Vegetation on the property consists of spruce, pine, and balsam with some willow alder, poplar, and tamarak.
History
Lead-zinc-silver mineralization was first discovered in the area and subsequent claims staked in the late 1930s. In 1943, Cominco prospected the area. Datalaska Mines, between 1960 to 1963, conducted a program consisting of hand trenching and sampling on a mineral occurrence known as the Matt Berry Zone, located one kilometer north of the property.
Matt Berry Mines Ltd. ("Matt Berry") was formed in 1965 in order to develop the the Matt Berry Zone located adjacent to the property. Between 1966 and 1970, considerable work was carried out on the Matt Berry Zone including hand trenching, VLF electromagnetic ("EM") surveying, geochemical surveying, Turam EM surveying and diamond drilling. A total of 31 drill holes (2,728 meters) were drilled on the Matt Berry lead-zinc-silver zone (the "Matt Berry Zone"). In 1970, an additional 2 drill holes totaling 391 meters were completed under an agreement with Metallgesellschaft Canada Ltd. and Canadian Nickel Company Ltd.
In 1972 Nordev Resources optioned the claims and sold a 40% interest to New Joburke Exploration Ltd. In 1974, Cyprus Anvil Mining Corporation held an option on the property and conducted a gravity survey over a portion of the property.
All claims were allowed to lapse and in 1977, Sovereign Metal Corporation, the predecessor of Kobex Minerals Inc. restaked the ground and carried out a data review and estimated a resource of 588,000 tons grading 6.1% lead, 4.6% zinc and 3 ounces of silver per ton for the Matt Berry Zone. In 1978, the property was optioned to New Frontier (NPL), who conducted a pulse EM survey. The property subsequently reverted to Sovereign Metals Corporation who conducted a trenching program in 1979. Cominco optioned the property in 1980 and conducted a drill program of 5 widely spaced, diamond drill holes totaling 1,229 meters. The drill program failed to intersect any encouraging mineralization.
During 1981, Cominco conducted a program of geological mapping and soil geochemistry on the present property. Several coincident lead and zinc anomalies underlain by a quartz-augen schist unit were identified. Several copper anomalies, including one that is 400 by 600 meters in size, were also outlined. The copper anomalies were found to be located up-slope from the quartz-augen schist unit and to be underlain by sparsely exposed, metamorphosed mudstone and siltstone strata.
In 1987, Pulse Resources Ltd. carried out 43 line kilometers of ground magnetic surveys that covered newly discovered mineralization named the Money Zone. Geochemical soil sampling was completed on the same grid and in 1988 a program of induced polarization and detailed geochemistry was carried out over the Money Zone.
In 1991, Pulse Resources Ltd. ("Pulse") conducted a 4-hole diamond drill program totaling 303 meters to test a 450 meter strike-length of the "Money Zone". The Money Zone area is outlined by a 600 meter-long coincident lead-zinc soil geochemical anomaly with favorable stratigraphy, similar to that found at the Matt Berry Zone located one kilometer to the north. Moderate to strong IP chargeability features were also defined in the Money Zone area. Results from the Pulse drill program included 1 to 3 meter-long intercepts of semimassive to massive sulphides in 3 of the 4 holes with minor base metal values. One of the drill holes, PUL91-1, returned a 0.5 meter intercept of base metal mineralization that assayed 5.87% zinc and 1.82% lead. Pulse dropped their option in 1992.
Barytex carried out line cutting, geological mapping and prospecting between 1992 and 1995 on the property. In 1998, Barytex carried out an airborne geophysical survey which outlined conductive responses along strike from the Matt Berry Zone and downslope from the Money Zone.
Geological Setting
The property area is underlain by Devonian-Mississippian metasedimentary rocks in contact with Cretaceous quartz monzonite of the Mount Billings batholith. Extensive glacial till masks much of the underlying stratigraphy in the Francis Lake area. Regional faulting in the area is characterized by major east-west striking faults and less pronounced northeast trending faults.
The Barb property is underlain by Devonian/Mississippian phyllitic rocks that form the western limb of a north-northwest trending syncline. The phyllitic rocks form two conformable units: a dark green to black phyllitic unit overlying a lighter grey, fine-grained unit. Cherty tuffaceous beds occur within the dark phyllites and host thin-bedded, massive sulphides on the adjacent Matt Berry Zone. Phyllitic rocks on the property host an extensive quartz-sericite unit that is locally sulphide bearing and possibly volcanic in origin.
Deposit Type
Historically, the area including the adjacent Matt Berry Zone has been explored for shale-hosted Sedex massive sulphide deposits. Although felsic volcanic rocks had been noted previously in the area, their significance has only recently been recognized. During the 2000 field season, Fonseca, a geologist working for the YTG Mineral Resource Branch carried out fieldwork in order to refine the mineral deposit models applicable to the western part of the Selwyn Basin in the Frances Lake map area. This work led to a redefinition of the Matt Berry deposit model. Fonseca writes that "the copper-rich nature of the ore, volcanic textures in the ore contacts, and the presence of alkaline felsic metavolcanic rocks beneath the deposit suggests that the mineralization fits a mineral deposit model intermediate between Sedex and VMS end members."
Mineralization
The mineralization comprising the Money Zone consists of zinc and lead sulphides in pyritic layers hosted in an extensive quartz-sericite unit of possible volcanic origin. Semi-massive to massive sulphides have been intersected in 3 of 4 diamond drill holes and range in thickness from 1 to 3 meters. Sulphides include semi-massive pyrite, disseminated to banded sphalerite, galena, pyrrhotite and minor chalcopyrite and arsenopyrite. A 0.5 meter interval in one hole assayed 5.87% zinc and 1.82% lead.
