Thunderstruck Drills 14.5% Zinc over 6.3 Metres at Its Korokayiu Copper-Zinc VMS Prospect
Vancouver, British Columbia--(Newsfile Corp. - December 11, 2019) - Thunderstruck Resources Ltd. (TSXV: AWE) (OTC: THURF) (The "Company") is pleased to report that the first two drill holes on its Korokayiu Joint Venture (JV) zinc-copper volcanogenic massive sulphide (VMS) prospect confirm historic results reported by Anglo American over 40 years ago which outlined a significant zinc-copper-silver-gold VMS system. Assays are pending for another 5 holes.
Based on these positive results, the joint venture partner JOGMEC is presently working with Thunderstruck on details of an aggressive 2020 drill program.
Drill hole WLK14B intersected 14.5% Zinc (Zn), 2.35% Copper (Cu), 111 grams-per-tonne Silver (g/t Ag), and 0.66 g/t Gold (Au) over a drill core interval of 6.31 metres1; within a broader zone of mineralization returning 9.5% Zn, 1.87% Cu, 55 g/t Ag, and 0.48 g/t Au over a 10.55-metre core interval (Table 1 and Figure 1). WLK14B (-60o dip / 334o azimuth) was drilled beneath the Korokayiu VMS Discovery Outcrop to verify historical drill intercepts reported by Anglo American. The mineralization is hosted by intensely altered fragmental volcanoclastic dacite hosting massive sphalerite-chalcopyrite-pyrite mineralization.
Drill hole WLK14A was designed to test the depth extent of high-grade massive sulphide mineralization intersected in WLK14B 40 metres down dip on section. WLK14A (-90o dip) intersected hanging wall basalt-andesite rocks directly overlying a shear and faulted contact zone beneath which dacitic volcanoclastic rocks hosting disseminated chalcopyrite-pyrite mineralization assayed 2.0% Cu, 0.11% Zn, 60 g/t Ag, and 0.51 g/t Au over a drill core interval of 3.35 metres1, within a broader zone of mineralization assaying 1.2% Cu, 0.3% Zn, 28 g/t Ag, and 0.23 g/t Au over 8.38 metres.
Bryce Bradley, Thunderstruck's President/CEO, stated, "Thunderstruck is pleased with the initial drill results at Korokayiu which have confirmed the presence of high grade copper-zinc massive sulphide mineralization. With the last drilling on this prospect occurring over 40 years ago, and with no historic drill core remaining, we knew our first task would be to verify some of the key historically reported drill intercepts and provide new drill core to bring the significance of the Korokayiu discovery to light. We look forward to receiving additional drill results in the coming weeks that include further drilling on this section and step-outs to the east."

The 2019 Korokayiu Joint Venture (JV) zinc-copper volcanogenic massive sulphide (VMS) prospect diamond drill program comprised 7 drill holes totaling 904 metres designed to verify the presence of historically reported copper-zinc massive mineralization and further test the extent of the deposit area. The 2019 diamond drill program has now paused for the holiday break and is expected to resume in early January, 2020. The drilling is funded by Japan Oil Gas and Metals National Corporation (JOGMEC), a Japanese company funded by the national government with the intent of discovering large-scale mineral deposits that will benefit Japanese industry.
"JOGMEC is currently in Fiji with Thunderstruck planning our 2020 drill program with a minimum expenditure of $1,500,000 to further test the depth and size of Korokayiu," Bradley added. "Positive results may accelerate the program and increase expenditures."

Viti Levu, the main island of Fiji, has a long mining history. It is on the prolific Pacific Ring of Fire, a trend that has produced numerous large deposits, including Porgera, Lihir and Grasberg. The island of Viti Levu hosts Namosi, held by a joint venture between Newcrest and Mitsubishi. Newcrest published Proven and Probable Reserves for Namosi of 1.3 billion tonnes at 0.37% Cu and 0.12 g/t Au (5.2M ounces Au and 4.9M tonnes Cu). Namosi is now undergoing environmental assessment as part of the permitting process. Lion One Metals is now developing its Tuvatu Project, with Indicated Resources of 1.1 million tonnes at 8.17 g/t Au (294,000 ounces Au), and Inferred Resources of 1.3 million tonnes at 10.6 g/t Au (445,000 ounces Au). The Vatukoula Gold Mine has been operating for 80 years, producing in excess of 7 million ounces.

Methodology and QA/QC
The analytical work reported on herein was performed by Australian Laboratory Services Pty. Ltd. (ALS) at Perth, WA. ALS is an ISO-IEC 17025:2017 and ISO 9001:2015 accredited geoanalytical laboratory and is independent of the Thunderstruck Resources and the QP. Drill core samples were subject to crushing at a minimum of 70% passing 2 mm, followed by pulverizing of a 250 gram split to 85% passing 75 microns (PREP-31). A 0.25 gram sample pulp was then subject to 4-acid (HF-HNO3-HClO4) digestion and analysis via 33 element ICP-AES analysis (ME-ICP61) for base metals and silver, and 30 gram fire assay fusion (Au-AA25) for gold determination. Base metal over limit values returning greater than 1%, or greater than 100 g/t for silver, were analyzed by four-acid digestion of a 0.40 gram sample pulp, followed analysis via ICP-AES (ME-OG62).
Thunderstruck Resources follows industry standard procedures for the work carried out on the Korokayiu prospect, with a quality assurance/quality control (QA/QC) program. Blank, duplicate and standard samples were inserted into the sample sequence sent to the laboratory for analysis. Thunderstruck Resources detected no significant QA/QC issues during review of the data. Thunderstruck Resources is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data referred to herein.
