EAGLE PLAINS AND PACIFIC BAY MINERALS EXECUTE OPTION AGREEMENT FOR HASKINS CRITICAL MINERALS PROJECT, BRITISH COLUMBIA

Further to Eagle Plains Resources Ltd. and Pacific Bay Minerals Corp.'s respective news releases dated April 27, 2026, the parties have entered into an option agreement dated July 7, 2026, pursuant to which Pacific Bay has been granted the exclusive right to acquire up to a 100-per-cent interest in the Eagle Plains' wholly owned Haskins critical metals project.

The 578-hectare road-accessible Haskins project is located 105 kilometres northeast of Dease Lake, B.C., contiguous with Pacific Bay Minerals' Haskins-Reed property to the north. The Haskins project is considered to be highly prospective for carbonate replacement, multielement skarn type, molybdenum-tungsten stockwork porphyry and structurally controlled silver-lead-zinc vein mineralization.

Chuck Downie, president and chief executive officer of Eagle Plains, recently commented: "The recent focus on critical metals development in British Columbia by both the federal and provincial governments underscores the opportunity to develop the Haskins project. The 1,850-hectare footprint of the combined projects makes this an excellent opportunity for Eagle Plains to participate in additional critical metals discoveries."

Under the terms of the agreement, Pacific Bay may acquire a 100-per-cent interest in the Haskins project by completing the following over a four-year period:

• Within 14 days of receipt by Pacific Bay Minerals of the approval of TSX Venture Exchange to the terms of the agreement, pay EPL Eagle Plains 200,000 common shares of Pacific Bay Minerals;
• On or before the first anniversary of the agreement, pay Eagle Plains an additional 300,000 common shares of Pacific Bay Minerals;
• On or before the second anniversary of the agreement:
  • Pay Eagle Plains an additional 750,000 common shares of Pacific Bay Minerals;
  • Pacific Bay Minerals to have completed at least $150,000 in exploration work on the property, with expenditures during the first year of the agreement capped at $50,000;
• On or before the third anniversary of the agreement:
  • Pay Eagle Plains an additional one million common shares of Pacific Bay Minerals;
  • Pacific Bay Minerals to have completed an additional $250,000 in exploration work on the property;
• On or before the fourth anniversary of the agreement:
  • Pay Eagle Plains an additional two million common shares of Pacific Bay Minerals;
  • Pacific Bay Minerals to have completed an additional $500,000 in work on the property.

The Haskins claims are subject to a 2-per-cent net smelter return (NSR) royalty payable by Eagle Plains to a third party, 1 per cent of which may be repurchased by Eagle Plains for $1-million. In the event that Eagle Plains exercises the right to repurchase the 1-per-cent NSR royalty, Pacific Bay Minerals will have the right to purchase that 1 per cent from Eagle Plains for $2-million, leaving a residual 1-per-cent NSR royalty on the Haskins property in favour of the third party. Alternatively, Eagle Plains would agree at any time to assign the 1-per-cent repurchase right to Pacific Bay Minerals for $1-million.

During the term of the agreement:

• Pacific Bay Minerals agrees to retain the services of Terralogic Exploration Inc. to complete the work on the Haskins property;
• Any additional claims acquired by either party within one kilometre of the existing claim boundaries will be included in the agreement.

The terms and conditions of the agreement are subject to the laws of the Province of British Columbia, Canada, and subject to regulatory approval.

About the Haskins property

The Haskins claims adjoin Pacific Bay Minerals' Haskins-Reed property to the north.

Project highlights:

• Host to the Fort Reliance and Joem deposits;
• Excellent geology highly prospective for carbonate replacement, skarn, porphyry and vein mineralization;
• Road accessible;
• Contact metamorphism of the Kechika siltstones and the Atan group limestone and quartzites by the intrusion of the granitic Major Hart pluton caused skarn alteration as well as the presence of molybdenum-tungsten stockwork mineralization at lithological contacts and silver-lead-zinc-bearing veins controlled by crosscutting fault structures.

