LUCKY MIKE
Copper Tungsten skarn
On the Lucky Mike property, polymetallic skarn mineralization is associated with altered sections of Upper Triassic Nicola Group rocks. Calcareous volcanics, tuffs and limestone of this unit have been in part, converted to garnet-epidote- calcite skarn with associated copper, tungsten, silver and minor gold and zinc mineralization.
Recent drilling has indicated that tungsten mineralization is widespread in the garnet skarn while copper-zinc- gold-silver values tend to be restricted to late crosscutting structures.
The main skarn unit is over 110 metres long with a northeast strike. It occurs at the contact between epidotized andesitic breccias and intermediate to felsic crystal-lithic tuffs within a lens of limy volcanic rocks, lithic tuffs and limestone.
The skarn is bimodal in mineralogy, consisting of interfingering garnet skarn (andradite garnet, magnetite, epidote, hornblende, chlorite and calcite) and carbonate skarn (coarse calcite, epidote, hornblende, chlorite, minor magnetite or hematite) possibly reflecting original compositional variation (protolith-coarse, highly carbonated lithic tuffs(?). Numerous late, fairly wide, east dipping (30-50 degrees) fracture zones cut the skarn with local displacements. A major fault zone is evident in the hangingwall lithic tuffs.
Tungsten mineralization is confined to the bimodal skarn with fine to coarse disseminated scheelite.
COPPER STAINED OUTCROP
ON THE LUCKY MIKE
A drill hole intersection across 14.1 metres of skarn mineralization assayed 0.152 per cent tungsten.
Copper mineralization with silver and local zinc values appears to be structurally controlled and located along shallow east dipping fault zones within the skarn and in the footwall epidotized volcanics.
The structures are late (post-skarn). They are wider in the skarn than in the volcanics but yield lower copper and silver values than in the volcanics below. Sulphides consist of chalcopyrite, pyrrhotite and pyrite. Galena and sphalerite are also reported.
A diamond-drill hole intersection across 3.6 metres assayed 0.18 per cent copper and 38.39 grams per tonne silver.
DRILL CORE STORED ON
THE LUCKY MIKE PROPERTY
Tungsten values occur with the copper and silver where the structures cut through the skarn. Tungsten mineralization appears to be early (prograde(?) while copper, silver, zinc and gold mineralization is late (retrograde(?) associated with fracturing.
COPPER STAINED OUTCROPS

ZONE 3
Ag - Zn - Pb - Cu
MINERALISED TRENCHES ON THE ZONE 3 PROPERTY
The ZONE 3 claim area is underlain by intermediate volcaniclastic and flow rocks of the Upper Triassic Nicola Group.
A strongly brecciated shear zone within the Nicola Group andesite strikes 045 degrees, dips steeply to the northwest and is continuous over a strike length of at least 2000 metres.
This structure hosts three main zones of base metal mineralization.
Zone 1 consists of trenches and open cuts along the shear within andesitic tuffs. The shear varies in width from 3 to 8 metres and contains quartz stringers The veins are fractured and in places brecciated. The fractures are mineralized with sphalerite and galena.
MASSIVE SPHALERITE - GALENA
(ZONE 3)
Zone 2 is located approximately 650 metres along strike from Zone 3 In this area, several trenches expose brecciated andesitic tuffs mineralized with quartz, sphalerite, pyrite, chalcopyrite and galena.
Combined average assay results from diamond drilling were 0.157 per cent lead, 4.10 per cent zinc, 2.4 grams per tonne silver and 0.17 percent copper over 3.25 metres.
Zone 2 inferred reserves are 45,359 to 54,431 tonnes of similar grade.
This was based on a width of 8m and a length of only 50m
COMPILATION MAP
In Zone 3, galena, sphalerite, chalcopyrite, pyrite and pyrrhotite occur in a brecciated zone within a quartz-calcite matrix. The hangingwall consists of bleached and pyritic andesite which grades into numerous quartz and calcite veins mineralised with massive sphalerite and galena.
The footwall consists of highly silicified andesite containing quartz and calcite veins.
The mineralized and brecciated zone varies in width of up to 6.5 metres.
