Investigator Silver Limited ASX: IVR
Introduction
Investigator Silver Limited is an Australian silver development company focused on advancing the 100 percent owned Paris Silver Project in South Australia. The company was formerly known as Investigator Resources, but the story has now clearly shifted from early-stage exploration into mine development, execution readiness, financing, permitting, and ultimately first silver production.
The bull case is simple: Investigator controls what the company positions as Australia’s only pure-play, near-term silver mine development opportunity. Paris is not a remote, complex, multi-metal science project. It is designed as a shallow open-pit silver operation using contract mining, conventional whole-ore cyanide leach processing, and Merrill–Crowe doré recovery. The 2026 DFS outlines a 1.5Mtpa operation, approximately 11-year mine life, 30Moz of silver doré production, A$39.70/oz AISC, and strong economics at higher silver prices.
The most important attraction is leverage. In the DFS spot case using US$80/oz silver and AUD/USD 0.69, Paris delivers pre-tax NPV8 of A$1.154B, pre-tax IRR of 93 percent, payback of 11 months from first production, and A$1.866B of pre-tax net project cash flow. At the consensus case of US$60.18/oz silver, the project still shows pre-tax NPV8 of A$618M, pre-tax IRR of 61 percent, payback of 13 months, and A$1.038B of pre-tax net project cash flow.
The key risk is also clear: Investigator still needs to move from DFS into construction decision, final financing, permits, early works, construction, commissioning, and actual operation. The project looks financeable on paper, but the market will still demand proof that the company can build it on time, on budget, and without excessive dilution.
Projects / Location / MRE / Grades
Project 1: Paris Silver Project, South Australia (Flagship Development Asset)
Paris is Investigator Silver’s flagship asset. The project is 100 percent owned and located on South Australia’s Eyre Peninsula, around 70km north of Kimba and about seven hours by road from Adelaide. The DFS describes Paris as a conventional open-pit silver project in a mature South Australian mining jurisdiction with established infrastructure and regulatory framework.
This matters because Paris is not a difficult underground vein project in a high-risk country. It is designed as a shallow open-pit mine with a simple processing route. The DFS describes the operation as contract mining, whole-ore cyanide leach, Merrill–Crowe doré recovery, and wet tailings storage.
The project also sits inside a broader 15km Paris Silver Corridor. That gives Investigator more than just a single-pit development story. The current DFS is based on Paris, but the company sees multiple near-plant targets that could potentially extend mine life or add satellite feed over time.
Paris is high grade for an open-pit primary silver project. The global JORC 2012 Mineral Resource is 24Mt at 73g/t silver and 0.41 percent lead for 57Moz silver and 99kt lead. The 2026 maiden Ore Reserve is 12Mt at 88g/t silver for 33Moz silver, all in the probable category.
This is the important part. Paris is not a huge low-grade bulk-tonnage silver project that needs a monster plant to work. It is a relatively simple, shallow, higher-grade open-pit silver development. The DFS mine plan uses 13.395Mt of ore mined and processed at an average silver grade of 91g/t, with 78 percent silver recovery and 30Moz of silver in doré produced.
The project does contain lead in the resource, but lead was not considered in the DFS economics. This makes Paris cleaner from a silver-purity perspective, but it also means the current mine plan is mainly a silver doré story rather than a silver-lead concentrate story.
The current Paris Mineral Resource Estimate is JORC 2012 compliant and was last updated in 2023.
Resource summary
The key strength is that most of the resource is already indicated. The DFS production target is also stronger than many early-stage developers because it is based on 86 percent indicated resources and only 14 percent inferred resources. During the payback period, less than 1 percent of the production target comes from inferred material, which improves lender confidence.
The 2026 DFS delivered the maiden Ore Reserve for Paris.
Reserve summary
This is a major milestone. Moving from a resource-only story to a reserve-backed DFS gives Investigator a much stronger development profile. The reserve is based on the 2023 resource and incorporates mine design, scheduling, geotechnical work, hydrogeology, dilution, mining recovery, metallurgy, processing, infrastructure, tailings, operating costs, capital costs, and economic assumptions.
The 2026 DFS is now the main valuation anchor for Investigator Silver.
Key DFS figures
The standout number is the A$260M development funding requirement. This is not tiny, but it is modest compared with the DFS value at higher silver prices. At US$80/oz silver, the NPV8-to-development funding ratio is approximately 4.4 times. At US$60.18/oz silver, the ratio is still around 2.4 times. (ASX Announcements)
The second standout is silver price sensitivity. Holding mine plan, costs, and foreign exchange constant, the company says each extra US$1/oz in silver price adds approximately A$27M to pre-tax NPV8 and A$42M to life-of-project pre-tax net cash flow. That is the main reason IVR is interesting. It is not just a development story. It is a silver-price torque story.
