## Minestarters Atlas summary

Mundoro Capital announced initial drill results from its Phase I program at the Dos Cabezas Project in Arizona, confirming porphyry-style mineralization. Scout drilling at the Mescal Canyon and Mineral Park targets intersected multiple zones of copper, gold, molybdenum, and silver. Highlights include a high-grade skarn intercept of 14.6m at 64.7 g/t Ag, 0.5 g/t Au, and 0.15% Cu, and a narrow 1.8m interval at 0.4% Cu at the bottom of hole DC\_004.

Reasoning: Mundoro's inaugural drill program at Dos Cabezas confirmed porphyry-style mineralization and identified a high-grade skarn zone, providing encouragement for further exploration despite generally low grades in the broader porphyry intercepts. The results are novel as first-pass drilling, but the early stage and mixed grades temper overall enthusiasm.

- Positive factor: Initial drilling confirmed mineralization consistent with a porphyry system, supporting further exploration potential.

- Positive factor: High-grade silver and gold intercept in skarn-style mineralization at Mescal Canyon.

- Positive factor: A narrow, high-grade copper intercept at the bottom of hole DC\_004 suggests proximity to a mineralized core.

- Negative factor: Most porphyry-style intercepts show low copper grades, below typical economic thresholds for bulk tonnage.

- Negative factor: Drilling was terminated short of target depth in DC\_003 due to external factors, leaving deeper potential untested.

- Negative factor: Intervals are reported as downhole lengths with no true width estimates, which may overstate actual thickness.

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

## 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 includes a detailed 'Sampling, Analysis and Quality Assurance and Quality Control \(QAQC\)' section, naming ALS as the laboratory and outlining methods like blanks, duplicates, standards, and re-assays.

Evidence · text

> Sampling, Analysis and Quality Assurance and Quality Control \(QAQC\) Drill core was transported from the drill platform to the logging facility where it was logged, photographed, processed and split by diamond saw prior to being sampled. Samples were taken approximately every 3 meters or at lithologic or mineral breaks then bagged, and blanks, duplicates and certified reference materials inserted at intervals of 1 QAQC sample every 10 samples. Groups of samples were placed in collection bags, sealed with numbered tags in order to maintain a chain-of-custody, and transported from the logging facility to the ALS preparatory laboratory in Tucson, Arizona. Sample preparation was carried out at ALS, Tucson. Analytical work for this drill program was carried out by ALS Reno for Au and Vancouver, Canada for multi-element geochemistry. Samples were prepared for analysis according to ALS method PREP 31, individual samples were crushed to 70% less than 2mm, rotary split off 1kg, pulverize split to better than 85% passing 75 microns is applied. Gold in samples were analyzed using ALS method Au AA24 where 50g split is analyzed with fire assay by Pb collection and AAS finish. Multi-element geochemical analysis \(48 elements\) was performed on all samples using ALS method ME-MS61 where a 50g split is by four-acid digestion with ICP-MS finish. For samples returned >1% Cu from the ME-MS61 method to be re-assayed using 4-acid digestion and AAS finish, lab code Cu-OG62. For samples returned >100ppm Ag from the ME-MS61 method to be re-assayed using 4-acid digestion and AAS finish, lab code Ag-OG62. Quality Assurance and Quality Control procedures include the systematic insertion of standards, blanks and duplicates into the sample process. Duplicate core samples are taken every 30 samples and standards or blanks and duplicates are inserted after every 10th sample. All data collected from detailed logging and assay results from the laboratories are verified and entered into a database with any samples failing QAQC reassayed along with samples related to the QAQC sample batch either side.

**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 reported drill intercepts are given as downhole lengths without any mention of true width or drill orientation relative to mineralization.

Evidence · text

> Table 1: Selected intervals from the drilling program completed at Dos Cabezas at Mescal Canyon \(DC\_003\) and Mineral Park \(DC\_004\) with intervals in meters and weighted averages reported.

**Nearology Play**

Polarity: neutral

Definition: Value premise rests on proximity to a known deposit rather than own results.

Why it applies: The project's location is highlighted by its proximity to known porphyry districts, suggesting its value is partly derived from this regional context.

Evidence · text

> The Dos Cabezas Project is surrounded by known porphyry districts, including Safford and Morenci to the north, and Tyrone to the east.

**Cut-off Undisclosed**

Polarity: negative

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

Why it applies: While some specific copper zones mention a >0.1% Cu threshold, a general cut-off grade for compositing the reported intervals is not explicitly stated.

Reasoning: The gold grade in this narrow intercept is low for a porphyry system, contributing minimally to the overall prospectivity.

- Negative factor: Gold grade is below the 'weak' threshold for porphyry deposits.

- Negative factor: Very narrow intercept length.

- Negative factor: Interval reported as downhole length, true width not stated.

#### 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

## 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.
