Manuka Resources Limited ASX: MKR / NZX: MKR
Introduction
Manuka Resources Limited is an Australian precious-metals producer and development company with three major assets: the Wonawinta Silver Mine, the Mt Boppy Gold Project, both located in the Cobar Basin of New South Wales, and the much larger Taranaki VTM iron-sands project offshore New Zealand. The Australian assets are 100 percent owned and share the existing Wonawinta processing infrastructure, while Taranaki is held through Manuka’s wholly owned subsidiary Trans-Tasman Resources Limited.
The most important change in the Manuka story is that it has moved from planning a production restart to actually beginning the restart. On 21 August 2026, Manuka announced that gold production had recommenced at the Wonawinta processing facility using ore transported from Mt Boppy. Nearly 60,000 tonnes of Mt Boppy material had been stockpiled following a five-month refurbishment and recommissioning program. Manuka is now ramping gold processing while completing the remaining plant upgrades required for silver production, which is targeted for Q4 2026.
The near-term investment case is therefore the Cobar Basin. Manuka owns an existing approximately 1Mtpa processing plant, permitted open-pit silver and gold assets, camps and infrastructure, and has published a 10-year production strategy targeting approximately 19Moz of silver and 46koz of gold. The January 2026 updated production plan showed restart capital of approximately A$26.6M and, under a very high silver-price assumption of around A$135.50/oz, an NPV8 of approximately A$805M and average annual EBITDA of around A$127M. These numbers demonstrate strong commodity-price leverage but must not be interpreted as a conservative base case because the underlying silver-price assumption was exceptionally high.
The second part of the story is Taranaki. This project is enormous on paper, with a 3.2Bt VTM resource and a 2025 PFS showing post-tax NPV10 of US$1.26B. However, the regulatory situation has materially deteriorated. The New Zealand Fast-track expert panel proposed declining the required marine consent on 4 February 2026, and Trans-Tasman Resources subsequently withdrew the Fast-track application on 19 February 2026. Therefore, Taranaki should currently be treated as long-term speculative optionality rather than included at full PFS value in the base investment case.
The bull case for Manuka is straightforward: successfully ramp gold, restart silver production, demonstrate that Wonawinta can operate at commercial throughput and recoveries, generate cash flow, reduce debt, and eventually unlock additional value from its much larger resource inventory.
The main risks are also clear: execution, silver recovery, debt, dilution, and the uncertain regulatory future of Taranaki.
Projects / Location / MRE / Grades
Project 1: Wonawinta Silver Mine, New South Wales
Flagship Near-Term Production Asset
Wonawinta is Manuka’s flagship silver asset and the centre of its Cobar Basin production strategy. It is located approximately 85km south of Cobar in New South Wales and is 100 percent owned by Manuka.
The major advantage is infrastructure. Wonawinta already contains a conventional CIL processing facility with approximately 1Mtpa capacity, mine camp, power and associated site infrastructure. This substantially reduces the capital intensity compared with building a new silver mine and processing plant from scratch.
Wonawinta has previously produced silver under Manuka ownership, which is important because the company is not commissioning an entirely new flowsheet. The current restart nevertheless includes significant modifications, particularly a new crushing arrangement and front-end deslime/dewatering circuit intended to improve throughput and silver leach performance.
Wonawinta Mineral Resource Estimate
The broader Wonawinta Mineral Resource remains:
| Resource Category | Tonnes | Silver Grade | Contained Silver | Lead Grade | Contained Lead |
| Measured | 1.1Mt | 47.3 g/t Ag | 1.65Moz Ag | 0.69% | 7.5kt |
| Indicated | 12.3Mt | 45.5 g/t Ag | 18.04Moz Ag | 0.83% | 102.8kt |
| Inferred | 24.9Mt | 39.0 g/t Ag | 31.25Moz Ag | 0.39% | 96.9kt |
| Total | 38.3Mt | 41.3 g/t Ag | 50.94Moz Ag | 0.54% | 207.2kt |
An additional historical stockpile was reported at approximately 0.515Mt grading around 70 g/t silver for approximately 1.16Moz silver. The main 38.3Mt resource was originally defined in 2021 but continues to be referenced by Manuka as the broader Wonawinta resource.
