Vancouver, British Columbia--(Newsfile Corp. - April 19, 2024) - Myriad Uranium Corp. (CSE: M) (OTCQB: MYRUF) (FSE: C3Q) ("Myriad" or the "Company") is pleased to announce that its earn-in partner Rush Rare Metals Corp. ("Rush"), again guided by proprietary data, has acquired the historic Bonanza and Kermac/Day uranium mines at Copper Mountain (See Figure 1 below). Various proprietary documents in Myriad's possession indicate that the Bonanza Mine produced around 780,000 lbs from 30,000 tons of ore at a grade of 1.3% eU3O8, while at the Day Mine, 1,152 tons of ore were mined at grades of between 0.12% and 0.56% eU3O8 in the early 1960's (see Figure 2 below).

"Bonanza-Kermac" aggregates 280 acres, and its acquisition increases the area subject to Myriad's 75% earnable interest under the property option agreement between Myriad and Rush from 3,605 acres to 3,886 acres.

Myriad's CEO Thomas Lamb commented, "We continue to add highly prospective acreage at Copper Mountain."

Production during the late 1950's and 1960's from the Bonanza Mine Area came from siltstones of the Wind River Formation overlying the pre-Cambrian basement granitic rocks. Mineralization in these areas formed by basinward migration of uranium in channel sediments with precipitation occurring at roll-front boundaries or fault/hydrocarbon redox areas. The deposit lies downstream of the old Little Mo (Arrowhead) Mine which was the first area of production (around 500,000 lbs U3O8) before final shutdown in 1971 (Figure 2).

Mineralization in the Kermac/Day Mine Area follows a similar configuration and was investigated by RME as a site for potential shallow uranium mineralization in the late 1970's. Previous production was from Tertiary bentonitic clay sediments overlying the basement granite.

A qualified person (as defined under NI 43-101) has not done sufficient work to classify the historical target estimates reported in this news release as current mineral resources or mineral reserves, and Myriad is not treating the historical target estimates as current mineral resources or mineral reserves. In particular, the Company considers that insufficient work has been done to estimate a resource at the Bonanza-Kermac property and the potential cannot be relied upon until further work is done.

Qualified Person

The scientific or technical information in this news release respecting the Company's Copper Mountain Project has been approved by George van der Walt, MSc., Pr.Sci.Nat., MGSSA, a Qualified Person as defined in National Instrument 43-101 – Standards of Disclosure for Mineral Projects. It is based on the Qualified Person's initial review of historical reports which were recently obtained by the Company. The Qualified Person considers the information to be relevant based on the amount and quality of work undertaken and reported historically. However, the information did not include original data such as drilling records, sampling, analytical or test data underlying the information or opinions contained in the written documents. Therefore, the Qualified Person has not reviewed or otherwise verified the information and has not done sufficient work to classify the historical estimates as current mineral resources or mineral reserves. A more thorough review of any available original data will be undertaken and reported on in more detail in future releases.

About Myriad Uranium Corp.

Myriad Uranium Corp. is a uranium exploration company with an earnable 75% interest in the Copper Mountain Uranium Project in Wyoming, USA. Copper Mountain hosts several known uranium deposits and historic uranium mines, including the Arrowhead Mine which produced 500,000 lbs of eU3O8. Copper Mountain saw extensive drilling and development by Union Pacific, which developed a mine plan and built a leach pad for one of the deposits at Copper Mountain. Operations ceased in 1980 before mining could commence due to falling uranium prices. Approximately 2,000 boreholes have been drilled at Copper Mountain and the project area has significant exploration upside. Union Pacific is estimated to have spent C$117 million (2023 dollars) exploring and developing Copper Mountain, generating significant historical resource estimates which are detailed here.

Myriad also holds 80% ownership of over 1,800 km2 of uranium exploration licenses in the Tim Mersoï Basin, Niger, with the option to earn up to 100%. These licenses are surrounded by many of the most significant uranium deposits in Africa, including Orano's 384 Mlbs eU3O8 Imouraren, Global Atomic's 236 Mlbs Dasa, and Goviex's 100 Mlbs Madaouela, and on the same fault structures. Myriad also has a 50% interest in the Millen Mountain Property in Nova Scotia, Canada, with the other 50% held by Probe Metals Inc.
