Caut ution ionar ary y Stat tatement ment Regarding Forward Looking Information Certain statements included in this presentation constitute forward-looking statements, including those identified by the words “proposed”, “will”, anticipate”, “believe”, “plan”, “estimate”, “expect”, “intend”, “may”, “should” and similar words and expressions to the extent they relate to GT Gold Corp. (the “Company”) or its management. The forward-looking statements are not historical facts and are based on current expectations and various estimates, factors and assumptions, and therefore involve known and unknown risks, uncertainties and other factors. Any forward-looking statements represent the Company’s estimates only as of the date of this presentation and should not be relied upon as representing the Company’s estimates as of any subsequent date. The material factors and assumptions that were applied in making the forward looking statements in this presentation include: execution of the Company’s existing plans or exploration programs for its properties, which may change due to changes in the views of the Company, or if new information arises which • makes it prudent to change such plans or programs; and • the accuracy of current interpretations of geochemical, geophysical, drilling and other exploration results, since new information or new interpretations of existing information may result in changes in the Company’s expectations. Readers should not place undue reliance on the Company’s forward-looking statements, as the Company’s actual results, performance or achievements may differ materially from any future results, performance or achievements expressed or implied by such forward-looking statements if known or unknown risks, uncertainties or other factors affect the Company’s business, or if the Company’s estimates or assumptions prove inaccurate. Therefore, the Company cannot provide any assurance that such forward- looking statements will materialize. The Company disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. QA/QC PROCEDURES GT Gold has implemented a rigorous quality assurance / quality control (QA/QC) program to ensure best practices in sampling and analysis of RC chips and diamond drill core, the complete details of which can be viewed on the Company’s website at http://www.gtgoldcorp.ca/projects/tatogga/ For full details on both Saddle North and Saddle South reverse circulation and diamond drill program assay results widths reported in this presentation, please refer to the corresponding press release available on the Company website at www.gtgoldcorp.ca/news/. All assays are performed by ALS Canada Ltd. (Minerals), with sample preparation carried out at the ALS facility in Terrace, BC, and assays at the North Vancouver laboratory. Assay values are uncut. For gold, fire assays are performed as per ALS protocol Au-AA26 (0.01-100.00 g/t Au) using 50 grams of sample with assays equal to or greater than 5 g/t Au calculated gravimetrically, and lower-grade samples measured by (AA) atomic absorption. All samples that return equal to or greater than 5 g/t Au from initial fire assaying are additionally sent for screen metallic analysis using the remainder of the pulp (~950 grams of sample). This step is taken to ensure that any coarse grained, nugget gold fraction that may have been missed in the fire assays has been captured. GT Gold Corp. ’s Qualified Person as defined by National Instrument 43-101 is Michael Skead, FAusIMM, VP Project Development. Mr. Skead has reviewed and approved the technical information in this presentation. TSXV: GTT 4

Saddle North Geolog ologic ical al Mo Mode del
SADDLE NORTH GEOLOGICAL MODEL Preparation : Core Relog and Process Overview • Multi-element geochemistry used 41 Saddle North drill holes to define cryptic lithologic breaks (31,397 metres) relogged • for lithology, alteration & structures Geophysical modelling of magnetic over winter 2019/2020 and Induced Polarization data used to delineate various units of lithological, alteration types, and structures Geologists at work in logging facility TSXV: GTT 8
SADDLE NORTH GEOLOGICAL MODEL Preparation : Process Overview • A series of hand drawn cross sections and level plans were completed for lithology, structure, alteration and mineralization • Scanned and georeferenced sections were manipulated using Leapfrog software to create a well- constrained 3D geological model TSXV: GTT 9
SADDLE NORTH GEOLOGICAL MODEL Structure : Physical Bounds Two major structures bound mineralization at Saddle North 1. Poelzer Fault • Well-defined and very predictable • Strongly foliated zone forming the footwall to the known mineralized zone 2. Southern Fault • Relatively planar • Marks the southern contact of porphyritic intrusive rocks with host volcanic rocks • Characterized by more brittle fracturing TSXV: GTT 10
SADDLE NORTH GEOLOGICAL MODEL Lithology: Porphyry • Gold-rich copper porphyry centered on a series of monzodiorite and monzonite intrusions • Intrusive complex interpreted to represent a series of igneous bodies intruded over a relatively short period of time in late Triassic • Minor post-mineralization felsic and mafic dykes also observed • Host country rocks belong to the Triassic Stuhini Group • The intrusive complex and its host rocks (Stuhini Group) are overlain unconformably by the Lower Jurassic Hazelton Group . TSXV: GTT 11
SADDLE NORTH GEOLOGICAL MODEL Lithology : Mineral Phases • Eight lithology phases defined: two distinct inter- mineral phases (I1-I2) and six less distinct and generally better-mineralized older phases (P0-P5) Intermineral Phase 2 (“I2”) Intermineral Phase 1 (“I1”) • Cross section through lithologic model, showing porphyry phases, Stuhini Group host volcanic rocks, and overlying Hazelton Group clastic and subordinate volcanic rocks. TSXV: GTT 12
SADDLE NORTH GEOLOGICAL MODEL Mineralization : Lithology and Grade • Porphyry phases have significant controls on Au, less so on Cu P1 Au Cu P2 P3 P4 TSXV: GTT 13
SADDLE NORTH GEOLOGICAL MODEL Alteration : Potassic • Potassic alteration - the dominant style of alteration associated with intense quartz-sulphide A-style quartz vein stockworks that carry higher-grade Au and Cu at Saddle North Potassic: low Potassic: moderate Potassic: high Saddle North core showing potassic alteration TSXV: GTT 14
SADDLE NORTH GEOLOGICAL MODEL Alteration : Quartz-Sericite-Pyrite (QSP) • QSP alteration (phyllic alteration) – a moderate to intense hydrothermal alteration found both above & on the shoulders to the potassic core of the system with strong showing in the Poelzer footwall Poelzer Hangingwall Poelzer Hangingwall Poelzer Footwall TSXV: GTT 15
Weak SADDLE NORTH GEOLOGICAL MODEL Mineralization : Alteration and Grade • Potassic alteration (potassium feldspar, biotite and magnetite) strongly controls grade Au Cu Moderate Strong TSXV: GTT 16
3D View SADDLE NORTH GEOLOGICAL MODEL Mineralization : Copper Equivalent Grade Shells • Clear association of Cu and Au grades with potassic alteration (potassium feldspar, magnetite and biotite) and lithology phases Lithology Alteration 0.25 % CuEq 0.25 % CuEq 0.75 % CuEq • 0.75 % CuEq Sections and 3D view looking west- 1.5 % CuEq northwest to 1.5 % CuEq northwest: showing correlation between copper equivalent grade and alteration (left) and lithology (section at middle, 3D at top) TSXV: GTT 17
