Together with Block 122, the Company now has a 100% working interest in 3.2 million acres over the Iquitos Arch, the largest landholding on this trend.
The License Contract for Block 128 defines a seven-year exploration term divided into four periods, each involving a minimum work/financial commitment. The minimum commitment for the first work period, which is mandatory, is $0.5 million. The potential commitment over the seven-year period is $3.6 million and includes technical studies, seismic acquisition and the drilling of one exploration well. The License Contract defines an exploitation term of thirty years for commercial discoveries of oil.
Dana Coffield, President and Chief Executive Officer of Gran Tierra, stated, “This second transaction marks the completion of our exploration land acquisition in a significant new exploration play in Peru.
