The 2026 program is an approximately 8-month exploration program targeting three priority zones at Pedra Branca:

• Drilling Program — 5,000 metres of diamond drilling (DDH) across Queimadas (depth extensions), Mirador (SW extension & stream sediment anomaly), and Igrejinha (high-grade veins)
• Soil Sampling — Regional and local geochemical programs to generate new targets across the 50 km prospective trend
• IP Geophysics — Short-term campaign to define structural controls and potential sulfide bodies

Very shallow. The average drill hole at Pedra Branca is only about 60 metres deep — essentially surface level for an orogenic gold system — and the deepest ever drilled reached just 201 metres. Phase III is now testing deeper: the June 30, 2026 program update reported gold mineralization intersected at 231 metres downhole, below all previous drilling.

For context, comparable orogenic gold deposits hosted in greenstone belts — such as those along Quebec’s Cadillac Fault Zone — are routinely mined at depths of 2–3 km. Magnetic data at Queimadas shows the mineralized structure plunging ~45° to the northwest, indicating significant untested depth potential.

Phase III drilling will specifically target depth extensions below current drilling limits at all three core targets.

South Atlantic holds a 100% interest in the Pedra Branca property, subject to underlying royalties to the original property vendors as follows:

• Base Metals: 1.0% royalty on gross revenues over any production
• Gold (M&I ≤ 200,000 oz): 0.5% royalty on gross revenues, plus a US$500,000 payment within 3 months of commercial production
• Gold (M&I > 200,000 oz): 1.0% royalty on gross revenues; 0.5% of this royalty may be purchased for US$750,000

Brazil’s mining sector is regulated by the Agência Nacional de Mineração (ANM), a federal agency directly linked to the Ministry of Mines and Energy.

The Company’s CEO, Douglas Meirelles, is Brazilian with over 20 years of experience operating in the country, and the on-site exploration team is locally hired as part of the Company’s commitment to responsible operations.

Infrastructure at Pedra Branca includes paved highway access (BR-020, approximately 280 km from Fortaleza), a nearby power line and local supply centres.

Per the January 2026 Corporate Presentation:

Phoenix Gold Fund Limited (BVI, managed by AIMS/Seraya Investment) holds approximately 11.0% based on its May 2025 early warning report filed on SEDAR+.
