Current gold zones and mineral resource estimates at Marudi

The Toucan Ridge area is located approximately one kilometre east of the Marudi North zone and one kilometre north of the Mazoa Hill zone. The Mazoa Hill zone contains the project's current mineral resource estimate. Data analyzed suggest that the mineralized zone is open at depth and to the southeast.

Mazoa Hill zone mineral resource estimates:

• 259,100 indicated gold ounces within 4,428,000 tonnes grading 1.80 grams per tonne;
• 86,200 inferred gold ounces within 1,653,000 tonnes grading 1.60 g/t.

About the Marudi Gold project

The company is developing the Marudi gold project located in Guyana, South America. The project has an 18-year mining licence in good standing, all-season road access, infrastructure in place, with an established camp serviced by employees, service buildings and a full-time camp manager. The property has three known gold-bearing areas: the alluvial areas, the saprolite and the underlying hard rock.

There have been 42,000 metres of historical diamond drilling (141 holes) completed on the project by prior operators that have delineated two zones of mineralization -- the Mazoa Hill and Marudi North zones. The company has recently completed a mineral resource estimate on the Mazoa Hill zone containing 259,100 indicated gold ounces within 4,428,000 tonnes grading 1.8 grams per tonne gold and 86,200 inferred gold ounces within 1,653,000 tonnes grading 1.6 grams per tonne gold. The company has recently discovered a third mineralized zone -- Toucan Ridge. This zone is the current focus of the company's 2018 trenching program.

There exists excellent exploration upside for the further discovery of mineralized zones through the development of previously and newly identified mineralized bedrock targets on the project.

For information concerning the mineral resource estimate and the project, readers are encouraged to review "Technical Report: Marudi Property Mazoa Hill Mineral Resource Estimate," a technical report prepared for the company by Global Mineral Resource Services, and is available on the company website and under the company's profile on SEDAR.
