This profile is part of a paid investor education campaign.*

Overview

Thunderstruck Resources Ltd. (TSXV:AWE) (OTC:THURF) is developing a diverse portfolio of zinc, copper, silver and gold properties on the main island of Fiji, Viti Levu. Thunderstruck’s Fijian property portfolio covers nearly four percent of the main island and includes four main assets; the Korokayiu and Nakoro high grade zinc-copper volcanogenic massive sulphide (VMS) projects, the Liwa Creek gold project and the Rama Creek copper-gold porphyry project.

Thunderstruck recently signed a joint venture agreement with Japan Oil, Gas and Metals National Corporation (JOGMEC), who can earn a 70 percent interest in the Korokayiu VMS project by spending C$3.5 million in exploration. With Thunderstruck as operator, they intend to aggressively advance Korokayiu over the next three years with drilling planned for 2019.

Both the Nakoro and Korokayiu zinc-copper VMS projects are the site of successful historical drilling by Australian Anglo Pacific Ltd. (Anglo), with a historical resource of 11.6% Zn, 0.5% Cu and 8% Zn and 2% Cu respectively.

Beginning in July 2017, Thunderstruck commenced a series of exploration programs on the Liwa Creek and Rama Creek properties. The results of this work showcased the discovery of widespread gold mineralization at Liwa Creek as well as a confirmed large porphyry system and gold mineralization at Rama Creek. Thunderstruck has been conducting geologic mapping, geochemical, and IP geophysical programs on its Liwa Creek and Rama Creek properties to establish future drill targets

Thunderstruck is managed by an experienced team of geology, mining and financial professionals. Co-founding directors Brien Lundin and Bryce Bradley have a long history of raising capital and other strategic roles in the natural resource sector to support the advancement of discoveries like their current Fijian projects.

Recent additions to the Board and Advisory Board include Lawrence Roulston and Tookie Angus, both seasoned professionals with a wealth of technical and capital markets successes behind them. The company’s Country Manager, Moape Navia, has worked in several capacities in the Fijian mining industry, including 15 years at the Mineral Resource Department as Senior Technical Assistant and Mining Inspectorate Officer, and manages all facets of governmental and landowner relations.

Mining in Fiji

When most people think of Fiji, mining usually isn’t the first thing that comes to mind. However, mining in the South Pacific nation has been ongoing since the opening of the Emperor (now Vatukoula) gold mine in 1934.

As one of the most developed economies in the Pacific, Fiji is served by a pro-mining government who has a reasonable royalty (five percent gross profits) and tax structure (20 percent corporate). There is also a large skilled workforce and low political, sovereign and social risks. Fiji is close to Asian markets and the main island of Viti Levu has excellent infrastructure including a deep-water port and hydroelectric dam. The island archipelago is located on the Pacific Ocean’s Ring of Fire, a 40,000-kilometer arc of tectonic activity along which contain many of the world’s major gold and copper deposits. This includes Papua New Guinea’s Grasberg mine, the world’s largest gold mine and second largest copper mine; and Lihir containing proven and probable reserves of 23 million ounces gold at a grade of 2.3 g/t gold.

The highly prospective “Ring of Fire”

The Vatukoula gold mine, which started operating 80 years ago, is still in operation 50 kilometers north of Thunderstruck’s assets, and has produced more than seven million ounces of gold with 2013 reported proven and probable reserves of 750,000 ounces gold at a grade of 7.77 g/t gold; and combined measured and indicated resources of 2.7 million ounces gold at 7.1 g/t gold.

In addition to gold, Fiji also hosts several undeveloped major porphyry copper-gold deposits. Australian miner Newcrest, along with joint venture partners that include Mitsubishi Materials Corp., is developing its copper-gold project immediately adjacent to Thunderstruck’s properties. The Namosi project, one of the largest undeveloped copper resources in the world, contains a 1.3 billion tonne proven and probable reserve of 5.2 million ounces gold and 4.9 million tonnes copper at a grade of 0.12 g/t gold and 0.37 percent copper; in addition to a 1.8 billion tonne indicated resource containing 6.2 million ounces gold and 6.2 million tonnes copper at 0.11 g/t gold and 0.35 percent copper3.

Key Properties

Korokayiu Zinc-Copper Project

Thunderstruck Resources’ flagship project is the Korokayiu zinc-copper VMS project. The property is approximately 10 kilometers from the south coast of the main island and 50 kilometers by modern highway from the deep-water port at the Fijian capital of Suva. The property has a 15-kilometer strike length that includes eight underexplored targets. It remains open along strike and depth.

In February 2019, Thunderstruck signed a joint venture agreement with JOGMEC who can earn a 70 percent interest in the property by spending C$3.5 million on exploration by March 31, 2022. Thunderstruck has also changed the name of the property from Wainaleka to Korokayiu to reflect JOGMEC’s interest in the property.

