The Bonga Xploration team has visited the Property and has gained a full understanding of Guyana Goldstrike's expectations for the upcoming program.

The drilling program will consist of up to 2,500 metres and can be extended for additional metres. This program will test and confirm at depth the gold associated and correlated to anomalous gold mineralization reported in the sampling results from surface trenching and the magnetic anomalies identified along the length of the 1.75 km Toucan Ridge area.

Further details on the drilling and exploration program will be released once the company has finalized all logistics and contracts.

In 2018, a total of 12 trenches totaling 2,458 metres were completed at Toucan Ridge.

Over 850 trench samples were assayed from the Toucan Ridge area returning grades as high as 23.5 g/t gold.

About the Marudi Gold Project

The Company is developing the Marudi Gold Project, which has a 17-year mining license and is located in Guyana, South America. There has been 42,000 meters of historic diamond drilling completed on the project by prior operators that have delineated two zones of gold mineralization: Mazoa Hill and Marudi North zones. A mineral resource estimate has been completed on the Mazoa Hill Zone. It is open to mineralization in multiple directions and at depth.

The Company has also recently discovered a third mineralized zone, called Toucan Ridge, which is situated about 1000 metres to the northeast of the Mazoa Hill Zone. In addition to the known gold deposits and the new Toucan Ridge zone, the company has over 45 sq. kms of underexplored land and believes the greater land position has excellent upside potential for the discovery of new mineralized zones through the development of previously and newly identified mineralized bedrock targets on the project.

For information concerning the Mazoa Hill Zone Conceptual Pit Mineral Resource Estimate, 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 at: GYA Mazoa Hill Zone 43-101 and under the Company's profile on www.sedar.com.

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).
