According to Thesaurus.com -
http://www.thesaurus.com/browse/research?s=t - "Research" and "Exploration" mean the same thing. Therefore, (mineral) exploration is
technically (mineral) research. The fact that minerals are being researched is irrelevant.
Anyway, wouldn't it be integral for the survival of
every mining company in the world (not to mention a core part of their strategy), to perform
some sort of research and development in order to be able to explore and drill in the first place? I'm sure they don't just go, "Right, I've got a shovel, now let's look over here!" They would have to
research where they're going to explore and
develop ways and means of being able to find
what they're looking for, wouldn't you think?
I doubt that there'd be many mining companies that
don't utilize R&D grants...
