Vancouver, British Columbia--(Newsfile Corp. - November 25, 2025) - CopAur Minerals Inc. (TSXV: CPAU) ("CopAur" or the "Company") announces that pursuant to the press release on November 24^th, 2025, by Omega Pacific Resources Ltd (CSE: OMGA) ("Omega"), that CopAur and Omega (the "Parties") have completed an amendment of the Williams Property (the "Property") Option/Joint Venture Agreement (the "Option Agreement") to accelerate Omega's acquisition of a 100% interest in the Property.

On February 29, 2024, the Parties entered into an Option Agreement (see CopAur's March 1^st, 2024, press release) whereby Omega could earn up to a 100% interest in the Williams Property. On April 24^th, 2024, CopAur announced the receipt of $1 million in cash and 3 million Omega shares from Omega, which along with agreed upon exploration expenditures and other considerations, allowed Omega to earn a 51% interest in the Williams property. On November 12^th, 2024, Omega exercised its option to acquire a 51% interest in the property.

On November 20^th, 2025, the Parties entered into a second amendment to the Option Agreement whereby Omega has the option to acquire the remaining 49% interest in the Williams Property from CopAur on or before December 4^th, 2025, by issuing to CopAur, 3.3 million common shares in the capital of Omega.

"CopAur is confident that the Williams Property, located in BC's re-emerging Toodoggone District and the Golden Horseshoe, which is widely regarded as a tier-one exploration region, holds tremendous, untapped mineral value as confirmed during Omega's 2024 drill program that returned values of 1.69 g/t Au over 104 metres and 2.16 g/t Au. over 96.9 metres. Omega has the requisite skill set to further develop this property, and this agreement allows CopAur to concentrate our efforts on our Nevada properties. We look forward to following developments at the Williams Property as a significant shareholder of Omega," commented Andrew Neale, CEO.
