Analysis by Minestarters Atlas
Minestarters Atlas analysis
Summary
Tintina Mines has completed its 2025 drilling campaign at the Domeyko Sulfuros Project in Chile, aimed at upgrading Inferred Resources and supporting an upcoming PEA. Preliminary metallurgical testing showed strong copper recoveries of 92.6% and favorable mineral liberation.
Reasoning: The announcement reports the completion of a drilling campaign and provides encouraging preliminary metallurgical results, though the full assay data for the new holes is not yet available.
Positive factors
- Successful completion of 2025 drilling campaign
- Favorable geometallurgical results (high Cu liberation, low pyrite)
- Strong copper recovery (92.6%) in rougher flotation
- Progress towards 2025 PEA
Negative factors
- Full assay results for the campaign are still pending (only 20% received)
Facts used in scoring: 2
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 a Qualified Person (QP) sign-off by Mr. José Luis Bello Soto.
Evidence · text
“The scientific and technical content of this news release has been reviewed and approved by Mr. José Luis Soto”
Free Millingpositive
Simple, clean ore amenable to standard processing without oxidation.
Why it applies: Mineralogical results indicate high chalcopyrite liberation and low pyrite association.
Evidence · text
“high liberation and low association with pyrite (Py)”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: Tests support the design of a conventional grinding circuit.
Evidence · text
“supporting the design of a conventional grinding circuit”
Single Domain Onlynegative
Testing limited to one composite or domain — representativeness not established.
Why it applies: only one composite was tested

Reasoning: 92.6% Cu recovery in flotation is a strong technical result.
Positive factors
- Recovery is in the exceptional band for copper flotation
Evidence · text
“five-stage kinetic tests yielded average recoveries of 92.6% Cu”
Tags used in scoring
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: processing_route matches the flotation signal
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: 92.6% is at or above the exceptional band (92%)

Reasoning: 74.9% Au recovery is a reasonable result for a flotation-based circuit.
Positive factors
- Solid gold recovery for a flotation circuit
Evidence · text
“74.9% Au at P80 = 150 µm”

Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: processing_route matches the flotation signal
Low Recoverynegative
Recovery below the weak band for the commodity and processing route.
Why it applies: 74.9% is below the weak band (80%)
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.
