did not define specific targets for immediate follow-up.

-iv- RECOMMENDATIONS __c___L_----

Based on the discovery of the three anomalous induced polarization zones with associated gold, silver, copper and arsenic anomalies near the northern limit of the staked ground

on Anomaly 6, the following course of action is recommended:

n Y 1. Stake at least deblock of claims to the north of the present to provide protection to

the north. 4

2. Establish the strike direction and continuity of the IP anomalies through a program of parallel IP lines. W 3 Trench the existing anomalies in areas of shallow overburden to determine the geological and geochemical character of the sub outcrop.

4. -- Drill a total of not less than 500 meters to test the three conductive zones, using at least two diamond drill holes per anomaly.

This program should cost between $100,000 and $125,000 depending on the cost of building drill roads to the selected locations. 'err

-viii- I (. INTRODUCTION

This report describes the results of the second phase of an integrated mineral evaluation program on the deeded land of Gang

Ranch. The first phase, completed in September, 1988, consisted of reconnaissance stream sediment and soil sampling surveys and geological mapping followed by an airborne geophysical magnetic and VLF electromagnetic survey. Six anomalous areas were defined by

these surveys and were followed up in June, 1989 by detailed geological mapping and soil sampling in order to further evaluate these areas and to define discrete exploration targets.

One of the original six anomalous areas, Area 2, was split into

three smaller areas designated Areas 2, 7 and 8, for the purpose of

the Phase I1 exploration. Area 10 was also added based on an anomalous silver value analyzed in a rock chip sample collected by David E. Aro, consultant. No additional samples were collected in

Area 1 because of problems of glacial overburden thickness.

In July, 1989, four miles of reconnaissance induced polarization

(IP) was surveyed over Areas 1 and 6 to test for subsurface sulfide mineralization, and further geochemical samples were collected and analyzed to complete Phase Two exploration operations.

This report integrates the geochemical results with the IP data

from Areas 1 and 6 and outlines the recommended next phase of the " exploration program. -I- Page 19

11. GENERAL GEOLOGY

The regional geology of the area is described by Mathews and Rouse (1984), Beview (1983), and Monger (1977). A detailed description of the geology is given by Barringer Geoservices,

(1989). The following is a brief description of the rock types in the Gang Ranch project area, but more detailed geologic descriptions are included in the discussions on individual areas.

The rocks of the area belong to two Broad age groups:

a late Mississippian to middle Jurassic marine volcano- sedimentary sequence of chert, limestone and greenstone,

intruded by a diorite-gabbro- ultramafic complex of late(?) Jurassic age with scattered felsic intrusive bodies of quartz monzonite and; a Tertiary bimodal sequence of volcanic flows, ash-flow tuffs, and flow breccias ranging in composition from basaltic to rhyolitic.

Underlying the youngest basalts (Pliocene) are fluvial and

lacustrine sediments that are most prominent to the north of Area 1

(Figure 1). A thick cover of transported overburden remains in most of the topographic lows of the major stream drainages, especially near the Fraser River where a thick section of glacial till occurs at the top of the slope and fluvial material forms prominent 'pr terraces within the Fraser River valley.

-3- 111. GEOCHEMICAL METHODS V

Soil samples were collected along grid lines at 200m or 100m

intervals in all but two of the areas. The exceptions were Areas 5

and 7 where the availability of outcrop and severe topography respectively, required an alternative to soil sampling along a

regular grid. All soil samples represent the top layer of soil; a garden trowel was used to scrape the surface in several spots within a 5m radius of the sample location in order to collect approximately 5004 of soil. Gravel sized and larger rocks in the soil were not

included in the sample. The laboratory analysis of the soil samples

included only the -80-^I .mesh fraction. All samples were analyzed for gold (Au), silver (Ag), copper (Cu), arsenic (As), and antimony (Sb)

at Barringer Laboratories Inc., Toronto. Several stream sediment samples were also collected within the anomalous areas and again a

-80 mesh fraction was separated for analyses of the above elements. Results of all analyses are given in Appendix A.

Rock chip samples were collected where alteration was apparent

in outcrop within the anomalous geochemical areas. Most rock chip samples are from Areas 5 and 6 where outcrop is abundant. The rock chip samples were pulverized to -_--200 mesh and analyzed for gold, silver, copper, arsenic, and antimony. Descriptions of these samples are given in Appendix B.

