# Copper smelters hungry for concentrate and Minrex has new ingredients Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/copper-smelters-hungry-for-concentrate-and-minrex-has-new-ingredients--a573e2fe-71fa-4f37-af89-8ae7c3c11528 Original source: https://stockhead.com.au/resources/copper-smelters-hungry-for-concentrate-and-minrex-has-new-ingredients/ Publisher: stockhead Original announcement: 2026-09-07T20:40:15.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Minrex Resources - Ticker: MRR - Exchange: Unavailable - Region: Serbia - Primary commodity: Gold - Secondary commodities: Silver - Document categories: Metallurgy, Drill results, Resource update - Extracted: 2026-09-12 00:57:16 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Minrex Resources is expanding its drilling program at the Tlamino project in Serbia to 9000m to support a JORC-compliant resource update. The company is also conducting metallurgical testwork led by Ausenco to optimize a high-sulphur gold-silver concentrate that targets current smelter demand. Reasoning: The company is advancing a significant drill and metallurgical program at Tlamino to convert a non-JORC resource to a JORC-compliant one and optimize concentrate specifications. - Positive factor: Expansion of drill program to 9000m - Positive factor: Metallurgical testwork underway with Ausenco - Positive factor: Historical flotation results showed high-sulphur gold-silver concentrate - Positive factor: Potential for high payabilities due to smelter demand for byproducts - Negative factor: Current resource is non-JORC - Negative factor: Historical PEA is six years out of date Facts used in scoring: 3 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The document mentions a metallurgical program led by Ausenco but does not explicitly detail specific QA/QC protocols like blanks or standards in this text. Evidence · text > metallurgical testwork program led by renowned engineering group Ausenco is also underway **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The program includes 3500m of infill and step-out diamond drilling at Barje. Evidence · text > It now involves 3500m of infill and step-out diamond drilling at Barje **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: the document describes a flotation route \("flotation"\) **Multi-Domain Tested** Polarity: positive Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed. Why it applies: 2 distinct composites were tested ## Extracted facts Stored fact records: 3. Some facts used in scoring do not have a stored record. ## Resource Estimates (1) ### Fact 1 [Link to this fact](https://atlas-extractions.minestarters.com/news/copper-smelters-hungry-for-concentrate-and-minrex-has-new-ingredients--a573e2fe-71fa-4f37-af89-8ae7c3c11528#fact-resource-facts-0) Tlamino · gold #### Identity - Project: Tlamino - Commodity: gold - Region: serbia - Reported Region: serbia - Ticker: MRR #### Resource scope - QP Signed: No #### Resource Data - Grade: 2.9 - Grade Unit: g/t #### Metal Equivalent - Metal Eq.

Confidence: medium #### Review - Needs Review: No - Historical: No #### Dates - Event date: 2026-09-07T00:00:00.000Z Reasoning: The 670,000oz gold equivalent resource is currently non-JORC compliant. - Negative factor: non-JORC resource Evidence · text > non-JORC resource totalling 670,000 ounces of contained gold equivalent grading 2.9g/t AuEq #### Tags used in scoring **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: no cutoff\_grade was stated **No Contained Metal** Polarity: negative Definition: Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting. Why it applies: contained\_metal was not reported **No QP/CP Disclosure** Polarity: negative Definition: No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience. Why it applies: no Qualified or Competent Person is named anywhere in the release **PEA-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study. Why it applies: the release names the study this estimate supports ## Metallurgical Results (2) ### flotation [Link to this fact](https://atlas-extractions.minestarters.com/news/copper-smelters-hungry-for-concentrate-and-minrex-has-new-ingredients--a573e2fe-71fa-4f37-af89-8ae7c3c11528#fact-metallurgical-facts-1) Tlamino · gold Historical result Needs review: historical\_restatement #### Identity - Project: Tlamino - Commodity: gold - Region: serbia - Reported Region: Serbia - Ticker: MRR #### Test Work - Program Status: preliminary - Test Type: flotation - Processing Route: flotation - Sample: historical flotation testwork \(2021 PEA\) #### Recovery - Recovery Basis: actual\_test #### Reagents - Reagent Notes: produced a clean, copper-free, high-sulphur gold-silver concentrate #### Review - Needs Review: Yes - Review Reason: historical\_restatement - Historical: Yes - Historical Source Date: 2021-01-01T00:00:00.000Z #### Dates - Event date: 2026-09-07T00:00:00.000Z Reasoning: Historical flotation testwork produced a concentrate with characteristics prized by modern smelters. - Positive factor: high-sulphur content - Positive factor: copper-free - Negative factor: historical data Evidence · text > Flotation testwork behind the 2021 PEA produced a clean, copper-free, high-sulphur gold-silver concentrate #### Tags used in scoring **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

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.
