Exploration activities were suspended on January 12 following an illegal protest by around 100 people.
The protestors threatened to enter the exploration camp unless it was evacuated and all work activities were immediately stopped.
Executive Project Director, Bryan Bailie, stressed that safety of its personnel is paramount and Wafi-Golpu Joint Venture will not put them at risk.
All non-essential personnel were evacuated as a precautionary measure.
He said after discussions with recognised landowner leaders, provincial and national government authorities with respect to the ongoing safety and security of staff and contractors, exploration activities recommenced as of 5pm Monday, January 21st.
Bryan stressed that WGJV does not tolerate behaviour by individuals or groups of people who threaten, make demands, or intimidate WGJV employees; activities that do great damage to investor confidence.
He acknowledged the cooperative support of the police, provincial administration, three SML Landowner groups, Mineral Resources Authority and other key stakeholders.
