The Hillside Cu-Au Project, located within striking distance of Adelaide in South Australia was discovered in 2008-2009 and since then a Resource of 330Mt @ 0.8% Cu(eq) has been defined and 120Mt @0.77% Cu(eq) converted into Reserves. Rex Minerals completed a pre-feasibility study in October 2012 and are progressing with development of a 15Mtpa processing facility to produce a proposed 70,000 tonnes of Cu and 50,000oz of gold, along with a sweetener of 1.2Mtpa of magnetite. This will all be done for a C1 cash operating cost of US$1.2/lb Cu (Eq), which is very impressive.

Last week I attended a very interesting presentation by AMC Consultants chairman and past AusIMM president, Peter McCarthy on "Why feasibility studies fail!" (Link). Peter has been involved in running studies for over 40 years and has seen many different reasons for projects not achieving the targets set out in the original feasibility study.
Some of the key points of project failure were around the very human desire to see projects be developed, even when objectively they may be doomed to failure. A lack of communication between study teams, construction teams and eventually operations teams also led to plans from feasibility not being implemented on the proposed schedule and leading to difficulties later in the project cycle.
