Greenheart Gold intercepts 7.0 m @ 5.82 g/t Au at Igab hole D-007

Longueuil, Québec--(Newsfile Corp. - July 29, 2026) - Greenheart Gold Inc. (TSXV: GHRT) (OTCQX: GHRTF) (the "Company" or "Greenheart Gold") is pleased to report initial diamond drill and additional trenching results from its Igab project in Suriname, and to provide an update on results for the Majorodam project. Highlights The first pass drill program tested multiple target areas at Igab. Drill holes IGBD26-001 through IGBD26-012 were drilled on the Koela target, IGBD26-013 and IGBD26-014 on the Lemon Tree target, and IGBD26-015 through IGBD26-017 below the historical artisanal activities at Desiberg.

At the Koela target, drilling returned 7.0 meters (m) @ 5.82 grams per tonne of gold (g/t Au) in IGBD26-007, 8.0 m @ 2.16 g/t Au in IGBD26-003 and 4.0 m @ 4.68 g/t Au in IGBD26-011. Additional shorter Koela intervals of note include 2.4 m @ 6.42 g/t Au in IGBD26-005 and 2.0 m @ 2.58 g/t Au in IGBD26-012. Trenching at Igab continues, focused on supporting follow-up drill targeting, with significant interval highlights including 22.0 m @ 2.13 g/t Au, including 15.0 m @ 3.01 g/t Au, in IGBT26-094 at the Cannibal Creek target, and 3.0 m @ 11.59 g/t Au in IGBT26-113 at Koela East.

Greenheart Gold is currently reviewing the results from the initial drill program and additional trenches at Igab, focusing on integrating the assay results and a more detailed understanding of the geology and structure gained from the core, with programs of core relogging and structural mapping to refine target geometry and drill orientation. Results, Geological Interpretation and Follow-up at Igab, Suriname At Koela, ongoing geological work indicates that mineralization is associated with a series of northwest to southeast trending high-strain zones developed within a folded volcanic, volcaniclastic and siliciclastic rock package.
