(TheNewswire)

May 21,2025 – TheNewswire- V ancouver, British Columbia – Radius Gold Inc. ("Radius" or the “Company”)) announces that itswholly-owned subsidiary, Geometales del Norte – Geonorte S.A. deC.V., has signed a net smelter returns (NSR) royalty guaranteeagreement for the 12,462 ha Reducción Tlacolula 2  mineralconcession with JRC Ingenieria y Construcción SAC (“JRC”), aprivate Peruvian company which acquired the San José gold-silver minelocated in Oaxaca State, southern Mexico, from Fortuna Mining Corp. inApril 2025.

The Tlacolula property is located 25km east of the SanJose mining complex in Oaxaca, Mexico and hosts a high-gradeepithermal gold-silver mineralized system. The complex includes a3000t/day processing plant and underground epithermal gold-silver minewhich last reported by Fortuna Mining (March 2025) resources ofM&I 1.19MT @ 160 g/t Au and 1.15 g/t Au and Inferred 1.05MT @ 164g/t Ag and 1.23 g/t Au (note 1).

In addition to the Tlacolula NSR, Radius holds aportfolio of NSR and resource projects that have significant futureupside potential.

Highlights of the TlacolulaNSR:

• 2.0% NSR Royalty : Radius has a 2.0% NSR on future metal production from theTlacolula  property.

• Buydown Provision: The royalty may be reduced by up to 1.0% through cashpayments to Radius of US$1,500,000.

Historic exploration by Radius and Fortuna Miningidentified a large and low sulphidation epithermal vein system in theTlacolula concession. Highlights of the surface channel sample resultsinclude the following mineralized intervals:

•        6.30 metres averaging 19.34 grams pertonne gold and 986 g/t silver (open);

•        9.60 m averaging 0.13 g/t Au and 295 g/tAg (open);

•        3.30 m averaging 0.07 g/t Au and 234 g/tAg;

•        1.00 m averaging 4.28 g/t Au and 367 g/tAg;

•        1.50 m averaging 0.52 g/t Au and 561 g/tAg;

•        9.00 m averaging 0.22 g/t Au and 83 g/tAg (open).

The channel samples are generally oriented subperpendicular to the strike of the vein systems and are believed toapproximate true widths of the mineralized structures. Two main veinstotalling approximately 1,700 metres in strike length have beenidentified in the project area to date. These results demonstrate acompelling exploration target close to the San Jose miningcomplex.

Additional Radius NSR and ProjectHoldings:

• Option and exclusivity rights on the Tierra Roja copperproject area in southern Peru.

• 35% ownership of the Amalia project, Mexico in jointventure with Pan American Silver. Amalia has 23,058m of drillingcompleted in 67 drillholes, with significant resource potential.

• 40% ownership of the Holly project Guatemala, in jointventure with Volcanic Gold Mines. Holly project hosts and inferredmineral resource of 1.34MT @ 6.46 g/t Au and 256 g/t Ag for 272,110 ozgold and 10,913,360oz silver (note 2).

• Sliding scale royalty on the Tambor Gold Mine,Guatemala, owned by Kappes Cassiday and Associates. Tambor produced in2015 and 2016 and is currently on care and maintenance subject toarbitration with the Guatemalan government.  The agreement betweenRadius and KCA calls for Radius to be repaid from this royalty up to$10M, until the mine has produced 100,000 ounces of gold. After the$10 million has been paid, Radius will receive a minimum of $25 perounce of gold produced over and above the initial 100,000 oz.

Note2: Holly Mineral ResourceEstimate (see Radius press release June 9, 2022) is 1.3 Mt at 6.5 g/tfor 270,000 oz contained gold and 11 Moz at 260 g/t contained silver(effective date 7 June 2022). Resources estimated using a 3.0 g/t goldequivalent cut-off grade and a top cap grade of 100 g/t Gold and 2,000g/t Silver and presented on a 100%-basis. Gold Equivalent values arebased on Au$1800 and Ag$22 using the formula: Au g/t + (Agg/t*0.01222).

Mineral Resources are not MineralReserves and have not demonstrated economic viability. The estimate ofMineral Resources may be materially affected by environmental,permitting, legal, marketing, or other relevant issues. The mineralresources in this report were estimated using the Canadian Instituteof Mining, Metallurgy and Petroleum standards on mineral resources andreserves, definitions, and guidelines prepared by the CIM standingcommittee on reserve definitions and adopted by the CIM council.Notwithstanding, to meet the requirement that the reported MineralResources show “reasonable prospects for eventual economicextraction”.

The quantity and grade of reportedInferred resources in this estimation are uncertain in nature andthere has been insufficient exploration to define these InferredResources as an Indicated or Measured Mineral Resource. It isuncertain whether further exploration will result in an upgrade toIndicated or Measured Mineral Resource category.
