Details of Drill Results:
Irene-Goldstar Epithermal Corridor
Four drill holes, totalling 555.18 metres (Table 3), were drilled in the Mount Freegold area during 2020 exploration. Three of the four holes collared in previously undrilled portions of the Irene-Goldstar Epithermal Corridor, a 3.7 kilometre long zone of gold and silver rich epithermal and skarn mineralization associated with a major splay of the Big Creek Fault (first outlined in PR20-03).
Mineralization within the Corridor (Figure 1) was first identified near Mount Freegold in 1930 with erratic but significant gold-rich intercepts of the Skarn Zone (e.g. chip samples that returned up to 366 g/t Au and 106 g/t Ag over 5 metres) and the Goldstar Vein epithermal system. In 1989 C. A. Main estimated a mineral inventory for the Goldstar Vein at 123,000 tonnes of 4.21 g/t Au and 47.2 g/t Ag contained within a shallow pit approximately 250 metres long by 60 metres deep2. Prospecting 2.5 kilometres to the northwest of the Goldstar Vein led to the discovery of the Irene Vein in 2013, and inaugural drilling of the vein in 2018 outlined a mineralized strike length of at least 450 metres, with grades of up to 20.7 g/t Au over 0.70m (PR19-02). Limited prospecting and trenching between the Goldstar Vein and Irene Zone resulted in significant grab (e.g. 425 g/t Au and 321 g/t Ag) and chip sampling from trenches (e.g. 3.85 g/t Au and 103 g/t Ag over 2m) at the Red Fox/Vindicator Zone, strongly indicating continuity of this mineralized trend.
The 2020 drill program along the Irene-Goldstar Epithermal Corridor successfully tested the down-dip extent of the Goldstar Vein and demonstrated continuity of both skarn and epithermal vein styles of mineralization within the 2.5 km-long previously undrilled portion of the corridor.
Drill hole IGC20-03 tested beneath the known extent of the Goldstar vein and intersected 1.59 g/t Au, 96.04 g/t Ag, and 2.28% Cu over 1.56m at 152 metres depth extending the Goldstar Vein by at least 85 metres down dip (Figure 4). This intercept demonstrates continuity of the high-grade vein to depth, and presents an immediate opportunity for resource definition work along the Corridor.
Drill holes IGC20-01 and IGC20-02 form a fence across the Irene-Goldstar Epithermal Corridor at the Red Fox/Vindicator Zone and successfully extend gold, silver, and base metal mineralization within the corridor by at least 570 metres along strike from the nearest drill hole at the Goldstar Vein (Figure 2). IGC20-01 intersected massive magnetite at 33 metres depth, assaying 7.49 g/t Au and 37 g/t Ag over 1 metre, while testing a moderate magnetic response along the flanks of a prominent 870 metre magnetic not tested by drilling in this area (Figure 3).
Additional intersections of new epithermal gold and silver mineralization in all four 2020 drill holes support continuity of both gold-rich skarn and epithermal vein mineralization within the Corridor (e.g. values up to 2.87 g/t Au and 12.33 g/t Ag over 4.57m in IGC20-02). IGC20-04 also identified epithermal mineralization, returning 1.14 g/t Au and 10 g/t Ag over 1.02m, but terminated prematurely due to a catastrophic drill failure at the end of the program.
Of the 3.7 kilometre length of the corridor, less than 2 kilometres have currently been tested by drilling. Inaugural drill testing at the Red Fox/Vindicator Zone is strong evidence for continuity of mineralization through the entire corridor. Work in 2020 also included updating infrastructure in the area, which will allow for efficient access to untested portions of the corridor in 2021.

Jesse Halle, Vice President of Exploration for Triumph Gold commented “Multi-gram gold and silver results from the southeastern and central portions of the Irene-Goldstar Epithermal Corridor provide ample incentive to continue exploration and definition of this long and fertile mineralized system. Elsewhere in the corridor, increased drill density has been the key to identifying higher grade sections of the system – with recent compilation and 3D modelling we are now able to explore more effectively and efficiently than ever before.”
Revenue-Nucleus Area
Five drill holes totalling 1513.34 metres were completed in the Revenue-Nucleus area during 2020 exploration (Table 3). The Revenue-Nucleus Area is defined by a 6 kilometre long intense soil geochemical anomaly related to widespread porphyry copper-gold and associated epithermal mineralization. Since 2017, renewed focus on the area has resulted in multiple discoveries including the high-grade Blue Sky and WAu Breccias.
2020 exploration resulted in multiple mineralized drill intersections in the Revenue-Nucleus Area (Table 2) including highly anomalous gold related to newly discovered structures at the Keirsten Zone in KZ20-01, previously unidentified gold enrichment in an oxidized horizon from surface (within a broader interval of highly-anomalous gold and copper) at Keirsten South in KZ20-02, and multiple intersections of over 1 g/t gold at Revenue East in RVD20-02 and RVD20-03.

