Gold Hart drills second hole at Tolita

Mr. Isaac Maresky reports GOLD HART COPPER SECOND DRILL HOLE AT TOLITA ASSET INTERCEPTS LONG GOLD COPPER & MOLYBDENUM INTERVALS INCLUDING HIGHER GRADES THAN FIRST HOLE Gold Hart Copper Corp. has released the results of the second diamond drill hole (DDHTOL05) at its flagship Tolita gold-copper-molybdenum property in the Vicuna district of Chile. Gold Hart's second diamond drill hole again encountered long porphyry-style mineralization typical of the Vicuna 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 metres of 0.62 gram per tonne gold equivalent, including a highlight sample that included 0.60 g/t gold, 0.34 per cent copper and 20 g/t molybdenum for a gold equivalent of 0.97 g/t. This subsection was within a larger 42-metre 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 22 m of 0.40 g/t gold equivalent, within a larger 63 m mineralized intercept. Like the first hole (DDHTOL02), this second diamond drill hole (DDHTOL05) also finished in mineralization. Gold Hart geologists Jonathan Warner, PGeo, and Rodrigo Alejandro Diaz Tilleria, PGeo, 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 postmineral 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 2-D sections with drill hole projections, it is easy to lose perspective of the magnitude, but the ends of these two holes are separated by 570 m, 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 one 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, Vicuna pioneer and Tolita discoverer, noted: "After examining this drill hole -- which is now the farthest drill hole to the west from the possibly mineralized centre, 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 600 m farther away from our bulls-eye, 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 and chief executive officer of Gold Hart. Important notes: Gold equivalent grade calculated using current market prices for gold ($3,340/ounce) copper ($11,180/tonne) and molybdenum ($61,917/t) only and assumes equal recovery for all metals. These metal prices were utilized for the prior hole as well, for the sake of consistency. True widths are not yet known. Certain samples included anomalous values of silver, lead and zinc which are excluded altogether. Gold Hart Copper -- first drill hole DDHTOL02 -- announced July 22, 2025 As announced July 22, 2025, Gold Hart's first diamond hole encountered long porphyry-style mineralization typical of the Vicuna district, including near continuous gold, copper and molybdenum intercepts from approximately 137 m until the end of the drill hole at 610 m (473 m) except for a sterile zone surrounding a potentially significant fault zone of 150 m. Specifically, Gold Hart obtained 203.5 m of 0.25 g/t gold equivalent from 137.5 m, including a higher grade zone of 67 m at 0.38 g/t gold equivalent. Later in this same hole, Gold Hart intercepted another 118 m of 0.24 g/t gold equivalent, including 45.5 m at 0.30 g/t gold equivalent. The drill hole finished in mineralization. About Gold Hart Copper Corp. Gold Hart Copper is one of the largest independent land owners surrounding major miners where the famous Maricunga gold belt meets the emerging Vicuna copper belt in Chile. Gold Hart is actively acquiring, exploring and developing its portfolio of gold, copper and silver properties adjacent to the largest gold and copper assets on the continent. In addition to its large land position in the Vicuna district, Gold Hart recently acquired three properties just West on Chile's Paleocene-Eocene belt on the famous Domeyko fault, 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 six km. Gold 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. Prof. Jose 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. Gold 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 (reverse circulation) drilling, with highly encouraging results of gold, copper and silver. Gold Hart properties are controlled 100 per cent and not subject to any royalties whatsoever. Gold Hart believes it may be sitting on one of the only fully preserved untested large-scale gold-copper-silver porphyry targets in the Vicuna 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-Vicuna district's pioneering geologists in 1993. Gold Hart Copper is fully financed 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-Vicuna 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 (5,600 metres/5.6 kilometres) with the highest-grade trench returning grades up to 52 g/t gold equivalent including 4 per cent copper. Tolita has undergone helicopter mag surveys which identified four unique anomalies as well. In 1996, a third party company optioned the property and drilled three short 200 m RC holes, without any geophysics and yet still hit gold and copper in all three holes, including long intercepts of gold and copper (150 m and 164 m, respectively) close to surface in two of the three holes. At the time, gold was approximately $300/oz and copper traded below $1.00/pound, and large-scale sulphide/porphyry deposits with both gold and copper were often considered less favourable than smaller-scale gold-only oxide deposits. As a result, and due to general market sentiment for junior exploration companies in 1997 to 1998, Tolita was only drilled to a depth of 200 m with three short RC holes (out of a planned eight-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 2.5 square km 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 financed for this planned campaign.
