SOUTH ATLANTIC GOLD COMMENCES PHASE III MOBILIZATION
AT PEDRA BRANCA
Kelowna, British Columbia, [DATE], 2026 — SOUTH ATLANTIC GOLD INC. (TSX -V: SAO) (OTC Pink: JLRRF)
("South Atlantic" or the "Company") is pleased to provide an exploration update and announce the
commencement of mobilization for its fully funded Phase III diamond drill program at the Pedra Branca Gold
Project in Ceara State, Brazil (see Figure 1). The 5,000 -metre, approximately C$ 3.0 million program will
conduct diamond drilling across three targets.
Douglas Meirelles, President & CEO, stated: "During this initial phase of the current exploration program, we
will test whether Queimadas target potentially extends to the depths, and could be comparable to similar
documented hypozonal orogenic deposits, globally. As we advance this exploration program, and at the right
time we will also conduct additional drilling at Mirador and Igrejinha — our three resource targets in the
current NI 43 -101 Technical Report from 2021. The ongoing program will be guided by results not only from
these drilling programs, but all the additional geotechnical work and other support exploration activities
already underway. We look forward to providing shareholders with a steady flow of results beginning in Q2
2026."
Highlights
• Fully funded from C$4.2 million private placement closed March 2026; initiating IP geophysical survey .
mapping at depth, and drill potential extensions at Queimadas, Mirador and Igrejinha.
• Depth drilling at Queimadas — targeting depths significantly below the current RC drilling ore intercepts,
targeting at maximum of 200m to confirm the hypozonal orogenic gold system
• Multi-target diamond drilling program across three targets; field mobilization underway, drilling
expected late April 2026
Program Details
The Phase III program comprises approximately 5,000 metres of diamond drilling (HQ/NQ oriented core)
across three targets over approximately 8 months. Two drill rigs will be deployed, commencing at Queimadas
for deep testing and potential extensions before advancing to Mirador and Igrejinha.
Additional program elements include:
• IP geophysical survey: The Company's initial induced polarization survey will map the sulfide -bearing
zones at depth. The pyrrhotite -dominant sulfide assemblage at Pedra Branca is an ideal IP target.
Approximately 14 line-km of surveying at the Queimadas target extensions along the strike and dip with
a potential to extend to other targets.
• Core re-sampling: Additional historical diamond drill holes on those three targets to be re-sampled with
fire assay gold and ICP-MS 33-element geochemistry.

Queimadas — Depth Extension
Queimadas is the main host of the Pedra Branca NI 43 -101 Inferred Mineral Resource from 2021. Previous
diamond drilling at Queimadas returned gold mineralization that persists to the deepest levels tested:
• FCC002: 20.5m @ 4.69 g/t Au (grade x width = 96.1)
• FCC016: 1.0m @ 43.70 g/t Au at 90m downhole depth (isolated high-grade interval)
The deepest hole (FCC019, 201m) did not reach extent of the potential mineralized system.
Mirador — Southwest Expansion
Phase III will test the undrilled southwest extension at Mirador, following up on previous intercepts including:
• FMC008: 5.1m @ 9.35 g/t Au
Igrejinha — Discovery Target
Igrejinha has returned the strongest surface results in the Pedra Branca district but has never been tested by
diamond drilling. Previous work includes reverse circulation ("RC") drilling to a maximum depth of 52 metres
and extensive trenching, returning:
• TIG044: 6.4m @ 19.18 g/t Au (grade x width = 122.8)
All reported intervals are downhole lengths. True widths have not been determined.

Cautionary Note Regarding Mineral Resources
Inferred mineral resources are not mineral reserves and do not have demonstrated economic viability. There
is no certainty that any part of the mineral resources will be converted to mineral reserves. The mineral
resource estimate for the Pedra Branca Gold Project (4.0 Mt @ 1.38 g/t Au for 180,000 oz Au at a 0.40 g/t
cutoff) was prepared in accordance with NI 43-101 with an effective date of March 16, 2021, by Rodrigo
Mello, FAusIMM, of RBM Consultoria Mineral, and is filed on SEDAR+.
