Workers not taking mined ores to stockpile

so I’m in need of some ores, so I made my workers mined some rocks. They mined it as usual but the problem is they only take like a handful of the mined ores, and just left the rest lying on the ground.

is there any manual way to make them take all those to the stockpile?

A screenshot I took about this issue --> Steam Community :: Screenshot :: al those precious ores lying around.....

if its fairly far away from your flag I would suggest either using the ‘loot’ option and highlight the items with it or set a crate or chest down nearby then once they fill that up move it closer to your stash pile
