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 and mineral reserve
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
include 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 reserves and 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 and reserves; 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, the cost of
exploration and development 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",
“Measured 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 presentation 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.

Gold production 190,000-210,000
Cost of sales (production costs, royalty and depreciation) $850-900/oz
Cash cost¹, excluding royalty $430-480/oz
All-in sustaining1 (“AISC”) $830-880/oz
• Production is expected to be weighted towards the second half of the year due to mine
sequencing and increased throughput to be available with the completion of the phase 1
expansion.
• The 2018 mine plan is primarily made up of all hard rock ore from the central tonalite/diorite ore
at Rory’s Knoll and East Walcott deposits.
• Costs are based on an increased stripping rate during 2018, offset by the increased and more cost-
efficient production offered by the process plant expansion investments.

PRE-CRUSH TRIAL WORK
• Pre‐crush trial work commenced in November coinciding with Aurora becoming a
hard‐rock only operation
• Trial work to date has showed:
– The addition of the Pre‐Crush Circuit at a blend rate of approximately 15% yields a 10% increase
in throughput
– The throughput increase, at this rate, does not adversely affect the grind or recovery
• Processing with pre‐crush material show an average recovery of ~92.0% versus
an average recovery of 88.6% for the first nine months of 2017
• Pre‐crushing increases gold liberation making gold more suitable for gravity
recovery resulting in increased throughput & recoveries

19. www.guygold.com 19
BALL MILL & GRAVITY EXPANSION
• Addition of the ball mill will:
– Provide additional fine grinding
– Reduce the recirculating load on the SAG Mill
• Installation of the 2 x KC 20 gravity concentrators will:
– Reduce the recirculating gold load
– Further improve overall recovery via gravity concentration vs leaching/CIP
• ~8% reduction in Cyanide, SMBS and Copper Sulphate consumption
(annualized savings of US$ 0.5M) due to higher gravity recovery & reduced
gold loading in the leaching & CIP circuits
• 1,000 tpd ball mill & gravity concentrators are part of the Hope Bay mill
purchase made in 2016

Iroma: Near Mine Open Pit Feed Target
• Located 10km NE of Aurora
• First-ever drilling: Nine holes have been
completed to date totaling 2,000 meters of
drilling. Best results shown.
• Drilling will continue to test the mineralized
zones laterally and at depth. A drill rig road
is currently being pushed towards Areas 2
and 3 along the 8.5km gold anomalous
zone that will be drill tested.
• Gold mineralization is associated with
NNW trending shear zones along an 12km
central zone of anomalous gold.
• Prerequisites:
• Deep plumbing
• Brittle / Ductile Contrast
• Source of iron
• Sulphidation / Gold Event

Wynamu: First Ever Drilling Program
• Regional NE Structure
• First ever drilling: Four
drill holes have been
completed totaling 500
meters. Best results
shown
• Drill testing will
continue towards the
northeast of the drilled
area to test anomalous
gold in soils and
trenches.
• Anomalous Gold in soil
over 5 km
• Iron rich volcanic host
rock
• Pervasive iron
carbonate alteration

Greater Sulphur Rose Area & Arangoy
• Arangoy is located ~ 10 km NW of Sulphur
Rose
• Sulphur Rose Resource:
• M&I: 277,580 oz @ 1.04 g/t Au
Inf: 289,250 oz @ 1.42 g/t Au
• Soil sampling conducted within the vicinity
of the greenstone and intrusive lithological
contact indicated a large and coherent gold
anomaly in soils measuring roughly 1km by
0.5km.
• A trenching and drilling program is currently
being planned to test the gold anomaly.
Mobilization and resources to Arangoy
commenced in February 2018.
