RUMBLE RESOURCES ANNOUNCES ACQUISITION OF INTEREST IN THE WILMAC COPPER-GOLD PROJECT IN SOUTHEASTERN BRITISH COLUMBIA AND CONCURRENT FINANCING

Rumble Resources Inc. has entered into an option agreement, executed on June 10, 2025, whereby it can acquire a 70-per-cent interest, subject to a 2-per-cent net smelter return (NSR) royalty in the Wilmac copper-gold project, which is located in southern-central British Columbia, approximately 10 kilometres west of the currently producing Copper Mountain mine, which currently hosts a proven and probable mineral reserve of 702 million tonnes of 0.24 per cent copper.

The property is interpreted to host potential for the identification of one or more copper-gold alkalic porphyry occurrences similar in age and deposit type to those hosting the Copper Mountain mine. The property comprises two mineral tenures, totalling approximately 2,355 hectares (5,819 acres) in a well-documented and prolific copper-gold porphyry belt.

In order to acquire a 70-per-cent interest in the property, the company must pay $25,000 and issue one million units to the owners at a deemed price of 10 cents per unit upon regulatory approval. Each unit will consist of one common share and one two-year transferable share purchase warrant entitling the owner to purchase an additional common share of the company for 10 cents. The units will be subject to a four-month-and-one-day hold period from issuance. In order to exercise the option, the company must make additional cash payments totalling $305,000 over three years and incur a minimum of $3.99-million in exploration expenditures on the property over five years, including $40,000 by Dec. 31, 2025. The company may purchase half of the 2-per-cent NSR royalty for a one-time payment of $2-million. The company is obligated to make advance NSR payments to the owners of $100,000 per year commencing after the option is exercised.

Private placement

The company further announces that it intends to conduct a non-brokered private placement of up to seven million units at a price of 7.5 cents per unit for proceeds of $525,000. Each unit will consist of one common share and one two-year transferable share purchase warrant entitling the holder to acquire an additional common share for 10 cents. The company intends to offer up to 4.7 million of the units under the listed issuer financing exemption contained in Part 5A of National Instrument 45-106. The common shares comprising the units offered under the listed issuer financing exemption will not be subject to a hold period in accordance with applicable Canadian securities laws. However, the warrants comprising the units and the shares issuable upon the exercise of the warrants will be subject to a 60-day contractual hold period. The company will use proceeds from the private placement for financing the acquisition and exploration on the Wilmac project, an application to have its shares quoted in the United States on the OTC Markets, and for general working capital.

An offering document related to this proposed private placement will be made available under the company's profile on SEDAR+. Prospective investors should read the offering document before making an investment decision. Closing of the offering is subject to a number of conditions, including receipt of all necessary corporate and regulatory approvals. The company may, at its discretion, elect to close the offering in one or more tranches without a minimum offering.
