Canada One Mining to acquire Copper Dome North

Mr. Peter Berdusco reports CANADA ONE ACQUIRES 4,836 HA COPPER-GOLD PROPERTY ADJACENT TO COPPER MOUNTAIN MINE Canada One Mining Corp. has agreed to acquire a 4,836-hectare copper-gold property contiguous to the northwest of Hudbay Minerals' Copper Mountain mine, to be known as Copper Dome North. Under the property purchase agreement, dated Oct. 6, 2025, the company will acquire a 100-per-cent interest in the property from an arm's-length vendor. The acquisition increases the company's flagship Copper Dome project size by approximately 60 per cent to 12,833 hectares (from 7,997 hectares). Peter Berdusco, president and chief executive officer, commented: "Though outside the formal Copper Dome footprint, the property's proximity to Copper Mountain and its continuity within the district's geologic setting warrant the designation Copper Dome North. In addition, the property is adjacent to our 100-per-cent-owned Goldrop, an underexplored, historical small-scale producer of high-grade gold and silver. Together, these factors make the acquisition compelling and well suited to a systematic exploration program." Copper Dome North acquisition terms The agreement provides for the 100-per-cent acquisition of the property with no net smelter return (NSR) royalty in consideration for 250,000 common shares of the company, valuing the transaction at $12,500 based on a deemed price of five cents per share. The consideration shares will be subject to a statutory hold period of four months and one day from the closing of the acquisition. Completion of the acquisition is subject to customary closing conditions and acceptance by the TSX Venture Exchange. The acquisition does not involve any non-arm's-length parties (as defined in exchange policies). The company will not devote the majority of its working capital or resources to the development of Copper Dome North. The primary focus of the company remains the exploration and future drilling at Copper Dome. As a result, the acquisition does not constitute a fundamental acquisition for the company within the policies of the exchange. No finders' fees or commissions are payable in connection with the acquisition. About Copper Dome Copper Dome is located in the lower Quesnel trough porphyry belt, one of British Columbia's most prolific mining districts. It directly adjoins Hudbay Minerals Inc.'s producing Copper Mountain mine to the north, which hosts proven and probable reserves of 702 million tonnes grading 0.24 per cent copper, 0.09 gram per tonne gold and 0.72 gram per tonne silver. Multiple mineralized zones have been identified across the property, with historical drilling confirming high-grade copper associated with northeast-trending structures similar to those hosting mineralization at Copper Mountain. The project benefits from excellent infrastructure, enabling year-round access, cost-efficient exploration and a stable, low-risk jurisdiction. Historical work completed Geophysics: 51 kilometres of induced polarization (IP); airborne magnetic and electromagnetic (EM) coverage over approximately 50 per cent of the property; Sampling: 2,253 soil samples and 378 rock samples collected; Drilling: more than 8,900 metres of diamond drilling; Trenching: over one kilometre excavated. With a five-year drill permit in place, the company is focused on advancing the project toward drill-ready target definition. About Canada One Mining Corp.
