The Paola occurrence is part of the Grouse Mountain (Julia) (093L 251) property. The area is underlain by Lower Jurassic Hazelton Group volcanics (Telkwa Formation), comprised mainly of a uniform, fine-grained maroon tuff overlain by a sequence of tuff, lapilli tuff, tuffaceous greywacke and argillite. The tuffs range from dark grey to green to maroon and are fine-grained, thinly bedded, laminated or massive. These are underlain by massive green andesitic to dacitic flows.
The volcanic rocks are altered hosting mica, chlorite, and clay minerals with less common, epidote.
The Hazelton rocks are intruded by a series of feldspar porphyry dikes trending north-northwest and west dipping ranging between 30 to 70 metres in width. Basic lamprophyre dikes also crosscut the volcanics.
The Paola quartz vein infills a shear in altered and bleached maroon tuff with an alteration zone of approximately 8.0 metres in width. The vein strikes north and dips 30 to 40 degrees west hosting a 2.0 metre wide section of disseminated malachite staining in an open cut. In 1984, four samples taken over 1.0 to 1.2 metres assayed 67.5 grams per tonne silver and 0.36 per cent copper (Assessment Report 13364).
Just north of the Paola mineralization, tetrahedrite is exposed in the silver showing. The mineralization is contained within a quartz-carbonate infilled shear zone (see Assessment Report 13364, Figure 3)
Work History
In 1984, Adriatic Resources carried out 26 diamond drill holes, (total depth of 1170 metres), geological mapping, geochemical soil surveys, and geophysical VLF-EM surveys. The results indicate relatively higher grades of silver bearing mineralization are associated with relatively higher copper-lead-zinc values. Relatively higher gold values have a positive correlation with increased copper percentage. Due to a lack of 3D data and understanding of the distribution of mineralization, it is not known whether these intervals represent true width. Work done by Adriatic Resources in 1984 indicates the presence of variable and relatively narrow drill intercept intervals (0.07 to 0.76 metre) of elevated silver values and lesser gold associated with copper-zinc bearing minerals over a vertical distance of less than 30 metres and strike length of less than 200 metres on the Julia (aka Last Chance) quartz-sulphide fissure vein occurrence. Drilling occurred on the Christian (4 holes) and Paola (2 holes; 84-10 and 84-13)(Assessment Report 13364).
In 1991, AIC International Resources Corporation drilled a total of 264 metre was in two holes. The IP survey on the Chance Property (Julia) outlined a 1350 metre long chargeability anomaly up to 650 metres wide open to both the north and south. Geophysics appears to have been done on the Julia and the Paola areas and immediately south of the Christina (093L 295).
In 2010, rock chip/soil sampling, mapping, and surveying were carried out (Assessment Report 31644). A 2000 metre long by 1000 metre wide area was surveyed by east-west oriented grid lines in 8 follow-up soil anomaly zones. The 2010 soil grids focused on areas adjacent to intrusive contacts that returned anomalous copper-zinc-silver-gold values in the 2009 soil survey. A total of 34 soil samples and 9 rock chip samples were taken. Rock chip sample from the Christina showings (093L 295) (GM10AR-53) contains elevated gold-arsenic, and two rock chip samples from the Paola showings (093L 296) contain elevated copper-silver (GM10AR-55) and elevated lead-zinc (GM10AR-56). Results from geochemical analysis of 54 soils taken in 2010 indicate there a few weak strength anomalies in zinc-silver-gold-arsenic present.
