Vancouver, British Columbia--(Newsfile Corp. - February 13, 2018) - Thunderstruck Resources Ltd. (TSXV: AWE) ("Thunderstruck") is pleased to provide results from its recent exploration conducted at the Liwa Creek Gold Prospect in late 2017.
Liwa Creek is part of a 148 sq km property held by Thunderstruck in Fiji, located 50km south of the Vatukoula gold mine, which has produced 7 million ounces of gold. Fiji is located on the Pacific Ocean's Ring of Fire, which contains many of the world's major gold and copper deposits, including Lihir and Grasberg *.
Between November and December 2017 Thunderstruck crews completed 520m of hand trenching in four (4) separate areas of the Jensen and Liwa Ridge gold showings resulting in the collection of 117 trench channel samples. In addition, 123 prospecting rock grab, 110 ridge-and-spur auger soil, and 47 BLEG stream sediment samples were collected from the Liwa and Vatuvatulevu creek areas, which include the Liwa Ridge, Jensen's, and Gun gold showings.
Commenting on the results, President/CEO Bryce Bradley notes that "Multiple examples of significant gold mineralization, as well as extensive anomalies, have now been uncovered across the expanse of our property. In particular, these results show that our Liwa and Jensen's discoveries are shaping up to be intriguing gold targets. Now that we have all permitting in place, we're entertaining joint venture opportunities to aggressively advance this exciting asset."
Jensen's Showing
Thunderstruck prospecting crews successfully located and sampled the historic Jensen's gold showing on Wainamoli Creek with two rock grab samples returning high grade gold values of 36.1 and 31.8 g/t Au; including 12.5% and 6.8% Pb (lead), respectively (Table 1). A total of 21 rock grab samples were collected along a stretch of the Wainamoli Creek outlining a 300m zone of anomalous gold values; including 8 samples returning greater than 0.2 g/t Au, and a series of discontinuous rock outcrop channel samples collected over a distance of 35m averaging 0.38 g/t Au.

Excavation of a 261m E-W trending trench at the Jensen's gold showing was hampered by deep weathering along the western half of the trench and deep stream gravels along Wainamoli Creek. The 29.1m interval between 189.5 and 218.6 m uncovered a zone of weathered locally quartz-sulphide mineralized and intensely sericite altered and limonitic mafic volcanic rock. The highest trench value within this interval returned 0.1 g/t Au over 2.8m.
The relationship of the trenched intervals to the true width of mineralization is not known. However, field relationships suggest mineralized zones may trend NE to ENE sub-parallel to the major drainage of Wainamoli Creek. Anomalous gold values within Jensen's trench are therefore interpreted to define the western limits of a poorly exposed zone of locally high grade gold mineralization to the east.
Liwa Ridge Showing
At the Liwa Ridge Showing two trenches (Liwa North and South) were excavated having lengths 124m and 110m, respectively; separated 200m along strike and 100m vertically.
The Liwa South trench returned, 1.2 g/t Au over 26.5m (from 5 to 31.5m, 6.2m un-sampled*), including 3.6 gram-per-tonne (g/t) gold (Au) over 4.2m (from 5 to 9.2m), within a broader anomalous gold zone averaging 0.61 g/t Au over 71.3m (from 0 to 71.3m, 14.7m un-sampled). Mineralization is open to the east with the first trench sample returning 0.33 g/t Au over 5m (Table 2).
The Liwa North trench returned 0.30 g/t Au over 31m (from 36 to 67m) within a broader anomalous gold zone averaging 0.24 g/t Au over 67m (from 36 to 103m, 8.4m un-sampled). Mineralization is open to the east under thick scree cover. To the west the trench crosses the 6m wide Liwa Creek drainage. Limited trench sampling on the west side of Liwa Creek did not return anomalous gold values, however select outcrop grab samples there yielded anomalous gold values of 0.11, 0.15 and 0.52 g/t Au.
Geologic mapping confirms the presence of a sub-vertical 60m wide zone of hematite-silica-pyrite altered mafic volcanic rocks over a 400m strike and 100m vertical extent between the Liwa and Noda creek drainages. The zone is open to the north, south and east under scree and soil cover.
A total of 46 rock grab samples were collected over a 600 x 200 m area surrounding the Liwa Ridge showing. Gold values ranged from below detection up to 8.13 g/t Au and 0.19% Pb, with a total of 7 samples returning greater than 0.5 g/t Au. Prospecting has extended gold mineralization 120m south of Liwa Ridge into the Noda Creek drainage where rocks grab sampling returned values of 1.27 and 3.54 g/t Au in outcrop.
Auger soil sampling along Liwa Ridge revealed robust gold in soil values (0.64 g/t Au) coincident with trench-confirmed mineralization. An additional two auger soils collected at distances of 5 and 20m beyond the eastern limit of the Liwa South trench returned 0.24 and 0.55 g/t Au, respectively (the three highest gold-in-soil values to date); indicating potential to expand the mineralized zone eastward.
