SUMMARY

Dorchester Resources Inc. holds a contiguous group of five unpatented

mining claims covering about 80 hectares in Casson Township. The claims are

situated on the southwestern shore of Frobel Lake, approximately 45 km north of

Thessalon and 75 km east of Sault Ste. Marie, Ontario. The property is easily

accessed by fixed-wing aircraft equipped with floats or by a footpath running east

of Highway 129 north of Thessalon, Ontario.

Linecutting, detailed mapping and sampling undertaken on the property

has delineated a calcite-barite vein with a known strike length of over 400 m and

widths varying between 3 m to 20 m. The vein has been hydrothermally emplaced

and has acted as a cement for the breccia of the Frobel Lake Fault. The vein is

compositionally zoned and is comprised of a calcite-barite inner zone flanked on

either side by a quartz vein and fault breccia zone. The calcite-barite portion of

the vein varies in width from 3 m to 15 m.

The vein was sampled using two methods. Firstly, east of LO+00 where

channel samples were impractical, a composite of grab samples was taken across

strike. In addition, channel samples were taken west of LO+00 and located on the

basis of maximum exposure of the vein. A total of 10 channels approximately 13

m apart over 125 m were sampled.

A total of 62 samples were taken and analysed for CaCO^ and BaSO4

weight percent. As the results from sampling undertaken on the property from

the calcite-barite vein have yet to be evaluated, it is not possible to comment on

the economic viability of the potential deposit. However, the geological mapping

survey has been completed and it appears, should the assay results be positive,

that the overall dimensions of the mineralized zone may be sufficient to support a

moderate scale mining operation.

Upon completion of tabulation and evaluation of the assay data, DMBW

will make recommendations for further work if warranted.

INTRODUCTION

This report, prepared by Derry, Michener, Booth ft Wahl (DMBW) on

behalf of Dorchester Resources Inc. (Dorchester), summarizes the results of the

1988 summer exploration program carried out on the Blind River calcite-barite

prospect, located approximately 45 km north of Thessalon, Ontario. The program

was carried out from July 5th to July 16th, 1988, and consisted of linecutting,

geological mapping and sampling. The linecutting, geological mapping, sampling

and field supervision was carried out by T. B. Dickson, B.Sc., DMBW contract

geologist. The program was carried out under the supervision of P. A. Hartwick,

B.Sc., DMBW staff geologist.

PROPERTY LOCATION. DESCRIPTION AND ACCESS

The Blind River property is located on the southwestern shore of Frobel

Lake in Casson Township, approximately 45 km north of Thessalon and 75 km east

of Sault Ste. Marie, Ontario (Figure 1). Highway 129, extending north from

Thessalon, passes approximately 4 km east of the property.

The property consists of five contiguous unpatented mining claims,

covering approximately 80 hectares, and are listed below (Figure 2):

960423 to 960427 inclusive

The claims were staked by Mr. A. Clark and were recorded

November 12th, 1987. Dorchester optioned the property from Mr. Clark in

November, 1987. The Report of Work is included as Appendix I of this report.

Access to the property was provided by fixed-wing aircraft, equipped with

floats, from the Lauzon Aviation Base in Algoma Mills, Ontario, to Frobel Lake, a

flight of one-half hour duration. Alternatively, access to the property is made by

driving 56 km north of Thessalon, along Highway 129, until it crosses Stoney

Creek. At this point, a gravel road is taken for 0.8 km east, followed by a foot

trail for 1.2 km to Snowshoe Lake, and finally a boat for 2.4 km east and from

there the property can be reached by foot. A small, commercially run hunt camp

located on the north shore of Frobel Lake provided accommodation.

DMBW has not examined title to the claims nor substantiated their

physical boundaries and, accordingly, expresses no opinion as to validity of title

and property description.

TOPOGRAPHY AND VEGETATION

Topography on the property is characterized by numerous steep,

topographically high ridges and cliffs (Figure 3). The lowest point on the property

is Frobel Lake at 381 m (1,250 ft.) above sea level. Away from the lake the

ground rises steeply to a high of over 472 m (1,550 ft.) above sea level, for a

maximum relief of over 90 m (300 ft.). A topographically low lineament,

characterized by swampy terrain and an old stream bed, runs roughly parallel to

LO+00, both north and south of the baseline. From this point the ground rises

steeply, both east and west of LO+00, to a maximum of 472 m. The northwest

portion of the property is relatively flat, although topographically high, and

overlain by a swamp.

