From the pools I operate I would say that you can mine 100-200ACM a day. But this is only a rough estimation.

It also depends on the hardware you use and the current difficulty.

There are three pools controlled by the project and also several others you can find in this thread:

for fast miners & NiceHash: https://goldmine.actinium.org/
for "medium" miners: http://fastpool.actinium.org
for slower miners: http://pool.actinium.org
