Toronto, Ontario--(Newsfile Corp. - July 22, 2025) - Gold Hart Copper Corp. (TSXV: HART) (the
"Company", "Gold Hart", or "HART") is pleased to announce the results of the first diamond drill
hole (DDHTOL02) at its flagship Tolita gold-copper-molybdenum property in the Vicuña District of
Chile.
Gold Hart's first diamond hole encountered long porphyry-style mineralization typical of the
Vicuña District, including near continuous gold, copper, and molybdenum intercepts from
approximately 137m until the end of the drill hole at 610m (473m) except for a sterile zone
surrounding a potentially significant fault zone of 150m.
Specifically, Gold Hart intercepted 203.5m of 0.25g/t gold equivalent from 137.5m, including a
higher grade zone of 67m at 0.38g/t gold equivalent. Later in this same hole, Gold Hart
intercepted another 118m of 0.24g/t gold equivalent, including 45.5m at 0.30g/t gold equivalent.
The drill hole finished in mineralization.
Enrique Viter-Aldunate, Vicuña pioneer and Tolita discoverer commented, "I could not be happier
with the first drill hole at Tolita, as 320m+ of 0.24-0.25g/t is highly indicative of a potentially very
large gold system. I recall from my personal experience drilling Cerro Casale that the first several
holes did not return such an extensive and continuous presence of gold, and of course that asset
has now become the largest gold-copper deposit on the continent. In fact, from around 130m to
the end of the hole at 610m (nearly 480m), it would appear that there is nearly consistent
mineralization except for the 150m sterile zone which we now believe to be a major geological
fault. This drill hole has also significantly advanced our geological understanding of the asset, as
Dr. Professor Jose Frutos and I now both strongly believe that this fault may have caused the
higher-chargeability and higher-conductivity anomaly to land closer to surface on the eastern
side of the property, which could potentially host higher grades. I believe this first hole
(DDHTOL02) should lay to rest any questions around whether or not Tolita has potential to be a
porphyry, because the drill hole clearly proves we intercepted porphyry-style mineralization
typical of the Vicuña. Like this first diamond drill hole, all historic RC holes were also drilled into
the western side of Tolita; so the eastern side remains completely untested, and drilling the near-
surface high-chargeability high-conductivity zone must be priority number one, as was our
original plan with DDHTOL01. I am extremely excited about the future as Gold Hart advances
further drilling particularly on the eastern side of the asset."
"We are thrilled to have encountered such long intervals of gold, copper, and molybdenum
particularly so early on in our first drill hole ever at Tolita," stated Isaac Maresky, Co-founder &
CEO of Gold Hart. "I am more excited than ever about the potential of Tolita and to continue the
drill campaign in September. Now that we have been fortunate enough to return porphyry-style
intercepts so early, with good correlation between geophysical anomalies and gold-copper-
molybdenum, we can focus on honing in on the top-tier drill targets where we might find grades.
Interestingly, the eastern side of the property - totally open and untested - is exactly where the
chargeable geophysical anomaly is highest and also where the highest conductive zone overlaps
as well."
Note: For the purposes of calculating gold equivalent, the following metal prices were utilized:
Gold: $3,340.20/oz Copper: $11,180/t Molybdenum: $61,917/t

Gold Hart hopes to be in a position to report on the results from the second and final hole
(DDHTOL05) from its recent ~1,200m campaign in the coming two weeks.

About Gold Hart Copper
Gold Hart Copper is one of the largest independent land owners surrounding major miners where
the famous Maricunga Gold Belt meets the emerging Vicuña Copper Belt in Chile. HART is
actively acquiring, exploring and developing its portfolio of gold, copper & silver properties
adjacent to the largest gold and copper assets on the continent.
In addition to its large land position in the Vicuña District, Gold Hart recently acquired three
properties just West on Chile's Paleocene-Eocene Belt on the famous Domeyko Faul, which is
home to some of Chile's largest gold, copper, and silver assets including Escondida,
Chuquicamata and Collahuasi. The new Gold Hart properties host several historic gold and
copper mines with high grades of gold, copper, and silver on surface, with a large alteration and
magnetic anomaly extending approximately 6km.
HART's team of geologists were personally involved in pioneering exploration in the region,
leading to some of its greatest gold, copper, and silver deposits, and include the country's former
Geological Survey National Deputy Manager Dr. Professor José Frutos. Specifically, senior Gold
Hart geologists were personally involved in the Escondida copper discovery, now the largest
copper mine in the world controlled by Rio Tinto and BHP, as well as Cerro Casale, the largest
gold-copper discovery in Chile acquired by Barrick and Newmont (GoldCorp) with 59-million
ounces of gold and 12.5-billion pounds of copper.
HART has rolled-up a portfolio of historically significant assets surrounding majors, in some cases
personally staked by the very same geologists who made the adjacent mega-discoveries, since
the early 1990s. Some of the Gold Hart properties have already undergone a first phase of RC
drilling, with highly encouraging results of gold, copper, and silver. Gold Hart properties are
controlled 100% and not subject to any royalties whatsoever.
HART believes it may be sitting on one of the only fully-preserved untested large-scale gold-
copper-silver porphyry targets in the Vicuña District - an asset that was first recognized for its
uniquely high grades of gold and copper on surface - and staked by one of the Maricunga-Vicuña
district's pioneering geologists in 1993. Gold Hart Copper is fully funded for its planned drill
campaign.

About Gold Hart Copper's Tolita Gold-Copper-Silver-Molybdenum Target
The Tolita property is a historically significant gold-copper-molybdenum 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 companies in 1997-1998, Tolita was only drilled to a depth of 200m with 3 short RC
holes (out of a planned 8 hole campaign).
When Gold Hart acquired the property, a full geophysical survey was conducted by a recognized
geophysics firm, and a large high-chargeability and conductive anomaly was discovered that is
near surface and almost 2.5km in size and "interpreted as a copper-gold or gold-copper
porphyry system that certainly warrants additional exploration and drilling". Gold Hart Copper
has therefore launched diamond drilling and is fully funded for this planned campaign.