Vegetation cover on the property consists of an immature forest

comprised predominantly of coniferous trees and a secondary growth of alders and

maple. Low-lying swampy terrain is characterized by alders and minor coniferous

trees, while topographically high ground is dominated by deciduous trees.

The numerous steep ridges and cliffs, coupled with thick secondary

undergrowth, combine to make access by foot a difficult prospect at best over the

entire extent of the property.

ECONOMICS OF BARITE AND CALCITE

Barite

In North America over 9096 of the demand for barite stems from the oil

and gas well drilling industry which uses ground barite as a filler for weighted

drilling muds. Currently, most activity is centred in the Gulf of Mexico where,

despite the relatively low price of oil, offshore drilling has strengthened over the

past two years. However, because of the long distance from the major drilling

areas, Ontario's deposits are not well located to compete in these markets.

Additionally, both the United States and Mexico currently produce approximately

10 times that produced in Canada and are better situated relative to the major

drilling areas.

Non-drilling applications for barite continue to provide a low volume

demand and it is within these markets which Ontario's deposits must compete.

While these markets have remained steady they are not growing sufficiently to

compensate for the loss of sales to the drilling industry. Also, these industries are

mature and new applications are less likely to develop to stimulate growth in

demand. These filler markets include applications in paint, plastics, glass,

chemicals and automobile uses such as brakes and primers.

Canadian barite production fell to 40,000 tonnes in 1986 after reaching a

four year high of 71,049 tonnes in 1985. Similarly, imports fell from 26,589

tonnes in 1985 to 10,525 tonnes in 1986 (Industrial Minerals, March 1988). The

market for filler grade barites is still present; however, over the last two years,

cheap imports, particularly from China, have forced prices to drop by 2596

(R. Hill, Consulting Geologist, pers. comm., 1988). In May 1988, Industrial

Minerals Magazine quoted a retail price of U.S. $85/tonne for ground barite.

Extender Minerals of Canada Ltd., the only current Ontario producer of

barite, recently quoted a price of Can. S200Xtonne for ground barite grading 9696

purity (R. Hill, pers. comm., 1988).

Galeite

Calcite is used as a filler in paint, plastic, rubber and paper. The physical

properties of calcite are important in determining the value and application of

calcite as a filler and include: chemical purity, colour, low abrasivity, stable pH

and good grindability. A high calcium lime plant in Spragge, Ontario, has

reportedly expressed an interest to the property vendor in purchasing calcite from

the property. In May 1988, Industrial Minerals Magazine quoted the price of

uncoated calcite at U.S. S52 to U.S. SSO/tonne.

PROPERTY EXPLORATION HISTORY (After Siemiatkowska, 1977)

The Toronto Assessment Files Office has very poorly documented

information concerning the past exploration history of the property. Apparently

data on drill logs, drill hole and trench location maps were not submitted.

The first recorded work conducted on the property consisted of a

geophysical EM survey, which served to delineate a conductive zone 1,500 m long

corresponding to the Frobel Lake Fault, and a 179 m diamond drill hole to test

this anomaly. This work occurred in 1968 and was conducted for F. M. Jowsey

Ltd.

In November 1968, the property was optioned by Aggressive Mining Ltd.

who, in 1969, drilled a 370 m diamond drill hole intersecting appreciable

disseminated chalcopyrite. In 1970, the company conducted a ground

electromagnetic Crone-Radem VLF survey which revealed the presence of five

conductors. Any results from this work, however, were not recorded.

In 1971, the claims were transferred to Process Minerals Limited and

C. W. Archibald, and at that time four diamond drill holes totalling 538 m were

drilled to test the conductors which, presumably, correspond to the Frobel Lake

Fault. Hole 71-2, 214 m deep, revealed 0.3096 Cu, 0.1396 Ag and 3.9196 barite

over 2.1 m. In 1972, the company conducted an IP survey and drilled an additional

DERRY, MICHENER, BOOTH ft WAHL

- 5 -

three diamond drill holes totalling 382 m to test the conductors, and a barite

showing. The results from this work were disappointing and some claims were

dropped.

In 1973, the Wakomata Lake area was mapped by Siemiatkowska (1977) on

a reconnaissance scale and included the property presently held by Dorchester.

