Hey Buddy,
Long time no hear, hope your doing well!
No idea about Amine, but Surpac is probably all that you would need for a small operation. It's been around for a long time with many places having their own customised TCL macros to do different things. There are a few third party software vendors, such as FlexiSurv that can get you up and running very quickly. Some of the Cons of Surpac is the package is losing traction to the likes of Deswick and Vulcan, the interface is outdated and it struggles with large data sets, in a nutshell it's a dying breed.
Deswick on the other hand, is relatively new, they have taken the best of the best from different packages including 12D from the civil sector, and are actively trying to put the best product on the market. It can quite easily handle large data sets including scanned point clouds. Making in house customisations are tricky however because Deswick wants to develop your ideas and place them as functions within the software. Mount Isa Mines (Copper) I believe to be the first in the country to take on board the Deswick MDM (Mining Data Management) system which is great for keeping one central data set, and essentially locks down file security to each user. The Deswick Scheduling module comes into its own for large organizations. Deswick is definitely the way of the future.
My advice to you, if your able to justify a higher cost, then Deswick is the way you should be proceeding. There is no point learning a new package that is on the way out...
