Ignacio Salazar , CEO of Highfield Resources-Geoalcali , stated that “we are delighted to close this agreement with Acciona, an important progress for the construction of Muga. This milestone represents a reactivation for the territories of Navarra and Aragon that surround the mine, localities “who have been suffering the effects of depopulation and who will benefit from the hundreds of jobs that the project will generate.”
The civil works are one of the three major construction projects planned by Geoalcali. Another of the planned works is the process plant that includes the construction of the warehouse, flotation plant, crystallization, drying, as well as truck loading, among others. The company already announced in March of this year, the awarding of the ramp work.
