Tom Cat : Canada



Tom Cat property is located 200 kilometres east-northeast of Vancouver and within the historic Aspen Grove copper camp. The property is comprised of eight contiguous mineral claims covering an area of 3,142 hectares.

The Aspen Grove area was recognized for its potential in developing economic mineral deposits since the late 1880’s when copper mineralization was first discovered in the area. Two of the earlier discoveries, the Tom Cat and the Bunker Hill, were made on the ground covered by the Property which now includes nine documented mineral prospects or showings in a localized three by two kilometre area or approximately only one-quarter of the entire Property.

Although the Property has a history of exploration, the only significant results reported prior to 2006 was a drill intersection of 45.7 metres of 0.32% copper in a 1965 Pyramid Mining drill hole on the Tom Cat showing. Exploration work by Bold Ventures in 2006 & 2007 resulted in the delineation of viable chargeability IP drill targets and copper soil anomalies associated with mineral showings. A drill hole on the Tom Cat showing confirmed the historic result in the intersection of 4.4 metres of 0.54% copper in a 40 metre section of noted mineralization. The entire 40 metres of noted mineralization was not sampled. The author took samples from the Bold Ventures Tom Cat mineralized drill intersection which assays verified the mineralization.

Geologically, the Property predominantly covers the central facies of Triassic volcanic and lesser sedimentary rocks of the Nicola Group. Late Triassic felsic intrusives intrude the Nicola rocks resulting in variable degrees of alteration in the volcanics and/or sediments which may intensify at or near mineral zones. Portions of the major Summers Creek/Kentucky Lake fault traverse the Property providing potential structural controls to mineral zones and/or reveal surface indications of potentially economic sub-surface mineralization. The mineral showings on the Property may actually be such surface mineral leakage indicators and exploration should be designed to explore for deep seated mineral zones.


The Tom Cat property is 2.0 kilometres west-northwest of the north end of Bluey Lake and 2.25 kilometers west-southwest of the south end of Kentucky Lake. This deposit is hosted in green laharic breccia or basaltic flow breccia near the contact with red laharic breccia of the Upper Triassic Nicola Group (Central belt, Bulletin 69). The unit strikes north-northwest and dips 60 degrees east. Massive basaltic flows outcrop to the northeast. Alteration of the breccia consists of some chloritization of olivine and pyroxene, and sericitization of feldspar. The laharic breccia is erratically mineralized with chalcocite, magnetite, bornite, chalcopyrite, native copper and hematite, as disseminations and fracture coatings. Trenching and diamond drilling has intersected this mineralization over a width of 30 meters and a depth of at least 45 meters. One drillhole analyzed 0.32 per cent copper over 45.7 meters (Minister of Mines Annual Report 1965, page 157, hole 1). Two chip samples assayed 2.4 and 1.6 per cent copper over 2.1 and 3.0 meters respectively (Minister of Mines Annual Report 1913, page 223). The occurrence was initially prospected and trenched by W. Murray between 1906 and 1913. Pyramid Mining Company Ltd. drilled 13 holes totaling 1042 meters in 1965.

The property is accessible from Merritt on Highway 5A to the west end of the Kentucky Lake Provincial Campsite junction, 22 kilometers south of Merritt. Take the secondary road for 1.8 kilometers south to the central northern line of the property. Many of the secondary roads give you access to most of the mineral showings on the property.

The region is situated within the dry belt of British Columbia with rainfall between 25 and 30 cm per year. 35 C could be the high temperature, an average of 25 C with winter temperatures reaching as low as -10 C and averaging 8 C. In a normal year it could snow December to April. A year round exploration program would be possible.

The Tom Cat Property is situated at the western edge of the Douglas Plateau, which is within the physiographic area designated as the Interior Plateau of British Columbia. Gentle to moderate slopes prevail with relief in the order of some 200 meters. Vegetation is grassland with pine groves and thickets of fir at higher elevations.
Local Resources and Infrastructure
Merritt or Kamloops, historic mining centers, could be a source of experienced and reliable exploration and mining personnel and a supply for most mining related equipment. Kamloops is serviced daily by commercial airline and is a hub for road and rail transportation. Vancouver, a port city on the southwest corner of, and the largest city in the Province of British Columbia, is four hours distant by road and less than one hour by air from Kamloops.

Potential Areas for Tailings Disposal and Plant Sites
There are adequate sites on and/or peripheral to the property for potential tailings storage areas, waste disposal areas and processing plant sites. The mine-mill operation would be subject to approved environmental impact studies and government regulation.



