10/16/2019 (T Pettigrew) - Trenching by F. Houghton in 2003 revealed the presence of volcanics (to the south) and a heavily altered, carbonated, feldspar porphyry intrusion (traced for 600 metres) separated by an Iron Formation of varying widths. This "contact body" which separates the volcanics from the porphyry is heavily cut by quartz stringers, veins and veinlets. Sampling within the trench locations tested both the quartz veins and Iron Formation. Sampling has revealed that gold mineralization parallels the south side of the porphyry or near the contact with the volcanics separated by iron formation (Assessment report 42E12NW2025). The sheared and altered BIFs contain quartz-carbonate veins and stringers running parallel or sub-parallel to the general structure. Veins and veinlets are common throughout the prospect, but their thickness and texture vary significantly from a few millimeters or centimeters to as much as 1.5 meters. The veins commonly have pinch-and-swell structure, and locally form discontinuous lenses. Quartz is essentially white in colour, but may be locally stained by iron oxides and iron oxy-hydroxides that lend it brown to ochre colouration. The vein quartz is commonly crystalline, whereas the quartz in the banded iron formations has saccharoidal texture. Where accompanied by significant sulphides, the vein quartz can be vuggy. Typically, mineralized areas have been identified where there is evidence of strong oxidation with limonite and gossanous features. The BIFs at Gwyn Lake belong mainly to arsenical-silicate facies. Locally the BI's are enriched in manganese (e.g. Camp Lake showing) (Assessment report 20000005755).
