Glencore plc. 50 % Indirect
On March 7, 2019, the Company announced that it had signed an integration agreement with Glencore plc (“Glencore”) and Newmont Corporation (then Goldcorp Inc.) (“Newmont”) pursuant to which the Agua Rica Project would be developed and operated using the existing infrastructure and facilities of Minera Alumbrera Limited (“Alumbrera”), which owns the Alumbrera Mine, in which the Company currently holds an indirect 12.5% interest with the other 50% and 37.5% interests being held by Glencore and Newmont, respectively.

Deposit Type

  • Porphyry


Summary:

The Bajo de la Alumbrera porphyry Cu-Au deposit, Argentina, is in the eastern Andes, near the north edge of a region of reverse fault-bound basement uplifts that overlie a low-angle segment of the subduction zone.

The deposit is centered on a closely spaced cluster of small felsic porphyry stocks and dikes, emplaced into andesites during seven phases of intrusion. Dikes of several phases define a radial pattern. Most of the porphyries are very similar to one another, with phenocrysts of plagioclase, hornblende, biotite, and quartz, in a matrix of fine grained quartz, K-feldspar, and minor plagioclase, biotite, and magnetite. Individual porphyries are distinguished mainly on the basis of intrusive contact relationships.

Highest Cu-Au grades are associated with abundant quartz veins, secondary K-feldspar, ±magnetite, ±biotite, ±anhydrite, in the earliest porphyry (P2), and adjacent andesite. P2-related mineralization is truncated by porphyries of the second phase of ore-related intrusions (Early P3 and Quartz-eye porphyry), which contain similar but generally less intense mineralization and alteration. Porphyries of the next phase (Late P3) truncate mineralization associated with earlier phases and are weakly mineralized with Cu-Au, sparse quartz veins, and secondary biotite. The still later Northwest porphyries truncate most Cu-Au, quartz veins, and potassic alteration, and themselves contain only traces of such mineralization and partially biotitized hornblende. Postmineral porphyries, the youngest, truncate all such mineralization and alteration, and none of their hornblende is biotitized. Los Amarillos porphyry and igneous breccia, along the western periphery of the porphyry cluster, is between P2 and Early P3 in age but shows little relationship to mineralization.

A low-grade core zone consists in large part of barren K-feldspar-magnetite alteration and quartz veins in Early P3 porphyry, and in part consists of later barren porphyry, so is mostly younger than the Cu-Au deposited with P2 porphyry.


Mining Methods

  • Sub-level caving


Summary:

Open pit mining completed in Q3 2018. [Glencore Annual Report 2019 P.74]

Standard truck and shovel mining techniques operations are employed in the open pit mine, utilizing 42 cubic metre shovels and 220 tonne haul trucks to move both ore and waste. Mining is carried out on 17-metre benches, with 2-metre sub-drill, which suit the size of the equipment necessary for the production rate.

Summary:

The original plant uses a conventional porphyry copper flotation circuit with proven, large scale equipment. The plant produces three products, a copper flotation concentrate containing the major gold credit; doré bullion fromgravity recovery of coarser free gold and, since July 2008, a molybdenumflotation concentrate.
