Good'day Mr. Moore,
If you remember me some months ago we exchanged views
& ideas on geological mapping, You too tried to get a
contact on a job offer for me.
Now i have a question on drilling database, Most of
the historic drilling data would be in pdf format,how
do the mining sectors get it coverted into database
format. (may be in Microsoft ACCESS format).
The reason why i am asking this ? regarding drilling
database is, as the historic drilling data as the
survey, sample, lithology, assay & collar information
in plenty, separating these information needs
expertise
How is it beingdone any idea?
Regards,
Selvan
