Compilation of Hat Property Data
Doubleview’s review and compilation of available Hat Property data has developed several new areas with exciting exploration potential. More than 2200 data points were generated from historic work and from Doubleview’s more recent work in the area.
Fig. 1 illustrates the occurrences of sulphide minerals as reported by various prospectors and geologists. Doubleview’s work has shown that the presence of Chalcopyrite, Pyrite or a combination of the two, is a useful indicator of significant mineral zones. Magnetite, epidote and chlorite accompany mineralization; the preferred host rocks are andesitic members of the Upper Triassic age Stuhini Group and porphyritic textures are commonly present.
The data points illustrated in Figure 1indicate locations of sulphide mineral occurrences that vary from “small” to “significant”. A 70 meter trench located near the center of the drawing, south of drill hole H-06, more in the center of the map has Pyrite, Chalcopyrite and porphyritic textures throughout most of its length.
On a worldwide basis, the overall size of zones of sulphide mineral occurrences appear to have strong relationships to the size characteristics of the related porphyry deposit. This feature is illustrated in Figure 2.
Open-ring peripheral magnetic lows:
Figure 3 illustrates a fringe of magnetic “lows” peripheral to the zone of moderate to high readings that includes the Lisle Zone. A transition area populated by many sulphide data points includes areas of the exploration interest that recently have been added to the exploration model (Figure 4).
Doubleview’s Experience at Hat Project:
Since optioning the Hat Property in 2011, Doubleview has conducted technical surveys, more than 8300 metres of drilling in 25 drill holes, and a comprehensive data retrieval and compilation. Drilling commenced in 2013 with eleven holes. The Lisle Zone was discovered in drill hole H-8 and confirmed in H-11. Work in 2014 expanded the Zone and showed that “good” gold and copper values occur in areas of intermediate strength induced polarization chargeability. Holes H-11, H-22 and H-23 have persuasive indications that both gold and copper values increase with depth. Step-out drill holes H-14 and H-15, directed to “Anomaly C”, initiated exploration in an area 2 km west of the Lisle Zone. Currently Doubleview is readying an ambitious multi-year program that will further explore overall dimensions of the Lisle Zone, test several targeted sites in the chargeability “transition” areas as illustrated in Figures 4, 5 and 6 and complete archaeological investigations.
Figure 4 illustrates Area F”, a crescent shaped magnetic low feature, aka the “Horseshoe Zone”, proximal to the Lisle Zone, with two areas of chalcopyrite/pyrite mineralization in andesite and porphyritic andesite.
Figure 5 illustrates previously identified (on the basis of geophysics and geochemistry) exploration target areas within the larger highly prospective Anomalies A and E that are now conjoined as “Area A”. The Lisle Zone discovery area is located in the southeast of the drawing. Sites a1, a2 and a3 are diverse and the magnetic and chargeability characteristics of sub-area “E” are very similar to those in the Lisle Zone. Area A has dimensions 4 km by 2.5 km; all five holes drilled in 2013 encountered copper mineralization.
Areas C and D (see Figure 5) located near the west side of the Hat Property have received little attention despite having attractive technical characteristics and numerous reported occurrences of chalcopyrite and pyrite.
Areas G and H, are located in the northern part of the Hat Property (see Figure 6) where there is believed to be a thin cover of Tertiary volcanics (aka Level Mountain lavas). Although magnetic data in such an area may be influenced by the lavas and are somewhat questionable, the induced polarization chargeability/resistivity survey penetrated into the underlying formations to give intermediate strength responses with amplitudes similar to those at the Lisle Zone.
