Tier One Silver Commences CSAMT at Curibaya to Refine Copper Porphyry Targets

[{"type":"text","content":"Tier One Silver Commences CSAMT at Curibaya to Refine Copper Porphyry TargetsVANCOUVER, BC / ACCESSWIRE / September 12, 2022 / Tier One Silver Inc. (TSXV:TSLV)(OTCQB:TSLVF) (\"Tier One\" or the \"Company\") is pleased to announce that it has initiated a 35-line kilometre (km) Controlled-Source-Audio-Frequency Magnetotelluric (CSAMT) geophysical survey in the central portion of the Curibaya project in southern Peru. The purpose of this survey is to define the resistivity properties at depth, where zones of lower resistivity and higher conductivity can indicate zones of intense hydrothermal alteration that may be associated with a copper porphyry system at depth (Figure 1). Upon completion of the survey and final targeting the Company plans to drill test for a potential porphyry system underlying the epithermal system defined on surface. Currently, results are pending from a channel sampling program to refine precious metals targets within the newly permitted Cambaya target area.A Message from Peter Dembicki, President, CEO and Director:\"The CSAMT geophysical survey is a key component to learning more about potential copper porphyry mineralization, which we saw indications for in our first phase of exploration at Curibaya. This is an exciting development for the Company toward unlocking the large opportunity of a potential copper porphyry deposit alongside the epithermal silver system that we've already identified, and we look forward to defining these targets for our next drill program.\"Copper Porphyry Potential:The first phase of drilling and surface work has provided several lines of evidence that a porphyry target exists in the central region of the mineralized system, as it is currently defined. An analysis of vein geochemistry across the property has demonstrated concentric zonation with copper-lead-zinc zoning outward into lead +/- copper and then zinc +/- lead in the peripheral zone (Figure 1). This geochemical zonation is consistent with porphyry systems and the central copper-lead-zinc zone would be the primary target area at depth. Within the copper - lead - zinc geochemical core, skarn mineralization is observed on surface, indicating a proximity to intrusives. Small scale 1 - 2 metre (m) wide porphyry dykes and associated magnetite veinlets were intersected in the phase I drill program within the Madre and Tipal str...
