Guyana Goldfields Announces New Gold Discovery at Aranka

TORONTO, Feb. 28, 2012 /CNW/ - Guyana Goldfields Inc. (TSX: GUY) ("GGI" or the Company") is pleased to announce initial trench and drill results from a new discovery at its Aranka group of properties. The Aranka group of properties is comprised of a contiguous 307,000 acre land package approximately thirty kilometres north east of the Company's flagship Aurora Gold Project.

At the Greater Sulphur Rose Area (GSRA), assay results have been received from initial trenching and drilling programs conducted at the "N1" prospect. The N-1 prospect is a 400m by 300m Au soil anomaly located approximately 5kms northeast of the Company's Sulphur Rose Resource (8,280,000 tonnes @1.04 g/t Au, total Indicated 277,580 oz Au and 6,330,000 tonnes @1.42 g/t Au, total Inferred 289,250 oz Au; See Press Release of Dec. 14, 2011). (see Figure 1: https://files.newswire.ca/826/Guyana_Figure_1.pdf).

Results from two (2) trenches out of six (6) excavated to date have returned a best interval of 1.41 g/t Au over 52 metres, including1.80 g/t over 32 metres and 4.34 g/t Au over 12 metres (Trench # 12-01A). The estimated true width is around 14.4 metres with an overall average grade of 2.65 g/t Au. Trenching has confirmed a 400 metre strike length consisting of altered and mineralized quartz diorite comparable to the style of mineralization at Sulphur Rose Gold deposit. Several other altered quartz diorite zones have been recognized and mapped in other trenches (see Figure 2: https://files.newswire.ca/826/Guyana_Figure_2.pdf).

Four (4) diamond drill holes, totalling 797 meters, have been drilled to date to test the sub-surface continuity of the Au anomalous zones delineated from the trenches. The Company has received assays from two holes to date, the rest are pending (see Figure 2: https://files.newswire.ca/826/Guyana_Figure_2.pdf).

Drill Hole N1D-01 returned gold grades of 1.06 g/t Au over 29 meters including a higher grade interval of 2.44 g/t Au over 8 metres and 14.13 g/t Au over 1 metre. N1D-02, drilled below N1D-01, yielded 4.35 g/t Au over 20 meters including higher grade intervals of 6.42 g/t Au over 13 metres and 53.21 g/t Au over 1 metre (Refer to table for complete results). Visible gold is observed in the cores of both drill holes. Results from N1D-01 and N1D-02 so far has confirmed an altered and gold mineralized quartz diorite host traceable to over 100 metres below surface; with a notable increase in gold grades at depth (see Figure 3: https://files.newswire.ca/826/Guyana_Figure_3.pdf).

Three (3) other gold targets aside from N1 have been identified adjacent to the Sulphur Rose artisanal mining area (refer to January 24 press release). Of particular interest is the S3 gold anomaly situated halfway between N1 and the Sulphur Rose Gold deposit was discovered in 2010 (see press release dated December 14, 2011). Results from infill soil auger sampling at S3 have delineated two gold anomalies measuring 400m by 300m and 300m by 200m, respectively; with the latest soil samples returning up to 8.40 g/t Au (see Figure 4: https://files.newswire.ca/826/Guyana_Figure_4.pdf). Trenching of this gold anomaly will commence next month.

Results of trenching and drilling at N1 and soil sampling at S3 support a potentially 10 kilometre long northeast trending corridor of gold mineralized zones similar to Sulphur Rose deposit and N1 prospect (see Figure 1: https://files.newswire.ca/826/Guyana_Figure_1.pdf). An extensive soil sampling program is ongoing to fully cover this northeast corridor.

Trenching and drilling will continue at N1 to trace the northwest and southeast extension of the mineralization. Two drill rigs are currently on site. The Company is mobilizing a third drill rig to the area in order to expedite the ongoing drilling program. Five geologists are actively exploring the Greater Sulphur Rose Area.

Dan Noone, VP Exploration stated, "The Company has identified multiple drill targets in the GSRA which we will drill aggressively in the coming months. The GSRA clearly hosts the potential for multiple zones of gold mineralization on a district-wide scale. We strongly believe additional anomalous zones remain to be found and significant resources are committed to regional sampling based on the recent discovery."

In addition, approximately 35-kms north from Sulphur Rose, a team of three geologists are on site to conduct in-fill soil sampling programs and follow-up stream sediment sampling at the Wynamu prospect. The Company previously identified a broad alteration zone measuring approximately 3km by 2km at this location. Currently, this program is helicopter-supported in order to fast track collection of data for drill target development.

The Company is currently utilizing the services of two independent laboratories, Loring Laboratories and Acme Analytical Laboratories Ltd both based in Georgetown, Guyana and Canadian operated facilities.
