Brasnova Energy expands Capela Gold Project sampling program

Vancouver, British Columbia--(Newsfile Corp. - August 13, 2026) - Brasnova Energy Materials Inc. (TSXV: BEM) ("BEM" or the "Company") is pleased to provide an update on the ongoing exploration program at the Capela Gold Project in Pintadas, Bahia, Brazil.

The current program builds on the encouraging rock chip results announced on July 14, 2026, including a peak assay of 4.13 g/t Au , and is focused on advancing the geological interpretation of the Capela Target, better defining the geometry and lateral extent of the mineralized system, and evaluating additional prospective occurrences identified beyond the original target area.

Detailed geological mapping, follow-up rock sampling, active stream sediment sampling and systematic soil sampling are being integrated to support the next stages of exploration. To date, five analytical batches totaling 110 samples have been submitted to SGS Geosol, comprising 52 rock samples , 14 active stream sediment samples and 44 soil samples , including quality assurance and quality control materials. An additional soil-sampling batch is in progress.

HIGHLIGHTS

Detailed geological mapping has continued within and beyond the original Capela Target.

Five analytical batches totaling 110 rock, active stream sediment and soil samples have been submitted to SGS Geosol, including QA/QC materials.

Follow-up rock sampling has targeted the interpreted extension of the known mineralized system and additional hydrothermally altered quartz-vein occurrences outside the original target area.

Systematic soil sampling is being conducted along lines spaced 100 metres apart, with sample stations at 25-metre intervals, to assist in defining the extent of the mineralized metagranodiorite body.

Mapping continues to document potassic alteration, silicification, stockwork quartz veinlets, sulphidation and gossan develo
