Over 2 miles down!

We’ve now drilled to 3450m MD. That’s over 2 miles, a distance it’d take about 45 minutes to walk at an average pace. Or the equivalent of about 11 Shard buildings or Eiffel Towers stacked one on top of another!

Our journey this week has highlighted the beauty of the micro world. These perfectly formed quartz crystals are from a sample taken at 3275m MD – resembling a geode and amazing to see through the microscope. Many ‘vugs’ or cavities in the old mines were lined with crystals like these and we think they would have provided a beautiful distraction for the Cornish miners as they ate their pasties deep below ground.
