(i)EXECUTIVE SUMMARY

The 1992 Ontario Prospectors Assistance Program (OPAP) Funding was directed towards Investigating a vell-documented but little explored area for Mississippi Valley Type (MVT) potential in Tudor Township, Grenville Province of Southeastern Ontario within the Eastern Ontario Mining Division.

Six unpatented mining claims, referred to as the Millbridge property, were staked at latitude 44 degrees 50 minutes North and longitude 77 degrees 50 minutes Vest, Concessions II and III, Lots 21 - 24, to examine Zn/Pb mineralization for similarities to typical MVT economic mineralization and explore for possible such occurrences within the property's boundary. This technical report summarizes the initial findings of this preliminary exploration.

Generally, the Millbridge property lies: approximately 24km (14.4mi) NHV of Madoc, 45 km (28ml) southeast of Bancroft and 485 km (291mi) northeast of Toronto within the Grenville Province of the Eastern Ontario Mining District, Ontario.

The Grenville Structural Province constitutes the southeastern margin of the Canadian Precambrian Shield and trends northeasterly in excess of 1,000 miles (figure 1). Notably, it is the youngest orogenic province within it; the Grenville Orogeny K/Ar dates 1000 m.y. Within the Province, several subprovinces known as Belts exist and it is within the Central Belt that the Millbridge project lies (figure 2).

The Central Metasedimentary Belt (CMB) hosts several Pb and Zn occurrences including the past-producing economic zinc deposit. Long Lake Mine, thought to be controversially a MVT and an extension of the northeasterly MVT deposit trend from Tennessee, USA. Historically, this SW portion of the CMB was regarded as the faulting zone locus, the site of dramatic change from low grade metamorphics to high grade gneisses (figure 3). Subsequently, the Grenville Orogeny affected all rocks metamorphosing them to a high degree of metamorphism with the exception of those of the Hastings Basin near Madoc. It is here in the Bancroft-Madoc area, both high and low grade metamorphism, exist in the Grenville Province. Within the Grenville, geology remains poorly understood with many areas incorrectly mapped. Generally, orthogneiss, paragnelss, marble and metavolcanic rocks underlie the region.

Very minimal previous work has been experienced within the subject area.

(li)

Exploration, OPAP'92, consisted of a cursory analysis of: prospection; flagged grid employment; surveys of geology, geochemistry and VLF-EM geophysics; and limited litho-sampling. This preliminary work has resulted in several geochemical Pb/Zn anomalies and geophysical conductors which require further investigation.

Although fluid Inclusion studies are necessary to qualify positively whether MVT Pb-Zn deposition is operative on the Millbridge property, further investigation, probably to the diamond drilling stage theorized to the MVT is required.

It is thought that further and Intensive exploration on the Millbridge property will afford a better understanding to the Grenville as an entity.

1.0 OVERVIEW:

A study of Mississippi Valley Type Mineral Deposition in the Grenville, Ontario

Definition:Mississippi Valley Type deposits are formed in carbonate rock

from formation fluids at low temperatures and depths.

Model of Deposition:1. Deposition of a limestone host and a shale source formation.2. Development of caverns and porosity in the host by karsting

during an erosional event.3. The host was buried more than 4,200ft beneath an unconform

able cover.4. Two formation fluids carrying metal and sulphur ions migrated

to the caverns and precipitated galena and sphalerite at low temperatures, 52 to 105 degrees.

Ground preparation is an important, in fact, essential feature with favourable porosity often facies-controlled. Consequently, an in-depth understanding of the host rock is equally as important in exploration as detailed studies of the ore showings themselves. The chosen area of interest north of Madoc comprises a small portion of the carbonate platform - basin margin sequence in the Grenville.

Since every carbonate platform sequence has the potential to host MVT mineral deposits, an understanding of the ore-forming mechanism is essential. The carbonates themselves can supply at least a portion of the metals needed, even minimal tectonism can greatly augment the supply by tapping adjacent systems and chloride complexes that carry them. Sulphur is present in large amounts as sea-water sulphate and the bacteria necessary for reduction abounds in the host environment. Conditions facilitating precipitation such as changing Eh-Ph parameters and mixing of solutions occur routinely during diagenesis while variability lies in the timing and the availability of metals. Reservoirs of oil/gas are found associated with MVT deposition.

