02 · Verification

Data Verification

The applicable source release describes the data-verification, quality assurance and quality control, sampling and analytical procedures relevant to the reported results, together with any applicable limitations. Scientific and technical disclosure is subject to the Qualified Person review, approval and data-verification requirements applicable to that disclosure.

Website summaries should be read together with the applicable dated news release or technical report, which provides the complete scientific and technical disclosure.

03 · Reporting Basis

Technical Cautions

  • Spark is an exploration-stage company. No mineral resource or mineral reserve has been estimated for the Arapaima Project, and no economic analysis has been completed.
  • Reported drill intervals are length-weighted downhole intervals. True widths are not known and may differ materially.
  • TREO, MREO, NdPr, Ga₂O₃ and Sc₂O₃ values are in-situ analytical assay results. They do not imply recoverability, metallurgical recovery, equivalent-grade economics or economic viability.
  • Individual high-grade samples are not necessarily representative of surrounding material or mineralization elsewhere on the property.
  • References to a system, horizon, footprint, continuity, repeatability, zonation or deposit style reflect Spark’s current geological interpretation and have not been verified by a mineral resource estimate.

Forward-Looking Information

This website contains forward-looking statements and information involving known and unknown risks, uncertainties and other factors that may cause actual results to differ materially from those expressed or implied.
