SnapshotThe Company announced on 29 March 2023 that the Townhall of Sangüesa issued the licence for the construction of the process plant. This milestone was one of the Company’s highlight achievements of 2023 as this was the last construction licence required to begin the full-scale construction of Muga, comprising the civil works, the process plant and the ramps. To expedite the process, the Company requested an amendment to the licence; this amendment was to exclude a small parcel of public land that required a more extended licencing process. This does not impact the construction of the Muga process plant and has limited impact relative to the southern ponds.

Some preliminary works, which need to be carried out prior to the main construction have been progressed during 2023 year. Some of these works relate to earthmoving in preparation for the areas for the saline water deposit and the environmental protection barriers around the footprint of the Project. In addition, minor preliminary.

Deposit type

  • Evaporite

Summary:

The depositional basin bounds are defined to the south-west at the east-south east/west-north west trending Rocaforte Syncline near the margin of the Aragón River. To the north-west is the Sierra de Leyre anticlinal structure that overthrusts the Pamplona Marls Formation, the underlying unit of the evaporite. This thrust and two reverse faults run approximately east-west.

The first fault in the north is within the Pamplona Marls over Yesa turbidites. The second is coincident with the Liedena Sandstone, which overlays the evaporite. These faults are considered the extension of the Loiti Fault towards the east which also corresponds to the synsedimentary line between marine sediments within the Basin to the Eocene-Oligocene continental sediments at the thrust front.

The south boundary of the Exploration Target is an important fault running north-west/south-east that extends towards the east acting as limit to Magdalena anticline, considered the southern limit of southeastern section of the Muga Project area. In the west, the fault converges to the Loiti structure beyond the investigated area.
