good to hear youall are doing better, those breakdowns suck, you may not need a bigger crusher? just perfect your sampling method and run only paying rocks.
Do all your sampling by hand so you do not to contaminate the sample, you can do it right at the dig site while your are digging, then you have a better idea where your values are in the vein, I don't know if this your method but it works well for me, save a lot of time.
I see your are working the big veins, and was wondering in your values do they run through out the vein or are they just in the vuggy colored zones.
if its just the vuggys paying, only run that material as its a little softer than the solid quartz, sometimes I find on these big quartz veins that only one part of it pays I call it a sliver vein..
it is common for it to be on the contact with the country rock, or near that zone. and common to be vuggy like your pics.
Keep it up you might hit a full blown pocket, good luck.........
From your pics, looks like you have one of these sliver veins ? that's why the old timers left it, chasing a sliver of pay through a vein the size you have there, is it a pain in the butt, and rarely do they produce a sizable pocket.
Good luck....................
