Gold Hart Copper Corp. Reports Drilling Results and Launches Geochemical Survey At Tolita and Nessa Complex
Gold Hart is also pleased to announce completion of the latest diamond drill hole - DDHTOL04 -at its Tolita Gold-Copper-Moly-Silver Asset in the Vicuna District of Chile. Reverse circulation drilling is now set to commence at Tolita's high-grade trench in the coming days. Gold Hart Copper has launched the first comprehensive geochemical survey at its Nessa Complex, which follows upon the success of the high grade gold and copper results obtained in the preliminary survey announced February 23, 2026. The TOLDDH01 hole was completed to a final depth of 1,051m. Drilling was halted when the rig began to slow and showed signs of mechanical strain. Although the core continued to display strong veining and remained geologically compelling, Gold Hart geologists made the strategic decision to end the hole to preserve rig integrity and ensure sufficient time to complete an additional hole before the end of the season. The Company cautions that drill core visuals may not be reliable indicators of mineralization and are therefore not to be relied upon in any meaningful way. Core recovered from TOLDDH01 exhibits classic porphyry style mineralization over an exceptionally encouraging 700m interval, marked by consistent, multi generation veining that reflects a robust hydrothermal system. Quartz veining and stockworks dominates the interval and is associated with sulfides, most commonly with argillic - phyllic alteration overprinting the potassic zones often forming well defined halos in the veins. Visible chalcopyrite occurs locally as fine disseminations, veinlets, and fracture coatings, with bornite also present, as well as occasional covellite in the 300 - 500m interval. While these copper minerals provide a clear mineralized signature, they are not present in volumes that would necessarily indicate unusually high copper grades. Nevertheless, the sheer width of the hypothesized mineralized interval is enormously encouraging for planning and vectoring future drill holes. This zonation provides an important vector for refining our geological model and guiding the placement of the next drill hole. Overall, the continuity of veining, consistent alteration, and presence of copper bearing sulfides throughout paint a highly positive picture of the system's scale and potential, adding meaningful confidence as we advance the exploration program. The TOLDDH04 hole was completed to a final depth of 551m. The hole was terminated for several reasons, primarily due to geological signals associated with the conductive structure being weaker than expected and not showing a significant change with depth. In addition, the hole began to deviate early in its inclinations, changing its dip from the planned 60° to approximately 48° by the end. While such deviations are not uncommon, this deviation increased the mechanical stress on the rig and progressively moved the hole away from the original target. Further deepening of the hole was anticipated to become technically challenging, with slower advance rates while simultaneously moving farther from the zones of interest given the drilling azimuth. Nonetheless, a total depth of more than 500m still represents a relatively deep hole and provides valuable geological information for the projects geological models. On February 23, 2026, Gold Hart announced completion of the drill hole DDHTOL01, which reached a depth of approximately 1,053m. Gold Hart anticipates commencement of this RC drill campaign in the coming days. Gold Hart is also launching its first comprehensive geochemical survey at its Nessa Complex just west of Kinross' La Coipa Gold Mine. This comprehensive geochemical survey is targeting 500-1,000 samples, primarily within the Ringo claims of the Nessa Complex. This survey follows upon the success of the preliminary geochemical survey, with several returning high grades of gold and copper. Specifically, 7 samples graded 1.25% to 4.73% copper, including 4 samples exceeding 2.40% copper. 12 Samples graded above 1g/t gold, with 6 samples grading between 4.10g/t to 9.74g/t gold. Gold Hart recently completed a preliminary geochemical survey and obtained additional high grade samples, including up to 9.7g/t gold, 968g/t silver, and 4.7% copper on surface. Gold Hart geologists - including senior geologists Professor Dr. Jose Frutos, Enrique Viteri, Jonathan Warner, and Rodrigo Diaz Tillerra - 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. Most recently, Gold Hart returned to target #1 DDHTOL01 with a more powerful drill rig and completed a 1.053km drill hole. 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 2.5km2 geophysical anomaly recently expanded by 76% to 4.5km2.
