Western Metallica Resources Corp. (TSX-V: WMS) is pleased to report that it has finalized a first phase drill program which included four drill holes for a cumulative ~1,500 metres of drilling completing half of the planned two-phase, ~3,000-metre drill program aimed at investigating the mineralization at depth below mine levels, as well as the northern and southern extensions (refer to press release dated May 11, 2023). Results of first phase of drilling include 7.40 metres at 0.6% Cu in NCDDH003, 1.65 metres at 1.7% Cu and 5.95 metres at 0.7% Cu in NCDDH004, among previously reported results from the first two holes, NCDD001 and NCDD002. Moreover, these results prove the on-strike continuity of the mineralization for ~300 metres, thus far, and intersected multiple intervals of significant copper mineralization in massive sulphides. Results of all four holes are meaningful as they equally indicate intersections of copper sulfide mineralization, over multiple intervals, predicting a broader high-grade copper mineralized trend and substantiating the vast historic data which positions Nueva Celti as a highly prolific copper project.
The results of the first phase confirmed the presence of the mineralized zones previously reported by the ‘Asturian de Zinc’, Glencore drilling program, and predict a high-grade copper mineralized trend. The mineralization is mainly represented by a “semi-massive”, >50% assemblage of pyrite, chalcopyrite and magnetite and ~2.3% disseminated ~chalcopyrite, defining strata bound-like bodies generally hosted by the mica-schists units. The control on the early-Cambrian mineralization is typical of the Cu-Zn-Pb occurrences on the Northern Central Belt (NCB) of the Ossa Morena geological province, with copper-sulfides mainly coinciding with layers of muscovite and biotite-schists, locally fragmental (meta-volcaniclastics) within an amphibolite unit (meta-volcanics).
There remains vast potential for further discovery as the first phase program only investigated the known mineralization ~100 metres below the deepest historical mine level and has also intercepted other mineralized zones closer to surface and at depth, not indicated by previous historic exploration/exploitation (refer to Figure 1).

Gregory Duras, CEO and Director of Western Metallica Resources commented, “Western Metallica’s exploration team are encouraged by the first phase drill program results that imply the continuity of the sulphide trend on strike and at depth and confirm the presence of higher-grade copper mineralized zones within the broader resource envelope, which furthermore includes credits of Zn, Pb, Au and Ag, as well as the potential northern extension delineated by NCDD003. Considering that this is only a modest 100 metres extension to the mine levels, the potential at depth remains unknown and highly prospective given the intervals historically reported, which were, to a certain extent, validated throughout Phase 1 of this drill program.”
Drill hole NCDD003, sited on the most northern section drilled to date (refer to both Figure 1 and Figure 2), proved that the historical mining ended in correspondence with the Peñaflor normal fault system that seems to have lowered a northern block for ~100 metres giving the potential for the mineralization to extend north below the Miocene marlstone and calcarenites.
Following this deduction, Western Metallica intends to execute a 30-kilometer ground mag, coupled with 300 gravimetric measurements, programs which are aimed at testing the possible continuity of the mineralization toward north and the possible repetition of the same mineralization style to the east.
In parallel to conducting a geophysics program at the Nueva Celti Copper Project, the Company is evaluating other prospective projects for acquisition in new jurisdictions, leveraging the Company’s strong cash position during an opportunistic period in the market, and delineating assets of interest that would further strengthen its portfolio of gold and polymetallic projects.

Quality Assurance and Quality Control
Sample preparation and analyses will be conducted according to standard industry procedures. Drill core samples are crushed, split and pulverized prior to analysis of Gold by fire assay and Atomic Absorption and multi-elements by ICP-AES after four acid digestion. Analytical performance is monitored by means of certified reference materials (CRMs), coarse blanks, coarse and pulp duplicate samples. Samples have been prepared in ALS Chemex preparation lab in Seville, Spain and analyses have been completed in ALS Rosia Montana, Alba, Romania (Fire Assays) and LAS Loughrea, Galway, Ireland (ICP).