Zone 3 has been tested by diamond drilling and underground development to a depth of 50 metres over a length of 165 metres.
ZONE 3 ADIT
Unclassified reserves at the No. 3 zone are 258,523 tonnes averaging 1.69 per cent lead, 4.8 per cent zinc, 0.18 per cent copper and 12.34 grams per tonne silver. The true tonnage and grade was difficult to determine due to very poor drill core recovery along the shear. The grade is based on drill core and adit sampling (Elwell, 1971).
A much higher tonnage and grade could easily be expected.
The claims are located within an area recently clear cut logged due to an infestation of the mountain pine beetle. New roads have been built that have exposed new areas for exploration.

The historic price ratio of silver to gold shows that about 10 ounces of silver would buy one ounce of gold, a 10:1 ratio. Recently, the ratio is about a 50:1 ratio (with silver at $20/oz., and gold at $1000/oz.) As the silver to gold ratio returns to historic values, from 50:1 to 10:1, you may make over 5 times more money investing in silver, than gold!
SILVER RIDGE
HIGH GRADE - SILVER - LEAD - ZINC PLUS GOLD
Numerous mineral showings are aligned in a north-south direction for 3 Km. These high grade base metal showings were covered by Crown Grants which are now reverted. They comprised the Edinburgh, Elizabeth,Scotia, Annie, Agnes, Heronback and Salmon.
The property area is underlain by a steeply dipping package of rusty weathering, thinly bedded, black, metamorphosed argillite of the Lower Cambrian and younger Lardeau Group, intruded by an Early and/or mid-Cretaceous biotite granite intrusion.
The argillites have been extensively hydrothermally altered resulting in a considerable deposition of manganese.
Quartz and quartz-carbonate zones from 3 to 4 metres wide occur in a north striking, vertical shear zone in argillite. Up to 6 metres of manganese alteration occurs on either side of the shear zone along with seams of manganite. Mineralization in the quartz- carbonate and quartz consists of seams and veins of high grade argentiferous galena with sphalerite.
At the Agnes occurrence, an adit has been driven for 24 metres along the structure. In 1987, a sample of massive galena in a surface showing yielded 31.3 per cent lead, 13.1 per cent zinc and 363.3 gpt or 12.8 oz/t silver.
At the Annie occurrence, an adit has been driven 45 metres along the shear and a sample assayed 2742 grams per tonne or 96 oz/t silver and 72 per cent lead.
On the Scotia claims, a tunnel was driven 48 metres to intersect the zone at depth, assays have yielded 192 opt silver and 80 per cent lead.
At the Heronback occurrence, a good surface showing of mineralisation analyzed 2742 grams per tonne silver and 72 per cent lead.
Recent sampling has produced grades of...
3.03 oz/t silver, 12.32 % lead and 4.62 % zinc over 2 m
10.21 oz/t Ag, 21.90 % Pb and 13.76 % Zn over 0.5 m
PORTAL OF THE AGNES ADIT - SILVER RIDGE
(MINERALISED ZONE IS VISIBLE JUST INSIDE THE PORTAL)
The mineralisation occurs in several prospects in a north-south direction for about a 3000 m strike length.
It consists of a zone that assays up to 320 oz/ton silver, 80% lead and up to 17 grams per ton gold.
Results have been reported with grades up to 1,207 opt silver and 17 grams per ton gold. Lead ranges up to 80% with reports of zinc grading to over 20%
A VLF- EM survey revealed three main conductive zones.
Plus several one-line conductors.
A very strong VLF- EM anomaly correlates with the mineralisation. The size is a minimum 1,000 m east-west by 400 m north-south thus indicating an east-west strike. It is open to the west.
The main mineralised shear has a north-south strike. This indicates a new undiscovered cross cutting target for further exploration.

COLOSSUS COPPER PROPERTY
INTRODUCTION
The Colossus Copper property is located about 200 km northwest of Vancouver, B.C. on the Frederick Arm, a fjord on the Pacific Ocean's west coastline. The Frederick arm is situated about 50 km. northeast of Campbell River, B.C. The area lies at the northeastern end of the Vancouver Island Ranges.
