We have performed several drilling campaigns in environmental and temporal context to obtain pristine, unweathered and continuous stratigrahic succession of Precambrian geobiological samples. Since 2004, effort has been focused on three time intervals of the Archean and Paleoproterozoic eons. These include:

The Early Archaean between 3.5 and 3.2 Ga, which is characterized by massive sulfate deposits of atmospheric origin and associated forms of thermophilic or photosynthetic life.

• Pilbara Drilling Project 2 (PDP2), 3.5 Ga old Dresser Formation Western Australia
• Barberton Barite Drilling Project (BBDP), 3.24 Ga Mapepe and Dresser Formation, South Africa

The period between 2.8 and 2.45 Ga, which predates the Great Oxygenation Event and is characterized by a variety of global anomalies that stand amongst the most dramatic in Earth’s history:

• Pilbara Drilling Project 1 (PDP1 ), 2.72 Ga old Tumbiana Formation, Western Australia
  

The early Paleoproteroic between 2.45 and 2.3 Ga, which marks the Great Oxygenation Event and associated first global glaciation (e.g., Huronian glaciations).

•  Turee Creek Drilling Project (TCDP), 2.45 to 2.2 Ga old Turee Creek Group of the Hamersley Basin Western Australia.