The geology of the region has been extensively studied yet its petrology and stratigraphy as well as the effects of regional metamorphism are still quite controversial. Comprehension of the reasoning is difficult when a multitude of mineral deposition types exist within a limited localized region, of the Grenville.

1.1 Review of the Grenville, Southeastern Ontario

Research completed by the University of Western Ontario in 1972-3 indicated that possible interpretation of paleomagnetism of rock samples in the southern Grenville suggested that the southern part of the Grenville province was formed some 30 degrees SE from its present position, several thousand kilometers from its present position. This provides persuasive evidence for late Proterozoic continental drift.

The Central Metasedimentary Belt (CMB) of the Grenville Province consists of marbles, gneisses and metavolcanic rocks that have been intruded by felsic to mafic igneous rocks. Intrusion occurred prior to, during, and after the Grenville orogeny; culminating in the Ottawan orogeny ea. 1090 Ma (Lentz 1991). The CMB forms the northwestern portion of the Grenville Province; it is bounded by the Central Gneiss Belt (CGB) to the north, and the Central Granulite Terrane (CGT) to the southeast, figure 1. The northeast-southwest trending CMB boundary zone is the boundary between the CMB and the underlying CGB; it dips to the southeast at a low angle.

Underlying the CMB, rocks of the Bancroft Terrane are middle to upper amphibolite facies, approximately 650 C degrees, whereas rocks along the NW- and SE margins constitute the upper amphibolite to granulite facies. Thermal denudation studies imply that the Bancroft Terrane remained above 500C degrees between 1100 and 980 Ma allowing granitic pegmatites to form during this period when host-rock temperatures were approximately 500 C degrees, ea. 1020 - 1050 Ma. These granitic pegmatites are associated with veins and skarns mineralogically similar to regional metamorphic assemblages. This suggests that the adjacent Elzevier Terrane, ET, experienced similar phenomena with similar fluctuation of host-rock temperatures.

Several types of metallic mineralization have been defined within the Grenville Province:

1. stratiform zinc in carbonate rocks2. stratabound pyrltic (-t base metal) sulfides in volcanic and

sedimentary host rocks3. gold-quartz veins4. quartz-magnetite ironstone5. copper-nickel and iron-titanium concentrations in intrusive

rocks6. iron skarns7. molybdenum in skarns and pegmatites8. uranium and thorium in pegmatites,veins and calc-silicate

gneisses9. hematite veins10. magnesium in dolomitic marble11. barite-fluorite-celestite-galena in calcitic veins

(after Carter).

1.1 Review of the Grenville, Southeastern Ontario cont'd.

These metallic-type depositions are believed originated from four genetic processes:

1. Syngenetic processes related to volcanism and sedimentation2. Epigenetic processes related to diagenesis, regional metamor

phism, and igneous activity3. Magmatic processes related to igneous intrusion4. Supergene processes (after Carter).

In the Central Metasedimentary Belt the environment of these syngentic volcanic/sedimentary and epigenetic mineralization is shown in figure 4, after Carter.

1.1 Review of the Grenville, Southeastern Ontario cont'd.

Carter (1984), states that the following are deposit types of the Grenville correlative to major producers elsewhere:

1. sedimentary exhalative lead-zinc (stratiform zinc?)2. lode gold (gold-quartz vein)3. volcanogenic, exhalative Cu-Ag zinc (statabound pyritic

sulphides)4. contact metasomatic iron5. magmatic Cu-Hi and Fe-Ti

It is noted that significant production has been realized from the Central Metasedimentary Belt of the Grenville, examples being:

1. Hilton and Marmoraton contact metasomatic iron deposits2. Kingdon lead-vein deposits3. Cordova and Deloro gold deposits4. Balmat-Edwards and Long Lake stratiform zinc deposits5. Madawaska (Faraday) uranium deposit6. New Calumet Zn-Pb-Ag volcanogenic exhalative deposit7. Chromasco magnesium deposit

Within the CMB, the greatest potential appears to be for stratiform zinc, pyritic base metals and gold-quartz vein type of deposition. Theorization and definitive classification of MVT mineralization has yet to be resolved.

1.2 Review of Mississippi Valley Type (MVT) Deposits

Generally, MVT deposits are epigenetic, carbonate-hosted lead- zinc deposits formed in sediments during the history of a sedimentary basin; sphalerite and galena are characteristic and formation is in shallow water experiencing diagenesis, very low temperatures and 80 - 200 degrees C. Usually, the deposits are stratabound with few exceptions located generally in undeformed platformal carbonates.

