## Minestarters Atlas summary

Redcastle Resources Ltd \(RC1\) announced a maiden Mineral Resource Estimate for stockpiled gold at its Redcastle Gold Project, totaling 144,800 tonnes at 1.43 g/t Au for 6,600 oz. The majority of this, 6,500 oz, is classified as Measured Resource. While open pit mining commenced in May, it is currently suspended, and the company is actively pursuing processing arrangements for the stockpiled material.

Reasoning: Redcastle Resources has reported a substantial maiden Mineral Resource Estimate for its gold stockpiles, with a high proportion in the Measured category, indicating a ready source of material. However, the current suspension of mining and pending processing arrangements introduce some uncertainty regarding immediate monetization.

- Positive factor: Significant gold ounces in Measured stockpile resource

- Positive factor: JORC 2012 compliant estimate with QP sign-off

- Positive factor: Open pit mining has commenced

- Positive factor: Potential for conversion to Ore Reserves

- Negative factor: Mining currently suspended

- Negative factor: Processing arrangements not yet finalized

- Negative factor: No specific metallurgical testwork on the stockpile material

- Negative factor: High grade cuts applied to grade control data

Facts used in scoring: 9

#### Tags used in scoring

**Indicated Resource**

Polarity: positive

Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.

Why it applies: category is "indicated"

**Cut-off Disclosed**

Polarity: positive

Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: cutoff\_grade is stated

**QP/CP Signed**

Polarity: positive

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: qp\_signed is true

**JORC Compliant**

Polarity: positive

Definition: Resource estimate prepared in compliance with JORC Code \(Australia\) — high reporting standard.

Why it applies: reporting\_standards includes jorc

**Resource Update**

Polarity: neutral

Definition: Revised estimate for an existing resource — compare to prior to assess progress.

Why it applies: the release compares against a previous estimate

## 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.
