Lara Exploration Announces Atlantica Results Confirm Potential 3km Strike Extension to Planalto Mineralization
Planalto Extension Potential Offsets Minsur Exit as Lara Eyes 3km Strike Growth
The most recent news release (January 19, 2026) provides an exploration update for the recently acquired Atlantica license, which is contiguous to the company’s flagship Planalto Copper-Gold Project in Brazil. Key highlights include: - Confirmation of a potential 3km strike extension to the Planalto mineralization. - Soil sampling identified three distinct anomalous copper zones. - Resampling of historic core at Atlantica yielded intercepts including 35.8 meters at 0.35% Cu (Oxide) and 4 meters at 0.64% Cu (Sulfide). - A drilling program of 2,000 meters is committed under the acquisition terms, with Lara planning to begin testing in late Q1 2026.
This news is materially positive as it provides a clear path to expanding the resource base for the Planalto Project, which recently (October 2025) received a positive Preliminary Economic Assessment (PEA). - Resource Growth: The 3km strike extension suggests that the current PEA pit (Silica Cap) could potentially be expanded or supplemented by satellite deposits, improving the project's scale. - Grade Considerations: While the extension is promising, the historical resampling grades (0.22% to 0.35% Cu) are generally lower than the Planalto PEA Indicated grade of 0.53% Cu. However, the presence of oxide mineralization (0.35% Cu over 35.8m) could offer lower-cost early processing options. - Counteracting Negatives: This exploration success helps mitigate the sentiment hit from November 2025, when Minsur S.A. terminated its option on the Lara Copper Project in Peru. The focus is now squarely on the Brazilian assets.
Lara Exploration is a project generator focused primarily on copper and gold in Brazil and Peru. - Flagship Project: Planalto Copper-Gold Project (Pará State, Brazil). - PEA Highlights: After-tax NPV (8%) of $378M USD, IRR of 21%, and a 18-year mine life. - Ownership: Lara moved to 100% ownership of Planalto, which is a significant pivot from its traditional project generator (minority interest) model.
