Gold Hart upsizes financing to $10M to $15M

Executive Summary

• Gold Hart Copper Corp. is upsizing its concurrent financing related to the acquisition of Rhyolite Resources Ltd., increasing the target from a maximum of $10 million to approximately $10–$15 million due to strong investor demand.
• The company is advancing exploration across its Chilean portfolio, specifically Tolita, where it is completing a deep diamond drill hole expected to exceed 1 km, and initiating a new Reverse Circulation (RC) drill campaign at high-grade surface trenches in early March.
• Significant exploration updates were provided for the Nessa complex, including a 330% land expansion to 13,500 hectares and new high-grade geochemical samples, alongside planned exploration activities for Toro, Zelma, and Casale Sur/Cachitos.

Key Details

• Financing Update:
  • Original announcement (Feb 17, 2026) specified a financing of $4 million to $10 million concurrent with the Rhyolite Resources acquisition.
  • Current intent is to upsize the financing to close on approximately $10 million to a maximum of $15 million.
  • Investor demand has been reported as "well in excess" of the $15 million cap.
  • Proceeds will accelerate exploration at the company's portfolio of properties.
• Tolita Property (Vicuna District):
  • Drilling: Completed two diamond drill holes (~600 m each) confirming a porphyry system with intercepts of 360 m and 231 m of gold, copper, and molybdenum mineralization.
  • Active Drilling: Currently completing the deepest drill hole yet, expected to exceed 1,000 meters.
  • New RC Campaign: Adding an RC drill rig to Tolita’s highest-grade trench (up to 52 g/t gold equivalent, including 3.99% copper) within 10 meters of 8.61 g/t gold. Rig expected on site by early March to test high-grade shallow components.
  • Historic Data: 5,600 m of trenching with nine long trenches averaging 95 m each at 0.21 g/t Au (up to 1.71 g/t Au).
  • Geophysics: IP anomaly expanded by 76% to 4.5 square kilometers.
• Nessa Complex (Domeyko Fault System):
  • Land Expansion: Expanded by 330% from 4,100 hectares to 13,500 hectares (135 sq km).
  • Geochemistry: Follow-on survey yielded samples up to 9.7 g/t Au, 968 g/t Ag, and copper samples exceeding 5,000 ppm. Historic pits showed up to 25 g/t Au, 3.25% Cu, and 958 g/t Ag.
  • Future Plans: Planning a 500–1,000 sample geochemical survey, followed by trenching and geophysics. Aiming to have a drill rig on site this year, likely using RC drilling.
• Other Properties:
  • Toro: Six historic holes intercepted gold and silver; potential for low-to-moderate sulphidation epithermal system. Company plans to add a drill rig with additional funds.
  • Zelma: Surrounded by Barrick/Newmont’s Norte Abierto JV. Received preliminary geochemical survey with anomalous Au, Cu, and Mo values.
  • Casale Sur & Cachitos: Casale Sur added via government auction adjacent to Cachitos. Dr. Frutos believes potential for a porphyry undercover exists. Budget allocated for exploration.
• Acquisition Context:
  • Gold Hart Copper signed an agreement to acquire Rhyolite Resources Ltd. concurrent with the financing.

Notable Quotes

• Rodrigo Diaz Tilleria, Vice-President: "Our focus remains the large-scale porphyry potential of Tolita. But Tolita also offers the rare opportunity to target and hopefully prove a high-grade shallower component of the asset... RC drilling is significantly faster and cheaper, does not require water to operate, and is well suited to the characteristics of this target."
• Third-Party Geophysicist: "The vertical extent of the steeply dipping conductor... is better defined on the two new deep lines... This would indicate to me, that the probable structure extends very deeply... Hopefully, the copper and gold grades would increase correspondingly as well."
