Ann: Lac Rainy Exploration Update, page-44

The jorc at Lac is much larger and contains much more and at better grades than expected so because the resource is LARGER and BETTER GRADE this number of drill holes needs to be larger and the roads need to be built because now there's more holes bigger project that would mean each extra hole is another helicopter job and it takes us longer using the helicopters and costs more . ANSWER this way is (a)a quicker method to employ than the heli and get to keep the roads as a bonus ,make no mistake READ the grades and remember the size is increased , the jorc is there so we have no problem laying down the roads and also even using them for additional exploration by channel mapping aswell.
This is a really really good announcement if you know what is at Lac
