Golden Spike Resources Corp. Announces Results of Induced Polarization/Resistivity Surveys Completed At 100%-Owned Gregory River Copper-Gold Property in Western Newfoundland
Golden Spike Resources Corp. announced the results of Induced Polarization/Resistivity surveys completed at its 100%-owned Gregory River copper-gold property in western Newfoundland. The IP surveys were designed to target volcanogenic massive sulphide mineralization, as well as vein-hosted and disseminated sulphides, and the results have been very positive, identifying multiple, high-priority chargeability and resistivity anomalies. The IP results, in conjunction with compiled geological and geochemical data, historical drilling data, and a previous IP survey at Lode 9, have been used to generate proposed drill hole locations at Steep Brook, Lode 9 and the Vein Zone. Drill pad construction teams are currently mobilizing to site, and the Company is expecting to commence its inaugural diamond drilling program later this month. The recent IP surveys at Steep Brook (11 line-km) and the Vein Zone (4.5 line-km) were completed by Simcoe Geoscience, based out of Stouffville, Ontario, between July 14 and August 5, 2024, using their "Wireless" Time Domain Distributed IP Technology. The data was collected using a "dipole-pole-dipole (Reverse & Forward)" configuration with a 50 metre ("m") station spacing and extra current injections at both ends of the profiles for additional depth penetration. This achieved depths of investigation exceeding 300 m at Steep Brook and 400 m at the Vein Zone. Simcoe also re-processed and interpreted the IP data from the 2023 survey over the Lode 9 target and generated priority IP targets at all three areas. Steep Brook IP Survey Steep Brook is located in the southern portion of the VMS target corridor and is underlain by a north-northeast trending sequence of the Lower Ordovician-aged basaltic flows and related volcaniclastic rocks with widespread chlorite +/- silica-carbonate alteration. These rock units are thought to define part of a broad, gently plunging syncline, with associated local anticlinal fold pairs. Outcrop exposure is limited to a few creek beds, where intermittent outcrops of disseminated, veinlet hosted and semi- massive chalcopyrite-pyrite mineralization have been mapped. Previous interpretations suggest that this mineralization could represent a footwall, copper- rich stringer zone to an as yet undiscovered copper-gold-zinc massive sulphide deposit. The Steep Brook IP survey included 11, east-west oriented lines, each 1,000 m in length and separated by 100 m. The survey revealed a "corridor" of subparallel, variably oriented, anomaly trends that cover the entire 1,000 m length of the IP survey, over a width of approximately 375 m, and remains open to the north and south. The two major anomaly trends, AT1 and AT2, can be traced over lengths of 700 m northeast, and 600 m northwest, respectively and along these trends are a total of 15 first priority, IP generated targets. In addition, there are three, shorter anomaly trends, AT3, AT4 and AT5 that have interpreted lengths of 200 to 300 m and contain ten additional first priority targets. Surface projection of the IP anomaly trends coincides with the >100 ppm copper soil anomalies (historically collected by Noranda in 1991) and multiple historical rock samples that assayed up to 19.6% copper (average 3.3%), 27.4 g/t Au (average 1.06 g/t Au), 11.1 % Zn (average 0.23%), and 20.3 g/t Ag (average 5.2 g/t Ag). According to interpretations by Simcoe, the First Priority IP anomalies are generally of moderate size (100m x 100m) and exhibit a moderate-to-strong increase in chargeability response (>6 mV/v), accompanied by a marked decrease in resistivity (<2000 Ohm-meters). These anomalies are at moderate depths and interpreted to be consistent with disseminated to semi-massive sulphide with potential for VMS and Cu-Au vein mineralization. Golden Spike is planning to drill approximately 6 holes, totaling 1,000-1,200 m testing several of these first priority IP anomalies at Steep Brook. Vein Zone IP Survey; The Vein Zone is located in the northeast portion of the Property and is mostly covered by a veneer of soil and till, with only a few outcrops exposed along ridges and in creek beds. Where exposed, mineralization is dominated by a series of northwest to southwest striking quartz-carbonate-sulphide veins that range from approximately 0.5 m to 2 m in width, and locally as much as 5 m - 6 m. Copper grades are of the veins very high and range between approximately 1% to 25% copper (average approximately 2% to 6% copper), along with associated gold (ranging between 0.1 g/t and 3 g/t) and anomalous values of zinc and arsenic. Work by the Company confirms that historical surface sampling might not have tested the full potential width of the vein systems and that historical drilling from the 1950's at Court A only sampled the highest-grade portion of the veins, leaving most of surrounding host rock unsampled. The Company believes that potential exists for wider, mineralized haloes to surround the main veins and for the discovery of new veins hidden below surface soil and till cover. The IP grid is in the southeast corner of the Vein Zone and is comprised of three, 1,500 m long, north trending lines, separated by 200 m. The survey was designed as a test to determine the effectiveness of IP as an exploration technique for the vein-style mineralization and whether the mineralized envelope could be wider than the historical sampling indicated.
