SnapshotMuga-Vipasca is one of the most competitive potash projects globally. Muga is a unique project – with shallow mineralization with no aquifers above it there is no need to build a shaft. Muga is fully permitted: Environmental, mining concessions, and construction licenses obtained.

Mine production is planned over 2 phases. For the first few years and until construction of Phase 2, the Project will be selling only SMOP.

As of July 2024, Construction Progress is preliminary works at the mine gate and earthmoving. Key Construction Contracts (ramps and civil works) signed.

The Government of Navarra received a court ruling identifying a procedural error in granting the Goyo is one of the three Muga mining concession, where production is scheduled to begin after year six. The Company is in discussions with authorities for a resolution of the issue.

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.

Deposit has no aquifers and has shallow mineralization.
