This presentation

  • f

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

  • ur

actual results, performance

  • r

achievements,

  • r

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

  • n 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

  • f the Company's properties; uncertainties involved in the estimation of

resources and reserves; the possibility that required permits may not be

  • btained 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

  • ther 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

  • n

a number

  • f

assumptions, including assumptions regarding general market conditions, the availability of financing for proposed transactions and programs

  • n

reasonable terms, the cost

  • f

exploration and development and the ability of outside service providers to deliver services in a satisfactory and timely manner. Forward-looking statements are based

  • n

the beliefs, estimates and

  • pinions
  • f

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

  • f 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.

GRADE RECONCILIATION TO DATE

  • Grade reconciled very well in 2016 & 2017
  • Negative grade variance in 2018 explained by:
  • 2018 LOM plan assumed ore mined > ore processed of 0.2Mt in 2018, i.e. only medium & high grade

processed and low grade sent to stockpile

  • Slower mining rates YTD has resulted in ore mined < ore processed of 0.3Mt, resulting in processing
  • f low grade ore & low grade stockpiles ‐ delayed access to high grade ore originally expected in

4Q18

  • Expected average grade rebound to +3g/t Au in 4Q 2018 appears unlikely.

UNDERGROUND DEVELOPMENT

  • Development capex includes cost of

  • Development will provide access to Mad Kiss

  • Capital requirements are being reviewed by

management and contractor, with an expectation that a significant portion of 2019 capital will be smoothed out and deferred through 2020 without impacting the development schedule since capital was front‐ end loaded.

  • Ministry of Natural Resources develops, implements and oversees policies

for the responsible exploration, development and utilization of natural resources whilst ensuring the protection and conservation of the environment and advancement of the green economy.

  • Mining in Guyana is managed by the Geology and Mines Commission

(GGMC) under the Mining Act of 1989. The Act allows the GGMC to be the guardian of all minerals in Guyana. Therefore, permission must be received from the GGMC, before any exploration activity can begin.

  • The Guyana Gold Board was established on May 15, 1982 to manage the

business of trading gold in Guyana. The Board secures adequate supplies

  • f gold ensuring equitable distribution at fair prices and engages in other

commercial and industrial activities.

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. 4. Underground fresh rock reserves are reported at a cut-off grade of 1.5 g/t Au. 5. Mineral reserves are contained within mineral resources. 6. All figures have been rounded to reflect the relative accuracy of the estimates. Numbers may not add due to rounding 7.
