## Minestarters Atlas summary

Lion Copper and Gold announced significant drill results from its 2024 exploration program at the Bear deposit in Nevada, highlighted by hole B-056A which intersected 2,376 feet \(724.26 meters\) at 0.40% Total Copper \(TCu\). This intercept includes several higher-grade sub-intervals, confirming the large scale and potential of the porphyry copper system. The company also reported that hole B-055 encountered weak mineralization on the western edge of the deposit.

Reasoning: The 2024 drilling program, particularly hole B-056A, delivered a very long and high-grade copper intercept, which significantly confirms and expands the potential of the Bear porphyry deposit. This result is highlighted as the second-best grade-thickness intercept to date for the project.

- Positive factor: Exceptional intercept length and grade in B-056A

- Positive factor: Confirms and expands the porphyry copper system

- Positive factor: High grade-thickness value for B-056A

- Positive factor: Multiple high-grade sub-intervals within the main intercept

- Positive factor: Strong QA/QC disclosure and QP sign-off

- Negative factor: Hole B-055 encountered only weak mineralization

Facts used in scoring: 46

## 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 explicitly states that 'Commercially prepared certified reference materials and blanks were inserted by the Company at 50-ft intervals to ensure precision of results as a quality control measure' and 'The Company also applied a chain of custody program to confirm sample security during all stages of sample collection, shipment, and storage.'

> Commercially prepared certified reference materials and blanks were inserted by the Company at 50-ft intervals to ensure precision of results as a quality control measure. The Company also applied a chain of custody program to confirm sample security during all stages of sample collection, shipment, and storage.

**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: The technical information in this news release has been reviewed and approved by C. Travis Naugle, QP MMSA, Co-Chairman of Lion Copper and Gold Corp. and a qualified person as defined in NI 43-101.

**Bonanza Intercept**

Polarity: positive

Definition: Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: Hole B-056A encountered 2,376 ft \(724.26m\) of 0.40% TCu, which is an exceptional grade-width product for a porphyry copper deposit, and is described as the '2nd best grade-thickness intercept made to date at Bear'.

Evidence · text

> Diamond core drill hole B-056A encountered 2,376 ft of 0.40% TCu

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: B-056A was drilled to test a wide spaced drilling gap along the northwest mineralization trend identified previously by Anaconda legacy and SPS 2023 drill holes, indicating an extension of known mineralization.

Evidence · text

> B-056A was drilled to test a wide spaced drilling gap along the northwest mineralization trend identified previously by Anaconda legacy and SPS 2023 drill holes.

**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 reports downhole intercept lengths without explicitly stating true widths or providing sufficient information to infer them for the new drill holes.

## 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.