Table l summarizes common characteristics of MVT deposits.

Although MVT deposits occur in Canada le. Gayna River, H.W.T., they, in fact, form the principal source of lead and zinc in the United States. Tennessee is the most prolific of the four districts in the United States hosting these deposits.

2.0 PROPOSAL

A proposal was submitted to the Ontario Prospectors Assistance Program to investigate Pb - Zn exploration for Mississippi Valley Type deposits in S.W. Tudor Township, Hastings County, Southeastern Ontario. Direction towards this type of mineral exploration has been Investigated and herein documented.

2.1 Area of Interest

Six unpatented claims, claim number 1191076, in Concessions II and III, Lots 21 - 24 west of Hastings Road.

2.1.1 Location

Six unpatented 3400'x 700* claims known as the Mlllbridge property were staked in the spring of 1992. These claims are located in Lots 11 fi 12, Cone. II and III west of Hastings Road, southwestern Tudor township, NTS 31C / 12ME, figure 5. Specifically, these claims lie within the Elzevir Terrane, a tectonic subdivision of the Central Metasedimentary Belt (CMS) of the Grenville Province of Eastern Ontario. Generally, the property lies approximately 44 km. (26mi) SB of Bancroft, 22 km (13mi) NNW of Madoc and 362 km (225 mi), as the crow flies, east and north of Toronto, figure 5.

2.2 Topography

Topographically the property and surrounding immediate area is unremarkable. Air photo interpretation of the general region indicates a consistently unremarkable geomorphology; terrain is moderately rolling, no major interruption is noted. The major glacial type of deposit within the Grenville, a typical morainic development, is observed in the general area.

Rock outcrop exposure is minimal; forested vegetation almost entirely predominates. This vegetation consists of: spruce, hemlock, poplar, beach, birch, cedar, balsam, pine, cherry and ironwood.

Evidence of glacial sequelae suggests a NE-trending glacial retreat; South 4-6 degrees V. No unusual phenomena was observed relating to effects of glaciation.

Glacial deposits in the area consist of till which is commonly gravelly to sandy loam comprising the ground moraines and drumlins. It is observed that overlying the marble bedrock brown soils predominant.

2.2 Topography cont'd.

Low-lying areas are converted to bogs; muck soils and peat comprise these swamps.

Only one river system occurs in the immediate area dissecting the lower SV portion of the property. This river, the Jordan, trends in a general north-south direction flowing to a more NW direction as it approaches the road Intersection. A good deal of swampy area occurs along the river and to the immediate region.

3.0 GEOLOGY

3.1 Property

The Millbridge property constitutes the southeastern portion of the Central Metasedimentary Belt within the Elzevir terrane tectonic subdivision. Within this Elzevir terrane, the Hermon and Mayo Groups, predominantly volcanic and carbonate sedimentary rocks with intercalation of siliceous clastic units have been defined. This Proterozoic metavolcanic-metasedimentary sequence is 27,000ft (8,230m) thick and has experienced regional metamorphism to the greenschist facies. Following regional metamorphism the entire sequence was folded about a northeast trending axes; oldest exposed rocks display the lowest grades of metamorphism. This northeast trend is prevalent on the property.

The property is underlain by predominantly limestone/marble with minor interbedded metagreywacke and actinolite metasediments trending generally in a northeast direction. A reconnaissance geological survey of the property was completed and the results of this work are found on drawing 13. Interpretation is enhanced by use of the completed VLF-EM 16 survey, however, it is complicated by the presence of swamp and bogs.

Generally, rock exposure was good on hills and poor in low-lying areas. The overlying soil development apprears independent of: 1) underlying basement rock and 2) conductor/soil anomaly Pb and Zn areas. Two directions of country rock fabric was observed although the predominate direction is northeasterly: a N to NNE- trending east-dipping, (45 -68 degrees) and NW- trending northerly dipping sequence of rocks. The southeastern portion of the property exhibited numerous strike and dip variations indicating anticlinal/synclinal structural development as an operant. Geology Report 67 documents the presence of regional structures: the Millbridge and Jordan Creek Synclines which are separated by an anticline in the south-central region of Tudor Township.

