Vancouver, British Columbia--(Newsfile Corp. - January 30, 2020) -
Thunderstruck Resources Ltd.
(TSXV: AWE) (OTC:
THURF) (The "Company") is pleased to report significant assay results for the remaining diamond drill holes completed during
2019 on its Korokayiu Joint Venture zinc-copper VMS prospect. Based on the strength of these and previously reported 2019
drill results, together with other recent results from the project, the JV has applied to increase the tenement holdings by over
350%. Arrangements are underway to begin the next phase of drilling, which will be focused on scouting holes and completely
funded by the JV partner.
Highlights
Drill hole
WLK17
intersected
13.8% zinc (Zn), 2.94% copper (Cu), 114 grams-per-tonne silver (g/t Ag), and 1.08 g/t
gold (Au) over a drill core interval of 11 metres.
The hole was collared 80 metres east along strike from the Korokayiu
VMS Discovery Outcrop to infill and verify historical drill intercepts reported by Anglo Pacific Prospecting Ltd. ("Anglo") in
the 1970s.
Drill hole
WLK16A,
collared 120 metres south of WLK17, intersected
21.6% Zn, 2.0% Cu, 81 g/t Ag, and 0.42 g/t Au
over a drill core interval of 2.77 metres.
These highly encouraging results greatly elevate the potential of the eight additional, underexplored zinc-copper VMS
prospects along 15 kilometres of prospective geologic trend.
As VMS deposits commonly occur in clusters, the JV has applied to increase the tenement from 30 sq kms to 136 sq kms
to adequately bracket the district.
Bryce Bradley, Thunderstruck's President/CEO, stated
"Zinc grades have increased 2.5 times for two of our modern diamond
drill holes versus the historically reported Anglo drill intercepts. Our current drilling program has also shown a sizable
increase in copper, gold and silver grades relative to historical data. We are now in the process of securing a rig capable of
testing these showings further down dip as well as continuing to test them laterally. This next phase of scouting holes will help
to give size and direction beyond the historical discovery.
And since the Korokayiu program is fully funded, it gives
Thunderstruck the opportunity to advance its efforts on our other three 100%-owned projects in Fiji."

The Korokayiu tenement features approximately 15 kilometres of prospective geologic strike length, including eight additional,
underexplored zinc-copper VMS prospects (
see Thunderstruck News Release August 19, 2019
). The results of 2019 geologic
mapping and prospect assessment indicate that the geologic horizon and volcanic stratigraphy hosting the Korokayiu VMS
mineralization and other high-priority prospects may extend outside the current landholdings. VMS deposits worldwide
commonly occur in clusters within districts, with one or two large deposits and many smaller deposits/prospects.

The move to
expand the Korokayiu landholdings will allow the JV to capitalize on the potential for additional VMS discoveries.
The exploration program on Korokayiu is funded by Japan Oil, Gas and Metals National Corporation (JOGMEC), a Japanese
agency funded by the national government with the intent of discovering large-scale mineral deposits that will benefit Japanese
industry.

Drill hole
WLK17
intersected
13.8% zinc (Zn), 2.94% copper (Cu), 114 grams-per-tonne silver (g/t Ag), and 1.08 g/t gold
(Au) over a drill core interval of 11 metres
2
(Table 1 and Figure 1). WLK17 (-45
o
dip / 334
o
azimuth) was collared 80 metres
east along strike from the Korokayiu VMS Discovery Outcrop to infill and verify historical drill intercepts reported by Anglo. The
mineralization is hosted by intensely altered fragmental volcaniclastic dacite hosting massive sphalerite-chalcopyrite-pyrite
mineralization.
The WLK17 intercept is significant in that it represents the highest-grade drill intercept to date, current or historically reported,
from Korokayiu. WLK17 was in part designed to twin historic hole WLK4, drilled by Anglo over 40 years ago, which returned
assays of 5.5% Zn and 2.3% Cu over a drill core interval of 10 metres.

The fact that WLK17 returned a zinc grade 2.5 times
that of WLK4 underscores the importance of modern verification drilling at Korokayiu and its potential to add value to the project.
Drill hole
WLK16A,
collared 120 metres south of WLK17, was designed to test the depth extent of high-grade massive sulphide
mineralization intersected in Thunderstruck's recent 2019 drill hole
WLK14B,
and disseminated mineralization within
WLK14A
.
WLK16A
(-60
o
dip / 334
o
azimuth)
intersected fine-grained felsic volcaniclastic rocks hosting clastic semi-massive to massive
sphalerite-chalcopyrite-pyrite mineralization that assayed
21.6% Zn, 2.0% Cu, 81 g/t Ag, and 0.42 g/t Au over a drill core
interval of 2.77 metres
2
(Figure 2).
Similar to WLK17, drill hole WLK16A returned a zinc grade 2.5 times that of the historic
Anglo drill hole that it was designed to twin, WLK11, which returned 8.3% Zn and 2.8% Cu over a 2.1-metre drill core interval.

Drill hole WLK16B (-90

collared from the same setup did not intersect significant mineralization, similar to historic Anglo
drilling nearby

About Fiji
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.
