Soil Geochemical Results

The Ram soil geochemistry grid is designed to explore a newly discovered showing of strongly brecciated and silicified fine grained subvolcanic felsite exposed as a recent logging road cut east of Victoria Creek. The showing, about 35 km southeast of Quesnel, was discovered in spring 2006 by Mr Peter Bernier. The felsite invades typical Nicola Group altered basalt including dark green, massive greenstone and dense saussuritized pyroclastic rocks. The felsite is very fine grained, leucocratic and holds about 5 to 10 % disseminated pyrite. It is shot through with narrow irregularly oriented fractures, filled with limonite.

Rock samples taken from the showing by Mr Gary Roste were assayed by Eco Tech Labs of Kamloops; they returned moderately interesting results. No significant gold was reported but two rock samples returned 582 and 600 ppm copper.

In June 2006 soil samples were taken by crews working for Richfield Ventures Corp on grid to explore the showing further. Some 708 samples were collected on a grid with 50 m line and sample spacing. Samples were located by GPS coordinates and no grid was cut. The samples were analyzed by Eco Tech labs of Kamloops.

Analytical results, provided by Eco Tech as Excel files, were checked for accuracy and reproducibility from repeat data provided by Eco Tech. Sample tag data were checked and eastings and northings determined from them. These data were prepared for import and plotted in Manifold GIS. Maps were made of the distribution of each metal. Surfaces to show the relief of each metal in map form were prepared and contoured. The diagrams given here are products of this work.

In the maps reproduced here the UTM grid line spacing is 1000 m. Sample localities are represented by small open round circles on a regular grid spaced at 50m. In the metal distribution maps the location of the Ram showing is given by a yellow circle; note that in most metal distributions the Ram showing has no response despite its exciting lithology.

Gold Soil Geochemistry Results

Gold soil geochemistry with anomalous gold results labelled in red. The Ram showing is indicated by the yellow dot. The platinum and palladium response of the grid is uniformly low and not mapped here. Silver is uniformly low on the Ram grid; 1.1 ppm Ag are the highest values seen.

Arsenic Soil Geochemistry Results

Arsenic distribution on the Ram grid with gold anomalous values labelled in red. Note that the arsenic distribution does not follow that of gold. The single high arsenic anomaly is defined by two samples which returned 300 and 205 ppm As on adjacent lines. The next highest As is 50 ppm.

Conclusion and Recommendation

The Ram soil grid is centred on an exciting exposure of pyrite bearing felsic subvolcanic rocks that is shattered, strongly and pervasively fractured and silicified. Gold, copper, molybdenum and zinc values returned from the grid are modest to low and show no relationship to each other or to the known showing. The soil geochemistry does not reflect the felsite occurrence; sodium and aluminum might be expected to be higher where the felsite is known, but this is not the case.

Despite the lack of metal values in the rocks or soils the Ram occurrence is intriguing. Few felsite plugs are known in the Nicola volcanics in this region and the fractured, silicified and pyritic nature makes them especially interesting. The Rusty Ant, Atis and Fireguard showings occur close to the Ram, and are east and north one or two kilometres. They are similar in having disseminated to massive pyrite in felsite or in Nicola volcanic rocks adjacent to or above felsite.

Surprising is the high tin result from two samples and the corresponding yttrium (and titanium) response from the same samples. Tin is uniformly below detection limit in soil samples from the project area and this is the only known high tin geochemical response in this large region.

Soil geochemical sampling is planned for the Rusty Ant, Atis and Fireguard showings and until the results of that work are in hand no further work is recommended on the Ram showing.
