Analysis by Minestarters Atlas
Minestarters Atlas analysis
Summary
Starcore reported Q2 2026 production results for the San Martin Mine, noting lower metal production and recovery rates. The decline was attributed to preg-robbing clay in the ore and carbon fines in the ADR process, which the company is addressing through plant optimization and new equipment installation.
Reasoning: Production results show a decline in gold and silver recovery and grade due to metallurgical challenges (preg-robbing clay and carbon fines), though management is implementing technical fixes.
Positive factors
- installation of filter presses to mitigate carbon fines
- optimization of CIL plant
- installation of cyanide destruction module
Negative factors
- lower metal production due to preg-robbing clay
- gold recovery decline
- silver recovery decline
- carbon fines issues in ADR process
Facts used in scoring: 2
Classification and evidence
Refractory Orenegative · Story-specific tag
Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk.
Why it applies: The company explicitly mentions 'preg-robbing' effect caused by clay, which traps gold and reduces recovery.
Evidence · text
“presence of clay in the ore, which caused what's known as a "preg-robbing" effect”
QA/QC Disclosedpositive · Story-specific tag
Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
Why it applies: The release names a Qualified Person (Salvador García) responsible for the technical information.
Evidence · text
“Salvador García, a director of the Company and Chief Operating Officer, is the Company's qualified person”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: the document describes a mill_cil route ("CIL")
Single Domain Onlynegative
Testing limited to one composite or domain — representativeness not established.
Why it applies: only one composite was tested

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.
