Western Metallica Resources Corp. Announces Update to Recently Launched Sierra ALTA Drill Program

WESTERN METALLICA RESOURCES CORP. ANNOUNCES UPDATE

TO RECENTLY LAUNCHED SIERRA ALTA DRILL PROGRAM

TORONTO, ONTARIO - December 6, 2022 – Western Metallica Resources Corp. (TSX.V: WMS)

(“Western Metallica” or the “ Company”) is pleased to report 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, refer to Figure 1.

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, a n extensive project with 90 claims and a

considerable amount of historical data to build upon.

Table 1: Sierra Alta Project Planned Drilling

The primary objective of the Sierra Alta Project includes drilling from the already approved sites

at Montefurado and Puerto del Palo, refer to Figure 2, 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, is available under

the Company’s SEDAR profile at www.sedar.com and accessible on the Western Metallica

website.

Gregory Duras, CEO and Director of Western Metallica Resources commented, “Western

Metallica intends to advance its exploration across various projects, in parallel, with a precise and

calculated exploration strategy to incrementally increase the potential of defining highly

mineralized zones and areas of future focus. The Sierra Alta Project is of exceptional importance

to the Company, notably due to it being surrounded by significant Roman historical workings, in

the robustly mineralised Navelgas Gold Belt, with notable high-grade gold occurrences within the

system which are validated by previous exploration activities. Unlike most exploration firms, we

are fortunate to operate in a structurally robust region, where three of our projects span over 8,500

hectares, much of which hosts historic workings and data.”

* Readers are cautioned that the Rio Narcea Gold Mines Ltd. and Emerita Resources Corp.

historical records have not been verified by a qualified person and should not be relied upon as

current. Additional work is required for the historical work to be verified and incorporated into a

current mineral resource estimate.

Quality Assurance and Quality Control

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).