High Grade copper showings were explored by three adits early in this century.
Studies to date have estimated that the zones in the area of the main workings contain about 200,000 to 250,000 tons of material grading between 1.5% and 3.5% copper and about - 0.75% Mos2. More recent sampling tends to confirm these estimations.
However a number of drill holes were reported to intersect further mineralisation, however these many intercepts are not included in the above figures. Significant values of up to 3 oz/t silver and 1% cobalt equivalent have also been identified within heavy sulphide zones.
COLOSSUS COPPER
GENERAL LOCATION AND CLAIM MAP
PROPERTY
The property is comprised of the following reverted crown granted claims ~ COLOSSUS (L.256), LAGOON, PORTAGE (L.259), CHAMPNESS (L.260), BLUE BELL (L.258), ESTERO BASIN, RIO TINTO (L.257)
These RCG's are covered by thirty MTO staked mineral cells. The claim encompasses an area of about 1,479 acres. The claims are accessed via logging roads from Frederick Arm off of the west coast of the mainland of BC.
GENERAL GEOLOGY
The property area is underlain by granodiorite of the Jurassic to Cretaceous Coast Plutonic Complex.
Fault and / or joint planes within the granodiorite have been highly silicified. These siliceous units contain high grade copper with molybdenite, silver, gold and cobalt mineralisation. The granodiorite has been faulted and intruded by dykes of intermediate to mafic composition.
The mafic dikes are fine-grained, dark green in color, often serpentinized, and probably dioritic in composition. They occupy north to northeast trending fractures and vary from a few centimetres to 3 metres in width. Quartz veins, often containing heavy sulphide mineralisation, also occupy east to northeast fractures in the area of the main workings.
MINERALISATION
Sampling has confirmed the presence of significant grades of
both copper and molybdenum. Previous grade estimates from the two zones blocked out by the underground development , have ranged from 3.5% to 1.5% copper and about 0.075% Mos2
Previous estimates for these blocks are in the range of 200,00 to 250,000 tons . No further modern attempts have been made to confirm these estimates or to expand the known mineralised zones.
Six representative samples taken from an exposed 12 metre x 15 metre mineralised zone averaged 2.65% copper and 0.25% molybdenum.
A further ten representative samples from another separate zone, 8 metres wide and 46 metres long gave average values of 1.41% copper and 0.94% molybdenite.
A grab sample of chalcopyrite with pyrite and sphalerite, assayed 28.10 per cent copper, 0.003 per cent molybdenum 0.056 gram per tonne gold, 105.2 grams per tonne silver and 0.959 per cent cobalt.
Soil and VLF-EM surveys have outlined further anomalies several hundred meters south of the known mineral zones. The signature of these anomalies strongly indicates that they are caused by a body of mineralisation similar to that found in the underground workings.
This anomaly is currently defined over 700 meters in length and open at either end. It is also believed that this anomaly is untested by drilling.
Airborne magnetic data also indicates the presence of several bodies south of the known mineralisation, which may represent diorite dykes. Diorite dykes are known to be spatially related to the underground mineralized zones.
RECOMMENDATIONS
It is recommended that the No 3 (lower) portal be opened and detailed geological mapping be carried out in order to target programs to delineate extensions of the known mineralisation.
It is recommended that an induced polarization survey be conducted over the linear anomaly in order to delineate areas of sulphide concentration for further drill testing.
It is also recommended that a reconnaissance soil and VLF-EM survey be carried out over the southern portion of the property. Detailed prospecting and sampling should be conducted in new areas of the property that are accessed by more recent logging operations.
A regional silt sampling and prospecting program would also be useful in assessing the area for a Porphyry Cu +/- Mo +/- Au
type of deposit. The drainage's in the claim area are known to be anomalous in copper, molybdenum and uranium.
DISCUSSION
Copper and molybdenum mineralisation occurs disseminated within the Granodiorite as well as in high grade massive sulphide zones. The past exploration has only been concentrated in small areas of the property near the main workings.