“We welcome a partnership with JOGMEC to develop our Wainaleka high-grade VMS discovery. We’re especially pleased that JOGMEC is proposing an aggressive initial exploration program culminating in diamond drilling during this year’s field season. JOGMEC is a well-established CDN$11 billion dollar Japanese governmental entity mandated to ensure steady, cost-effective supplies of metals for their country’s industries. Wainaleka is one of Thunderstruck’s four Fijian projects, and we continue to advance these highly prospective assets with the aim of securing joint venture partners for our Rama copper/gold porphyry and Nakoro VMS, while advancing our Liwa gold project into a drill program,” said Thunderstruck President and CEO Bryce Bradley.

Historical drilling on the property by Anglo totaled 1,763 meters. Results showed that the main mineralized zone is open at both ends and at depth. Drilling intersected high-grade values including 6.2 meters grading 12.0 percent zinc, 1.8 percent copper, and 25 g/t silver, 10 meters grading 5.5 percent zinc, 2.3 percent copper, and 47 g/t silver and 15.5 meters grading 1.3 percent zinc, 1.5 percent copper, and 8.0 g/t silver.

thunderstruck korokayiu

Results from exploration work by the previous owner included:

  • 2007 surface sampling with two samples returning 19.9 percent zinc, 2.7 percent copper and 14.4 percent zinc and 7.1 percent copper.
  • 2002 trenching returned an intersection of 5.5 meters at 6.8 percent zinc, 2.6 percent copper, and 212 g/t silver and
  • near surface diamond drill intersection of 2.2 meters averaging 11.8 percent zinc, 1.9 percent copper, and 8.9 g/t silver.

Two stacked mineralized zones are apparent at Korokayiu including a high-grade central zinc zone, and an underlying copper zone. The property also hosts a historic resource that outlines 250,000 tonnes grading eight percent zinc and two percent copper.

Recent QEMSCAN mineralogical analysis by Thunderstruck on 10 samples returned an average of 26.3 percent modal sphalerite and an average of 4.2 percent chalcopyrite. Grain size observed was similar to typical VMS deposit indicating a primary grind size of 75 to 100 micron should be targeted. Sequential floatation of copper, then sphalerite into separate concentrates is the recommended processing path; with potential for dense media or gravity pre-concentration of ultra-high zinc (greater than 65 percent sphalerite) mineralization. Several reagent schemes and processing conditions can be evaluated to limit recovery of arsenic bearing minerals, and pyrite present in a minority of samples.

Nakoro Zinc-Copper Project

Nakoro is a zinc-copper VMS project and one of  Thunderstruck’s two flagship assets on the main island of Fiji, Viti Levu. Forestry roads extend across the property and the hydroelectric power station at the Monasavu Dam is only 20 kilometers northeast of Nakoro. After acquiring 100 percent ownership, Thunderstruck built a road from Nakoro village to the property to facilitate future exploration.

Previous drilling by Anglo on this massive sulphide body returned select composite mineralized intersects ranging from five to 12 percent zinc, with zones of high-grade copper at surface. Further surface exploration work will focus on expanding known zones of zinc and copper mineralization. The gold potential of the property will also be assessed, following the 2015 discovery of a siliceous rock grab sample discovered north of the main deposit that returned 3.37 g/t gold.

Nakoro map

Between 1975 and 1977, Anglo completed two diamond drill programs at Nakoro totaling 2,614 meters in 20 holes over a strike length of approximately 600 meters. Historical drill results include 12 meters grading 12.7 percent zinc, 0.3 percent copper and 56 g/t silver; 23.2 meters grading 5.1 percent zinc, 0.5 percent copper and 22 g/t silver; and 7.4 meters grading 7.2 percent zinc, 0.3 percent copper and 54 g/t silver.

Anglo’s work culminated in the release of an uncategorized historic resource prepared by Golder Associates for the Nakoro deposit of 450,000 tonnes averaging 11.6 percent zinc and 0.64 percent copper.

Small diameter “backpack” diamond drilling by the subsequent owner located zinc-copper rich zone close to the surface 120 meters north of Anglo drill hole NKD-2. Anomalous intersections included 1.3 meters grading 1.5 percent zinc, 3.3 percent copper, and 37.6 g/t silver and 1.6 meters grading 10.9 percent zinc, 3.0 percent copper, and 40.5 g/t silver.

In addition, float samples collected at that time 60 meters north of Anglo drill hole NKD-12 returned 21.1 percent copper, suggesting the property has the potential to host zones of high-copper values.

Thunderstruck conducted its initial surface exploration program at Nakoro in 2014. Fieldwork confirmed the potential for high-grade copper mineralization as well as high-grade zinc and silver. Results from the initial samples include values of 19.3 percent and 11.3 percent copper, 26 percent and 14 percent zinc and 1,026 g/t and 498 g/t silver.

