Paul Reynolds, Triumph Gold’s President and CEO, comments, “RVD18-19 contains a truly exceptional intersection. Not only does it represent the longest and highest grade intersection in the Blue Sky Porphyry to date, but it is one of the highest grade intersections ever made in a porphyry system in the Yukon. At 565.6 gram metres**** gold equivalent*, it is likely to be one of the best intersections made on a gold exploration property this year. I congratulate our technical team for their perseverance and success in testing previously untested ground surrounding the Revenue and Nucleus deposits.”
Blue Sky Porphyry
Since 2016 Triumph Gold’s exploration on the Freegold Mountain Property has been focused on the six-kilometre-long, multi-element soil and geophysical anomaly that encompasses the Revenue and Nucleus areas. Within the anomaly, the Blue Sky Zone covers a broad area extending 2.3 kilometres east of the Revenue diatreme (Figure 1) to the eastern margin of the anomaly. It was drill tested in 2017 with significant intersections made in RVD17-13 (57.00 metres of 1.08 g/t Au, 6.6 g/t Ag, 0.285% Cu and 0.02% Mo from 112.00m; Table 1) and RVD17-01 (Table 1). Three previously released 2018 drill holes (see NR18-08 dated Aug. 23; Table 1) successfully targeted the Blue Sky Porphyry and demonstrated both high-grade and contiguous mineralization over up to 202.10 metres (RVD18-17, which included 125.13 metres of 1.24 g/t Au, 7.0 g/t Ag, 0.31% Cu, and 0.01% Mo; Table 1). With RVD18-19, RVD18-20 and RVD18-21, described in this news release, the size and grade of the Blue Sky Porphyry continues to grow. RVD18-19 contains the longest*** intersection (316.00m of 1.09% CuEq*; Table 1), the highest grade composite (79.75m of 2.48 g/t Au, 0.38% Cu, 6.9 g/t Ag and 0.02% Mo; Table 1), and the highest grade gold in a single assay (39.4 g/t Au from 376.60 – 377.60m) to date.

High-grade, gold-rich mineralization in the Blue Sky Porphyry is demonstrated over 180 meters in a NE-SW direction and occupies the north-eastern extent of a 500 metre long corridor of well mineralized rock that includes the newly defined WAu breccia (e.g. 76.34 metres of 1.40 g/t Au, 9.2 g/t Ag, 0.21% Cu and 0.032% Mo in RVD11-19; see PR#18-07, dated July 21, 2018), and porphyry related stockwork style mineralization (e.g. 238.10 metres of 0.31 g/t gold and 0.13% copper in RVD11-22). The high-grade zone is modeled as an irregular shaped body with a south or south-east dipping upper surface that is open along strike to the northeast, west, and downdip to the south and southeast. The 500 metre-long corridor is contained within a 3.6 kilometre zone of porphyry mineralization that extends from the Happy Creek showing (269.00 metres of 0.29 g/t AuEq* in RVD17-09, see PR#17-13, dated Nov. 2, 2017) to the Keirsten Zone (100 metres of 0.32 g/t AuEq* in KZ18-01, see PR#18-07, dated July 21, 2018). The broader zone of porphyry mineralization is flanked to the west by the Nucleus epithermal gold deposit, and cross-cut by a locally well mineralized diatreme (the Revenue Diatreme).
Mineralization associated with the Blue Sky Porphyry is hosted in the Mid-Cretaceous Revenue granite and in late-syn-mineral quartz-feldspar-porphyry dykes. It consists of chalcopyrite and molybdenite in quartz veins, hydrothermal breccia matrix, and disseminated in hydrothermally altered granite and quartz-feldspar porphyry dykes. The most intense mineralization is associated with strong potassic (K-feldspar grading outwards into biotite) alteration. A set of late quartz-carbonate veins are concentrated within the main mineralized zone and contain variable amounts of chalcopyrite, molybdenite, galena, sphalerite, bismuthinite, and visible gold. The porphyry is gold-rich throughout, but the late quartz-carbonate veins represent an important second stage of gold enrichment.
Ongoing Exploration of the Blue Sky Porphyry
The high-grade mineralization identified in the Blue Sky Zone continues to be a focus of exploration activity:
Triumph Gold’s 2018 Freegold Mountain Property drill campaign, which began in late March, is now complete. Geophysics, trenching and soil sampling programs are expected to continue until early October. Triumph Gold has released the results from 9,672 metres of diamond drilling in the Keirsten Zone, Revenue East, and the Blue Sky Zone. Drill results from these zones have been released in their entirety. Future news releases will focus on grassroots exploration drilling in the Guder (1,352 metres) and Granger (1,014 metres) zones, exploration and resource drilling at Nucleus (4,159 metres), and the inaugural drilling of the Irene epithermal vein (1,369 metres).

* Gold equivalent [AuEq], and copper equivalent [CuEq] are used for illustrative purposes, to express the combined value of gold, silver, molybdenum and copper as a percentage of gold or copper. No allowances have been made for recovery losses that would occur in a mining scenario. AuEq and CuEq are calculated on the basis of US$3.00 per pound of copper, US$16.00 per pound of molybdenum, US$1,250 per troy ounce of gold and US$16.00 per troy ounce of silver.

*** Length/interval refer to drill hole intercept. True widths have not been determined.
**** Gram metres are a metric used to compare the relative quality of drill intersections that vary in grade and length. In this press release gram-metres are calculated using the following equation (AqEq*[g/t] x Intersection Length*** [metres]).
Methods and Qualified Person
Drill core samples ranged between 1 and 2 metres length and were cut at Triumph’s core logging facility on the Freegold Mountain Property. 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 FAA313), and samples that tested over 10 g/t Au were retested using 50g screened metallics (GO FAS50M), which uses a combination of AAS, ICP-AES and gravimetric finishes to determine gold contained in both a fine and coarse fraction after being sieved through 106 mesh. An additional 35 elements were tested by ICP-AES using a four-acid digestion (method GE ICP40B), over limit samples for copper were retested using the same technique but with assay grade four acid digestion and a higher range of detection (method GA AAS42S). 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: at minimum three quality control samples, consisting of blanks, certified reference standards and duplicates, were blindly inserted into each 75 sample batch. QAQC samples that return unacceptable values trigger investigations into the results and reanalyses of the samples that were tested in the batch with the failed QAQC sample.
