Toronto, Ontario--(Newsfile Corp. - August 6, 2025) - Gold Hart Copper Corp. (TSXV: HART) (the

"Company", "Gold Hart", or "HART") is pleased to announce the results of the second diamond

drill hole (DDHTOL05) at its flagship Tolita gold-copper-molybdenum property in the Vicuña

District of Chile.

Gold Hart's second diamond drill hole again encountered long porphyry-style mineralization

typical of the Vicuña District, with certain drill intervals showing higher grades of gold, copper,

and molybdenum relative to the first hole announced last month.

Specifically, Gold Hart intercepted 10 meters of 0.62g/t gold equivalent, including a highlight

sample that included 0.60g/t gold, 0.34% copper, and 20g/t molybdenum for a gold equivalent

of 0.97g/t. This subsection was within a larger 42m mineralized intercept.

This aforementioned intercept was above the fault, but similar to the first hole, Gold Hart again

encountered gold, copper, and molybdenum mineralization below the fault later in the hole as

well. In this case, below the fault, Gold Hart intercepted 22m of 0.40g/t gold equivalent, within a

larger 63m mineralized intercept.

Like the first hole (DDHTOL02), this second diamond drill hole (DDHTOL05) also finished in

mineralization.

Gold Hart geologists Jonathan Warner, P.Geo and Rodrigo Alejandro Díaz Tillería, P.Geo,

commented, "It is highly encouraging to continue seeing gold, copper, and molybdenum

anomalies coinciding with zones of conductivity and chargeability. Once again, we observed a

sterile interval cutting across two mineralized sections, clearly associated with a major structure

or post-mineral zone, an important input for optimally modelling and developing the asset as we

hope to vector towards a higher grade core. A critical finding is that DDHTOL05, like the first hole

(DDHTOL02), finished in mineralization, reinforcing that the system remains completely open at

depth. When reviewing the 2D sections with drillhole projections, it is easy to lose perspective of

the magnitude, but the ends of these two holes are separated by 570m, a highly significant

distance for evaluating the lateral continuity potential of the system. Right now we know this

system remains open at depth, and based on regional experience, porphyry systems of this type

can extend between 1 and 1.5 km. In addition, the consistent metal presence in holes 570 m apart

provides strong evidence not just for vertical continuity, but for lateral continuity of the system as

well."

Enrique Viteri-Aldunate, Vicuña pioneer and Tolita discoverer, noted, "After examining this drill

hole - which is now the farthest drill hole to the west from the possibly mineralized center, which

appears to be potentially located to the east - there is sufficient gold to indicate that we are within

an environment of gold mineralization, which is very positive for exploration. This drill hole is

clearly indicative of gold in the hydrothermal system. Now we have to find the core."

"Based upon our current geological thesis, this second hole moved nearly 600m farther away

from our bullseye, and not only did we once again obtain nice long porphyry-style intercepts of

gold, copper, and molybdenum, not only did the hole again finish in mineralization, but in this case

we actually saw some higher grade intervals than the first hole," added Isaac Maresky, Co-

founder & CEO of Gold Hart.
