Western Metallica Reports Drill Program Results Including 26 Metres at 1.5% Copper From Its Nueva Celti Copper Project

TORONTO, May 11, 2023 - Western Metallica Resources Corp. (TSXV: WMS) ("Western Metallica" or the "Company") is pleased to report on the encouraging results of a second hole drilled at the Company's 100% owned Nueva Celti Copper Project, a past producing copper mine with significant exploration potential, located in the southernmost region of Spain.

The Company has completed three drill holes (results from NCDD003 are pending) for a total of ~1,150 metres of the planned two-phase, ~3,000-metre drill program aimed at investigating mineralized zones at depth below mine levels, as well as the northern and southern extensions (refer to Table 2 for drill hole details). Results of these drill holes are significant as they indicate that both the reported holes intersected copper sulfide mineralization, over multiple intervals, and as drilling continues, the Company anticipates new copper discoveries that will validate the vast historic data which positions Nueva Celti as a highly prolific copper project.

The results from the first two holes, NCDD001 and NCDD002, have confirmed the presence of the mineralized zones reported by the 'Asturian de Zinc', Glencore drilling program, and predict a high-grade copper mineralized trend. Per previously reported results from the Company's April 17^th press release, NCDD002 intercepted a wide, ~40-metre-thick zone of disseminated and semi-massive (>50%) assemblage of pyrite, chalcopyrite and magnetite. This highly prospective zone is hosted by the biotite-schists unit, ~100 metres below the deepest historical mine level, as well as confirming the presence of another ~8-metre-wide zone of disseminated and semi-massive sulfide, not indicated by previous historic exploitation.

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).

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).
