TORONTO, March 20, 2023 (GLOBE NEWSWIRE) -- Emerita Resources Corp. (TSX – V: EMO; OTCQB: EMOTF; FSE: LLJA) (the “Company” or “Emerita”) is pleased to announce additional assay results from the ongoing 2022 - 2023 delineation drilling program at La Romanera Deposit, part of Emerita’s wholly owned Iberian Belt West project (“IBW” or the “Project”). Assays from an additional 14 drill holes have been received. IBW hosts three previously identified massive sulphide deposits: La Infanta, La Romanera and El Cura. All deposits are open for expansion along strike and at depth.
Assays are reported for the following 14 drill holes (LR022, LR027, LR031, LR036, LR039, LR048, LR055, LR063, LR068, LR070, LR072, LR099, LR110 and LR120) at La Romanera deposit (Figures 1, 2 and 3 and Table 1).
The 14 drill holes are broadly distributed, in the upper and central parts of the deposit, and on the edges of the known mineralization between +50 and -300 m elevation. The distribution of the drill holes has been designed to maintain a drilling spacing of approximately 50 x 50 m to support a high-quality mineral resource estimate. Work has begun on the initial National Instrument 43-101 (“NI 43-101”) mineral resource estimate (the “Resource Estimate”). The Qualified Person from Wardell Armstrong LLP has completed site visits and data has been transferred to complete the modeling required for the Resource Estimate
According to Ian Parkinson, EVP Corporate Development for Emerita, “Our team is excited to reach this milestone and start the process of putting together this interim mineral resource estimate. Drilling will continue to expand the resources, however we are confident that we have delineated sufficient mineralization with a tight enough drill spacing to support a robust and significant mineral resource estimate. Metallurgical sampling is expected to commence during the resource estimation phase.”
The Company recently surpassed 70,000 m of drilling on the IBW project, approximately 78% at La Romanera deposit and 22% at La Infanta deposit. Drilling continues with 15 rigs.

High grade polymetallic sulphide mineralization over considerable widths have been intersected in several of the deepest drillholes (below 500 meters) at La Romanera deposit (see news release dated March 2, 2023), and the deposit remains open at depth. To explore more effectively at depth, the Company has engaged the services of International Geophysical Technology (IGT), a specialized, independent geophysical contractor based in Madrid, Spain, which is carrying out a survey of the 4 deepest holes using Downhole TEM and Mise-à-la-Masse geophysical methods (Photo 1). This technology is designed to assist in targeting the deeper drilling to maximize the success of the program. It also has potential to identify additional sulphide lenses at depth that has been known to occur at other deposits in the Iberian Pyrite Belt which comprise several mineralized zones.

Quality Assurance/Quality Control
Drilling at La Romanera 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 Romanera and (8Km) from Infanta. 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 reassayed in such case. Once the data is approved by the QA/QC protocol assays are entered digitally directly into the database.
