Greenheart Gold (TSXV:GHRT) is executing a comprehensive exploration strategy across the Guiana Shield, with President and CEO Justin van der Toorn outlining the company's progress on multiple high-potential gold projects in Suriname and Guyana. The company's disciplined approach to early-stage exploration, combined with an experienced management team and strategic portfolio management, positions it to make discoveries in one of the world's most underexplored yet geologically prospective gold regions.

Capital Discipline Drives Portfolio Management

Greenheart's operational philosophy centers on aggressive exploration of high-potential ground while maintaining the financial flexibility to drop non-performing assets. In 2025, the company streamlined its portfolio by relinquishing several projects in Guyana while adding the Gold Hill project, an early-stage opportunity showing significant artisanal mining activity. This approach reflects the strategy established from the company's inception: explore aggressively, move quickly to drill decisions, and maintain sufficient capital to withstand project failures without compromising the overall exploration program.

"The strategy from day one was always to have the capital balance and to not really have to worry too much about projects falling over."

The company currently operates three projects in Suriname - Majorodam, Igab, and Tosso Creek - each at different stages of advancement, allowing for continuous newsflow and reduced project-specific risk.

Majorodam RC Program Tests 15-Kilometer Gold Anomaly

The most advanced project in Greenheart's portfolio is Majorodam in Suriname, where a 10,000-meter reverse circulation (RC) drilling program is currently underway. The project features a 15-kilometer-long gold-in-soil anomaly running parallel to a basement contact within volcanic and sedimentary rocks. Diamond drilling conducted in 2025 established structural controls on mineralisation, identifying higher-grade shoots plunging steeply to the south within a north-south deformation zone characterised by extensive shearing.

The shift to RC drilling represents a strategic decision to rapidly test the entire anomalous trend at lower cost - approximately 50-60% of diamond drilling expenses. The program will drill relatively shallow holes, typically 100 meters or less, to define near-surface mineralisation before following higher-grade zones to depth with diamond drilling. RC drilling provides rapid turnaround on assay results without the structural detail of core, making it an effective tool for covering large areas and identifying targets for more detailed follow-up work.

Majorodam benefits from proximity to existing operations, including Newmont's Saramacca deposit located just two kilometers from Greenheart's Gowtu target in the northwestern part of the property. This proximity provides valuable geological context, as Saramacca represents a shear zone-hosted system between contrasting lithological units - a geological setting that Greenheart is targeting along the curving trend from northwest to southwest orientation at Majorodam.

Igab: High-Grade Shear Zones Drive Diamond Drilling Campaign

The Igab project in eastern Suriname, located 30 kilometers south of Newmont's Merian operation, has emerged as a high-priority target following exceptional trenching results. The project contains approximately five distinct soil anomalies, with the Koela East and Koela West targets returning particularly strong intercepts: 12 meters at 4.82 g/t gold at Koela East and 11 meters at 9 g/t at Koela West. These high-grade shear zones represent quartz vein-hosted mineralisation with clear structural controls visible in surface exposures.

A diamond drilling program is scheduled to commence in early April 2026, with the rig currently being mobilised. Unlike Majorodam, where RC drilling will provide broad coverage, Igab will utilise diamond drilling from the outset to establish detailed structural understanding early in the exploration process. 

"We think it's very important to get the structural understanding early on in the exploration phase so we can understand where the controls and mineralisation might be." 

The geological setting at Igab features a northwest-trending structural corridor hosted predominantly within a meta-sedimentary package running along the northern edge of a large duricrust plateau. The Koela targets appear to be steeply dipping to the west, with potential strike continuity linking multiple anomalies. However, colluvial cover derived from the plateau complicates surface interpretation in some areas, making drill testing essential to understand the full extent and continuity of mineralisation.

Tosso Creek: Evaluating Bulk Tonnage Potential

The Tosso Creek project in southern Suriname represents a different style of mineralisation, with trenching results indicating broad zones of lower-grade material - including 86 meters at 0.6 g/t gold - suggestive of bulk tonnage potential. The project is more remote than Greenheart's other Suriname assets, requiring it to support a standalone operation rather than benefiting from synergies with nearby mines. This geographic reality sets a higher threshold for economic viability.

