A technical report filed on SEDAR in March 2009 stated that in excess of 16.5 million tonnes of valuable surface sand and gravel has been identified on a portion of the Company’s 100% owned Kenville Gold Mine Crown Grant property. The Technical Report was completed using computer modeling with data obtained from a total of 79 sites that included trenches and drill holes from the 2007 and 2008 exploration programs. The report based limited reliance on the information from the staff and records of Anglo Swiss, the drill data from MPH Consulting and the core logging by Greg Thomson, P.Geo. and Kodiak Measurement Services Inc. which also preformed engineering volume calculations with computer models of the drill and test hole data.
The computer models utilized by Munroe Geological Services Ltd. plotted 79 sites on the study area with the known topographic elevations and contours. An average overburden depth is 6.5 metres over an averaged area of 1,059,255 square metres. The Kodiak model (Kodiak Measurement Services Inc.) resulted in the calculation of a measured resource of 6,885,159 bank cubic metres. Using the accepted bulk density average of 2.4 tonnes per cubic metre, the study area tonnage would be 16,524,380 tonnes of measured resource material available for processing into aggregate products. The report included personal inspections and measurements to obtain the majority of the data for the Technical Report; limited information was obtained from the 2007 and 2008 exploration programs. The sand and gravel target areas are situated on top of and around several old and current gold mine areas.Metal values in proximity to the contact may be expected. Mineralization of the potential construction sand and gravel materials located on the Kenville property are not a focus of this report. However the location of these identified materials are shown on Map 3, located in close proximity and literally on top of existing vein structures and old adits such as the Jack Pot adit and next to the old Venango Mine workings. There is the potential for auriferous materials to be located in the aggregate fines during planned sand and gravel processing. As a result the following three assay sheets have been included to indicate the precious metal contents that can be found in the hard rock below the till/gravel cover. The samples were from the area of the old Jackpot mine and test hole RM-08-02 shown in satellite photo Test Pits 1-12 and Test Pits 18-22. The two samples from the Jack Pot adit were taken from mineralized rock found at the adit face. No defined vein structure was noted at the time. The test hole samples were obtained from the excavator bucket as it hit the bedrock surface within 3 metres of the top of the trenches. No further determinations could be made with respect to the size, type or orientations of the mineralized vein materials. Two assays were obtained from the Jackpot adit. They resulted in gold values of 4.51 g/t and 0.03 g/t with the rock being poorly mineralized.The test trench samples were also poorly mineralized but returned values of 0.04 g/t and RM‑08-02 and 0.07 g/t at RM-08-20. The 2007 drilling program was carried out over a small portion of a large surveyed grid area located on the west side of the Kenville property.The original grid area was established in 1995 as part of exploration programs carried out by Teck Exploration Ltd. (“Teck”). Teck originally investigated the potential for a porphyry copper deposit, as was indicated by drill logs for two drill holes from a 1945 drill program on the property. Teck carried out diamond drilling programs in 1995 and 1996 with the drilling of 5-holes in 1995 and 7-holes in 1996. Although encouraging results were obtained in the majority of the drill holes, the lack of adequate access prevented a more thorough investigation of the more promising target areas on the property at that time. Since the Teck exploration work, Anglo Swiss expanded the grid area on the western side of the property in 2007 and 2008. Geochemical soil surveys have been carried out in various stages, resulting in the recognition of strong, well-defined copper + silver + molybdenum anomalies, covering a distance of at least 700 metres. New road access has been established through the grid area, thus allowing more advantageous locations for drill testing of prospective mineral zones. During September of 2007, an Induced Polarization survey was carried out on the grid area by Insight Geophysics and MPH Consulting of Ontario. A total of 18.7 line-km of gradient and 5.9 line-km of high resolution (25 metres data point spacing) Insight Section resistivity and chargeability data were collected, covering approximately 20% of the property. The survey was carried out on 50-meter line spacings, thus providing excellent detail for interpretation of survey data.