The preliminary geological survey revealed several structural characteristics that suggest additional regional structure. The 14 foot (4.3m) long, 8-12 inch (20-30.5cm) wide joint trending in a northwest-southeast direction discovered at 5+OON, L10W suggests pervasive fault presence; detailing is required. Joint sites are preferential to the blue/grey limestone/marble which exhibit a coarse-grained nature. The southeastern portion of the property tends to project itself as one influenced by anti- synclinal development; this also requires detailing. Both of these characteristics are evaluated as potential fluid pathways for mineralization. Field work indicates potential for replacement and/or stockwork deposition.

3.1 Property cont'd.

The grey/blue limestone/marble, mostly impure, exhibited variability throughout the property. It ranged in composition from sandy to silty, foliated to massive fine-to-medium-to-coarse grained texture. In several areas, it was extremely crystalline with considerable phlogopite and chlorite presence. In one area, tremolite was observed. It exhibited contact metamorphism in numerous areas; this was observed by the granoblastic, hornfelsed texture of the coarse-grained marble, photo 1. Calcite veinlng was complex and contorted in especially two areas: east- central and southwest corner of the property, photo 2. These veins exhibited the appearance of fissure veins filling extension fractures and joints in other areas, photo 3 and 4. Pyrite disseminations and fine-grained euhedral crystals were found preferential to this rock unit.

The clastic siliceous metasediments comprised of mainly feldspathic metagreywacke altered in many cases by iron oxide and sulphide staining, photo 5, and 6. A rhythmic bedding, photo 7, was noted; this exhibited intercalation with meta-arkose layers. The meta-arkose presented as medium to thick bedded with predominantly medium-grained quartz, some chlorite and mica. The prophyroblastic actinolite metasediments where observed presented as foliated, mostly dark green rocks generally difficult to distinguish from the metagreywacke. Just north of the baseline in the central portion of the property at the river, several quartz pods mostly bull quartz and veins were observed; an onion- skin texture was prevelant, photo 8.

The presence of granite requires further investigation.

3.2 Mineralization

The government Geological Data Inventory Folio, 6DIF 84, report and regional geological map indicate presence of the following:

1) Pb, Cu, tourmaline occurrence just west of L4w, about 4S.2) Au occurrence on the eastern property boundary at 3+003.3) old ddh., 61.7 feet in length with py, po reported at

approximately LlW, 5+50S.4) old ddh. situated at L8+50V, approximately 3+50S, 56.6' in

length; cpy, py and po are documented.

The following observations are noted to the aforementioned:1) This Pb, Cu occurrence is supposedly present in underlying

blue/grey limestone, marble. No such mineral occurrence was observed or suggestion thereof; no geophysical or geochemical response is associated in the area of this documented occurrence.

2) No suggestion of possible Au occurrence was noted or any structural phenomena seen to suggest such presence.

3) No identification of this ddh was made in the field. No sulphide presence noted in the immediate area and no explainations can be given for its presence.

4) Again, this drill hole, although not long enough, could exist in the western extension of Anomaly i4.

Possible NE-trending syncline/anticlinal structure is interpreted with an accompanying NE-trending and a N-trendlng fault presence in the SB portion of the property.

It iB observed that there is an intensity of quartz float and veinlet presence at the southern property boundary extending from L10W to approximately L4V. Because of the wire fence presence, VLP-EM results are deemed inconclusive. However, it appears that a large conductor is present about the entire southern property boundary.

-.

Ankerite was particularly prevalent in areas of quartz velning. No considerable quartz vein widths to be economically viable as a host of gold was discovered. Commonly, this veining was found in the blue limestone and observed to have only minor fracturing and sulphide presence exhibiting no unusual alteration. In the southwestern portion of the property quartz veining appeared to reflect slumping, photo 1. Where wider sections of quartz were noted and in places blowouts, the quartz remained only up to 1/Bth of an inch wide yet sheetlike.

A conspicuous and predominate presence of pyrite mineralization is noted throughout the property. Ubiquitous, euhedral crystals of pyrite conjunct massive crude layered streaks paralleling bedding are disseminated throughout the lithology especially within the fine- to medium-grained marble. It commonly forms less than 2 percent of the veinlets where it occurs as disseminations and irregular blebs. Disseminated pyrite also forms up to l percent of the intervening limestone/marble and less of the calcareous feldspathic metagreyvacke.

