Summary

Nordic Resources Ltd announced strong metallurgical results for its Kopsa Gold-Copper Project in Finland, achieving up to 90% gold and 91% copper recoveries from a conventional flotation and leach flowsheet. Locked Cycle Tests and variability testing confirmed high recoveries and produced high-quality concentrates with low deleterious elements. These results will be integrated into an upcoming updated Mineral Resource Estimate for Kopsa.

Reasoning: The metallurgical test program confirmed high gold and copper recoveries from a conventional flotation and leach circuit, with clean concentrates and free-milling gold, significantly de-risking the Kopsa project. These new results will be integrated into an upcoming updated Mineral Resource Estimate.

Positive factors

  • High gold and copper recoveries achieved from conventional processing
  • Locked-cycle test work provides high confidence in results
  • Gold is free-milling, simplifying the flowsheet
  • Clean concentrates produced with low deleterious elements
  • Variability testing across different ore types shows consistent results

Negative factors

  • Modest arsenic penalty charges could apply to concentrates
  • Resource estimates are historical and awaiting an update

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 51

Classification and evidence

High Recoverypositive

Recovery at or above the exceptional band for the commodity and processing route.

Why it applies: Gold recoveries up to 90% and Copper recoveries up to 91% achieved from a conventional process flow sheet for the Kopsa deposit in Finland.

Evidence · text

“Gold recoveries up to 90% and Copper recoveries up to 91% achieved”

Pilot Scale Completepositive

Pilot or demonstration plant testing completed under continuous operation.

Why it applies: Locked Cycle and Variability Testing on eleven Kopsa samples confirm high recoveries for gold, copper and silver into high payability concentrates and doré using a combined flotation and leach circuit.

Evidence · text

“Locked Cycle and Variability Testing on eleven Kopsa samples confirm high recoveries”

Free Millingpositive

Simple, clean ore amenable to standard processing without oxidation.

Why it applies: The gold is consistently free milling, meaning no sulphide pre-oxidation steps are needed to achieve high recoveries.

Evidence · text

“The gold is consistently free milling, meaning no sulphide pre-oxidation steps are needed to achieve high recoveries.”

Multi-Domain Testedpositive

Variability across ore domains (oxide, transition, fresh) has been addressed.

Why it applies: Eleven samples in total were selected to represent all expected metallurgical response types.

Evidence · text

“Eleven samples in total were selected to represent all expected metallurgical response types.”

Deleterious Elements Presentnegative · Story-specific tag

Penalty elements (arsenic, antimony, etc.) or refractory concerns noted in the release.

Why it applies: Arsenic grades in the final concentrate were effectively managed through re-grinding of the rougher concentrate prior to the cleaning stages, resulting in average As grades of less than 1% in Stockwork concentrates and approximately 2% in Tonalite concentrates from locked-cycle testing. While these As levels could attract modest penalty charges, they are not expected to impact concentrate marketability which, thanks to the elevated gold and silver grades, should prove excellent.

While these As levels could attract modest penalty charges, they are not expected to impact concentrate marketability which, thanks to the elevated gold and silver grades, should prove excellent.”

JORC Compliantpositive

Resource estimate prepared in compliance with JORC Code (Australia) — high reporting standard.

Why it applies: The Kopsa gold-copper project is the largest and most advanced project and hosts a JORC (2012) compliant resource of 23.2Mt @ 1.09g/t AuEq for 814,800oz AuEq

Evidence · text

“JORC (2012) compliant resource”

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 information in this announcement that relates to the Kopsa Exploration Results and the MOGB Mineral Resources is based on information compiled by Dr Hannu Makkonen, a consultant to the Company.

Evidence · text

“The information in this announcement that relates to the Kopsa Exploration Results and the MOGB Mineral Resources is based on information compiled by Dr Hannu Makkonen, a consultant to the Company.”

Stale Estimatenegative

Effective date is >2 years old — data currency concern, may not reflect current geological understanding.

Why it applies: The Company intends to update the Kopsa resource in 2026 to incorporate the latest drilling and metallurgical results with an updated AuEq formula.

Evidence · text

“The Company intends to update the Kopsa resource in 2026”

Metal Equivalent Opaquenegative · Story-specific tag

Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used.

Why it applies: For Angesneva and Hirsikangas projects, AuEq grades are reported without disclosing the specific price, recovery, or payability assumptions used for their calculation, unlike Kopsa.

Evidence · table

“1.19”

Context: 3.85

Mill Routeneutral

Processing via mill or concentrator (CIL, CIP, tank leach, flotation).

Why it applies: the document describes a flotation route ("flotation")

Single Domain Onlynegative

Testing limited to one composite or domain — representativeness not established.

Why it applies: only one composite was tested

Reasoning: Expanded from assay table. 0.07 % copper is below against the default band [2.5, 1, 0.5, 0.25] %. Grade×width 0.6 %·m is below.

Negative factors

  • 0.07 % copper is below the weak threshold (0.25 %) on the default band.
  • Scored from rubric bands during table expansion, not from document context.

Reasoning: A good silver recovery of 82% was achieved from standard tonalite samples in a locked-cycle test, contributing positively to project economics.

Positive factors

  • Good recovery for silver
  • Locked-cycle test provides high confidence
  • Conventional flowsheet confirmed
  • Consistent results across different ore types

Negative factors

  • Modest arsenic penalty charges possible

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.
