VANCOUVER, BC / ACCESSWIRE / November 18, 2021 / Tier One Silver (TSXV:TSLV, OTCQB:TSLVF) ("Tier One" or the "Company") is pleased to report results from drill holes 4 - 6 at the Curibaya project in southern Peru (Figure 1). Drill hole 6 targeted the Madre structure, which has emerged as the primary target structure on the project to-date, and intersected 1 metre (m) of 1,480.5 g/t silver equivalent (AgEq) within a broader interval of 3.5 m of 442.5 g/t AgEq at a drill depth of 107.5 m to 111 m (Figure 2). Tier One's technical team believes the result from hole 6 demonstrates the high-grade potential along the 1.4-kilometre (km) long Madre structure, as defined by mapping and remote sensing data. Currently, there are results from three drill holes along the Madre structure pending, including a first drill hole into the diatreme dome complex that the technical team believes is the potential source for precious metal mineralization across the property (Figure 1).
A Message from Peter Dembicki, President, CEO & Director:
"Hole 6 is the first plus-kilogram intercept at Curibaya on a feeder vein that may host the extensive high-grade silver on surface, which gives us the confidence that we are in the infancy of a new silver discovery. Drilling along structures that have yielded positive channel sample results is proving to be a sound strategy as the Company looks to realize the vast potential of the property indicated through high-grade silver mineralization on surface."
Drill Holes 4 - 5:
Drill holes 4 and 5 targeted the Sama and Sambalay structures, respectively, and both drill holes encountered significant silver mineralization in multiple parallel structures. Hole 5 is the second drill hole to test the 900 m long Sambalay structural corridor and intersected 1 m of 579.6 g/t AgEq, 0.5 m of 266.8 g/t AgEq, 1 m of 88.1 g/t AgEq and 11 m of 37.8 g/t AgEq (Figure 3). Hole 4 was the first drill hole to test the Sama structure and intersected 1 m of 211.6 g/t AgEq within a broader interval of 3 m of 96.4 g/t AgEq, 1m of 137.5 g/t AgEq, 1 m of 99.6 g/t AgEq and 0.5 m of 172.8 g/t AgEq (Figure 4). A summary of the results from drill holes 4 - 6 are provided below in Table 1.

Significance of Results and Program Update:
The results from drill holes 4 - 6 demonstrate that significant precious metal mineralization extends to depth below mineralization encountered in surface channel samples. In addition, hole 6 was the first drill hole to test the margin of the high chargeability anomaly that, in part, defines the Madre structural corridor. The positive correlation between high-grade mineralization in drill hole 6 and the margins of the chargeability anomaly further strengthens the Company's targeting efforts at depth.
To date, the Company has drilled a total of 12 holes into four of the five precious metal feeder structures for a total of 4,473 m, with results pending for six holes. The Company plans to drill an additional 1,000 m in three holes along the Madre structure, prior to a pause in drilling for the rainy season beginning in mid-December. The Company expects to resume drilling at Curibaya at the end of Q1 2022. In addition, a drill permit expansion is in progress to include the Cambaya structures, to the northeast of current drilling, which the Company plans to drill test in 2022.
A Message from Dave Smithson, SVP of Exploration:
"The positive results from hole 6 represent a major advancement in our understanding of the controls on high-grade mineralization within the project. The combination of alteration vectoring, targeting the margins of high chargeability anomalies and surface geochemical channel sampling is paying dividends with the drill. These results continue to support our view that Curibaya has the potential for a major discovery."

Curibaya Drilling
Analytical samples were taken by sawing HQ or NQ diameter core into equal halves on site and sent one of the halves to ALS Lab in Arequipa, Peru for preparation and then to 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 digest ICP-AES/ICP-MS method (ME-MS61). Where MS61 results were greater or near 10,000 ppm Cu, 10,000 ppm Pb or 100 ppm Ag the assay were repeated with ore grade four acid digest method (Cu, Pb, Ag-OG62). Where OG62 results were greater or near 1,500 ppm Ag the assay were repeated with 30 g.
QA/QC programs for 2021 core samples using company and lab duplicates, standards and blanks indicate good accuracy and precision in a large majority of standards assayed.
Silver equivalent grades (AgEq) were calculated using silver price of US$18/oz, gold price of US$1,300/oz, zinc price of US$1.25/lb, and lead price of US$1.00/lb. Metallurgical recoveries were not applied to the silver equivalent calculation.
Intercepts were calculated with no less than 5 m of >= 25 g/t AgEq with maximum allowed consecutive dilution of 6 m.
True widths of mineralization are unknown based on current geometric understanding of the mineralized intervals.
