Neues von der Silbersuche bei Freiberg – Lesenswerter Report über das „Silver City“ Projekt von Excellon Resources Inc.

Der aktuelle NI 43-101 Technical Report vom „Silver City“ Projekt der Firma Excellon Resources Inc. über die Silber-Suche bei Bräunsdorf in der Nähe von Freiberg wurde Ende 2021 veröffentlicht. Ein südafrikanischen Consultant hat im Auftrag von Excellon einen fast 100 seitigen Bericht erstellt. Darin sind u.a. die geplanten weiteren Prospektionsarbeiten enthalten:

  • „Step-out diamond drilling at Bräunsdorf to assess the extent and nature of mineralization below workings of the historical Neue Hoffnung Gottes Mine.
  • „Step-out diamond drilling at Grauer Wolf and Reichenbach to confirm the continuity of the known mineralization along the strike and towards depth.
  • „Step-out diamond drilling at Großvoigtsberg to confirm continuity of the known mineralization along the strike and towards depth, particularly in the areas where rich ore shoots were documented during historical mining.
  • „Drill testing of magnetic lineaments and inferred geological contacts near Grauer Wolf and Reichenbach.
  • Drill testing of magnetic lineaments and inferred geological contacts at Siegfried, which are interpreted to be an extension of the Bräunsdorf mineralization towards southwest.
  • Drill testing of magnetic lineaments and inferred geological contacts at Obergruna where historical mapping indicates the presence of mineralized veins.
  • Fence drilling at Langhennersdorf to test soil anomalies.
  • An airborne magnetic survey in selected areas to complement the dataset that was obtained during the earlier surveys.
  • Rock magnetic susceptibility study on available drill core for all target areas and all encountered lithologies to support the interpretation of available and future magnetic survey data.
  • Soil sampling calibration study with lines crossing known mineralization to test geochemical response.
  • Archive work, digitizing and georeferencing historical mine plans etc.
  • Regional exploration work on the rest of the Project.