Geology

The Mount Haskins property lies within the northern extension of the Omineca lithotectonic domain, underlain by the sedimentary Cassiar platform of the Cariboo/Cassiar terrane, which has been intruded by Eocene granitic stocks. Regional structural trends of folding and faulting are dominantly northwest.

Mineralization

There are four deposit types in the Mount Haskins area: carbonate replacement, skarn, porphyry and vein.

About the Haskins-Reed project

The Haskins-Reed property has been explored in several phases by different companies since the late 1940s, including approximately 198 drill holes. The 100-per-cent-owned land package, which includes six Crown grant claims, is host to multiple mineral prospects:

• B zone (Minfile 104P 038): Skarn-hosted semi-massive to massive sulphide lenses, with silver- and gold-bearing pyrrhotite-sphalerite-chalcopyrite-galena mineralization, are hosted by metasomatized carbonate rocks. Mineralization occurs as three lenses with an aggregate strike length of 308 metres, an average true width of eight metres and an average dip of minus 40 degrees with strong vertical continuity.
• Mount Reed molybdenum-tungsten prospect (Minfile 104P 043): Molybdenum and tungsten mineralization is hosted by peripheral contact metamorphic exoskarn developed in carbonate-rich metasedimentary rocks of the Atan group. These rocks surround a small Eocene-age porphyritic granitic stock, with additional porphyry-style mineralization found within the intrusion itself. Historical drilling returned values of 2.01 per cent WO3 (tungsten trioxide) over 3.3 metres, 0.37 per cent WO3 over 5.18 metres and 0.17 per cent WO3 over 54.8 metres.
• Joe Reed vein prospect (Minfile 104P 021): Silver-rich sphalerite-galena-pyrite shear-hosted vein mineralization occurs within a persistent northerly trending fault zone that cuts through Lower Cambrian Atan group quartzite, limestone and dolomite. A steep, westerly dipping quartz vein averaging 1.5 metres wide can be traced along strike for 170 metres.
• Brett zone (Minfile 104P 136): A skarn-hosted massive sulphide zone with silver- and gold-bearing pyrrhotite-sphalerite-chalcopyrite-galena mineralization is hosted by metasomatized metasedimentary rocks immediately northwest of the Mount Reed stock.
• Dako and Cobra zones (Minfile 104P 139, 058): Disseminated to locally massive pyrrhotite-rich base metal garnet skarn mineralization is hosted at a limestone-argillite contact within metasedimentary rocks altered to calc-silicate hornfels and skarns. Mineralization consists of pyrrhotite, sphalerite, and minor galena and chalcopyrite. The local geology is very similar to the Brett zone.
• Meteor zone (Minfile 104P 137): This polymetallic gold-silver-lead-zinc skarn-hosted prospect was discovered during the 2010 trenching program while evaluating coincident soil geochemical and aeromagnetic anomalies in the north-central portion of the property. It has been traced over 555 metres of strike length, with widths ranging from four to 16 metres, and remains open along strike and downdip. 2010 excavator trenching returned intervals such as 24.70 metres grading 0.292 gram per tonne gold, 57.11 g/t silver, 1.21 per cent lead and 3.67 per cent zinc (trench No. 4), with a nearby grab sample returning 0.680 g/t Au, 176 g/t Ag, 0.75 per cent Pb and 12.30 per cent Zn. Drilling in 2011 intersected 17.5 metres grading 88.35 g/t Ag, 1.11 per cent Pb and 3.39 per cent Zn.

Since acquiring an option on the Haskins-Reed property in 2008, Pacific Bay has carried out substantial additional exploration, including drilling campaigns in 2011 and 2018, a full-property airborne geophysical survey, trenching, geochemical surveys, mapping, and a digital compilation of most of the project's historic maps, drill logs and other exploration data.

Some of the above results were taken directly from Minfile descriptions and assessment reports (ARIS) filed with the British Columbia government. Management cautions that historical results were collected and reported by past operators and have not been verified nor confirmed by a qualified person but form a basis for continuing work on the subject properties.
