## Minestarters Atlas summary

Oroco Resource Corp. reported the third set of assay results from its Phase 2 resource drilling program at the Santo Tomás copper project in Sinaloa, Mexico. The program confirmed and extended mineralization in the South Zone, with notable intercepts including 26.48m at 0.90% Cu / 1.18% CuEq from 48m depth in hole S033. Drilling also extended mineralization westward beyond current inferred block model limits and helped define the southern limit of the South Zone, supporting resource conversion and future PFS planning.

Reasoning: The drill results confirm and extend copper mineralization in the South Zone, with notable higher-grade intercepts, supporting the company's resource conversion and expansion objectives. Strong QA/QC disclosure enhances confidence, though the lack of CuEq for some intervals and unconfirmed true widths introduce minor limitations.

- Positive factor: Confirmation and extension of mineralization beyond current inferred block model limits

- Positive factor: Higher-grade near-surface intercept in hole S033

- Positive factor: QA/QC procedures and QP sign-off disclosed

- Positive factor: Drilling supports resource conversion and potential tonnage increase

- Negative factor: CuEq not reported for all mixed oxide/sulphide intervals, limiting comparability

- Negative factor: True widths are not yet confirmed for all reported intervals

- Negative factor: Compositing cut-off grade for significant intervals is not explicitly stated

Facts used in scoring: 61

## Classification and evidence

**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 details QA/QC protocols including certified reference standards, blanks, duplicates, and specific assay methods by ALS Chemex and ALS Canada Ltd.

Evidence · text

> Quality Assurance / Quality Control ... Drill collar locations are verified by differential GPS with checks against LiDAR data. Geological logging, core sampling, sample preparation, analysis, and chain of custody are governed by QA/QC protocols that include the insertion of certified reference standards, blanks, and duplicates. Samples are submitted to ALS Chemex \(Hermosillo, Mexico\) for sample preparation; pulps are sent to ALS Canada Ltd. \(Vancouver\) for analysis.

**QP/CP Signed**

Polarity: positive

Story-specific tag

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: Andrew Ware, RM-SME, a Qualified Person as defined in NI 43-101, has reviewed and approved the technical disclosures.

Evidence · text

> Andrew Ware, RM-SME, a Qualified Person as defined in NI 43-101 — Standards of Disclosure for Mineral Projects, and a senior consulting geoscientist to the Company, has reviewed and approved the technical disclosures in this news release.

**Metal Equivalent Opaque**

Polarity: negative

Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Requires an actual metal equivalent grade; a combined elemental basket such as PGE is not a metal equivalent.

Why it applies: CuEq calculations use variable metal recovery curves and ranges \(e.g., Cu 82-89%, Mo 50-60%, Au 30-85%, Ag 35-67%\) rather than specific recovery values for each interval, making individual interval assessment less transparent.

Evidence · text

> Metal recoveries are grade-based by individual assay in the reported intervals and vary accordingly. In these intervals, Cu recovery ranges from 82-89%, Mo 50-60%, Au 30-85% and Ag 35-67%.

**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: All reported intervals are downhole drill core lengths, and true widths are stated to be confirmed later.

Evidence · text

> All intervals are downhole drill core lengths. True widths will be confirmed when Phase 2 results are incorporated into the updated geological and resource models.

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: The document states 'Significant Intervals comprise intervals ≥ 10m of ≥ 0.15% Cu, but may include assay intervals of ≤ 4m of ≥ 0.05% Cu' as a reporting threshold, but does not disclose the actual compositing cut-off grade used.

Evidence · text

> Significant Intervals comprise intervals ≥ 10m of ≥ 0.15% Cu, but may include assay intervals of ≤ 4m of ≥ 0.05% Cu.

#### Review

- Needs Review: No
- Interp. Status: scored
- Historical: No

#### Dates

- Event date: 2026-08-06T00:00:00.000Z

Reasoning: Expanded from assay table. 2.49 g/t silver is weak against the default band \[500, 200, 100, 30\] g/t. Grade×width 285.6 g/t·m is weak \(grade alone is below; the better of the two is used\).

- Negative factor: Scored from rubric bands during table expansion, not from document context.

#### Tags used in scoring

**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: qaqc\_disclosed is true

**Cut-off Undisclosed**

Polarity: negative

Definition: High-grade interval reported without stating the cut-off grade used for compositing.

Why it applies: no cutoff\_grade was stated

#### Metal Equivalent

- Metal Eq. Grade: 0.39
- Metal Eq. Unit: % CuEq
- Assumptions Disclosed: Yes

#### Review

- Needs Review: No
- Interp. Status: scored
- Historical: No

#### Dates

- Event date: 2026-08-06T00:00:00.000Z

Reasoning: Expanded from assay table: 0.011 % molybdenum. No grade band defined for this commodity, so the score is a placeholder.

- Negative factor: No grade rubric for molybdenum; intercept not scored.

## 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.
