a small junior mining company has found a reverse magnetic polarity anamoly in wawa, ontario canada, what are the chances for it to be a minable and economic deposit
The reverse polarity just means that whatever remnant magnatism left over in the rock from its formation has a polarity that is reverse of today's (it shows that what is now the north pole was the south pole at the time the rock formed). It does not take much magnetic material in the rock at all for it to be measurable by sensitive instruments, so the chances are slim that this indicates any significant mineral deposit.
