Question on Silver SandFollow

I am now a lvl40 miner and i find that on Grade 5 nodes i dont get Silver Sand anymore. Wether i go to Treespeak or Halathali or Iron lake i litterally get 0. Giving that im getting Gold Sand from the Grade 5 its kinda lame that we dont get silver sand anymore so to make the Electrum Nuggets.

So i said to myself Fine! ill go back to Grade 4 nodes where i got Lots of silver sand in the past! So i settle near Humblehearth and start mining at the silver sand sweetspot (which is +3 btw for thoe who didnt knew) But to my great surprize (and almost horror) i dont get Silver Sand anymore there either ...... is it because when you get in the high 30s (like 38+) you dont get to mine Silver Sand anymore? that would be very lame if i cant ever get any anymore. Anyone know?

i had no problem when I went back there for silver sand, but you do get alot more garnets since that is the same sweet spot of +3

Thank everyone for the answers.maybe i was just impatient or very unlucky. I went back to Humblehearth today to see if i could get some sand and during the Leve "Mining Humblehearth" i got some silver sand. Afterwards the normal non-leve nodes started giving me some. But now i get way less than i used to when i was in the 20s and 30s. I guess that could make some sense since im now in the high end stretch for mining (the 40s). Ill now store all the silver sand i get since i am now getting much less.

i think you probably think you get less because you are going for silver sand rather than just getting it, also when you were 20/30 the stack sizes probably had not changed yet so it appeared you have more when you had multiple stacks of silver sand clogging up your inventory. Or the fact that now you will get more garnets up as I said earlier than earlier levels.