Paris Mineral Resource Estimate
| Category | Tonnes | Silver Grade | Lead Grade | Contained Silver | Contained Lead |
| Indicated | 17Mt | 75 g/t Ag | 0.50% Pb | 41Moz Ag | 85kt Pb |
| Inferred | 7.2Mt | 67 g/t Ag | 0.42% Pb | 16Moz Ag | 14kt Pb |
| Total | 24Mt | 73 g/t Ag | 0.41% Pb | 57Moz Ag | 99kt Pb |
The key strength is that most of the resource is already indicated. The DFS production target is based on 86 percent indicated resources and only 14 percent inferred resources. During the payback period, less than 1 percent of the production target comes from inferred material, which improves lender confidence.

| Average silver grade | 91 g/t Ag |
| Silver recovery | 78% |
| Silver dore produced | 30Moz |
| Strip ratio | 5.96:1 |
| Development funding requirement | A$260M |
| AISC | A$39.70/oz |
| Consensus silver case | US$60.18/oz |
| Spot silver case used in DFS | US$80/oz |

| Spot payback from first production | 11 months |
| Spot pre-tax net project cash flow | A$1.866B |
| Spot post-tax net project cash flow | A$1.356B |
The standout number is the A$260M development funding requirement. This is not tiny, but it is modest compared with the DFS value at higher silver prices. At US$80/oz silver, the NPV8-to-development funding ratio is approximately 4.4 times. At US$60.18/oz silver, the ratio is still around 2.4 times.
The second standout is silver price sensitivity. Holding mine plan, costs, and foreign exchange constant, each extra US$1/oz in silver price adds approximately A$27M to pre-tax NPV8 and A$42M to life-of-project pre-tax net cash flow.
Project 2: Paris Silver Corridor (Near-Plant Growth Optionality)
The Paris Silver Corridor is the second major part of the story. Paris itself is the flagship asset, but the broader corridor gives Investigator room to extend the mine life and potentially add satellite material around the planned plant and tailings facility.
The company describes Paris as sitting within a 15km mineralised corridor with multiple near-plant drill targets. The key advantage is that any satellite discovery near the proposed infrastructure could be more valuable than a standalone remote discovery because it may use the same processing plant, mine services, approvals pathway, and local infrastructure.
This is important because the current DFS mine life is attractive, but not extremely long. If Investigator can convert more resources near the pit or along the corridor, Paris could become a longer-life silver platform instead of a single open-pit development.
Project 3: Uno Morgans / Curnamona / Regional Exploration (Exploration Upside)
Investigator still has exploration upside beyond the core Paris pit. The company’s presentation highlights Paris pit expansion drilling, Paris Silver Corridor drilling, Uno Morgans hub-and-spoke drilling, and Curnamona drilling as part of the next 12 months of news flow.
This optionality matters because Paris already has a defined DFS development case. Exploration is not needed to justify the current project, but success could improve mine life, scale, and market perception.
Molyhil is no longer the key focus. Investigator has completed the divestment of the Molyhil tungsten-molybdenum project, which helps simplify the company into a cleaner silver development story.
Share Structure / Ownership / Insiders
Capital Structure
| Capital Structure Item | Value |
| Shares on issue before placement | 1.985B |
| Placement shares | 640M |
| Pro-forma shares on issue | 2.625B |
| Listed options | 463M options at A$0.042, expiring March 2028 |
| Simplified fully diluted shares | Approximately 3.088B |
| Pro-forma cash after placement | A$68M |
| Top 20 shareholders | 35% |
| Jupiter Asset Management | 14% |
| Recent share price / market cap | A$0.061-A$0.064 / about A$166M |
Share Structure Feel
The share count is high. That is the biggest negative in the capital structure. A pro-forma basic share count of 2.625B shares, plus 463M listed options, means investors must be careful with per-share valuation.
The positive side is that the company raised A$55M in March 2026, materially strengthening the balance sheet and funding execution readiness, early construction and long-lead items, drilling, permitting, and working capital. The placement proceeds should fund Investigator through to a Final Investment Decision for Paris.
Ownership / Insiders
Jupiter Asset Management is the key institutional shareholder at approximately 14 percent, while the top 20 shareholders hold approximately 35 percent. This is a positive sign for a development-stage silver company that will need continued capital-market support, although insider/director ownership does not appear extremely high based on available public ownership data.
