Copper Giant Announces Updated Mocoa

Inferred Mineral Resource of 1.1 Billion Tonnes

at 0.51% CuEq* (0.31% Cu and 0.039% Mo)

Mocoa's High-Grade Core: Sensitivity table shows 190 million tonnes at 0.94% CuEq (0.53% Cu,

0.077% Mo) at a 0.70% CuEq cut-off.

Near-Surface Scale & Grade:

Resource is constrained within conservative 0.65 Revenue

Factor shell using

US$4.0

/lb copper,

US$20.0

/lb molybdenum at a cutoff of 0.25% CuEq* and

still surpasses one billion tonnes, placing Mocoa in a small peer group of large, high-grade and

near-surface copper deposits globally.

Major Resource Growth:

The updated resource at 1.12 billion tonnes at 0.51% CuEq* shows

a +76% increase in tonnage, +14% increase in CuEq* grade, and +101% increase in contained

CuEq* metal at the same 0.25% CuEq* cut-off as the 2022 MRE.

Efficient Drilling Impact:

9,525-metres drilled since the 2022 MRE added 671,000 pounds of

CuEq* per meter drilled.

Early Expansion:

All drilling was completed around the margins of the previous model. The

system remains open laterally and at depth, with multiple untested nearby porphyry targets.

Mocoa is still in early-stage growth.

One of World's Largest Undeveloped Molybdenum Resources:

Mocoa now hosts over one

billion pounds of molybdenum, placing it among the largest undeveloped molybdenum systems

globally. Molybdenum is designated a U.S. critical mineral for its role in high-strength steels,

energy infrastructure, and defense applications, with supply concentrated outside

the United

States

.

Unencumbered Resource:

The entire resource and constraining shell lie outside any forestry

reserve or any community.

Nov. 24, 2025

/CNW/ - Copper Giant Resources Corp. ("

Copper Giant

" or the

"

Company

") (TSXV: CGNT) (OTCQB: LBCMF) (FRA: 29H0) announces an updated Mineral

Resource Estimate ("

MRE

") for its 100%-owned Mocoa copper-molybdenum porphyry project in

southern

Colombia

. The updated estimate, prepared by APEX Geoscience Ltd. ("

APEX

"), in

accordance with National Instrument 43-101 –

Standards of Disclosure for Mineral Projects

("

NI 43-

101

"), incorporates 9,525-metres drilled since the 2022 MRE, enhanced geological interpretation,

updated metallurgical data, and revised long-term copper and molybdenum price assumptions. Two

drill rigs continue operating at full capacity as part of the ongoing 14,000-metre drill program at

Mocoa.

"Mocoa has now joined a very small group of near-surface copper systems worldwide that

exceed a billion tonnes — and we're still drilling at the edges. Add strong grades, clean

metallurgy, proximity to infrastructure, and a community that has been actively engaged since

day one, and you have a project being advanced exactly as a major, long-life asset should

be. This milestone comes at a time of structural copper deficits and accelerating global

demand. Mocoa is precisely the kind of asset the world needs. We've been drilling

continuously for twelve months, and we'll keep expanding the system while advancing toward

economic studies to build something with meaningful global and local impact" –

Ian Harris

,

President & CEO.

"Mocoa represents a rare, long-lived and multi-phase porphyry copper-molybdenum system,

with mineralizing activity spanning approximately ten million years. Drilling routinely delivers

several hundred to over a thousand metres of continuous mineralization, complemented by

robust high-grade intervals. In this update, we expanded the high-grade breccia and

delineated two additional high-grade porphyry phases. This combination of extensive

disseminated mineralization with concentrated high-grade zones is a hallmark of exemplary

porphyry systems.

The updated constrained resource model also highlights significant untapped potential: large

portions of the optimized shell remain completely undrilled and are currently classified as

waste, providing immediate, low-risk opportunities for ongoing drilling. The deposit remains

open laterally and at depth, and several nearby porphyry targets have yet to be tested.

We are still in the early stages of defining what geological evidence strongly suggests is a

broader Jurassic porphyry cluster at Mocoa." -

Edwin Naranjo Sierra

, Vice-President of

Exploration.

Notes

1.

The MRE was completed by Kevin Hon, B.Sc., P.Geo., Senior Resource Geologist, and Warren Black, M.Sc., P.Geo., Senior Consultant: Mineral Resources and Geostatistics,

both of APEX. Mr. Hon and Mr. Black are independent Qualified Persons, as defined by NI 43-101, and are responsible for the completion of the Mineral Resource Estimate, with

an effective date of November 18, 2025. Michael Dufresne, M.Sc., P.Geo., President & CEO of APEX, completed a peer review of the estimate.

2.

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

3.

The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

4.

The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral

Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could potentially be upgraded to an Indicated Mineral Resource with continued exploration.

5.

The Mineral Resources were estimated in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves,

Definitions (2014) and Best Practices Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.

6.

