Western Metallica Resources Corp. reported on updates from the Company's mineral projects in Spain, specifically the launch of the Sierra Alta Project exploration program, with ten intended drill holes planned at a total depth of 200 metres, and across three main structural targets, refer to Table 1. The Sierra Alta Project is in the same prolific region as Penedela, located on the Southern edge of the strongly mineralised “Navelgas Gold Belt” which forms the central belt in Asturias, Spain, and consists of structurally controlled Palaeozoic clastic sediments and carbonates intruded by felsic intrusive rocks. The Sierra Alta Project is currently undergoing preliminary mapping, drill scouting, and a targeting program, conducted in parallel to the ongoing drill program at Penedela, see release dated September 28, 2022.

The Sierra Alta Project is a regionally encouraging project due to the compelling historical mining activity and the exploration data produced by Rio Narcea Gold Mines Ltd. in the 1990's and Emerita Resources Corp. in 2016, which presented high-grade gold in rock from NS striking jasperoidal breccias. An outstanding feature of the Sierra Alta Project is the vast alignment of several ancient Roman workings along a 10-kilometre trending corridor, direction NE-SW, combined with the presence of alluvial gold, an extensive project with 90 claims and a considerable amount of historical data to build upon.

The primary objective of the Sierra Alta Project includes drilling from the already approved sites at Montefurado and Puerto del Palo and pre-drilling activities such as a detailed and highly-representative diamond saw rock sampling program across the structures at Montefurado, Puerto Del Palo and La Marta prospects. The Sierra Alta Project holds over 4 kilometres of untested strike length remaining to be explored, as well as proven high-grade gold occurrences in the system, based on historical workings. A technical report prepared in accordance with NI 43-101 on the Sierra Alta Project, effective March 19, 2022.

Sample preparation and analyses are 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 and fine blanks, rejects and pulp duplicates.

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 ALS Loughrea, Galway, Ireland (ICP).
