Goldspot Discoveries Corp. Discovers New Gold System At Quebec Precious Metals' Elmer East Gold Project Using Artificial Intelligence
GoldSpot Discoveries Corp. announce d that Quebec Precious Metals Corporation ("QPM") has successfully discovered a new polymetallic gold rich vein system within one of GoldSpot's high priority targets at the Elmer East project located in James Bay, Quebec. GoldSpot is a shareholder of QPM but does not own any direct interest in the underlying properties. The new discovery borders a regionalscale shear zone previously interpreted by GoldSpot, which opens new multikilometers of potential along strike. The Lloyd showing consists of a 1 to 2 m thick SWNEtrending shallow dipping oxidized quartz vein with various amount of sulphides (galena, sphalerite and chalcopyrite) over a distance of approximately 60 metres. No historical work was previously documented in the vicinity of the discovery. A total of 9 grab samples were collected from the vein, returning gold values ranging from 0.42 g/t Au to 17.75 g/t Au with an average 5.41 g/t Au (Table 1). Grab samples are selected samples and are not necessarily representative of the mineralization hosted on the property. The Lloyd showing are among the highest gold values of the region (cf. SIGEOM database, Ministère des Ressources Naturelles du Québec "MERN"). Silver values averaged 29.2 g/t Ag. Anomalous copper, zinc and lead were also observed with zinc values of up to 7.99% Zn. The goldbearing vein is hosted in a weakly chloritized wacke near the contact with a polygenic conglomerate of the Wabamisk formation. Another anomalous quartz vein grading at 0.33 g/t Au was sampled 400 m east of the initial discovery, demonstrating the continuity of the new gold system along the interpreted WSWESEtrending regionalscale shear zone. One strength of the GoldSpot Smart approach of AI and geological methods to exploration is the ability to take large land packages and distill all available geological information to identify the most efficient and costeffective way to explore prospective terrane. As is standard in GoldSpot's workflow, most of all available public geoscience data was compiled and synthesized for Elmer East property and surrounding areas. Structural, geological, metamorphism, hydrothermal footprint and geophysical components were all analysed through GoldSpot's proprietary AI tools to produce the final highpriority targets for field prospecting (Figure 1). As part of the mandate, GoldSpot's geologists spent one month in the field in the summer 2020 with QPM's geological team conducting a followup field program on the targets. This process included visiting over 400 outcrops, previously identified by GoldSpot's unique AI methods, and recording various rock types, structures, collecting grab samples and documenting a wide range of geological features, which led to the discovery of the Lloyd showing. Behind the Discovery: Refining the Search Area: GoldSpot conducted a desktopbased geological interpretation and a gold prospectivity assessment at the Elmer East project to orient the summer 2020 field exploration program. This study hinged on the digital extraction from a large collection of compiled data including assessment files, government data and academic studies which provided bedrock geology, geochemical analyses, geophysical surveys. Original data was cleaned and combined to create and optimize the data source for all human and machine learning interpretations. Refining the Geological Portrait of the Elmer East Area: The Elmer East project covers Archean greenstone belts and batholiths in the lower Eastmain region of James Bay. The compilation of over 30,000 discrete outcrop observations combined with over 12,000 lithogeochemical samples allowed a reliable revisit to existing largescale geologic mapping resulting in a refined geologic map (Figure 4). In particular, the study highlighted the definition of a hitherto unrecognized clastic sedimentary basin in the Annabelle claim, as well as felsic porphyritic intrusions and ultramafic intrusions in the properties. Lithological contacts juxtaposing rocks with contrasting rheology (e.g. intrusive vs sedimentary rock) is an important factor for vein development, with goldbearing examples in the region, and in particular at the Eleonore deposit area (cf. Fontaine, 2020). The structural reinterpretation, generated using both the 2020 QPM's highresolution aeromagnetic survey and the regional public aeromagnetic survey, highlights subvertical ductile shear systems, which border and transect volcanosedimentary belts; and second and third order structures appear imbricated and flank isoclinal folds in the Annabelle block claim. Structural complexity is widely recognized in Archean gold deposits, including in the James Bay, as a major contributor to the goldbearing vein development (Dube and Mercier Langevin, 2015; Fontaine, 2020). Following the initial interpretation, GoldSpot produced a map index of the perturbation of the azimuth of ductile structures, including the 1st and 2nd order shears and the foliation, which represent the structural complexity of the area. Results highlight an intense structural complexity in the northwestern part of the Annabelle claim, indicating dominant shearing, folding and intersection of both (Figure 5). The updated geological map and global understanding of the area allow GoldSpot to propose a comparison between the Annabelle area and the Eleonore zone (Reserves proven and probable: 1,28 Moz Au; cf. Newmont). Common geological characteristics include: a) a volcanosedimentary sequence, from base to top, basalt, conglomerate, sandstone greywacke and paragneiss, intruded by several felsic intrusions, b) a structural complexity highlighted by intense folding and shearing, c) felsic volcanic and sediment event <2709Ma, and d) a major metamorphic gradient ranging from greenschist to amphibolite superior. Targeting: GoldSpot generated gold targets using a Smart approach combining tacit knowledge and AI datadriven methods. For the latter, the analysis trains machine learning algorithms to predict the presence of gold using all variables (features). Once the model performs to a satisfactory level, results produced include: 1) a series of zones with high probability of containing gold, illustrated in the Figure 1; and 2) a ranking of feature importance for each input feature. The new lithological and structural interpretation was the dominant contribution to the targeting model. Following the targeting, the total area of investigation was reduced by 95%. The Lloyd showing has been discovered in one of the highest proposed priority zones.
