Tier One Silver Reports Channel Sampling Results from the Magdalena Target at Hurricane

VANCOUVER, November 15, 2022 - Tier One Silver Inc. (TSXV:TSLV)(OTCQB:TSLVF) ("Tier One" or the "Company") is pleased to report rock and channel sampling results from the Magdalena target area on the Hurricane project in southern Peru (Figure 1). Highlights from the program include 1 metre (m) of 852.5 g/t silver (Ag), 1.54% copper (Cu), 0.34% lead (Pb) and 0.23% zinc (Zn), 1 m of 522.5 g/t Ag, 1.15% Cu, 0.18% Pb and 0.18% Zn and 2 m of 232.5 g/t Ag, 0.37% Cu, 1.06% Pb and 1.78% Zn. These results have extended the mineralization at Magdalena by 500 m, where a total of 4 kilometres (km) of vein corridors have been recognized to date, and where numerous underground historical workings have been observed. Table 1 summarizes highlights from the channel samples taken during the program.

A Message from Christian Rios, SVP, Exploration:
"It's exciting to see the Magdalena target significantly expand after just 15 days of field work. Mineralization is present across horizontal and vertical extents with more than 150 m in vertical exposure and two levels of historical underground workings. Additionally, we are seeing anomalies that are consistent with an intrusive related system and the mineralization remains open in all directions, making this area a strong exploration priority of the 13 targets in the Hurricane district."

Magdalena Epithermal Structures:
Silver-rich epithermal vein - fault structures have been mapped over an area of approximately 2 km by 2 km with approximately 200 m of vertical exposure. Recent field work consisted of mapping, rock and channel sampling with the goal of extending the strike length of the mineralized structures and getting a better understanding of the grade distribution through infill channel sampling of previously sampled veins (Figures 1 - 2 & Tables 1 - 2).

There are two primary mineralized structures, each greater than 1 km in length, as well as numerous splays and smaller structures in the Magdalena target area (Figure 1). The primary mineralized structures and splays have a combined strike length greater than 4 km and an average width of 1 m - 2 m with local vein widths up to 7 m wide. All mineralized structures remain open along strike and with nearly 60% of the target area under cover there is significant potential to discover extensions of and/or additional mineralized structures.

The mineralized structures were exploited historically via numerous underground mine workings and both recent and historic sampling of these mine dumps reveal significant high-grade silver and copper values (see Table 2 and Dec. 9, 2021 news release). Highlights of the rock sample results from the historic mine dumps include: 861 g/t Ag, 1.11% Cu, 20.00% Pb, 11.35% Zn and 0.20% tungsten (W), 1,580 g/t Ag and 0.57% Cu, and 762 g/t Ag and 2.31% Cu. These results illustrate the continuity of mineralization at depth and the high silver and copper values provide examples of the grades that the mineralized system is capable of producing.

Individual channel and rock samples reported elevated tungsten and anomalous rhenium and scandium values that are consistent with an intrusive related mineralized system. Of the 48 rock samples and 44 channel samples, 11% returned tungsten values above 0.1%, with one sample reporting 0.9% W. In addition, dioritic porphyry dykes have been mapped on surface that may be related to elevated tungsten values.

The next phase of exploration at Magdalena will focus on additional field work that includes soil sampling, mapping, trenching and a magnetics IP geophysical survey to evaluate the potential of these structures and the possible magmatic source.

Channel Sampling:
Analytical samples were taken from each 0.1 m - 2.15-m interval of channel floor resulting in approximately 2-4 kg of rock chips material per sample. Collected samples were sent to ALS Lab in Arequipa, Peru for preparation and then to Lima, Peru for analysis. All samples are assayed for gold, platinum and palladium using 30 g nominal weight fire assay with ICP-AES finish method (PGM-ICP27) and for multi-element using four acid digest ICP-AES/ICP-MS method (ME-MS61). Where MS61 results were greater or near 10,000 ppm Cu, 10,000 ppm Pb, 10,000 ppm Zn or 100 ppm Ag, the assays were repeated with ore grade four acid digest method (Cu, Pb, Zn, Ag-OG62). Where OG62 results were greater or near 1,500 ppm Ag, the assays were repeated with 30 g nominal weight fire assay with gravimetric finish (Ag-GRA21). QA/QC programs for 2022 channel samples at Hurricane using internal and lab standard and blank samples, and field and lab duplicates, indicate good overall accuracy and precision.
