Emerita Intersects 16.9 Meters Grading 1.4% Copper, 2.1% Zinc, 0.93 g/t Gold, 42.66 g/t Silver and 7.2 Meters Grading 1.0% Copper, 1.9% Zn, 1.31 g/t Gold, 60.10 g/t Silver at El Cura Deposit

TORONTO, Aug. 20, 2025 (GLOBE NEWSWIRE) -- Emerita Resources Corp. (TSX-V: EMO; OTCQB: EMOTF; FSE: LLJA) (the “Company” or “Emerita”) announces results from its ongoing resource expansion and in-fill drilling campaign at its El Cura deposit. El Cura is part of Emerita’s wholly owned Iberian Belt West project (“IBW” or the “Project”; Figure 1) which includes three Volcanogenic Massive Sulfide (VMS) deposits: La Romanera, El Cura and La Infanta.

El Cura deposit has potential to significantly increase IBW resource tonnes with additional high-grade gold and copper mineralization. The Company has approved an additional 10,000 meters of diamond drilling at El Cura due to the results of the program to date which demonstrate the deposit remains open for possible expansion at modest depth. This drilling will focus on converting the previously delineated Inferred Mineral Resource Estimate to an Indicated Mineral Resource Estimate in support of economic studies, as well as extending the lower and western regions of the known resource.

Recent results from the ongoing drilling campaign at El Cura include:

• Drill hole EC057: 3.1m grading 2.3% copper, 1.8% lead, 4.7% zinc, 2.21 g/t gold and 78.71 g/t silver, including a 1.9m interval grading 3.3% copper, 2.5% lead, 6.2% zinc, 3.13 g/t gold and 110.58 g/t silver.
• Drill hole EC062: 7.2m grading 1.0% copper, 1.4% lead, 1.9% zinc, 1.31 g/t gold and 60.10 g/t silver.
• Drill hole EC067: 16.9m grading 1.4% copper, 1.0% lead, 2.1% zinc, 0.93 g/t gold and 42.66 g/t silver, including a 3.1m interval grading 1.1% copper, 1.5% lead, 3.5% zinc, 1.46 g/t gold and 59.69 g/t silver.
• Drill hole EC068: 2.7m grading 1.3% copper, 1.0% lead, 3.2% zinc, 1.58 g/t gold and 46.59 g/t silver.

Discussion

Methodical definition drilling has shown a distinct westward plunge to the deposit and the Company continues to trace this trend with drilling. Additional drill holes are in-progress nearer to surface to rapidly and cost-effectively grow the resource up dip. The majority of the reported results are in the upper western, lower eastern and lower central portions of the deposit (Figure 3). To the east, holes EC049C, EC064 and EC066 tested the lower eastern portion of the deposit, and the heart of the eastern zone has returned the thickest intercept yet at El Cura, in hole EC067. The central portion of the deposit continues to return notable results, as indicated by holes EC063 and EC059B (Table 1). Hole EC068 returned the third highest interval gold and silver grades at El Cura (2.7m grading 1.58 g/t gold, 46.59 g/t silver), after holes EC034 (1.1m grading 3.47 g/t gold, 148.18 g/t silver) and EC029B (0.8m grading 3.93 g/t Au, 213.00 g/t silver). In accordance with the westward plunge of the mineralization, holes EC060 and EC061 limit the upper margin of the deposit to the west, passing above the plunge of the massive sulphide layer, 130m from surface. 

El Cura holds significant expansion potential at depth. With over 70 holes completed in the program, Emerita has demonstrated mineralization is more extensive than indicated by historical work in the 1970s and 1980s by previous operators. In the historical program, a single hole that tested 73m below surface was thought to close the deposit to the west but was too shallow to intercept the plunging mineralized zone. Emerita hole EC046 intercepted 8.9m grading 1.1% copper, 0.3% lead, 0.0% Zn, 1.21 g/t gold and 15.48 g/t silver 230m below the historic hole. Likewise, the deepest historical hole anywhere at El Cura intercepted the zone of interest 220m below surface, passing through a weakly mineralized zone of unsampled “low-grade”. On this same section however, Emerita has intercepted 1.7m grading 0.9% copper, 2.1% lead, 4.1% zinc, 2.12 g/t Au, and 69.82 g/t Ag in hole EC021, 270m below the historic blank hole and 413m below surface; as well as 3.0m grading 0.9% Cu, 1.3% Pb, 1.1% Zn, 1.33 g/t Au, and 53.46 g/t Ag in hole EC053, 214m below the historic blank hole and 357m below surface, among others. The Company will continue to delineate the El Cura resource which has not been fully outlined and potential exists well below the historic, superficial investigations.

“The ongoing success of the drill program at El Cura has led us to approve an additional 10,000 meters of drilling as the deposit remains open for expansion and continues to deliver intercepts of excellent thickness and grade. We are particularly interested in the improved understanding of the structural controls of the mineralization which suggest that previous investigators walked away without fully exploring the down plunge potential at El Cura,” states Joaquin Merino P.Geo., President of Emerita.

Quality Assurance/Quality Control

Drilling at El Cura is HQ size and core is placed into core trays at the drill site and transported directly from the site to Emerita’s coreshack (15Km) from El Cura. Once the cores are received at Emerita's coreshack they are photographed, and geotechnical logging is performed. Geological, mineralogical and structural logging follows and mineralized zones are identified. The samples are marked every 1m or less, and respecting lithological contacts, with most of the samples 1.0m long. The zone immediately above and below the mineralized zones are also sampled. Core samples are sawed in half and half of the core is returned to the core tray for future reference. Once the core samples are cut, bagged and tagged, they are shipped to the ALS laboratory in Seville by Emerita personnel where sample preparation is done. In Seville, ALS performs the mechanical preparation of the samples and then the pulps are sent to ALS Ireland (ICP) and ALS Romania (fire assay). The analysis at ALS Lab corresponds to the ME-ICPore (19 elements) package, together with the Au-AA23 fire assay (Gold).

10% of the analyzed samples correspond to control samples (fine blanks, coarse blanks, high, medium and low-grade standards). In addition, 10% of pulps are reanalyzed at a second independent certified laboratory (AGQ Lab Sevilla). When the analysis is completed, the certificates are received from the laboratory and the QA/QC protocol identifies any deviation or anomaly in the results and the entire batch is re-assayed in such case. Once the data is approved by the QA/QC protocol assays are entered digitally directly into the database.
