## Minestarters Atlas summary

1911 Gold reported positive metallurgical test results for its True North and Ogama-Rockland gold projects in Manitoba, Canada. The True North project achieved average gold recoveries of 93.7% from a 1.82 g/t Au sample, while preliminary test work for Ogama-Rockland yielded 96.3% gold recovery from a 4.65 g/t Au sample. Both projects demonstrated amenability to conventional gravity-flotation-leach processing with moderate reagent consumption and no deleterious elements, supporting future development plans.

Reasoning: The document reports high gold recoveries for both True North \(93.7%\) and Ogama-Rockland \(96.3%\) projects using conventional gravity-flotation-leach flowsheets, with moderate reagent consumption and no deleterious elements, confirming the amenability of the ore to processing. However, further variability testing is needed, and the True North sample grade is below the PEA cut-off.

- Positive factor: High gold recoveries achieved for both projects \(93.7% for True North, 96.3% for Ogama-Rockland\)

- Positive factor: Conventional gravity-flotation-leach flowsheet is effective

- Positive factor: Moderate to low reagent consumption

- Positive factor: No acid-generating or deleterious metal leaching potential identified

- Positive factor: QP/CP signed off on the results from a certified laboratory

- Negative factor: Test work is preliminary for Ogama-Rockland, and further variability testing is required for both projects

- Negative factor: True North sample head grade \(1.82 g/t Au\) is lower than the PEA cut-off grade \(2.75 g/t Au\), raising questions about representativeness of future mill feed

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

Reasoning: Preliminary test work for Ogama-Rockland achieved an exceptional 96.3% gold recovery from a high-grade sample using a conventional gravity-flotation-leach flowsheet, confirming the clean nature of the material. However, the preliminary nature and an assumption in the recovery calculation reduce confidence slightly.

- Positive factor: Exceptional gold recovery for Ogama-Rockland

- Positive factor: Conventional processing route confirmed

- Positive factor: High head grade of the sample

## 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.
