Targeted IP Survey At The “A” Zone At Ishkoday
TORONTO - Laurion Mineral Exploration Inc. reported the commencement of an Induced Potential (IP") survey as strategic part of the 2020 exploration program at the Corporation's wholly-owned Ishkoday Project, located 220km northeast of Thunder Bay, Ontario.
Field crews are on-site cutting the grid for 40km of lines for the geophysics Survey over the Sturgeon Mine and the "A" Zone target sector, as well as the newly acquired Brenbar Project located due west of and on trend with the Ishkoday Target Area. The objective is aimed at refining targets for the upcoming diamond drilling campaigns testing the "bulk" gold/gold-zinc potential. The survey will assist in: (1) Reconstructing the primary geological elements (rock types, contacts) and secondary ones (fault/shear zones, alterations, and quartz, oxide-sulphide and sulphide vein mineralization); and (2) Predicting the surface strike (horizontal) and depth (vertical) extensions of the gold and gold-zinc mineralized vein corridors beyond the known dimensions.
2019 exploration work identified 3 major gold-mineralized trends, Sturgeon River Mine, M25/Marge and Loki, which extends along strike for 2+km, 1.8+km and 3+km, respectively. The 2018 and 2019 channel and selected grab sampling campaigns returned a substantial number of significant gold and gold-silver-zinc assay results which not only validated historical sampling but also greatly expanded the target strike lengths. These results indicate that the gold-mineralizing event, or events are very widespread. The historic Sturgeon River Mine data further suggests that mineralization may be more extensive at depth.
The company is now in a position to pursue these 3 target areas with targeted drill programs and surface work in 2020 to expand our evaluation of these important trends.
The 3 main mineralized trends occur in the 5km by 1km Target Area located in the southern claim block of Ishkoday, and are characterized by: An early hydrothermal system, termed the Ishkoday-style Mineralization, hosting stockwork-style NE trending veins of magnetite (magnetic iron oxide), quartz, sphalerite (zinc sulphide), gold and silver (the "Oxide-Sulphide Veins”); In addition, there are multiple sphalerite-rich (zinc sulphide) centimeter to meter wide veins, also containing pyrite (iron sulphide), chalcopyrite (copper sulphide), galena (lead sulphide), gold and silver (the "Sulphide Veins”); The Oxide-Sulphide and Sulphide Veins are centered on the "A" and CRK Zones of the known 3+km by 800m "Loki Trend Corridor" (the "Loki") as defined by over 26,000m of previous drilling covering more than half the Target Area.
The priority target within the Loki is the 50+m wide "A" Zone Sulphide Veins. A later gold-dominant event linked gold-silver bearing quartz veins, termed the Sturgeon River-style Mineralization, in two known corridors: the 2+km by 300m "Sturgeon River Mine Corridor" and 1.8km by 350m "M25-Marge Corridor".
In the Sturgeon River Mine Corridor, compilation and synthesis of the historic Sturgeon River Mine underground data, and the mapping/sampling of the No. 3 Quartz Vein and adjacent veins suggest that the 1937 to 1942 mining from near surface to -530m vertical depth not only covered the N-S trending No. 3 Quartz Vein, but also 5 other quartz veins, most of which trend NE-SW.
Drilling in 2010 intersected several additional quartz veins north of the underground workings. Laurion is of the opinion that higher-grade gold-bearing veins ("Shoots") are present at the Sturgeon Gold Mine. Current compilation work with the defined I.P. survey will help define other potential target Shoots for future drilling.