Exploration at Nakoro has shown a copper zone located at surface with only a few meters of surface oxidation. The historically drilled massive zinc zone remains open along strike and at depth. Thunderstruck has recently completed a preliminary 3D geological model based on historic Anglo diamond drilling and a surface geochemical results compilation. Future plans at Nakoro will include twinning of select diamond drill holes as a confirmation of historic results, and to provide fresh material for metallurgical test-work program as a precursor towards completion of a maiden mineral resource estimate.

Rama Creek Copper-Gold Project

The Rama Creek copper-gold porphyry prospect, similar geologically to the adjacent giant Namosi porphyry copper-gold deposit, is located about five kilometers northwest of the Liwa Creek project. Thunderstruck Resources’ exploration program is focusing on the surrounding area of 14 square kilometers of anomalous gold values derived from stream sediment sampling in the 1990s. The area is highly prospective for gold and silver as such copper-gold porphyries typically have gold vein systems around them.

The stream sediment samples collected in 2017 confirmed the historic copper-gold geochemical anomaly and outlined new gold-silver anomalies in the northern segment of the property.

Anglo previously drilled only four wide-spaced holes with the central hole DDH 1 intersecting stockwork porphyry mineralization over 244 meters grading 0.22 percent copper and 0.16 g/t gold, including 72 meters at 0.38 percent copper and 0.29 g/t gold. High-grade silver assays were reported in samples from the periphery.

The field work completed in 2018 confirmed a large copper-gold porphyry system and helped to identify a broad gold mineralized zone on the property. The gold target, named Senikura West, saw trench sampling which returned values of 0.96 g/t gold over 11.1 meters. This was within a broader anomalous gold zone with an average 0.55 g/t gold over 38 meters. Further exploration work significantly increased the size of the Senikura gold zone.

“The footprint of our porphyry target has effectively doubled to approximately 1.5 km in diameter,” said Bradley. “The results of the current program strongly suggest that the Senikura gold zone, which was previously interpreted as a separate and distinct gold target south of the porphyry system, is actually part of one large and well-mineralized hydrothermal system. This is a game changer as it demonstrates that Rama has potential to be a major copper-gold system.”

Thunderstruck has completed an IP geophysical survey on the property, with results expected Q2 2019.

Liwa Creek Gold Project

The Liwa Creek gold project is a prospective high-grade gold property on the main island of Fiji, near the company’s Nakoro and Korokayiu zinc-copper VMS projects. This high-priority area contains classic epithermal, high-grade gold veins, breccia bodies and silicification zones. Other than regional sampling, minor trenching and grab sampling, little exploration had been completed prior to Thunderstruck’s exploration program.

thunderstruck liwa creek

In November and December 2017, Thunderstruck completed their first exploration program on the Liwa Creek and Rama Creek properties. On Liwa Creek, the program included field work and 530 meters of hand trenching in four separate areas on the prospect. It also included 123 prospecting rock grab samples, 110 ridge-and-spur auger soil samples and 47 BLEG stream sediment samples. Samples from the program returned results of up to 36 g/t and 31.8 g/t gold, including 12.5 percent and 6.8 percent lead in Jensen’s showing.

On the Liwa Ridge showing, the company excavated two trenches, Liwa North and Liwa South. Results from the Liwa South trench included 1.2 g/t gold over 26.5 meters including 3.6 g/t gold over 4.2 meters, within a broader anomalous zone with average grades of 0.61 g/t gold over 71 meters. In the Liwa North trench, the results were of 0.30 g/t gold over 31 meters within a broader anomalous gold zone with average grades of 0.24 g/t gold over 67 meters.

As part of this work, Thunderstruck identified a three-kilometer by three-kilometer gold mineralization zone. The samples from outcrops and trenches at both the Jensen’s and Liwa Ridge showings show the potential for the system to host favorable grades. Meanwhile, the soil and BLEG samples at other prospects show the presence of gold over a large area, suggesting the presence of a large mineralizing system comparable in scale to other large gold-bearing systems in the Pacific Rim of Fire.

Historical data at Liwa Creek includes:

  • assays of 8.4 g/t gold and 93 g/t silver from a siliceous, pyritic rock sample taken by Amoco Minerals Fiji Ltd. in the 1970s;
  • soil samples assaying up to 9.6 g/t gold; chip sampling from trenches showing 15 meters of 1.9 g/t gold; and 5.5 meters of 2.01 g/t gold from soil sampling and trenching conducted in the 1980s by Geopacific Limited; and
  • a chip sample assaying 5.7 g/t gold over seven meters has shown the potential for a regional target area.

“Multiple examples of significant gold mineralization, as well as extensive anomalies, have now been uncovered across the expanse of our property,” Bradley commented. “In particular, these results show that our Liwa and Jensen’s discoveries are shaping up to be intriguing gold targets.“

Thunderstruck has recently completed a 5km Induced Polarization geophysical survey, with results expected Q2 2019.
