VANCOUVER, BC / ACCESSWIRE / October 21, 2024 / Tier One Silver Inc. (TSXV:TSLV)(OTCQB:TSLVF) ("Tier One" or the "Company") is pleased to report new channel sampling results from its priority silver-gold corridors Cambaya I and Cambaya II. The Cambaya structural corridors, located in the northeast area of the property, represent highly prospective precious metals target areas, identified through extensive surface sampling.

In comparison with other targets within the property, Cambaya is higher in topography, (approximately 2,400 metres above sea level ("masl")), higher in stratigraphy (Toquepala volcanics) and is believed to be located in the upper part of the epithermal system due to the occurrence of more extensive high grade precious metal samples and high arsenic anomalies (>100ppm). This is accompanied by the presence of lower temperature silica and quartz vein colloform textures.

Peter Dembicki, CEO and Director of Tier One commented, "The Curibaya project represents extensive high grade silver veins and rock samples. The work we have completed to date at the Cambaya I, II and Zone 1 targets supports our thesis that we are targeting the preferred precious metals zonation of an epithermal system. The recent channel samples expand our target area by 350m in width; the Cambaya corridors now have a total of 1.75 kms x 950m area of prospective precious metals zonation with grades up to 8,950 g/t Ag."

"We have been patient with our anticipated next phase of drilling as a result of a weaker silver market which is finally improving. We are looking forward to our next drill program to test our most prolific and prospective targets within Cambaya."

The Company's recent surface exploration program was designed to expand the highly prospective precious metals targets and enhance the thesis that Cambaya sits at the preferred zone of an epithermal system. The program consisted primarily of channel sampling and mapping and was successful in delineating additional drill targets for a drill program anticipated for later this year. At Cambaya I, 48 samples were taken from 10 trenches in 200m x 200m areas. At Cambaya II, 53 samples were taken from 17 trenches, in 250m x 500m areas.

Table 1: Highlights from the exploration work include (Figure 1):

Figure 1: Illustrates location of the recent channel sampling (highlighted in yellow), a geophysical MAG map of the Curibaya area and the location of the two main corridors, Cambaya I and Cambaya II.

The Cambaya structural corridors are located in the northeast area of the project (Figure 1), which is the highest target in topographic elevation (2,400 masl) and within the epithermal system with highly elevated arsenic values and low temperature colloform silica textures (Figure 2), indicating that the potential of a precious metals horizon is being preserved at shallow depth (see NR dated September 26, 2022).

Figure 2: Illustrates occurrence of different quartz / silica textures within the Curibaya Project. Cambaya, located in the NE area (blue polygons), shows more occurrence of quartz colloform textures that, in combination with high arsenic anomalies, is consistent with the upper part of an epithermal system.

Table 2: Highlights from previous channel sampling (see NR dated October 14, 2021 and September 26, 2022) in these corridors include:

The intention of ​​this exploration campaign was to investigate the occurrence of silver and gold mineralization in new zones of veinlets and breccias within the corridors. With samples returning grades of up to 8,950 g/t Ag and 4.13 g/t Au, the results demonstrate that there is mineralization in new areas within the epithermal corridors. These high-grade areas, upon finding permeable zones within the 400 - 500 meters of the volcanic unit, may create ore shoots or disseminated zones as observed in previous sampling at Cambaya with 20 meters of 242.7 g/t Ag and 0.71 g/t Au in channel sample 21CRT-55. These main structures or corridors are characterized by an opening and closing geometry, similar behavior as seen in several silver-gold mines in Peru.

Upcoming work activities

The Company also plans to complete work in additional areas such as Zone 3 and the Polymictic Breccia target that the Company believes warrant further follow up (Figure 3).

Recent mapping and sampling results in combination with the historical data, has enabled the Company to identify twenty (20) preliminary targets and drill pad locations (Fig 4). These new targets will be drilled and tested during the upcoming drill campaign.

About Tier One Silver

Tier One Silver is an exploration company focused on creating value for shareholders and stakeholders through the discovery of world-class silver, gold and copper deposits in Peru. The Company is focused on its flagship exploration project, Curibaya. The Company's management and technical teams have a strong track record in raising capital, discovery and monetization of exploration success.

Channel Sampling - Curibaya

Analytical samples were taken from each 0.5-1.0 metre interval of channel floor resulting in approximately 2-5 kg of rock chips material per sample. Collected samples were sent to ALS Lab in Arequipa, Peru for preparation and then to ALS Lima, Peru for analysis. All samples are assayed using 30 g nominal weight fire assay with atomic absorption finish (Au-AA25) and multi-element four acid digestion ICP-AES/ICP-MS method (ME-MS61). Where MS61 results were greater or near 10000 ppm Cu, 10000 ppm Pb or 100 ppm Ag the assay was repeated with ore grade four acid digestion method (Cu, Pb, Ag-OG62). Where OG62 results were greater or near 1500 ppm Ag the assay was repeated with 30 g nominal weight fire assay with gravimetric finish (Ag-GRA21). QA/QC programs for 2021 and 2022 channel samples using internal standard and blank samples; field and lab duplicates indicate good overall accuracy and precision.