These data have been interpreted, in the context of the deposit model for the property, to indicate possible alteration zones associated with porphyry style copper (Cu), molybdenum (Mo), gold (Au) and silver (Ag) mineralization. Moderately high, and roughly N-S trending, chargeability anomalies are coincident with historical Teck copper and molybdenum soil geochemical anomalies. A Phase One diamond-drilling program totaling 1365 metres (4478 feet) was carried out by Full Force Drilling for Anglo Swiss in October 2007. The drilling consisted of 5-drill holes, drilled from 3 set-up locations. Drill holes AK07-01 and AK07-02 were drilled from the first set-up location (Line 2500N, 140W), while drill hole AK07-03 was also drilled on Line 2500N at station 325 W. Drill holes AK07-04 and AK07-05 were drilled from a third common location on Line 2600N at station 225W. The following table summarizes some of the significant visual results from the 2007 drill program:
It should be emphasized that the area tested by the 2007 Kenville diamond drill only covered 100 metres of north-south distance of the 1000 metre established grid length, with the entire grid area representing about 20% of the entire Kenville property. Based on the results obtained from the 2007 Phase One drill program, within a small area of the property, the Company continued exploration of the Kenville property. Based on the 2007 drill holes, in combination with the results obtained from several of the 1995/1996 Teck drill holes, a copper-gold porphyry deposit model was thought possible but more work was required to define that theory. Well-defined coincident geochemical and Induced Polarization anomalies, throughout the extent of the grid area are also supportive of a hypothetical mineralized porphyry body. In addition to the porphyry model, Anglo Swiss explored the newly identified Eagle vein as found in drill holes AK07-04 and AK07-05. With these two intersections, the vein is now known to extend for at least 150 metres or about 500 feet from the vein intersections in Teck drill holes TK95-04 and TK95-05. Visible gold was seen in both of the Teck drill hole Eagle vein intercepts, with the highest value of 82.15 grams per tonne gold (2.4 oz/Ton Au) and 34.1 grams per tonne silver (1 oz/Ton Ag) returned in TK95-05 across 0.26 metres or 0.85 feet. The Eagle vein is expected to continue beyond its known 150 metres strike length and is open to depth. The south west quadrant of the Kenville property contains a type of mineralization typical of an alkalic copper-gold porphyry deposit type, in which concentrations of pyrite, chalcopyrite, bornite and magnetite occur within large bodies of porphyritic diorites. British Columbia alkalic porphyry deposits range from less than 10 million to greater than 500 million tonnes and contain from 0.2 to 1.5 % copper, 0.2 to 0.6 grams per tonne gold and greater than 2 grams per tonne silver. Molybdenum contents are generally negligible. Known British Columbia alkalic porphyry deposits include the New Afton deposit, near Kamloops, BC (66 million tones grading 1.02% Cu, 0.77 g/t Au and 2.59 g/t Ag), Mount Polley, near Williams Lake, BC (40 million tonnes grading 0.448% Cu and 0.318 g/t Au) and Galore Creek in Northern BC. (540 million tonnes grading 0.557% Cu and 0.303 g/t Au). The writer has worked in the Mount Polley area and similar dioritic host rocks have been seen on the Kenville property. More exploration is required to progress further on the theoretical model for any type or size of porphyry on the property.
The prospectors had to resort to random sluicing techniques to cut gullies in the till cover to expose bedrock. Numerous cuts were made since the early 1800’s and some of the surface exposures for the veins were located. Once a general north south strike trend was determined for some of the main veins, prospecting efforts were continued both east and west. Six main veins were eventually located in a semi parallel format with an average dip of 45 degrees to the east. They were noted as:
The veins were found to be quartz hosted with varied degrees of gold, silver, pyrite, chalcopyrite, sphalerite and galena. It is important to note that the prospectors of the day were general placer miners with little experience or understanding of lode quartz vein systems. In general terms the current mapping program has determined that the main auriferous vein system appears to have a feed source for the hydrothermal solutions at depth to the east. Most of the enrichment of the quartz veins has occurred in an exothermic environment but some veins display mesothermal mineral associations that will be discussed in the mineralization section. The main veins all strike 10 to 30 degrees west of north and show a general dip of 45 degrees to the north east. They can range from 0.03 to 1.8 metres (one inch to 6 feet) in width. On a localized basis the structure can change rapidly where the dip will alter from 20 to 75 degrees. The veins are located in weak fault zones in the host diorite. To further complicate the model, a series of in-filled horizontal tension cracks have been located at depth. The most pronounced horizontal system is the historical #1 Flat Vein located in the 1940’s at the south end of the 257 Level. It has an unknown maximum width but displays thicknesses of at least 1.5 metres (5 feet) with a core of at least 61 by 61 metres (200 by 200 feet). The flat vein is open to the north south and west. The western flank has been offset by a 16.5 metres (55 foot) vertical displacement upward at the main Hardscrabble vein intersection on the 212 drift of the 257 Level. West of the offset is the area known as the Jewellery Box stope. The stope displays a significant enrichment in metals such as galena, copper silver and gold in the quartz host while maintaining the same orientation and character of the #1 flat vein to the east of the offsetting fault. To the east of the #1 Flat vein the fault systems become much more complex with assorted intersections of the Yule vein (main sub vein parallel to and east of the Poorman vein) and what appears to be a second downward deflection of the main horizontal tension crack. This has been referred to as the Upper Stopes off the south Yule drift. East of this structural intersection is yet another flat tension crack infill that has been sub drifted for at least 32 metres (105 feet). This is referred to in the mapping as the 1281 sub-drift (see Appendix I in the NI_43-101 report for detailed mapping of the sub-drift ). This sub-drift has produced a wide range of assay values from trace limits to a clearly anomalous 2,696.00 g/t Au (sample SY-L-25) in a section where the next largest value was 43.55 g/t Au. The treatment of this and other effects of a nugget like gold environment are discussed in the Resources section. Much