Vancouver, BC: Metallis Resources Inc. (TSX-V: MTS; OTCQB: MTLFF; FSE: 0CVM) (the “Company” or “Metallis”) is pleased to announce the appointment of Nickolas Dudek, MSc., P.Geo. as Chief Geologist, effective immediately. Mr. Dudek will be responsible for leading Metallis’ field exploration team including the management of daily operations for the Company’s upcoming 2022 drill campaign at the 100%-owned Kirkham Property (the “Property”), situated in the prolific Eskay mining camp in the heart of the Golden Triangle of northwestern British Columbia. The Eskay mining camp is well-known for its diverse metallogeny, highlighted by Pretium’s Brucejack gold mine (recently sold to Newcrest Mining Ltd. for $3.5 billion), the past producing Eskay Creek and Snip gold mines, Tudor Gold’s Goldstorm Au-Cu porphyry deposits and the very large-scale Seabridge Gold KSM-FeCap-Snowfield.

Fiore Aliperti, Metallis’ President and CEO stated, “The management team and I are very excited with the appointment of Nick to lead our exploration team. I’ve spoken at great lengths with Nick over the last few months and hearing his excitement about the Cliff porphyry project cements my feeling that we’ve been incredibly lucky with his addition.” He went on to add “Nick, along with his mentor and Metallis’ Technical Advisor, Charlie Greig, were intimately involved in the discovery of GT Gold’s Saddle deposits over the past few years. To have this knowledge and experience applied to the Kirkham for 2022 is hugely valuable; they are fresh off the success of a discovery that resulted in an acquisition in a little under three years. We hope they can repeat that massive success story here at Metallis”.

Nickolas Dudek graduated with an Honors BSc. in Earth Science from McGill University in 2014 and completed his MSc. from the University of Ottawa in 2017. During his career Mr. Dudek has worked across a diverse set of commodities and has worked on projects both abroad and throughout Canada. Companies he has worked with include Evergold Corp., Bitterroot Resources, Kodiak Copper Corp., and Amarc Resources Ltd. In 2017 Mr. Dudek joined C.J. Greig & Associates Ltd. and was a critical part of GT Gold’s discovery team in the following years, where he logged core, interpreted oriented core and hyperspectral data, managed the logging database and was a primary 3D modeler. His work with Metallis will center around the upcoming 2022 drill program, with a particular focus on developing a geologic model and framework for the Hawilson porphyry complex.