Additional mineralization observed during field work included:1) Possible fluorite, in one isolated location of the NE area of

the property.2) Grey hematite along fracture planes in quartz float about

L7V, 6+OOS and rare instances within quartz veining.

The restricted nature of this mineralization does not appear to undergo a subfacies change but rather appears structurally dependent.

153.2 Mineralization cont'd.

ALTERATION:Contact metamorphism is delineated to a zone within the north and south periphery of the property and is predominantly observed within the limestone. The obvious characterization is the presence of hornfels. Silicification, hematization, seritization and carbonatization are major operants; ankerite and chloritization remains a minor component. The field notes expound on their nature ie. black chloritoid in the metagreywacke.

3.3 Regional

O.D.M. Map 2168, Tudor Township, indicates the immediate surrounding area's regional strike to be northeast having three separate dips: 1) ranging between 65 to 85 degrees to the SB 2) vertical and 3) 55 to 80 degrees to the NE. A moderately lengthy anticline which trends northeasterly through Mlllbridge Station extends southwesterly through the property. A regional northeasterly trending syncline occurs immediately south and east of the OPAP property.

A rock sample was taken for Pb and Zn assay from the Mono Mines Ltd. property immediately southeast of the Millbridge property. Analysis showed ISppm Pb and llppm Zn.

About L9V, 1+0ON an old northerly trending elliptical trench underlain by blue/grey limestone-marble countryrock was discovered, litho and soil sampled. Soil sampling reported 19ppm Pb and 114ppm Zn, rock sampling returned assay results of 23ppm Pb and 65ppm Zn. These results do not explain the existence of the old trench.

4.0 PREVIOUS WORK

The general area of Tudor Township has been napped by Lumbers, 1969, and reported to host more than 32 Pb-Zn showings, most experiencing activity in the 1800's and early 1900. Specifically, the unusual number of Pb-Zn showings within the carbonate rocks of Tudor Township are reported to strongly correlate with the base of the carbonates proximal to their contact with clastic sedimentary rocks.

The Millbridge property hosts two documented occurrences: 1) V. Wright lead occurrence. Lots 11 t 12, west of Hastings Road and 2) Blackburn, Lot 11, Cone. II, Great Indian Explorations Ltd.

The Wright Pb occurrence found on government map 2168, No. 19, consists of galena-calcite veins. The calcite and quartz fissure veins trend WNW. In 1960, two short diamond drill holes encountered a few narrow quartz veins containing minor disseminated pyrite and traces of chalcopyrite. One of the setups was discovered immediate Hastings Road and the baseline, however no galena/calcite vein structures were encountered. This lead occurrence is documented as being similar to the Ramsey Occurrence, Lots 11 S 12, East of Hastings Road. Quartz veins containing tourmaline, minor calcite and sparcely disseminated pyrite are confined to 100' thick unit of Interbedded feldspathic metagreywacke and porphyroblastic actinolite metasediments which trend NE. A drusy calcite vein less than two feet wide contains barite and disseminated coarse grained galena crystals at the contact of fine grained marble and thin calcareous feldspathic metagreywacke unit. No evidence of this type or mode of mineralization was found.

The Blackburn/Great Indian Explorations Ltd. mineral occurrence consists of a six inch galena/calcite vein. Mineralization is galena in calcite veins that are vertically dipping metasediments of the Dungannon Formation which consists of fine grained marble with minor interbedded feldspathic metagreywacke units less than ten feet thick. Drusy calcite vein material on a dump near the workings contains quartz crystals, barite, galena, chalcopyrite, pyrite and rarely sphalerite. The vein was explored in the 1925 era by a shaft, pit and trench. These were found but the mineralization wasn't.

5.0 GEOCHEMISTRY

5.1 Soil Geochemical Survey

A 25 meter interval along the baseline and a 50 meter interval over the remainder of the property where feasible was used in this survey. Generally, a 2.5 foot depth attained the 'B* horizon although in many areas adjacent swampy or bog areas in the western portion of the property good soil definitions were not possible. A total of 111 samples were taken and assayed for Pb and Zn.

5.2 Analytical Methodology for Soil Geochemistry

Soil samples are carefully prepared prior to analysis using the following steps.

