1. October 2012 Investor Presentation

2. Forward Looking Statement
This presentation of Guyana Goldfields Inc. (the "Company") contains statements that constitute "forward‐looking statements." Such forward‐looking statements
involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements, or developments in our industry, to
differ materially from the anticipated results, performance or achievements expressed or implied by such forward‐looking statements. Forward looking statements are
statements that are not historical facts and are generally, but not always, identified by the words "expects," "aims," "plans," "anticipates," "believes," "intends,"
"estimates," "projects," "potential" and similar expressions, or that events or conditions "will," "would," "may," "could" or "should" occur. Information inferred from
the interpretation of drilling results and information concerning mineral resource estimates may also be deemed to be forward looking statements, as such information
constitutes a prediction of what might be found to be present when and if a project is actually developed. Forward‐looking statements this document includes are
statements regarding: the Company's expectations regarding drilling and exploration activities on properties in which the Company has an interest; and the Company's
statements regarding estimates of resources on properties in which the Company has an interest. There can be no assurance that such statements will prove to be
accurate. Actual results and future events could differ materially from those anticipated in such statements, and readers are cautioned not to place undue reliance on
these forward‐looking statements that speak only as of their respective dates. Important factors that could cause actual results to differ materially from the Company's
expectations include among others, risks related to fluctuations in mineral prices; uncertainties related to raising sufficient financing to fund planned work in a timely
manner and on acceptable terms; changes in planned work resulting from weather, logistical, technical or other factors; the possibility that results of work will not fulfill
expectations and realize the perceived potential of the Company's properties; uncertainties involved in the estimation of resources; the possibility that required
permits may not be obtained on a timely manner or at all; the possibility that capital and operating costs may be higher than currently estimated and may preclude
commercial development or render operations uneconomic; the possibility that the estimated recovery rates may not be achieved; risk of accidents, equipment
breakdowns and labour disputes or other unanticipated difficulties or interruptions; the possibility of cost overrun or unanticipated expenses in the work program; the
risk of environmental contamination or damage resulting from the Company's operations; risks associated with title to mineral properties; and other risks and
uncertainties discussed appear elsewhere in the Company's documents filed from time to time with the Toronto Stock Exchange and Canadian securities regulators.
These statements are based on a number of assumptions, including assumptions regarding general market conditions, the availability of financing for proposed
transactions and programs on reasonable terms, and the ability of outside service providers to deliver services in a satisfactory and timely manner. Forward‐looking
statements are based on the beliefs, estimates and opinions of the Company's management on the date the statements are made. Except as expressly required by
applicable securities laws, the Corporation undertakes no obligation to update these forward‐looking statements in the event that management's beliefs, estimates or
opinions, or other factors, should change.
This presentation uses the terms "Inferred Resource", "Indicated Resource" and "Mineral Resource". The Company advises readers that although these terms are
recognized and required by Canadian securities regulations (under National Instrument 43‐101 "Standards of Disclosure for Mineral Projects"), the US Securities and
Exchange Commission does not recognize these terms. Readers are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be
converted into reserves. In addition, "Inferred Resources" have a great amount of uncertainty as to their existence, and economic and legal feasibility. It cannot be
assumed that any part of an Indicated or Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral
Resources may not form the basis of feasibility or pre‐feasibility studies, or economic studies except for a Preliminary Assessment as defined and permitted under
National Instrument 43‐101. Readers are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable. The Mineral
Resources stated in this news release are not mineral reserves and, in the absence of a current feasibility study, do not demonstrate economic viability. The
determination of mineral reserves can be affected by various factors including environmental, permitting, legal, title, taxation, socio‐political, and marketing issues.

9. Bankable Feasibility Study – Due Q4
Objectives:
 Lower initial
capital/operating costs Approx.
BFS depth
 3‐ phased production
approach
 Complete optimization of
mine and site plan
 Delivery of low capex/high
Wide open
grade, optimized mining laterally and
scenario at depth
www.guygold.com 9

10. Opportunities in BFS
Lowering Capex/Opex: Revisions to Plant/Mine Design
 Concentrate on mining deposit from surface to ~750m
 Elimination of Vertical Shaft (~$100M)
 Elimination of SAG Mill (~$50M)
 Elimination of Refrigeration Plant (~$15M)
 Paste Backfill Plant (~$20M)
 Power Usage Reduction (~$40M)
 Maximize throughput in first 10‐13 yrs of mine life
 Removal of some smaller pits considered to be marginal
 Reduction/optimization of mine footprint and overall haul distances
 Review/reduction of mobile fleet and equipment
 Review and tradeoff of two U/G mining methods :
 Mining Method #1 ‐ Blast Hole Open Stoping
 Mining Method #2 ‐ Sub‐Level Retreat
www.guygold.com 10

11. Staged Development Approach
Phase 1: Saprolite Mining
 Surface ‐ ~50m
 Mining and processing
oxidized ore for the first 2‐3
yrs of operations
 Scrubbing‐Leaching‐CIL‐EW‐
Refining
 Start‐up requires minimal
capital requirement through:
 Simplified processing plant
 Lower energy consumption
 No crushing/grinding
 Cash flow to help fund further
initial development costs
www.guygold.com 11

12. Staged Development Approach
Phase 2: Open Pit Hard Rock Mining
 Depth: Surface ‐ ~220m
 Crushing‐Grinding‐CIL‐EW‐
Refining
 For grinding, 3‐stage crushing
+ Ball mill required
 Recoveries ~90‐95%
www.guygold.com 12

13. Staged Development Approach
Phase 3: Underground Mining
Depth: ~220m – 750m: Analysis/tradeoff of 2 methods:
 1‐ Blast Hole Open Stoping
 2‐ Sub Level Retreat
Mining Method #1 – Blast Hole Open Stoping
 Depth: ~220m – 750m
 Access through decline
www.guygold.com 13

14. Staged Development Approach
Underground Mining Method #2 ‐ Sub‐Level Retreat
 Much lower operating cost ‐ no backfill
required
 Suitable for sub‐vertical pipe like ore
bodies (similar to Rory’s Knoll)
 Relatively simple “Top Down” method with
potentially high production rates
 Easy Access: Shallow to moderate depth
mining
 Successfully used on diamond mines in
South Africa and in Canada
 Operations partially funded through cash
flow

30. Site Geology
Geological Description
 Rory's Knoll mineralization: disseminated pyrite and gold mineralization associated with intense silica-
fuchsite-sericite-carbonate alteration in tonalite intrusive probably emplaced at the hinge of the folded volcanic
rock and metasediments.
 Mad Kiss mineralization: disseminated pyrite and gold mineralization associated with intense silica-fuchsite-
sericite-carbonate alteration in a quartz feldspar porphyry dyke.
 Aleck Hill mineralization: mesothermal gold veins hosted in the shear zones of metavolcanic and
metasedimentary rocks; occurs in a zone of pyrite-rich quartz-carbonate veins in volcanic rocks that are
enclosed in an alteration envelope which reportedly includes silica-sericite and calcite cement filling fractures.