Keirsten Zone and Keirsten South
Two holes were drilled in the Keirsten area during the 2020 exploration season (Figure 5). KZ20-01 was designed to target strong coincident chargeability and magnetic geophysical anomalies in the Keirsten Zone, highlighted by a new Drillhole-Constrained 3D Magnetic Inversion Model. The drillhole intersected altered granodiorite and porphyritic dykes, with a structurally-controlled, weak to moderate oxide overprint persisting to 175 metres depth. Modelled magnetic geophysical anomalies were supported by observed magnetics in drill core resultant from anomalous concentrations of pyrrhotite and primary magnetite. Gold mineralization increased between the magnetic anomalies, within a faulted domain host to various porphyritic dykes, returning values up to 1.37 g/t Au over 1.27m (Table 2). This highly prospective, over 500 metre long structural-magmatic corridor stands out as a broad magnetic low (Figure 6) not previously tested by drilling, despite being coincident with significant Cu and Au in soil anomalies.
KZ20-02 was drilled a kilometre south of KZ20-01 and was designed to explore a 400 metre wide by 400 metre long gold and copper geochemical anomaly. The hole encountered a zone of iron oxidation returning gold grades of 2.2 g/t Au from 1.45 to 4.57 metres (Table 2), and elevated gold to 16.76 metres. Pervasive iron oxidation extends to approximately 40 metres downhole but persists to 110 metres as moderate to locally intense patches. Assays from this interval yielded 0.3 g/t AuEq3 over 87 metres from top of hole (Table 2). This drillhole intersected clay-altered monzonitic to monzodioritic rock with quartz veins and local feldspar porphyry dykes to approximately 230 metres depth where it penetrated Yukon Tanana country rock. Gold, copper and molybdenum were highly-anomalous throughout the hole indicating proximity to a porphyry-related mineralizing system.
Brian Bower, Lead Technical Director for Triumph Gold added “The intersection of highly-anomalous gold in this area makes Keirsten South an exciting new zone warranting more exploration. The technical team is reviewing spectral data to determine alteration zonation and is now modelling the oxidation surface to determine the oxide gold potential of the area.”
Revenue East
Revenue East is approximately 250 metres east of the high-grade gold and copper Blue Sky and WAu Breccias and is defined by an over 400 metre long gold, copper, and bismuth geochemical anomaly. Three drill holes were completed in the area during the 2020 exploration program, all confirming widespread gold mineralization in the area. Visible gold and bismuthinite were identified in drill core from RVD20-01 and RVD20-02 (Figure 5) and elevated gold grades of up to 1.64 g/t Au over 1 metre were intersected (Table 2). Results confirm that the geochemical anomaly is in-situ and is an effective vector to subsurface mineralization.
RVD20-03 (Figure 5) was designed to test another geophysical anomaly identified by the Drillhole-Constrained 3D Magnetic Inversion Model. Drilling confirmed a magnetic body immediately following a shear zone at approximately 275 metres depth (Figure 7). The drill hole contained visible gold and bismuthinite associated with quartz-carbonate veining, as well as long intervals of anomalous gold and copper, locally returning grades up to 1.51 g/t Au over 2 metres (Table 2). The anomalous magnetic target was encountered where expected providing additional support to the accuracy and predictability of the 3D magnetic inversion model.

Covid-19 Response
Triumph Gold is committed to the health and safety of its employees and contractors. With recommendations from the Yukon Government and Yukon Chamber of Mines, the Company developed and implemented infection prevention and control measures at the Freegold Mountain Project to help reduce and minimize the risk of potential COVID-19 transmission in the camp and related work sites. During the 2020 field campaign, employees, contractors, and visitors were regularly monitored for symptoms and required to adhere to federal and territorial regulations, as well as Company prevention policies outlined in the Triumph Gold Corp COVID-19 Operational and Emergency Response Plans. Visitors and cross-shifts were not permitted during the field program, and camp employees and service providers were sourced from Yukon, with the exception of Triumph Gold corporate management who strictly followed regulations and guidelines upon entering the Territory).
Sampling Methods and Qualified Person
Drill core samples ranged between 0.5 and 2 metres length and were cut at Triumph Gold’s core logging facility at the Freegold Mountain Project. The samples were analyzed by SGS Canada of Vancouver, British Columbia. They were prepared for analysis according to SGS method PRP89: each sample was crushed to 75% passing 2mm and a 250g split was pulverized to better than 85% passing 75 micron mesh. Gold was tested by fire assay with atomic absorption finish on a 30g nominal sample (method GE_FAA30V5), and samples that tested over 10 g/t Au were retested using a 50g sample and a gravimetric technique. Additional 33 elements were tested by ICP-AES using a four-acid digestion (method GE_ICP40Q12), over-limit samples for copper were retested using the same technique, but with ore grade four acid digestion and a higher range of detection (method GO_ICP42Q100). Quality assurance and control (QAQC) is maintained at the lab through rigorous use of internal standards, blanks and duplicates. An additional QAQC program was administered by Triumph Gold: A minimum of three quality control samples, consisting of blanks, certified reference standards and duplicates, are blindly inserted into each 75 sample batch. QAQC samples that return unacceptable values trigger investigations into the results and reanalysis of samples that were tested in the batch with the failed QAQC sample.

Notes
1 Reported assays are uncut length-weighted averages and represent drilled core lengths. The true width of reported mineralization is unknown.
2 C.A. Main (1989) estimate should not be relied upon, as a Qualified Person has not done sufficient work to classify the estimate as a current mineral resource.
3 Gold equivalent [AuEq] is used for illustrative purposes, to express the combined value of gold, silver, copper, molybdenum, and tungsten as a percentage of gold for the Revenue-Nucleus area (porphyry related) and gold, silver, copper, lead, and zinc as a percentage of gold for the Mount Freegold Area (epithermal related). The lower detection limit for silver in assay package GE_ICP40Q12 is 2 g/t, therefore any samples that returned <2g/t have been excluded from all AuEq calculations. No allowances have been made for recovery loss that would occur in a mining scenario. AuEq is calculated on the basis of US$1,500 per troy ounce of gold (Au), US$18.00 per troy ounce of silver (Ag), US$3.00 per pound of copper (Cu), US$9.00 per pound of molybdenum (Mo), US$1.00 per pound of lead (Pb), US$1.25 per pound of Zinc (Zn), and US$13.00 per pound of tungsten (W). 4 Table coordinates presented in NAD83 (Zone 8N); Azimuths presented relative to UTM Grid.
