Toronto, Ontario--(Newsfile Corp. - February 2, 2026) - Gold Hart Copper Corp. (TSXV: HART)

(the "Company", "Gold Hart", or "HART") is pleased to announce positive results from its recent

geochemical survey at the Nessa gold silver copper complex just west of Kinross' La Coipa Gold

Mine, which returned high grades of gold, copper, and silver.

Gold Hart is also pleased to provide an update on the drilling currently underway at the

Company's flagship Tolita gold copper molybdenum silver asset in the emerging Vicuña Copper-

Gold District of Chile.

Nessa Gold Copper Silver Complex - Geochemical Survey Results - Confirming High Grades &

Mining Pits

Gold Hart Copper recently (Jan. 22, 2026) announced a significant expansion of the Nessa gold

copper silver complex by approximately 3.3X from an initial property size of 4,100Ha up to a

current land position of 13,500Ha (135km). As prior disclosed, Gold Hart completed a follow-on

geochemical survey at Nessa to test certain areas of interest.

After reviewing historic information from several high priority areas each containing high grade

samples and clusters of old mining pits the Gold Hart geology team developed a program aimed

at comprehending the known geochemical footprint of these workings, mapping pit geology,

ground truthing their locations, and verifying the grades reported in historical samples. Satellite

imagery analysis also identified additional undocumented historic mining pits across the property.

An additional objective was to investigate these new zones to begin to understand their extent

and relevance to the system. Please refer to the notes regarding quality assurance and quality

control measures applied during the execution of the work being reported on, at the end of this

disclosure.

Therefore, the primary purpose of this Nessa geochemical survey was to confirm the presence

of high grades and better understand the factors that led to such a widespread distribution of

mining pits throughout the property.

Gold Hart is very pleased to report that the lab results included high grades for gold, copper, and

silver. Specifically, 12 of 51 samples contained at least 1g/t gold, with 6 samples containing at

least 4g/t, and 2 exceeding 9g/t gold. In terms of silver, 4 samples contained at least 100g/t.

Interestingly, 12 samples returned at least 3000ppm copper with 9 containing in excess of

5,000ppm copper (">5000ppm Cu"). The Company has requested re-analyzing of these high

grade copper samples to determine exact values, and hopes to be in a position to report on the

final values in the coming week.

Highlighted areas and a chart of the top 50% of samples taken, are displayed herein:

The Nessa Complex is just west of Kinross' La Coipa Gold Mine, and just south of the massive

Codelco El Salvador - Potrerillos copper mining and smelting complex, one of the oldest copper

smelting facilities in the country. Nessa is also surrounded by major miners Newmont, Solaris, JX

Nippon, and Anglo American, and sits just northwest of the new Rio2 - Fenix Gold Mine.

Tolita Drill Update - Drill at 900m & Remains in System of Interest

Gold Hart Copper is also pleased to provide an update on drilling at the Company's flagship Tolita

gold-copper-molybdenum-silver asset in the Vicuña District of Chile. The drill has reached a

depth of 900m and from a geological perspective, Gold Hart's preliminary interpretation is that

the hole remains within the mineralized system of interest. The core continues to display

encouraging characteristics, with multiple intervals showing strong hydrothermal alterations and

mineralization consistent with a fertile porphyry-style environment.

Recently, Gold Hart geologists observed core intervals containing several veins with pyrite,

chalcopyrite, bornite, and covellite. Such observations continue to support further deepening

of the hole.

Gold Hart recently hosted a site visit which included tours of the Tolita & Nessa assets. Gold Hart

board and advisory board members including the honourable John R. Baird, Mark Kucher, and

Aleta Shiff were also in attendance. In this 360-degree immersive video -Gold Hart co-founder

Additional RC Drill Rig at Tolita to Target High Grade Trench Up to 52g/t Gold Equivalent with

4% Copper

As prior announced (Jan. 22, 2026), in addition to Gold Hart's primary diamond drilling at Tolita,

the Company is planning to add a reverse circulation (RC) drill rig in order to target certain higher

grade opportunities closer to surface at Tolita. Specifically, Gold Hart intends to target its highest

grade trench, which grades 8.61g/t gold equivalent over 10m, including 2m at 10.40g/t gold, 20g/t

silver, and 2.88% copper, and including grabs of 45.75g/t gold, 28g/t silver, and 3.99% copper

(approximately 52g/t gold equivalent).

Gold Hart recently opened up this high-grade trench with a bulldozer and exposed visible green

and turquoise staining typical of copper minerals malachite and chrysocolla. Interestingly, the

larger geophysical anomaly at Tolita appears to reach surface at or near this high-grade trench.

Gold Hart Vice President Rodrigo Díaz Tillería (P.Geo) commented, "Our focus remains the large-

scale porphyry potential of Tolita. But Tolita also offers the rare opportunity to target and

hopefully prove a high-grade shallower component of the asset. In the Vicuña District where 1g/t

gold on surface is rare, we have 52g/t gold and simply put we need to test it. RC drilling is

significantly faster and cheaper, does not require water to operate, and is well suited to the

characteristics of this target. Our current geological model assumes that this high-grade trench at

Tolita may only be a fraction of the size of the larger system, but we do believe it hosts potential

for generating higher grade intercepts close to surface and therefore potential to add high grade

ounces, thereby demonstrating another facet of the Tolita asset."

