Eloro Resources Ltd. (TSX: ELO / OTCQX: ELRRF / FSE: P2QM)
Introduction
Eloro Resources Ltd. is a Canadian exploration and mine-development company focused primarily on the Iska Iska silver-tin polymetallic project in Potosí Department, southern Bolivia. The company also owns an 82% interest in the La Victoria gold-silver property in Peru and retains several earlier-stage exploration properties in Québec, Canada. Iska Iska is overwhelmingly the main investment story and is described in Eloro’s regulatory disclosure as its only material mineral project.
The story changed significantly in 2026. Eloro completed a major updated Mineral Resource Estimate with an effective date of April 2, 2026. The new estimate established an initial Indicated resource of 85.17Mt grading 40 g/t Ag, 1.21% Zn and 0.71% Pb, containing 109.53Moz of silver, alongside a very large 945.43Mt Inferred resource containing another 248.60Moz silver plus substantial zinc, lead, tin and gold. Silver grade in the newly defined Indicated resource increased 65% compared with the higher-grade near-surface Inferred resource reported in 2023.
The bull case is straightforward: Iska Iska is exceptionally large, the higher-grade core has now been converted partly into Indicated resources, some recent drilling has returned genuine high-grade silver and tin intervals, the optimized resource pit has an attractive approximately 1:1 strip ratio, and Eloro is now carrying out a major 40,000m expansion program as part of the PEA process.
The risk is equally important. Eloro still has no completed PEA, no mineral reserves, no official mine plan, no initial capex, no AISC, no NPV, no IRR and no production schedule. Iska Iska is also metallurgically more complicated than a straightforward silver mine because value must potentially be recovered from silver, zinc, lead and tin streams. On top of this, the flagship asset is in Bolivia, giving Eloro materially higher political, regulatory and social-risk exposure than an equivalent project in a Tier-1 jurisdiction.
Projects / Location / MRE / Grades
Project 1: Iska Iska Silver-Tin Polymetallic Project, Bolivia
Main Asset
Iska Iska is located approximately 48km north of Tupiza in the Sud Chichas Province of Potosí Department in southern Bolivia. It is road accessible and royalty-free. Following completion of the remaining option payments in January 2026, Eloro’s Bolivian subsidiary holds a 99% joint-venture interest, 100% economic participation and full operational control. The titleholder retains a 1% joint-venture interest to comply with Bolivian mining-law requirements.
This is important because one of the historical uncertainties surrounding Eloro was the option structure. The major Iska Iska acquisition payments have now been completed, meaning the project is substantially more cleanly controlled going into the PEA stage.
Geologically, Iska Iska is a very large silver-tin polymetallic porphyry-epithermal complex associated with a collapsed/resurgent caldera. The caldera itself is approximately 1.6km by 1.8km, while drilling and alteration indicate a much larger hydrothermal footprint that remains open laterally and at depth.
Most importantly, the June 2026 Micon technical report now treats silver as the primary or chief economic component of Iska Iska based on prevailing and long-term metal prices. This is a useful change for silver investors because older descriptions of Iska Iska often made it look primarily like an enormous zinc-lead-polymetallic deposit with tin optionality. The current MRE gives silver a much more central role.
Grade Feel
Iska Iska needs to be separated into two different stories.
The overall billion-tonne system is not high grade. The total Inferred resource averages only 8.5 g/t silver, although it contains meaningful zinc, lead, tin and gold credits. Looking only at the giant headline tonnage without considering grade would therefore exaggerate the quality of the deposit.
The more important development story is the higher-grade core. The new Indicated resource contains 85.17Mt grading:
- 40 g/t Ag
- 1.21% Zn
- 0.71% Pb
- 78.38 g/t AgEq
That is considerably more attractive than the average grade of the overall Inferred resource and is the part of the project most relevant to a potential starter-pit strategy.
