MEM aprobó estudio de impacto ambiental de ToromochoLa Dirección General de Asuntos Ambientales Mineros (DGAAM) del Ministerio de En. While Chinalco had paid $ million for Toromocho, it expected to produce .. and Mines had to approve the EIA for an extractive project in Peru before. Gerald Wolfe pointed out that the company, which invested $ million in Toromocho last year, is waiting for the EIA approval to begin the construction phase.

From youngest to oldest, they are: It has been IMC experience that the total of the acid soluble and cyanide soluble assays are relatively stable over time. All tonnages reported in this document are in dry tonnes unless noted otherwise. A second large waste storage area is planned to be east of the mine. No effort was made with the new drilling to break the sample at geologic contacts. IMC holds the eiw that the allocation of material to the process plants would not change toromocuo with the increased metal prices.

The results for all check assay values are sound.

Property Location in Peru. All sizing units at CIMM are installed with a dust collection system.

Toromocho Project Technical Report dated March 22,

Intervals for Composite by IMC. Historic ore extraction from the underground mine northeast of Toromocho required the construction of crosscuts and drifts below and northeast of the Toromocho deposit down to about the m elevation. This zone, in turn, is eiia by a zone of lead-silver vein deposits.


The pre-feasibility study mine plan was based on a block model assembled in August of There are other holdings such as: MAG has appended to the report much work produced by others. The treated Kingsmill Tunnel waters consistently produce the highest copper grade final concentrates.

Those metal prices are higher than those used for development of the mine plan. The pulps are blended and split into 4 pulps of about grams each.

Toromocho mine

The distribution of chalcocite in the deposit is not typical for a porphyry copper. Every effort was made to maximize core recovery. The town of Morococha is eix typical of a small Andean mining camp. The heap leach process was not incorporated into the floating cone economic input. The corporate responsibilities for the prefeasibility study area summarize as follows: This report summarizes the resource, reserve, and prefeasibility status of the deposit based on all previous data combined with the most recent information from PCI and their contractors.

It tormocho been added to the reserve after evaluation of the economic benefit of its treatment. The first is the original easting to the nearest m, the second is the northing to the nearest m. The block flow diagram given in Figure Although the molybdenum grades and recoveries in the final copper concentrate appear to be markedly different for drinking water as apposed to the other water sources, they are similar in the first cycle and then begin to vary with the use of higher doses of CMC for the local water sources.


Heap leach recovery by year was modified by IMC to reflect inventory in pad and residual leach. Block and Bench Height. The deposit shows well developed concentric silicate alteration along with the metal zoning. There are however, some changes from the prefeasibility study as summarized below: Proper cleaning and maintenance of sample preparation equipment is practiced by the CIMM lab.

A large part of the population of the Morococha district works in the mining industry. Metal Prices, as basis for Schedule. These companies have mining concessions adjacent to the Toromocho Project.

PCI continued drilling through October of In the process, the mine delivers material to the following destinations: Approximate costs and recoveries were developed as eiaa to the floating cone. IMC understands that this is a titration process. However, the resource floating cone was not constrained by the national highway or by surface ownerships that PCI believes can be acquired in the future.

The core is transported to the PCI core logging facility at Tuctu.

This sequence has been intruded with multiple events. The impacts of zinc and arsenic on the process have also been investigated. The Low Grade Leach Stockpile is intrusive hosted material that could be leached or milled.

Mineral Resources in Addition to Reserves.