Further modern exploration for a porphyry type of copper moly deposit is definitely warranted. As well as further defining the high grade massive sulphide mineral zones.

GRANITE QUARRY FOR SALE
The Beaverdell Granite quarry is located 14 kilometres south of Beaverdell BC, adjacent to Highway 33. The hostrock of the Beaverdell Granite quarry is a granitic stock centred near this area. The stock has been dated at 49.4 +/- 0.7 Ma (Eocene)
The quarry trends northeast from Highway 33. It follows a 40-metre wide band of lightly jointed porphyritic granite for approximately 130 metres. The stone at the Beaverdell Granite quarry consists of pink, coarse grained (greater than 5 millimetres) porphyritic granite with phenocrysts of pink orthoclase feldspar up to 3.5 by 6 centimetres. Other minerals include plagioclase, quartz, biotite and minor hornblende.
The average modal composition of the quarriable (QR or Cascade Coral) unit is 15 per cent quartz, 55 per cent orthoclase, 20 per cent plagioclase and 10 per cent biotite and hornblende.
The quarry measures approximately 40 metres long by about 12 metres high at its face with large potential reserves extending north of the site.
The quarry was operated from the 1960s up to about 1987 by Canroc International Corporation. The company shipped the stone to its processing plant in Delta to produce monument stone, flooring tile and facing stone for interior and exterior uses. From 1965 to 1967, Continental Marble & Granite Ltd. produced crushed stone for artificial stone. From 1971 to 1972, the company produced building stone.
The stone was marketed under the trade name 'Cascade Coral'. To date, the quarry has produced approximately 90 tonnes of blocks for polished slabs and tiles. Also crushed and sized fragments for terrazzo, and precast concrete slab products were produced.

INDUSTRIAL TALC DEPOSIT
The North Talc, South Talc and Talc Lake deposits outcrops atop a ridge west of the Fraser River, 19.5 kilometres south- southwest of Lytton BC.
NORTH TALC ZONE
Significant talc occurrences were first reported in this area in the early 1950s by Geological Survey of Canada geologists. The area is underlain by phyllite, schist and foliated greenstone of the Permian(?) to Lower Cretaceous Bridge River Complex (Group) and by phyllite, schist and local conglomerate of the Upper Jurassic to Lower Cretaceous Relay Mountain Group.
Pods of serpentinized ultramafics of the Bridge River Complex occur in fault and normal contact with both units. Since 1992, a systematic program was completed on the North Talc deposit that has included geological surveys, bulldozer stripping, trenching and drilling.
The Talc Lake deposit consists of a lens of talc on the north side of the lake, which has been exposed over a length of 800 metres and a width of 50 to 150 metres. The talc lens is covered by 1 to 2 metres overburden but has been recently exposed by new logging roadcuts.
TALC LAKE ZONE
The talc is pale green to white with a creamy buff weathered surface.
In 1993, a 120-tonne composite sample was extracted and then in 1994 shipped to Finnminerals in Finland for pilot tests. Tests included were beneficiation from grinding, flotation, and micro-ionizing. Tests were also conducted on the chemical and physical properties of the talc, particle size distribution and paper-grade rheology tests.
The final product produced included talc filler and extender with an average particle size 10 microns and brightness of 80 to 83 per cent (ISO), and a pitch control with an average particle size of 2 microns and a brightness of 83 to 85 per cent (ISO). A coating-grade, slurry talc pigment was also produced meeting rheological specification of light weight coated (LWC) papers.
These tests were followed-up by LWC paper trial runs where several different weights of coated-grade papers were produced using the talc slurry.
The North Talc deposit is estimated to contain 13,000,000 tonnes and is 2.5 kilometres northwest of the Talc Lake deposit containing an estimated 5,231,600 tonnes.
The South Talc Deposit contains further drill indicated reserves of 11,947,456 tonnes. Geological inferred reserves are 1,387,650 tonnes for a total reserve estimation For The South Talc Deposit area of 13,335,106 tonnes.
Total Talc reserves in all three zones is
Thirty Eight Million Two Hundred Eighty Two Thousand Five Hundred and Sixty Two. (38,282,562) Tonnes.
