"The real risk for now of course is that they don't have funding for the adit, which the article posted above would beg to differ with. "
Tachyon,
My back of envelope guesstimate of this cost will be somewhere between $2k and $4k per metre depending on rock conditions. The initial drive to the WRZ North high grade zone is 775 metres, suggesting a cost of between $1.55m and $3.1m. Ther will need to be higher roof chambers where the drill rigs will be placed, adding some expense.
A further branch tunnel to the BZ high grade zone will be of similar length, so double the above to access both zones.
Perhaps we have other posters who can be more accurate on the adit cost.
