VANCOUVER, BC / ACCESSWIRE / June 9, 2021 / Tier One Silver Inc. (TSXV:TSLV) ("Tier One" or the "Company") is pleased to announce that common shares of the Company will commence trading today on the TSX Venture Exchange under the symbol TSLV. The Company is also announcing that it has received its Peruvian Inicio de Actividades ("Start of Activities") permit, which provides authorization for the Company to commence its inaugural drill program at the wholly[1] owned Curibaya silver-gold project in southern Peru. With this authorization, the Company has finalized the permitting process with the MINEM, the Peruvian mining regulator.

Tier One has signed a contract with G&G Drilling and preparations are underway for the upcoming drill program. This includes expanding the on-site camp, transporting equipment and building drill pads. Water is also being transported from a local authorized EPS water supply company to the Curibaya project. The Company anticipates drilling at Curibaya will commence this month and continue for several weeks.

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

"We are pleased to begin trading on the TSXV, an internationally recognized stock exchange, along with many other successful mining companies. Having a fully permitted exploration program allows us to commence drilling this month at the highly prospective targets we've identified at our flagship Curibaya project."

"Trading on the OTCQB will allow us to expand our audience and provide better access for our U.S. shareholders. We look forward to an exciting year filled with numerous catalysts as we advance our portfolio of projects."

A Message from David Smithson, SVP, Exploration:

"It has been incredible to watch Curibaya grow from a stream sediment anomaly in 2016 to a newly recognized Paleocene-aged epithermal system -the first of its kind in this part of Peru, to our knowledge, defined by wide-spread, high-grade veins with up to 298 kg/t Ag and 934 g/t Au sampled. Our geophysical data confirms that there is the potential for a mineralization window that extends 750 m below the high-grade footprint on surface, with an overall dimension of 1.4 km x 1.8 km x 750 m. We are excited to put the very first holes into this large-scale opportunity and realize its potential as a world-class discovery."

OTCQB Application:

The Company is applying to have its common shares posted for trading on the OTCQB Venture Market (the "OTCQB"), a United States trading platform that is operated by the OTC Markets Group in New York. The posting of the Company's shares on the OTCQB remains subject to having a Form 211 cleared by FINRA, satisfying OTCQB eligibility standards and the approval of the OTCQB Markets Group. The Company will provide further information once its common shares commence trading on the OTCQB.

The OTCQB market is a premiere marketplace for early-stage and developing companies that are committed to providing a high-quality trading and information experience for U.S. investors. Investors can find real-time level 2 quotes and market information for OTCQB-listed companies on the OTC Markets website.

Tier One believes that trading on the OTCQB will increase its visibility within the U.S. capital markets. The Company will also continue to trade on the TSXV under its symbol TSLV.