Drilling has also demonstrated that substantially higher-grade zones exist inside the system. Hole DSB-93 returned 180m grading approximately 165 g/t Ag, including 72m grading 294.81 g/t Ag. Other holes have returned long tin, zinc and silver intervals. These high-grade shoots are what could ultimately transform a giant low-grade resource into a much better mine-development story if sufficient continuity can be demonstrated.
Iska Iska Mineral Resource Estimate
The current NI 43-101 Technical Report was prepared by Micon International and has an effective date of April 2, 2026 and report date of June 1, 2026.
| Resource Category | Tonnes | AgEq Grade | Ag Grade | Contained Ag | Zn Grade / Metal | Pb Grade / Metal | Sn | Au |
| Indicated | 85.17Mt | 78.38 g/t | 40 g/t | 109.53Moz | 1.21% / 1.03Mt | 0.71% / 0.60Mt | N/A | N/A |
| Inferred | 945.43Mt | 22.04 g/t | 8.5 g/t | 248.60Moz | 0.47% / 4.72Mt | 0.16% / 1.50Mt | 0.03% / 290kt | 0.04 g/t / 1.21Moz |
The figures above are based on Eloro’s April 2026 updated MRE.
Metallurgical Position
This section is worth adding to the original template because metallurgy is one of the biggest variables for Iska Iska.
For the 2026 resource model, Micon used estimated recoveries of approximately:
| Metal | Metallurgical Recovery Assumption |
| Zinc | 70.0% |
| Lead | 71.4% |
| Silver | 80.4% total |
| Tin | 40.4% into a 60% fume concentrate |
| Gold | 50% |
The silver recovery assumption is encouraging. Approximately 51.1% of silver is expected to report to the lead concentrate and another 29.3% to the zinc concentrate.
Tin remains more challenging. Concentrator-stage test work improved from approximately 50.7% recovery in the earlier program to 58.9% recovery into a roughly 4.8%-5% Sn concentrate, but the technical report makes clear that fine cassiterite and mineral liberation remain challenges.
Metallurgy feel: promising enough to advance, but not fully de-risked. The ultimate flowsheet, concentrate quality, treatment charges, payable metal and capital intensity could materially change future economics.
Current 2026 Expansion Program
In July 2026, Eloro officially commenced a 40,000m expansion diamond-drilling program of approximately 75 holes, using up to three Major Drilling rigs. The program is targeting expansion and upgrading of the Indicated resource, 50m-spaced drilling around the potential starter-pit core and extensions of known higher-grade silver-tin polymetallic shoots. Completion is expected during Q1 2027.
This is currently the single biggest exploration catalyst for ELO.
Project 2: La Victoria Gold-Silver Project, Peru
Secondary Optionality Asset
Eloro owns 82% of La Victoria, a gold-silver project in Ancash Department within Peru’s North-Central Mineral Belt. The property contains a number of gold and silver targets including San Markito, Rufina and Victoria.
However, investors should not give La Victoria a large valuation today.
Eloro’s latest available financial disclosure states that during the period ended September 30, 2025, the company recognized indicators of impairment because there were no substantive expenditures budgeted or planned and insufficient information to support technical feasibility or commercial viability. The property was therefore written down. Eloro still owns its interest, but economically I would currently assign only modest optionality value to it.
Project 3: Québec Properties, Canada
Non-Core / Legacy Optionality
Eloro also retains exploration properties in Québec, including Lac Henri, Delta, Eastmain and Lemoyne North in northern Québec greenstone belts. Delta and Eastmain are prospective for copper-gold mineralization, while Lemoyne North is primarily a gold target.
These properties provide some geographic diversification into a Tier-1 jurisdiction, but there is currently no comparable resource, development study or major exploration program that makes them meaningful relative to Iska Iska.
