Summary
Hot Chili Limited released its annual Mineral Resources and Ore Reserves statement for the Costa Fuego Project as of June 30, 2026. The statement confirms previously reported estimates, with no material changes to the Mineral Resource Estimates (effective February 2024) and reiterating the maiden Ore Reserve (effective March 2025). The estimates are compliant with JORC 2012 and NI 43-101 standards and are signed off by Competent/Qualified Persons.
Reasoning: Hot Chili Limited's annual Mineral Resources and Ore Reserves statement confirms previously reported estimates for the Costa Fuego Project, which are compliant with JORC 2012 and NI 43-101 standards and signed off by Competent/Qualified Persons. However, the effective dates for the MRE (February 2024) and ORE (March 2025) are somewhat stale, and the document explicitly states no material changes to the MRE, resulting in low novelty.
Positive factors
- JORC Compliant
- NI 43-101 Compliant
- QP/CP Signed
- Cut-off Disclosed
- Metal Equivalent Assumptions Disclosed
Negative factors
- Stale Estimate
- No material change to MRE

Classification and evidence
Resource Updateneutral
Revised estimate for an existing resource — compare to prior to assess progress.
Why it applies: The document is an 'ANNUAL MINERAL RESOURCES AND ORE RESERVES STATEMENT' for the Costa Fuego Project.
Evidence · text
“ANNUAL MINERAL RESOURCES AND ORE RESERVES STATEMENT”
JORC Compliantpositive
Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.
Why it applies: All Mineral Resource and Ore Reserve estimates are reported in accordance with the JORC 2012 standard.
Evidence · text
“All Mineral Resource and Ore Reserve estimates are reported in accordance with the JORC 2012 standard”
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: All Mineral Resource and Ore Reserve estimates are reported in accordance with the National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
Evidence · text
“National Instrument 43-101 – Standards of Disclosure for Mineral Projects”
QP/CP Signedpositive
Qualified Person (QP) or Competent Person (CP) named and signed off — a member of a recognized professional association (e.g., AusIMM, SME, AIG, P.Geo) with relevant experience.
Why it applies: The estimates are based on information and supporting documentation prepared and approved by competent persons, with specific QPs/CPs named for MRE and ORE.
Evidence · text
“prepared and approved by competent persons.”
Stale Estimatenegative
Effective date is >2 years old — data currency concern, may not reflect current geological understanding.
Why it applies: The Mineral Resource Estimates have an effective date of 26 February 2024, and the Ore Reserve Estimate has an effective date of 27 March 2025, while the announcement date is 29 September 2026.
Evidence · text
“The Costa Fuego Mineral Resource Statement as of 30 June 2026, with an effective date of 26 February 2024”
Cut-off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: The cut-off grades for Mineral Resources are clearly stated as +0.20% CuEq for open pit and +0.27% CuEq for underground.
Evidence · text
“Total Resource reported at +0.20% CuEq for open pit and +0.27% CuEq for underground.”
Metal Equivalent Assumptions Disclosedpositive · Story-specific tag
No canonical definition is currently available.
Why it applies: The formula for Copper Equivalent (CuEq) grades, including metal prices and recoveries, is provided in footnote 9 of Table 1.
Evidence · text
“Copper Equivalent (CuEq) grades are calculated based on the formula: CuEq% = ((Cu% × Cu price 1% per tonne × Cu_recovery) + (Mo ppm × Mo price per g/t × Mo_recovery) + (Au ppm × Au price per g/t × Au_recovery) + (Ag ppm × Ag price per g/t × Ag_recovery)) / (Cu price 1% per tonne × Cu recovery).”

Reasoning: This is a confirmed Indicated Open Pit Mineral Resource for copper at Alice, compliant with JORC and NI 43-101, with disclosed cut-off and metal equivalent assumptions. However, it is a restatement of a prior estimate with a stale effective date.
Positive factors
- JORC Compliant
- NI 43-101 Compliant
- QP/CP Signed
- Cut-off Disclosed
- Metal Equivalent Assumptions Disclosed

Indicated Resourcepositive
Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.
Why it applies: category is "indicated"
Cut-off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: cutoff_grade is stated
QP/CP Signedpositive
Qualified Person (QP) or Competent Person (CP) named and signed off — a member of a recognized professional association (e.g., AusIMM, SME, AIG, P.Geo) with relevant experience.
Why it applies: qp_signed is true
JORC Compliantpositive
Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.
Why it applies: reporting_standards includes jorc
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: reporting_standards includes ni_43_101
Stale Estimatenegative
Effective date is >2 years old — data currency concern, may not reflect current geological understanding.
Why it applies: effective date is 2.6 years before this release

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.
