Done Question Regarding Ender Quarry

I wanted to know how many chunks you can mine with the Ender Quarry? I heard from someone its 2 chunks maximum due to chunk loading, is this true ?

 

Its two chunks loaded at a time, the ender quarry itself and the chunk its currently mining in. You can mine any number of chunks, its not limited to 2.

 

Thank you very much for your answer.
