## Minestarters Atlas summary

Black Mammoth Metals has completed the 100% acquisition of the America Mine gold property in San Bernardino County, CA. The property features an open pit heap leach opportunity and includes historical reserve estimates from 1997, though these require modern NI 43-101 verification.

Reasoning: The company has acquired a gold property with existing historical reserves, but the data is outdated and requires modern verification.

- Positive factor: 100% ownership with no royalties

- Positive factor: Open pit heap leach opportunity

- Positive factor: Existing infrastructure \(water and power\) available

- Negative factor: Historical reserves are not NI 43-101 compliant

- Negative factor: Lack of detailed documentation for historical data

- Negative factor: Requires significant work to verify/upgrade to current standards

Facts used in scoring: 2

## Classification and evidence

**Historical Estimate Only**

Polarity: negative

Definition: Estimate pre-dates or does not comply with current JORC/NI 43-101 standards — requires verification drilling.

Why it applies: The reserves reported are from a 1997 MDA report and are not NI 43-101 compliant.

Evidence · text

> Black Mammoth is not considering the historical estimates as current mineral reserves due to insufficient work by a qualified person

**No QP/CP Disclosure**

Polarity: negative

Definition: No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience.

Why it applies: The historical estimates were completed using outdated methodologies and lack modern verification/documentation.

Evidence · text

> The inability to verify the data stems from the historical reserves being estimated using outdated methodologies and standards

## 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.
