Deposit type

  • Tailings

Summary:

The Magistral tailings deposit consists of the deposition of rejects from historical mill workings from the mid-1900s. These tailings were deposited within a natural low relief valley to the west of the historical mill and made up of relatively unconsolidated clay/silt particles. The provenance of the reject material was from treating gold bearing granodiorites and quartz veins. The primary sources were from the nearby mines: Colorados, Recompensa, Los Angeles, and Santa Ana. Thickness varies within the tailings up to 16 m.

The Magistral tailings is host to gold, copper and silver mineralization. The longest axes of the tailings deposit are approximately 550m north–south and approximately 575 m east–west.

A portion of the tailings, reportedly 750,000 tonnes, was removed from the deposit for secondary processing between 1992 and 1996. There are a few minor workings observed on the surface of the tailings deposit from artisanal miners (gambusinos), but these are not considered to have a significant impact on the estimated mineral resources.