Tolita - Flagship Gold Copper Moly Silver Porphyry Target in Vicuña District - Diamond Drilling

Program

Gold Hart geologists - including senior geologists Professor Dr. Jose Frutos, Enrique Viteri,

Jonathan Warner, and Rodrigo Diaz Tillería - carefully designed a 10-hole drill plan in order to

optimally test Tolita as a potential gold-copper-molybdenum-silver porphyry target. As prior

announced, Gold Hart first attempted to drill target #1 known as DDHTOL01 in March of 2025, but

after difficulties were encountered under tight time constraints, the team instead elected to drill

DDHTOL02 and DDHTOL05. These holes were approximately 600m each and encountered

approximately 360m and 230m of gold, copper, and moly porphyry mineralization, respectively.

Now, Gold Hart is back to target #1 DDHTOL01 with a more powerful drill rig capable of reaching

1,100-1,200m.

Consequently, there await at least another seven highly attractive diamond drill targets identified

across the asset area. These targets are supported by a combination of geophysical

characteristics, including chargeability and conductivity, strong geological and structural controls

as well as coincident geochemical anomalies.

Tolita is a very large target, with an original 2.5km geophysical anomaly recently expanded by

76% to 4.5km.The Tolita gold soil sample geochemical surface halo (an approximation of gold on

surface above 0.1g/t) alone is nearly 28Ha and the Tolita property is 3,476Ha equal to

approximately 34.8km.

Furthermore, as recently confirmed in a follow-up geophysical survey, the Tolita geophysical

anomaly expands in both size and intensity at depth, which could translate into an enlarging

system at depth. Per the third party geophysicist who conducted the survey, ""The vertical extent

of the steeply dipping conductor that is likely related to a fault is better defined on the two new

deep lines (2600N and 452200E). This surprised me, as I had expected resolution similar to the

first lines. This would indicate to me, that the probable structure extends very deeply and has a

strong contrast in resistivity with the host rock. Because it is conductive, it should act as good

conduit for hydrothermal water flow, which should be good news for mineralization. There is

confirmation that the alteration system extends to greater depth and may increase in intensity at

depth as it is more conductive. Hopefully, the copper and gold grades would increase

correspondingly as well."

Porphyry systems in Chile, and in the Vicuña District specifically, can prove larger and richer as

they progress deeper. For example, in Chile, Atex Resources announced one of their most

significant drill holes ever (ATXD25C) which graded 2.72% copper equivalent, beginning at

1,558m and ending at a depth of 1,722m. In the Vicuña District, NGEX published "DPDH028, the

best hole drilled to date as Lunahuasi, which was drilled deeper and to the west of all previous

holes", which included multiple highly compelling intercept including the deepest 53.5m (1,219.5m

- 1,273.0m) grading 7.79% copper equivalent. In summary, the Company remains extremely

optimistic about this current drill hole DDHTOL01, in addition to the future diamond drill targets as

well.

Additional Information on Nessa Gold Copper Silver Complex - Geochemical Survey & Next

Steps

The dataset for the Nessa Complex highlighted the need for a comprehensive geological

sampling and mapping campaign. Gold Hart geologists focused on revisiting historic mining pits

at Nessa as well as those visible via satellite imagery, in addition to other points of interest.

Gold Hart geologists interpret the results as extremely encouraging, as Gold Hart successfully

confirmed the presence of high grades. Several samples returned grades between 4-9.7 g/t gold,

further reinforcing the high grade nature of the system. In addition, multiple copper and silver

assays exceeded the laboratory detection limits (>0.5% Cu and >400 g/t Ag), and pulps from

these samples are currently being re-analyzed to obtain precise values. The Gold Hart geology

team also identified multiple vein systems displaying consistent structural trends, providing

valuable insight that is already guiding the early stages of target generation for the next

exploration campaign.

Building on the positive results from this campaign, the next phase of work across the broader

Nessa regional property will focus on significantly advancing access, geochemical coverage, and

subsurface understanding. A systematic soil sampling program will be expanded across the

property to establish a continuous geochemical dataset capable of identifying new anomalies and

refining existing ones. These results will guide a series of targeted trenching programs designed

to expose mineralized structures, validate geochemical trends, and provide critical geological

context.

To complement surface work, a combination of induced polarization (IP) and magnetic surveys

will be deployed to map subsurface chargeability, resistivity, and structural features. These

geophysical datasets will help delineate potential mineralized zones at depth and integrate with

geochemical and geological information to refine drill targeting. The culmination of this regional

program will be a reverse circulation (RC) drilling campaign aimed at testing the highest priority

targets generated from the combined soil, trenching, and geophysical results. The drilling phase

will mark a major step forward in evaluating the district scale potential of the Nessa Complex.

About Gold Hart Copper's Tolita Gold-Copper-Molybdenum-Silver Target

The Tolita property is a historically significant gold-copper asset which was first recognized and

staked in 1993 - by one of the pioneering geologists of the Maricunga-Vicuña district - for its

uniquely high grades of gold and copper on surface. Geochemical surveys revealed gold,

copper, silver, and molybdenum anomalies, which led to trenching. Tolita has had significant

trenching (5,600m / 5.6km) with the highest grade trench returning grades up to 52g/t gold

equivalent including 4% copper. Tolita has undergone helicopter mag surveys which identified 4

unique anomalies as well.

In 1996, a third party company optioned the property and drilled 3 short 200m RC holes, without

any geophysics, and yet still hit gold and copper in all 3 holes, including long intercepts of gold

and copper (150m and 164m, respectively) close to surface in 2 of the 3 holes. At the time, gold

was approximately $300/oz and copper traded below $1.00/lb, and large scale sulphide porphyry

deposits with both gold and copper were often considered less favorable than smaller scale gold-

only oxide deposits. As a result, and due to general market sentiment for junior exploration
