Minestarters Atlas analysis
Summary
Hannan Metals reported the first drill results from its Belen project in Peru, testing both epithermal gold and porphyry copper-molybdenum targets. While the Vista Alegre epithermal holes missed the main structure, the Ricardo Herrera porphyry hole (HDDRH001) intercepted chalcopyrite and molybdenite, and high-grade gold boulders were identified nearby.
Reasoning: The release reports pioneering drill results in a new district. While the epithermal target (Vista Alegre) missed the main structure, the porphyry target (Ricardo Herrera) shows encouraging visual mineralization and the presence of high-grade boulders nearby provides strong exploration upside.
Positive factors
- First-ever drilling of a new back-arc porphyry and epithermal system
- Visual mineralization (chalcopyrite/molybdenite) in first porphyry hole
- High-grade gold boulders (up to 2.72 g/t Au) located proximal to drilling
- Geophysical anomalies (IP/resistivity) suggest significant targets remain
Negative factors
- Vista Alegre holes failed to intersect the main mineralized structure
- Gold grades at Vista Alegre are low (up to 0.4 g/t Au) and likely surficial
Facts used in scoring: 6
Classification and evidence
Step-Out Extensionpositive
Mineralization extended beyond the previously known limit.
Why it applies: First-ever drilling of these back-arc porphyry and epithermal systems in a new district.
Evidence · text
“representing the first-ever drill testing of these back-arc porphyry and epithermal systems”
QA/QC Disclosedpositive
Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
Why it applies: Release details sample preparation, lab methods (ICP-MS, fire assay), and use of CRMs and check samples.
Evidence · text
“includes routine use of CRM and field duplicates as well as 10% check samples analyzed by ALS Lima”
Apparent Width Onlynegative
Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.
Why it applies: The document explicitly states that true widths of mineralization are not yet known.
Evidence · text
“At this stage true widths of mineralization are not known.”

Reasoning: Grades are low and interpreted as restricted to the upper regolith.
Negative factors
- Low grade
- Surficial enrichment
Evidence · text
“Drill holes returned up to 0.4 g/t Au, interpreted as surficial enrichment restricted to the upper 90 m regolith profile.”

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.
