## Minestarters Atlas summary

Eloro Resources announced an updated Mineral Resource Estimate for its Iska Iska project in Bolivia, reporting a maiden Indicated resource of 85.17 Mt grading 40 g/t Ag, 1.21% Zn, and 0.71% Pb. The overall Inferred resource increased by 41% to 945.43 Mt, containing 248.60 Moz Ag, 4.72 Mt Zn, 1.50 Mt Pb, 290,000 t Sn, and 1.21 Moz Au. The update also noted a 65% increase in silver grades in the Indicated category compared to the previous Inferred estimate, and improved tin recoveries from metallurgical testing.

Reasoning: The updated MRE demonstrates significant growth and de-risking for the Iska Iska project with the establishment of a maiden Indicated resource, substantial tonnage and grade increases, and improved tin recoveries, despite a large Inferred component and some metallurgical complexities.

- Positive factor: Maiden Indicated Mineral Resource established

- Positive factor: Significant increase in overall Inferred tonnage \(41%\)

- Positive factor: Substantial increase in silver grade \(65%\) in the Indicated category

- Positive factor: Contained metal growth across multiple commodities in both Indicated and Inferred categories

- Positive factor: NI 43-101 compliant and QP signed estimate

- Positive factor: Improved tin recovery from metallurgical testing

- Negative factor: A large portion of the resource remains in the Inferred category

- Negative factor: Contained silver and lead in the Inferred category decreased due to upgrade to Indicated

- Negative factor: Low metallurgical recoveries for tin \(40.4%\) and gold \(47.5%\) used in the MRE

- Negative factor: Tin processing involves fuming, suggesting metallurgical complexity

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 40

Evidence · text

> 41% increase in total tonnage with respect to the 670 Mt of overall Inferred mineral resources in the Initial 2023 MRE

**Grade Improvement**

Polarity: positive

Definition: Average resource grade improved vs prior estimate — better deposit economics.

Why it applies: Silver grades increased 65% from 24.3 g/t Ag reported in the near-surface Inferred resource category in the 2023 Initial MRE to 40 g/t Ag reported in the Indicated resource category in the 2026 Updated MRE.

Evidence · text

> Silver grades increased 65% from 24.3 g/t Ag reported in the near-surface Inferred resource category in the 2023 Initial MRE to 40 g/t Ag reported in the Indicated resource category in the 2026 Updated MRE.

**Contained Metal Growth**

Polarity: positive

Definition: True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes.

Why it applies: The Indicated category now contains 109.53 Moz Ag, 1.03 Mt Zn, and 0.60 Mt Pb, which were 'Nil' in the 2023 MRE, and Inferred contained tin increased from 0.13 Mt to 0.29 Mt.

Evidence · table

> 109.53

Context: Nil

**QP/CP Signed**

Polarity: positive

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: The MRE was 'prepared by independent qualified persons \('QPs'\) with Micon International Limited' and names Charley Murahwi, P.Geo., FAusIMM and Richard Gowans, P.Eng. as responsible QPs.

Evidence · text

> prepared by independent qualified persons \("QPs"\) with Micon International Limited

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: The document states 'The optimization indicates a cut-off grade of 11.14 g/t silver equivalent \(AgEq\)'.

Evidence · text

> The optimization indicates a cut-off grade of 11.14 g/t silver equivalent \(AgEq\)

**NI 43-101 Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard.

Why it applies: The Updated MRE 'has been prepared by independent qualified persons \('QPs'\) with Micon International Limited \('Micon'\), as defined under National Instrument 43-101 \('NI-43-101'\)'.

Evidence · text

> defined under National Instrument 43-101 \("NI-43-101"\)

**Recovery Improving**

Polarity: positive

Definition: Recovery improved versus a like-for-like prior test program on the same domain and route.

Why it applies: The overall tin recovery improved with further metallurgical testing from 50.7% in 2023 to 58.9% in the Updated 2026 MRE.

Evidence · text

> The overall tin recovery into a 5% Sn concentrate improved with further metallurgical testing from 50.7% in 2023 to 58.9% in the Updated 2026 MRE.

**Inferred Resource**

Polarity: negative

Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.

Why it applies: The document reports a large 'Inferred Category of 945.43 million tonnes'.

Evidence · text

> Inferred Category of 945.43 million tonnes

**Contained Metal Decline**

Polarity: negative

Definition: Contained metal decreased vs prior despite tonnage growth — grade dilution exceeds volume gain.

Why it applies: Inferred Silver contained metal decreased from 298.68 Moz to 248.60 Moz \(-16.77%\) and Inferred Lead decreased from 1.74 Mt to 1.50 Mt \(-14.37%\), though this is attributed to upgrading to the Indicated category.

Evidence · table

> -16.77\*

Context: 248.60

**Low Recovery**

Polarity: negative

Definition: Recovery below the weak band for the commodity and processing route.

Why it applies: Metallurgical recoveries used in the MRE are 40.4% for Sn and 47.5% for Au, which are below the weak band for these commodities.

Evidence · text

> Sn = 40.4%

**Refractory Ore**

Polarity: negative

Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk.

Why it applies: The processing route for tin includes 'fuming', which suggests a complex metallurgical process often associated with refractory ores.

Evidence · text

> Sn = 40.4% \(includes preconcentration, concentration and fuming\).

**Byproduct Commodity**

Polarity: neutral

Definition: The tested commodity is a byproduct rather than the primary economic driver.

Why it applies: The resource is described as 'Ag-Sn-polymetallic', indicating that Sn, Pb, Zn, and Au are present alongside the primary silver.

Evidence · text

> Ag-Sn-polymetallic

**Resource Update**

Polarity: neutral

Why it applies: The document is titled 'Eloro Resources Reports Substantial Resource Growth in Updated Mineral Resource Estimate'.

Evidence · text

> Updated Mineral Resource Estimate

**PEA-Supporting**

Polarity: neutral

Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.

Why it applies: The CEO states that the MRE 'will be detailed in the planned PEA'.

Evidence · text

> which will be detailed in the planned PEA.

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: the document describes a flotation route \("concentrate"\)

## How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