Exploration
Geological Mapping In June, 1995, Barytex carried out geological mapping and prospecting on the property. The mapping was carried out along cut lines spaced 400 meters apart. The areas covered by the mapping are underlain mainly by dark grey phyllitic rocks that are generally thin bedded and in places are hornfelsed with a well-developed slaty cleavage. Quartz veins, both concordant and discordant, are common. A quartz augen schist unit about 150 meters thick, probably of volcanic origin, was mapped within phyllitic strata on the property. In general, bedding strikes southeast and dips northeast from 20 degrees to 50 degrees. Airborne Geophysical Survey
In September, 1998, a "Dighem" airborne geophysical survey was carried out over the Barb property. Dighem is a proprietary airborne geophysical system owned by Geoterrex Dighem, a division of CGG Canada Ltd. The survey was carried out by Geoterrex-Dighem of Mississauga, Ontario. The survey consisted of approximately 172 line-kilometers with flight lines flown in a direction of 60° at a line separation of 200 meters.
The purpose of the survey was to detect zones of conductive mineralization and to provide information that could be used to map the geology and structure of the survey area. This was accomplished by using a Dighem multi-coil, multi-frequency EM system, supplemented by a high sensitivity cesium magnetometer. The information from these sensors was processed to produce maps which display the magnetic and conductive properties of the survey area. A global positioning electronic navigation system ensured accurate positioning of the geophysical data with respect to the base maps. Visual flight path recovery techniques were used to confirm the location of the helicopter where visible topographic features could be identified on the ground.
Several anomalies in the surveyed area which are typical of bedrock conductors were defined as a result of the geophysical survey. A high priority EM anomaly located immediately to the west and parallel to the Money Zone, is coincident with an IP anomaly that has not been tested by drilling. The conductor is at least 600 meters in length.
The airborne geophysical survey results are considered to be reliable and follow-up with detailed surface geophysical surveys to define drill targets is warranted.
Geochemical Surveys
Three geochemical surveys have been conducted on the property and on surrounding areas. The survey results are summarized below:
- In 1981, Cominco collected 1,179 soil samples, 16 silt samples and 34 rock samples which were analyzed for copper, lead, zinc and silver. Results indicated several co-incident lead and zinc anomalies and widespread higher copper values upslope from the lead and zinc values. Anomalous levels were considered to be 70 ppm copper, 23 ppb lead and 100 ppm zinc. Geophysical surveys were recommended.
- In 1987, Strato Geological Engineering Ltd. (Strato) on behalf of Pulse Resources established a new grid on the property and surrounding area (100 metre line spacing and 25 metre sample spacing) to cover known mineralized areas. A total of 720 soil samples were analyzed for copper, lead, zinc, silver and arsenic. Anomalous values were defined as mean value plus 1 standard deviation and highly anomalous values as mean value plus 2 standard deviations.
- In 1988, Strato conducted a detailed survey in the area of the Money Zone by infill sampling between the 1987 lines. Two hundred and seventy seven (277) samples were collected and results supported the 1987 work. A number of anomalies for each element were defined. A general northwest trend to the anomalies is evident conforming to the trend of the Matt Berry mineralization and the geophysical anomalies.
Deep overburden in the area as indicated by the 10-20 meters encountered in the Money Zone drilling along with reported muskeg, swamps and heavy vegetation most probably hinders the exact definition of possible mineralization by geochemical means. The anomalous levels used by Cominco and Strato are different and likely reflect the larger sampled area covered by Cominco.
Drilling
No drilling has been carried out on the property by Barytex. Historical records include drill logs, assay results and sections developed from the diamond drill holes completed by Pulse.
In July, 1991, a 303 meter (4 holes) BQ diamond drill program by Pulse tested 450 meters of strike-length on the Money Zone. This area is underlain by a 600 meter-long, coincident lead-zinc soil geochemical anomaly, favorable stratigraphy and moderate to strong IP chargeability features. Results of the drill program included 1.0 to 3.0 meter-long intercepts of semi-massive to massive sulphides in 3 of the 4 holes drilled. A 0.5 meter intercept of base metal mineralization intersected in hole PUL 91-1, assayed 5.87% zinc and 1.82% lead. The mineralization is hosted within a quartz sericite schist unit that may have significant base metal potential.
Sampling and Analysis
The diamond drill program in 1991 was carried out by Pulse. The drill core was logged and mineralized sections split and sampled. Sample intervals ranged from 0.5 meters to 1.5 meters. Overall core recoveries ranged from 65% to 75%. However, recoveries from the mineralized section in hole no. PUL 91-3 ranged from 8% to 80% and averaged 39%. The low recoveries may have affected the accuracy of the results. The assaying was carried out by TSL Laboratories in Saskatoon, Saskatchewan. It is not known what quality control measures were carried out by the laboratory.
Security of Samples
Reports available to Barytex regarding historical work and more recent work do not describe measures taken to ensure the validity and integrity of samples.
Mineral Resource and Mineral Reserve Estimates
No mineral resource estimates have been carried out on the Money Zone.
Exploration and Development
Although the Company has not proposed a current exploration program on the Barb property, a future exploration program should include a ground geophysical survey program to detail selected airborne geophysical targets. These geophysical anomalies would then be tested by diamond drilling. One high priority target is located immediately to the west and parallel to the Money Zone. The Company is currently re-evaluating its strategy on this property.
