About Greenheart Gold Inc.

Greenheart Gold is an exploration company that builds on a proven legacy of discoveries within the Guiana Shield, a highly prospective geological terrain that hosts numerous gold deposits yet remains relatively underexplored. The company is led by former executives and members of the exploration group of Reunion Gold, a team that was most recently noted for the discovery and delineation of the multimillion-ounce Oko West deposit in Guyana. Greenheart Gold is building on its management's technical knowledge, strong contact base, and previous success from exploring in the Guiana Shield to assemble, maintain and explore a portfolio of early stage exploration projects in Guyana and Suriname that are prospective for orogenic gold deposits.
