TORONTO, Dec. 21 /CNW/ - Guyana Goldfields Inc. (TSX: GUY) ("Guyana" or the "Company") is pleased to announce that ongoing drilling at the Company's 100%
owned Aurora Gold Project has intercepted significant widths and grades
of gold mineralization, extending the previously announced new
discoveries (see Press Releases dated April 20 and August 18, 2010) to
vertical depths of 420 meters at Aleck Hill and 500 meters at the Mad
Kiss area. The project is currently the subject of a definitive
feasibility study to be completed in Q4 2011 with a resource estimate
drill cut-off date of June 30, 2011. Prior to that, the Company is
preparing an updated resource estimate to be announced in mid-February
2011 which will include all known mineralization up to mid-November
2010.


Assay results from fifteen (15) new drill holes in the new Aleck Hill
zone are reported hereunder. Highlights include drill hole AHD-145
which returned 50m @ 3.9 g/t Au (3.02 g/t Au cut to 25 g/t Au) at a
vertical depth of 420 meters. Included within this broad intercept is
a high-grade zone of 16m @ 10.59 g/t Au (7.85 g/t Au cut to 25 g/t Au).
In addition, drill hole AHD-161 intercepted 62.44m @ 2.68 g/t Au
including the following high-grade intercepts:



6.08m @ 8.33 g/t Au


6.06m @ 5.11 g/t Au


6.20m @ 8.92 g/t Au



These results demonstrate the down-dip potential of the Aleck Hill
resource and suggest significant potential for high-grade gold
mineralization at depth. True widths of gold mineralization in the
Aleck Hill area vary from 25m to 50m and all gold zones remain open to
depth.


Drilling in the Mad Kiss zones (west, east and main) also continues to
expand previously announced new areas of gold mineralization. Nineteen
(19) new drill holes are announced hereunder. Highlights include:



MKD-99 - 16m @ 4.12 g/t Au (including 4m @ 10.95g/t Au)


MKD-107 - 18m @ 2.03 g/t Au (including 3m @ 11.60g/t Au) and - 8m @ 5.17
g/t Au


MKD-109 - 8m @ 7.13 g/t Au


MKD-111 - 13.95m @ 4.08 g/t Au



True widths of gold mineralization in the Mad Kiss zones vary from 10m
to 35m and all gold zones remain open to depth.


All of the latest results from the ongoing "Golden Square Mile" drilling
program are tabulated in the attached intercept spreadsheet. These
results will be included in an updated resource estimate for the Aurora
Gold Project, to be released in mid-February 2011.