-4- Page 21

rv. GEOCHEMICAL RESULTS

Plates 1 - 26 give the locations of the samples collected and their analytical values of gold, copper, arsenic and antimony. Since values of silver were generally less than the detection limit

(0.2 ppm) in all areas, the few samples with >0.2 ppm Ag are shown together with the gold values for each area. Similarly, only Areas

3 and 6 have maps showing antimony results since the other areas do not possess det'ectable antimony.

Area 1

No additional work was undertaken during this part of Phase I1

W because of overburden thickness. An induced polarization survey was carried out in this area to locate potential bedrock targets as described in the Reconnaissance Induced Polarization Survey section following.

Area 2

Most of Area 2 is covered by basaltic boulders and associated volcanogenic sediments. Transported overburden material covers the eastern half of the grid area although small exposures of Triassic greenstone and chert were found in some of the more deeply incised drainages in the southeastern portion of the sample grid. Soil sample lines in this southeastern portion were generally on ridges w in relatively thin glacial cover.

-5- Page 22

Soil samples were collected on a 300m x lOOm grid along five W east-west lines paralleling the principal drainage in the area. The sampling grid was centered on the area of anomalous stream sediment

samples collected during Phase I of this project. Plates 1 - 4 show the sample locations and geochemical values for the soil samples in

Area 2.

With the broader data base from these soil samples, the elevated values of coppe;, arsenic and antimony detected by the Phase I stream sediment sampling program remain above background and hence are anomalous although on present information not significant indicators of local mineralization. Most of the high gold values

occur in samples that have low levels of silver, copper, arsenic and w antimony suggesting that the gold in these samples may be due to the odd speck of free gold among the glacial till material. Sample 254 contains 257 ppb Au, but the other elements are either below

detection limits or at background levels. Samples 242, 259, 260 and

261 form a small cluster of elevated copper and arsenic values in the north-central part of the sample grid which appears to reflect the geochemical signature of underlying greenstone and diorite.

-6- Page 23

Area 3 W

The predominant rock types in Area 3 are basalt and andesitic tuff occurring as flows and flow breccias. The terrain in this area consists of thickly wooded, gentle slopes with few outcrops except on the ridge along the southernmost sample line. Glacial overburden appears to be thin in this area.

The soil sample grid consists of four east-west lines spaced

500m apart centered on either side of an easterly flowing drainage.

Sample spacing was lOOm along the inner two lines and 200m along the outer two lines. The objective of the soil sampling in this area was to detect the source and possibly the trend of mineralization w that gave rise to the anomalous stream sediment samples collected during Phase I. Plates 5 - 9 show the sample locations and

geochemical values for the soil samples in Area 3.

The geochemical results do not show a concentration of anomalous soil samples or indicate any trend of mineralization through this area. A high gold value (153 ppb) in the line north of the stream drainage may not be significant since silver, copper, arsenic, and antimony are at background levels. Arsenic and copper are slightly elevated in the eastern end of the grid and may again reflect underlying geology.

-7- Page 24

The lack of significant geochemical anomalies or signs of a w geochemical trend greatly reduces the potential of Area 3, and on present information, this area is considered a low priority for further investigation.

Area 4

No outcrops occur within this area. A thick sequence of glacial till represented by coarse conglomerate, sand and clay underlies the area forming steep cliffs above Churn Creek to the south. The eastern ends of the sample lines fall on a nearly flat terrace immediately above the Fraser River.

The soil samples were collected at lOOm intervals along three W 200m spaced east-west lines. Severe topography somewhat altered the

parallel design of the sample lines. Plates 10 - 13 show the sample

locations and geochemical values of the soil samples in Area 4.

The geochemical results confirm that the high values of copper and arsenic are uniform over this area. They are not thought to represent dispersion of metals from buried localized mineralization, but rather to reflect the till overburden geochemistry. In

this section gold values are 3 ppb or less and antimony values are

all less than the detection limit of 0.2 ppm.

No further work is recommended in this area.

')r -a- Page 25

Area 5 wiv

The stream banks surrounding'the stream sediment anomaly collected during Phase I consist of discontinuous outcrops of an oxidized basaltic flow breccia that is locally silicified and contains small, single quartz-pyrite veinlets along fracture planes. Several outcrops of this flow breccia form steep walls and cliffs over the stream. Between outcrops and away from the stream bed a thick seqbence of lacustrine sediments overlie glacial till that is severely slumped on the south side of the stream.