Regional Geological MapThe Tom Cat project area lies within the intermontane belt of Mesozoic rocks between Princeton and Merritt. This belt of rocks carries south into the United States and north into the Yukon Territory. The distinguishing and oldest rock group in this belt is the volcanic and sedimentary rocks of the Triassic Nicola group. Preto (Bulletin 69) has subdivided this group into the western, central, and eastern facies. The eastern facies is dominantly intermediate purple/gray/green flows, breccias, tuffs, lahar breccias, with minor sandstones and siltstones. The central facies is intermediate to basic flows, breccias and tuffs, with more dominant limestone, siltstone, argillite, and conglomerate. The western facies is acidic to intermediate flows, breccias and tuffs, with minor limestone. Intruding the Nicola volcanics are numerous stocks, sills, small plutons, batholiths and dikes of various ages and of a varied composition. The more sizeable intrusions are the Jurassic Pennask batholith, the lower Jurassic Allison Lake pluton, and the Cretaceous Summers Creek stocks. The intrusive rocks are acidic to basic in composition, however most are alkalic in nature. The most dominant rock descriptions are diorite, monzonite and granodiorite. The lower Cretaceous Kingsvale group of dominantly volcanic rocks unconformably overly the Nicola group and earlier intrusions. These rocks are intermediate to felsic flows, tuffs, ash flows and lahar breccias. The Summers Creek stocks intrude rocks of the Kingsvale group, Overlying all rocks are Tertiary basalts and andesites of the Princeton group and sedimentary rocks of the Coldwater beds.

Property Geology
The dominant rock types of the property are volcanic and sedimentary rocks of the central facies of the Triassic Nicola group, and stocks and small batholiths of Triassic diorites and monzonites. The eastern facies is present along the eastern property boundary. The central facies of the Nicola group has been subdivided into three basic units; flows, pyroclastics and sediments. The flows are most abundant and are described as purple/green amygdaloidal augite andesite with interbedded trachyandesite feldspar porphyry. The pyroclastic units are massive to finely bedded crystallithic andesite tuffs with interbedded siltstone and light gray/green dacite tuff. Graded bedding is locally identified, with occasional diagnostic lapilli sized fragments, common to explosive breccias and lahars. The sediments are dominantly interbedded greywacke, siltstone and minor conglomerate and massive beds of gray to light brown limestone. All Triassic rocks are hornfelsic in nature near the contact of intrusions. Some of the sedimentary horizons have developed slaty and/or schistose cleavages. The intrusive rocks on the property have been classified as alkalic late Triassic granodiorite and quartz diorite, and are located in one small batholith covering the southeastern area of the property. Late felsic and porphyritic dike swarms are found in all areas of the property, dominantly in the contact area of the batholith. The ages are unknown, however are probably related to late phase intrusive activity. Very late basic dikes are related to Tertiary vulcanism. These dikes are post-mineralization. Bluey and Kentucky Lakes form a strong lineal feature that probably is related to the northern projection of the Summers Creek fault. This lineament passes through the eastern boundary area of the claims. A splay fault trending northwest forms the western boundary of the granodiorite intrusion. Small local shears and fault zones were noted during the time of the property examination.

Deposit Types
The geological environment of the Tom Cat property is suited to host a number of deposit types. The principle targets are alkalic porphyry copper (gold/molybdenum) deposits similar in nature to the deposits of the Similco deposit near Princeton. There are many examples of replacement and skarn type of showings on the property.

Description of Mineral Deposits Under Investigation on the Tom Cat Property The geological setting and tectogenesis, the alteration and mineralization of the Pacific basin rim porphyry copper deposits description is typical of the Highland Valley Mine. The porphyry and skarn deposits of the Princeton, Merritt, Logan Lake areas are situated within a terrane that has a long history of strike-slip movements on numerous parallel faults. This mobile belt lies between the Coastal batholiths to the west and the edge of the North American Craton to the east. Within this mobile belt, small plutons have concentrated copper deposits during times of strong deformation, folding and strike –slip faulting. Locally, many deposits are located at fault intersections. Porphyry copper deposits are the products of large intrusion related hydrothermal systems, emplaced at shallow depths, and the subsequent cooling which resulted in the extensive evolution of secondary permeability (fractures) in both the pluton and the host rocks, promoting the circulation of hydrothermal fluids.

A review of plate tectonics related to porphyry copper evolution suggests that episodes of intrusion correspond to times of higher convergent rates, to times when the convergence style changed and most fundamentally to destructive plate margins. Different convergence styles, such as, oblique convergence, may prepare the crust to permit rapid access of magmas to shallow levels. The intrusion centers, to which the porphyry deposits arerelated, differ in many ways and There is no typical rock type or configuration. The Guichon Creek batholith for example, has 6 distinct zones, indicated by compositional and textural differences of each intrusion, The oldest and outer zone ranges from diorite to quartz diorite, while the younger, more centralized zone ranges from granodiorite to quartz monzonite. In summary, the 2010 exploration program direction is to create a surface geology map of the Dansey Property, outlining contact zones between plutons and wall rocks, and any small unmapped plutons on the property. Secondly, complete ground geophysical surveys to search for anomalies to diamond drill in the appropriate geological units.



The mineralization and alteration, noted on the Tom Cat property by present and previous geologists, are mainly related to the faulted structures and to the intrusive rocks on the claims. In total, nine old mineral prospects are reported on the property, seven having been found and examined and sampled.

