Vancouver, British Columbia--(Newsfile Corp. - September 27, 2017) - Thunderstruck Resources Ltd. (TSXV: AWE) ("Thunderstruck") is pleased to announce the results of 110 stream sediment Bulk cyanide Leach Extractable Gold (BLEG) stream sediment samples at its Rama Creek Copper-Gold (Cu-Au) Prospect in Fiji. 2017 Phase 1 sampling confirms the historic Rama Creek Au-Cu geochemical anomaly, and defines new Au-Ag geochemical anomalies at Senikura Creek and Rama Creek north.
The Company has received final results for 110 BLEG stream sediment geochemical samples collected from its Rama Creek Porphyry Cu-Au prospect during May 2017 (Phase 1). Sampling at Rama Creek was designed to follow-up and provide confirmation of historic copper and gold in stream and auger soil anomalies discovered in the headwaters of Rama Creek. Historic 1974 diamond drilling reported by Australian Anglo American Ltd (Anglo) at Rama Creek targeted a magnetic high and Induced Polarization (IP) chargeability geophysical anomaly and intersected significant porphyry copper mineralization, with vertical drill hole "DDH1" returning a 244 metre interval between depths of 6 and 250 metres averaging 0.22% Cu and ending in mineralization. No additional diamond drilling has been completed at Rama Creek since Anglo's initial discovery program.
"We believe the Rama Creek prospect has excellent potential for expansion of the historically reported zone of porphyry Cu-Au mineralization," commented Bryce Bradley, Thunderstruck President and CEO, "as well as the discovery of additional mineralization through follow-up of new Cu-Au stream geochemical anomalies as presented in detail below."
2017 Phase 1 BLEG Sample Results
The current BLEG stream sediment sampling by Thunderstruck personnel comprise 110 samples collected within the headwaters and tributaries of Rama and Senikura creeks over an approximately 16 km-square area. Cyanide leach determined values for gold (110 samples), silver (47 samples) and copper (47 samples) ranging from below detection up to 16 ppb (parts per billion) Au (95th percentile = 14 ppb Au), 0.57 to 28 ppm (parts per million) Cu (95th percentile = 21 ppm) and 1 to 168 ppb Ag (95th percentile = 94.5 ppb Ag).
Stream sampling at Rama Creek within the area of historic Anglo drilling returned seven (7) samples ranging from 11 to 16 ppb Au and four (4) samples ranging from 19 to 28 ppm Cu, which define a 400 x 500 metre anomaly (Rama Creek Cu-Au target), confirming work by previous explorers.
West of Rama creek, approximately 300 metres west of the Rama Creek Cu-Au target, two (2) stream samples returned silver (Ag) values of 145 and 99 ppb Ag, in addition to 11 ppb Au. This anomaly represents a new geochemical target not associated with historically identified Cu-Au anomalies at Rama Creek. Similarly, a single stream sample 1 km northeast of the Rama Creek Cu-Au target returned 168 ppb Ag; the highest silver-in-stream value returned from Phase 1 sampling.
At the headwaters of Senikura Creek, within the centre of the Senikura magnetic low anomaly, a single stream sample returned 16 ppb Au and 84 ppb Ag. The gold value is significant in that it is the highest gold value returned from Phase 1 sampling, in conjunction with 16 ppb Au stream values recovered from the creek draining Anglo drill hole DDH 1, and represents a distinct combined Au-Ag geochemical and magnetic low target located 1 km southeast of the Rama Creek Cu-Au target.

About Rama Creek
At the Rama Creek prospect, hornblende feldspar porphyritic tonalite intrudes mafic to intermediate volcanic rocks of the Wainimala Group. Porphyry Cu-Au mineralization occurs in both porphyritic intrusives and surrounding Wainimala volcanics. Mineralization is associated with widespread propylitic and localized potassic alteration and comprises quartz-stockwork fracture controlled pyrite, magnetite, malachite, chalcocite, covellite and chalcopyrite-bornite.
Drilled porphyry Cu-Au mineralization at Rama Creek is coincident with an approximately 5 km circumference arcuate magnetic high airborne magnetic geophysical anomaly in the centre of which occurs a 1.4 km diameter circular magnetic low anomaly in the headwaters of Senikura Creek. The Rama and Senikura creek magnetic anomalies define two high priority target zones which were the subject of current and future Rama Creek exploration by Thunderstruck.
The Rama Creek porphyry Cu-Au prospect was discovered in 1971 by Barringer Fiji Ltd. In 1974 Australian Anglo American Ltd (Anglo) completed 4 vertical diamond drill holes totalling 802.4 metres at Rama. Drill hole DDH 1 targeting the centre of a combined copper-in-soil, magnetic and Induced Polarization (IP) chargeability geophysical anomaly intersected porphyry intrusive that returned a 244 metre interval averaging 0.22% Cu, between 6 and 250 metres downhole; including 72 metres averaging 0.23 grams-per-tonne (g/t) Au between 6 and 78 metres downhole. Drill hole DDH 1 terminated in mineralization at 250 metres vertical depth. Drill hole DDH 3 collared approximately 100 metres to the east of DDH 1 returned 60 metres averaging 0.098% Cu from a depth of 6 to 66 metres within pyrite-chalcopyrite mineralized volcanic rocks.
Subsequent 1988 exploration by Southern Pacific Resources (Fiji) Ltd. included auger soil and stream sediment geochemical sampling. 100 metre-spaced ridge and spur copper in auger soil values in the area of the previous Anglo diamond drilling ranged from 675ppm to 0.64% Cu defining an approximately 700 metre x 500 metre anomalous zone. Anglo drill holes DDH 1 and DDH 3 are coincident the 316ppb and 146 ppb Au in soil anomalies, respectively. At Senikura Creek, an 800 metre length ridgeline gold in soil anomaly was defined that returned values ranging from 69 to 511 ppb Au (Senikura West), while 1.5 km to the east, a 1 km length gold in soil returned values ranging from 61 to 74 ppb Au (Senikura East).

Mr. Raffle has reviewed the portion of the technical content of this news release as it relates to the Rama Creek Prospect. During 2017 at stream sediment samples were submitted to Australian Laboratory Services Pty. Ltd (ALS) labs Brisbane for Bulk Leach Extractable Gold (BLEG) determination of gold, silver and copper. Selected samples were also submitted for multi-element geochemical analysis by Inductively Coupled Mass Emission Spectroscopy (ICP-ES). Thunderstruck has relied on the external QA/QC of ALS which included the insertion of standard, blank and duplicate samples at a rate of 10% into the sample stream to confirm the accuracy of the reported results.
