The Revenue Deposit area is road accessible and centered across, and encompasses, Revenue Creek (Figure 1), a legendary placer gold creek in the Dawson Range. It occupies the central and eastern portion of a 24 km2 gold, copper and molybdenum soil anomaly with values that exceed 1,000 ppb gold and 500 ppm copper. The Nucleus deposit is located 2.5 km to the west of Revenue within the same multi-element soil geochemical anomaly (Figure 2).

A total of 8,219 metres of diamond drilling in 15 diamond drill holes was completed in the Revenue area in 2017. The focus of exploration at Revenue was shifted from the diatreme to the surrounding country rock, which was drill-tested with systematic, up to 1.3 km, step outs on each side of the diatreme. The program was successful in demonstrating that a broad area surrounding the diatreme is prospective for gold-rich porphyry mineralization. Highlights include:
- Identification of porphyry style mineralization over a greater than 4 km strike length, from Nucleus 2.5 km west of the diatreme, to the Blue Sky Zone, east of the diatreme.
- Definition of a 450-metre-long zone of high-grade, gold-rich porphyry mineralization in the Blue Sky Zone east of the diatreme. This zone is open in both directions along strike and to depth. Intersections include:
- RVD17-13 (88-207m) with 119 metres of copper-molybdenum-gold-silver porphyry style mineralization grading 0.60% CuEq*, including a 57 metre thick (112 – 169m) high-grade, gold-rich core grading 1.09% CuEq* at 1.083 g/t gold and 0.285% copper. See PR17-13 for more information.
- RVD17-12 with 245 metres of copper-molybdenum-gold-silver porphyry style mineralization grading 0.37% CuEq, including a 58.65 metre high-grade, gold-rich core grading 0.94% CuEq* at 0.971 g/t gold and 0.218% copper. See PR17-12 for more information.
- Discovery of the highest-grade gold ever found in drillcore at Revenue, with assays grading up to 81.3 g/t Au over a meter within a seven-metre-long interval (129 – 136 m) of strong gold-silver-copper mineralization grading 15.04 g/t Au, 7.2 g/t Ag and 0.113% Cu with gold disseminated within intergrown pyrite-arsenopyrite-chalcopyrite-bismuthinite and carbonate veins. See PR17-14 for more information.
- Identification of a new gold showing (Happy Creek showing) 1.1 kilometres east of the Revenue diatreme and 400m east of any historical drilling. The showing was tested with two surface samples that graded 5.77 and 3.76 g/t gold, and ten one- to two-metre-long intersections in RVD17-09 that graded above 1 g/t gold. See PR17-13 for more information.
- 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. See PR17-13 for more information.
* Copper Equivalent [CuEq, AuEq] is used for illustrative purposed, to express the combined value of copper, gold silver and molybdenum as a percentage of copper or gold. No allowances have been made for recovery losses that would occur in a mining scenario. CuEq and AuEq are calculated on the basis of US$3.10 per pound of copper, US$1,305 per troy ounce of gold, US$17.40 per troy ounce of silver and US$7.00 per pound of molybdenum oxide.
2018 Exploration Plan
Triumph Gold has a fully funded approximately 3 million dollar exploration plan for the 2018 seasons. The focus of exploration will be on the newly discovered zones of porphyry mineralization surrounding the Revenue diatreme, as well as targeting areas prospective for further expansions. New targets within the Revenue area include zones that have seen highly successful historical near-surface gold exploration but have never been explored for deeper porphyry related mineralization (e.g. Granger Zone, Figure 3).