1. samples are received and put into numerical order or line order and recorded

2. samples are then put into a hot air drying oven and the temp is carefully controlled to ensure each sample is thoroughly dry

3. each sample is placed in a fSOmesh screen and set on a sieve shaker for ten minutes

4. 100* of -80 fraction is collected and set into a sample can

5. 100* of +80 fraction is collected and bagged for storage in a box marked reject portion

6. 100* of -80 fraction is poured onto a rolling cloth and rolled to ensure the sample is homogeneous

Once completed, the following procedure using a l gram sample portion is employed for elements: Ag, Cu, Zn, Pb, Nl, and Pe.

1. one gram of sample is weighed and placed in 200ml tail form beakers

2. 15ml of concentrated HMO, 70*, is placed in the beaker

3. sample is bulked to 75ml with distilled deionized water

4. sample is digested at 220C or 430C degrees until solution is concentrated to 50ml (approximately 2 hours)

5. an additional 10ml of concentrated HNO3 is added and boiled for an additional two minutes

18

5.2 Analytical Methodology Cont'd.

6. sample is removed from hot plate and cooled to room temp.

7. sample is then balked to 100ml and read on instrument in ppm scale directly

*** Fisher Scientific lOOOppm stock standards are employed for each element. ***

Bach element is calibrated with a 0.25ppm, O.SOppm and l.OOppm standard and results are multiplied by 100 due to the dilution factor. Results over calibration scale are recalibrated with higher ppm standards ie. 5ppm, lOppm etc.

5.3 Results

The highest Zn value, 464 ppm, occurs at Line 9+50 V, 5+10 S vithin an anomously high northwesterly trending area underlain by medium grained blue marble and layered hornfels in the southwest portion o f. the property. Bedding is northeast dipping 50 degrees to the northwest. A river surrounded by low, boggy ground transects this area winding into the extensive west swamp.

The highest Pb value, 440 ppm, occurs at Line 4W, 0+50S and is underlain by feldspathic metagreywacke and meta-arkose. Two additionally high values, 150 ppm and 223 ppm, occur at 1+50S and 2t503 respectively on Line 6W. These three values appear to be the same occurrence, all within a northeasterly trending lineament - creek related structure in the middle portion of the property.

Generally, the property is anomalous in zinc with Pb and Zn values independent of one another. The observed anomalous trend appears to parallel bedding and obviously is structurally controlled. With the exception of the old diamond drill hole found about 150 feet west of the Hastings Road, no previous work as noted by the observed drill setups and pits, lies in anomalous areas.

A high background threshold was obtained over the entire property. Because of this, the anomalous values, Pb, lOOppm and Zn, 150ppm were used to better delineate true anomalies.

Pour northeast trending Zn and/or Pb/Zn anomalies are interpreted from the assay results, drawing 12. Three zinc anomalies are extensive and possess lead anomaly counterparts as well as related geophysical conductors.

Anomaly populations independent of underlying rock type, however, appear to exist within possible local interpreted synclines. This, perhaps, suggests an underlying structure: northeasterly trending channelways of mineralizing fluids.

19 5.3 Results cont'd.

The soil geochemical survey completed over this property resulted in four zinc and/or lead anomalies. They exhibit the following characteristics:

1. ANOMALY 'l 1Anomaly *1* is an extensive, approximately 460 meters in length, approximately 65 - 70 meter wide, northeasterly trending Pb/Zn anomaly straddling the baseline at L2V to 23 at L6W. A structural origin is interpreted.

2. ANOMALY '2'On the adjacent line L6W, also approximatley IN immediately south of the meandering Jordan River two more trenches were discovered. Soil geochemistry results reported an approximate 300 metre and approximate 75 metres wide northeasterly trending Zn/Pb anomaly. This anomaly is interpreted to be associated with the Zn anomaly its' eastern extension found about L2W at approximately H-75H. This eastern northeasterly trending extension is about 250 metres in length and 8 metres in width. An old ddh. exists at about H-75N and 65 metres west of L4W; this hole was apparently drilled south and should of proceeded into the anomaly. Prom the documented data available, it is thought that this hole in fact did not drill the anomaly.

3. ANOMALY '3*A small 'spot high' zinc anomaly exists about 4N on L4V. It appears drawn out northeasterly towards L2W. No anomalous geophysical response was reported.

