Bunker Hill enters deal to acquire Ranger-Page property

Mr. Sam Ash reports BUNKER HILL ANNOUNCES AGREEMENT TO ACQUIRE THE HISTORIC RANGER-PAGE SILVER- LEAD-ZINC MINES TO EXPAND EXPLORATION POTENTIAL IN THE SILVER VALLEY OF IDAHO Bunker Hill Mining Corp.'s wholly owned subsidiary, Silver Valley Metals Corp., has entered into an asset purchase agreement with Silver Dollar Resources (Idaho) Inc., a subsidiary of Silver Dollar Resources Inc., to acquire the Ranger-Page property which includes, six past-producing underground high-grade silver-lead-zinc mines located immediately adjacent to and to the west of the Bunker Hill mine in the prolific Silver Valley mining district of Idaho, United States. The acquisition is expected to consolidate one of the most historically productive areas of the Coeur d'Alene mining district under Bunker Hill's control, increasing the size of the company's mineral claim package by approximately 1,205 acres (4.8 square kilometres). The asset acquisition will also include an extensive historical geological database. Contingent on exploration success, this could extend operational life at Bunker Hill, maximize economies of scale and unlock additional local synergies. Strategic highlights Consolidated land position: The acquisition, once complete, will unite the Ranger-Page Mines and Bunker Hill mine into a contiguous land package exceeding 6,200 acres (25 square kilometres), creating one of the largest and most prospective holdings in the Silver Valley. Exploration upside: Historical drilling and production data from the Ranger-Page Mines indicate high-grade silver-lead-zinc mineralization remains open at depth and along strike (drill hole 34-142_NE: eight feet at 9.41 ounces per tonne Ag (silver), 13.4 per cent Pb (lead), 3.1 per cent Zn (zinc) -- see March 11, 2025, release). Infrastructure synergies: The Ranger-Page Mines' existing underground workings and surface access points could provide additional flexibility for future mine planning, ventilation and exploration access to deeper levels of the Bunker Hill mine system. Complementary to restart plan: The acquisition, once complete, will align with Bunker Hill's continuing restart of operations at the Bunker Hill mine, targeted for H1 2026, and will enhance the company's upside optionality for future resource expansion and mill feed sources. Community benefits: This has the potential to create more local employment opportunities within the Silver Valley and stimulate procurement from regional suppliers in ways that benefit the local communities. Sam Ash, president and chief executive officer of Bunker Hill Mining, stated: "The addition of the Ranger-Page Mines will be another key step in our vision to re-establish Bunker Hill as a leading producer in the Silver Valley. The Ranger-Page mine infrastructure and mineralized zones are geologically continuous with the Bunker Hill system, offering immediate synergies for exploration, development and potential future production." Highlights of the Ranger-Page Mines include: Silver, plus high-grade lead and zinc: High-grade historic production, the Ranger-Page Mines complex was a top 10 producer in the Silver Valley, estimated to have produced 1.1 billion pounds of zinc and lead mined and 14.6 million ounces of silver. Six historic mines: Two historic mines produced to depths of 2,644 feet (805.9 m) and 1,200 feet (365.8 m), respectively. Four of the six mines were less than 200 feet (61 m) in depth, leaving significant open-ended exploration potential at depth. Historical remaining mine resource of 218,000 tons grading 87.4 g/t silver, 10.34 per cent zinc and 5.22 per cent lead. The estimated results were constrained by the depth of the Page mine shaft. Mining ceased during a difficult period of historically low metal prices, compounded by a fire which destroyed the mill. No systematic exploration work was ever conducted to expand these estimated resources at depth. Note that a qualified person has not reviewed the historical data and has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserve. It is not known what parameters were used to calculate the historic mineral resource. The historic resource is not being treated by the company as a Canadian National Instrument 43-101-compliant resource and is listed here for reference only. Underexplored property package: In particular, the area between the Ranger-Page Mines and Bunker Hill Mines -- the Silver Gap, which contains similar host geology and structural framework. Due to the fragmented historical ownership, this highly prospective approximately four km trend remains unexplored. Recent work by Silver Dollar identified numerous near-surface exploration targets along structures hosting historic mines on the Ranger-Page Mines. Maiden drilling on the Wyoming target intercepted potentially underground mineable silver-lead-zinc mineralization in all three holes, including 162 g/t Ag, 15.5 per cent Pb and 4.1 per cent Zn over 10 ft (3.04 m) (drilled thickness, true thickness unknown) -- see March 11, 2025, release. Patented lode claims: Ownership of surface and mineral rights. Transaction summary Under the terms of the agreement, Bunker Hill will acquire 100 per cent of Silver Dollar's interest in the Ranger-Page Mines for total consideration of $2.4-million (U.S.), comprising 23,333,334 Bunker Hill common shares (the payment shares), subject to the below contractual escrow. The completion of the acquisition will be subject to the approval of the TSX Venture Exchange. The payment shares will be subject to a four-month-and-one-day hold period from the date of issuance. Conference call and webcast Bunker Hill will host a webinar on Oct. 30, 2025, at 8 a.m. PT/11 a.m. ET. Participants may join the webinar by registering on-line. A replay of this webinar will be available on Bunker Hill's website. About Bunker Hill Mining Corp.
