South Atlantic appoints Rees as technical adviser

Executive Summary

• South Atlantic Gold acquired an additional 4,200 ha of UAV magnetic survey data, bringing total UAV coverage at the Pedra Branca project to 6,800 ha.
• The company has begun re‑processing the full dataset with low‑latitude algorithms and integrating results into its Leapfrog 3‑D geological model to refine drill targeting.
• Matt Rees, P.Geo., former Iamgold chief geologist, was appointed technical adviser to the board to guide the ongoing exploration program.

Key Details

• Data Acquisition: Extra 4,200 ha of UAV magnetic survey data added; cumulative UAV coverage now 6,800 ha across the Pedra Branca project (total land package >48,000 ha).
• Re‑processing Work: Geophysics team applying low‑latitude algorithms to improve structural interpretation and highlight cross‑cutting anomalies.
• 3‑D Modelling Integration: Re‑processed magnetic data being incorporated into Leapfrog 3‑D model for enhanced target definition and depth continuity assessment.
• Technical Committee Role: Identified priority zones where magnetic anomalies coincide with geochemical trends and structural corridors; these areas slated for follow‑up mapping, sampling, and potential drilling.
• Oxide Starter Concept Review: Historical metallurgical data under review to evaluate feasibility of a near‑surface oxide starter operation alongside deeper orogenic gold targets.
• Appointment: Matt Rees, P.Geo., appointed technical adviser to the board; brings >40 years of international exploration experience, former Iamgold chief geologist (2018‑2025).
• Next Steps:
• Complete magnetic data re‑processing and QA/QC.
• Integrate results into Leapfrog for updated targeting.
• Conduct field validation (mapping, soil & stream‑sediment sampling).
• Review historic drill core for additional sampling opportunities.
• Define priority drill targets for the next exploration program at Pedra Branca.
