Greenheart Gold Commences Initial Diamond Drill Program at the Tosso Creek Project, Suriname, Targeting Below Recent Trench Results That Include Intervals of 56.0 M @ 0.97 g/t Au and 7.0 M @ 4.57 g/t Au

Greenheart Gold starts drilling at Tosso Creek, reporting promising trench gold grades.

What the company is saying

Greenheart Gold Inc. announces the start of a 2,000-meter diamond drilling campaign at its Tosso Creek Project, initially targeting Walaba and then Swalanga. The company highlights trench results at Walaba, such as 52.0 meters at 0.77 g/t gold and a higher-grade interval of 7.0 meters at 4.57 g/t gold, aiming to demonstrate the project's mineralization potential. At Swalanga, a new trench yielded 56.0 meters at 0.97 g/t gold, with several higher-grade sub-intervals. The narrative emphasizes technical rigor, referencing continuous sampling, QA/QC procedures, and review by President and CEO Justin van der Toorn, a Qualified Person under NI 43-101. Forward-looking statements focus on evaluating structural controls, continuity of mineralization, and informing future drill planning. The tone is measured and technical, with confidence grounded in assay results and adherence to regulatory standards.

What the data suggests

Disclosed trench results at Walaba and Swalanga show broad mineralized zones, with intervals such as 52.0 meters at 0.77 g/t gold and 56.0 meters at 0.97 g/t gold, alongside shorter, higher-grade sections. Sampling followed defined protocols, with intervals calculated using explicit grade cut-offs and internal waste limits, and QA/QC controls applied at a 5% rate. The 2,000-meter drilling program is underway, but no drill results are yet available. The data supports the presence of near-surface gold mineralization but does not establish resource size, continuity at depth, or economic viability. No financial data, cost disclosures, or comparative performance metrics are included. The technical disclosure is detailed, but the absence of financials or resource estimates limits the ability to assess project scale or value.

Analysis

The announcement is generally proportionate in tone, focusing on the commencement of a 2,000 m drilling program and reporting specific trench assay results. Most claims are factual and supported by disclosed numerical data, such as trench intervals and grades. Forward-looking statements are present but are limited to the intended objectives of the drilling program and pending assay results, rather than aspirational production or financial targets. There is no evidence of exaggerated language or narrative inflation; the technical results are presented with appropriate context and caveats. However, the absence of any financial or profitability metrics means the true investment signal cannot be rated above weak_positive, as per the disclosure completeness rule. The capital outlay for the drilling program is not characterized as large, and no long-dated, uncertain returns are promoted.

Risk flags

• ●Operational risk is high at this stage, as the drilling program is only just commencing and mineralization continuity, grade, and extent remain untested at depth. Trench results alone do not guarantee subsurface resource potential.
• ●Disclosure risk is present due to the lack of any financial data, cost breakdowns, or funding updates, making it impossible to assess whether the company can sustain ongoing exploration or manage capital requirements.
• ●Exploration risk remains significant, as the project is early-stage with no resource estimate, and the economic viability of the mineralization is unknown. The results are promising but not yet indicative of a mineable deposit.

Bottom line

This announcement signals early-stage exploration progress at Tosso Creek, with trench assays indicating potentially meaningful gold mineralization at Walaba and Swalanga. The technical data is specific and credible, but the absence of drill results, resource estimates, or financial disclosures means the investment case remains speculative. No evidence is provided on funding sufficiency or cost structure, so investors cannot gauge the company's ability to advance the project without further dilution or financing. The most important takeaway is that Greenheart Gold has moved from surface sampling to drilling, but the project's value will hinge on forthcoming drill results and eventual resource definition. Investors should expect further updates on assay results and drilling progress before any investment thesis can be substantiated.

Announcement summary

(TSXV: GHRT) (OTCQX: GHRTF) Greenheart Gold Inc. has commenced a 2,000 meters (m) diamond drilling program at its Tosso Creek Project in Suriname, starting at the Walaba target with drilling at the Swalanga target to follow. Trench results at Walaba include 52.0 m @ 0.77 grams per tonne of gold (g/t Au) in TOST26-021A, including 4.0 m @ 1.68 g/t Au and 6.0 m @ 1.29 g/t Au. Trench TOST26-024 at Walaba intersected 7.0 m @ 4.57 g/t Au (including 4.0 m @ 7.89 g/t Au), and 23.0 m @ 0.86 g/t Au (including 5.0 m @ 2.79 g/t Au). At the Swalanga target, trench TOST26-030A returned 56.0 m @ 0.97 g/t Au, including 11.0 m @ 1.53 g/t Au, 8.0 m @ 1.25 g/t Au and 16.0 m @ 1.01 g/t Au. Additional trenching has been completed at Swalanga, with assay results pending over much of the sampled lengths. The results from this trenching program will be used to assess the continuity of mineralization over a strike length of approximately 900 m. All scientific and technical information in this press release has been reviewed and approved by Justin van der Toorn, President and CEO of Greenheart Gold, and a Qualified Person under Canadian National Instrument 43-101.
