Gabo Mining Ltd. Announces Agreement to Acquire U.S. Uranium Projects and Proposed Name Change to Gamma Resources Ltd.

Vancouver, April 16, 2025 - GABO Mining Ltd. (TSXV: GAB | OTCQB: MLLOF | Frankfurt: MRDN) (the "Company" or "GABO") is pleased to announce that a wholly owned subsidiary of the Company (Medallion Research USA, Inc.), has entered into a lease agreement dated April 14, 2025 with C Bar B Properties Corporation (the "Vendor"), pursuant to which the Company has been granted a four year lease, with exclusive option to purchase, two advanced-stage uranium exploration projects located in Utah and New Mexico, United States (collectively, the "Projects"). In connection with the transaction and to reflect its sharpened focus on uranium exploration and development, the Company also announces its intention to rebrand as GAMMA Resources Ltd. The acquisition, the name change and the associated proposed new trading symbol "GARL" are all subject to approval by the TSX Venture Exchange.

"Rebranding to GAMMA Resources Ltd. reflects a deliberate and strategic realignment of our corporate identity with our mission to develop U.S.-based uranium resources that directly support the country's energy security and transition to a low-carbon future," said Gabriel Alonso-Mendoza, the Company's President and CEO. "Additionally, with our proprietary rare earth element (REE) extraction technology currently licensed to ACDC Metals Ltd (ASX: ADC) in Australia, we are expanding our role in supplying the critical raw materials essential to both national security and global clean energy objectives."

The two Projects subject to the lease agreement with the Vendor are described below. The Company's immediate focus will be on the Green River Project.

Green River Project - Utah

• Located in Emery County's San Rafael Mining District, the Green River Project comprises 41unpatentedlodeminingclaimstargetinguraniummineralizationinthe Salt Wash member of the Morrison Formation.

• TheprojectisadjacenttoWesternUraniumVanadium Corp'sSanRafaelProjectand lies just 11 km from the Maverick Minerals uranium/vanadium processing plant.

• Uranium deposits held by third parties near the Green River ProjectincludeDeepGold,DownYonder, 4484 Deposit, North Deposit, and Jackrabbit. Historicaldata for these nearby deposits north of the Green River Project described a combined total indicated resource of 3,404,593 lbs, and an inferred resource of 1,859,532 lbs?O? (see Gatten, O., 2014: NI 43-101 Technical Report On The San Rafael Uranium Project).

• Additionally, three nearby mines, the Snow, Lucky and Probe Mines, produced a total of approximately 1,000,000 lbs ?O? from the same formation between 1973 and 1982, (see Willbanks, L. 1982).

• The reader is cautioned that mineralization similar to that known from may adjacent project areas not be indicative of mineralization that may be discovered on the Green River Project.

Mesa Arc Project - New Mexico

• The Mesa Arc Project includes 41 lode mining claims in northern New Mexico. Historicaluraniumproductionandmineralization are well documented across the district (see McLemore V., and Chenoweth, W., 2017)

• Uranium mineralizedbodies have beenidentifiedinpriordrilling and were the subject of an internal resource estimate by Magnum Uranium Corp. in 2006

• PhaseexplorationplannedforQ2

*The historical mineral resource estimates quoted for the Mesa Arc Project are sourced from internal resource calculations performed by Magnum Uranium Corp. on 6/30/2006. Grade-thickness maps were published and a 'Thiessen Polygon Method' was used to calculate the resource estimates. There was no supporting technical report published with the resource calculation.

Data from summary logs of each drill hole giving the depth, thickness and grade of the intercept, was incorporated into a spreadsheet. All uranium grades were given in Ueq (equivalent uranium as determined by down-hole probe). A disequilibrium ratio of Ueq x 1.29 -0.001 was used to estimate the true grade. The true grade x thickness value was then assigned to each polygon.

These intercepts were added and a volume was calculated for each hole based on the area x thickness. A tonnage factor of 16 was used in the calculation based on the average density of sandstone. A tonnage was assigned to each polygon (cubic feet of a polygon/16 tons), then the pounds of U3O8 for each polygon was determined. Cut off grade in the calculations was .02 Ueq.

The historical mineral resource estimates for the nearby deposits held by third parties near the Green River Project use indicated and inferred mineral resource categories and are believed to have the same meaning per those resource categories set out in sections 1.2 and 1.3 of the NI 43-101 Standards of Disclosure for Mineral Projects.

Select historic drill holes shall be twinned to verify grade. Any historic holes remaining open could be probed to verify grade.

The above information was derived from historical information that has not been verified or confirmed by a Qualified Person (as defined below). Such information will be used to assist the Company in plans for ongoing work on the properties, but the reader is cautioned that results may not be repeated. No Qualified Person has done sufficient work to classify the historical estimates as current mineral resources or mineral reserves and the Company is not treating the historical estimates as current mineral resources or mineral reserves. Management cautions that past results on adjacent properties are not necessarily indicative of the results that may be achieved on the Projects being acquired.

"We are executing our strategy to build a U.S.-based portfolio of high-impact uranium assets with ISR potential," said Gabriel Alonso-Mendoza. "These projects offer scale, infrastructure advantages, and geological continuity with historically productive systems.

We look forward to initiating fieldwork in Q2 2025 as we advance toward our goal of delivering North American uranium supply."

The proposed acquisition is not a non-arm's length transaction and no finder's fees are payable.
