TECHNICAL DATA & LABORATORY ANALYSIS

Laboratory Analysis of SGH® Performance and Leach Residue

Explore laboratory-reported data covering two different aspects of gold processing: metallurgical recovery performance and solid leach residue characterization.

EcoGold presents laboratory analysis to support a more transparent and technically informed evaluation of SUPER GOLD HORSE® (SGH®). The available reports examine two distinct areas: gold recovery performance under controlled Carbon-in-Leach conditions and the analytical characterization of solid leach residues using the Toxicity Characteristic Leaching Procedure.

Each analysis should be interpreted according to its respective sample, methodology, analytical scope, and laboratory conditions.

TWO COMPLEMENTARY TECHNICAL PERSPECTIVES

Performance and Residue Require Different Evaluations

Gold recovery and residue characterization answer different technical questions. The metallurgical CIL test evaluates how much gold was recovered under controlled processing conditions. The TCLP analysis characterizes the reported concentrations of selected constituents extracted from submitted solid residue samples under a specified laboratory method.

Reading both analyses provides a broader technical perspective, while each report remains limited to its own purpose and test conditions.

Interpretation under specified TCLP conditions

The results characterize the submitted residue samples under the specified TCLP laboratory conditions. They should not be interpreted as representing every possible operating, disposal, or environmental condition.

RESPONSIBLE DATA INTERPRETATION

Understanding What Each Analysis Can—and Cannot—Conclude

Laboratory data is most useful when interpreted within the boundaries of the tested samples, analytical methods, and operating conditions. The results presented on EcoGold’s technical pages are intended to support evaluation and further discussion, not to replace site-specific metallurgical, environmental, engineering, or regulatory assessment.

Evidence within scope

What the Reports Provide

Information directly connected to the submitted samples, reported procedures, and specified laboratory conditions.

  • Measured Results

    Measured results for the submitted samples.

  • Defined Methodology

    Defined laboratory methods and procedures.

  • Controlled Comparison

    Comparative data under specified test conditions.

  • Recovery Measurements

    Metallurgical gold recovery measurements.

  • Residue Characterization

    TCLP constituent characterization of submitted residue samples.

  • Further Evaluation

    A technical basis for continued evaluation and discussion.

Read together with the applicable sample description, method, result tables, and report notes.

Interpretation boundaries

What the Reports Do Not Automatically Provide

Conclusions that require additional evidence, site-specific assessment, engineering review, or regulatory determination.

  • Universal Ore Performance

    Universal recovery performance for every ore body.

  • Commercial Guarantee

    A guarantee of equivalent commercial-scale results.

  • Complete Safety Assessment

    A complete worker-safety assessment.

  • Complete Impact Assessment

    A complete environmental-impact assessment.

  • Waste Classification

    A regulatory waste-classification decision.

  • Universal Pass or Fail

    A universal regulatory pass/fail conclusion.

  • Replacement for Site Testing

    A substitute for representative site-specific testing.

Broader conclusions should be supported by appropriate site, safety, environmental, engineering, and regulatory work.

Responsible technical communication: Transparency about test scope and interpretation boundaries strengthens the value of laboratory data for mining companies, consultants, engineers, and other technical readers.
