Tier One Silver Obtains Community Agreement for Copper-Nickel Prospects

at Hurricane Silver Project

Vancouver, Canada – May 19, 2022 – Tier One Silver Inc. (TSXV: TSLV, OTCQB: TSLVF) (“Tier One” or the

“Company”) is pleased to announce that it has gained additional social access at the Hurricane Silver

project, located approximately 65 kilometres (km) north of the city of Cusco. A social agreement has

been signed with the Hualla community, which will allow for exploration of the Ñañohuayco, San

Cipriano and Morro Culispata copper -nickel-platinum-palladium-silver prospects (Figure 1). The

agreement is valid for two years and allows the Company to conduct surface work as well as drilling

once a drill permit has been obtained from the Peruvian Ministry of Energy and Mines. Historical

work at the Ñañohuayco and San Cipriano prospects included surface sampling, ground -based

geophysical surveys and initial drill tests by the previous operator from 2009 – 2010. The 10-hole

1,061 metre (m) historical drill program at Ñañohuayco included 14 m of 2.59% copper, 0.62%

nickel, 311 g/t cobalt, 0.3 g/t platinum and 0.55 g/t palladium (Figures 2 – 3).

A Message from Peter Dembicki, President, CEO & Director:

“Access to Ñañohuayco allows us to begin exploration at a high priority target at our Hurricane Silver

project. The historical intercepts from the target demonstrate significant grade, and there has been

minimal exploration, so we look forward to following up. Over the coming months we will work to

further define targets at Hurricane Silver as we get ready to resume drilling at Curibaya.”

Geological and Historical Exploration Overview:

Geologically, the copper-nickel-platinum-palladium magmatic sulphide mineralization observed at

the Hurricane Silver project is associated with Permo -Triassic rifting and the emplacement of

ultramafic intrusives within the Pisco-Albancay deflection of southern Peru. The district was initially

assembled based on the results of a high -quality stream sediment survey underta ken in 2007 –

2009, when anomalous copper, nickel, platinum and palladium drainage values were identified

(Figures 4 – 5).

The northern region of the Hurricane Silver district, where social access has been obtained, is

characterized by the Ñañohuayco, San Cipriano and Morro Culispata copper -nickel-platinum-

palladium occurrences. Limited surface work has been conducted in these areas, with rock chip and

channel sampling demonstrating the high -grade potential of the mineralized systems. Highlights

from historical channel sampling at Ñañohuayco include 14 m of 4.69% copper and 0.51% nickel,

18 m of 3.28% copper and 0.50% nickel and 10 m of 3.35% copper and 0.61% nickel (Figure 6).

Highlights from channel sampling at Morro Culispata include 8 m of 2.17% copper and 0.3% nickel

and 2 m of 3.74% copper and 0. 47% nickel (Figure 6). Table 1 below presents highlights from

historical channel sampling.

The first-pass drill programs at Ñañohuayco and San Cipriano totaled 10 drill holes over 1,061 m

and 11 holes over 1,722 m, respectively. These historical drill programs targeted flat lying ultramafic

sills with highlighted results listed below in Table s 2 and 3. Importantly, at both Ñañohuayco and

San Cipriano there are untested chargeability and conductivity anomalies that the Company’s

technical team believe s have the potential to correspond to copper -nickel-platinum-palladium

magmatic sulphide style of mineralization.

Exploration Plan Phase 1:

The Company will look to expand on the positive historical exploration work at the Ñañohuayco,

San Cipriano and Morro Culispata prospects and to evaluate new target areas through geological

mapping, soil sampling, rock and channel sampling and additional ground -based geophysical

surveys. The Company’s goal is to identify the ultramafic source areas to the mineralized sub -

horizontal sills that have been identified historically.
