## Minestarters Atlas summary

Tali Resources Ltd announced the commencement of a 9,000m aircore drilling program at its Don Juan Critical Minerals Prospect in Western Australia, targeting rare earth elements and other critical minerals. The program will test high-priority targets within a 45km-long alkaline intrusive system, building on historical drilling that intersected aillikite, a rock type commonly associated with carbonatites. While the current announcement focuses on planned work, it also provides historical drill results and rock chip data that indicate prospectivity for REE and other metals.

Reasoning: Tali Resources announced the commencement of a significant 9,000m aircore drilling program targeting critical minerals in the West Arunta Project, supported by historical geological indicators and drill results, which is a positive step for exploration but lacks new assay data.

- Positive factor: Announcement of a significant 9,000m aircore drilling program.

- Positive factor: Drilling targets high-priority areas within a 45km-long alkaline intrusive system.

- Positive factor: Historical drilling intersected aillikite, a rock type associated with carbonatites and critical minerals.

- Positive factor: Highly anomalous rare earth-bearing rock-chip samples provide further evidence of prospectivity.

- Positive factor: Exploration results are compiled by a Competent Person \(Mr. John McIntyre\) who is a Member of the Australian Institute of Geoscientists.

- Positive factor: Historical RC drilling samples were subject to chain of custody procedures and inserted CRMs and blanks.

- Negative factor: The drilling program is planned to commence, so no new assay results are reported in this announcement.

- Negative factor: Historical drill results are re-reported and not new assays from the current program.

- Negative factor: True and apparent widths for historical RC drilling have not been interpreted, which limits geological understanding.

- Negative factor: Some historical rock chip and soil sampling QA/QC methods are not documented.

- Negative factor: Some areas are no longer accessible due to heritage approvals, potentially limiting future exploration.

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

Reasoning: A historical, broad intercept of REE+Y above cutoff is positive for prospectivity, but its novelty is low and the lack of true width information reduces confidence.

- Positive factor: Reported grade of 853 ppm REE+Y exceeds the 800 ppm cutoff grade.

- Positive factor: Intercept length of 19m indicates a broad zone of mineralization.

- Positive factor: Historical results are presented with QA/QC disclosure and Competent Person sign-off.

- Negative factor: This is a historical result, not new information from the current program.

- Negative factor: True width is not reported, limiting understanding of the actual thickness.

- Negative factor: The hole is vertical \(dip -90\), which can be problematic for steeply dipping structures.

- Positive factor: Historical results are presented with QA/QC disclosure and Competent Person sign-off.

- Negative factor: This is a historical result, not new information from the current program.

- Negative factor: Intercept length of 8m is moderate.

- Negative factor: True width is not reported, limiting understanding of the actual thickness.

- Negative factor: The hole is vertical \(dip -90\), which can be problematic for steeply dipping structures.

## 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.
