## Minestarters Atlas summary

Amarc Resources announced significant expansion drill results from its AuRORA Copper-Gold-Silver Deposit, extending mineralization by up to 300 meters to the north, east, and southeast. The drilling, focused on step-out holes, continues to define the full extent of the high-grade porphyry system, which the company believes has Tier One asset potential. All reported intervals are downhole widths, with true thicknesses yet to be determined.

Reasoning: Amarc Resources announced highly positive drill results from expansion step-out drilling at the AuRORA Deposit, significantly extending high-grade copper-gold-silver mineralization to the north, east, and southeast. The results demonstrate exceptional continuity and high grades, with robust QA/QC procedures, though true widths remain unknown.

- Negative factor: true\_width\_undisclosed

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

## Classification and evidence

**Step-Out Extension**

Polarity: positive

Definition: Mineralization extended beyond the previously known limit.

Why it applies: The drill program was primarily focused on continuing to define the full extent of the AuRORA Deposit, with 23 expansion step-out holes that expanded the deposit to the north, east, and southeast.

Evidence · text

> 23 of these are expansion step-out holes drilled over an area measuring some 1 km by 1 km. ... expanded AuRORA a further +100 m to the north ... expand the deposit approximately 200 m to the east ... expanded the deposit approximately 300 m to the southeast

**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 the QA/QC program, including the use of ISO/IEC 17025:2017 accredited labs \(ALS Canada Ltd.\), insertion of standards, duplicate sets, and blanks, and review by a Qualified Person \(Mark Rebagliati, P.Eng.\).

Evidence · text

> All drill core was logged, photographed, and cut in half with a diamond saw. Half core samples from the JOY AuRORA drilling were sent to ALS Canada Ltd., Kamloops, Canada, for preparation and to North Vancouver, Canada for analysis. Both facilities are ISO/IEC 17025:2017 accredited. ... As part of a comprehensive Quality Assurance/Quality Control \("QAQC"\) program, Amarc control samples were inserted in each analytical batch of the core samples at the following rates: standards one in 20 regular samples, duplicate sets \(half core, coarse reject, and pulp split\) one in 20 regular samples and one coarse blank in 20 regular samples. The control sample results were then checked to ensure proper QAQC. Mark Rebagliati, P.Eng., a Qualified Person \("QP"\) as defined by National Instrument 43-101, has reviewed and approved the technical and scientific information in this news release.

**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 notes to Table 1 explicitly state that widths reported are drill widths and true thicknesses are unknown.

Evidence · text

> Widths reported are drill widths, such that true thicknesses are unknown.

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept in hole JP25103 of 1.80m at 999.0 g/t Ag is exceptionally high-grade, well above the typical thresholds for silver.

Evidence · table

> 999.0

Context: 1.80

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept in hole JP25109 of 200.95m at 1.38 g/t Au and 0.27% Cu represents an exceptional gold grade over a continuous width for a porphyry deposit.

> 1.38

Context: 200.95

**Bonanza Intercept**

Polarity: positive

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

Why it applies: The intercept in hole JP25107 of 201.00m at 1.40 g/t Au and 0.28% Cu represents an exceptional gold grade over a continuous width for a porphyry deposit.

## 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.
