VANCOUVER, Nov. 2, 2017 /PRNewswire/ - Triumph Gold Corp., (TSX-V: TIG) (OTCMKTS: NFRGF) ("Triumph Gold" or the "Company") is pleased to announce that prospecting and step out drilling to the east and west of the Revenue diatreme have been rewarded with significant new discoveries including:

  1. High-grade gold-rich porphyry mineralization in multiple drill holes in the Blue Sky Zone (Figure 1, Table 1, Table 2), east of the Revenue diatreme, including identification of visible gold in RVD17-01, and 57m of 1.72 grams/tonne (g/t) AuEq* at 1.08 g/t gold and 0.285% copper in RVD17-13.
  2. A corridor of high-grade, gold-rich, porphyry style mineralization over a strike length of 450m (including RVD1-13, previous bullet point) that extends from the eastern edge of the Revenue diatreme northeast into the Blue Sky Zone. Mineralization is open to depth and to the northeast where it appears to increase in grade.
  3. Identification of a robust porphyry related hydrothermal system responsible for dense stockwork veining, phyllic and potassic alteration and copper-gold mineralization from surface to 603m depth in a single drill hole collared 1.4 km west of the Revenue diatreme in the Keirsten Zone.
  4. Discovery of a new gold showing (Happy Creek showing) on the far eastern side of the Revenue/Nucleus 5.5 X 2.0 km soil/geophysical anomaly, 400m east of any historical drilling and over 1 km east of the Revenue diatreme.  The showing is defined with surface grab samples that grade up to 5.77 g/t gold and a 236m drill intersection with a length*** weighted average gold grade of 0.238 g/t.

Triumph Gold completed 12,904m of diamond drilling in 35 holes during 2017.  Results from 17 holes totalling 7,632m have been released to date.  The remaining results will be released in the coming weeks.

Motivation for Step Out Drilling

A primary objective of the 2017 drill program near Revenue was to demonstrate through systematic step outs that the Revenue diatreme is part of a larger porphyry system.  The idea was tested with drilling at the Blue Sky and Keirsten Zones which extend approximately 1 km to the east and west of the Revenue diatreme, respectively (Figure 1).  The motivation for the broad expansion of the exploration target at Revenue was identification of porphyry style high-grade copper-gold-silver and molybdenum mineralization that predates diatreme emplacement, in drill holes adjacent to the Revenue diatreme (noted below and Figure 1). 

  • RVD11-019: 70.48m (179.25 – 249.73m) 1.489 g/t Au, 0.219% Cu
  • RVD11-022: 55.45m (86.75 – 142.20m) 0.418 g/t Au, 0.191% Cu
  • RVD11-028: 162.36m (84.79 – 247.15m) 0.446 g/t Au, 0.218% Cu, 0.085% Mo.

While the diatreme is recognized as an exploration target itself, the possibility that it is surrounded by a porphyry with significant gold and copper grades remained largely untested until the 2017 drill program.

Porphyry Mineralization in the Blue Sky Zone

The Blue Sky Zone encompasses a multi-element soil anomaly that extends up to 1.5 km east of the Revenue diatreme (Figure 1).  Relogging of core from RVD11-019, 022 and 028 in 2016 identified two stages of mineralization, including an early stage of classic porphyry related stockwork veining with potassic alteration with good gold-copper-molybdenum grades (see above). Step out drilling in 2017 was designed to test for eastward extensions of that mineralization within the Blue Sky Zone soil anomaly.  Three drill holes that tested the Blue Sky Zone intersected significant porphyry style mineralization (Figure 1, Table 1, 2).

  • RVD17-013 was collared 350 metres northeast of drill holes RVD11-019, 22 and 28, and intersected 119m of copper-molybdenum-gold-silver porphyry style mineralization grading 0.60% CuEq*, with a 57m thick high-grade, gold-rich core grading 1.09% CuEq* at 1.083 g/t gold and 0.285% copper (Table 2).
  • RVD17-01 was collared 100 metres east of drill holes RVD11-19, 22 and 28 and intersected 148.58m of copper-molybdenum-gold-silver porphyry style mineralization. Average grades within the intersection include 39.58m of 0.40% CuEq* and 94.38m of 0.48% CuEq* (Table 2).
  • RVD17-03 was drilled from the same setup as RVD17-13 but in the opposite direction. It is interpreted to have just skimmed the edge of the mineralized zone, intersecting multiple short domains of porphyry style mineralization and alteration including 18.60m of 0.423 g/t gold and 0.105% copper (Table 2, 4).

Together with results from RVD17-12 (PR#17-12, October 19, 2017: 245m of 0.37 CuEq* with a 58.65 metre high-grade core grading 0.971 g/t Au and 0.218% Cu), and historical drill holes RVD11-19, 22 and 28, a corridor of high-grade, gold-rich, porphyry style mineralization is now demonstrated over a strike length of 450m. The geometry of the mineralized zone is not well understood, but at minimum it is open at depth and to the northeast where, based on results from RVD17-13, it appears to be increasing in grade.
