Latin Metals Provides Update on

Esperanza Project, San Juan, Argentina

NR25-15 September 17, 2025

Vancouver, B.C. – Latin Metals Inc. ("Latin Metals " or the "Company") - (TSXV: LMS)

(OTCQB: LMSQF) is pleased to provide an update on the Esperanza ( "Esperanza") and Huachi

("Huachi") (together the "Projects") copper-gold projects in San Juan province, Argentina. Latin

Metals previously signed an option agreement (the “ Moxico Option ”) with Atlantic Metals

Limited, a wholly owned subsidiary of Moxico Resources plc (together with Atlantic Metals,

“Moxico”) (previous news release dated October 8, 2024).

Project Update

Moxico has made substantial progress at the Esperanza project to date. Geological work has

expanded the known footprint of mineralization and set the stage for future drill testing.

Geological and alteration mapping, systematic rock sampling, and the re-logging of historic drill

core have already identified new copper mineralization north and west of previously drilled

areas. International porphyry expert Dr. Richard Sillitoe has also completed a review of project

data, confirmed the presence of multi-phase mineralized intrusions and highlighted the potential

for extensions of mineralization beyond the zones defined to date.

In parallel, Moxico is advancing with programmed environmental and social works. Hydrological

and hydrogeological studies are underway in partnership with leading Argentine research

institutes, supported by newly installed weather stations across the Huerta de Huachi River basin.

On the social side, Moxico has retained San Juan–based ERS Consultora to complete a social

baseline study in the Department of Jáchal and has hired local staff to assist with logistics and

environmental monitoring.

This combination of technical, environmental, and social initiatives provides a strong foundation

for future drilling and positions Esperanza as a high-quality copper-gold project with district-scale

potential.

Esperanza Underlying Option

Latin Metals has amended the underlying option agreement ( "Amended Underlying Option ")

with the underlying vendor ("Vendor"). Under the terms of the amendment, the Vendor’s right

to terminate the option due to certain project delays has been removed. In consideration of this

concession, the payment schedule to acquire a 100% interest in the Esperanza property has been

amended (Table1) as follows:

beginning July 21, 2025.

Amended Moxico Option

Moxico has agreed to align its earn-in obligations with the revised terms of the amended

Underlying Option. Moxico has reimbursed Latin Metals for the US$250,000 milestone payment