Economic assumptions used include US$4.00/lb Cu, US$20.00/lb Mo, process recoveries of 90% for Cu and 95% for Mo, a US$10/t processing cost, G&A costs of US$1.00/t,

and a 3% NSR royalty

7.

CuEq* values are calculated using a Cu-to-Mo value ratio of 1:5.278, incorporating both metal prices and metallurgical recoveries.

8.

The constraining pit optimization parameters include a US$2.5/t mining cost for both mineralized and waste material and 45° slopes. Pit-constrained Mineral Resources are

reported at a cutoff of 0.25% CuEq*.

Resource Estimation Methodology and Parameters

Mineral Resource modelling was conducted in UTM Coordinate system relative to the World

Geodetic System 1984 ensemble / UTM zone 18N (EPSG:32618). The MRE utilized a block model

with a size of 10 metres (X) by 10 metres (Y) by 10 metres (Z) to honour the mineralization

wireframes for estimation. Copper (Cu) and molybdenum (Mo) grades were estimated for each

block using Ordinary Kriging with locally varying anisotropy to ensure grade continuity in various

directions is reproduced in the block model. The reported open-pit resources utilize a cutoff of

0.25% CuEq*. The resource block model underwent several pit optimization scenarios using

Deswik's Pseudoflow pit optimization. The resulting conceptual 0.65 revenue factor pit shell is used

to constrain the reported open-pit resources. The MRE is reported as undiluted.

Quality Control and Quality Assurance

Copper Giant operates according to a rigorous Quality Assurance and Quality Control (QA/QC)

protocol consistent with industry best practices. Core diameter is a mix of HQ and NQ depending on

the depth of the drill hole. Diamond drill core boxes were photographed, sawed, sampled and

tagged in maximum 2-metre intervals, stopping in geological boundaries. Samples were bagged,

tagged and packaged for shipment by truck from Copper Giant's core logging facilities in Mocoa,

Colombia

to the ActLabs certified sample preparation facility in

Medellin, Colombia

. ActLabs is an

accredited laboratory independent of the Company. Samples are processed in the

Medellin

facilities

where they are analyzed for copper, gold, silver, molybdenum, zinc and lead by 4-Acid digest Atomic

Absorption (AA) analysis. The sample pulps are air freighted from

Medellin

to the ActLabs certified

laboratory in

Guadalajara, Mexico

, where they are analyzed for a suite of 57 elements using 4-Acid

digest and ICP-MS. In order to monitor the ongoing quality of assay data and the database, Copper

Giant has implemented QA/QC protocols which include standard sampling methodologies, the

insertion of certified copper and molybdenum standard materials, blanks, duplicates (field,

preparation and analysis) randomly inserted into the sampling sequence. QA/QC program also

includes ongoing monitoring of data entry, QA/QC reporting and data validation.

In the APEX QP's opinion there were no material QA/QC issues with respect to sample collection,

security and assaying.

Qualified Person

Edwin Naranjo Sierra

, Vice-President of Exploration for Copper Giant, is the designated Qualified

Person within the meaning of NI 43-101 and has reviewed and approved the technical information in

this news release. Mr. Naranjo holds an MSc. in Earth Sciences and is a Fellow of the Australasian

Institute of Mining and Metallurgy (FAusIMM).

About the Mocoa Porphyry System

The Mocoa project is located in the department of Putumayo, approximately 10 kilometres from the

town of Mocoa in southern

Colombia

. Copper Giant holds a district-scale land package of over

1,324 square kilometres through granted titles and applications, covering a substantial portion of the

Jurassic porphyry belt - an underexplored and highly prospective metallogenic zone in the northern

Andes.

Discovered in 1973 through a regional geochemical survey by the United Nations and the Colombian

government, Mocoa has been the subject of multiple exploration campaigns. Between 1978 and

1983, follow-up work included geological mapping, IP and magnetic geophysics, surface sampling,

drilling, and metallurgical testing. Additional drilling by B2Gold in 2008 and 2012 helped shape the

current geological understanding.

The deposit is hosted in Middle Jurassic dacite and quartz-diorite porphyries intruding andesitic to

dacitic volcanics, within

Colombia's

Central Cordillera. This 30-kilometre wide tectonic belt extends

into

Ecuador

and hosts other major porphyry systems like Mirador, Warintza,

San Carlos

, and

Panantza. Mocoa displays a classical porphyry-style alteration zonation: potassic core, sericite halo,

and outer propylitic zone, with mineralization consisting of disseminated chalcopyrite and

molybdenite, and local bornite and chalcocite, associated with stockworks and hydrothermal

breccias.

The system features over 1,000 metres of vertical continuity, overlapping hydrothermal stages, and

a broad alteration footprint. Multiple intrusive phases, brecciation events, and vein generations

suggest a dynamic magmatic-hydrothermal evolution likely driven by more than one porphyry center.

Mocoa remains open in all directions, with several satellite targets identified across the broader land

package. These features support the interpretation of a district-scale porphyry system and position

Mocoa as one of the most significant undeveloped copper-molybdenum assets in the Andes.
