The Zone 1-South Area surface gold showings and the Zone 3 surface gold showings occur within the mixed meta-sedimentary lithologies consisting of, conglomerate, arenite greywacke, and minor mudstone of the Indian Lake Group (I.L.G.). Recent geochronological age dating by Ayers et al 2013 indicates that the I.G.L. is 2690-2680 Ma and Archean aged and is therefore part of the Porcupine assemblage. This new interpretation is based on age determinations from felsic volcanic rocks and intercalated clastic meta-sedimentary rocks very close by and near the property boundary to the north. Intermediate to felsic intrusive rocks were also dated as 2687-2686 Ma and are synvolcanic with the I.L.G. of Porcupine volcanic and meta sedimentary assemblage.
The I.L.G. meta-sedimentary lithologies exhibit spectacular bright red to maroon red jasper grit, granules, pebbles to boulders that are also very commonly found in the slightly younger Timiskaming assemblage (2676-2670 Ma) that also commonly occur within the regional significant gold camps both, at and near Kirkland Lake and Timmins, Ontario.
The Zone 1-South Area was drill tested with 5 diamond drill holes totaling 1258 meters and were completed with approximately 251 meters per hole in February 2019. All drill holes intersected the Archean aged I.L.G. clastic meta-sedimentary lithologies including mudstone, arenite and conglomerate that have been intruded by intermediate composition hornblende porphyry aplite dikes and by felsic composition feldspar quartz porphyry dikes. Early Proterozoic narrow diabase dikes with finely disseminated magnetite and exhibiting a moderate to strong magnetic signature cut the meta- sedimentary lithological sequence locally.
Assay results for the 5-diamond drill hole program seems to indicate that the gold mineralization encountered to date appears to be part of, proximal to and within an extensive large near surface hydrothermal alteration mineralizing system. The nature of the Indian Lake Group meta-sedimentary lithological sequence near Zone 1 & Zone 3 exhibits a strong to extensive presence of a coarse clastic sedimentary polymictic conglomerate unit. This pebble to boulder conglomerate that also includes red jasper clasts appears to have acted as a superb permeable and porous favorable host rock for hydrothermal fluid migration, alteration and eventual deposition of disseminated pyrite and gold.
The ddh’s that carry variable gold mineralization tends to be associated with fine grained disseminated trace 5% pyrite and occasionally with trace chalcopyrite locally. This mineralization occurs within all of the meta-sedimentary lithologies and is especially associated within all of the meta-sedimentary lithologies that exhibit strong pervasive hydrothermal alteration. This alteration consists of pervasive bleaching and silicification, flecks wisps and filament lamellae of sericite and fuchsite sericite imparting a ‘green carbonate’ alteration locally, ankerite veinlets, chlorite healed micro-fractures and stringers, quartz stringers and veinlets, quartz ankerite stringers and veinlets, and locally pervasive interstitial calcite and calcite stringers. Peripheral to moderate to strong hydrothermal alteration zones are the more flanking and more distal weaker alteration zones that consist predominantly of calcite stringers and veinlets as well as locally pervasive to patchy interstitial calcite, and locally weak epidote.
Thus, the objective of this survey is to detect sulphide-rich (mainly chalcopyrite and pyrite) mineralized zones that may contain gold mineralization associated with a hydrothermal alteration system. Sulphide minerals such as pyrite and chalcopyrite produce strong and easily detectable Induced Polarization (IP) anomalies, particularly in a disseminated style. A deeply exploring Induced polarization method such as OreVision® is therefore an appropriate tool for this exploration program.