Twenty-three rock chip samples were collected in this area in order to take advantage of the prominent outcrops. Two soil sample psl lines' spaced lOOm apart were put in on either side of the stream. Ten samples were collected on each line- Plates 14 - 17 show the sample locations and geochemical values for the soil samples in

Area 5.

The results show one gold anomaly (118 ppb) on the west end of the northern line near a subcrop of silicified basaltic breccia. Rock chips from this subcrop yielded anomalous arsenic values that

were >100.0 ppm. Non-silicified outcrop in the immediate area contained lower, but still anomalous, arsenic values ranging from

8 to 80 ppm. Arsenic values in soil samples are also slightly elevated on the west end of the southern line.

V -9- The one rock chip sample in Area 5 to yield a gold value greater w than the detection limit, GR-505 with 6 ppb Aut was from an outcrop IOm away from the silicified subcrop mentioned above, on the south side of the creek.

Copper values were at background levels through Area 5 except at

the east end of the northern line. A cluster of silver values (all

0.2 ppm Ag) on both soil sample lines occurs in an area of no outcrop in the eastern half of the area, offset from the anomalous arsenic.

A rock chip sample from a small pyrite-quartz veinlet along a fracture in the basaltic breccia yielded only elevated values of w copper and antimony. Gold and silver values were all below their detection limits of 3 ppb and 0.1 ppm respectively.

-Area 6

The Word Creek drainage (Area 6) provides several good exposures of Triassic-Jurassic marine sequence rocks and diorite-gabbro- ultramafic intrusive rocks. Glacial till obscures these outcrops toward the eastern end of the grid approaching the Fraser River valley as well as forming a thin cover on the shoulders of the drainage.

-10- Page 27

The predominant structural orientation of the area is to the w northwest. Outcrops of chert along Word Creek show extensive folding, shearing and attenuation of beds with fold axes trending

N40°W to N50°W. An apparent normal fault bounding a large hornblendite body in the north central part of the grid trends

N3S0W. Felsic dikes in the area appear to be oriented along a similar northwest trend.

Soil samples were collected along three lines spaced A&-.500m apart paralleling the Word Creek drainage, and along three north-south lines spaced 200m apart in the southeastern portion of this area.

The sample interval along both sets of lines was /”--200m-.-* This configuration of sample lines was designed to test the margins of w two prominent magnetic anomalies straddling a gold-copper-antimony stream sediment anomaly detected in Phase I. Several additional stream sediment samples were collected in drainages that had not been tested during the first phase.

Plates 18 - 22 show the sample locations and geochemical values

for the soil samples in Area 6.

The soil sampled near the bottom of the Word Creek drainage

(samples 620 through 629) consists of mechanically weathered fine material locally derived from outcrops rimming the banks of the drainage. On the shoulders of the drainage where the terrain is

)rr -11- Area 6 (cont.) '111

relatively flat the soil consists of a thin cover of glacial material. The clear change of rock types in the soil float from one area to the next, and the presence of scattered outcrops on these more gentle slopes, indicates that these soil samples have tested the fine material derived from local bedrock as well as the thin glacial cover when present.

Rock chip samples were also collected from outcrops that showed signs of alteration.

The geochemical results highlight two__ ..-areas -- of anomalous gold w which are closely related both to margins of magnetic anomalies and to felsic dikes in the diorite-gabbro-ultramafic complex. The gold anomaly in the northwest part of the grid is defined by three soil samples located on both sides of a drainage that yielded a value of

427 ppb Au in stream sediment sample 619.

The felsic dike is not exposed in this part of the grid but an abundance of intrusive, felsic float (quartz monzonite?) lies at the top of the western bank of this drainage. About 250m downstream

from sample 619 a small pyrite-quartz vein within a shear in

silicified chert was found to contain 50 ppb Au, 2000 ppm Cu, and

160 ppm As. Soil samples 620-623 along the center grid line contained low but anomalous amounts of gold with anomalous copper, U -12- Page 29

Area 6 (cont.) W

arsenic and antimony. Sample 621 is centered on an exposure of a small diorite plug and consists primarily of debris derived directly

from the diorite. Sample 622 (58 ppb Au) was collected immediately beneath an oxidized chert outcrop in the south-facing slope directly above Word Creek.