This resource is important because the current reserve represents only a portion of the overall 51Moz silver inventory. A large amount of Inferred material remains outside the current reserve, creating resource-conversion and mine-life-extension optionality.
Updated Wonawinta Ore Reserve
In July 2026, Manuka announced a 28 percent increase in the Wonawinta Ore Reserve.
The updated Probable Ore Reserve is approximately:
| Ore Reserve | Tonnes | Grade | Contained Silver |
| Probable Reserve | 7.9Mt | 50.4 g/t Ag | 12.8Moz Ag |
The updated reserve is based on open-pit mining and includes material associated with existing and planned pits. Importantly, only higher-confidence resource material was given economic value in the reserve optimisation, while Inferred Resources were effectively excluded. This means conversion of additional Inferred resources could provide future mine-life upside.
Cobar Basin Production Plan
The January 2026 updated production strategy outlined:
| Metric | Published Plan |
| Mine life | ~10 years |
| Total production target | ~10.9Mt |
| Silver production | ~19Moz |
| Gold production | ~46koz |
| Processing infrastructure | Existing ~1Mtpa Wonawinta plant |
| Restart capital | ~A$26.6M |
| High-price-case average EBITDA | ~A$127M/year |
| High-price-case NPV8 | ~A$805M |
| High-price-case IRR | ~1,092% |
| Silver assumption | ~A$135.50/oz |
The economics are extremely sensitive to silver prices. Therefore, the A$805M NPV should be considered a high-price sensitivity case rather than a conservative valuation anchor.
Wonawinta Cost Structure
Earlier Manuka modelling used an AISC of around A$30.1/oz silver including gold credits under lower price assumptions. The February 2026 presentation showed a higher cost case with approximately A$34.40/oz C1 cost and around A$42.40/oz AISC, depending on the particular production plan and commodity-price assumptions used.
The important point is that these are study estimates, not yet demonstrated 2026 operating costs.
The real test will be actual tonnes processed, silver recoveries, throughput, mining costs, haulage, consumables, labour, maintenance and realised AISC after the plant reaches steady-state production.
Wonawinta Grade Feel
Wonawinta is not an ultra-high-grade underground silver system. The reserve grade of approximately 50.4 g/t Ag is moderate.
What makes the asset interesting is not grade alone. It is the combination of:
- A large approximately 51Moz silver resource.
- A 12.8Moz current reserve.
- Shallow open-pit material.
- Existing processing infrastructure.
- Existing mining approvals.
- A strategic location in the Cobar Basin.
- Potential gold credits from Mt Boppy.
- Potential resource conversion beyond the current reserve.
Overall, Wonawinta is more of an infrastructure + scale + silver leverage story than a pure high-grade silver story.
Project 2: Mt Boppy Gold Project, New South Wales
High-Grade Gold Feed and Exploration Optionality
Mt Boppy is located approximately 150km by road from the Wonawinta processing facility and is 100 percent owned by Manuka.
Historically, Mt Boppy was one of New South Wales’ highest-grade gold mines and produced approximately 500,000oz of gold at around 15 g/t gold historically. The modern project consists of the existing open pit, stockpiles, waste/rock dumps, tailings and surrounding exploration ground.
The key strategic advantage is that Manuka does not need to construct a separate processing plant at Mt Boppy. Gold-bearing material can be crushed, transported to Wonawinta and processed through the existing CIL facility.
Mt Boppy Current Resource Position
Recent company presentations describe approximately 2.6Mt of total mineralised material/resources at around 1.32 g/t gold, including higher-grade in-ground material and lower-grade rock dumps, tailings and stockpiles.
More importantly, Manuka has established a Probable Ore Reserve for a Mt Boppy open-pit cutback:
| Ore Reserve | Tonnes | Gold Grade | Contained Gold |
| Probable Reserve | 290kt | 4.2 g/t Au | ~39,000oz Au |
The project study estimated a pre-tax NPV8 of approximately A$43.2M and IRR of approximately 64 percent at the study assumptions.
A 4.2 g/t open-pit reserve is very attractive grade-wise. This is one of the strongest parts of the Manuka asset base.
