Guyana Goldfields Discovers a New Mineralized Gold Zone at the Aurora Gold
Project
As of
The best drill holes include MKD-45W which returned a significant intercept of 27 m at 4.94 g/t Au including 14 m at 8.60 g/t Au, MKD-52 which returned 17 m at 4.06 g/t Au including 6 m at 10.35 g/t Au, and BH09- RK-RMP-04 which returned 29 m at 4.60 g/t Au including 7.4 m at 14.19 g/t Au.

The new zone is located approximately 115 meters northeast from the east end of the main Mad Kiss zone. It resembles a tabular body with an east-west strike and has a dip of -60 degrees to the north. The new zone has a dimension of 40 meters along strike, 250 meters along dip and thickness of 20 meters. The zone is drill tested down to -260 m rl (relative level = sea level) (approximately 310 m depth from surface), and remains open at depth.
The new zone has been intersected in nine (9) holes. As well, four (4) holes drilled to the east of the new zone returned narrow Quartz-Feldspar Porphyry ("QFP") zones possibly cut by younger diorite intrusive.
The gold mineralization is associated with quartz-carbonate-sulfide veining and stockworks cross-cutting the QFP body. The high grade zone is characterized by 5-20% quartz-carbonate veining with 3-5% pyrite dissemination. The high grade shoot is from -150m rl to -260m rl and remains open at depth. This style of mineralization is similar to the main Mad Kiss gold mineralization. The QFP body appears to connect to the main Mad Kiss zone. There is a blind zone at line 9850N between 10320E and 10400E from -164 to -207 m rl that separates the two zones. The new zone is a viable target for underground mining and if the high-grade shoot expands farther to the west, this may extend the current Mad Kiss pit depth by 115 meters.
The mineralized zones were drilled in NQ core, sampled with an average length of 2 meters and assayed for Au using FA-AAS with Fire Assay- gravimetric finish for samples with (greater than)3000 ppb Au. Assays were done at Acme Analytical Laboratories in
This discovery is part of the ongoing infill and exploration drilling effort in the