The eastern'gold anomaly is defined by three soil and two rock chip samples spatially associated with the contact of a subcropping felsic dike intruding the chert-greenstone and intermediate intrusive complex. Outcrop is sparse but a rock chip sample from an

oxidized outcrop of hornblendite contained 165 ppb Au, 1.2 ppm Ag,

540 ppm Cu, and 25.0 ppm As. A W nearby rock chip sample in oxidized chert contained 11 ppb Au and 530 ppm Cu. Gold values in the anomalous soil samples ranged from 16 to 168 ppb. The sample with

the lowest gold value contained 230 ppm Cu; copper and arsenic were

near background levels with the higher gold values. A soil sample with 199 ppb Au occurs 1400m to the south of this cluster of gold values along the trend of the felsic intrusive body although no evidence of this dike could be seen in this area. An anomalous

copper value also lies along the trend of the felsic intrusive, 800m south of the cluster of anomalous gold values.

-13- Page 30

Area 6 (cont.) w

Rock chip samples were collected from an area of fractured and

oxidized chert along the northern grid line between samples 608 and 610. Limonitic gossan is present locally in small patches within

shear zones in the chert; calcite veins up to 10 cm wide fill

vertical fractures in the area of samples GR-546 and GR-547. Analysis of the seven rock chip samples in this area show slightly elevated values'of arsenic and silver in several samples but values of copper and gold were less than background levels. Soil samples

taken across a scarp of oxidized chert (samples 607-610) show

elevated values of copper, arsenic and antimony.

The geochemical data outline the location of the felsic dike associated with the eastern gold anomaly. Arsenic values (samples 640-649) in those areas underlain by the diorite are greater than

2.0 ppm whereas soil samples over the felsic intrusive contain less

than 2.0 ppm As, except where associated with anomalous gold values (samples 641 and 667). Other areas of intrusive, felsic float were either too small to be covered by the sampling interval or were

associated with gold anomalies, i.e., samples 603 and 604 in the western anomaly.

Area 7 ct9

Diorite is exposed along a steep slope that parallels the Fraser River valley and transects the sample lines at right angles. The gentle area to the west above this exposure is covered with lacustrine sediments, basaltic boulders and glacial till; below it to the east is a nearly flat terrace of clay-sized material.

Soil samples' were taken along ridges rather than along a strict grid system in order to avoid crossing the vertically walled draws that dissect the terraces along the Fraser River. Samples were collected at lOOm intervals along two principal lines approximately 300m apart. Short lines were added 100m on either side of the main southern line in order to better test the geochemical signature of 'crs the exposed diorite. Plates 1 - 4 show the sample locations and

geochemical values for the soil samples in Area 7.

The diorite is reflected in the geochemical data by slightly higher copper values. Where the sample lines cross the outcrop

copper values range from 32 to 47 ppm compared to average values of

28 ppm for the glacial material above and below (west and east, respectively) this outcrop. The lone gold value above detection

limit (4 ppb) is from a sample in the diorite. Stream sediment samples from small draws immediately south of the sample lines show

a geochemical signature of the diorite with copper values of 35-40

PPm. W -15- Page 32

Area 8 w

Except for the topographic relief of Prentice Gulch (Figure l), this area slopes very gently to the east towards the Fraser River. The northern part of the area is covered by hummocks of basalt boulders, whereas the remainder of the area is covered by scattered basalt boulders and fine glacial material. The latter includes numerous fluvial deposits such as those exposed in the banks of

Prentice Gulch.. Plates 1 - 4 display the sample locations and

geochemical values for the soil samples in Area 8.

Geochemical values from this area are generally at background

levels except for gold and arsenic values up to 9 ppb Au and 9 ppm w As in the southwest and northeast corners of the sample grid. The gold in the southwest corner is associated with elevated arsenic

values of 6-10 ppm. These slightly anomalous areas of the grid do not appear to be related to the original stream sediment anomaly.

As in Areas 2 and 7, the elevated gold values occur in samples that have low levels of silver, copper, arsenic and antimony indicating that the gold in these samples is due to a small fleck of free detrital gold in the glacial till material and is not related to local mineralization.

-16- Area 10 w

This area lies just below a basalt covered plateau in the southern portion of the Gang Ranch deeded property. The basalt overlies a thin andesitic volcanic flow capping a hornblende dacite . .- porphyry. A thin flow of aphyric rhyolite crops out between the andesite and hornblende dacite porphyry. Green chalcedonic alteration in the andesite and the rhyolite flow was sampled during

Phase I and was'found to contain 4 ppm Ag. Since this area did not yield a geochemical anomaly in the local stream sediment samples collected at that time it was not assigned a high priority for

further work. However, this area was included in Phase I1

operations because of the silver anomaly found later. Plates 23 -

26 show the sample locations and geochemical values for the soil W samples in Area 10.