2026 Gold Restart
Manuka began processing Mt Boppy gold ore through Wonawinta on 21 August 2026.
Prior to commencement, almost 60,000 tonnes of Mt Boppy ore had been transported and stockpiled at Wonawinta. The initial commissioning material is significantly lower grade than the 4.2 g/t future open-pit reserve, with the stockpiled commissioning feed reportedly around the 1.1 g/t area.
This distinction matters.
The early gold production phase is primarily designed to bring the plant online and generate initial cash flow. The higher-grade Mt Boppy open-pit reserve provides potential future production after the stockpile phase.
Pipeline Ridge and Mt Boppy Exploration Upside
Manuka continues to explore around Mt Boppy.
Initial deep drilling south of the Mt Boppy system did not intersect significant high-grade gold zones, which is a negative result investors should acknowledge rather than ignore.
However, resource-definition drilling commenced at Pipeline Ridge on 24 April 2026, targeting shallow gold mineralisation potentially suitable for future open-pit development.
Pipeline Ridge remains exploration upside and should not currently be valued as a defined mining asset.
Mt Boppy Grade Feel
Mt Boppy’s 4.2 g/t gold Probable Reserve is high grade for an open-pit gold project.
This is one of Manuka’s strongest characteristics.
If Manuka successfully transitions from lower-grade commissioning stockpiles into the higher-grade Mt Boppy reserve, the gold contribution could become more meaningful.
Project 3: Taranaki VTM Project, New Zealand
Huge Long-Term Optionality but Major Regulatory Risk
Taranaki is potentially Manuka’s largest asset by economic scale.
The project is located offshore in the South Taranaki Bight, New Zealand and is owned 100 percent through Manuka’s wholly owned subsidiary Trans-Tasman Resources Limited.
The project contains vanadiferous titanomagnetite iron sands containing iron, vanadium and titanium.
Taranaki Mineral Resource Estimate
| Resource Category | Tonnes | Fe₂O₃ | TiO₂ | V₂O₅ |
| Indicated | ~2.1Bt | 10.45% | 1.06% | 0.05% |
| Inferred | ~1.1Bt | 9.64% | 0.99% | 0.04% |
| Total | 3.2Bt | 10.17% | 1.03% | 0.05% |
The resource contains approximately 1.6Mt V₂O₅.
Approximately two-thirds of the resource is already in the Indicated category. TTR holds Mining Permit MMP55581, covering approximately 1.88Bt of the resource, as well as adjoining exploration tenure.
Taranaki 2025 PFS Economics
The March 2025 Pre-Feasibility Study outlined:
| PFS Metric | Value |
| Initial mine life | 20 years |
| Concentrate production | ~4.9–5.0Mtpa |
| Concentrate grade | 56–57% Fe |
| Vanadium grade | ~0.5% V₂O₅ |
| Titanium grade | ~8.5% TiO₂ |
| Initial capex | US$602M |
| C1 operating cost | US$27.20/t concentrate |
| Average annual EBITDA | US$312M |
| Post-tax NPV10 | US$1.26B |
| IRR | 39% |
The PFS used assumptions including a flat benchmark iron concentrate price of US$90/t CFR China, with a 13.7 percent discount, vanadium pricing of US$5.45/lb V₂O₅ with recovery/payability adjustments, and approximately US$10/t freight.
On paper, these are exceptional economics.
But the economics are not the problem.
Permitting is the problem.
Critical Taranaki Regulatory Update
Older Manuka presentations described Taranaki as moving through New Zealand’s Fast-track approvals process.On 4 February 2026, the Fast-track expert panel released a draft decision proposing to decline the marine consent. On 19 February 2026, Trans-Tasman Resources formally withdrew the Fast-track application.
Therefore:
Taranaki currently has no successful Fast-track approval.
The project retains its mineral resource, mining permit and technical work, but the environmental/marine approval pathway required to develop the project remains unresolved.
Share Structure / Ownership / Insiders
Capital Structure
Manuka has experienced substantial equity issuance and option exercises over the past several years.
