Summary
Loncor Gold has released final drill assays from its deepest borehole, LADD029, at the Adumbi deposit in the DRC. The results include several high-grade gold intercepts, including 4.64 m at 5.83 g/t Au, which support the potential for a significant underground resource below the existing open pit.
Reasoning: The release reports final assays for the deepest hole (LADD029), confirming high-grade gold mineralization at depth and expanding the potential for an underground resource, though some intercepts were previously reported.
Positive factors
- Significant gold grades at depth
- Demonstrates underground potential
- Thickening BIF host package
- QA/QC disclosed
Negative factors
- Partial re-release of historical data
Facts used in scoring: 9
Classification and evidence
QA/QC Disclosedpositive
Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
Why it applies: Release includes details on standards, blanks, duplicates, and SGS laboratory use.
Evidence · text
“internationally recognized standards, blanks and duplicates were inserted into the sample batches”
Infill Drillingneutral
Confirmatory drilling to raise resource confidence, not new discovery.
Why it applies: The release mentions that borehole LADD029 results were reported previously, indicating this is a completion of existing work.

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.
