This document provides an overview of Guyana Goldfields Inc., a gold mining company with operations in Guyana. It summarizes the company's recent financial and operating performance, including achieving production guidance in its first year of commercial production. It also outlines the company's plans for organic growth through a phased mill expansion to increase production to over 200,000 ounces annually by 2018. Additionally, it highlights the company's exploration potential through a large land package in an underexplored greenstone belt, with the goal of discovering a second mine.

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.

chargeability anomaly in saprolite and
bedrock.
• A regional soil sampling program along the
Sulphur Rose corridor is underway which will
cover an area of 36km² with a projected 3,400
samples to be collected.

GREENFIELDS EXPLORATION: Wynamu
• Road access
• Regional soil sampling program
commenced in Q4 2016 and is
still ongoing. Activity will consist
of a grid soil and infill deep soil
augers. The area covers
>12km² and is located west-
southwest of a known drill
target.
• 10 hole drill program is
proposed for Q2 2017 to test a
significant gold anomaly and
trench sampling with best
results of 58m @ 1.21 g/t Au.

1.Mineral Reserves are based on a gold price of
US$1,200 per ounce, 8% royalty and an
average metallurgical recovery of 96.0% for
saprolite and 94.0% for fresh rock material.
2.Open pit saprolite and rock reserves are
reported at a cut-off grade of 0.44 g/t Au and
0.42 g/t Au for vein and upper saprolite
material respectively. Open pit rock reserves
are reported at a cut-off grade of 0.76 g/t Au
and 0.64 g/t Au for vein and Rory’s Knoll rock
material respectively.
3.Underground fresh rock reserves are reported
at a cut-off grade of 1.5 g/t Au.
4.Mineral Reserves are contained within
Mineral Resources.
5.SRK is not aware of mining, metallurgical,
infrastructure, permitting, or other factors that
could materially affect the mineral reserve
estimates.
1. Mineral resources are inclusive of mineral
reserves. Mineral resources are not mineral
reserves and do not have demonstrated economic
viability. All figures have been rounded to reflect
the relative accuracy of the estimates.
2.Open pit mineral resources are reported at a
cut-off grade of 0.30 g/t for Saprolite and 0.40
g/t for Fresh rock respectively, and underground
mineral resources are reported at a cut-off grade
of 1.8 g/t. Cut-off grades are based on a price of
US$1,300 per ounce of gold and a gold
recoveries of 97 percent for saprolite and 94.5
percent for fresh material.
3.Mineral resources have been adjusted using the
2016 EOY topography, to account for open pit
mining to date, and include ore stockpile
inventories as of EOY 2016.

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.
