Sangdong numbers
Sangdong numbersMine size: at the 0.15% cutoff Sangdong would be in the top 3 tungsten mines in the world (4000-6000 tons/yr APT, at the 0.40% cutoff Sangdong would still be in the world top 7 and the largest tungsten mine outside China until Mactung or Sisson come up (these will require larger investments to get going).
Cost-wise: The 0.15% cutoff would imply CAPEX in the 150M range (from Tetra Tech). The 0.40% cutoff would imply CAPEX in the 100M range (my guess, based on size of equipment).
Ore processing should be similar in both cases at $60/ton (seems reasonable, but the information is missing at this time). Proven reserves at both cutoffs are now available including ore and grade.
The economics of the mine can be figured out based on these numbers and APT projected prices. In my opinion the approach to mine start-up that they seem to be taking is correct.
