Assays High Grade Au Intersecting 7.21 g/t Au over 3.00 Metres within 18.90 Metres of 2.03 g/t Au in Trench TTR-18-08 at Toucan Ridge Area, Marudi Gold Project, Guyana  



Gold shear zones


Guyana Goldstrike Inc. (GYA.V) is pleased to reported assay results from Trench TTR-18-08 at the Toucan Ridge area on its Marudi Gold Project ("Marudi" or the "Property") located in the Guiana Gold Belt, Guyana, South America.

Trench TTR-18-08

Trenching successfully exposed the quartzite-metachert (host rock) in place with resulting assays returning values of 7.21 g/t Au over 3.00 metres within 18.90 metres of 2.03 g/t Au. The assay results are from samples taken in hard and slightly weathered rock of the quartzite-metachert.

These are the final assays from trench TTR-18-08. Additional assays are pending from trenches TTR-18-07, TTR-18-10 and TTR-18-11 and will be released once received and reviewed by the Company. The technical team continues to trench along Toucan Ridge, progressing in an eastward direction.

Please view below, "Table of Significant Gold Assay Results to Date" for all trenching results on the Property to date, and "Toucan Ridge Location Map" for the location of the Toucan Ridge area of interest and trenches.

Current Trenching at Toucan Ridge - 1.75 Kilometre Area of Interest


A total of 1748 metres of trenching has been completed and 518 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 7 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 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


Toucan Hill - Diamond Drill Hole TH 93-84


One historical hole has been drilled near Toucan Ridge. In 1993, Romanex-Sutton drilled 300 metres south of the ridge at the Toucan Hill area. The hole encountered a 39 metre section of elevated mineralization including 3 metres of 0.82 g/t Au at a depth of roughly 180 metres below surface. The hole terminated at a depth of 230 metres below surface in the quartzite-metachert host rock without drilling through it. The location of the hole is marked in the “Toucan Ridge Location Map” above.


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.
