Deposit Type

  • Skarn

Summary:

ELG Deposits Gold mineralization at ELG occurs in association with a skarn body that was developed along a 2 km long corridor following the northeast contact of the ELG granodiorite stock. The skarn zone occurs at the marble stratigraphic level of the Morelos Formation is in contact with hornfelsed sedimentary rocks of the Mezcala Formation. At El Limón skarn mineralization is also structurally controlled by NE-SW and WNW-ESE trending faults and fractures zones. Skarn alteration and mineralization at ELG are fairly typical of calcic gold-skarn systems. Zones of coarse, massive, garnetdominant skarn appear within and along the stock margin, with fine-grained pyroxene-dominant skarn more common at greater distances from the contact with the stock. Significant gold mineralization at ELG is associated with the skarn, preferentially occurring in pyroxene-rich exoskarn but also hosted in garnet-rich endoskarn that has been affected by retrograde alteration. Pre and post mineralization dykes and sills are found to crosscut the hornfels and marble, along the structural trends mentioned above, and spatially associated with the skarn formation. El Limón Pit The main El Limón intrusion consists of an approximately peanut shaped stock of granodiorite composition, which is approximately 6 km long by 2.5 km wide and has a general elongation of N45W. Usually, the skarn is developed along the contacts with this stock, although the important bodies are controlled by major northwest and no ........

Mining Methods

  • Truck & Shovel / Loader
  • Drift & Fill
  • Mechanized Cut & Fill
  • Cemented backfill
  • Backfill

Summary:

Mining at the ELG Mine Complex is carried out by open pit method in the Guajes, El Limón and El Limón Sur pits and by underground mining methods for the ELG UG mine currently focused on the Sub-Sill and El Limón Deep zones.

ELG OP applies a conventional truck and shovel mining method. Open pit mining operations for the El Limón and Guajes pits are executed using the Owner’s open pit mining fleet and a contractor maintenance workforce, with some support of specialized contractor services. The El Limón Sur open pit operations are executed entirely by contractor workforce and equipment. All open pit operations are supported by owner’s supervision and Technical Services.

ELG UG consists of the El Limón and Sub-Sill deposits and applies cut and fill mining method with consolidated rockfill as backfill. Underground mining operations are executed using contractor workforce and equipment, supported by Owner’s supervision and its Technical Services.

Minimum Mining Width
A minimum mining width of 25 m has been considered in the pit and phase designs. This width must be respected to ensure a 91-tonne haul truck, with a turning radius of 10 m, can safely enter the mining area and make a 180° turn to be positioned for loading.

El Limón Pit Design
Mining in the El Limón pit is currently being done in the ED1, ED2 and ED2b phases. The pit floor in the ED1 phase is currently at the 1,141 m elevation and the bottom bench of the phase is ........