Grab samples from diamond drill core on the property assayed 1.9496 Cu and

0.01 oz. Au/ton.

In November 1987, Mr. Alex Clark staked five claims which comprise the

present property and were subsequently optioned by Dorchester in

November 1987.

REGIONAL GEOLOGY (After Siemiatkowska, 1977)

The Wakomata Lake area is situated in the Canadian Shield on the contact

between the Superior Province to the north and the Southern Province to the

south (see Figure 4). The Superior Province rocks in the area consist of Early

Precambrian felsic intrusives, predominantly trondhjemite, quartz monzonite and

granodiorite, intruded by porphyritic and amphibolide diabase dykes. Rocks of

the Superior Province form the basement on which the Huronian supracrustal

rocks of the Southern Province were deposited. The Southern Province rocks in

the area consist primarily of metasedimentary rocks, dominated compositionally

by interbedded quartzites, sandstones, conglomerates and siltstone.

The Nipissing Diabase in this area forms irregular bodies, dykes and sills

and intrudes all Superior and Southern Province rocks. It is generally dark green

in colour, fine to coarse-grained, equigranular, and consists of metagabbro,

amphibolite, granophyre and porphyritic metadiabase.

Prominent northwest and east-west trending fracture patterns occur in

the area and are expressed as faults and trends of mafic dykes. The Frobel Lake

Fault and the East Caribou Fault, the former of which occurs on the Dorchester

property, trend northeast and are associated with copper mineralization at the

point where they cut Nipissing Diabase. However, no economically significant

discoveries have been made to date. Also, since the discovery of uranium at Blind

River in the early 1950's, exploration for uranium has taken place in the area,

however, results have not been favourable.

Metamorphism in the area has resulted in conditions indicative of

almandine-amphibolite facies for rocks comprising the Southern Province, and

lower greenschist facies for rocks of the Superior Province.

PRESENT PROGRAM

The summer exploration program was conducted between July 5th and

July 16th, 1988, and consisted of linecutting, geological mapping and sampling.

Linecutting consisted of a well-cut baseline, oriented at 300 O, traversing

the entire property. The baseline was placed in close proximity to known

exposures of the calcite vein in order to enhance spacial control. Stations were

established every 25 m along the baseline to facilitate geological mapping and

sampling of the calcite vein. From the baseline, crosslines spaced 100 m apart,

and oriented at 03O0, were paced and flagged using a hip chain and flagging tape,

with stations established every 50 m. The crosslines allowed controlled access for

geological mapping over the extent of the property. Additionally, in the vicinity

of the calcite vein/fault zone, crosslines spaced 25 m apart and cut 50 m on either

side of the baseline were established to provide excellent control for both detailed

mapping and sampling of the vein.

Geological mapping was controlled by the flagged grid on the property and

by the use of airphotos, where flagged lines were impractical as a result of shear

cliffs. The property was mapped at a scale of 1:2,500 (Map 88-84-01) initially, to

gain an understanding of the spacial distribution of the calcite vein and the

various rock types underlying the property. Subsequent to the completion of

mapping at a scale of 1:2,500, detailed geological mapping was initiated at a scale


- 7 -

of 1:500 (Figure 5) over the extent of the calcite vein. This comprised an area of

150 m in length and 50 m in width.

Sampling on the property was undertaken using two methods. Firstly, a

composite of grab samples was taken over the extent of the calcite vein east of

LO+00. This method was used as the exposure of the vein outcropped along a

pronounced cliff, and channel sampling would have been impractical. Samples

were taken approximately 25 m apart. The second method used involved channel

sampling on exposures of the calcite vein west of LO+00. Channels were spaced

approximately 13 m apart from LO+00 to L1+25W and located on the basis of

maximum exposure of the vein. Grub hoes were used to remove overburden and

expose a continuous channel across the vein. Rock chisels and crack hammers

were then used to get a composite of grab samples taken at 2 m intervals across

the channels. Samples were taken only from the calcite vein proper and no

sampling of the wall rock was undertaken. A total of 62 samples were taken

across the vein and analyzed for calcium carbonate (CaCO^) weight percent and

barium sulphate (BaSO^ weight percent.

Samples were analyzed by Assayers Ontario Limited in Toronto, Ontario.