Greenheart is conducting additional trenching with a second excavator to better define targets before committing to drilling in Q2 2026. The project features multiple geological settings, including north-south striking volcanic-sedimentary packages in the western portion and a northeast-trending granite contact in the south. Initial results come from the sedimentary-hosted western area, but the company is evaluating whether different host rocks might provide superior geochemical conditions for gold precipitation.

"We're seeing what we want to see, which is broad zones of mineralisation," Justin stated, adding that the team is still determining optimal drilling locations among the various target areas. The presence of mineralisation along granite contacts is particularly encouraging given the strain accommodation and structural complexity these features typically generate.

Technical Workflow Integrates Multiple Exploration Methods

Greenheart's exploration workflow integrates multiple techniques to build comprehensive geological models before drilling. Soil geochemistry and aeromagnetic surveys identify targets, followed by trenching and road cuts to create exposures into saprolite and saprock, providing direct observations of structural controls and mineralisation styles. In the deeply weathered tropical environment of the Guiana Shield, surface conditions create interpretation challenges, with Justin describing exposures as "basically a different shade of red muddy rock."

The choice between RC and diamond drilling depends on exploration objectives and mineralisation style. RC drilling offers speed and cost efficiency for testing large areas and defining near-surface oxide potential, but it provides limited structural information and requires dry hole conditions to avoid sample contamination. Drilling is kept above 100 meters depth to maintain sample quality, as wet samples below this threshold introduce contamination issues that compromise assay reliability. Diamond drilling delivers intact core for structural interpretation and is prioritised when understanding controls on high-grade mineralisation is critical.

Proven Management Focuses on Large-Scale Discovery

Greenheart's management team brings direct experience from Reunion Gold, where they made the Oko discovery in Guyana that ultimately attracted a takeover. This track record underpins investor confidence in the team's ability to recognise, acquire, and advance prospective ground in the Guiana Shield. The company's value creation strategy focuses on making large-scale discoveries and building resources rather than pursuing near-term production from oxide material, which Justin views as best utilised for early-stage revenue in larger mining operations.

"We're explorers, that's what we think we're good at," Justin emphasised, explaining that the company's priority is finding resources and defining their potential before determining optimal development paths. The team maintains discipline around capital allocation, ensuring funds are deployed into ground work rather than overhead, and demonstrating willingness to drop projects that don't deliver results.

2026 Outlook and Expected Catalysts

Greenheart anticipates delivering continuous drill results throughout 2026 as programs advance across all three Suriname projects. The Majorodam RC program is already producing samples, Igab diamond drilling commences in April, and Tosso Creek drilling is planned for Q2 following completion of the current trenching campaign. This sequencing should generate regular newsflow while advancing each project toward resource definition.

The key deliverables investors should monitor are significant intercepts demonstrating both grade and volume - the fundamental metrics that establish mineable potential and support resource growth. 

"We want to demonstrate that we have the potential to put together meaningful intersects that demonstrate that there's mineable potential on the project.”

Macro Thematic Analysis

The elevated gold price environment, with gold trading above $4,600/oz, has reinvigorated exploration activity in underexplored yet geologically prospective regions like the Guiana Shield. This Archean greenstone terrane shares geological characteristics with major gold-producing shields globally but remains significantly less explored due to historical accessibility challenges and limited infrastructure. The convergence of premium gold prices, increased investor appetite for precious metals exposure, and improved exploration technology creates favorable conditions for discoveries in frontier terrains.

Greenheart Gold's focus on the Guiana Shield capitalises on this opportunity while benefiting from established infrastructure around existing operations like Newmont's Merian and Saramacca mines. The region's geological potential for tier-one discoveries - multi-million ounce systems - combined with political stability in Guyana and Suriname, positions well-capitalised explorers to generate significant value. As Justin noted, 

"We're working in a part of the world where you still have potential to make tier one discoveries and that's really what we're putting forward to our investors." 

The challenge lies in securing quality ground as competition intensifies, making Greenheart's established presence and operational knowledge critical differentiators.

TL;DR

Greenheart Gold is advancing three exploration projects in Suriname with multiple drilling programs underway or starting in Q2 2026. High-grade trenching results at Igab (12m @ 4.82 g/t, 11m @ 9 g/t) will be tested with diamond drilling starting April, while a 10,000-meter RC program at Majorodam is testing a 15-kilometer gold anomaly. The experienced management team from Reunion Gold's Oko discovery is applying proven methodology to build multi-million ounce systems in the underexplored Guiana Shield.
