Omega Pacific Completes Exploratory Data Analysis at the GIC Prospect

Vancouver, British Columbia — March 4th, 2026 — CopAur Minerals Inc. (the “Company”) (CPAU:TSXV)

notes that Omega Pacific Resources Ltd. (“Omega”) has reported encouraging results from a

comprehensive Exploratory Data Analysis (EDA) at the GIC Prospect on Omega’s wholly owned Williams

Property in British Columbia’s Toodoggone District. CopAur currently holds 6.3 million shares of Omega

Pacific, representing approximately 15% of Omega’s issued and outstanding shares.

The study, as reported by Omega, integrates historical drilling, multi-element geochemistry, structural

data, soils geochemistry and geophysics into a preliminary 3D geological model, confirming a coherent,

structurally controlled gold system hosted within a mafic volcanic stratigraphic horizon traced over a

strike length exceeding 750 metres. Gold mineralization remains open along strike and at depth, with a

strong correlation identified between hydrothermal pyrite development and gold grades, providing clear

vectors to guide follow-up drilling.

As reported by Jason Leikam, the CEO of Omega, the EDA has materially reduced geological risk and

defined high-confidence targets for exploration drilling in 2026, while also highlighting a second target

area at the ROI Prospect, approximately 2 kilometres east of GIC, where soil anomalies indicate

potential porphyry-style copper-gold mineralization. Omega Pacific plans to advance the project

through targeted drilling to test extensions of known mineralization, expanded geochemical surveys and

continued refinement of its 3D geological model.

“We continue to believe in the potential of the Williams Property, and are very comfortable that Omega,

under Jason Leikam’s direction, has the requisite exploration management skills necessary to rapidly

move the project forward. The results of the EDA lay the foundation for a well-defined 2026 exploration

season. Omega’s assumption of 100% ownership of the Williams Property, as announced by CopAur in

November of last year, allows CopAur to maintain meaningful exposure to the exploration upside at

Williams through its equity position, while focusing the Company’s resources on developing the Kinsley

Mountain project.”, commented Andrew Neale.