CaCO3 weight percent was analyzed using the acid extraction (HC1-ICP) method

and BaSO4 was analyzed using the lithium metaborate fusion-ICP method. Both

methods are recognized as being both accurate and cost efficient.

PROPERTY GEOLOGY

Lithostratigraphy

Geological mapping conducted over the extent of the property has

distinguished four distinct lithological units (Map 88-84-01). A description of each

with comments on the local stratigraphy follows. Rock classifications are field

names only and no thin section or whole rock analyses were undertaken to confirm

the rock types.

The oldest rocks on the property are granitic in composition (Unit 1) and,

according to Siemiatkowska (1977), are of Early Precambrian (Archean) in age. In

hand sample, the rock is leucocratic and varies from pink to grey in colour and is

medium to coarse-grained with an equigranular texture. Texturally, the rock is

massive and only rarely exhibits a weak foliation in proximity to intruded mafic

bodies. Compositionally, the rock contains 596 mafic minerals on the average and

appears to be most representative of a trondhjemite or quartz monzonite.

Bedrock exposure is mainly in the form of low-lying, large scattered

outcrops and the unit underlies approximately 7096 of the property, predominantly

on the western and central portions.

A porphyritic diabase dyke (Unit 2) occurs to a very limited extent in the

southwestern portion of the property where it is observed to intrude the older

granitic rocks. The unit consists of a fine to medium-grained, dark green ground

mass with anhedral plagioclase(?) phenocrysts up to 3 cm in diameter. The unit is

not magnetic. Contacts with the granitic rocks (Unit 1), where observed, are

sharp and exhibit a fine-grained chill margin. Although the rock is massive it

should be noted that close to the contact with the granitic rocks it intrudes, the

plagioclase phenocrysts exhibit an alignment parallel to the margins of the dyke.

The Nipissing Diabase (Unit 2a) forms an irregular-shaped body and

occupies the central and eastern portions of the property. It is erosion resistant

and, as a result, generally outcrops along prominent ridges. In hand sample, the

rock varies from fine to coarse-grained, exhibits a mottled, dark green-grey-black

colour and is equigranular. The unit is massive and in contact with granitic rocks,

where observed, exhibits chilled margins.

A distinguishing factor of Unit 2a from that of Unit 2 is its moderate to

strong magnetic response and variable composition and texture. Generally, the

rock may be classified as a metagabbro or altered diabase; however, proximal to

the Frobel Lake Fault, granophyre and fine-grained amphibolite phases were

recognized. According to Siemiatkowska (1977), the Nipissing Diabase is of

Middle Precambrian age and, although not observed on the property, intrudes the

older porphyritic diabase dykes (Unit 2) within the region.

DERRY, MICHENER. BOOTH a WAHL

-9-

A carbonate-quartz-barite vein (Unit 3) occurs in a shear zone which

trends the length of the central portion of the property in a northwesterly

direction. This vein, exposed continuously in outcrop for more than 400 m, fills

and cements the breccia of the Frobel Lake Fault. It occurs within, and is

restricted to, the Nipissing Diabase (Unit 2a) and post-dates all other rock types

on the property. In hand sample, the rock varies drastically in colour ranging

from white to beige, grey to light pink and green. The unit is fine to coarse-

grained; in some zones rhombs of calcite and/or siderite more than 3 cm are

common. It is strongly sheared with a well developed cleavage.

To the east of baseline 0+00, Unit 3 is exposed along a prominent steep

ridge and varies in width from 3 m to 8 m. Contact with a fine-grained chloritic

amphibolite wall rock is sharp. To the west of baseline 0+00, the vein is well

exposed due to the downcutting, or karsting, effected by a small stream which

cuts through the vein. In two zones, traversable caves have been formed by this

weathering. The vein varies in width from 10 m to 20 m west of the baseline and

the excellent exposures of the vein exhibit well its compositional zonation. This

zonation will be discussed in more detail in the mineralization section of this

report.

Structure

All rock units underlying the property, with the exception of the

carbonate-quartz-barite vein (Unit 3), are massive with no internal structure. The

trend of diabase dykes, jointing patterns expressed within individual units and

contacts between the diabase dykes and the rocks they intrude, are indicative of

the regional tectonometamorphic structural trend affecting the region as a whole.

This trend is northwest with measurements varying between 3000 and 3300.

