You are correct - you will now have to wait on drill results to see if the conductor contains a deposit of nickel sulphide.
On the positive side - Sirius has a market value of near enough to $900M. Boadicea only has 45M shares on issue. If they were lucky enough to find an ore body of nickel the same size as Sirius' Nova and Bollinger ore bodies, it would be reasonable to assume that the share price could increase to $15.00 which would give them a market cap of say $675M. Allowance has to be made for the cash that Sirius holds and a few other matters.
Even if this conductor turned out to be barren, Boadicea still has a number of other conductors to explore on their lease.
As mentioned by a number of other posts to this site, this little company represents great value and has the most upside of any of the juniors exploring in this area.