4. ANOMALY '4*

It is interpreted that this is an extensive Pb/Zn anomaly diagonally transects the southern portion of the property from the eastern most portion of the baseline to the furthest southwest portion of the property. This anomaly is complex; three separate Zn anomalies with only the central one possessing a Pb counterpart. Again, a structural origin is interpreted.

5.4 Discussion

Interpretation of geochemical anomalies in glacial overburden is complicated by the diverse origin and nature of glacial deposits compounded over relatively short distances by variability of depth. Complexities in local deposition and glacial history results in a corresponding complexity in dispersion processes and therefore geochemical patterns. The Millbridge property and the immediate adjacent area has reported numerous zinc and lead syngenetic and epigenetic hydromorphic anomalies. Because of the diverse complexity of these two types of anomalies which Includes consideration of upstream anomalous seepage areas and anomalies

resulting from the weathering of high-background rocks suspected from the large area of the patterns, it was thought adviseable to complete an EM-16 geophysical survey to gain further information.

The primary controls on the localization of economic concentrations of Zn, Pb and/or Au on the Grenville are stratigraphy and structure. Penetrative, ore-controlling faults would have to be repetitively activated in numerous stress regimes over time. Favoured host for MVT mineralization is carbonates and sometimes limestone units with inherent enhanced porosity and permeability. This immediate area does not meet known general conditions that in turn would necessitate shallow basinal, low temperature high pressure conditions to generate substantial economic mineralization.

It is suggested that further geochemical analysis be undertaken on a fill-in basis, every 100 metres, between flagged lines. This will verify and extrapolate present results.

The most Interesting geochemical anomaly is anomaly 'l'; an extensive VLP-EM 16 conductor mirrors this anomaly.

5.4.1 Exploration Suggestions

1. Investigate unconformities within carbonate sequences. Usually economic ore horizons occur below an unconformity.

2. Basement high.

3. Open space development within carbonate sequences. This will be observed via indications of brecciation, carbonate stata thinning and localized increase of insoluble residue material.

4. Reefs.

5. Facies changes in carbonate-shale and limestone-dolomite.

6. Fluid inclusion studies be executed to determine at what temperature the material was precipitated; typical MVT deposits are low temperature.

7. Since the typical genetic model for MVT deposits interprets the brines originating from shale basins adjacent to platform carbonates with the ore minerals precipitated sometimes during early diagenesis and other times long after lithification of host rocks, it would be adviseable to define possible basin-platform structures to explore in.

21

5.4.1 Exploration Suggestions cont'd.

Therefore, the geological setting would tend towards platform carbonate successions commonly located between a zone of tectonic instability characterized by vertical movement. Documentation indicates that this vertical movement is commonly a "hinge line", marked by rapid lithological facies changes ie. sedimentary basin edge or reef front, and the tectonically stable platform (GSC, 1984, p.25).

7. Typical MVT deposits form after basin development, however, it is possible that a new type, a variation of the typical MVT is operative. This model would include basin extension with related fracturing of regional extent; mixed carbonate-siliciclastic sediments would be of prime importance.

8. Carbonate rocks favour zinc-rich deposits and sandstones where lead may be derived from K-feldspar, favour Pb-rich deposits.

6.2 Analytical Methodology

The VLF-EM survey is a very low frequency electromagnetic survey using possible navigation transmitter NSS and MAA signals: Annapolis, M.D., Seattle, Washington, and Cutler, Maine, U.S.A. The dip angle and vertical quadrature to the resultant magnetic field at each station is measured by the receiver to detect presence of conductors at a moderate-to-great depth. The secondary fields are measured as a ratio to the primary field making the measurement independent of absolute field strength.

Resultant data was plotted as stacked in-phase (4-) and out-phase profiles (-, quadrature) and conductor axes Identified using points where the dip angle crosses from negative to positive. Importantly, an incomplete cross-over may occur where multiple conductors distort the primary field strength.

This survey employed a Geonlcs EM-16 unit using the navigation signal Cutler, Maine, U.S.A., NAA 24.0 kHz. Twenty-five metre interval stations were employed. The percent slope of the dip angles or In-phase and quadrature were measured facing north. Specifications for this unit are documented as follows:

6.3 Results and Discussion

Five east-west trending conductors: A, B, C, D, and E were identified on the property, drawing no.l. These conductors reflect the 'IP* phase component crossing from the negative to the positive 'OP* phase and by a sharp decrese in amplitude adjacent to a cross-over.

