GUYANA GOLDSTRIKE COMPLETES MAPPING AND SAMPLING OF TRENCH TTR-18-12 AT TOUCAN RIDGE AREA, MARUDI GOLD PROJECT, GUYANA

Guyana Goldstrike Inc.'s technical team has completed sampling and mapping of trench TTR-18-12 at the Toucan Ridge area on its Marudi gold project located in the Guiana gold belt, Guyana, South America.

Trench TTR-18-12, which is located 500 metres northeast of trench TTR-18-06 along Toucan Ridge, was trenched a total length of 136.50 metres with 57 samples taken. It was trenched parallel to TTR-18-11 and was oriented to cross an outcrop of quartzite-metachert (host rock). The technical team successfully encountered and sampled intervals of hard rock and slightly weathered quartzite-metachert.

All samples have been sent to Actlabs for assay and results will be released once received and reviewed by the Company. The technical team continues to trench along Toucan Ridge moving in an eastward direction.

Current trenching at Toucan Ridge -- 1.75-kilometre area of interest

A total of 1,885 metres of trenching have been completed and 575 samples taken at the Toucan Ridge area. The area of interest continues for more than 1.75 kilometres to the east of trench TTR-18-06. To date, a total of eight trenches have been completed within the area of interest. Trench sites are planned where quartzite-metachert is exposed or interpreted to occur beneath the transported overburden.

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 quartzite-metachert (host rock) at Marudi

At Marudi, all important gold mineralization discovered to date is associated with the medial quartzite-metachert (host rock) unit of the Marudi Mountain formation. Gold occurs within the magnetite-hematite-rich quartzite and in the magnetite-silicate iron formation. Mineralization of the host rock may be affected at surface by the erosion at different levels of the strata. Therefore, all discoveries of quartzite-metachert on the property are considered important for the potential of containing mineralization at surface and/or at depth and should be explored through trenching and drilling.

Marudi geology

Gold mineralization at Marudi is regarded as being related to iron-formation-hosted gold (IFG) deposits that occur in other cratonic greenstone belts around the world. These deposits can be remarkably long-lived with sizable gold production. They have a strong association between gold and iron sulphide minerals, the presence of gold-bearing quartz veins and structures, the occurrence of deposits in structurally complex terranes, and the absence of lead and zinc enrichment.

Examples of some existing IFG deposits are: the Homestake mine, Lupin mine and Musselwhite mine.

The Homestake mine, located in South Dakota, United States, was the largest and deepest gold mine in North America. It has reported production of 43.9 million ounces of gold and was in production from 1878 to 2001 (source: Wikipedia).

The Lupin mine, located in Nunavut, Canada, no longer in production, produced approximately three million ounces of gold (source: Kinross website).

The Mussellwhite mine located in Ontario, Canada, has estimated reserves of 2.29 million ounces of gold and is owned and operated by Goldcorp and will be in production until 2020 (source: Wikipedia).

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.
