South Atlantic Gold Acquires Additional 4.2k hectares of UAV Magnetic Survey Data and Appoints Mr. Matt Rees, P.Geo., as Technical Advisor to the Board
(TheNewswire)
Vancouver, BC – October 9, 2025 – TheNewswire -South Atlantic Gold Inc. (TSX-V: SAO) (“SouthAtlantic” or the “Company”) is pleased to announce two importantdevelopments: the acquisition of an extra 4.2k ha (“hectares”)of UAV magnetic survey data followed by a comprehensive review of thecumulative total of all UAV data acquired to date (totaling 6.8k ha)at its Pedra Branca Project in Ceará State, Brazil, and theappointment of Mr. Matt Rees, P.Geo. as Technical Advisor to theBoard.
Douglas Meirelles, President and CEO of South Atlantic Gold, commented:
“We are excited to welcome Matt toour team. His 13 years of leadership at IAMGOLD, combined with hisglobal exploration expertise will be invaluable as we advance PedraBranca. At the same time, the recently acquired additional UAVmagnetic survey data provides us with a powerful new dataset that,under the guidance of our Technical Committee, will sharpen ourtarget definition and accelerate our path toward discoveryand development.”
UAV Magnetic Survey ReviewUnderway
As part of its strategy to delineate priority drilltargets and design the next exploration program at Pedra Branca, theCompany has commenced a detailed review of the UAV magnetic surveydata:
Magnetic DataReprocessing: The geophysics team has begunreprocessing the entire 6,800 hectares of UAV magnetic survey data(see Figure 1 map) using lowlatitude algorithmstailored to the region. This work is enhancing structuralinterpretation and highlighting crosscuttingfeatures of interest, and represents a small fraction survey area,across the Company’s districtscale PedraBranca land package of more than 48,000 hectares
Integration with 3D Modeling:The reprocessed data is being incorporated intothe Leapfrog™ 3D geological model, enabling refined drill targetingand evaluation of mineralized continuity at depth.
Technical CommitteeOversight: South Atlantic’s TechnicalCommittee has identified priority areas where magnetic anomalies alignwith geochemical trends and structural corridors, warranting follow-upmapping, sampling, and potential drill testing.
Advancing the Oxide StarterConcept: In parallel, the Company is reviewinghistorical metallurgical data to assess the potential for anear-surface oxide starter operation, while continuing to evaluatedeeper, high-grade orogenic gold targets.
Appointment of Matt Rees, P.Geo., asTechnical Advisor
Mr. Rees brings over four decades of internationalexploration and operational experience. He holds a M.Sc. in Geology fromthe University of Saskatchewan (1992) and is a registered ProfessionalGeoscientist (P.Geo.).

His career alsoincludes senior technical roles and advisory positions with severalcompanies since 1989. Mr. Rees is also an active member of theSociety of Economic Geologists (SEG). In 2023 he also assumed the Chair of the IndustryAdvisory Board to the MineralExploration Research Centre (MERC) under theMetal Earth (ME) project, part of the Harquail School of EarthSciences at Laurentian University.
Next Steps
- Completion of magnetic reprocessing and QA/QC.
- Integration of results into Leapfrog™ for updated3D targeting.
- Field validation through mapping, soil andstream-sediment sampling.
- Review of historical drill core for additionalsampling opportunities.
- Definition of priority drill targets for the nextexploration program at Pedra Branca.
