Exploration

Exploration at Pedra Branca spans multiple campaigns from 1980s discovery through to the current Phase III program. The consolidated database includes 903 data points (90 diamond drill holes, 163 RC holes, and 650 trenches) totaling 15,517m of drilling and 56,892m of trenching across 9 NI 43-101 targets (part of 13 identified anomalies).

The Maiden Inferred Resource of 180,000 oz Au (4.0 Mt @ 1.38 g/t, 0.40 g/t cut-off) was defined from only 3 of the 13 targets, drilled to an average depth of just 99m. Metallurgical testing confirms 92–98% gold recovery via conventional CIL processing, with 63.8% gravity-recoverable gold.

Phase III Exploration Program — Mobilization April 2026

On April 14, 2026, the Company announced commencement of mobilization for its fully funded Phase III diamond drill program at Pedra Branca. The 5,000-metre program will conduct diamond drilling across three priority targets over approximately 8 months, with two drill rigs deployed commencing late April 2026.

Program scope includes:

  • 5,000 metres of diamond drilling (HQ/NQ oriented core) targeting depth extensions and expansions at Queimadas, Mirador, and Igrejinha
  • Two simultaneous drill rigs: Queimadas (deep testing below current 201m maximum), Mirador and Igrejinha (depth extensions and southwest expansion)
  • Induced Polarization (IP) geophysical survey: Approximately 14 line-km at Queimadas, mapping sulfide-bearing zones at depth along strike and dip
  • Core re-sampling of historical diamond drill holes: Fire assay gold and 33-element ICP-MS geochemistry on three priority targets
  • First assay results expected in Q2 2026 with regular exploration updates throughout the program

Funding: The program is valued at approximately C$3.0 million and is fully funded from the C$4.2 million private placement closed March 13, 2026. A concurrent $500,000 debt settlement via 10 million shares at the placement price was also completed at close.

Queimadas is the main host of the 180,000 ounces gold Inferred Mineral Resource (NI 43-101, March 2021, 4.0 Mt @ 1.38 g/t Au, 0.40 g/t cutoff), with previous drilling returning persistent gold mineralization to 201m (FCC019). Mirador and Igrejinha, together holding resource material, have not yet been extensively tested at depth.

The Phase III exploration program is conducted under the supervision of Marcelo Antonio Batelochi, P.Geo., MAusIMM (CP), Senior VP Exploration, who is a Qualified Person as defined by NI 43-101-1F2. Matt Rees, P.Geo., a former senior geologist with IAMGOLD, serves as Technical Advisor to the project.

Drone Survey

The high resolution drone survey was successful in the identification of magnetic signatures that enable the geological team to locate areas of interest for future exploration.

Geology

Pedra Branca is classified as a hypozonal orogenic gold deposit hosted within the Troia Massif — Archaean crust reworked during the Brasiliano Orogeny (~600 Ma). Gold mineralization occurs in amphibolite-facies metamorphic rocks as shear-hosted and quartz-vein systems within amphibole schist, the signature host rock of hypozonal orogenic gold deposits worldwide.

The sulfide assemblage is pyrrhotite-dominant (po >> py > cpy), with gold associated with both disseminated sulfides (60–70% of intercepts) and high-grade quartz vein intercepts exceeding 90 g/t Au. Mineralization is controlled by NE-trending shear zones subsidiary to the regional Senador Pompeu Shear Zone, with second-order dilational jogs hosting the highest grades.

Depth potential: Hypozonal deposits globally extend 800–2,000m+ vertically (Hemlo: 21 Moz mined to 2,000m; Big Bell: 3.5 Moz to 1,200m; Challenger: 1.2 Moz to 1,000m). At Pedra Branca, the mean diamond drill depth is just 99m and the maximum is 201m — less than 10–20% of the expected vertical extent has been tested. Grade increases with depth at Queimadas (FCC016: 14.61 g/t at 91m), supporting the hypozonal model.

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, classified as Inferred) is not a mineral reserve and does not have demonstrated economic viability. Inferred resources cannot be used to estimate economic mineable reserves, and there is no certainty that any part of the resource will be converted to a mineral reserve. The resource estimate was prepared in accordance with National Instrument 43-101 with an effective date of March 16, 2021, by Rodrigo Mello, FAusIMM, of RBM Consultoria Mineral, and is filed on SEDAR+.
