CHAKANA PROVIDES CORPORATE UPDATE & EXPLORATION PLAN FOR

LA JOYA PROJECT, PERU

Vancouver, B.C., June 2, 2025 – Chakana Copper Corp . (TSX-V: PERU; OTCQB: CHKKF; FRA:

1ZX) (the “ Company ” or “ Chakana ”), is pleased to provide this update and outline its exploration plan for

the La Joya project in Ancash, Peru. After eliminat ing all property payments and consolidating its sha re

structure, the Company is focusing its exploration efforts on three mineral rich target areas within the newly

defined La Joya project.

The La Joya project includes three principal target areas:

• the La Joya high-sulfidation epithermal (HSE) syste m, where minimal 2024 drilling confirmed

high-grade silver mineralization including 1,005.0 gpt silver and 0.45 gpt gold over 0.75m within

an alteration zone with 700 meters of strike length; and

• the Mega-Gold intrusive center, where 2024 scout dr illing confirmed a high-level porphyry

environment with two yet to be tested discrete porphyry targets; and

• the Compañero gold zone, where hydrothermal breccia is exposed at surface in several outcrops

over an area of 250 metres diameter with channel sample assays up to 14.4 gpt gold.

The La Joya project is located within an option agreement with Barrick Gold (NYSE:B; TSX:ABX)

(Figure 1) and has no property payments.

“The fully permitted drill targets at La Joya (HSE) and Mega-Gold are exciting discovery opportunities. We

have already encountered high grade silver mineralization in drilling at La Joya within the same stratigraphy

that hosts significant mineralization in the district. At Mega-Gold, our initial scout drilling, combined with

geophysics and geochemical zoning, provide strong v ectors defining two discrete porphyry targets” stat ed

President and CEO David Kelley.

2025 Exploration Plan

The La Joya (HSE) and Mega-Gold prospects are fully permitted for additional drilling. At La Joya (HSE),

detailed mapping and a detail ground geophysical survey will be completed prior to drilling. The target is a

stratigraphically hosted bulk tonnage precious meta ls deposit. Approximately 1,900m of drilling is

anticipated. At Mega-Gold, a definitive drill test of the PT-1 porphyry target is planned with an anticipated

depth of 400m. The final stage of permitting allowing drilling at the Compañero gold zone will be completed.

The environmental permit has been awarded with the initiation of activities remaining to be completed.

La Joya High-Sulfidation Epithermal Prospect

The La Joya (HSE) target area is associated with hi gh-sulfidation advanced argillic alteration consisting of

vuggy silica, alunite, dickite, zunyite, diaspore, and pyrophyllite. The zone of alteration extends 700 metres

- 2 -

in a north-south direction at an elevation of appro ximately 4,500 metres (Figures 1 and 2). Surface ro ck

samples collected from the alteration zone have sil ver and gold values up to 1,300 gpt and 0.36 gpt,

respectively.

Three shallow holes were completed at La Joya in 20 24 for a total of 465.5 m. The holes were planned t o

drill beneath strongly silicified volcanic rocks wh ere zones of vuggy silica alteration returned stron gly

anomalous values in silver and gold. The strongest mineralization was observed in hole LJDH24-002 with

323.6 gpt silver and 0.25 gpt gold over 4.5 m from 58.0 m depth. Within this interval vuggy silica is present

over a 0.75m interval with 1,005.0 gpt silver and 0 .45 gpt gold (see news release dated August 29, 202 4).

The mineralized interval is hosted within andesite tuff that shows evidence of advanced argillic alter ation.

Shallow drilling confirmed high-grade precious meta l mineralization hosted in prospective volcanic

stratigraphy and warrants additional drilling.

Mega-Gold Intrusive Center

The Mega-Gold intrusive center is a very large area occupying 2.5 km 2 with anomalous gold in soil overlying

pervasive tourmaline-quartz-white mica alteration, overprinted by localized advanced argillic alterati on

zones and tourmaline breccias. The target area is underlain by older andesitic tuff (Calipuy Formation) and

a pre-mineral granodiorite, thought to be the first pulse of intrusive activity in the Aija-Ticapampa district.

Within the gold anomaly is a distinct Offset (3D) induced polarization chargeability feature coincident with

the soil anomaly. Beneath the strong chargeability zones are discrete zones of conductivity, believed to

reflect mineralizing intrusions.

An initial “proof-of-concept” drilling program was completed in 2024 to test the idea that the Mega-Go ld

intrusive center is part of a mineralized porphyry system. A total of eight scout drill holes were com pleted

across a broad area totaling 2,425.20 m. These hole s display a variety of vein types (principally B an d D

veins); elevated gold, copper and molybdenum; and hydrothermal alteration zoning consistent with a high-

level porphyry environment (see news release dated August 29, 2024). All holes encountered pyrite-

chalcopyrite-molybdenite mineralization hosted in veins. Higher temperature alteration minerals suggesting

proximity to a porphyry are most strongly developed in the three eastern-most holes drilled in the Meg a-

Gold target area (see news release dated July 2, 20 24). These holes also exhibit narrow zones of stron g

mineralization in MGDH24-002 with 2.0 m of 1.8 gpt gold and 0.35% copper from 89.0 m depth, and 1.5 m

of 11.05 gpt gold from 127.5 m depth in MGDH24-003, confirming a mineralized fluid source at depth. The

strong IP chargeability zones are interpreted to be two separate pyrite shells related to underlying porphyry

intrusions. Strongly conductive rock beneath the pyrite shells are potential zones of porphyry mineralization

(PT-1, Figure 2 and 3) and warrant additional drilling.

Compañero Gold Prospect

The Compañero gold zone is located in the southwest part of the La Joya project adjacent to a pre-mine ral

intrusion. Mineralized hydrothermal breccias are ex posed at surface in several outcrops within an area of

approximately 250m in diameter. The breccias are strongly anomalous in gold with up to 14.4 gpt in channel

samples and secondary copper minerals are noted in several localities. Three heavy mineral concentrate

samples collected downstream and adjacent to the Co mpañero zone contain 19, 23, and 33 pristine gold

grains. There has been no drilling in the Compañero area.

1) precious metal mineralization at the La Joya hig h-sulfidation epithermal zone; 3) mineralization re lated

to the Mega-Gold intrusive center; and 3) the Compa ñero gold zone. In addition, Chakana owns a 1% net

smelter royalty over the Soledad property owned by Condor Resources in the active Aija-Ticapampa mining

district (see news release dated October 8, 2024). For more information on the La Joya project, please visit
