Hello Tau.
My understanding is that they are drilling from the 5700 foot level within the mine workings. I was unable to find which direction they are drilling. They have previously drilled upwards from the 2475 foot level creating cores of 200 feet in length. Therefore, I don't know if they are drilling up, down or sideways.
Someone with a good knowledge of dip and azimuth should be able to tell you the actual depth of this intersect.
