Yes, sure, that's the goal. I mean, why would you go to a fab if not for mass production?

From the news release:

Mr. Peter Copetti, Executive Chairman Interim CEO concluded: "We now believe we have the right collaboration in place with Synopsys and our “3rd party foundry” to model our technology down to 40-nm and correlate our process to real physical device measurements. This should provide us with results needed to showcase our technology to potential customers at the optimum node for our platform."

"Real physical device measuments" means real production equipment, real mass production. To "showcase our technology to potential customers" (remember: customers = foundries) is not just presenting them a chip, but showing them the whole ecosystem needed to produce those chips. Imagine how excited these potential customers will be when POET can showcase them how they could produce superior chips on their old equipment!

This is really big! And while IBM spends money to get rid of an old fab, others will bring their fabs back to life and earn money with them!
