The rate of drilling holes is dependent on how far the drill has to move, how difficult the move is, does a geologist have to be there for the set up, how deep do they have to case (e.g. how deep is the overburden), length of hole, down hole surveys (1-2 hours), are they cementing the holes (3-5 hours to fill the intercept part of the hole with cement to prevent springing a leak when they hit a drill hole while mining :), is the casing pulled or left in (save time), company policy for inspecting the end of hole before shutting down a drill hole (does a geologist have to be at the drill) etc.

The easiest move is no move at all.   You often see a couple holes where they are drilled from the same drill pad by just steepening the angle of the drill collar and drilling again.   Most of the time involved in moving the drill relates to prepping for the move and setting up on the new drill pad.  The next drill pad is prepped long before the move happens.  The actual moves happen fairly fast (a couple of hours) unless you have difficult terrain to deal with.   Usually the foreman and gophers will move everything the crew needs to the next site (including setting up water lines and pumps etc) before the actual shut down of the old hole.  That way the crew can start drilling again as soon as the drill is repositioned.   The foreman and gophers then go back to the old site and bring everything (drill rods, fuel, core boxes, etc) to the new site after the drill is moved.   The strategy for the drill company is to keep the rig turning as much as possible.

Casing a hole through the 10m of sandy overburden can be done in an hour or two.   Casing through boulder strewn overburden can take the better part of a shift.   Every hole will be different.

Drilling rates vary by how deep you are.   After the first few meters you get pretty consistent production through 250 meters.  After that it starts to slow down as every core pull takes longer and longer.   Everything that the drillers have to do at the hole other than drilling (shut down inspections, down hole surveys, cementing etc) slows the drill rate down.

We can ball park that an average move, setup and casing a hole will take about a shift.  So at 75m/shift (which is above average) drilling rates a 200 meter hole is roughly a shift to move and three to drill.  On these 4 shift holes they could do ~3 1/2 holes per week.