All five conductors trend about 45 degrees to the property's structural trend with only conductor 'E* not associated with zinc or lead soil geochemical anomalies.

Conductor A:This is the most extensive conductor which is approximately 650 metres (2,132.55ft) in length and straddles the baseline; moderate to strong. It was not tested by the previous drill hole as the hole is 75 metres (246ft) east of the most eastern conductor extremity and not extensive enough in length. It can be traced in excess of 400 metres (1,312ft) over three lines being strongest at L6W; -46, -1-25 to -42, -11 peak to peak.

28 6.3 Results and Discussion cont'd.

Conductor 'A* Is modified by swamp Interference to the vest resulting In a geological conductor response uncertainty; It Is open to the east. It Is Interpreted to be a bedrock conductor dipping slightly to the north.

Conductor B:This Is a weak VLF-EM bedrock conductor In excess of 200 metres (656ft), located traversing lines 4 and 6V immediately north of the baseline about 2N in the central area of the property. The Jordan River affects it to the west. This conductor appears to have been previously drilled.

Conductor C:This is a short, moderately strong bedrock conductor, +16, +S to -28, -10 peak to peak, only present on L4V almost at 3N immediately north of conductor *BN . To the west. It is complicated by the Jordan River and pond. This conductor requires detailing.

Conductor D:Conductor 'D 1 Is a moderately strong bedrock conductor, +17, +S to -32, -20 peak to peak, approximately 260 meters (853ft) in length transversing only L4W at about 23, south of Conductor 'A*. The largest, most extensive northeast-southwest Pb/Zn geochemical anomaly present on the property is associated with it. This conductor requires detailing as well.

Conductor B:This is a complex, weak conductor approximately 125 meters (410ft) in length cutting L2V at about 43. It does not possess a comparable geochemical anomaly of either Pb or Zn associated with It. Although minor, it is felt that even though probably no further work is needed, this however should be investigated.

7.0 CONCLUSION

The principal ore minerals, sphalerite and galena, of typical Mississippi Valley lead-zinc deposits were not observed to occur except In trace amounts. Similarly, the associated minerals of: pyrite, marcasite, dolomite, calcite, and lesser amounts of quartz, barite, fluorite, and chalcopyrite were not found to be consistently present with the exception of pyrite and calcite.

Five VLP-EM 16 conductors, four Pb/Zn soil geochemical anomalies and promising potential-hosting lithology for a contact type mineral deposit was delineated from this preliminary OPAP'92 project. Further Intensive work is required to Investigate the MVT model as an operant underlying this property and surrounding region.

30

8.0 Recommendations

Every carbonate platform sequence has the potential to host a Mississippi Valley Type ore deposit. The complex diagenetic history of such a system ensures the formation of a favourable horizon at least once, if not several times. Investigation of mineral deposits and prospects throughout the Grenville reveals a wide variety of classification types and genesis/modes of occurrence. Formible exploration embrassing deeper drill hole analysis to better understand the area's stratigraphy is thought foremost. Regional geological studies to emphasize the location of major structures active in the past which could control migration of hydrothermal fluids and which possibly Influenced sedimentation in the sequence of overlying potential host rocks is important. Exploration and research necessitates an in-depth review of known mineral deposits and prospects together with regional stratigraphic, structural and geophysical studies in order to develop an Integrated exploration model. The Millbridge Property's proximity to the pristine Long Lake zinc mine as well as the presence of base metal occurrences within the local area of the property enhance its' mineral potential.

It is felt that the MVT model of mineral deposition employed for the Grenville is not adequately expounded upon. This OPAP'92 project, an exploration of a known Pb/Zn area for application to the MVT model, is adequately overviewed as a very preliminary phase of exploration. Preliminary work has delineated potential fairways for mineralization; these require emphasizing. It is suggested that additional and intensive detailing be completed and application of a variety of geophysical methods, perhaps a thermal halo geochemical survey and deeper exploration of soil geochemistry be further employed to continue to explore this viable model of mineral deposition.

This property, referred to as the Millbridge Property, in Tudor Township, southeastern Ontario is a complex property posing many questions. The currently known typical MVT model of Pb/Zn deposits indicates that this property tends to exclude its' potentiality. Further work is required on this property to better understand and evaluate its' dynamics.
