Noront has stated that they are going to be using directional drilling. There will be 1 borehole (hole 49 might be used). Someone posted this site yesterday and the technology will be something similar to this.

As for angled holes from the surface. Think of a right angle triangle and then you can use some basic math to get the length of the hole.
e.g. you want a depth of 1000m and an angle of 10 degrees.
tan(10)=?/1000
?=~176
176m being the length of the triangle's base.
Then using pythagoris.
1000^2+176^2=130976
sqrt(130976)=~1441m
So, the hole would be around 1441m long to get to a depth of 1000m with a 10 degree grading.
