Pacific Bay Announces LOI to Option Atlin Goldfields

Pacific Bay Announces Letter of Intent to Option Atlin Goldfields Property in BC, and $500,000 Non-Brokered Financing

Vancouver, British Columbia, March 24, 2022.David H. Brett, President and CEO, Pacific Bay Minerals Ltd. (TSX Venture: PBM, “Pacific Bay” or the “Company”) reports that Pacific Bay has signed a Letter Agreement (the “Agreement”) with Brixton Metals Corp. (“Brixton”) to acquire an option to purchase up to a 100% interest in the Atlin Goldfields Project (the “Property”), located in Northwest British Columbia. The Agreement is subject to the completion of a definitive option agreement, the completion by PBM of a $500,000 financing, and the approval of the TSX Venture Exchange.Atlin Goldfield Highlights:

• Underexplored, district-scale gold property with 59,154 hectares of mineral tenures.
• Prospective for high grade orogenic gold deposit systems including the Yellowjacket high grade gold deposit.
• 200 ton-per-day mining permit (Yellowjacket Mine) and exploration permits already in place
• Top-tier mining jurisdiction

“Atlin Goldfields is located in a district known for its prolific placer gold found in the majority of its drainages, which include Spruce Creek, home of the largest gold nugget in British Columbia,” said Pacific Bay VP of Exploration Sebastien Ah Fat, P.Geo. “Historical drilling has found that the source of the placer gold is in close proximity to the creek drainages. We believe Atlin Goldfields has the potential to host extensive mesothermal gold mineralization within the shear zone corridors identified by past geochemical and geophysical surveys. We are looking forward to extensively exploring this property.”“Atlin is one of BC’s most famous gold districts,” said Pacific Bay President & CEO David Brett. “Brixton has done an excellent job of consolidating and exploring the Property, including compiling a vast database that we look forward to leveraging.”Atlin Goldfields Property Overview:The Property is situated in Northwest British Columbia, east of the town of Atlin, consisting of a district scale 59,154 hectares of mineral tenures in addition to a Mines Act permit over the Yellowjacket zone authorizing a for 200 tons per day operation. The surrounding infrastructure offers excellent access to the project through its local airstrip, year-round Provincially maintained highway between the town of Atlin and the Property, and gravel roads to the majority of showings on the claim. The property is approximately 175 km by government-maintained highway southeast of Whitehorse, Yukon, which offers daily flights from Vancouver, BC and Calgary, AB; and 249 km east of the Skagway Port.Figure 01: Atlin Goldfield’s location in Northwest BC, highlights the mineral tenures and surrounding claims.The Atlin gold camp is the second largest gold placer producer in British Columbia with over 600,000 troy ounces of gold produced between 1898 and 1945, predominantly in Pine, Spruce, and Otter creeks. For decades, the source of the placer gold was not fully understood. In the late 1980’s, Homestake Mineral Developments, conducted ground magnetic geophysical surveys over the Yellowjacket zone that outlined a possible fault zone associated with the boundary of the Cache Creek ultramafic complex, which was located directly underneath the placer operations. Subsequently, diamond drilling discovered an orogenic sheared hosted mesothermal gold zone. This type of mineralization often displays nugget-like gold within quartz-filled shear zones similar to mines such as Bralorne, Cassiar, and Sheep Creek in British Columbia and the Motherlode mine in California. Since then, several exploration companies have explored the area, particularly the Yellowjacket zone, where extensive drilling has taken place. Brixton initially acquired the property in 2016 and over the years consolidated the mineral tenures into one land package while also completing over 5,000 surface and soil samples, property wide high resolution airborne magnetic survey, and 1,599 metres of diamond drilling in 22 holes. Overall, the Property hosts 24 mineral occurrences of which 17 are associated with gold.Historical drilling at Yellowjacket totals 25,767 metres distributed over 319 holes with several holes yielding excellent gold results. Select historic drill holes are shown in the table below.

Table 02: Summary of historical mineral resource estimate at the Yellowjacket Mine from 2010.A qualified person representing Pacific Bay has not done sufficient work to classify the historic estimate as current mineral resources or mineral reserves. As such the issuer, Pacific Bay, is not treating this historical estimate as current mineral resources or mineral reserves.Figure 02: Yellowjacket 3D model displaying grade gold shells.Pacific Bay’s Vision for Atlin Goldfields:From the Company’s VP Operations, Antonio Vespa, “The Atlin Goldfields Option is the culmination of a lengthy search for a transformational asset to add to Pacific Bay’s portfolio. The significant exploration potential at Atlin provides us with the unique opportunity to build shareholder value, and a notable resource upon which we can further enhance the prospects of the Company towards being a gold producer in the medium term. There is considerable bullish market sentiment around gold, and we believe the timing is right to take on this robust project.”Figure 03: 4 Designated Exploration Areas – 4 Brownfield Areas (highlighted in yellow), 5 Greenfield Areas (highlighted in green).Terms of the Agreement:Under the terms of the Letter Agreement, Pacific Bay may acquire up to a 100% interest in the Atlin Goldfields project, by completing the following:

1. Pacific Bay can earn a 51% interest in the Property by completing $3,500,000 in Exploration Expenditures, paying $1,725,000 cash, and issuing 5,000,000 Pacific Bay Shares, on or before the 4th anniversary of the closing of the Agreement.
2. If the 51% interest earn-in has been completed, Pacific Bay may earn an additional 49% interest in the Property by completing an additional $3,500,000 in Exploration Expenditures, paying $1,500,000 cash, and issuing 5,000,000 Pacific Bay Shares, on or before the 7th anniversary of the closing of the Agreement.

If Pacific Bay exercises the 51% earn-in and elects to not exercise the additional 49% earn-in, Pacific Bay and Brixton will enter into a joint venture whereby the interest in the property will revert to 49% in favor of Pacific Bay and 51% in favor of Brixton, with each party then participating in programs and budgets according to their pro-rata interests.If Pacific Bay completes the option and acquires 100% of the Property, Brixton will retain at 2% Net Smelter Return Royalty (NSR), with 1% of the NSR purchasable at any time by Pacific Bay for $2,500,000. The Property is subject to a number of additional underlying royalties in favour of other vendors.All values in Canadian dollars.
