G2 Goldfields Receives Notice of Grant of Large Scale Prospecting Licenses of the Oko Gold Project

• Updated Mineral Resource Estimate (MRE) and Preliminary Economic Assessment (PEA) anticipated in Q4 2025
• G2 moves to rapidly advance multi-million ounce Oko Gold Project to production

G2 Goldfields Inc. (" G2 " or the " Company ") (TSX: GTWO; OTCQX: GUYGF) is pleased to announce that the Ministry of Natural Resources and Guyana Geology and Mines Commission have approved the issuance of two Large Scale Prospecting Licenses ("PL's") which encompass the Company's high-grade Oko-Ghanie Gold Deposit ("Oko" or the "Project") in Guyana.

Dan Noone, CEO, commented: "Securing the Prospecting Licenses for our flagship Oko-Ghanie Deposit is a significant milestone in the advancement of the Project and underscores our strong working relationship with the Government of Guyana. This approval provides a clear pathway to advance exploration and development of this world-class gold system. With this license in hand, we are well positioned to unlock the full potential of this highly prospective gold district and rapidly drive the advancement of this Project."

Patrick Sheridan, Executive Chairman, stated: "Guyana was recently recognized as a top ten jurisdiction globally for mining investment¹. This milestone is a testament to both the prolific prospectivity of the Guiana Shield and the Government of Guyana's strong support for the rapidly advancing gold mining industry, and foreign investment development in general. The Oko Gold Project is the second multi-million ounce gold mine that our group has discovered and developed in Guyana in the last twenty years, and we remain excited to continue to be a supportive partner in the development of the industry."

The Large Scale PL's encompass the Oko and Ghanie Deposits (1.5 million ounces indicated at 3.40 g/t Au and 1.6 million ounces inferred at 2.48 g/t Au) with a combined area of approximately 17,451 acres and replace 11 separate medium-scale mining permits previously held in the name of Guyanese entrepreneurs through option agreements. The PL's have a three-year term with two renewal rights for one year each and provides for the right of occupation and exclusive right to explore for gold and precious minerals.

Over the last two years, comprehensive environmental baseline studies have been conducted by G2 via third party consultants. These studies were designed to recommend actions for effective Project design, regulatory compliance and to support the preparation of an Environmental Social Impact Assessment ("ESIA"). Importantly, the Project area is not designated as a priority conservation site and does not overlap with any protected or Indigenous lands.