The major structural feature on the property is the northwest trending

Frobel Lake Fault. It traverses the length of the property and has been shown by

Siemiatkowska (1977) to extend well beyond the property limits. This structure

provided the environment for focused fluid flow which deposited the carbonate-

DERRY, M ICHENER, BOOTH a WAHL

-10-

quartz-barite vein which has acted as a cement for the breccia of the Frobel Lake

Fault. This hydrothermal vein has undergone intense shearing and exhibits strike

measurements varying between 305 O and 320 O, with dips to the southwest between

750 and 8Q 0.

Mineralization

Mineralization occurs in vein form and consists of calcite and barite

restricted to Unit 3. East of the baseline, no occurrences of barite were

encountered and the vein is composed of white to grey calcite varying in thickness

from 3 m to 8 m. It outcrops along a steep ridge and is exposed in outcrop along

strike for over 200 m. The wall rock is a fine-grained amphibolite which grades

into an altered diabase away from the contact.

West of the baseline, the vein is exposed for over 125 m and varies in

thickness from 10 m to 20 m (refer to Figure 5). It is presumed the vein continues

northwest from its last exposure; however, extensive overburden and swamp cover

afford no outcroppings.

Due to excellent exposures of the vein in this vicinity, caused by the

downcutting of a small stream, the mineralization in the fault zone appears to be

compositionally zoned as follows:-

Hanging Wall - Nipissing Diabase (Altered Diabase)- Quartz Vein and/or Fault Breccia Zone- Impure Calcite Zone- Pure Calcite Zone- Calcite-Barite Zone

Footwall - Fault Breccia Zone- Quartz Vein

Nipissing Diabase and/or Granophyre

The calcite-barite mineralization within the vein is restricted to the

"inner" portion of the vein and varies from 10 m to 15 m in thickness. Calcite,

with minor amounts of siderite, ranges in colour from white to beige, grey to light


-11 -

pink and green. It is fine-grained, however, there are restricted zones of coarse-

grained calcite with rhombs up to 3 cm in diameter. Barite, although difficult to

distinguish in hand sample, appears to be restricted to a thin zone proximal to the

footwall breccia over the length of this exposure.

The footwall breccia is a fine-grained, friable, dark green rock which has

been chloritized and is vuggy. It contains numerous quartz-carbonate angular

fragments and stockwork veinlets. The quartz vein flanking the calcite-barite

zone is white to smoky-grey in colour and barren of any sulphide mineralization.

Sulphide mineralization is restricted to Unit 3 and altered diabase (Unit

2a) in proximity of the Frobel Lake Fault zone. It consists of anhedral blebs of

chalcopyrite grading up to 196 locally within the carbonate vein and, to a lesser

degree, fine-grained disseminated pyrite. Locally malachite was also noted in

trace amounts within this unit. Pyrite and/or pyrrhotite occurred in trace

amounts in altered diabase proximal to the fault zone. Sampling was restricted to

the calcite-barite vein and no sampling of the wallrock was undertaken. Assay

results are currently being compiled and evaluated.

DISCUSSION OF RESULTS

As the results from sampling undertaken on the property from the calcite-

barite vein have yet to be evaluated, it is not possible to comment on the

economic viability of the potential deposit. However, the geological mapping

survey has been completed and it appears, should the assay results be positive,

that the overall dimensions of the mineralized zone may be sufficient enough to

support a moderate scale mining operation. The strike length has been traced for

over 400 m and widths vary from 3 m to 15 m. To put this in perspective, it is

pertinent to review the geology of Extender Minerals of Canada Ltd.'s barite

deposit in Matachewan, Ontario. This is the only currently producing barite mine

in Ontario and has a production rate of 25,000 tonnes per annum from its

underground operation. The deposit consists of four separate veins averaging 4 ft.

in width and 800 ft. in strike length. Grades vary between 096 and 9596 BaSO4

with an average grade of 5096 to 6096 83804. All mining activities occur above


-12-

the 300 ft. level (R. Hill, Consulting Geologist, pers. comm., 1988). A comparison

of the dimensions between the two deposits easily demonstrates that, in terms of

tonnage, the potential exists, if grades are sufficient, for an economically feasible

operation on the Frobel Lake calcite-barite prospect.

CONCLUSIONS AND RECOMMENDATIONS

Upon completion of tabulation and evaluation of the assay data, DMBW

will make recommendations for further work if warranted.
