Radius Signs Option to Acquire 100% of the Jonco Silver Project, Peru

(TheNewswire)

February 27, 2026 – TheNewswire - Vancouver, British Columbia – Radius Gold Inc. (TSXV: RDU)(“Radius” or the “Company”) is pleased to announce that it hasentered into an option agreement to acquire a 100% interest in theJonco Silver Project (the “Project”), a large-scale polymetallicsilver-gold-lead-zinc system located in central Peru.

The Jonco Silver Project hosts a bulk-tonnagedisseminated epithermal Ag-Au-Pb-Zn system associated with dacite flowdomes and diatreme breccias. Historical drilling has confirmedextensive mineralization from surface and defined potential for alarge-scale polymetallic system.

Project Highlights

• 3,830 hectares covering multiple drill and geophysicaltargets 

• 11 historic drill holes (3,195m) 

• Potential for a large polymetallic Ag-Au-Zn-Pbsystem 

• Disseminated open-pit style mineralization from surfaceto 250m depth 

• Mineralization hosted in dacitic flow domes anddiatreme breccias 

• Extensive geophysics includes over 30 line-km ofcombined ground magnetics and IP/Resistivity surveys 

Historical drilling highlightsinclude:

• Silver Zone: 

  • SAB-03: 254.5m @ 27.0 g/t Ag, 0.42% Pb, 0.71%Zn 

• Gold Zone:  

  • SAB-01: 85.5m @ 0.43 g/t Au, 14.1 g/t Ag, 0.56% Pb,1.26% Zn 

       AND 90.0m @ 0.32 g/t Au, 31.3 g/t Ag, 0.20%Pb, 0.56% Zn

Historical drill results are based on prior operator reporting andhave not been independently fully verified by Radius. See“Historical Drill Data and QA/QC” below. Reported intervals areinterpreted to approximate true widths; further works are required toconfirm this.

Note: The cross section integrates historicaldrilling with a Gross Metal Value (“GMV”) model used to outlinethe current interpreted extent and distribution of polymetallicmineralization. GMV values were calculated using assumed metal pricesof Au US$3,000/oz, Ag US$60/oz, Zn US$1.20/lb and PbUS$0.85/lb.

The GMV model is a geologicalvisualization tool only. It is not a mineral resource estimate, doesnot incorporate recoveries, mining or processing costs, and does notdetermine economic viability. Additional drilling and technicalstudies are required before any mineral resource can bedefined.

Geological Model and Upside

Mineralization at the Jonco Silver project isinterpreted as a large-scale polymetallic disseminated andreplacement-style Ag-Pb-Zn ±Au epithermal system hosted withindacitic flow domes and diatreme breccias. Mineralization is bothstrata-bound and structurally controlled.

The Company believes the system demonstratescharacteristics consistent with a large polymetallic bulk-tonnagedeposit. Geological modelling by the Radius Gold geological teamsuggests potential to initially define 50–100 million tonnes ofmineralized material through systematic drilling. Additional drillingand technical studies are required before any mineral resource can bedefined.

Comparable disseminated polymetallic Ag–Pb–Zn(±Au) systems include Iska Iska in Bolivia, Peñasquito in Mexico,Chinchillas in Argentina and Bowen's Silver deposit in Australia.These bulk-tonnage epithermal systems demonstrate that disseminatedsilver-rich polymetallic mineralization of similar grade tenor canachieve excellent economics where continuity andthickness are established.  The Jonco Silver property exhibitsgeological setting and grade characteristics consistent with thisstyle of epithermal mineralization; however, additional drilling willbe required to determine the extent and continuity ofmineralization.

At Jonco Silver, multiple untested targets have beendefined by property-wide magnetics and induced polarization surveysand geochemistry, with no significant exploration outside the centraldrilled zone that hosts these wide intercepts of polymetallic silverrich breccia and veins.

Infrastructure and Access

The Project is in a well-established mining region ofPeru with access via both coastal and highland routes from Lima.Proximity to major ports including Callao, Chancay and Pisco provideslong-term logistical advantages for future developmentscenarios.

