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.

2017 Guidance: 2H/17 Higher Production & Lower Costs
• Lower end of the guidance range of 160,000 – 180,000 ounces of gold is
expected to be achieved.
• Due to mine sequencing, which envisions a significant increase in head grade
over the second half of the year, gold production is expected to be higher in
the second half of the year relative to the first half. In addition, stripping ratio is
expected to be materially lower in 2H/17.
• Due to the timing of sustaining capital expenditures, AISC¹ are expected to be
lower in the second half of the year relative to the first half.
2017 Guidance (@ $1,200/oz)
Gold production (ounces) 160,000 – 180,000
Cost of sales (production costs, royalty and
depreciation) ($ per ounce)
$800 - $850
Cash cost¹, excluding royalty ($ per ounce) $500 - $550

BROWNFIELDS EXPLORATION:
Ken Reading, Swamp Vein, & Iroma
Brownfields Exploration Targets
• Ken Reading Prospect
5-hole drill program has commenced.
• Swamp Vein
A small orientation magnetic survey was conducted
over Swamp Vein, with interpretation of results
pending. Mapping work of other brownfield targets
within close proximity to the Aurora mill to define drill
targets is currently ongoing.
• Iroma:
8-hole program totaling 1,600m has commenced.
Ken Reading Prospect

16. www.guygold.com 16
Iroma: Near Mine Open Pit Feed Target
• Located 10km NE of Aurora
• Gold mineralization is associated with NNW
trending shear zones along an 8.5km central zone
of anomalous gold.
• 8-hole drill program totaling 1,600m to an
approximate depth of 240m is ongoing to test in
bedrock significant results of saprolite drilling in
2013 (best results of 9m @ 2.28 g/t Au including 3m
@ 8.17 g/t Au). 6 holes have been completed so far
totaling 1,455m.
• Drilling has intersected several broad zones of
intense silica-ankerite-pyrite alteration in saprolite
and bedrock. Mineralization is dominantly hosted in
intermediate intrusives (quartz diorite) with minor
quartz porphyries and felsic dikes. Several broad
intervals of shear/deformation zones were
intersected in saprolite and bedrock in hole IRD-
006. The shear zone in the bedrock is highly pyritic
occurring as aggregates and blebs along the
foliation planes.
• Assay results from the completed drill holes are
pending.

17. www.guygold.com 17
GREENFIELDS EXPLORATION: Wynamu
• Located ~40 km NE of
Aurora.
• 6-hole, 1,200 meter drill
program underway.
• 4 drill holes were completed
so far totaling 500m with 2
assays received thus far:
• Hole WYD-01
returned a best
intercept of 5m @
6.08 g/t Au (uncut)
including 2.5m @
11.73 g/t Au.
• Drilling results indicate two
major lithologies –
undifferentiated mafic
volcanics and diorite.
Mineralization is hosted in
weakly to moderately altered
mafic volcanics. Alteration
consists of pervasive chlorite
and ankerite. Pyrite
mineralization is generally
weak and occurs as fine to
coarse grained
disseminations.
