Western Metallica Provides Update ON Planned Drilling Program at the Caña Brava Project

Exploration Programs

WESTERN METALLICA PROVIDES UPDATE ON PLANNED DRILLING

PROGRAM AT THE CAÑA BRAVA PROJECT

TORONTO, ONTARIO – March 25, 2024 – Western Metallica Resources Corp. (TSXV: WMS) (“Western

Metallica” or the “Company”) is pleased to provide an update on its current exploration activities aimed at

advancing the recently discovered Luz Maria and Caña Brava 1 prospects, two key copper-molybdenum

porphyry targets located within its 100% owned Caña Brava Project, and situated in the La Libertad

Department of Northern Peru.

Geophysical and field mapping crews are currently deployed at Luz Maria and Cana Brava 1, following up

on previous work conducted as it relates to strong magnetic anomalies coincident with large alteration

footprints, typical of Andean copper-molybdenum porphyry systems. The previous geophysical results and

field mapping confirmed the potential for a large porphyry Cu-Mo cluster under the sedimentary and colluvial

cover, providing valuable targets for further exploration, which the Company is now working to further

validate. Approximately 16-line kilometres of pole-dipole Induced Polarization (IP) geophysical surveys will

be completed near term, aimed at identifying sulphide rich mineralization and possible blind intrusions under

the strongly altered Cretaceous sedimentary rocks and under recent colluvium.

The acquisition of geophysical data is supported by an in -house geophysicist, with ample experience in

exploring for porphyry and intrusion-related systems in the Andes, responsible for the daily quality control

of the data, as well as for the processing and modeling. The Company is simultaneously acquiring

systematic portable-XRF soil data, aimed at vectorizing the Cu-Mo distribution at surface, as well as pole-

dipole IP geophysical data to identify sulphide -rich and/or resistivity anomalies , possibly indicating the

presence of mineralized bodies under the sedimentary and the recent colluvial covers.

The current field programs will allow the Company to extend mapping and sampling outside the main

creeks, where all outcrops of mineralized intrusive have been found to date, with the intent of confirming

the presence of significant and continuous Cu -Mo porphyry mineralization at a higher level of geological

confidence and across a more prominent alteration footprint. The Company believes that the integration of

this large dataset will provide a solid picture about the potential of both prospects, supporting the next phase

of scout drilling expected to commence by Q3-2024.

Previous work at the Luz Maria prospect successfully defined a 2.7-kilometre by 1.5-kilometre phyllic and

potassic alteration footprint, comparable in size to other major Peruvian porphyry deposits. A 46 diamond-

sawn channel sampling campaign displayed consistent anomalous grades up to 0.06% Cu and 0.03% Mo

from multi-phase intrusions, confirming at least three intrusion phases that host both Cu and Mo-sulphide

mineralization (refer to press release dated January 22, 2024).

Previous work at the Caña Brava 1 prospect confirmed at least a 1-kilometre by 1-kilometre sized porphyry

target characterized by a distinctive leached zone with goethite and hematite box works. A 17 diamond-

sawn channel sampling campaign had confirmed grades up to 0 .3% Cu and average 500 ppm Cu from

intrusive rocks.

Gregory Duras, Western Metallica’s CEO and Director, commented, “ We are systematically advancing

toward the definition of our drilling targets and moving efficiently through the permitting process, as we aim

to start our scout drilling program by Q3-2024. The highly-prospective porphyry targets which coincide with

Cu-Mo anomalies at both Luz Maria and Caña Brava 1 , defined across previous work and currently being

further validated and potentially extended, allows the Company to delineate key areas for the prospective

drill program. We are very excited with the evidence of these large, well -preserved porphyry systems

located in such a new, accessible, and socially favorable sector of La Libertad. It is unusual to find a virtually

unexplored exposed porphyry anywhere in the world, but particularly so in Peru, where some of the largest

porphyry discoveries of the past 50 years have been made. We look forward to updating the market on the

results of the first IP survey completed over the area, as well as the new sampling and mapping of this new

target located in one of the world’s premier porphyry belts.”

Background

Western Metallica holds the option to acquire 100% of the mineral claims, rights, and interests in two Cu-

Mo projects located in Northern Peru: Caña Brava and Turmalina (refer to press release dated August 10th,

2023). Both projects lie in a prolific Cu-Mo metallogenic belt, extending from Northern Peru into Ecuador,

which has seen notable exploration success and hosts world class discoveries and deposits such as La

Granja (First Quantum) , Cañariaco (Alta Copper), and Rio Blanco (Zijin Mining Group). The Company´s

projects are well located in proximity to industrial ports and major paved roads , and e ach project is

comprised of large mineral concessions conducive to future project scalability.

The Caña Brava Project is a highly prospective 5,700-hectare copper-molybdenum property located in the

La Libertad Department, only 35 kilometr es inland from the Peruvian coast and at an elevation of 1,500

metres in the western Cordillera of the Peruvian Andes. The Caña Brava Project is neighboring Hudbay’s

Llaguen Project which lies on the western margin of the Miocene epithermal -porphyry copper-gold belt of

Northern Peru, with the potential for Caña Brava to similarly host shallow high-grade mineralization across

a considerable alteration footprint.

Quality Assurance and Quality Control

Sample preparation and analyses will be conducted according to standard industry procedures. Rock

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 dupl icate samples. Samples are

prepared and analysed in SGS lab in Lima, Peru.
