Analysis by Minestarters Atlas
Minestarters Atlas analysis
Summary
Probe Mines provided a metallurgical progress update for the Borden Gold project in Ontario, highlighting trade-off studies between two process routes. The results indicate that a whole ore leach (WOL) option may be superior and shows improved gold recovery curves compared to previous results.
Reasoning: The update provides progress on metallurgical trade-off studies, showing improved recovery curves compared to 2013 results, though specific recovery percentages are contained in an image rather than text.
Positive factors
- improvement over previous recovery curve
- encouraging results
- potential upside at higher grades
Negative factors
- results are subject to further analysis and PEA
Facts used in scoring: 2
Classification and evidence
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: The metallurgical program focuses on whole ore leach and flotation/regrind circuits.
Evidence · text
“gravity + whole ore leach ("WOL")”
Gravity Routeneutral
Gravity separation forms a material part of the flowsheet.
Why it applies: the document describes a gravity route ("gravity")
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.
