Northern Vertex Mining Corp. Provides Hercules Gold Project Exploration Update: Surface Exploration Identifies Four New Target Areas and Potential Links Between Existing Target Areas, Highlighting Property-scale Exploration Potential
Northern Vertex Mining Corp. provided an update on its 100 square kilometer Hercules Gold Project in western Nevada. Integration of recent and historic surface mapping, sampling, drilling, and property-scale geophysical survey data has resulted in the generation of four new verified gold target areas on the property, as well as indicated the potential for links between existing targets. Key Points: Four new exploration target areas, Ursa, Como Ridge, Hades, and Jurassic Park have been identified. A sample from the eastern parts of the Hercules exploration target area returned 72.40 g/t gold and 2,690 g/t silver, making it the highest-grade surface rock sample collected on the property to date. Ongoing surface exploration continues to identify and further delineate structure-hosted epithermal precious metal mineralization in multiple areas, highlighting the exploration potential of the broader Hercules property. Results obtained from sagebrush phytogeochemical line sampling conducted over target areas in the north of the property indicate that they may be linked into one large mineralized system. Notice of Intent (NOI) permits have been received for drilling the Sirens and Como-Comets target areas. Exploration target area prioritization is ongoing ahead of the anticipated third quarter/2021 receipt of an Exploration Area Plan-of-Operations (PoO) permit, which allows for more flexibility in drillhole location, including parts of the new Jurassic Park target. Exploration drilling is planned for fourth quarter of 2021. Geology of the Hercules Gold Project: The Hercules Gold Project, which is located about an hour by car southeast of Reno, consists of a district-scale (approximately 100 square kilometers) property that straddles the flanks of a large collapsed volcanic center in the Walker Lane extensional belt. Gold and silver epithermal-style alteration and mineralization appears to be associated with an extensive volcanic center-related hydrothermal system that was variably controlled by extensional structures and rock permeability, being hosted in veins, vein breccia, vein stockwork, and zones of elevated silica alteration in faults, fractures, and, where available, permeable volcanic and volcaniclastic host rocks. Property-scale curviplanar listric faults concentric about the volcanic center and associated lower order structures represent important exploration targets on the Hercules property, especially where these developed in and adjacent to more permeable rock units. Similar volcanic center-related epithermal gold-silver mineralization systems in the Walker Lane tectonic belt include Round Mountain and Bullfrog. New Exploration Target Areas: Four new exploration target areas have been identified on the Hercules Gold Project through a combination of surface mapping, rock chip sampling, detailed review and integration of the recently reported geophysical data, compilation and integration of historic data, and iterative 3D modelling using available drilling data (recent and historic): Ursa, Como Ridge, Hades, and Jurassic Park. The Ursa target area is in the central parts of the property and targets listric-fault-hosted epithermal-style veins and altered permeable lithic tuff. There are several historic workings in the area. Limited rock chip sampling conducted to date returned gold grades ranging from below detection to 0.71 g/t and silver grades ranging from below detection to 14.6 g/t. The Como Ridge target area is located towards the south of the property, along trend of the historic Como mine. The presence of ledges of vuggy silica, diaspore, alunite, and kaolinite in association with intense argillic alteration indicate the potential for the presence of a high sulphidation-style epithermal system in this part of the property. Numerous historic workings are present in and adjacent to the target area. Limited recent rock chip sampling on the target area returned gold grades ranging from below detection to 1.66 g/t and silver grade ranging from below detection to 2.7 g/t. The Hades target area is in the southernmost part of the property and occurs along a curviplanar listric fault that is along trend of the Como Ridge target area. Historic workings have been found on the target area, as well as epithermal quartz vein float proximal to the large listric fault. Limited recent rock chip sampling returned gold grades ranging from below detection to 4.74 g/t and silver grades ranging from below detection to 70 g/t. The Jurassic Park target area, which is located towards the east of the Hercules and Sirens target areas, contains numerous epithermal-style quartz veins, silicified outcrops, and associated argillic alteration that parallel and may be a splay off the property-scale Pony Meadows curviplanar listric fault. Limited recent rock chip sampling on the target area returned gold grades ranging from below detection to 0.76 g/t and silver grades ranging from below detection to 5.6 g/t. Existing Exploration Target Areas Update: Rock sampling continues to indicate the presence of elevated structure-hosted epithermal gold and silver mineralization in multiple areas across the property, highlighting the exploration potential of the broader Hercules property (Figure 2. Gold in Rock Samples, Hercules Gold Project; Silver in Rock Samples, Hercules Gold Project). Noteworthy observations from the ongoing surface exploration on the Hercules property include: Further delineation of the elevated gold and silver mineralization footprint in the Hercules, Sirens, and Como-Comets target areas ahead of drill planning . Collection a rock sample from the easternmost exposed structure on the Hercules target area, which returned 72.40 g/t gold and 2,690 g/t silver (sample 565923), making it the highest-grade rock sample collected on the property to date. Confirmation of the eastward-dipping curviplanar nature of the major mineralization-hosting structures on the Hercules, Cliffs, Sirens, and Pony Meadows target areas. Rock chip samples were analyzed at the ALS Global Geochemistry Analytical Laboratory in Reno (AU-AA23, Au-AA13, ME-ICP61, Hg-MS42, and Se-MS46 methods). Phytogeochemical Sampling: Phytogeochemical sampling uses vegetation as the sample medium for exploration where regular rock chip, soil, and stream samples cannot be taken due to lack of outcrop, subcrop, or in areas covered by alluvium. Vegetation can scavenge and absorb elements in their roots subsurface and move them to surface where samples are collected. A total of 422 samples of sagebrush were collected along nine biogeochemical lines, following the guidance of Shea Clark Smith/MEG Inc. The sampling covered the Sprite, Lucky Rusty, Rattlesnakes, Loaves, and Northeast target areas.
