Greenheart Gold Launches Maiden Drilling at Tosso Creek's Deep High-Grade Gold in Suriname

• Greenheart Gold has begun a 2,000-metre maiden diamond drill program at its Tosso Creek project in Suriname, following broad trench intervals at the Walaba target that included 52.0 m at 0.77 g/t Au and 7.0 m at 4.57 g/t Au.
• Tosso Creek is now the company's third active Suriname asset alongside Majorodam and Igab, and CEO Justin van der Toorn frames the multi-project structure as a deliberate way to give shareholders several separate chances at a discovery.
• Early core from Tosso Creek shows disseminated pyrite consistent with active fluid flow, and management is drilling specifically to test whether the higher-grade shoots seen in trenching (including 7.0 m at 4.57 g/t Au) continue at depth.
• Van der Toorn points to a roughly $85-million treasury as the basis for staggering work across projects rather than over-committing rigs to any single target before it is geologically ready.
• With assays still pending from Igab, Majorodam and the first Tosso Creek holes, the next re-rating catalysts for GHRT are a run of maiden results across all three Suriname projects in the coming weeks to months.

The Guiana Shield has become one of the more closely watched gold addresses in the junior exploration space over the past two years, a reputational shift owed largely to a handful of teams repeating discoveries they first made elsewhere. Greenheart Gold (TSXV:GHRT) is one of those teams: led by former Reunion Gold executives who delineated the multi-million-ounce Oko West deposit in Guyana, the company has spent the past year building a project portfolio across Suriname and Guyana. With its Tosso Creek project now under the drill bit for the first time, Crux Investor caught up with President and CEO Justin van der Toorn on site at the project's Trench 11, in the middle of the rainforest, for a look at how the program is being run.

Legacy on Project Track Records

Greenheart Gold is built on the technical legacy of Reunion Gold, whose team is best known for the discovery and delineation of the multi-million-ounce Oko West deposit in Guyana. That track record underpins Greenheart's current strategy: identify underexplored ground in the Guiana Shield, move quickly from soil geochemistry through trenching to drilling, and run several projects in parallel rather than betting everything on one target.

The company currently has three active projects in Suriname: Igab, Majorodam, and Tosso Creek. Igab and Majorodam are the more advanced of the three, sited close to existing regional operations, while Tosso Creek is a newer, more remote project that van der Toorn describes as requiring more infrastructure development to reach the same stage.

"Our approach is really simple. We want to take advantage of the fact this is a highly underexplored region in the world. We believe we've got the experience of not just success here with our former work at Reunion Gold and the discovery of Oko West's six million ounces there." 

Testing Structural Controls at Depth

At Tosso Creek, Greenheart has outlined four target areas: Maconia, Swalanga, Walaba and Sevil. A 2,000-metre diamond drilling programme has now commenced at Walaba, with drilling at Swalanga to follow. By the time of the interview, the company had completed two holes and was collaring a third, roughly 100 metres south of the initial pad, following up a trench-defined mineralised trend that extends over an estimated 1-2 km of strike length.

Trenching at Walaba has already returned some of the broadest intervals seen across Greenheart's Suriname portfolio, including 52.0 m @ 0.77 g/t Au in TOST26-021A and 23.0 m @ 0.86 g/t Au in TOST26-024. At the newer Swalanga target, roughly 1 km east of Walaba, trench TOST26-030A returned 56.0 m @ 0.97 g/T Au, including three higher-grade zones.

Van der Toorn framed the current drilling as a test of two things: whether the broad, near-surface mineralisation continues at depth below the deeply weathered saprolite, and what structural controls - lithological or cross-cutting - govern the narrower, higher-grade zones seen within that broader envelope. Early core has shown disseminated pyrite consistent with a fluid-flow system, though assay results were not yet available at the time of filming.

