Gamma Resources Announces Archaeological Survey Program for Proposed

Mesa Arc Drilling Project in New Mexico

VANCOUVER, BRITISH COLUMBIA, March 1 6, 2026 Gamma Resources Ltd.

(TSXV:GAMA)(OTCQB:GAMXF)(FRA:MRDN) (“Gamma” or the “ Company”) is pleased that it

has engaged SWCA Environmental Consultants (“SWCA”) to conduct a Class III cultural resource

survey and archaeological investigation in support of the Company’s proposed drill program at its

Mesa Arc project in New Mexico.

The survey is a standard regulatory requirement prior to initiating exploration activities on U.S.

Forest Service lands and is intended to ensure compliance with federal cultural resource

protection regulations.

The work will support Gamma’s planned drill program designed to test mineralization through

drilling to depths of approximately 350 feet at four proposed drill locations, totaling approximately

10–12 exploration drill holes.

Gabriel Alonso-Mendoza, CEO and Director of Gamma, commented , “Advancing the Mesa Arc

project through the required baseline studies is an important step toward initiating our planned

drill program in New Mexico. Engaging a highly experienced firm such as SWCA helps ensure

that our exploration activities are conducted responsibly and in full compliance with federal land

management requirements. We look forward to completing this work and progressing toward drill

testing the mineral potential at Mesa Arc.”

About the Mesa Arc Project

The Mesa Arc Project comprises 41 lode mining claims in northern New Mexico, recently

expanded by 185 new federal claims to cover approximately 4,520 acres. The district hosts

documented uranium mineralization (McLemore & Chenoweth, 2017), with previous dr illing by

Magnum Uranium Corp. (2006).

The proposed drill program is designed to test priority targets within the Upper Rio Grande

watershed area of the Mesa Arc Project. The program will focus on validating historical data and

evaluating favourable stratigraphy and structural controls associated with uranium mineralization

in the region.

The Mesa Arc Project is located within a historically productive U.S. uranium belt. The planned

drilling is intended to confirm historical mineralization and support ongoing geological evaluation

of the project.

The archaeological survey will assess potential cultural resources within the proposed project

area and provide recommendations to the U.S. Forest Service regarding any mitigation measures

that may be required prior to exploration activities.

Upon completion of the field survey and submission of the final archaeological report to the U.S.

Forest Service, the Company expects to continue advancing permitting and planning activities

related to the Mesa Arc drilling program.