Share Structure / Ownership / Insiders
Capital Structure
Eloro’s company-reported capital structure as of May 5, 2026 was:
| Share Structure Item | Shares / Securities |
| Issued and Outstanding | 119.67M |
| Warrants | 10.82M |
| Options + RSUs + DSUs | 9.72M |
| Property Acquisition Shares | 0.20M |
| Fully Diluted | 140.41M |
| Debt | Nil |
Eloro’s investor page showed C$1.61 per share on July 3, 2026 and approximately C$226M fully diluted market capitalization. More recent market data around August 7-9 had the stock around C$2.00-C$2.03, although the price can obviously move quickly
At approximately C$2.03, that implies roughly:
- Basic market capitalization: C$243M
- Fully diluted market capitalization: C$285M
Recent Financing
In March 2026, Eloro completed a C$17.0M bought-deal financing, issuing 6,538,600 shares at C$2.60 per share. Proceeds were earmarked primarily for Iska Iska exploration and development plus working capital.
Ownership / Insider
Eloro’s current ownership graphic on its investor website shows approximately:
| Ownership | Approx. Share |
| Institutional | 32% |
| Insiders | 17% |
| Cartier Silver Corporation | 2% |
| Implied Retail | 49% |
Institutional ownership of around 32% is a positive because it indicates meaningful professional investor participation.
Insider ownership around 17% is respectable but not exceptionally high. It provides some alignment, where management and directors collectively control 20%.

Risks / Catalysts / Timeline
Key Risks
| Risk Category | Key Risk |
| No Completed PEA | There is still no official NPV, IRR, capex, AISC, production rate, mine life or payback period. |
| Resource Quality | 945Mt of the current resource is Inferred and much of it is lower grade. Large tonnage does not automatically mean high economic value. |
| Resource-to-Reserve Risk | Mineral resources are not mineral reserves and have not yet demonstrated economic viability. |
| Metallurgical Risk | Iska Iska requires multiple recovery routes for Ag, Zn, Pb and Sn. Tin recovery in particular remains technically challenging. |
| Concentrate / Payability Risk | Future concentrate quality, impurities, treatment charges and metal payabilities could materially affect economics. |
| PEA Risk | The eventual PEA could show higher capex, weaker recoveries, higher operating costs or lower returns than investors expect. |
| Bolivia Jurisdiction Risk | Political, regulatory, taxation, currency, social and permitting conditions are materially less predictable than in Tier-1 jurisdictions. |
| Logistics / Social Disruption | Recent Bolivian road blockades temporarily interrupted transportation before agreements reopened routes. |
| Financing Risk | A project of this scale will eventually require substantially more capital. |
| Dilution Risk | Eloro remains pre-revenue and additional equity issuance is likely before a construction decision. |
| Commodity Price Risk | Economics will depend on a basket of silver, zinc, lead and tin prices rather than silver alone. |
| Execution Risk | Management must move successfully from resource drilling into engineering, permitting, financing and development. |

Valuation
Resource-Stage Valuation Snapshot
Before using the FCF model, Eloro deserves an additional resource-stage valuation measurement because the company already controls a very large mineral resource but does not yet have a completed economic study.
The current Iska Iska MRE contains:
109.53Moz Indicated Ag + 248.60Moz Inferred Ag = approximately 358.13Moz contained silver.
At approximately C$2.03/share and 140.41M fully diluted shares, the fully diluted market capitalization is approximately C$285M, equivalent to roughly C$0.80 of market capitalization per contained silver ounce.
This comparison does not assign separate value to Iska Iska’s substantial zinc, lead, tin and gold inventory. At the same time, it does not account for recoveries, future capex, operating costs, metallurgical complexity, dilution or Bolivia jurisdiction risk.
For that reason, contained-silver valuation should be viewed only as a rough resource-stage screening method rather than a proper NAV calculation.
