Triumph Gold Announces Discovery of High-Grade Gold in Least-Explored Portion of the Revenue Deposit Including a 7-metre Interval Grading 15.0 grams/tonne Gold
November 15, 2017
Vancouver, British Columbia: November 15, 2017. Triumph Gold Corp., (TSX-V: TIG) (OTCMKTS: NFRGF) (“Triumph Gold” or the “Company”) is pleased to announce that exploration drilling in an underexplored portion of the Revenue soil anomaly intersected high-grade gold mineralization in granite south of the Revenue diatreme. Highlights from diamond drill hole RVD17-14 include:
- Visible gold over a 5-metre interval (129 – 134 m).
- Contained within a 7-metre interval (129 – 136 m) of gold-silver-copper mineralization with a length*** weighted grade of 15.0 grams/tonne (g/t) gold (see below).
- Including a 1-metre interval (129 – 130 m), re-assayed three times, grading between 45.0 and 81.3 g/t gold.
- The drill hole was collared in the immediate catchment of a renowned placer creek (Revenue Creek), and the mineral association, coarse gold with bismuthinite, is the same as the placer gold.
RVD17-14 (Table 1) was drilled within a 1.2 X 0.5 kilometre multi-element, gold-rich, soil anomaly on a broad ridge that separates Whirlwind Pup and Revenue Creeks on the southern side of the Revenue diatreme. It is in the immediate catchment of the Revenue Creek placer gold deposit, renowned for having had one of the most gold-rich channels in the Dawson Range. Historical exploration within the anomaly documented two gold showings, suggesting that the entire area is prospective for high-grade lode gold, and may be the source for much of the abundant placer gold found in Revenue Creek:
- the Klaus Zone which is immediately above the historical (pre-placer mining) confluence of Whirlwind Pup and Revenue Creek; and
- the Guder Zone, which is approximately 400 metres past the confluence, up the ridge to the south.
Historical assay results for the two zones are noted below and in Table 3.
RVD17-14, the first modern drill hole in the area, was collared in the Guder Zone, 200 metres away from any historical trenching or drilling, within an outstanding and previously untested portion of the gold-in-soil anomaly, which includes four high grade samples (3.37 g/t, 2.26 g/t, 0.83 g/t and 0.88 g/t). The drill hole intersected a seven-metre-long interval (129 – 134 m) of strong gold-silver-copper mineralization with gold disseminated within intergrown pyrite-arsenopyrite-chalcopyrite-bismuthinite and carbonate veins. The interval includes a 5-metre section with visible gold.
The tenor of gold mineralization in RVD17-14 is high as confirmed by repeated assay results, however, the results indicate a pronounced nugget effect. To reduce the nugget effect Table 2 includes the averaged results from repeat fire assays (with gravimetric finishes for Au>10 g/t) See the bottom of the news release for a table of all gold results from the high-grade interval.

Historical Exploration in the Vicinity of RVD17-14
The 1.2 X 0.5 km soil anomaly between Whirlwind Pup and Revenue Creek has seen less drilling that any other area near the Revenue diatreme. Limited historical exploration documented significant concentrations of gold in the Klaus and Guder zones (Main and Duke 1987), including:
- trench samples in the Klaus Zone grading up to 32.98 g/t Au over 20 cm; 14.3 g/t over 1 m, and 3.67 g/t over 1 m;
- trench samples in the Guder Zone grading up to 20.24 g/t Au over 6.1 m; and
- high-grade gold in drill intersections from the Guder Zone (Table 3).

Other Notable Intersections in RVD17-14
In addition to the high-grade gold intersection in RVD17-14 there were also two other notable mineralized intervals (Table 4):
- 29.79 metres (185.00 – 214.79m) of 0.46 g/t AuEq* in rocks with polyphase porphyry veining and potassic alteration at the contact between granite country rock and the Revenue diatreme.
- 6 metres (331.00 – 337.00 m) of 0.73 g/t AuEq* in sulfide-matrix hydrothermal breccia within the Revenue diatreme.
The 29.79 metres of porphyry mineralization on the margin of the diatreme add to the body of evidence (see PR17-12, PR17-13) that show a broad, at least 2.85 km long, mineralized porphyry at Revenue, which is cored, and cross-cut, by the Revenue diatreme.

Paul Reynolds, Triumph Gold’s President and CEO comments “We have only just begun to explore this highly prospective area, which hasn’t been drilled since 1984, and with our very first hole we intersected the highest-grade gold ever found at Revenue. The discovery of coarse gold in RVD17-14 is especially compelling because of its location in the headwaters of Revenue Creek, one of the Dawson Range’s most renowned placer creeks.”

Full Table of Gold Analyses
Each of the five high-grade gold samples reported from RVD17-14 (129-136 m) underwent two sets of fire assay (Table 5) analyses and an additional metallic screen analysis (Table 5).

Methods and Qualified Person
Drill core samples ranged between 1 and 2 meters length and were cut at Triumph’s core logging facility on the Freegold Mountain Property. The samples were analyzed by ALS Global of North Vancouver, British Columbia. They were prepared for analysis according to ALS method PREP35: each sample was crushed to 70% passing 2mm and a 250g split was pulverized to better than 95% passing 106 micron mesh. Gold was tested by fire assay with atomic absorption finish on a 30g nominal sample (method Au-AA23), and samples that tested over 10 g/t Au were retested using fire assay with a gravimetric finish (method Au-GRA21). An additional 35 elements were tested by ICP-AES using an Aqua Regia digestion (method ME-ICP41), over limit samples for copper were retested using the same technique but with assay grade Aqua Regia digestion and a higher range of detection (method ME-OG46). 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 one in ten samples submitted by Triumph Gold was a blank or certified reference standard. QAQC samples that returned unacceptable values triggered investigations into the results and reanalyses of the samples that were tested in the batch with the failed QAQC sample. Where contamination or analytical error were suspected the original data were discarded and superseded by the results of the reanalyses.
The five samples reported in Table 5 were part of a 19-sample batch that included six QAQC samples. The samples were delivered by Triumph Gold personnel directly to the ALS prep-lab in Whitehorse. All of the samples were tested by the methods discussed in the previous paragraph and the five samples listed in Table 5 were also tested using the gold screen metallic technique (method Au-SCR24). For this technique the sample was prepared by passing up to 1000g of pulp though a 100 micron mesh and testing both the material that passed through the screen (“-“ fraction) and the material that remained on the screen (“+” fraction). The entire + fraction was tested by fire assay with a gravimetric finish, and the – fraction was homogenized and two 50g splits were tested by fire assay with AAS finish and the results were averaged. The gold values of the + and – fractions were combined in a weighted average to give the total gold content of the sample.
