The growth potential is definitely the most spectacular asset of Orbite, IMHO.
It looks to me as inexorable as the rising of the ocean levels.
Only bad management, patents contestations or a takeover would worry me.
If 2012 has been rather horizontal for the SP, consolidation of the fundamentals has been intense.
When one compares the 2012 chart with those of Molycorp, Lynas, Quest or Matamec, one likes horizontal.
I'm rather sure 2013 will not be horizontal though... :-)))