Contained-Silver Valuation Sensitivity
| Implied Value / Contained Ag oz | Implied FD Equity Value | Approx. CAD / Share |
| C$1.00/oz | C$358M | C$2.55 |
| C$2.00/oz | C$716M | C$5.10 |
| C$3.00/oz | C$1.07B | C$7.65 |
| C$4.00/oz | C$1.43B | C$10.20 |
FCF Margin Assumption
| Silver Price | Hypothetical AISC | FCF Margin / oz |
| US$150/oz | US$35/oz | US$115/oz |
| US$200/oz | US$35/oz | US$165/oz |
The model assumes:
FCF Margin per ounce = Silver Price − AISC
Therefore:
US$150 silver − US$35 AISC = US$115/oz FCF margin
US$200 silver − US$35 AISC = US$165/oz FCF margin
This remains deliberately simplistic. Iska Iska contains significant zinc, lead and tin that could provide important by-product credits and potentially lower the effective silver-equivalent cost structure. On the other hand, metallurgical complexity and future capital requirements could reduce actual free cash flow.
CAD Share Price Target — Per 1Moz Annual Production
| Silver Price | Annual Production | Annual FCF | 10x FCF CAD/share | 15x FCF CAD/share | 20x FCF CAD/share |
| US$150/oz | 1Moz/year | US$115M | C$10.89 | C$16.34 | C$21.79 |
| US$200/oz | 1Moz/year | US$165M | C$15.63 | C$23.44 | C$31.26 |
This means that under the model, every hypothetical 1Moz/year of silver-equivalent production becomes extremely valuable in a US$150-US$200 silver environment because the assumed US$35/oz cost base creates very large operating margins.
CAD Share Price Target — Production Sensitivity
| Annual Production | Silver Price | Annual FCF | 10x FCF CAD/share | 15x FCF CAD/share | 20x FCF CAD/share |
| 2Moz/year | US$150/oz | US$230M | C$21.79 | C$32.68 | C$43.57 |
| 2Moz/year | US$200/oz | US$330M | C$31.26 | C$46.89 | C$62.52 |
| 3Moz/year | US$150/oz | US$345M | C$32.68 | C$49.02 | C$65.36 |
| 3Moz/year | US$200/oz | US$495M | C$46.89 | C$70.33 | C$93.78 |
| 5Moz/year | US$150/oz | US$575M | C$54.47 | C$81.70 | C$108.93 |
| 5Moz/year | US$200/oz | US$825M | C$78.15 | C$117.22 | C$156.29 |

RT Rating, Commentary
Eloro Resources is not on our watchlist.
We rate this as 3 out of 5 stars.
Eloro Resources has one of the more unusual silver-development setups in the junior sector. Iska Iska is already enormous, with more than 109Moz of silver in Indicated resources and another 248Moz in Inferred resources, before considering the substantial zinc, lead, tin and gold inventory. The 2026 MRE is a major step forward because it establishes a sizeable higher-grade Indicated core rather than relying entirely on a giant lower-grade Inferred resource.
The strongest part of the story is increasingly the potential starter-pit zone. Intersections such as 180m grading approximately 165 g/t silver, including 72m grading nearly 295 g/t silver, prove that genuinely high-grade material exists inside the broader system. If the ongoing 40,000m drilling program can demonstrate continuity and expand those higher-grade zones, the economics of the project could look materially better than the overall billion-tonne resource grade suggests.
Management is another strong point. Eloro has a combination of capital-markets experience, former Champion Iron leadership, strong Bolivian geological expertise and highly experienced technical and corporate advisers. The company has also demonstrated an ability to raise meaningful amounts of capital, including the C$17M financing completed at C$2.60 in March 2026.
The reasons this does not receive a higher rating today are equally clear.
First, Iska Iska still does not have a completed PEA. We do not know the official mine size, annual production, capex, operating cost, AISC, NPV, IRR, mine life or payback.
Second, metallurgy is more complicated than a normal primary silver mine. Silver recovery looks encouraging, but tin remains technically challenging and the project will likely require multiple concentrate streams. So, basically they is still too early. Plus, we have doubt in their grade, as we always prefer purely high grade compared to mainly large resources. But in bull gold/silver market like now, we consider that will be fine.
