Big Gold Advances Martin Kenty Project on Cameron Deposit Trend; Plans 2026 Field Program

Toronto, Ontario--(Newsfile Corp. - May 27, 2026) - Big Gold Inc. (CSE: BG) (FSE: H7L) (the "Company" or "Big Gold") is pleased to announce the commencement of a comprehensive desktop review of its Martin Kenty Project in Ontario. The review, led by Morgan Verge P.Geo,. is a planning and target-generation exercise based on the body of historical exploration work conducted on the Martin Kenty Project and will aim to support a future drill program on the property. "Our desktop exercise is the disciplined first step ahead of a busy 2026 at Martin Kenty, which sits along trend from SEVA Mining's Cameron Deposit and within an increasingly active regional exploration corridor," said Scott Walters, CEO of Big Gold .

"Prior to future drilling, we will focus on a complete picture of what's already been done, with new technical eyes and favorable commodity prices. This will generate the right targets, prioritize the right ground, and make every field dollar count when we step into the spring/summer program." The Martin Kenty Project sits within a regional tenure footprint that includes SEVA Mining's Cameron Deposit, located along trend to the northeast of the Company's project area (Figure 1).

The first is the compilation of historical work: pulling together prior drilling logs, surface sampling data, mapping records, and any historical geophysical or geochemical datasets covering the Martin Kenty Project into a single integrated file server, complete with 2D and 3D databases.

The second is target generation for the 2026 field program: using the compiled dataset, together with the Company's current geological understanding of the property, to develop a ranked list of priority targets for follow-up field work. The output of the review is intended to inform the scope, prioritization, and budget of a planned spring/summer 2026 field program at Martin Kenty. Any subsequent field activity will be subject to financing, permitting, and exploration success and will be disclosed by separate news release in due course.

All technical information being reviewed is historical in nature, and while the Company and the Qualified Person consider the information to be generally correct and relevant to the project, it should not be relied upon. About the Martin Kenty Project The Martin Kenty Project is one of Big Gold's two flagship Ontario exploration properties, alongside the Tabor Project. The Project is at an early stage of exploration.

Historical exploration at the Martin Kenty Project has identified multiple occurrences of gold mineralization through surface sampling and prospecting programs completed by previous operators and the Company. During Big Gold's 2022 exploration program, grab samples returned values of up to 8.37 g/t Au and 8.04 g/t Au , helping define priority exploration areas associated with favorable intrusive and structural settings prospective for gold mineralization. 2 The Martin Kenty Project lies within the same regional tenure area as SEVA Mining Corp.'s Cameron Deposit, located along trend to the northeast of the Company's project area. SEVA has publicly reported a Mineral Resource Estimate at Cameron of 0.515 million ounces of gold Measured and Indicated at 2.44 g/t Au and 0.740 million ounces of gold Inferred at 2.18 g/t Au 1 .
