Investor Insight
Manuka Resources’ unique value proposition is focused on its three fully licenced projects, which include two precious metals assets in one of Australia’s most prolific regions for base and precious metals, and a company-making iron sands (vanadium and titanium co-products) project in New Zealand’s exclusive economic zone (EEZ) off the Taranaki bight. Manuka Resources is well-placed to deliver significant shareholder value, driven by a phased strategy that includes a clear pathway to near-term precious metals production.
Strategy Overview
Manuka Resources (ASX:MKR) is focused on bringing its precious metals assets in the Cobar Basin into production, as well as progressing its New Zealand domiciled Taranaki VTM iron sands project.
The company previously revealed a phased strategy focused on delivering maximum value to its shareholders. The first phase focused on bringing back the Mt Boppy gold mine into production and it released an optimised production plan for the mine restart. At the time, the company believed silver production would follow gold but noted it was flexible in this regard. In any event and simultaneous to this, will be the ongoing development of the Taranaki vanadium titano-magnetite (VTM) project.
The Cobar Basin located in the central-west of New South Wales, is one of the richest mining provinces in Australia, home to some of Australia’s largest mining companies and explorers.
The Mt Boppy gold mine was historically one of the richest in NSW, Australia and produced ~500,000 oz gold at an average grade of 15 grams per ton (g/t) gold. Accordingly, the company is very excited about its exploration potential.

The initial five-year mine plan is largely focused on the screening and processing of gold-bearing waste material above ground on the Mt Boppy mine site. The company had been processing these wastes from June 2023 to December 2023 at its Wonawinta plant and now will look to optimize the process.
The Wonawinta silver project will be the largest primary silver producer in Australia and expected to be back in silver production within 12 months. Manuka has released a maiden ore reserve (under its ownership) of 4.8Mt1 at 53.8g/t silver containing 8.4Moz of silver comprising proven ore reserves of 0.8Mt at 50.8g/t silver; and probable ore reserves of 4.1Mt at 54.3g/t silver. Ore Reserve is based solely on shallow (<40m deep) oxide material.

The gold and silver market appears to be in an upward trend, with prices for both precious metals hitting their all-time highs recently, in Australian dollar terms for silver, which bodes very positively for MKR.
Company Highlights
- Manuka Resources is an ASX-listed mining company focused on producing gold and silver from its two 100 percent owned fully permitted projects (one gold and one silver) in the Cobar Basin in New South Wales, Australia.
- In addition, MKR’s wholly owned subsidiary Trans-Tasman Resources Limited (“TTR”) is the owner of the Taranaki VTM (vanadiferous titanomagnetite) iron sands project, located in the New Zealand EEZ, off the south-west coast of the north island.
- Manuka released the details of the Taranaki VTM project’s pre-feasibility study (PFS) on 26 March 2025, which highlights the extremely robust economics of the project with an NPV10 of US$1.2B and IRR 39 percent
- TTR will also be lodging its application under New Zealand’s Fast Track Approvals Act for the Taranaki VTM project imminently. (The project was included in Schedule 2 of the Act). Successful conclusion of review under the Fast Track pathway will result in final regulatory approvals (marine discharge consent) being granted, completing the full suite of consents to operate the project for 20 years.
- The Company’s primary focus for its precious metals assets is on bringing both the fully permitted Wonawinta silver project and the Mt Boppy gold mine back into production during 2025. The Wonawinta processing plant (primarily constructed for silver production in 2012 with production capacity of 850,000-1 million tpa) has been recently used for both gold and silver processing and is on active care and maintenance for rapid restart..
- The Wonawinta silver project was previously the largest primary producer of silver in Australia, and Manuka expects this to again be the case once production restarts.
- While the substantially higher gold prices have been securing headlines over the past six months, it is worth noting that the silver price is also trading at an all time high which makes restarting the project very attractive (the all time high for silver is against the Australian dollar, currently silver is around AU$54/oz silver).
- Manuka released its maiden silver reserve in October 2024 making it the only production ready silver reserve on a project based in Australia.
- Elevated gold and silver prices should materially benefit Manuka Resources, resulting in strong profitability and cash flows once its projects move into production.
Key Projects
Mt Boppy Gold Project
The Mt Boppy gold project comprises three mining leases, four gold leases and one exploration license, spanning an area of more than 210 sq km in the prolific Cobar Basin in New South Wales, Australia. The project was acquired by Manuka in 2019 and has a current mineral resource of 4.3 Mt at 1.19 g/t gold. This includes a combination of oxidized and transitional/fresh mineralization in the ground, as well as mineralized rock dumps and tailings.
Historically, Manuka Resources has processed its stockpiles and gold mineralized waste products through its Wonawinta processing plant. However, inefficiencies associated with trucking and processing ore at the distant Wonawinta plant has led the company to revise its strategy. It is now looking to construct a processing plant at Mt Boppy so that ore from the mine can be processed on-site. Mt Boppy has excellent infrastructure including a 48-person mine camp and is fully permitted for the proposed processing plant and on-site production.
The updated mineral resource comprises 4.28 Mt at 1.19 g/t gold for 163 koz of contained gold, of which 82 percent is in the measured and indicated categories.
An on-site plant will offer significant cost savings and improve the project economics.
Manuka Resources anticipates Mt Boppy to deliver total EBITDA of >AU$90 million and cash flow of >AU$80 million over a five-year mine life.
Wonawinta Silver Mine Project
The Wonawinta plant
The Wonawinta project is fully permitted with all the necessary infrastructure, including an 850,000 to 1 million tpa processing plant. The plant has been used for processing ore from Mt Boppy. The Wonawinta silver mine is currently under care and maintenance. The company is considering the possibility of resuming operations at Wonawinta, leveraging the improved silver price environment. Manuka has released a maiden ore reserve (under its ownership):
- Ore Reserve of 4.8 Mt at 53.8 g/t silver containing 8.4 Moz of silver comprising:
- Proved Ore Reserves of 0.8 Mt at 50.8 g/t silver; and
- Probable Ore Reserves of 4.1 Mt at 54.3 g/t Ag.
The maiden silver ore reserve and the preparation of an implementation plan for Wonawinta support the potential restart of silver mining and processing operations in the near
future. The company is reviewing its silver restart plans in light of the current price increases and expects to announce a decision before the end of May 2025.
Taranaki VTM Project
The Taranaki VTM project is located within New Zealand's exclusive economic zone, approximately 22 to 36 kilometres offshore, outside the 12 nautical mile boundary from the coastline. The project boasts a JORC resource of 3.2 billion tons at 10.17 percent iron oxide, 1.03 percent titanium dioxide and 0.05 percent vanadium oxide. It holds a mining license allowing initial extraction of 50 million tons annually, resulting in 5 million tons of VTM concentrate per year for 20 years (concentrate grade of 56 to 57 percent iron, 8.5 percent titanium dioxide and 0.5 percent vanadium pentoxide). At this extraction rate, the JORC resource provides approximately 60 years of potential mining inventory.
The project was included in the New Zealand government's Schedule 2 of the Fast Track Approvals Act 2024. The next step for Manuka was to complete pre-feasibility study (“PFS”) on the project. This was released to the market on 26 March 2025 and presents an extremely robust economic outlook for the project as can be seen below.