Portfolio Discipline: Igab and Majorodam

Greenheart's two more advanced Suriname projects, Igab and Majorodam, illustrate the company's stated approach to sequencing work across a portfolio rather than concentrating all resources on a single asset. At Igab, a maiden diamond drill programme returned 7.0 m @ 5.82 g/t Au in hole IGBD26-007 at the Koela target, alongside trench highlights including 22.0 m @ 2.13 g/T Au (including 15.0 m @ 3.01 g/t Au) at Cannibal Creek. The company is now integrating those assay results with core relogging and structural mapping to refine follow-up targeting, while crews continue surficial work on other Igab targets in parallel.

At Majorodam, a 160-hole, 11,748-metre reverse circulation programme has been completed, though roughly 35% of results remain pending because of assay laboratory delays in Paramaribo. Greenheart plans a full project review at Majorodam once the outstanding assays are in hand.

Financial Position and Capital Allocation

Van der Toorn cited a cash position of roughly $85 million following the company's recent financing, a treasury he described as giving Greenheart the ability to run multiple rigs across its portfolio without overcommitting to any single project before the geology justifies it.

"We're going to be very disciplined with the capital that we're putting into the ground. We're making sure that as much of that capital as possible is going into the ground. So, it's delivering results directly." 

That discipline extends to pacing: van der Toorn noted the company paused work on one Guyana project during the wet season and has since resumed, and that the team deliberately avoids putting more rigs on a project than its current stage of understanding supports.

The Investment Thesis for Greenheart Gold

• Greenheart is drilling a genuinely new target (Tosso Creek) for the first time, with results from the first three holes still pending, a binary near-term catalyst for the stock.
• Trench data at Tosso Creek already shows both broad tonnage-building intervals (up to 56.0 m at 0.97 g/t Au) and narrower high-grade intercepts (7.0 m at 4.57 g/t Au), a combination management says it wants to replicate with depth.
• The company is running three simultaneous Suriname projects (Tosso Creek, Majorodam, Igab), spreading discovery risk across multiple targets rather than depending on a single outcome.
• Management's stated treasury of approximately $85 million (per commentary in this interview, pending independent confirmation) gives it capacity to fund several drill programs concurrently without near-term dilution risk.
• Assay turnaround is the key operational bottleneck; investors should watch for results from the initial Tosso Creek holes, plus outstanding assays from Igab's Cannibal Creek target and roughly 35% of pending Majorodam RC results.
• The team's Reunion Gold/Oko West pedigree is a differentiator versus newer entrants to the Guiana Shield, but exploration remains high-risk and pre-resource across all of the company's projects.
• Van der Toorn indicated Tosso Creek could scale quickly from one rig to several once continuity is demonstrated, which would mark a meaningful acceleration in newsflow.

Macro Thematic Analysis

The Guiana Shield's re-emergence as an exploration destination is not accidental. It followed directly from Reunion Gold's discovery and delineation of the six-million-ounce Oko West deposit in Guyana, a find that both validated the region's prospectivity and drew a wave of new entrants seeking to replicate it. 

That framing matters for investors weighing early-stage exploration exposure broadly. Regions that have already produced one major discovery tend to attract capital and technical talent faster than genuinely frontier terrain, but they also attract competition for the best remaining ground. Greenheart's position backed by the team that made the original discovery, and holding multiple projects rather than one is a specific bet that first-mover technical knowledge of the region's structural controls translates into a repeatable edge, even as more companies stake ground nearby.

TL;DR: 

Greenheart Gold has started a 2,000 m maiden drill program at its Tosso Creek project in Suriname, following trench results including 52.0 m at 0.77 g/t Au and 7.0 m at 4.57 g/t Au at the Walaba target. CEO Justin van der Toorn says the program is designed to test whether higher-grade shoots seen at surface continue at depth, with early core showing encouraging disseminated pyrite. Tosso Creek is the company's third active Suriname project alongside Majorodam and Igab, and management says a roughly $85-million treasury lets it stagger work across all three rather than over-committing to one. Assays from the first holes are still pending.
