## Minestarters Atlas summary

Mammoth Resources reported drill results from four new holes at its Tenoriba gold-silver property in Mexico, highlighted by 85.7 metres grading 0.47 g/t gold equivalent in hole TEN 21-16. The results continue to demonstrate broad, potentially economic gold-silver mineralization, supporting a bulk, open-pit mining scenario and extending mineralization in the Carneritos area. The company noted an exceptional success rate in intersecting mineralization despite significant step-outs.

Reasoning: Mammoth Resources reported significant gold-silver equivalent intercepts from new drill holes at its Tenoriba property, including 85.7m at 0.47 g/t AuEq, extending mineralization in the Carneritos area. The results support a bulk, open-pit, heap-leach mining scenario, with high confidence due to disclosed QA/QC and QP sign-off, despite some operational delays and apparent width reporting.

Facts used in scoring: 103

## Classification and evidence

**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, 'Intervals shown are core lengths versus perpendicular, true widths of these mineralized features,' indicating that true widths are not reported for the intercepts.

Evidence · text

> Intervals shown are core lengths versus perpendicular, true widths of these mineralized features.

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The company mentions 'blocking off areas hundreds of metres up to over a kilometre in size via significant step-outs from sparse historical drilling,' indicating that the drilling is extending mineralization.

Evidence · text

> The success of this drilling is enabling Mammoth to block off areas hundreds of metres up to over a kilometre in size via significant step-outs from sparce historical drilling.

**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 'Qualified Person / Quality Controls' section, mentioning ALS laboratories, sample preparation, assay methods, and insertion of blanks and duplicates.

Evidence · text

> Qualified Person / Quality Controls: Richard Simpson, P.Geo., Vice-President Exploration for Mammoth Resources Corp. is Mammoth's Qualified Person, according to National Instrument 43-101 for the Tenoriba property and is responsible for and has reviewed any technical data mentioned in this news release. Samples referenced in this press release were prepared and analyzed by ALS laboratories \(ALS\) in their facilities in Mexico and Canada, respectively. Samples generally consisted of a minimum of 2 kilograms of material. Drill core is mostly HQ diameter core with minor lengths of NQ diameter core. Core is sawn in half with a rock saw with one half used for sample analysis purposes. Where samples are taken these are most often 1.5 metres in length, only in poor recovery sections do they exceed this length, with rare exceptions exceeding a maximum of 4.5 metres in length. Samples are collected with sample ticket and deposited into plastic sample bags sealed with nylon zip lock ties, then loaded into grain sacs similarly sealed with a nylon zip lock tie prior to transport by Mammoth personnel to ALS’s facility in Chihuahua, Mexico for sample preparation. Gold and silver analyses are performed in ALS’s facility in Canada via a 30-gram fire assay with an atomic absorption finish. Silver, copper, lead and zinc are analyzed as part of a multi-element ICP package using a 4-acid digestion. Any over limit samples with greater than one percent copper, lead and zinc are re-analyzed using ore grade detection limits. Blank and duplicate samples are inserted randomly at approximately every 15 samples.

**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: Richard Simpson, P.Geo., Vice-President Exploration for Mammoth Resources Corp. is named as Mammoth's Qualified Person and is responsible for and has reviewed the technical data.

Evidence · text

> Richard Simpson, P.Geo., Vice-President Exploration for Mammoth Resources Corp. is Mammoth's Qualified Person, according to National Instrument 43-101 for the Tenoriba property and is responsible for and has reviewed any technical data mentioned in this news release.

**Cut-off Undisclosed**

Polarity: negative

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

Why it applies: The document reports drill intervals and grades but does not state the cut-off grade used for compositing these intervals.

Evidence · text

> A summary of potentially economical intervals from the four drill holes from this press release are as follows.

**Heap Leach Route**

Polarity: neutral

Story-specific tag

Definition: Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.

Why it applies: The company explicitly states that the characteristics of the mineralization 'continue to favour a bulk, open pit mining and heap leach gold extraction operation'.

Evidence · text

> these characteristics all continue to favour a bulk, open pit mining and heap leach gold extraction operation

**Epithermal Deposit**

Polarity: neutral

Story-specific tag

Definition: No canonical definition is currently available.

Why it applies: The document describes the target as an 'epithermal High Sulphidation \(HS\) precious metal mineralized system' in multiple instances.

Evidence · text

> Carneritos-like epithermal High Sulphidation \(HS\) precious metal mineralized system

## 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.
