Brasnova Energy Materials Inc. Reports Analytical Results from Rock Chip Sampling At Capela Gold Project

Brasnova Energy Materials Inc. announced analytical results from 23 rock chip samples collected from surface at the Capela Gold Project in Pintadas, Bahia, Brazil. The program follows the field activities announced on May 11, 2026, and was designed to verify historical gold occurrences and assess the continuity of mineralization within the Capela Target. Twenty-two of the 23 samples returned encouraging gold results with values ranging from 0.241 g/t Au to 4.13 g/t Au, confirming a mineralized north–south-trending corridor approximately 120 meters long and up to 25 meters wide. Additional results include 1.734 g/t Au, 1.435 g/t Au and 1.170 g/t Au. The mineralized trend defined by the current rock chip sampling remains open to the north and south along strike and laterally to the east and west, as the boundaries of the gold-bearing system have not yet been delineated. Gold is hosted by sheared and hydrothermally altered granitic to granodioritic rocks. Observed alteration includes potassic alteration, silicification and sulphidation, with disseminated pyrite and subordinate chalcopyrite and pyrrhotite. The Capela Project occurs within a structurally complex geological setting characterized by dextral and sinistral shear zones and regional fold structures. Geological mapping indicates that the target lies near the contact between granodioritic, granitic and metavolcanic–metasedimentary units, with mapped hydrothermal alteration developed within the broader intrusive and structural corridor. Rock chip samples were collected from granitic to granodioritic outcrops affected by intense ductile-brittle shearing and pervasive hydrothermal alteration. Sulphide mineralization is dominated by disseminated pyrite, visually estimated at approximately 1–3% by volume, with subordinate chalcopyrite and pyrrhotite. The sulphides are closely associated with the altered and structurally prepared zones. The analytical results indicate a hydrothermal system hosted within granitic rocks, characterized by potassic alteration, silicification and sulphidation, together with enrichment in gold (Au), copper (Cu), zinc (Zn), lead (Pb), silver (Ag), arsenic (As) and molybdenum (Mo). This geochemical association is consistent with the circulation of mineralizing hydrothermal fluids and the precipitation of polymetallic sulphides along structurally favorable zones. Samples were submitted to SGS laboratory in Vespasiano, Minas Gerais, Brazil, for preparation and geochemical analysis. Gold was analyzed by fire assay, while multi-element analysis was completed by ICP-OES/MS following multi-acid digestion. In addition to the laboratory’s internal quality assurance and quality control procedures, Brasnova implements an independent QA/QC program that includes certified reference materials and blank samples, with a minimum of one CRM and one blank inserted into every analytical batch. All results reported in this release passed the Company’s internal QA/QC verification prior to compilation and reporting. The Capela Gold Project is an early-stage gold exploration asset associated with a dome-shaped intrusive granodioritic system, structurally controlled by NW-SE and NE-SW corridors. Previous geological mapping identified hydrothermal alteration, sulphide-bearing outcrops, gossan zones and quartz-sulphide veinlets, features commonly associated with intrusion-related gold systems. The project is currently undergoing technical advancement under the NI 43-101 framework, with ongoing activities supervised as part of the Company’s exploration and validation strategy.
