Yes capex heavy at and near front, to develop the block cave, but helped by transitional open cut and especially by first quartile LOM opex, very important. Makes the project soundly cash flow positive, allowing owners to capitalise on key advantages of the location:
• Very good location for development: in desert near coast / infrastructure (power, seawater), hence relatively easy permitting then building.
• And in a now vg country jurisdiction.
• And large tenements in early stages of exploration, in a vg geological address (ie within major regional structural belt), esp along NW/SE corridor.
This combination of factors very rare in universe of global undeveloped large copper deposits.
And who knows where lies the long term copper price, now been high for over 6 years, and may stay high for long time to come? Given long term supply constraints (permitting constraints on many large undeveloped deposits, falling average industry grade, mines dying etc), and positive long term demand fuelled by sustained growth in countries with plus 3 billions of people (China in foothills of historic industrialisation, yes “structural problems”, but do not underestimate capacity to “reform”, a much brighter crew than Russia?)
