McBride Property Geochem Survey
For complete information concerning the McBride River Property please click here to review in detail the November 2005 McBride River Geophysical Report prepared by Laurence Stephenson, P.Eng. and updated in April 2007.
In conjunction with the grid geophysical survey, a geochem soil sampling survey was completed this in July of 2005. Samples were taken along the 100-metre spaced grid lines at 25-metre intervals by field workers of Nicholson and Associates, the exploration contractor, and placed in brown Kraft paper bags, dried and shipped to Acme Analytical Laboratories (“Acme”) in Vancouver for analysis. Sampling procedures were observed by the author of the Report and are correct to industry standards. Acme is a qualified and fully accredited assayer. The results reflect a true soil analysis profile.
Some of the soil conditions in the higher (eastern) part of the grid were reported as “difficult” due to the scarcity of a developed soil profile. This factor is considered in the analysis of the data.
The data as presented demonstrates a high background in base metals, especially zinc, throughout the McBride Property, with specific zones of interest delineated, although continuity between highs is less cognizant. With respect to the gold sampling, it appears that very little continuity between samples is present, possibly reflecting the low relief of the upper plateau region and the dissection by numerous streams. Spot highs are adjacent to low values and the immediate area of the Discovery Vein was not anomalous. Correlation of high gold values to base metal values is almost non-existent except for a few isolated instances.
It is the opinion of the author of the Report that the relief and the vegetation observed would lead to isolation of sample highs and therefore this lack of continuity and correlation should not be considered negative and all high gold values should be re-visited.
Gold Soil Geochem Anomalies
Several zones with soil values of gold in the 100+ ppb range (in general gold soil geochem results were in the 0 to 7 ppb range) were noted and are suggested for follow-up. Although in most instances the anomalies are not continuous, their magnitude and other factors outlined below warrant follow up.
The gold soil geochem anomaly AU I (2 points +100 ppb) is located in the south east portion of the grid adjacent to the Base metal soil geochem and the off grid trending magnetics anomaly EE. The location of the "B" Vein 600 metres to the south, the existence of two spot gold anomalies (+100ppb) and the favourable volcanic geology makes this area worthy of further exploration work.
The gold soil anomaly AU II (3 widely separated points +100 ppb including the highest of 561.3 ppb) is located 500 metres northeast of the Discovery Vein and adjacent to the magnetic anomaly BB south end. The wide separation and distance from the main vein is caused by various creeks and low relief topography in between and therefore represents some interesting targets.
The gold soil anomaly AU III (2 separated points one + and one almost at 200 ppb) is associated with the base metal zone and magnetic anomaly CC. The magnitude of the gold geochem and potential contact geology of the area is noteworthy.
The gold soil anomaly AU IV (1 point +350 ppb is the second highest) is on trend with another "anomalous" sample with the showing "D4" (Vein "C") on the main "camp" creek approximately 300 metres to the north. Although the "D4" showing has low gold values the trend and magnitude of this zone is of interest.
The final gold soil anomalies AU V and VI (1 point +300 ppb and 2 points + 200) are in an area of contiguous elevated to anomalous (+ 20-50 ppb) values of gold in the western area of the McBride Property, mapped as volcanics that has not been explored in detail.
Four base metal rich zones were identified that are of interest due to the juxtapositioning of magnetic and/or geological and/or gold soil geochemical features. They include the soil base metal anomaly associated with gold soil anomaly AU I (BM "B") and with gold soil anomaly AU III (BM CC) outlined above and two base metal anomalies flanking the Discovery Vein and associated with the magnetic high area in the western part of the grid (BM MagN and BM MagS). All these "anomalies" showed continuity over a few stations and adjacent lines mainly outlined by the zinc values of +250 ppm. That three of them are apparently open off grid to the southwest is also worth noting for follow up.
