The data, information, and opinions contained or referred (the “Information”) in 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 “expected”, “targeted”, “advanced”, “appears”, “scheduled”, “guidance”, “on plan”, “test”, “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 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 in this document also include statements regarding: the Company’s strategy, projects, priorities and plans (including the Company’s proposed life of mine optimization plan at the Aurora Gold Mine), future financial or operating performance, business prospects, planned capital expenditures, cost reduction initiatives, exploration programs, plans and targets, corporate social responsibility initiatives, potential upgrades of mineral resources to mineral reserves, and certain corporate objectives, goals and plans for 2019. 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. Important factors that could cause actual results to differ materially or otherwise 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
regulators. Certain forward-looking statements contained herein may also be considered to be future-oriented financial Information or a financial outlook for the purposes of applicable Canadian securities laws. Future
conditions and proposed courses of action, based on the applicable management team’s assessment of the relevant Information available to them at the applicable time, and to become available in the future. In particular, the Information contains projected operational Information for future periods which are based on a number of material assumptions and factors. The actual results of the applicable operations for any period could vary from the amounts set forth in these projections, and such variations may be material. Further, there is no assurance or guarantee with respect to the prices at which any securities of the Company will trade, and such securities may not trade at prices that may be implied herein. See above for a discussion of the risks that could cause actual results to vary from such forward-looking statements. These forward-looking 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 Company 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), 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
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, sociopolitical, and marketing issues. For further information on the Aurora Gold Mine, see the Technical Report entitled, “Technical Report on the Aurora Gold Mine, Guyana” on the Company’s profile on SEDAR (the “RPA Report”). The compilation of the RPA Report, including the updated reserve and resource model and life of mine plan was completed by Jason Cox, P.Eng., David Ross, P.Geo.,and Katharine Masun,P.Geo., of RPA, who are independent Qualified Persons as identified by National Instrument 43-101 and have reviewed, approved and verified the technical content of this presentation. Unless stated otherwise herein, all scientific and technical data contained in this presentation has been reviewed, approved and verified by Mr. Ron Stewart (P.Geo) who is a qualified person for the purposes of NI 43-101 and is a member of the Association of Professional Geoscientists of Ontario.

Data Verification In October 2018, the Company implemented the Fusion Suite integrated data management system to accommodate data storage and management of geological, geotechnical, geophysical, geochemical, downhole survey, mapping, QA/QC, and sample data at the Aurora Gold Mine. In February 2019, the Company audited 7.5% of the master diamond drill hole database completed on its Mining Licence from 2004 to year end 2018. The audit included checking drill holes for errors in collar location, survey, and assay data. The latter involved comparing 11,104 digital assay records from the master database to 176 digital laboratory certificates. The Company did not identify any material limitations in verifying the data.

Notes: 1. CIM (2014) definitions were followed for Mineral Resources. Mineral Resources are inclusive of Mineral Reserves 2. Open pit Mineral Resources are reported at a cut-off grade of 0.52 g/t Au for saprolite and 0.70 g/t Au for fresh rock, and underground Mineral Resources are reported at a cut-off grade of 1.2 g/t Au for Rory’s Knoll area, and 1.7 g/t Au for other areas. Cut-off grades are based on a price of US$1,500 per ounce of gold and gold recoveries dependent on mine method, material type, and/or location. 3. Minimum mining widths of 5 m for open pit and 3 m for underground were used. 4. Bulk density is 2.8 t/m3 for fresh mineralization and 1.73 t/m3 for saprolite mineralization. 5. Stockpile data based on EOY 2018. 6. Mineral Resources are inclusive of Mineral Reserves. 7. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. 8. Numbers may not add due to rounding. 9. The mineral resource estimate was prepared by David Ross, P.Geo., and Katharine Masun, P.Geo., both of RPA Inc., “qualified persons” under NI 43-101 and independent of the Company. 10. The Company confirms that there are no known legal, political, environmental, or other risk factors that could materially affect the development of the Mineral Resources
