Gold Hill Project

​

The Gold Hill Project is located in northwestern Guyana, approximately 13.5 km east of Aris Mining Corporation’s Toroparu project. Gold Hill is accessible by road using the Peruni laterite road to Toroparu then by ATV to the campsite, via the Mazaruni river to Poppy landing then by ATV, or by air from Georgetown to the Toroparu airstrip then via ATV.

​

Regionally, the project is situated in a northwest trending volcano sedimentary belt bounded to the northeast and southwest by granite-gneiss complexes. The property is underlain by volcanic, volcaniclastic and sedimentary units. There is a strong NW-SE structural fabric throughout, and up to three folding events. The main structural fabric hosts NW-SE shear veins and associated north-south and east-west extensional veins.

​

Numerous areas of significant artisanal saprolite mining activity have been observed on the property, which appear to be associated with quartz veining ranging from 15 cm to 40 cm wide and the property scale are aligned with the structural fabrics and shear veins observed on site. In areas of artisanal mining activity these veins appear to be widely distributed within the volcaniclastic rock units and evidence of sericite, carbonate and kaolin alteration assemblages have been observed. In addition to the granite intrusions to the east, there is also a dolerite intrusion located in the northeastern area of the property. This dolerite appears to be closely associated with areas of artisanal saprolite mining near the margins of the intrusion.

​

Structurally, the project area appears to have been deformed by multiple deformation events including D1 isoclinal folding, D2 folding and shearing, and D3 folding. The dolerite in the northwest may have provided a strong rheologic contrast, or buttress, around which folds and shears opened creating space for mineralizing fluids. Two northwest southeast trending shear zones have been identified transecting the project area, one to the northeast and one to the southwest. The shearing and deformation events create the potential for the development fluid pathways and traps for mineralization. The presence of multiple gold bearing vein systems being mined on the property suggests the presence of a hydrothermal system in the area that is likely associated with the observed alteration.

The Company has commenced geological mapping and has conducted an initial soil sampling program on a 400 m by 50 m sampling spacing. A drone magnetometry survey has also recently been completed over the eastern portion of the project area where the majority of artisanal mining is taking place. Results on the initial sol sampling program are pending.  For additional information on Gold Hill, including Greenheart Gold’s more recent exploration programs and results, please refer to our press releases, which can be found on our website.