1) Tom Cat Showing: Rock types examined included med grained granodiorite in contact with andesites of the Nicola Group. Mineralization observed is chalcopyrite, chalcocite, pyrite, magnetite and malachite disseminated in altered granodiorite. Alteration included epidote, chlorite, sericite, quartz and calcite. A chip sample (K-02) across a 2 meter face of the trench assayed 3.68% copper. 20 meters west of the trench, a well-mineralized pod (sample K-03) assayed 1.77% copper across 1.5 meters. Two old drill pads were located from drilling in the 1960s. One of these holes reports 0.32% copper over 45.7 meters of core length.

2) Bluey Showing: Chalcopyrite, chalcocite, pyrite, malachite and azurite are associated with small quartz veinlets hosted by altered andesite of the Nicola Group. Alteration includes epidote, chlorite, quartz and sericite, with considerable rusting from oxidized sulphide minerals. One chip sample (K-04) across a 4 meter length indicates 9189ppm copper, 1551ppm lead, 7973ppm zinc and 10.9ppm silver.

3) Bunker Hill Showing: Located in volcanic rocks, very near an intrusive contact. Brown carbonate alteration and quartz veining were observed in several pits and short trenches. Chalcopyrite, chalcocite, pyrite and malachite are found in altered zones. One chip sample K-05 across a 2 meter width yielded 3.73% copper.

4) Portland Showing: Mineralization was not observed in bedrock. A black mineral (chalcocite or magnetite?) was evidenced in samples from the dumps leading from the shaft. A sample (K-06) of this material yielded 1702ppmCu.

5) AR Showing: Two old trenches expose altered volcanic breccia and andesite/basalt flows of the Nicola Group. Chalcopyrite, pyrite and malachite are located as replacement pods and smears along fracture faces of altered volcanic rocks. Alteration includes epidote, carbonate, chlorite, minor quartz and sericite. A chip sample (K-01) over 1.5 meters length yielded 6962 ppm Cu.

6) AR 2 Showing: Located an old pit is a shear zone of altered Nicola Group volcanic rocks. Pyrite, chalcocite?, and malachite are found in shears. A chip sample (K-07) across 0.5 meters yielded 5347ppmCu. The showing area is associated with only weak soil geochemistry and no chargeability IP anomalies, and was not drilled in 2007.

7) Bloo Showing: Could not be located. Reports indicate chalcopyrite and malachite in altered diorite, with assays reporting up to .483% copper.

8) Boomerang Showing: Could not be located. Chalcopyrite, bornite and malachite are reported along fractures of altered diorite. Main alteration is chlorite. Mineralized samples are reported to range 0.18 – 14.7% copper with up to 4 g/t Au and 74g/t Ag.

9) AM Showing: Could not be located. Reported assays range up to 2% copper over 1.5 meters. Several other alteration and shear zones were observed in the area, near the contact of the volcanic Nicola Group and diorite/granodiorite intrusion.


A considerable amount of exploration work has been completed on the ground covered by the eight Tom Cat claims which cover a 3,142 hectare area of prospective geologically favorable ground for the location of potentially economic copper/gold porphyry related mineral zones hosted by intrusives, copper/gold skarn mineral zones hosted by calcareous sediments of the Nicola volcanics, or mineralized veins or shear zones hosted by intrusives or Nicola volcanics. The Tom Cat property, with the nine documented mineral prospects and/or mineral showings of variable types of mineralization, indicates the potential for the development of economic mineral zones. The more recent exploration results provided by the exploration work of Bold Ventures Inc. in 2006 and 2007 have considerably enhanced the prospect for this development. The 2006 IP survey has provided excellent targets for exploration and the limited drilling completed in 2007 has established the presence of extensive copper mineralization on the Property. The results of the exploration work has delineated specific areas for advanced exploration and indicated two areas of prospective porphyry-style mineralization which require expanded and detailed exploration. The Tom Cat property is of sufficient merit on which to warrant an exploration program as recommended herein.

A two-stage program is recommended as follow-up exploration to the historical results and the Bold Ventures Inc.results obtained from the exploration completed on the ground covered by the Tom Cat property. The work program would generally follow the recommendations as set out in a report by Kerr (2007) on the completion of a six-hole, 1,018.4 metre diamond drill program. Stage I would be focused on the northwest and the southwest anomalous areas and would be comprised of establishing east-west grid lines at 100 metre spacing to the west and north of the northwestern IP anomaly and to the west and south of the southwestern IP anomaly. The grid would be utilized as a control for a soil geochemical survey, and an IP survey. Stage II would be comprised of one or two deep diamond drill holes to explore the causative source of the IP anomalies which would also determine the economic mineral potential to the drilled depth. The analysis of the core, primarily for mineral type content, and alteration sequence, would also serve as a guide to the location of porphyry mineralization which the Tom Cat property has all the essential geological features.