like the Jewellery Box stope to the west this sub-drift requires further examination for understanding the emplacement systems that flooded the flat tension veins after the main 45 degree veins were in place. It was also noted that visual differences were obvious in the flat vein systems that had been stoped. The colour, texture, inclusions and flares of original host rock were different from face to face and vein to vein. The geochemical work shows that the 1281 sub-drift, Upper stopes along the south Yule and the north and south halves of the #1 Flat Vein are indeed different in chemistry. This suggests that while they are all in proximity to each other, they had different feed stocks. The source(s) of the feed stocks are still in question but may be one or more of the minor veins running parallel to and between the 6 main known veins. Appendix J of the NI 43-101 report details the flat vein area and shows the placement of the “New Vein” translation that could be the feed stock for the tension cracks. This “New Vein” was located in the 257 Level 180 degree cross cut midway between the Hardup and 215 veins from the original mine mapping. The new cross sectional analysis in Appendix F of the NI-43-101 report shows the development of the random vein intersections into a concise new structure. It is also important to note that the analysis has shown the potential presence of at least 8 additional vein traces on the 257 cross cut. These traces are seen in some cases as thin stringers but have stronger widths in drill intersections away from the cross cut walls. Each of these vein traces will be examined in the pending underground diamond drill program. The New Vein is intersected in the flat 1946 DDH 94 drilled from the end of the refuge stope drift. The vein is muted in the series of parallel quartz stringers south of the known #1 flat vein between 23.5 and 29.4 metres (77 and 96.3 feet). This complex structural picture and emplacement of auriferous materials within the hydrothermal solutions over a series of actions indicates that the deposit type is a fault hosted body with primary enrichment in the vein fills. However as can be seen some of the Ministry of Energy Mines & Petroleum Resources historical production assay sheets in Appendix C of the NI-43-101 report. There are also places of hanging wall and footwall gold enrichment not reflected in these production totals. This aspect will have to be more fully examined in later reports. The source of the enriched vein fluids appear to have several sources at depth and may assist in explaining the distinct geochemical variations found in both the vertical and horizontal veins. While the orientation of the three of the main known veins east of Eagle Creek appear to be from a deep eastern source, the cross sections in Appendix F of the NI_43-101 report show that the Hardscrabble, Hardup and Poorman veins may have a source roughly 100 metres (328 feet) below the 257 Level of the main Mine area. The sections indicate not one but three areas of exploration interest below the main Mine to the east of Eagle Creek. They are noted as the West, Middle and East Deep Zones. Much of the dyke fills appear to come from the West Deeps. This may show a totally different magmatic source rock since the dyke fills contain totally different materials. To further understand this “Deeps” source theory, the west side of Eagle Creek was examined with additional cross sectional analysis of known veins and faults. Under the Venango vein system the assorted sub parallel veins were assembled into a pre-shear status and another deep target was also identified. This area of exploration was called the Venango Deep Zone. However, in this situation the faults and veins all seem to have a single source again at a 100 metres (328 foot) depth below the 257 Level. The Deeps areas under section line N3 are roughly in line with the Venango focus point. The Kodiak Measurement Services Inc. map in Appendix I of the NI-43-101 report show one of the current Anglo Swiss Drill holes (AK08-19) in the area of the Venango Mine, west of Eagle Creek. This is roughly the center of the Venango Deep Zone. The rough trace of Eagle Creek is actually along the series of underground survey points from KP 1 to KP 50. Between KP 8 and KP 9 is survey point 785. This is roughly just east of the center of the West Deep zone. Along the N3 section trace are the Middle and East Deeps. South of, and parallel to, the N3 line is the S6 section line. Roughly right under the Jewellery box area is the location of that Middle Deeps area. There is insufficient drill data currently available to extrapolate further into this theory. However, future drilling will investigate these focus points at depth. The following six cross sections depict the orientations and structural elements of the N3, S6 and Venango areas described above. Larger versions of the same sections are found in Appendix F of the NI-43-101 report for ease of viewing. The cross sections were developed by re-drafting old historical (1945 era) cross sections showing the interpreted vein, fault and structural intersections developed from the old drilling programs. The sections were then broken into vein and dyke translation elements due to movement along the shear planes. When re-constructed the pattern of block movement was identified and each block section could be moved back to its place in a pre-shear status. The cooling process of the granodiorite within the regional syncline would have most likely been responsible for the periodicity and replication of the main north south joint structures that now host the 6 main historical veins. Additional joint fill veins may exist in the area but no data currently exists to support such a theory. As further movement and cooling events occurred hydrothermal and magmatic escapes of varied mineralogy and volume would have occurred from depth to infill the open joint planes. As the joints were filled, block sections developed. Primary and secondary order infill events would have occurred. The possible sources of the infill fluids are the theoretical targets of the deep drilling as developed by the block model shift analysis in the cross sections. Another out of place assay result was found at a location on the main Hardscrabble vein under the Eagle Creek trace. At survey point 457 (KP2) two assays were done along a roughly north south striking quartz vein with a dip of 55 degrees to the east. MS 33 and 34 returned values of 7.950% Cu with 35.9 g/t Ag and 3.937% Cu with 33.3 g/t Ag respectively. These results are of interest as old diamond drilling to the east indicates pyrite, chalcopyrite and bornite roughly 38.1 metres (125 feet) east of this location (DDH 1 and 4). More work will have to be done to explore this area and provide comments on the results. |
