Gitennes Exploration 2017
Gitennes commenced exploration on the Snowbird property in mid-July. With little to no exploration having been completed on the property for almost 28 years Gitennes’ initial phase of work was orientation and reconnaissance. Upon completion of the initial phase of work, exploration consisted of detailed mapping and sampling of the Main Zone, soil sampling, primarily over the Main and North Zones, sampling and mapping of the East Zone and a ground magnetometer survey over the Main, North and East zones.
Rock sampling was carried out in the course of specific investigations into the Main Zone and other prospective zones/areas reviewed in the course of the reconnaissance aspect of the programme. 123 rock samples were taken and analyzed for 51 elements.
127 soil samples were taken by hand auger. All samples were delivered to ALS Global of North Vancouver and analyzed for 53 elements. Three tranches of soil sampling was carried out in the latter phase of the ground exploration programme.
Tranche 1 Samples taken over and east of, the Main Zone.
Tranche 2 Samples taken in order to assist in identifying where gold mineralization might outcrop based on the projection of mineralization intersected in the course of the 1986-’89 drill programme – specifically in the North Zone.
Tranche 3 Follow-up of samples that were identified as having anomalous levels of Sb / As in Tranche #2 sampling.
Figures 1 and 2 below illustrate the location of the southwestern component of the soil sample programme where anomalous arsenic and antimony results were identified. The results are plotted over a background of the ground magnetometer survey. Anomalous results are coincident with a mag low. Mag lows are consistent with lithologies which have been de-magnetized as a result of intense carbonate-silica flooding. This is a characteristic of the listwanitwe seen elsewhere on the property.
Ground magnetometer survey
A high resolution ground magnetometer survey was carried out in July and September 2017. A total of 51.3 line kilometres were read.
The data obtained from the ground magnetometer survey over the Snowbird Gold Property was of high quality and outlined significant magnetic features of interest. The main NW-SE zone of de-magnetized ultramafic rock, historically referred to as the Mariposite Alteration Zone (MAZ) zone is readily traced across the extents of the surveyed area. Obvious structural breaks occur in the data predominantly in north, NNW and NE orientations (Figure 3). This is confirmed by field measurements. A significant change in geophysical signature occurs at the end of the “Main Zone” near the stibnite vein separating the Main and North Zones (marked as a strong black line in Figure 4). As a preliminary interpretation it appears that a possible vertical down drop of the zone occurs in this area. In the North Zone the signature of the MAZ is significantly weaker possibly reflecting a deeper source. A repetition of geological sequences (from south to north – mag high/ mag low to mag low/mag high) along the longer lines suggests a possible synformal sequence that may host the Main Zone. This can also be noted from field observations. Structure will most likely be key to finding high grade gold intersections and understanding why previous drill holes did not intersect Au mineralization.