Rock chip and soil samples collected from this location did not reproduce the high silver value from the initial rock chip sample, but a soil sample directly below the altered outcrop did yield a

highly anomalous arsenic value of 26.0 ppm. One soil sample 300m

southeast of the altered outcrop contained 7 ppb Au. The remainder of the samples possessed gold values of less than 3 ppb. Small quartz veins in the hornblende dacite porphyry along the west end of the sample line did not yield any anomalous geochemical values and do not appear to be related to any significant mineralizing process.

Li -17- V. DISCUSSION OF GEOCHEMICAL RESULTS W

The geochemical data show two areas of anomalous gold and copper spatially associated with the margins of positive magnetic anomalies

near felsic intrusive rocks in Area 6 (Word Creek). The Phase I aeromagnetic data suggest an area of alteration in which gold values

greater than 100 ppb in soil and 165 ppb in outcrop define the eastern anomaly. In addition, soil samples with anomalous gold occur along the'western end of the grid surrounding a stream

sediment sample having 427 ppb Au. The coincidence of these geochemical anomalies with the margins of magnetic highs suggests that the source of elevated gold and copper values are zones of alteration manifesting as magnetic lows around felsic to w intermediate composition intrusives.

For the reamining areas, several high gold values in the soil are probably from free detrital gold in the glacial till overburden probably giving rise to stream sediment anomalies through mechanical, heavy mineral concentration by hydraulic action.

Area 5 may warrant further attention where rock chip samples from a silicified basaltic breccia subcrop yielded highly anomalous

arsenic values, greater than 100 ppm As, in the vicinity of a sample

from an outcrop containing detectable gold, 5 ppb Au.

Similarly Area 10 may warrant further attention at a later stage w because of anomalous gold and arsenic values.

vr. RECONNAISSANCE INDUCED POLARIZATION SURVEY

A reconnaissance pole-dipole induced polarization/apparent resistivity (IP) survey was conducted at Gang Ranch, British Columbia for B.S.A. Mining Co. Ltd. The purpose of the three lines t. surveyed was to detect possible sulfide mineralization associated with airborne magnetic anomalies and stream sediment and soil

geochemical anomalies (Barringer Geoservices, 1989). Figure 1 shows the location of' the three IP lines.

Survey Procedures

Qw A pole-dipole array with a dipole spacing of 50 meters was used to acquire induced polarization data for dipole separations of n=l

to 6. The IP effect was measured in the time domain using a

transmitter frequency of .125 hertz (2 seconds on, 2 seconds off, 2

seconds on reversed polarity, 2 seconds off). The IP effect was measured for one full cycle to eliminate electrode polarization

effects. A minimum of ten IP measurements were stacked and averaged for each transmitter-receiver dipole pair, and several dipole pairs were repeated in order to assure good data quality. A three kilometer infinity wire was used to maximize the transmitter input signal.

-20- Page 38

Each day measurements were transferred from the receiver to a WV Compaq personal computer for data processing, with the data being 1 backed up on floppy disk.

The apparent resistivity values for each dipole pair were calculated using the following equation:

Pa = K * V/I (ohm-meters)

where': V = receiver voltage during on part of transmitting cycle (volts)

I = transmitted current (amps)

K = geometric constant for pole-dipole array (meters)

'lrrr Personnel and Equipment

& The geophysical firm of Peter--- E-,+-Walcott-- -_-.-... -_..".-"--_Assoc.- ~ Ltd. ~ were sub-contracted to perform the IP data acquisition. Barringer Geoservices geophysicist, Mark Weber, was present during the survey to perform quality control, and to help maximize the production of the geophysical crew which consisted of:

Peter Walcott geophysicist Alex Walcott geophysical assistant Tom Kocan field assistant Dave Waymouth field assistant

-21- Page 39

The geophysical crew used a 2.5 kW E.D.A. IPTl transmitter and W IP2 receiver during the entire data acquisition.

