In terms of drilling times - i got this from chat GPT. not sure how accurate:
WSBN drilled a hole (25RSDD001) that reached 777 m before pausing to get extra drill rods.
They encountered significant intervals of breccia / mineralization between ~520–777 m.
WSBN plans for holes to go to 1,000 m+ in their program.
They also plan to use double shifts (i.e. ~24-hour operation, split between crew shifts) for some of the deeper work.
⏱ Using WSBN’s rate to estimate for GEO
Given that WSBN reached 777 m for a diamond core hole in this program, we can approximate how long that took (or would take) and then scale up to 1,000 m.
If we assume:
Similar ground / geological difficulty (hard rock, etc.)
Similar rig performance and logistics
Then let's make a rough working assumption: to reach ~777 m depth took something on the order of 5-8 days of drilling, depending on interruptions, setup, etc. (this is based on how diamond core drilling tends to slow with depth, rig maintenance, rods, etc.).
Then to reach 1,000 m, you’d need an extra ~223 m past 777 m. Given that drilling tends to slow with depth (rod changes, core extraction more difficult, potential lower penetration rates), the extra might take proportionally more time. So:
First 777 m: ~5-8 days
Additional 223 m: maybe ~1.5-2.5 days, given increasing difficulty
If they use double shift operations, that could somewhat reduce calendar days (but not necessarily total drill hours).
✅ Estimate for GEO’s first drill based on WSBN
Putting that all together, for a 1,000 m diamond core hole under conditions like WSBN’s, GEO might expect ~6.5 to 11 days of actual drilling time, plus:
~1 day for setup / mobilization if already mostly in place
~1-2 days for logging, sampling, cleanup
So a full-to-completion timeline of around 8-13 calendar days seems reasonable, assuming things go well.
