I think people in the main expect every new find to be a "SIR" find. The odds are very much against it. That doesn't mean that there are not bigger finds or lesser finds out there. BUX may have a find that's worth while.
We simply don't know yet.
Unfortunately if a company doesn't spit out a continuous news flow like SIR did, punters jump to all the wrong conclusions. SIR was lucky enough to have a resource where nearly every second day there was something to report.

BUX hit 3% Ni. That's rare. An ore body somewhere made that 3% Ni. It may be too small to be economical. It may be large enough to be economical. Our share price dropping hasn't answered that question. Not even the drillers can answer that question. Not even the next hole can answer that question.

Only a thorough investigation will suffice. Those who hold on may be rewarded for their patience.
