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 suggests 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 g/t; and,

  - 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 18-year mining license 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 has been 42,000 metres of historic diamond drilling (141 holes) completed on the project by prior operators that have delineated two zones of mineralization: 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 g/t and 86,200 inferred gold ounces within 1,653,000 tonnes grading 1.6 g/t. 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.

About Guyana

The Republic of Guyana is located in South America adjacent to Suriname. The country is English speaking and under British Common Law with a democratically-elected government. It has an established mining act and a rich history of gold production. In 2016, 690,000 ounces of gold was produced by operators mining in the country. The Fraser Institute's 2016 Annual Survey of Mining listed Guyana as the third best mining jurisdiction with regards to investment attractiveness in the Latin America and Caribbean Basin sub-group. The Guiana Shield is the geographic gold-hosting region, and is world-recognized as a premier gold region that is highly prospective, under-explored and has geological continuity with West Africa.* In 2016, two mines in Guyana declared the commencement of commercial production: the Aurora deposit (Guyana Goldfields) and the Karouni deposit (Troy Resources).
