Vowell/Vermont Creek, British Columbia
Lead, Zinc, Silver, Gold
The property comprises 16,044 ha (39,645 acres) located approximately 35 km south of Golden. Previous programs on the property have been undertaken to evaluate potential for Sedimentary Exhalative (SEDEX), Replacement (manto) and precious metal-enriched base metal veins. The property has been the focus of programs to evaluate precious metal-enriched vein and/or replacement (manto) type mineralization, resulting in identification of anomalous silver plus lead plus zinc mineralization along both Crystalline and Vermont creeks. In addition, a proposed gold (plus arsenic plus zinc) mineralized halo was interpreted on the north side of Vermont Creek, based on anomalous results returned from soil, rock and drillcore sampling in 2003 and 2004. Management has emphasized evaluation of precious metal-enriched base metal veins, previously mined at the former Ruth-Vermont mine and for which remaining reserves (not compliant with 43-101 criteria) have been reported. Such vein-type mineralization has been the basis for exploration programs, including diamond drilling, undertaken by the Company between 1996 and 2004.
In an attempt to test the projected trend of the Ruth Vermont Vein System, a Fugro Airborne survey was completed on the property in 2005, resulting in identification of two prominent geophysical anomalies on the northeast side of Vowell Creek. A total of 8 drill holes, comprising approximately 1,224 metres, were completed to test the two geophysical anomalies, resulting in identification of two graphite-bearing horizons up to a maximum of 19.4 m thick. The Kaigyn Trend is approximately 1.2 km in length, truncated at each end by the survey boundaries, and the Mikayla Trend is at least 6.5 km in length. The two trends appear very similar on the basis of drill core recovered and may represent a fold or fault repeat of a single graphitic horizon. Based on visual evaluation of drill core recovered from the drill program, initial analytical results were surprisingly low. Work to evaluate the graphitic trends is ongoing at this time.
There are a number of MINFILE occurrences which lie along a distinct trend oriented northwest -southeast, which include (from south to north): VAD (082KNE031), Crystal Creek (082KNE011), Ruth Vermont (082KNE009), Syenite Bluff (082KNE037), Monitor / Southern Cross (082KNWE193), Malachite (082KNW182) and Diamond / No One (082N 010). Farther northeast, this trend can be extended to include the Flying Dutchman (082N 006), Bobbie Burns (082N 008) and Crown Point (082N 009) MINFILE occurrences. These documented mineral occurrences can generally be described as being comprised of moderate to high grade gold and silver with or without associated base metals (based largely upon grab samples documented in MINFILE). Furthermore, associated mineral types described include sphalerite and galena with ubiquitous pyrite, together with arsenopyrite, chalcopyrite, boulangerite, tetrahedrite, freibergite, scheelite and stibnite. Generally, this mineral association would be consistent with a vein-dominated mineral system, with local manto-type replacement deposits potentially occurring in association with carbonate-rich sequences within the siliciclastic-dominated Proterozoic Horsethief Creek Group grit succession.
Finally, the MINFILE occurrences mentioned previously are separated from one another on the kilometre scale (1 to 4 kilometres). Therefore, it is impossible to make confident correlations between MINFILE occurrences and discuss whether they belong to the same vein, or even mineralized system, as the Ruth Vermont Vein System and associated (interpreted) mineralized halo. Further work will be necessary to continue attempting correlations between the 1996, 2000 and 2003 drill holes within the Vermont Creek valley. However, if the surface and drill data from the 1996 - 2003 exploration programs are taken collectively, and if one accepts the close spatial association between the regional anticlinorium, MINFILE occurrences and geochemical results (rock, silt and soil), then it is reasonable to conclude that the regional anticlinorium is the primary structural control on gold-bearing (and, more generally, base and precious metal-bearing) mineralization. The fact that relatively high grade, gold-bearing MINFILE and regional geochemical data have been documented along, and beyond, a 19 kilometre trend underlying the property are interpreted to indicate potential to identify additional mineralization surrounding, and between, these occurrences. Therefore, one possible conclusion that can be made at this stage in the exploration program is that a large tonnage - low grade gold-bearing potential ore body is a valid exploration target.
For clarification, a high tonnage (or bulk tonnage) - low grade deposit is one in which a large volume of host material contains highly anomalous background levels of gold within which higher grade (to “Bonanza” grade) gold can be found, commonly in the form of veins. For the purposes of the exploration program to date, low grade gold is considered to range between 0.5 and 1 grams per metric tonne and moderate to high grade gold comprises any results above 1 gm/mt.
To summarize, on the basis of Jasper’s exploration results to date, the well documented vein system previously mined at the former Ruth Vermont mine was interpreted to extend north across Vermont Creek, where select mineralized samples associated with quartz veins were recovered. Gold values (plus arsenic plus silver plus lead plus zinc) returned from soil and silt samples are interpreted to indicate a much larger mineralized system than revealed in historical records. The well mineralized Ruth Vermont vein system appears to lie within a much larger gold plus arsenic plus silver plus lead plus zinc mineralized system, coincident with a prominent regional structure and numerous other mineralized occurrences reported in the provincial MINFILE database and historical records.
On the basis of initial interpretation of data arising from the preliminary diamond drill program to evaluate EM anomalies arising from the Fugro Airborne Survey, there appear to be two persistent and well defined graphitic trends, specifically, that comprising the Kaigyn Trend and the Mikayla Trend. The Kaigyn Trend is at least 1.2 km in length and is between 5.7 and 8.8 m thick. The Mikayla Trend is approximately 6.5 km in length and is between 9.2 and 19.4 m thick. The Kaigyn and Mikayla trends are parallel, having an azimuth of approximately 143 degrees and are separated by approximately 1.7 km. Variable bedding orientations measured within some intervals are interpreted to indicate parasitic folding, which may explain the variations in thickness of the two trends. In addition, the presence of moderately well to extremely well developed foliation within the graphitic interval may indicate faults and/or glide planes sub-parallel to bedding which might thin and/or thicken the horizons dependent upon nature and extent of possible fault movement.
Analysis of a total of 145 samples by Acme Analytical Laboratories Ltd and International Plasma Labs Ltd. returned total graphite content from less than 0.02 to a maximum of 1.48% from “high grade” samples, markedly lower than grades interpreted from visual inspection and handling the core. Subsequent analysis of an additional twenty “high grade” samples for analysis and evaluation using X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) at the Canada Centre for Metal and Energy Technology returned the following stunning conclusion:
“The results indicate that graphite, if present, occurs at levels less than 2 wt.% based on the chemical analysis. No graphite could be found by XRD or SEM ...” (Cabri 2006).
As of this writing, further evaluation of graphite has been suspended due to an emphasis on other Jasper properties. However, the results of evaluation of graphite potential on the Vowell Creek property have not been satisfactory in that they are ambiguous and certainly not conclusive.
