Forward‐Looking Statement
TSX : GUY
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 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 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
- verrun 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", “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.

Open Pit Mining Production Schedule
TSX : GUY www.guygold.com 6
- All mining to date has been focused in the Rory’s Knoll pit and will continue through the end
- f 2016.
- Gold production is staged with an initial open pit mill throughput rate of 5,000 tpd from the
Rory’s Knoll deposit expanding to 8,000 tpd in early 2017 with the inclusion of other open pit feeds from the Aleck Hill and Mad Kiss deposits.
Mill Expansion
TSX : GUY www.guygold.com 7
- During the initial years when saprolite and fresh rock ore are combined, mill throughput rate
ranges from 5,000 - 8,000 tpd. After eight years of operation, open pit mining will be completed.
- The 2016 capital cost for the mill expansion from 5,000 tpd to 8,000 tpd is approximately
US$5.6M and is funded from free cash flow and is contingent upon economic conditions. Major components of the plant were built for a 10,000 tpd throughput rate allowing for lower expansion capital.
- Requirements: 1 leach tank, 1 CIL tank, upgrade cyclones and pump, new screens (trash,
carbon, inter-tank, additional electrowinning cell, additional tailings pipeline and pump).
Project Facilities at End of Open Pit Mining

Underground Mining Production Schedule
TSX : GUY www.guygold.com 9
- Following a two year pre-production period, U/G mining at Rory’s Knoll commences in year
2022 as O/P mining operations are completed and sustains at 5,200 tpd for nine years.
- The U/G mine plan, mining method, production rate, and cost estimates were validated by
two independent FEED proposals completed in 2015.
- Rory’s Knoll orebody geometry and the results of geotechnical investigation and stability
modeling confirmed that it is amendable to the top–down open benching and sublevel retreat mining methods accessed by a decline with diesel truck haulage.
- The mine design accesses Rory’s Knoll through a portal at the 75 mRL and exploits the
deposit from -170 mRL to a depth of -770 mRL, starting with open benching and transitioning to SLR at the -395 mRL.
- Contractor mining strategy
- 88% ore recovery and 21% dilution

Conventional Processing
- A total of 3,072,000 ounces of gold (2,865,726 recovered) will be mined and processed over
the LOM.
- The average gold head grade over the LOM is 2.94 g/t Au. The mill throughput strategy in
2015 to 2019 is based on saprolite/fresh rock blend.
- Gold recovery is nominally 97.0% for saprolite and 94.4% for fresh rock.
- Total of 32.5M tonnes of ore processed.
- Fresh Rock is crushed prior to the single stage SAG mill grinding section followed by
leaching, CIL, carbon desorption, and eluate electrowinning.
- All of the tailings will continue to be treated using an air/SO2 cyanide detoxification system
prior to tailings disposal. Tailings is pumped to an engineered tailing management area.
- Gold doré is produced in the on-site refinery and stored in a secure vault prior to
transportation off-site.
Project Capital Costs
Globally Competitive
- The majority of the initial capital costs for Aurora Gold Project has been spent prior to
this feasibility study update.
- Currently estimated project capital cost include expenditures associated with processing
plant expansion to handle higher throughput rate, open pit sustaining capital, expenditures required to develop the underground, underground sustaining capital and closure costs.
