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
