I have been reading Agoracom since the migration occurred from SH. Thanks all, for the informative posts. I just joined and this is my first post on Agroacom.
Webgogs --I would like you to see if you can get any information on the following questions that have been worrying me. My questions center on (1) my concern that the BFS delay was associated with preliminary NPV figures that were less than desired and (2) my wish to generate information that allows a more realistic valuation model.
1. Does the higher grade at deeper depth cause a change in the design of the starter pit? If so, is this one of the causes for the delay? As well, what is the effect of a different starter pit upon both revenues and costs?
2. Are the projected capex costs still within the previous range? Is there going to be inflation in the capex associated with the longer timeline?
3. The July 2011 measured and Indicated mineral resource (at a 0.20% copper equivalent cut-off) totals 1.01 billion tonnes grading 0.27% copper, 0.017% molybdenum and 0.18g/t gold.The starter pit should access higher grades than those averages. For modelling purposes, what percentage increase should be applied to these figures to represent the grades that will come from the starter pit?
4.How much overburden must be removed before ore extraction takes place and how long will that take?
5. How long will it take to exhaust the ore in the starter pit?
6. Proposed mill sizes have been 120,000, 150,000 and 180,000 tpd. As this mill size increases, what are the likely increases in capex?
7.AMEC reported that silver grades within the deposit range between 1 g/t and 2 g/t.Would 1.5 g/t be a reasonable figure to use for modelling? As well, what is a reasonable recovery rate for silver?
8.The 2011 RE stated that Schaft has hard mineralized material, which, in turn, suggests that operating costs are sensitive to the cost of power and grinding media. What is the effect of access to NTL electricity on both Capex and Operating costs?
9.AMEC did the July 2011 resource estimate.Are Tetra Tech’s estimation methods similar or different? If different, in what way do they differ?
10.Who reads the CUU presentation that is in Chinese?
