Pardon my ignorance & limited research but doesn't history show that SAS have achieved their goals to date , or am I missing something ? Next step, Pearls are in production , or is this incorrect ? Pearls are not in production ? I have been following SAS since the Diamonds went into production and thought everything was progressing to plan ? As my plan is to hold until the business is fully operational & generating the predicted revenue the current SP does not really concern me , sure I could have bought more at a cheaper price but my focus of attention is what the SP will be in 2020-2021 , if I want to I can just accumulate and average down. As long as SAS stick to their plan and keep progressing I can not see why SAS will not achieve their goals, I am sure SAS have all their bases covered ( including finance ) and believe they will get this business fully operational. All we can do is monitor their progress .
