Greenheart Gold Starts Diamond Drilling at Tosso Creek
Greenheart Gold Inc. has commenced an initial 2,000-metre diamond drilling program at the Tosso Creek Project in Suriname, targeting structural controls and depth continuity beneath recent high-grade trench intersections across the property.
The initial drilling is underway at the Walaba target within the 96-square-kilometre project area, with subsequent drilling planned at the Swalanga target located approximately one kilometre to the east. Recent trenching at Walaba returned broad intervals including 52.0 metres grading 0.77 grams per tonne of gold in trench TOST26-021A, which included 4.0 metres at 1.68 grams per tonne of gold and 6.0 metres at 1.29 grams per tonne of gold. Additional trenching at Walaba in TOST26-024 intersected 7.0 metres at 4.57 grams per tonne of gold, including 4.0 metres at 7.89 grams per tonne of gold, alongside a 23.0-metre interval grading 0.86 grams per tonne of gold. Meanwhile, trenching at the recently identified Swalanga target returned 56.0 metres grading 0.97 grams per tonne of gold, including 11.0 metres at 1.53 grams per tonne of gold, 8.0 metres at 1.25 grams per tonne of gold, and 16.0 metres at 1.01 grams per tonne of gold.

When Greenheart Gold acquired an option to secure a 100% interest in the Tosso Creek Project in February 2025, exploration across the property was restricted to initial geochemical soil surveys. The project has since advanced from those early reconnaissance efforts to active continuous trench sampling and the current 2,000-metre diamond drilling program.
Assay results remain pending for additional trenching completed to the north and south of the Swalanga target. The data gathered from the ongoing drilling program will provide essential geological and structural information to guide subsequent drill planning across the property’s identified target zones.
The active work at Tosso Creek forms part of the company's broader exploration pipeline in the Guiana Shield. The ongoing operations in Suriname follow recent exploration milestones across the company's regional portfolio, including maiden drill results from the Igab gold project that returned 7.0 metres at 5.82 grams per tonne of gold at the Koela target.
