Greenheart Gold: Visible & High Grade Gold with Multiple Fully Funded Drill Targets

• Greenheart Gold is actively exploring a portfolio of early-stage gold projects across Guyana and Suriname, leveraging the experienced Reunion Gold exploration team.
• The company follows a systematic, data-driven approach to rapidly assess targets, advancing only those with meaningful mineralization while dropping others.
• Early RC drilling revealed encouraging gold mineralization, including intercepts like 6m @ ~8-9 g/t Au and 30m @ 2 g/t Au, prompting further structural and geological work.
• Projects like Tamakay and Abuya show selective land retention based on geochemical results; all assay data flows through a third-party managed database to ensure QA/QC.
• With multiple targets advancing, Greenheart expects to mobilize rigs to Majorodam and Igab later in the summer, following further geological analysis during the wet season.

Greenheart Gold (TSXV: GHRT), a gold exploration company formed through a spin-out from Reunion Gold and G-Mine Adventures, is focused on early-stage discovery across the Guiana Shield. The region—encompassing Guyana and Suriname—is known for its prolific, yet underexplored gold potential. Led by President and CEO Justin van der Toorn, Greenheart combines systematic exploration practices with a willingness to drop non-performing targets—an approach rarely executed with such discipline in the junior gold sector.

"We're looking for a portfolio of up to six early-stage exploration projects and that's where we see the potential of the shield… discoveries to be made in this part of the world."

Greenheart’s operating philosophy emphasizes efficient capital deployment and risk management while targeting meaningful mineralization. 

Strategy: Early-Stage Focus and 'Drill-to-Kill' Approach

Greenheart Gold prioritizes early-stage assets with geological signals of gold mineralization. Projects typically begin with broad-scale geochemical surveys over land packages ranging from 50 to 100 square kilometers. These are followed by trenching, RC drilling, and—if justified—transition to resource-focused core drilling.

"Not all of them are going to succeed. But we’re hopeful that a few of them will."

The company is actively working on two projects in Guyana and three in Suriname, with flexibility to expand the portfolio. Exploration teams employ ridge-and-spur sampling, grid soil programs, and trenching to vector towards mineralized structures—often guided by the presence of artisanal mining activity in the region.

Majorodam: Encouraging Results from First-Pass Drilling

Majorodam, one of Greenheart's key Surinamese projects, has delivered promising results from an early RC drill program conducted ahead of the typical trenching phase. The project benefits from excellent access via a paved road, allowing cost-effective mobilization.

“Some people might say you drilled 20 holes and only a few hit. But for an early-stage project, this is quite a big success.”

Notable results include:

• Hole 3: 6 metres at approximately 8–9 g/t Au
• Hole 10: 30 metres at 2 g/t Au, starting from 90m depth

Due to thick duricrust and weathered overburden, trenching was impractical, prompting the company to move directly to RC drilling. The results across multiple fences revealed widespread gold mineralization, validating the initial geochemical anomalies.

Next steps at Majorodam include mechanical excavation (road cuts) to expose fresh geology for mapping and structural interpretation. Diamond drilling is expected later in the summer when weather conditions improve.

Igab: Target-Rich Environment with Expansion Potential

Igab, located ~30 km south of Newmont’s Merian mine, presents both geological promise and strategic proximity to potential future processing infrastructure. The project was acquired from local artisanal miners and now features widespread geochemical anomalies.

“We've ended up with results… anomalies everywhere. Now we're trying to figure out which one's the best.”

Two areas stand out:

• Lemon Tree and Desiberg Zones: Exposed mineralization in outcrop and old workings, with visible gold in quartz veins
• Micro Target: Located on a duricrust plateau, now covered with a grid sampling program to assess orientation and extent

While earlier trenching efforts were inconclusive due to overburden and complex weathering, upcoming fieldwork includes additional trenching, road cut exposure, and ultimately drill testing.

Tamakay & Abuya: Selective Ground Retention & Target Reassessment

In Guyana, Greenheart continues to assess multiple early-stage prospects, including Tamakay and Abuya. The Tamakay project originally included a large volcanic terrain, but this ground was dropped following underwhelming geochemical results.

“We're not married to projects for the sake of them being there. If we don’t see the results we want, we’ll move on.”

Tamakay's remaining central zone features historic artisanal mining and underground shafts, now under investigation for potential high-grade vein clustering.

Abuya is still in its trenching phase, with no results reported yet. However, it spans over 100 square kilometers, and fieldwork is ongoing to refine its potential.

Tosso Creek: Early Stages in a Structurally Favorable Corridor

Tosso Creek is located south of the Brokopondo Reservoir, along a corridor marked by north-south trending volcanics and sediments. The area features existing artisanal mining and adjacent granite contacts—common host settings for high-strain gold deposits.

“We like to see these high-strain zones at the edge of granite bodies.” 

Phase one soil sampling has revealed anomalies, and an airborne LIDAR survey is planned to improve regolith mapping, assist with access planning, and inform future drilling. The project startup was delayed to late May due to elections in Suriname, but weather permitting, the field team expects to begin work imminently.

Data Integrity and Portfolio Execution

Greenheart outsources its data management to ensure third-party QA/QC oversight. All assay results from labs flow directly into the company’s secure database system—bypassing internal teams to ensure integrity.

"The issue in exploration isn't managing the data—it’s having people to look at it. All our assays come straight from the lab to our database team.”

The company’s portfolio approach, combined with robust data handling, gives investors confidence that capital is being deployed with discipline, and that discoveries are being pursued with rigor.

The Investment Thesis for Greenheart Gold

• Proven Technical Team: Led by the former Reunion Gold team, Greenheart has deep experience in the Guiana Shield and a track record of discovery.
• Low-Cost Discovery Leverage: Projects like Majorodam show high-grade potential with modest early-stage exploration spending, creating attractive risk/reward exposure.
• Disciplined Capital Allocation: The company advances only those projects with clear geological promise, actively dropping underperforming ground.
• Infrastructure Advantage: Select projects (e.g., Majorodam, Igab) are accessible by road and near major operations like Newmont’s Merian mine—lowering future development barriers.
• Well-Financed Platform: Greenheart has capital to sustain ongoing multi-project exploration, reducing dilution risk in the near term.
• Clear Milestone Path: Anticipated news flow includes geological mapping updates, trenching results, and new drill programs in H2 2025.

Macro Thematic Analysis

The Guiana Shield remains one of the last truly underexplored greenstone terrains with demonstrated potential for world-class gold deposits. Both Guyana and Suriname host significant historic and active gold production—largely artisanal—with substantial geological upside.

Major miners like Newmont and Zijin Mining are active in the region, validating its prospectivity and offering potential exit opportunities for junior players.

“We're in a part of the world where… we can make discoveries of outcropping mineralization. We don't need to spend forever on a project trying to figure out if there's something there.”

The favorable combination of geology, low exploration cost, and regional mining infrastructure make the Guiana Shield an attractive jurisdiction for risk-tolerant investors seeking leverage to discovery. Greenheart’s focus on systematic target testing increases the odds of scalable discovery and value realization.
