GUYANA GOLDSTRIKE COMMENCES TRENCHING, MAPPING AND SAMPLING AT THE MARUDI NORTH ZONE - WEST EXTENSION

Guyana Goldstrike Inc.'s geological team has commenced trenching, mapping and sampling at the Marudi North zone/West Extension area on its Marudi gold project located in the Guiana gold belt, Guyana, South America.

Peter Berdusco, president and chief executive officer, states: "This is the company's second area of geological interest out of nine targeted areas identified. The first area Paunch returned high-grade gold values indicating a downslope gold dispersion with gold trends that suggested an undiscovered bedrock source was in the vicinity. It is important to note that the Marudi North zone has been drilled and assayed by previous operators, therefore the West Extension is an excellent follow up exploration target to determine if there's continuity of gold present in the area. We eagerly anticipate further sampling and assay results from Marudi North/West Extension."

Marudi North zone/West Extension exploration

Locke Goldsmith, PEng, PGeo, vice-president of exploration, reports: "New trenching at Marudi North/West Extension has commenced. One trench has been completed to date, including sampling, mapping and photography. At this trench an outcrop of quartzite-metachert, the host bedrock, was identified and exposed at a depth of 2.5 metres. The Marudi North/West Extension has a very good potential for the discovery of gold."

Sampling and assaying

All samples collected during this program were delivered to Activation Laboratories Ltd. (Actlabs) located in Georgetown, Guyana, for gold content by fire assay (FA). Actlabs is ISO 17025 accredited and/or certified to 9001:2008. With over 25 years of experience, with full analytical laboratories that perform high-quality analysis to many industries around the world.

Historical trenching

Previous operators at Marudi reported 3,327.40 metres of trenching and assayed 1,069 samples with gold values assayed up to 11 grams per tonne of gold (source: D. Strickland, PGeo, National Instrument 43-101 technical report, Nov. 30, 2016).

Quality assurance/quality control

Actlabs is an ISO 9001:2008 qualified assayer that performs and makes available internal assaying controls. Certified blanks and standards are systematically used as part of Guyana Goldstrike's QA/QC program with one blank and standard inserted at every 20 sample intervals at Paunch.

Property 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 is located in South Dakota and 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.

The Lupin mine located in Nunavut, Canada, no longer in production, produced approximately three million ounces of gold.

The Mussellwhite mine has estimated reserves of 2.29 million ounces of gold and is owned and operated by Goldcorp and will be in production until 2020.

About the Marudi gold project

The company is developing the Marudi gold project located in Guyana, South America, the project is unique in that it has a 20-year mining licence in good standing, all-season road access, infrastructure in place, with an established mining camp serviced by employees, service buildings and a full-time mining manager. The property has three known gold-bearing areas, specifically 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. 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 and 86,200 inferred gold ounces within 1,653,000 tonnes grading 1.60 grams/tonne. There exists excellent exploration upside through the development of previously 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 at the company's website and under the company's profile on SEDAR.
