The Pedra Branca Project is located in the state of Ceará in northeastern Brazil, across the municipalities of Pedra Branca, Tauá, Boa Viagem and Independência. The project is approximately 280 km southwest of the city of Fortaleza. Access from Fortaleza to the Pedra Branca Project is via paved highway BR-020.
The project consists of 24 Active Mineral Exploration licenses and three on Mining Concession stage.
- Initial 75% Earn-In with option with Jaguar Mining Inc. (TSX:JAG) as partner in future Joint-Venture. Provision to get 100% earn-in.
- 24 mineral exploration licenses covering 38,926 ha
- Excellent infrastructure in and around Project area including power, paved roads and mine facilities
- 9 km of drillingalready complete

Marcelo Antonio Batelochi (P.Geo.), MAUSIMM (CP), the Company’s Sr Exploration Manager is the Qualified Person as defined by National Instrument 43-101 who supervised the work program and preparation of the technical data on this webpage.
Pedra Branca Project is within in the Ceará Central Domain, which is located in the northern portion of the Borborema Province and comprises the Troia-Pedra Branca and Ceará Central Complex. The Troia-Pedra Branca Block, an important unit that is part of this domain, is represented by granite-greenstone and granite-gneissic terrains, classified in large part as Tonalite-Trondhjemite-Granodiorite (TTG) suites.

- Five lithotypes units based on previous Exploration data available. With the NNE-SSW axis, four of them (1 to 4) are stratiform, and unit 5 occurs to the north, truncating the others:
- Unit 1 – predominantly comprised of quartz-feldspar gneisses with biotite and muscovite; hornblende-gneisses and quartz-feldspathic gneisses;
- Unit 2 – composed of fine-grained gneisses interspersed with schists, fine amphibolite sometimes with garnet, hornblendite and tremolite;
- Unit 3 -mainly composed of schists characterized by intercalations of biotitic and quartz-feldspar shales, fine amphibolitic gneiss and fine amphibolites;
- Unit 4 – supports Serra da Pipoca and is dominated by feldspar and biotic quartz;
- Unit 5 – thick gneiss assemblage. The biotite-quartz-feldspar gneiss predominates with quartz-feldspathic intrusions.
- Gold mineralization is associated with the presence of sulfides and occurs at a level of amphibole shale with magnetite.
- Sulfide: pyrrhotite > pyrite >> chalcopyrite and arsenopyrite, thin, widespread, accompanies the foliation of the rock, concentrating on the foliation planes and locally on fractures.
Identified gold mineralization at the Pedra Branca Property is recognized by most of the geological community as mesothermal shear zone hosted gold deposit, associated to the Senador‐Pompeu shear zone. Mineralization generally occurs associated with quartz veinlets parallel to the foliation (Coelho and Queimadas targets) and sub‐metric to meter milky quartz veins at the Mirador and Igrejinha targets. Mineralization is often continuous to considerable depths in these systems.
Igrejinha is one of our main targets alongside Coelhos and Queimadas. The RC drilling at Igrejinha was designed to better understand the geology, structure and controls on the known mineralized zones and their extension along the trend zones in order to support further exploration programs, following the Orogenic Gold Mineralization Model that is often continuous in significant depths in these systems.
The gold mineralization at Igrejinha is characterized by subparallel intra-foliated millimetric/centimetric strings of sulfides in amphibolite shale with magnetite and fine quartz-feldspar rock, subordinately by hydrothermal silicification zones and pyrite >> pyrrhotite sulphides.
The Igrejinha target continues to be the main focus of the Phase 1 RC drilling program, with PB-RC-002 returning 1 m grading 5.9 g/t from 22 m depth, and PB-RC-003A intercepting 3 m at 1.13 g/t Au from 5m depth. Trenches at Igrejinha, PB-TR-009 and PB-TR-006 returned 6 m grading 7.19 g/t Au, and 29 m grading 0.73g/t Au (Including 3m at 3.22g/t Au), respectively.

Gold mineralization is Identified as mesothermal shear zone hosted gold deposit, associated to the Senador‐Pompeu shear zone. Mineralization generally occurs associated with quartz veinlets parallel to the foliation at the Coelho- Queimadas Target. Typical shear zone structural elements are not evident in the field and hydrothermal alteration occurs locally and in a few meters halo in the tremolite‐actinolite schists, chlorite schists and biotite‐gneiss that constitute the wall rocks. Strong silicification is present in all targets while eventual biotite, epidote, diopside and carbonate alteration occurs at the Coelho‐Queimadas targets
The gold mineralization at the Coelhos-Queimadas Project is characterized by the subparallel intra-foliated millimetric/centimetric strings of sulfides in amphibole shale with magnetite and fine quartz-feldspar rock, subordinately by hydrothermal silicification zones and pyrite >> pyrrhotite sulphides.
