Guyana Goldfields Reports Revised Aurora Resource Statement; 27% Increase in Open Pit Gold Ounces in the Measured & Indicated Category
TORONTO, June 25, 2012 /CNW/ – Guyana Goldfields Inc. (TSX: GUY) (“GGI” or “the Company”) is pleased to report an updated mineral resource statement for its
100%-owned Aurora Gold Project in Guyana, South America. This new
estimate includes all drilling data obtained up to the end of April 30,
2012. The estimate was prepared by SRK Consulting (Canada), Inc.
(“SRK”) of Toronto, Canada in accordance with National Instrument
43-101 (“NI 43-101″) and provides an update to the previous estimate
released on September 9, 2011. The Bankable Feasibility Study is
scheduled for completion at the end of the calendar fourth quarter of
this year and will be based on the measured and indicated categories of
this revised resource estimate.
-- 78% of all mineral resources are in the measured and indicated category (6.54 million gold ounces) and 22% are in the inferred category (1.82 million gold ounces) -- 27% increase in open pit measured & indicated mineral resources from 2.18 to 2.76 million gold ounces -- 15% increase in combined open pit and underground measured and indicated mineral resources from 5.71 to 6.54 million gold ounces -- 55% increase in open pit and underground inferred mineral resources from 1.17 to 1.82 million gold ounces
Dan Noone, Vice-President, Exploration states, “The overall 830,000
ounces increase in measured and indicated contained gold ounces,
particularly the 580,000 ounces within the open pit, has the potential
to significantly impact the economics of the Bankable Feasibility
Study. Furthermore, the 650,000 ounces added in the inferred category
has significantly increased the overall total resource of the Aurora
Project into the ranks of world-class gold mines.”
Mineral Resource Drilling Data
The updated mineral resource statement incorporates drilling data
-- All drilling completed from May 31, 2011 to April 30, 2012, incorporating an additional 171 drill holes and 56,337 metres since the previous resource estimate issued on September 9, 2011. -- The new mineral resource statement considers a total of 366,851 metres of drilling in 1,110 holes.

Open pit resources are reported at a cut-off grade of 0.40 gpt gold within conceptual pit shells, Underground mineral resources are reported at a cut-off grade of 1.8 gpt gold and include all blocks above cut-off outside the conceptual pit shells. ** 2012 cut-off grades are based on a gold price of US$1,300 per ounce of gold and metallurgical recoveries of 97% and 94.7% for saprolite and fresh material respectively. Open pit resources are reported at a cut-off grade of 0.30 and 0.40 gpt gold for saprolite and fresh respectively within conceptual pit shells, Underground mineral resources are reported at a cut-off grade of 1.80 gpt gold and include all blocks above cut-off outside the conceptual pit shells.
Exploration drilling will continue for the remainder of the year and is
designed to significantly increase the discovery potential of local and
regional mineralized trends.
