Western Metallica Resources Corp. Announces Update to Penedela Drill Program

Exploration Programs

WESTERN METALLICA RESOURCES CORP. ANNOUNCES

UPDATE TO PENEDELA DRILL PROGRAM

TORONTO, ONTARIO - September 28, 2022 – Western Metallica Resources Corp. (TSXV:

WMS) (“Western Metallica” or the “Company”) is pleased to report the re-start of the Penedela

Project drill program, following the announcement of the Vice President of Exploration

appointment, which led to the reprioritization of drill targets and advanced program planning. The

current phase of the 2,000-metre diamond drilling program, initially announced in May 2022, will

focus on significantly stepping out along trend from previous targets with the aim of testing

underexplored regions of the property. This phase of the Company’s drill program a t Penedela

intends to prove the property has the potential to host a million -ounce resource by prospectively

confirming higher grades and wider intercepts, and to fill-in data intervals within the current

structure.

The primary objective of the Company’s May-July 2022 drill program was to confirm the presence

of mineralization , prove its extension along strike and potential beyond previous exploration

programs. This phase had previously been paused to relog drill core produced from 2020 to 2022,

also involving the consolidation of a new coding system with detailed descriptions of the infill and

structures to reduce any risk of data loss throughout the logging process. The program planning

involved detailed mapping, rock sampling and a total of 640 metres drilled at a total depth of 291

metres achieved, refer to initial results in press release dated August 8 th, 2022. The program

successfully confirmed that the exploration potential remains open in both North and South

directions and at depth, with an indicated opportunity to intercept projected breccia veins, and

with five areas of specific interest moving forward (refer to Figure 1) . The diam ond drill holes

IB024, IB025 and IB026, although not indicators of high -grade results other than IB025 which

intercepted a low-angle core axis pyrite-arsenopyrite vein with 0.5 metre at 17.4 g/t Au, combined

with the reinterpretation of historical data, confirmed the below noted targets of significance.

Highlights of Drill Program Targets (refer to Figure 1):

1. Penedela Structure: the main breccia vein mineralization occurring at the sheared

contact between the Luarca shales and the Los Cabos quartzite was object of the previous

drilling and will not be object of the current drilling phase.

2. Saddle Reef and N-S Fault Target: Massive quartz veins traditionally coined ‘saddle reef

structures’ occur on the hinges of anticlines, this occurrence on the Penedela property

remains an untested region where recent field work indicated a folding style characterized

by a ‘short wave-length’ chevron structure, analogous to the regional San Martin anticline.

The chevron folding style combined with the presence of mineralization constrained by

lithological contact assumes the prospective presence of saddle reef mineralization, in

addition to recent 3D interpretation which infers the presence of a N10° fault as a possible

structure feeding the system. The initial planned drill hole F3IB -02 is intended to test this

hypothesis with a series of contingent holes, F3IB -05 and F3IB -006, to be drille d

southward on strike.

3. Cerro-East Target: Aimed to test the breccia contact in the western flank, a possible N-

S extension and evaluate at depth. Structural mapping, roman vestiges and geochemical

assay results support the untested target as a zone of potential interest which historically

returned 1 metre at 2 g/t Au (Drill Hole IB12 by Rio Narcea Gold Mines Ltd. , 1995). A

prominent >200ppb Au, N10°-striking soil anomaly, could be interpreted as a hidden N-S

fault to be targeted by the planned drill hole F3IB-01A, and drill hole F3IB-01B at depth.

4. E-W Structure Target: These N110 structures are observed to crosscut the chevron-style

fold hinges and may be related to a N -S extension. The related vein system will be the

object of selective channel sampling aimed to investigate its role within the gold

transportation and deposition, these veins could have been bypassed by previous drilling

that was oriented E-W. To evaluate the possible N-S extension of the E-W striking target,

saddle reef and N -S structures, a sector to the south across the Rio Linares defined as

the Zona Sur Del Rio target will be interested by holes F3IB-03 and F3IB-04, with the

secondary purpose to prove the occurrences of the N110° system observed in this region.

Indications of a gentle southern plunge of the fold axis confirmed from recent field observations

infer the Cerro -East, Saddle Reef, N -S Fault and E -W Structure targets may continue on a

southern trend. The drill program is anticipated to continue into November and will involve a step-

out aimed to evaluate previously identified but untested targets, with a strategy that involves

priority drill holes designed to test these targets and secondary holes contingent to the geological

evidence gathered from the prioritized target holes.

Management continues to view Penedela as a project of exceptional importance, notably due to

it being surrounded by significant Roman workings, in the robustly mineralised Navelgas Gold

Belt, and structurally comparable to other pro lific saddle reef and historical models. Gold

occurrences in the Asturias region are indicated across three belts, the Navelgas, Oscos and Rio

Narcea, and occurring in high -grade epithermal veins, skarns and as intrusive related gold

deposits. The Asturias region has been a significant producer of gold and hosts two of the largest

currently known deposits in the Iberian Peninsula, Salave and El Valle -Boinas Carles, both of

which are in close proximity to all three Western Metallica properties; Penedela, Val ledor and

Sierra Alta. Penedela remains a project of focus for the Company, being positioned in a prolific

region formed by multiple gold mineralizing events, with historical production estimated in excess

of 3 million ounces of gold.

As part of the reprioritization of the Company, Sierra Alta has been defined as a secondary focus

with preliminary mapping, drill scouting and targeting program planned in parallel to work

conducted at Penedela . The Company is fortunate to build off compelling historical work at the

Sierra Alta Project, where l imited exploration was conducted in the area by Rio Narcea Gold

Mines Ltd. circa 1990s, during 2005-2006 and 2014-2015, where geological mapping identified

numerous ancient Roman workings that align across a 10-kilometre NE-SW strike length and

historical pits such as the Freita pit from which 29 million tonnes of material is estimated to have

been mined. Rio Narcea Gold Mines Ltd. furthermore conducted soil sampling which identified a

series of gold anomalies over a n 8-kilometre strike length, the largest described as 3 kilometres

long and 300 metres wide located to the North and a second region of gold anomalies to the

South across an approximate 1.5 kilometres long and 200 metres wide area, as reported by

Emerita Resources Corp in 2016. Subsequent rock sampling conducted by Emerita Resources

Corp. in 2014 returned grades of up to 10.65 g/t Au, where decades prior, a 1 metre rock chip

sample reported by Rio Narcea Gold Mines Ltd. returned a striking grade of 338 g/t Au and results

of 48.96 g/t Au within an area of geochemical anomalies , proving that gold mineralization in the

Sierra Alta system has the potential for very high grades. There remains an untested strike length

of the Sierra Alta system which extends for more than 4 kilometres based on the distribution of

historical workings and soil anomalies . 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 digest ion. 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).