People / Management
| Person | Role | Management Feel |
| Lachlan Wallace | Managing Director | Key executive for the next stage. Mining engineer and resource executive with South Australian mine-development experience, including leadership connected to the Kanmantoo Copper Mine. Strong fit for development, permitting, construction, lenders, contractors, and operational discipline. |
| Richard Hillis | Non-Executive Chairman | Provides governance and board-level oversight as Investigator transitions from explorer to developer. Board discipline, financing strategy, and risk management become more important from here. |
| Andrew Shearer | Non-Executive Director | Provides continuity and previously served as interim Managing Director during the leadership transition before Lachlan Wallace joined. |
| Anita Addorisio | CFO & Company Secretary | Important for project funding, equity dilution, working capital, capital costs, debt financing, and construction readiness. Investors should watch the final funding structure. |
| Jason Murray | Exploration Manager | Competent Person for exploration results. Direct involvement in Paris resource growth since 2012 and relevant for pit expansion, regional discovery, and the Paris Silver Corridor upside. |
Risks / Catalysts / Timeline
Key Risks
| Risk Category | Key Risk |
| Financing risk | Paris has a development funding requirement of A$260M. The A$55M placement helps, but full project financing is still required before construction. |
| Dilution risk | The share count is already high, and more equity may be needed. The 463M listed options could add dilution if exercised. |
| Permitting risk | Investigator still needs to complete approvals and permitting before full development can proceed. |
| Construction risk | DFS numbers are not the same as a built mine. Capital cost overruns, schedule delays, contractor issues, and commissioning problems can happen. |
| Silver price risk | Paris is highly sensitive to silver price. Weaker silver prices would reduce valuation and financing attractiveness. |
| Metallurgical risk | DFS recovery is 78 percent. Actual plant performance must prove this at scale. |
| Open-pit mining risk | Strip ratio, dilution, grade control, pit stability, water management, and contractor performance will matter. |
| Resource/reserve risk | The production target includes 14 percent inferred material over life of mine, although less than 1 percent inferred material is used during the payback period. |
| Execution shift risk | Investigator is moving from study phase into development execution. Many juniors struggle during this transition. |
| Share price overhang | After a large placement, the market may need time to absorb new shares. |
Catalysts
| Timeline | Catalyst |
| 2026 | Progression of permitting and approvals |
| 2026 | High-density drilling in the early mining areas |
| 2026 | Paris pit expansion drilling |

| 2027 | Potential Final Investment Decision |
| 2027-2028 | Construction phase, depending on financing and permits |
| 2028 | Potential first silver production if execution proceeds according to the company timeline |
Expected Timeline to Full Production
| Timeline | Expected Progress |
| 2026 | Key de-risking year. The DFS is complete and the A$55M placement is done. Focus shifts to engineering, permitting, drilling, project optimisation, execution readiness, long-lead items, and financing preparation. |
| 2027 | Potential construction decision year if permitting, engineering, and financing are successfully completed. Watch for FID, project debt terms, offtake or strategic funding, and any additional equity requirement. |
| 2028 | Company timeline materials show silver production as a potential 2028 event. This depends on approvals, financing, construction, and commissioning proceeding without major delays. |
Valuation Summary
This is a simplified free cash flow valuation model. It uses the company’s DFS spot-case pre-tax net project cash flow as the base, then adds silver-price upside using the company’s stated sensitivity of A$42M life-of-project pre-tax net cash flow for every US$1/oz increase in silver price. It does not adjust for higher taxes, royalties, inflation, cost escalation, debt interest, financing cost, hedging, future dilution, schedule delays, or mine plan changes.

RT Rating, Commentary
Investigator Silver is on our watchlist.
We rated this as 4 out of 5 stars.
Investigator Silver checks many of the boxes we like in a silver developer: high-grade open-pit silver, 100 percent ownership, Tier 1 jurisdiction, completed DFS, maiden reserve, simple processing, strong silver leverage, institutional support and a management team now focused on execution.
The Paris Silver Project is not just an exploration dream anymore. It has moved into the serious development category. The DFS shows strong economics at US$60 silver and very powerful economics at US$80 silver. If silver enters a major bull market, IVR could become one of the cleaner pure-play silver torque names in Australia.
The biggest weakness is their cost structure and management ownership. We always like if the team got significant number. They their AISC and no infra will like causing more dilution in the future.
Overall, Investigator Silver looks like a high-quality, high-torque silver developer, but not a low-risk one. The upside is strong if silver stays high and Paris advances smoothly. The downside is that the market may punish delays, funding dilution, or execution mistakes.
