Project Fenix is a proposed redevelopment plan for McEwen Mining''s El Gallo Complex in Mexico. Through a new Preliminary Economic Assessment (PEA) published in 2018, Project Fenix evaluates the potential extension of production in the complex, based on a 2phased transformation of the processing from the El Gallo mine, innovative inpit tailings disposal, and sourcing from several deposits.
The first outcome of pit optimisation is to determine the ultimate pit that gives the highest possible undiscounted surplus between net revenue and total operating costs, without considering scheduling constraints or discounting. A nested pit shell analysis is then used to determine the discounted optimal pit.

and has reconfigured the open pit haulage network with an increase in the number of dumps. Therefore, new methods for dump design optimization are of the highest priority in mine planning management. This paper presents a methodology to model and optimize the design of a dump by minimizing the total haulage costs. The loca
Jul 11, 2017 · As open pit mining of a mineral deposit deepens, the cost of extraction may increase up to a threshold where transitioning to mining through underground methods is more profitable. This paper provides an approach to determine an optimal depth at which a mine should transition from open pit to underground mining, based on managing technical risk.
This thesis investigates the effects of equipment size selection on the economics of open pit mining. The work presented, illustrates the importance of considering equipment selection in the wider context of the entire mine. A methodology is presented for evaluating the various variables that are affected by equipment size, Equipment Size Sensitive Variables, (ESSV) that will aid the industry

existingequipment and lowering unit costs, the company was able to reduce the controllable cash cost by US$2.7b in the 2013 financial year. • To enhance higher return on investment (ROI) on incremental investment, BHP Billiton has increased competition for capital and is driving down project cost.
Long''s 2009 study also found that introducing the variables grade and capital cost played a factor in estimating production rate, however expected tonnage was the primary factor. Long did generate equations involving grade and capital cost for open pit, however the inputs for these equations were not clarified. Applicability
This article presents cost models for open pit mines, which takes into account cost uncertainty. In this paper, cost uncertainty is considered as cost of under production, and cost of over production.
The transition from open pit (OP) to underground (UG) methods requires a large capital cost for development and potential delays in production but can provide access to a large supply of reserves and subsequently extend a mine''s life. Additionally, an operating
Truck haulage is the most common form of materials transport in open pit mines. Trucks can be used to haul ore and waste out of the mine or they can be used to haul to an inpit crusher where ore and/or waste can be crushed and then conveyed out of the mine.
