Gold Exploration in the Guiana Shield
This profile is part of a paid investor education campaign.*
Guyana Goldstrike Inc. (TSXV:GYA,OTC:GYNAF,FWB:1ZT) is exploring and developing the advanced-stage Marudi gold project in Guyana, South America. Guyana Goldstrike holds an 18-year mining license for the property, which remains 85 percent unexplored. The property lies within the Guiana Shield which hosts numerous gold deposits and has geological continuity to West Africa. The Marudi project lies within the southern gold belt of the shield. The property is divided up into two developed zones and three exploration targets.
The two most developed areas of the property are Marudi North and Mazoa Hill. The Marudi North zone covers an 800-meter by 500-meter area, is open to the west and at depth and has the potential to host an 80,000-ounce deposit. Guyana Goldstrike intends to extend the mineralization at Marudi North. The Mazoa Hill zone, however, hosts a 2018 resource estimate that outlines an inferred resource of 86,200 ounces of gold grading 1.60 g/t gold and an indicated resource of 259,100 ounces of gold grading 1.80 g/t gold.
Guyana Goldstrike is focusing its efforts on the Toucan Ridge target. Over 2,000 meters of trenching has been completed to date at Toucan Ridge, and gold has been found in nine separate trenches. Mineralized interval lengths of up to 40 meters have been assayed and returned values up to 23.5 g/t gold. In 2019, Guyana Goldstrike uncovered the second discovery area to 2.3 kilometers northeast of Toucan Ridge. The new zone is geologically distinguishable from Toucan Ridge. Highlights from the company’s 2019 trenching program include 3.60 meters grading 4.28 g/t gold, 4.20 meters grading 3.8 g/t gold and six meters grading 1.46 g/t gold.
Guyana Goldstrike will continue with its exploration efforts to find additional zones of mineralization. The company expects to commence drilling at Marudi in the near term to deliver an updated resource estimate containing at least one million ounces of gold and to begin work on a preliminary economic assessment (PEA) within the next 24 months.
Guyana Goldstrike has received support from Zijin Mining Group (SHA:601899) who owns approximately 24.4 percent of the company’s shares. Zijin Mining has invested over $3 million in Guyana Goldstrike for exploration via its investment funds. Management and insiders are also notably invested in the company holding approximately 50 percent of the shares.

Mining in Guyana
Guyana has a long history of gold production and currently produces over 600,000 ounces of gold annually. All of the country’s gold production occurs within the Guiana Shield which has geological continuity with West Africa. The shield, however, is underexplored when compared to its African counterpart, providing exploration and development potential.
The democratic country has an established mining act and hosts a strong Canadian public mining company presence. Barrick Gold (TSX:ABX) has also expressed an interest in pursuing opportunities in the Guiana Shield by investing in early-stage exploration projects.
Marudi Gold Project
The 13,500-hectare Marudi gold project contains an 18-year mining license and is located 230 kilometers from Lethem in southern Guyana, South America. The property is accessible year-round by road and by air. The project also has an established mining camp already on-site.
The property is part of the Guiana Shield, a highly mineralized geological formation that covers over 415,000-square-kilometers. Mining in the Guiana Shield dates back to the sixteenth century, and numerous artisanal miners are still active across the region
Marudi North Zone
The Marudi North zone covers an 800-meter by 500-meter area and is open to the west and at depth. The target is one-kilometer north-northwest of the Mazoa Hill deposit and is 100 meters from the main camp. In 2012, a previous operator intersected 8.92 meters grading 2.95 g/t gold and 8.95 meters grading 0.26 g/t gold. The former operators also completed 3,327.40 meters of trenching and assay results returned values of up to 11 g/t gold.
The western extension of the Marudi North zone is open to the west and has the potential to host an 80,000-ounce deposit. In 2018, Guyana Goldstrike uncovered quartzite-metachert, the host rock for gold mineralization, in its first three trenches. The mineralization occurs between one and four meters below the surface. Assays from the trenches are pending.
Mazoa Hill Zone
The Mazoa Hill zone is a 300-meter by 300-meter zone that remains open to the southeast and at depth. A drilling program conducted in 2011 and 2012 intersected 6.5 meters grading 14.85 g/t gold, 33.6 meters grading 1.86 g/t gold and 37.5 meters grading 2.59 g/t gold. In 2019, the company identified previously unmapped outcrops along 1,100 meters of a magnetic trend at Mazoa Hill. Grab samples from four of the outcrops returned values up to 1.04 ppm gold. The trend extends north from Mazoa Hill for approximately 1,700 meters and remains underexplored.
Mazoa Hill 2018 Resource Estimate
In January 2018, Guyana Goldstrike released a resource estimate for Mazoa Hill. The report outlined an inferred resource of 86,200 ounces of gold grading 1.60 g/t gold and an indicated resource of 259,100 ounces of gold grading 1.80 g/t gold.
“The resource estimate for Mazoa Hill is a company milestone and a great step towards the further development of the Marudi gold project. The potential for additional ounces on the property is excellent when one considers the following factors: Mazoa Hill is open in a number of directions including at depth, the Marudi North zone is also open in a number of directions and contains a historic resource estimate and lastly, only five percent of the entire property has ever been explored,” said Guyana Goldstrike President and CEO Peter Berdusco.
Toucan Ridge target
The Toucan Ridge target continues in an easterly direction for over 1.75 kilometers. The eastern portion of the target is approximately 400 meters south of the Paunch target. In 2018, Guyana Goldstrike completed a mapping, sampling and trenching program at the Toucan Ridge target. Over 2,000 meters of trenching has been completed to date and resulted in the discovery of two new gold areas.
Gold has been found in nine separate trenches, and visible gold has been found in samples. Mineralized interval lengths of up to 40 meters have been assayed and returned values up to 23.5 g/t gold.
In 2019, Guyana Goldstrike uncovered the second discovery area to 2.3 kilometers northeast of Toucan Ridge. The new zone is geologically distinguishable from Toucan Ridge. Highlights from the company’s 2019 trenching program include 3.60 meters grading 4.28 g/t gold, 4.20 meters grading 3.8 g/t gold and six meters grading 1.46 g/t gold.
A total of 166.4 meters of surface trenching was completed at the Paunch target in 2018. The trenching program returned two meters grading 7.45 g/t gold, two meters grading 1.86 g/t gold and two meters grading 5.98 g/t gold in three separate trenches.
Guyana Goldstrike will continue with its trenching, sampling and geophysics to find additional zones of mineralization. The company also intends to commence drilling at defined target areas in the near term. Guyana Goldstrike expects to deliver an updated resource estimate containing at least one million ounces of gold and plans to begin work on a PEA within the next 24 months.
