may not be a day trade, but you know the old saying - buy on rumour sell on fact.
THis rumour seems to have legs though otherwise Barry Fitzgerald would not have devoted his whole column to it - a possible big Cu (plus Ni-PGE) discovery by BHP in the Musgraves.
TKL, RDS, MTH (or its spinoff) are the nearology plays. TKL/RDS are the best of those as both are targeting similar stuff to what BHP is reported to have found and RDS in particular may have the early beginnings of a similar major find.
Wait till the WA guys start to read their morning papers.