The latest confirmed ordinary share count after the May/June 2026 exercises is:
| Capital Structure Metric | Value |
| Ordinary shares outstanding | 1,586,817,694 |
| Recent share price | ~A$0.096 |
| Basic market capitalization | ~A$152M |
| Cash — 30 June 2026 | A$7.8M |
| Total borrowings — 30 June 2026 | A$52.5M |
| Approx. net debt | A$44.7M |
| Nebari senior secured facility | US$30M |
| Recent trading liquidity | ~10M shares/day range during August |
The latest ordinary share count is confirmed by the June 2026 securities filings. Manuka has subsequently lodged a 25 August cessation-of-securities notice, but the ordinary share count remained approximately 1.59B.
At approximately A$0.096 per share, Manuka’s basic market capitalization is approximately A$152M.
Unquoted Securities
As of the 30 June 2026 securities register, major potentially dilutive instruments included approximately:
| Instrument | Quantity |
| Options expiring Dec. 2027 @ A$0.15 | 42.5M |
| Warrants | 58.92M |
| Options expiring Aug. 2028 @ A$0.10 | 36.0M |
| Options expiring Apr. 2027 @ A$0.107 | 5.0M |
| New Nebari warrants expiring June 2030 | 8.23M |
| Convertible notes | 3.65M notes |
The 8.23M new Nebari warrants have an exercise price of A$0.1357 and expire in June 2030.
Adding the known one-for-one options and warrants to the ordinary shares gives an illustrative diluted share base of approximately 1.74B shares before considering the precise conversion terms of the convertible notes.
An August 25 cessation notice subsequently changed part of the unquoted register, so approximately 1.74B should be treated as a conservative working diluted-share assumption rather than an exact live fully diluted figure.
Ownership / Insiders
Current disclosed major holdings include approximately:
| Holder | Shares | Approx. Ownership |
| Antanas Guoga | 72.40M | 4.56% |
| Alan Eggers | 61.38M | 3.87% |
| John Seton | 51.16M | 3.22% |
| Dennis Karp | 47.65M | 3.00% |
| Soothgrove Pty Ltd | 35.98M | 2.27% |
The three current directors Dennis Karp, Alan Eggers and John Seton collectively control approximately 160.2M ordinary shares, equivalent to roughly 10.1 percent of the current ordinary share base.
That is meaningful alignment, but it is not exceptionally high insider ownership.
Dennis Karp’s July 2026 reduction needs context. The reported approximately 9.06M-share change was described as an in-specie distribution by ResCap Investments, rather than simply an ordinary bearish on-market disposal.
Management also holds options, which increases economic alignment, although options should not be counted as current share ownership.

Risks / Catalysts / Timeline
Key Risks
| Key Risk | Why It Matters |
| Production Ramp-Up Risk | Gold processing restarted only in August 2026. Manuka still needs to prove sustained throughput, recoveries, plant availability and operating costs. |
| Silver Restart Risk | Silver production is targeted for Q4 2026 but has not yet restarted. Installation and commissioning of the deslime system remain critical. |
| Metallurgical Risk | Wonawinta contains clay/slime material. The new deslime and dewatering circuit is intended to address historic processing constraints. Actual results still need to be demonstrated. |
| Grade Reconciliation Risk | Mt Boppy commissioning stockpile grades are lower than the 4.2 g/t open-pit reserve. Future mining needs to prove reserve grades in real production. |
| Resource Conversion Risk | A substantial portion of Wonawinta’s 51Moz resource remains Inferred and outside the reserve. Conversion is not guaranteed. |
| Debt Risk | At 30 June 2026, Manuka had approximately A$52.5M borrowings against only A$7.8M cash. The restart therefore needs to generate cash relatively quickly. |
| Nebari Financing Risk | The US$30M senior secured facility has security over company assets and creates interest and repayment obligations. Principal repayments begin after an initial deferral period. |
| Dilution Risk | Approximately 1.59B ordinary shares are already outstanding with additional options and warrants. |
| Commodity Price Risk | Manuka is highly leveraged to silver and gold prices. Project NPV changes dramatically as silver prices move. |
