Emerita Resources Announces Airborne Geophysical Survey Results and Mineral Resource Estimate Progress
TORONTO, April 07, 2026 – Emerita Resources Corp. (TSX-V: EMO; OTCQX: EMOTF; FSE: LLJA) has officially received and interpreted the results from its comprehensive helicopter time-domain electromagnetic and magnetic (HTEM) airborne geophysical survey. The survey, which was completed in December 2025, represents a significant advancement in the company's exploration efforts within the Iberian Belt West Project (IBW) area.
Extensive Survey Coverage and Geological Insights
The airborne HTEM survey encompassed an impressive 13,900 hectares over Emerita's mineral claims, including the IBW property and the adjacent San Antonio land package. This extensive coverage provides critical data for understanding the geological framework of the region. From a geological perspective, the survey area is characterized by two distinct domains that offer unique exploration opportunities.
The northern half of the area features what geologists refer to as the Blanket Rock Domain, where younger cover rocks create a thin layer estimated to be 0-200 meters thick. This domain presents particular challenges and opportunities for mineral exploration, as the cover rocks obscure the underlying formations that may contain valuable mineral deposits.
Host Rock Domain: Rich Historical Mining Area
In contrast, the southern half of the survey area comprises the Host Rock Domain, where volcano-sedimentary rocks serve as the primary host rocks for mineral deposits in this region. This domain includes numerous historic mines and prospects, with over 30 documented historical mining sites indicated by black symbols on geological maps.
The brightly colored volcano-sedimentary host rocks displayed on geological maps represent a significant exploration target area. Geophysical interpretation has successfully identified several promising targets within this domain, some of which coincide with known historical mineral deposits, including the La Romanera deposit.
Geophysical Targets and Exploration Strategy
The company's geophysical interpretation has revealed multiple targets that warrant further investigation. Emerita is currently conducting detailed mapping and structural interpretation of these identified geophysical targets to establish priorities for planned drilling programs. This systematic approach ensures that exploration resources are allocated to the most promising areas first.
In the Blanket Rock Domain, where younger sedimentary cover obscures the underlying Pyrite Belt formations, the company has identified windows where the prospective stratigraphy is exposed. These windows, where the cover is interpreted to be relatively thin (up to 200 meters thick), contain several known copper occurrences that suggest excellent prospectivity for mineral discovery.
Historical Context and Exploration Techniques
The use of deep-seeking geophysical investigation through younger cover rocks, particularly when coupled with gravity surveys, has proven to be a highly effective exploration technique in similar geological settings. This approach has led to many of the most significant mineral discoveries in the region over the past 50 years, including notable deposits such as Neves Corvo, Cobre Las Cruces, Masa Valverde, Magdelena, and Lagoa Salgada.
Emerita's survey also covered additional tenements under application by the company, including Tamujoso, Sampedro, Sonia, Secundino, and Rocio, which are currently awaiting final awarding by the mines department. This comprehensive approach ensures that the company has a complete understanding of the exploration potential across its entire landholding portfolio.
Mineral Resources Estimate Update
Alongside the airborne survey results, Emerita Resources has provided an update on its mineral resources estimate progress. The data collected from the HTEM survey will be integrated into the company's ongoing resource estimation work, potentially enhancing the understanding of mineralization patterns and distribution across the project area.
The combination of modern geophysical techniques with traditional geological mapping and historical mining data creates a powerful exploration toolkit that positions Emerita Resources for potential discovery success in the Iberian Belt West Project area.