Discussion of Geophysical Results

The IP data are presented as pseudo-sections on Plates 32, 33 w' and 34. Each plate includes:

1. Second vertical derivative aeromagnetic and first horizontal derivative of the total field airborne VLF profiles.

2. An apparent resistivity pseudo-section. 3 An IP chargeability pseudo section.

4. Geochemical soil values of gold, copper and arsenic.

The second vertical derivative aeromagnetic and total field VLF profiles are from the Phase One airborne geophysical survey while the apparent resistivity, chargeability and geochemical results are c- from the latest Phase I1 program.

-23- Line 1 'Qlr

The location of Line 1 is shown in Figure 1. The line is two miles long and is characterized by low apparent resistivities which

rarely rise above 100 0hm.m and, in several places fall below 10 ohm.m, reflecting a substantial thickness of conductive, glacial overburden. On the central and northern parts of the line the

resistivity results suggest an overburden thickness of at least 90m

using depth of penetration criteria developed by Edwards (1977).

Although the central and northern portion of-r the line indicates relatively consistent horizontal layering of the overburden, the

southern portion indicates a less homogeneous situation with

'cy localized zones of anomalous apparent resistivities

Background chargeabilities generally range between about lmV/V to 3mV/V. There are no priority anomalies on this line. Centered

around station 600 a very weak, poorly resolved anomaly occurs which suggests the possibility of weakly chargeable material beyond the penetrating power of the equipment and electrode spacing used. However, the 'anomaly' is of low priority and does not warrant further consideration, at least until the more important anomalies

on Lines 3 and 4 to be described, have been more thoroughly

evaluated. A one point geochemical gold anomaly coincides with the poor IP anomaly, but eight other gold anomalies along this line show no IP correlation. PY -24- Qw The magnetic and VLF data show no obvious correlation with the IP results.

Line 3 (Line 2 not surveyed by IP)

Two major IP chargeability anomalies occur on the northeastern half of Line 3.

The locatioh of the line is shown in Figure I. The line is one mile long and exhibits substantially higher apparent resistivities than those found on the preceding Line 1. On the central part of

the line resistivities range from about 200 to 500 0hm.m. suggesting bedrock either at, or near, surface whereas at both ends of the line w apparent resistivities drop below 100 0hm.m and indicate the presence of a significant thickness of overburden.

IP chargeabilities increase from a background of less than 2mV/V

in the southwest to 16 to 18mV/V in two separate anomalies along the

northeastern part of the line (Anomalies A & 3). The anomalies exhibit differing characteristics.

Anomaly A peaks at station 950 and appears to represent a chargeable zone dipping to the northeast at a relatively shallow depth. (Because the depth resolution of the n=l IP value is

approximately 20m, the best depth estimate of the depth to the top

-25- 'crpr Page 43

of the chargeable material is 'less than 20m'). Anomaly A possesses W the highest chargeabilities along the whole line and possibly reflects disseminated sulfide mineralization in felsic igneous rocks or silicified sediments. The anomaly correlates with anomalous gold

values at stations 600 and 700 and correlates with an aeromagnetic gradient interpreted to be the contact between a felsic to intermediate intrusive with the surrounding sediments. The airborne VLF profile of the first horizontal derivative of the quadrature component shows'a positive anomaly over both IP Anomalies A and B.

Anomaly B is centered between stations 1225 and 1300 and probably represents a slightly deeper source than Anomaly A. A number of possibilities exist concerning the geometry of the source of the anomaly, the most likely being either a single vertical chargeable zone or two, easterly dipping zones. The IP anomalies correlate with lower resistivities than those of Anomaly A and could be associated with more strongly disseminated sulfide mineralization and/or argillic alteration on the other contact of the intrusive

interpreted from the aeromagnetic data. As with Anomaly A there is a coincident VLF anomaly, but no geochemical anomaly, perhaps because of the increased depth to the top of the IP source.

Both Anomaly A and B are of the highest priority and require trenching and further IP work to discover more about the nature of their sources, and their strike extent and direction, prior to drilling. It should be noted also that Anomaly B is unclosed to the - northeast. Figure 2 shows photographs related to Line 3. -26- Page 44

View along line 3, taken from station 750 showing the Fraser River 1300 feet below, 3/4 kilometer to the northeast.

View. of iron stained outcrop associated with IP targets on line 3. Page 45

One large and two small IP chargeability anomalies occur along

Line 4.

The location of the line is shown in Figure 1. The line is one

mile long and exhibits apparent resistivities of about 200 0hm.m.