| Taranaki Approval Risk | The Fast-track panel proposed declining marine consent and TTR withdrew the application. There is currently no defined successful approval pathway. |
| Taranaki Financing Risk | The PFS requires approximately US$602M initial capex, many times Manuka’s current market capitalization. A strategic partner, major project financing or other structure would likely be necessary. |
| Environmental / Social Risk | Offshore seabed mining is environmentally and politically sensitive in New Zealand. This is likely to remain a major challenge. |
| Haulage Risk | Mt Boppy ore needs to be transported approximately 150km to Wonawinta, creating additional logistics and cost exposure. |
| Exploration Risk | Recent deep Mt Boppy drilling failed to intersect significant high-grade zones. Pipeline Ridge and regional exploration remain unproven. |
Catalysts
| Timeline | Key Milestone |
| August–September 2026 | Ramp-up of gold processing at Wonawinta |

Expected Timeline to Full Production
| Year / Period | Focus | What It Means |
| August 2026 | Gold restart | Already achieved. Mt Boppy gold-bearing material began processing through Wonawinta on 21 August. |
| Q3–Q4 2026 | Plant ramp-up | Manuka needs to demonstrate consistent gold processing while completing silver-specific plant upgrades. |
| Q4 2026 | Silver restart target | This is the next major milestone. Successful silver commissioning would materially de-risk the company. |
| 2027 | Cobar steady-state phase | If commissioning succeeds, 2027 should be the first year investors can evaluate Manuka primarily on production, recoveries, costs and cash flow rather than restart promises. |
| 2027 onward | Resource conversion / optimisation | Wonawinta’s larger 51Moz resource provides potential mine-life-extension opportunities beyond the existing 12.8Moz reserve. |
| 2028 onward | Higher-grade Mt Boppy contribution | The Mt Boppy open-pit reserve provides potential future higher-grade gold feed under the broader mine plan. |
| Long Term | Taranaki | No reliable production date should currently be assigned. The approval pathway must first be rebuilt. |
Valuation
Important Valuation Note
The near-term Cobar Basin operation is primarily a silver project with gold credits and additional Mt Boppy gold production, while Taranaki is a completely separate long-term iron-vanadium-titanium development project.
Therefore, the most sensible valuation framework is:
- Value the Cobar Basin silver-gold operation as the core asset.
- Adjust heavily for restart and execution risk.
- Deduct net debt.
- Add conservative optionality for resources outside the current mine plan.
- Give Taranaki only a deeply discounted optionality value until its regulatory pathway becomes credible again.
Published Cobar Valuation Reference
A lower-price company study used approximately:
- A$50/oz silver
- Approximately A$5,000/oz gold
- Wonawinta NPV8 of approximately A$101M
- Mt Boppy open-pit NPV8 of approximately A$43.2M
This gives approximately A$144M of combined project NPV before corporate debt and other adjustments.
At the other extreme, Manuka’s January 2026 updated high-price production case showed approximately:
- A$135.50/oz silver.
- Approximately 19Moz silver production.
- Approximately 46koz gold production.
- Average EBITDA around A$127M.
- NPV8 around A$805M.
This gives us a very wide valuation range.
Silver Price Sensitivity
One of the most useful disclosures from Manuka is that at the A$50/oz silver base case, the company estimated that every 10 percent increase in silver price increased project NPV by approximately A$43M.
Using that sensitivity mechanically for illustration:
| Silver Price | Increase vs A$50 | Illustrative Wonawinta NPV |
| A$50/oz | Base | A$101M |
| A$75/oz | +50% | ~A$316M |
| A$100/oz | +100% | ~A$531M |
| A$125/oz | +150% | ~A$746M |
| A$135.50/oz | +171% | ~A$836M |
This is not an official company forecast. It simply extrapolates the company’s disclosed A$43M-per-10-percent sensitivity.
Interestingly, the extrapolated result at approximately A$135.50 silver is reasonably close to the later published A$805M high-price NPV, which confirms how powerful the silver-price leverage is.
Optionality Value Assumptions
Assets outside the core current mine plan do not have sufficiently reliable near-term cash-flow forecasts to justify full NPV valuation.
