August

The data acquisition stage of the COGITO-MIN project took place from early August to late September 2016 in the vicinity of the Kylylahti Cu-Zn-Au mine in Polvijärvi, eastern Finland. Our Team members took part in all the components of the surface data acquisition, which consisted of:

  1. a novel 3D passive seismic interferometry experiment in which 1000 seismic receivers in a 3.5 x 3 km grid were left to record ambient noise sources for 4.5 weeks, with the aim to develop a cost-effective method for mapping the continuity of ore-bearing rock units in the initial stages of exploration targeting,
  2. two approximately 6- km long high-resolution seismic reflection 2D profiles tailored to accommodate full-waveform inversion for improved seismic velocity model building and exploration targeting,
  3. a seismic reflection 3D survey utilizing the passive seismic grid and a “random” distribution of active seismic sources.
