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.
The Pedra Branca project is a mesothermal gold deposit hosted in the Troia greenstone belt in the Brazilian Archean terrain. The exploration programs at Pedra Branca have been systematically using soil sampling, trenching, RC drilling and drone geophysical magnetics to determine the controls on mineralization and grade variability at the project.
The strike length of mineralization at Pedra Branca has been extended from 2 km to 14 km as a result of the exploration programs. The mineralization has only been tested to an approximate depth of 40 m.
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.