Therefore, I would use deliberately conservative optionality values.
| Optionality Asset | Conservative | Base | Aggressive |
| Wonawinta resource outside current reserve | A$10M | A$25M | A$50M |
| Mt Boppy / Pipeline Ridge exploration | A$5M | A$15M | A$30M |
| Taranaki VTM regulatory optionality | A$0M | A$50M | A$150M |
| Total Optionality | A$15M | A$90M | A$230M |
The Taranaki values are intentionally tiny compared with its US$1.26B PFS NPV.
That is deliberate.
Until Manuka establishes a credible consenting pathway, applying anything close to full PFS value would be too aggressive.
Simplified Risked NAV Valuation
For this model:
- High-price Cobar NPV reference: A$805M
- Approximate net debt: A$44.7M
- Working diluted share count: ~1.737B
- Taranaki remains heavily discounted.
- Risk factors reflect Manuka’s current ramp-up stage.
| Scenario | Cobar NPV Recognition | Core Value | Optionality | Less Net Debt | Implied Equity Value | Approx. Value / Diluted Share |
| Conservative | 25% | A$201M | A$15M | A$44.7M | A$172M | ~A$0.10 |
| Base | 40% | A$322M | A$90M | A$44.7M | A$367M | ~A$0.21 |
| Aggressive | 60% | A$483M | A$230M | A$44.7M | A$668M | ~A$0.38 |
| High-Price / De-Risked | 100% | A$805M | A$230M | A$44.7M | A$990M | ~A$0.57 |
These are scenario values, not formal price targets.

RT Rating, Commentary
Manuka Resources is on our watchlist.
We would rate this as 4 out of 5 stars.
Manuka ticks a surprising number of important boxes.
The strongest positive is that this is no longer simply a junior company promising production sometime in the future. Gold processing has actually restarted at Wonawinta, and the next major milestone is silver production targeted for Q4 2026.
The second major positive is infrastructure. Manuka already owns the Wonawinta processing plant, mine camp and operating infrastructure. This is extremely important because it allows the company to restart the Cobar Basin operation with tens of millions of dollars rather than having to finance a several-hundred-million-dollar greenfield build.
The third positive is the asset base.
Wonawinta contains approximately 51Moz silver, with a current Probable Reserve of approximately 12.8Moz at 50.4 g/t silver.
Mt Boppy provides approximately 39,000oz of Probable Reserves at 4.2 g/t gold, which is very attractive grade for open-pit material.
And beyond those assets sits Taranaki, with 3.2Bt of VTM resource and a PFS showing US$1.26B NPV10.
The management team is also above average. Alan Eggers’ history with Summit Resources and its eventual A$1.2B acquisition by Paladin provides evidence of previous value creation. The operating team includes people with Newcrest, Tomingley, Telfer, Northparkes, Trafigura and Randgold backgrounds. That is important because Manuka’s next phase is about execution, not exploration storytelling.
There are, however, several reasons why this is not a 5-star stock yet.
The debt.
Approximately A$52.5M of borrowings against A$7.8M cash means the company needs the production restart to work. Strong operating cash flow could quickly improve the balance sheet, but production delays or poor recoveries could create financial pressure.
The next risk is operational execution.
Starting the plant is only step one.
The company now needs to prove:
- Stable throughput.
- Gold recoveries.
- Silver recoveries.
- Successful operation of the deslime circuit.
- Mining productivity.
- Grade reconciliation.
- Operating costs.
- AISC.
- Debt repayment capability.
If those numbers are good, the market could begin valuing Manuka as an actual producer rather than a speculative restart company.
Another issue is Taranaki. On paper, Taranaki is potentially transformational.
In reality, the Fast-track application was withdrawn after the expert panel proposed declining the required marine consent. Until Manuka produces a credible new consenting strategy, we would assign only a small fraction of the PFS value to Taranaki.
The interesting part is that the investment case does not necessarily require Taranaki to work.

At RockeTeller, we do not just chase stories. We hunt for rare mining stocks with the right mix of criteria. Every company is tested through our specific checklist before it earns a place on our watchlist.
We ask the hard questions that matter most: Is this a stock we would actually back, what is the realistic target price, and how strong is the risk-reward?
Our watchlist is reserved for high-quality setups with real multibagger potential, not hype. If you want serious deep-dive research with conviction, subscribe to RockeTeller.com.
