Central reports Palm Valley-12 at 2,278m on 27 June, 220m in the week, with gas shows from 1,778-2,278m. Its CEO says drilling has been difficult, behind schedule and over budget. The JV will consider a horizontal lateral to appraise P3.
NZOG relays Central's update: Palm Valley-12 drilled 220m in a week to 2,278m in the P4 unit. Gas shows through 1,778-2,278m and minor gas flows suggest no significant fractures in the P3. Arumbera target still 3,560m; Cue holds 15%.
