Guyana Goldfields Inc. reports significant mineralised intercepts from its first ever diamond drill programs at Iroma and Wynamu
Tuesday, Feb 06, 2018
Guyana Goldfields Inc. (TSX: GUY) (the "Company") is pleased to provide an update on its greenfield exploration activities including drill results from a combined 2,500 meters reconnaissance-style drill program at its Iroma and Wynamu prospects.


The Iroma prospect is located 10km northeast of the Aurora Gold Mine ("Aurora"). Gold mineralization is associated with north-northwest trending shear zones along an extensive 8.5km central zone of anomalous gold. Five coherent gold zones have been delineated along this northwest trending corridor. In 2017, a drill program initially focused on follow up work to test in bedrock significant results of saprolite drilling completed in 2013 (best results of 9 meters @ 2.28 g/t Au including 3 meters @ 8.17 g/t Au). Nine holes have been completed to date totaling 2,000 meters of drilling.

Assay results have been received for seven out of the nine holes drilled to date. Drill hole IRD-001 returned gold grades of 1.04 g/t Au over 14 meters with a higher-grade interval 1.90 g/t Au over 4 meters. Drill hole IRD-002, drilled 40 meters to the southeast of IRD-001, returned 1.01 g/t Au over 26 meters including higher grade intervals of 2.47 g/t Au over 7 meters and 3.69 g/t Au over 2 meters.

Drilling has intersected several broad zones of intensely altered silica-ankerite-pyrite. Gold mineralization is hosted in altered intermediate intrusives (quartz diorite) with minor quartz porphyries and felsic dikes. Several broad zones of pyritic shear zones were intersected both in drill testing and surface trenching. The shear zone is open laterally to the northwest and southeast of the current drilling area.

Drilling will continue to test the mineralized zones laterally and at depth. A drill rig road is currently being pushed towards Areas 2 and 3 along the 8.5km gold anomalous zone that will be drill tested.


The Wynamu prospect is located 40km northeast of Aurora. A shallow diamond drill program commenced in 2017 to test significant gold-in-soil anomalies and trench sampling with best results of 58 meters @ 1.21 g/t Au. Four drill holes have been completed totaling 500 meters.

Assay results have been received for all holes with drill hole WYD-01 returning gold grades of 2.67 g/t Au over 12 meters including higher grade intervals of 6.08 g/t Au over 5 meters and 11.73 g/t Au over 2.5 meters.

Drilling results indicate two major lithologies – undifferentiated mafic volcanics and diorite. Mineralization is associated with weak to moderately altered mafic volcanics. Alteration consists of pervasive chlorite and ankerite. Pyrite mineralization is generally weak and occurs as fine to coarse grained disseminations.

Drill testing will continue towards the northeast of the drilled area to test anomalous gold in soils and trenches.


The Arangoy prospect is located approximately 10 km to the northwest of the Sulphur Rose gold deposit which has a total gold resource of 566,830 ounces (277,580 ounces at 1.04 g/t Au in the measured & indicated category and 289,250 ounces at 1.42 g/t Au in the inferred category). Soil sampling conducted within the vicinity of the greenstone and intrusive lithological contact indicated a large and coherent gold anomaly in soils measuring roughly 1km by 0.5km. A trenching and drilling program is currently being planned to test the gold anomaly. Mobilization and resources to Arangoy will commence in the second half of February.

Dan Noone, VP Exploration, stated, "We are very encouraged with the preliminary results to date demonstrating multiple significant intercepts of gold mineralization with the first ever diamond drilling at both the Iroma and Wynamu targets. The drilling has outlined a favourable geological environment coinciding with deep seated structures and gold mineralization shown at surface. We are excited to further advance these targets as all the geological prerequisites are present for us to have confidence that we will encounter significant economic mineralization along this highly anomalous trend."

The Company is currently utilizing the services of two independent laboratories, Bureau Veritas and MSAnalytics. Both laboratories have facilities in Georgetown, Guyana. This news release and its contents have been reviewed by Mr. Augusto Flores IV (P.Geo), a qualified person within the meaning of National Instrument 43-101.
