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.

Approximate tonnage and description of composite rock types from PCI. These input parameters do not reflect the final costs and recoveries tormocho the project but were used as the initial starting point for mine design.
These openings have provided PCI with access and information to identify the potential continuity of toromocjo mineralization below the limit of the old drill data from the down to the m elevation level underground.
Economic Input to Production Schedules.
Arsenic values are such that in-pit blending will keep arsenic heads sufficiently low that smelter penalties should not be an issue. The mineral concessions are held as an option agreement between MPCS and the Peruvian government mining entity called Centromin. IMC personnel have not visited a sample preparation facility that is as clean and well organized as the CIMM facilities.
In June more work was completed 10 holes along with a small test pit. The breccia texture crosses all rock types in the central portion of the deposit.
Sample intervals lengths for the PCI Holes are generally 1. Based on the flowsheet introduced in Figure 4.
The total model size and block size is summarized as follows: The presentation of equivalent copper on Table is intended to provide a general basis for understanding the combined economic benefit of processing copper, moly, and silver.
The concentrator, infrastructure and prefeasibility assembly were the responsibility of SNC. At the contact between the intrusions and the limestones, contact metamorphic skarns, tactites and hornfels have been formed. A listing of the chemicals used follows: Intervals torokocho Composite by IMC.

A review of the data summarized in Table The outer zone is propylitic with epidote, chorite, calcite, and sphene. More work is necessary to quantify molybdenum metallurgy. Execution of the items laid out in the option agreement will result in the go ahead for eventual production. Block and Bench Height. Within the PCI Holes, every interval was assayed for total copper and occasional additional metals.
The preceding logic was used by SNC-L to estimate molybdenum recovery of Basic statistics by rock type were completed on composites as well as nearest neighbor comparisons across rock type boundaries. These companies have mining concessions adjacent to the Toromocho Project.
The arithmetic average of the last three cycles of the locked cycle tests results in a decrease of final copper concentrate grade from However, some support analysis are not presented in detail but are summarized in order to streamline this text. IMC has not audited the proposed expenditure budgets provided by PCI and has not offered a professional opinion toromochl the reliability of future PCI budgets. The metallurgical holes selected by PCI for the test program are believed by the PCI geology staff to be representative of the flotation ore within the mine plan.
The floating cones were used as a guide to develop a series of 6 phase designs for the Toromocho Pit. Mill cutoff grades for the first 15 years of eoa mine life are above the breakeven value. A 9 km single circuit transmission line will be built from Pachachaca southeast of the project to the project site.
Toromocho mine – Wikipedia
Mine operating costs presented above are an average of all years of mining. This does not imply that the mine plan is inappropriate. Knight Piesold, Chile S. Inferred mineral resource is treated as waste within the Mineral Reserve mine plan and the pre-feasibility study. Figure illustrates the toromocgo and some of the infrastructure in the immediate area of Morococha and the surrounding area.
Figure provides a general overview of the project.
