Tier One Silver launches CSAMT in Curibaya to refine copper porphyry targets


VANCOUVER, BC / ACCESSWIRE / September 12, 2022 / Tier One Silver Inc. (TSXV: TSLV)(OTCQB: TSLVF) (“First level“or the”Company“) is pleased to announce that it has initiated a 35 line-kilometre (km) controlled-source magnetotelluric geophysical survey (CSAMT) in the central part of the Curibaya project in southern Peru. The purpose of this survey is to define resistivity properties at depth, where areas of lower resistivity and higher conductivity may indicate areas of intense hydrothermal alteration that may be associated with a copper porphyry system at depth (Figure 1). Potential Porphyry System Underlying the Surface-Defined Epithermal System Currently, results are expected from a channel sampling program to refine precious metal targets in the newly licensed Cambaya target area.

A message from Peter Dembicki, President, CEO and Director:

“The CSAMT geophysical survey is a key piece of learning more about potential copper porphyry mineralization, for which we saw indications during our first phase of exploration at Curibaya. This is an exciting development for the company to unlock the large potential copper porphyry opportunity next to the epithermal silver system that we have 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 currently defined. An analysis of the geochemistry of the veins across the property demonstrated concentric zoning with copper-lead-zinc zoning outward to lead +/- copper and then to 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 main target zone at depth. Within the copper-lead-zinc geochemical core, skarn mineralization is observed at the surface, indicating proximity to intrusives. Small-scale porphyry dykes 1 to 2 meters (m) wide and associated magnetite veinlets were intersected in the Phase I drilling program in the Madre and Tipal structural corridors, also indicating the potential for a porphyry proximal. Additionally, drill holes 6 and 8 had molybdenum (Mo) intersections grading 5 m at 85 ppm Mo and 44 m at 52 ppm Mo, respectively, providing a potential vector to a porphyry system at depth (Figure 2). Collectively, this evidence supports continued targeting and guidance work toward a porphyry system at depth.

An analysis of the geochemistry of the veins across the property demonstrated concentric zoning with copper-lead-zinc zoning outward to lead +/- copper and then to zinc +/- lead in the peripheral zone. This geochemical zonation is consistent with porphyry systems and the central copper-lead-zinc zone would be the main target zone at depth. In addition, the magnetic and chargeability anomalies shown in the figure could represent potassic intrusion or alteration and sulphidation at a depth of approximately 400 m, respectively.

Figure 2: Illustrates the conceptual geological model of the mineralization of the Curibaya project. Importantly, the higher elevations are interpreted to represent an increase in the vertical extent of precious metal mineralization with a porphyry target at depth, between the Sama and Sambalay corridors, as evidenced by: zonation geochemistry in vein geochemistry, skarn mineralization observed at low elevations. near the Madre corridor, molybdenum increasing with depth in holes 6 and 8, as well as the presence of magnetic anomalies at approximately 400 m depth.

Additionally, the Company announces that it has engaged Native Ads Inc. (“Native Ads”) of Vancouver, British Columbia, a digital media expert firm, to execute a comprehensive digital media marketing campaign supporting Tier One’s ongoing efforts to increase awareness.

Curibaya drilling

Analytical samples were taken by sawing HQ or NQ diameter cores into equal halves on site and sent one of the halves to the ALS laboratory in Arequipa, Peru for preparation and then to Lima, Peru for analysis. All samples are analyzed using a 30 g nominal weight fire assay with atomic absorption finish (Au-AA25) and the four-element multi-element acid digestion ICP-AES/ICP-MS method (ME-MS61). When MS61 results were above or near 10,000 ppm Cu, 10,000 ppm Pb, or 100 ppm Ag, the test was repeated with the grade four (Cu, Pb, Ag-OG62) acid digestion method. When OG62 results were above or near 1500 ppm Ag, the assay was repeated with a nominal 30 g weight fire assay with gravimetric finish (Ag-GRA21).

QA/QC programs for 2021 core samples using company and laboratory duplicates, standards and blanks indicate good accuracy and precision in the vast majority of standards tested.

True widths of mineralization are unknown based on current geometric understanding of mineralized intervals.

Channel Sampling – Curibaya

Analytical samples were taken at every 1 meter interval from the channel bottom, yielding approximately 2-3 kg of rock chips per sample. The samples collected were sent to the ALS laboratory in Arequipa, Peru, for preparation, and then to Lima, Peru, for analysis. All samples are analyzed using a 30 g nominal weight fire assay with atomic absorption finish (Au-AA25) and the four-element multi-element acid digestion ICP-AES/ICP-MS method (ME-MS61). When MS61 results were above or near 10,000 ppm Cu, 10,000 ppm Pb, or 100 ppm Ag, the test was repeated with the grade four acid digestion method (Cu, Pb, Ag-OG62 ). When OG62 results were above or near 1500 ppm Ag, the assay was repeated with a nominal 30 g weight fire assay with gravimetric finish (Ag-GRA21). QA/QC programs for channel 2021 samples using internal standard samples and blank samples; field and lab duplicates indicate good overall accuracy and precision.
