Lara Exploration Announces 14,000 Metre Validation Drilling Program Underway at the Planalto Project

About this update from Lara Exploration Ltd.

VANCOUVER, BC / ACCESS Newswire / June 29, 2026 / Lara Exploration Ltd. (TSXV:LRA)(OTC PINK:LRAXF), ("Lara" or the "Company") is pleased to report that seven diamond drill rigs are currently operating at the Planalto Project site, working on a 14,000 metre program designed to validate the geological-mineralization model presented previously in both the 2024 Lara Mineral Resource Estimation (MRE) and the 2025 Preliminary Evaluation Assessment (PEA) reports (see Note 1 below). Twenty-nine holes, for a total of 10,186 metres, have now been completed on the main Homestead-Cupuzeiro trend and a further 761 metres in four holes are now complete on the smaller satellite Silica Cap trend, located to the southeast of the main deposit. Additional infill diamond drilling, to bring the drill grid spacing to at least 100 metres by 100 metres, will be initiated once the geological-mineralization model validation is finalized. The intention is to bring most of the mineral resources within the previously defined PEA pit to the indicated or measured classification. Additional drilling will include some geotechnical study holes and some wider diameter holes for metallurgical testing. Homestead-Cupuzeiro Trend: Drilling on the main Homestead-Cupuzeiro trend has mainly concentrated on further defining the extent of the higher grade copper-gold zone (grades of 0.6 to 1.0 %Cu) in the central core zone of the Cupuzeiro sector, as well as, drilling along the eastern margin of this mineralized trend, which was less well constrained by the previous drilling, and where the geological modelling suggests potential for more relatively shallow near surface copper-gold mineralization. Geological logging of the recent drill cores indicates a wide zone (>100 metres) of near surface strong chalcopyrite mineralization in the core zone of the Cupuzeiro sector, which was not obvious in the previous drilling programs. The infill drilling program will focus on defining the extent of this higher grade (>1% Cu) copper zone. Analytical results for the samples from the completed holes are already starting to arrive from the laboratory and will be reviewed along with the QA-QC protocols for each drill hole. Silica Cap Trend: The recent drilling on this trend has been designed to increase the number of drill holes on each existing drill section (Drill cross-sections are available on the Lara we...
