## Minestarters Atlas summary

Tinka Resources provided an exploration update for its Ayawilca zinc-silver and Silvia copper-gold projects in central Peru. The company plans a magnetotellurics geophysical survey at Silvia and a 5,000-meter drill program at Ayawilca in Q3 2026, following a revised geological interpretation that identified new high-grade silver vein targets. Additionally, Tinka is re-evaluating the historical Colquipucro silver deposit due to significantly higher silver prices.

Reasoning: Tinka Resources is highlighting exploration progress by re-interpreting historical data to define new high-grade silver targets at Ayawilca, planning future drill programs and geophysical surveys, and re-evaluating a historical silver resource in light of current prices. While much of the data is historical, the new interpretation and planned work provide a positive outlook for future exploration and potential resource growth.

- Positive factor: Identification of new high-grade silver vein targets at Ayawilca through re-interpretation of historical data.

- Positive factor: Planned ~5,000-meter drill program at Ayawilca to target these high-grade zones and for resource conversion/extension.

- Positive factor: Planned magnetotellurics \(MT\) geophysical survey at Silvia to identify deep copper-gold targets.

- Positive factor: Re-evaluation of the historical Colquipucro silver deposit in light of significantly higher current silver prices.

- Positive factor: Strong community relations and renewed social agreement for the Ayawilca Project.

- Negative factor: Most drill results presented are historical, with some previously unreported historical data lacking original release dates.

- Negative factor: The Silvia drill results mentioned are also historical and referenced a prior news release.

- Negative factor: The Colquipucro resource estimate is stale, dating back to 2016.

- Negative factor: True widths for drill intercepts are estimated, not explicitly stated, which may overstate apparent thickness.

- Negative factor: Channel samples lacked internal QA/QC \(no standards or blanks inserted by Tinka\).

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

Facts used in scoring: 34

## Classification and evidence

**Stale Data Re-release**

Polarity: negative

Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty.

Why it applies: The document presents historical drill results from 2016-2018 and a resource estimate from 2016, explicitly stating they are historical or previously reported.

Evidence · text

> Table 1 highlights some of the previous drill hole intercepts in the Silver Zone veins at West Ayawilca and original news release dates.

**Apparent Width Only**

Polarity: negative

Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: The document states that 'True thicknesses are estimated to between 50% and 70% of the downhole thicknesses' but does not provide specific true widths for each intercept.

Evidence · text

> True thicknesses are estimated to between 50% and 70% of the downhole thicknesses.

**No QA/QC Disclosure**

Polarity: negative

Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document.

Why it applies: For recent channel samples, the document explicitly states 'No standards or blanks were inserted by Tinka'.

Evidence · text

> No standards or blanks were inserted by Tinka.

**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: Dr. Graham Carman, President and CEO, is stated to be a Qualified Person as defined by NI 43-101 and has verified, reviewed and approved the technical contents of this release.

Evidence · text

> Dr. Graham Carman, Tinka's President and CEO has verified, reviewed and approved the technical contents of this release. Dr. Carman is a Fellow of the Australasian Institute of Mining and Metallurgy, and is a Qualified Person as defined by National Instrument 43-101.

**NI 43-101 Compliant**

Polarity: positive

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

Why it applies: The Colquipucro Mineral Resource Estimate is referenced as being reported in a 'NI 43-101 technical report'.

Evidence · text

> The Company filed a NI 43-101 technical report 1 on an updated PEA for the Ayawilca Project on April 15, 2024

**Inferred Resource**

Polarity: negative

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

Why it applies: The Colquipucro resource estimate includes 'inferred resources of 8.5 Mt grading 48 g/t Ag containing 13.2 Moz silver'.

Evidence · text

> inferred resources of 8.5 Mt grading 48 g/t Ag containing 13.2 Moz silver

**QA/QC Disclosed**

Polarity: positive

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: The release mentions that 'Standards and blanks with known values were inserted into each batch' for historic drill samples and that 'All drill samples were sent to SGS laboratories in Lima for assay'.

Evidence · text

> Standards and blanks with known values were inserted into each batch prior to departure from Tinka's core storage facilities for QA/QC purposes. At the laboratory samples are dried, crushed to 100% passing 2mm, then 500 grams pulverized for multi-element analysis by ICP using multi-acid digestion. Samples assaying over 1% zinc, lead, or copper and over 100 g/t silver are re-assayed using precise ore-grade AAS techniques.

## 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.