Resistivities fall to less than 50 0hm.m in the center of the line,

owing to near skrface conductive overburden, and rise to over 600 0hm.m in the southwest. The reason for the increase in apparent resistivity is not obvious since the first horizontal derivative of the airborne VLF data gives a positive anomaly indicating weakly conductive material. Clearly the VLF and apparent resistivity data yrrr' are reflecting different material, possibly because of differences in depth penetration between the two methods.

In common with the preceding Line 3, the chargeability

background of Line 4 is less than 2mV/V rising to 20mV/V at its western extremity at anomaly C and to almost 6mV/V and slightly greater than 6mV/V at Anomalies D and E respectively.

Anomaly C ranks as a top priority anomaly reflecting a flat lying chargeable zone within 20m of surface. The chargeability zone has relatively high resistivity, falls on a magnetic gradient interpreted to be an intrusive contact zone, and correlates with a

-27- ~

Page 46

distinct Cu, As and Au anomalous geochemical zone. In addition w there is a coincident VLF quadrature anomaly which may or may not be significant. However, because of the striking correlation of anomalous geochemistry and high chargeabilities there is an excellent probability that the IP anomaly reflects sulfides which carry at least some gold and copper.

Anomaly D is considerably weaker and results from a deeper zone of weakly chargkable material. Apparent resistivities are moderately low and there is no obvious, associated geochemical anomaly. However, auriferous pyrite frequently produces similar IP

responses to this anomaly and it deserves consideration as a future

' drilling target.

\ CCI Anomaly E occurs at the end of the line and remains unresolved I owing to the severity of the topography. There is the suggestion of a correlating VLF anomaly, but no geochemical response. Further work on this anomaly will probably depend on the results obtained from the next phase of exploration in which the other IP anomalies will be evaluated.

As with Anomalies A and B on Line 3, Anomaly C merits trenching and further IP lines should be conducted to establish strike extent and direction of all three anomalies on this line, prior to dri 11ing .

VII. GEOCHEMICAL RESULTS ASSOCIATED WITH IP LINES W

Following the encouraging results of the June, detailed soil sampling program, additional geochemical samples were collected in

July, 1989 in conjunction with the reconnaissance induced

polarization (IP) survey of Areas 1 and 6. Additional soil samples were collected at each IP station (50m spacing), and infill soil and rock chip samples were taken in priority areas in order to provide

more complete geochemical coverage. Figure 1 shows both the

locations of the samples collected in Area 6 during the initial Phase I1 grid sampling program in June, as well as the additional

samples collected at the time of the IP survey in July. Figure 1

also shows the locations of samples along IP lines 1 and proposed IP w. line 2. In view of the discouraging IP results on Line 1, line 2 was subsequently dropped from the reconnaissance IP survey in order

to concentrate on the higher priority Area 6, to the north.

All samples were analyzed for gold, silver, copper, arsenic and antimony.

Lines 1 and 2, Area 1

The results of the analyses of the soil samples collected along these lines show anomalous gold values at the northern ends of both

sample lines, the highest value being 30 ppb Au from Line 2. All 1111’ -29- values of silver, copper and antimony are at background levels in W this area except for one arsenic value of 10 ppm located 300m south of the cluster of anomalous gold values.

Line 3, Area 6

Anomalous soil and rock chip gold values were found to correlate with two IP anomalies along the eastern part of this line. A series of rock chips s'amples from an outcrop near the western most of the

two IP anomalies contained gold values of up to 136 ppb with copper

values generally greater than 300 ppm. Rock chip sample GR-12

contained 560 ppm As; nearby rock chip samples yielded copper values

of 380 to 650 ppm Cu. Soil samples along the IP line also produced w elevated gold values immediately west of the western most IP anomaly.

Line 4, Area 6

The IP anomaly located on the western end of line 4 coincides with a series of soil samples which include anomalous values of copper and arsenic and elevated values of gold over a distance of

some 660m. Gold values are less than 10 ppb along this line but

anomalous copper values range from 85 to 190 ppm Cu. Anomalous

arsenic values range from 8 to 24 ppm. The western end of this IP line becomes a prime exploration target in view of the correlation between the geochemical and geophysical anomalies. w -30- w Anomalous gold, copper and arsenic values are identified through an area of exposed oxidized chert outcrop immediately north of Word

Creek in an area between IP lines 3 and 4. Extensive rock chip sampling in this area during the June program showed that the

elevated values reflect outcrop as opposed to the background values over areas of thicker soil cover to the west. No anomalous gold values were found in these rock chip samples.
