Majorodam Project

​

The 251.5-square-kilometer Majorodam project in Suriname is located approximately 5 km south of the Saramacca deposit and approximately 2.5 hours’ drive from the capital city of Paramaribo[AK1.1], most of which is on paved roads. The project appears to exhibit favorable geology for the emplacement of gold mineralization, including reactive host rocks, regional and property scale deformation events including polyphase folding, and the presence of abundant artisanal workings within drainages downstream of the main target areas.
 
Majorodam is situated on the southern limb of the same volcanic trend and regional fold structure that hosts the Saramacca deposit which is owned and currently being mined by Zijin Mining (see Figure 1). The project also enjoys easy access and infrastructure, which is beneficial for cost-efficient exploration. Existing datasets include some preliminary geochemical sampling data, as well as an airborne magnetic and radiometric survey flown in 2019.

​

At Majorodam, by the end of 2025, Greenheart Gold had completed 2 phases of soil sampling and a significant amount of trenching as well as 3 drill programs, including a 2,138 m reverse circulation (“RC”) program and diamond drilling (“DD”) programs of 2,311 m and 1,055 m. From these exploration programs, Greenheart Gold has outlined a gold mineralized trend at Heuvel West and a second target called Heuvel East (see Figures 2, 3, 4). Gold mineralization at Heuvel West has been confirmed by a combination of DD, RC drilling and trench results over a length of approximately 1,000 m, including previously released highlight holes of 13.0 m grading 4.37 g/t Au, 15.3 m grading 3.72 g/t Au and 6.0 m grading 3.04 g/t Au. Soil anomalies as well as the geological and geophysical trends associated with Heuvel West indicate that the target structure appears to extend for approximately 15 km in length, including the recently discovered Gowtu target in the northwest corner of the project area. Only approximately 800 m of this target has been drill tested to date. The Heuvel East target, which lies approximately 0.5 km east of Heuvel West, has been intersected by 10 very closely spaced drill holes including 4 RC holes and 6 DD holes including 13.0 m grading 1.29 g/t Au and 40.0 m grading 1.49 g/t. Soil geochemistry, geophysics and geology associated with Heuvel East indicate that the structure could extend under cover for up to 3 km in length and remains open over most of this distance. 

​

In March 2026, the company has initiated a fourth drilling program consisting of approximately 10,000 m of RC drilling to further test the targets at Majorodam, including more detailed follow-up and step-out drilling at both the Heuvel West and Heuvel East targets and testing for additional areas of gold mineralization along the remaining 15 km target, including Gowtu.
