Myriad Uranium Announces Approval of Plan of Operations Which Provides Clearance for 222 Boreholes at Copper Mountain

Vancouver, British Columbia--(Newsfile Corp. - October 9, 2025) - Myriad Uranium Corp. (CSE: M) (OTCQB: MYRUF) (FSE: C3Q) ("Myriad" or the "Company") is pleased to announce that the Bureau of Land Management has approved a Plan of Operations for the Company's Copper Mountain Project Area. The Plan of Operations was submitted as a technical amendment to the existing Drilling Notification in place for the 2024 Drilling Season and allows for an expanded footprint of activities up to 222 boreholes across the Project, including high-priority targets such as Lucky Cliff which has exciting historical intercepts. Currently, under the existing Drilling Notification with the State of Wyoming, Myriad is bonded for 70 of those holes. The Drilling Notification can be updated to bond the remaining holes in subsequent phases. This is a major step forward for the Project and will enable Myriad to demonstrate the broader potential of the Copper Mountain District beyond the Canning Deposit.

Myriad CEO Thomas Lamb commented: "Having verified much of the original drilling conducted by Union Pacific at Canning, we now have the permit we need to continue drilling not only at Canning, but also at other target areas to confirm the entire Project's vast potential."

Plan of Operations

The approved Plan of Operations (the "Plan") allows for the drilling of up to 222 holes at numerous targets across the Copper Mountain Project Area. Currently, under the existing Drilling Notification with the State of Wyoming, Myriad is bonded for 70 of those holes, 50 of which were carried over from Canning during the previous drilling season in 2024. The Plan will be amended and additional drilling bonded on an ongoing basis as the Company's exploration strategy for Copper Mountain progresses. The areas currently covered by the Plan include Mint, Arrowhead, Lucky Cliff and Gem, as well as additional drilling at Canning. The Company's strategy is to continue to confirm the presence of historically identified mineralization while also demonstrating the broader potential of Copper Mountain to host many more large deposits, as was discussed in the Company's October 1, 2025 news release which can be viewed here. Union Pacific had plans to advance development at the seven historical resource estimate areas and continue exploration at 15 other target areas with known mineralization during the 1980s, but these plans were cut short by the Three Mile Island incident in 1979, which had a major negative impact on the uranium sector and the commodity price, particularly in the USA. In addition to the targets currently allowed for in the Plan, several others such as Hesitation, Fuller, Knob and Cedar Ridge may be considered in the near-term for drilling, pending amendments to the approved Plan.
