Gold Hart to restart drilling at Tolita asset

Mr. Isaac Maresky reports GOLD HART COPPER TO RECOMMENCE DRILLING AT TOLITA GOLD-COPPER-MOLYBDENUM ASSET IN VICUÑA DISTRICT OF Chile Gold Hart Copper Corp. has released plans for the third phase of drilling at its flagship Tolita gold-copper-molybdenum asset in the Vicuna district of Chile. Tolita was originally drilled down to a shallow depth of approximately 200 metres using an RC (reverse circulation) drill in the late 1990s, with all three holes encountering gold and copper. Earlier this year, Gold Hart tripled that depth with two diamond drill holes which reached approximately 600 metres each, both encountering porphyry-style gold, copper and molybdenum mineralization. Now, Gold Hart believes it will be able to potentially nearly double that 600 m depth. Specifically, the company has secured a Boart Longyear LF 90D diamond drill rig, rated to a depth capacity maximum of 1,193 metres. It is anticipated that the drill will be mobilized within the next week, with drilling to officially recommence a week thereafter. Gold Hart geologists hope to drill at a rate of approximately 700 to 900 m per month. "We truly believe we've barely scratched the surface at Tolita relative to its potential. Both diamond holes drilled to date encountered porphyry-style gold, copper and molybdenum intercepts, and all three historic RC holes intercepted gold and copper, but these assets can host very large systems and extend significantly deeper -- and Tolita remains completely open. Hart senior geologists are extremely excited about our ability to return to target No. 1 equipped with a rig able to drill four times deeper than the historic RC holes and two times deeper than even the recent diamond drill holes," commented Isaac B. Maresky, co-founder and chief executive officer of Gold Hart. The company also wishes to announce that an additional geophysical survey may be conducted at Tolita sometime after commencement of drilling. The company has been in active consultation with its contracted geophysics firm, which has developed a specialized expertise having completed nearly 1,000 geophysical surveys for 100s of companies in Chile, including Atex Resources Inc. Geophysical chargeability surveys tend to recognize the top of the horizon of the sulphides, hence Gold Hart's first priority drill targets will remain unchanged given the shallowness of the anomaly east of the fault. However, there are certain areas of Tolita which may be amenable to additional geophysical testing. For example, the Tolita geophysical anomaly remains open to the north; and west of the inferred fault contains lower chargeability which may prove amenable to deeper geophysics if the system is indeed deeper on that side of the asset. The company will provide an update on this initiative in due course. Gold Hart Copper -- first diamond drill hole DDHTOL02 -- announced July 22, 2025 Gold Hart's first diamond hole (DDHTOL02) 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 gram per tonne 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. Gold Hart Copper -- second diamond drill hole DDHTOL05 -- announced Aug. 6, 2025 Gold Hart's second diamond hole (DDHTOL05) once again intercepted porphyry-style intercepts of gold, copper and mineralization, including certain areas of higher grade relative to the first hole. Specifically, Gold Hart intercepted 10 metres of 0.62 g/t 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 m 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. Important notes: Gold equivalent grade calculated using prices for gold ($3,340/oz) copper ($11,180/t) and molybdenum ($61,917/t) only, and assumes equal recovery for all metals. These metal prices were utilized for both diamond drill holes 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. 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. 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 kilometres. 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. 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 per cent 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 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 m/5.6 km) 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.