Transaction Terms

Under a binding Letter of Intent, Radius may earn a100% interest in the Jonco Silver Project over five years throughstaged cash payments totalling US$4.15 million, US$7.0 million inexploration expenditures, and the issuance of 250,000 Radius commonshares.

Key terms include:

• On signing of the formal OptionAgreement (subject to TSXV approval):
  US$50,000 and 50,000 Radius shares 

• Upon grant of drill permits (FTA andInicio de Actividades):
  US$150,000 and 50,000 Radius shares 

• By the First Anniversary followingdrill permit grant:
  US$1.0 million exploration expenditures and 50,000 Radiusshares 

• By the SecondAnniversary:
  US$250,000; 50,000 Radius shares; and US$1.5 million explorationexpenditures 

• By the Third Anniversary:
  US$1.0 million; 100,000 Radius shares; and US$2.0 million explorationexpenditures 

• By the FourthAnniversary:
  US$1.2 million and US$2.5 million exploration expenditures 

• By the Fifth Anniversary:
  Final payment of US$1.5 million to earn 100% ownership 

Upon exercise of the Option and acquisition of a 100%interest in the Project, the vendor will retain a 2% Net SmelterReturn royalty. Radius may purchase up to 0.5% of the NSR for US$1.0million. Radius also holds an exclusive right to negotiate thepurchase of an existing 1.25% NSR royalty.

Community and Permitting

Previous drill permits associated with historicalexploration programs have expired. Prior to commencing new drilling,the Company will complete the standard permitting process applicableto regular mining concessions in Peru, including:

i. community authorization forsurface access,

ii. updated environmentalapproval through a Ficha Técnica Ambiental (FTA), and

iii. sectoral drill permits fromthe Ministry of Energy and Mines (MINEM).

The Company has initiated formal engagement with theComunidad Campesina de Cajamarquilla, which holds surface rights overportions of the project area. Meetings have been conducted withcommunity leadership and sector representatives to present theexploration program, address questions, and outline potentialcollaboration frameworks. Engagement to date has been constructive,and the Company is working through the community’s establishedinternal procedures to obtain the required authorization. In parallel,technical and environmental preparations are advancing in anticipationof drill permitting.

Next Steps

• Geological mapping and systematic surfacegeochemistry 

• Integration of historical drilling and geophysicaldata 

• Drill permit updates and preparation for initial drillprogram 

The Jonco Silver Project represents an advanced-stageAg-Au-Zn-Pb exploration opportunity with substantial scalepotential.

Historical Drill Data andQA/QC

Historical drilling comprises three diamond drill holescompleted in 1998 by Compañía de Minas Buenaventura and nine diamonddrill holes completed between 2004 and 2009 by Apex Silver Mines Ltd.,a Canadian-listed issuer at the time. The 1998 drilling predates theimplementation of NI 43-101, while the Apex drilling was completedfollowing its adoption. Reported results from both programs arebroadly consistent. Radius has reviewed available assay certificatesand drill logs, relogged selected core, and confirmed that assayvalues correspond with observed mineralization. Site visits includedverification of drill collar locations, review of mineralizedtrenches, and confirmation of extensive hydrothermal alteration. Whilethe historical data are considered relevant and reliable forexploration purposes, a Qualified Person has not independentlyverified all historical sampling and analytical procedures, andadditional work will be required to confirm the results.

Tierra Roja Copper Project Update

Radius continues to advance permitting for the TierraRoja copper project in southern Peru, where the Company is preparingfor its first drill program. Significant progress has been made towardsecuring the final authorization to commence drilling, although theadministrative process has taken longer than anticipated. Alltechnical preparations are complete, and the project is drillready.

Alejandro Ly, Vice President Exploration, commented:“Advancing the Tierra Rojadrill permit is a priority for Radius. Despite the bureaucraticprocess, we have made steady progress, and the technical team is fullyprepared. We look forward to commencing drilling as soon as the finalauthorization is received.”
