Corporate Updates

PALAMINA COMPLETES TRANSFER OF THE GABAN GOLD

AND ICA COPPER SILVER PROJECTS FROM WINSHEAR GOLD

FOR IMMEDIATE RELEASE

Toronto – June 5, 2025

Palamina Corp. (TSXV:PA, OTCQB:PLMNF): On April 11, 2025, Palamina received notice from

Winshear offering to return 100% ownership of the Gaban Gold and Ica Copper -Gold projects to

Palamina (see April 14, 2025 news release ). In accordance with the terms of the original purchase

and sale agreement, Palamina confirmed its intention to take back ownership, and the transfer process

is now complete.

Projects Overview

Gaban Gold Project: Located in the Puno Orogenic Gold Belt in southeastern Peru, the Gaban Gold

Project has been the subject of significant exploration including an airborne geophysical survey

completed in 2024 . Previous sampling campaigns had outlined a gold -bearing mineralized shear

zone extending over a 900m by 2,200m area. Surface samples collected in quartz-rich deformed

shear zones returned assays of up to 32 g/t gold. The fir st-ever 1,005 meter drill program was

completed in late 2024 and returned some notable intersections, including 4 meters of 5.04 g/t gold

and 21 meters of 1.29 g/t gold hosted in shales. These were from the two southernmost drill holes in

the Coritiri zone. The drill program was stopped earlier than anticipated due to the early onset of the

rainy season, which prevented drilling of some of the main targets to the southwest. The DIA

environmental permit with approved drill pads remains in place.

Ica Copper-Gold Project: Located 45 km southeast of the city of Ica at an elevation of 2,000 m and

300 km southeast of Lima along the Pan-American highway. The Ica iron oxide-copper-gold project

is an early -stage exploration target that covers an area of 2,933 hectares. I nitial reconnaissance

mapping and sampling programs have delineated several laterally continuous copper-gold veins and

magnetite rich replacement bodies hosted in a shallowly oxidized Jurassic aged volcanic sequence.

An airborne magnetic survey was completed in early 2024 to assess the possibility of a large

magnetite or sulfide rich mineralized body at depth.

Andrew Thomson, President of Palamina, commented: "We appreciate all the work and effort that

Winshear has undertaken in advancing these projects. Regaining ownership of the Gaban and Ica

projects, allows Palamina to strengthen its position as one of the most active junior exploration

companies in Peru, strengthening our portfolio o f precious and base metals projects in one of the

world´s premier exploration jurisdictions.”

The Company is conducting a comprehensive review of the claim blocks for both properties and may

choose to drop a portion of the claims that do not align with its exploration objectives. Mr. Thomson

has resigned from the board of Winshear Gold . Palamina no longer holds any equity nor has any

ongoing relationship with Winshear Gold.
