Guyana Goldfields Inc. Announces Initial Exploration Drill Results from its Wynamu and Iroma Prospects

TORONTO, Dec. 4, 2017 (Canada NewsWire via COMTEX) --

Guyana Goldfields Inc. (TSX: GUY) (the "Company") is pleased to provide an update on exploration activities at both its Wynamu and Iroma Prospects.


The Wynamu prospect is located 40km northeast of the Aurora Gold Mine. A ten-hole drill program to an approximate depth of 100m has commenced to test a significant gold anomaly and trench sampling with best results of 58m @ 1.21 g/t Au. Four drill holes were completed so far totaling 500m.

Drilling results indicate two major lithologies - undifferentiated mafic volcanics and diorite. Mineralization is hosted in weakly 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. Partial assay results were received from two out of the four holes drilled. Hole WYD-01 returned a best intercept of 5m @ 6.08 g/t Au (uncut) including 2.5m @ 11.73 g/t Au.


The Iroma prospect is located 10km northeast of the Aurora Gold Mine. Gold mineralization is associated with NNW trending shear zones along an 8.5km central zone of anomalous gold. Five coherent gold zones were delineated along this NW trending corridor. An eight-hole drill program totaling 1,600m to an approximate depth of 240m is ongoing to test potential bedrock mineralization associated with gold mineralization in saprolite as identified from shallow drilling completed in 2013 (best results of 9m @ 2.28 g/t Au including 3m @ 8.17 g/t Au). Six holes have been completed so far totaling 1,455m.

Drilling has intersected several broad zones of intense silica-ankerite-pyrite alteration in saprolite and bedrock. Mineralization is dominantly hosted in intermediate intrusives (quartz diorite) with minor quartz porphyries and felsic dikes. Pyrite mineralization reaches up to 10% by volume in the altered zone. In the last hole that was completed, hole IRD-006, several broad intervals of shear/deformation zones were intersected in saprolite and bedrock. The shear zone in the bedrock is highly pyritic occurring as aggregates and blebs along the foliation planes. Assay results from the completed drill holes are pending.

Patrick Sheridan, Executive Chairman stated, "We are highly encouraged with these early stage drilling results. These new assay results reinforce our belief that the potential exists to discover another significant gold discovery in the Cuyuni greenstone belt."

Analytical testing and reporting of assays was conducted by Bureau Veritas and MSAnalytics laboratories. Both laboratories are based in Georgetown, Guyana.
