Perhaps the re-focus on mining is appropriate for this time when metals prices seem to be in recovery.
And, in speaking of metals prices, I noted that zinc prices were recently below what they were 25-years ago. Recovery here too is encouraging, but the future looks brighter for zinc than for other metals as this market is on the verge of dramatic shortages, or so I read.
The importance for us is in the fact that zinc is most often found/mined along with copper in Arizona.
