Pacific Bay Commences Drilling at Atlin Goldfields Property

For Immediate Release. Vancouver, British Columbia, September 7, 2022. Mr. Antonio Vespa, President & CEO,

Pacific Bay Minerals Ltd. (TSX Venture: PBM, “Pacific Bay” or the “Company”) reports that diamond drilling has

commenced at the Company’s Atlin Goldfields Project (“the Property”) near the town of Atlin in northern British

Columbia. The Company has contracted Diamondhead Drilling to complete a series of drill holes targeting the

Property’s high grade Yellowjacket shear/vein system. Pacific Bay holds an option to acquire up to a 100%

interest in the Property from Brixton Metals Corporation.

“We’re excited to kick off our first drill campaign at Atlin” said Pacific Bay CEO, Antonio Vespa. ”Our initial

objective is to confirm and expand the high grade gold mineralization at Yellowjacket.”

The initial four drill holes proposed for the fall 2022 diamond drill program are aimed at confirming historical

results and expanding upon the Yellowjacket mineralization. The Yellowjacket Zone consists of orogenic gold

mineralization confined along the distinctive Pine Creek Fault system and is loca ted immediately above the

significant historic “Discovery” gold rush placer deposits.

The Yellowjacket occurrence includes individual, mineralized quartz veins, that are hosted within pre -existing

structures, as well as zones of mineralized vein arrays. Listwanitic altered ultramafic rocks are consistently

associated with the gold veins and vein arrays , with the gold most commonly hosted in gabbro, diabase, basalt

and andesite (brittle, crackle fractured rocks) in fault contact with ultramafic rocks. Free gold mineralization

occurs as scatted coarse native gold grain s associated with minor pyrite, chromite and mariposite (Morton, J .,

Yellowjacket has a BC Ministry of Mines Small Mine Permit (75,000 tonnes per year) in place with the operation

currently under care and maintenance.
