The Slam Property is underlain by deformed Permian(?) limestone and Carboniferous(?) metavolcanic rocks which are intruded by feldspar porphyry dikes. In the area, tuffs, phyllites, siltstone, greenstone and limestones are underlain by Permian limestones of the Stikine Assemblage. These rocks are intruded by three igneous events, which include foliated diorite of Triassic age, unfoliated diorite of Jurassic age and feldspar porphyry basaltic dykes of the Sloko Group of Cretaceous to Tertiary age.
The Permian limestone is pervasively silicified with local areas of dolomitization and brecciation. The limestone contains irregular areas of chert and pyrite. The dolomitized limestone is often intensely stockworked by quartz and calcite veins.
Gold mineralization is associated with a northeast trending, northwest dipping silicified limestone unit, in contact with an altered tuff unit. A 200 by 30 metre, silicified, well fractured zone, contains disseminations and blebs of pyrite. The silicified limestone is likely fault bounded on the west.
Several rock samples from the silicified zone assayed over 1.0 gram per tonne gold. A one metre chip sample from the zone assayed 1.33 grams per tonne gold, 10.7 grams per tonne silver, 44 grams per tonne mercury, 3600 grams per tonne arsenic and 280 grams per tonne antimony (Assessment Report 12775). A sample of silicified limestone with malachite staining, 600 metres to the west-northwest, assayed 2.4 grams per tonne gold, over 100 grams per tonne silver and over 1000 grams per tonne antimony (Assessment Report 12775).
Two HQ holes were drilled totalling 283 metres. The target on this property was a large body of silicified limestone which had been geologically mapped, sampled and trenched. The target was silicified limestone which had surface gold values up to 3.8 grams per tonne along with very high arsenic, antimony and mercury values (Assessment Report 16726). The targeted silicified limestone was note intersected at depth.
In 1983, three claims, Slam, Grand and Strike, were staked by Chevron Canada Ltd and a small geochemical survey consisting of the collection of 190 soils samples was conducted (Assessment Report 11818).
In 1984, geological mapping (1 :2500 scale), a large geochemical survey (1631 soil samples), five cat trenches and a VLF survey over the entire grid were completed by Chevron Canada Resources Ltd. (Assessment Report 22697) . The trenches and VLF survey were reported only as part of the history of the property in the 1992 assessment report and not mentioned at all in the 1984 assessment report (12775).
In 1987, hole S-39 was drilled for Chevron Canada using HQ core but still encountered severe problems and was lost at 111.86 meters. The drill was moved back one foot and S-39A was collared. It was tri-coned to 111.86 meters and then cored to the end of the hole. A surprising amount of highly clay altered feldspar porphyry was encountered in this hole despite the fact that none was found on surface. A good intersection of silicified limestone had been anticipated and it appeared to the Chevron geologists that the drill hole had glanced off the side of the silicified limestone, suggesting that the target was never tested (Assessment Report 16726).
In 1991, North American Metals Corp., for Chevron Minerals Ltd., conducted detailed mapping (1:1000) and 43 chip samples over known mineralized areas (Assessment Report 21964).
In 1992 North American Metals Corp completed 8 line kilometers of Induced Polarization surveying on the Slam property (Assessment Report 22697). In general, the results were not deemed encouraging.
Paget Resources Corporation conducted a one day sampling and mapping program in 2007. 18 rock samples were taken from the main silicified limestone units and from outcrops north of the main zone. A 1:5000 geological map was also produced. Fifteen of the eighteen rock samples were taken from silicified limestone breccia in the main 250 by 400 metre zone of silica alteration in the central part of the property. The samples include both oxidized and unoxidized mineralization. Limited rock sampling carried out in 2007 suggests that base metals and epithermal indicator elements are variably elevated within the zone, while precious metals are generally low.
In 2011, the Slam property was examined Paget Minerals Corp for three days. The purpose of the visit was to evaluate the economic potential of the claims by validating the location, style and potential of known mineralization as presented by previous workers in the area. Previous work in the area was located and registered in GIS software for future use. A drill location was selected for future use.
