Talking about Summer Project on Resume

Looking to potentially lateral from the my current bank for FT. I have had a couple good deals to talk about, but given the remote nature and shorter timeline of the internship I feel like my talking points aren't great. That said I've put in a ton of work and done quite a bit of the heavy lifting on the summer project we were assigned (thats purely internal) and was wondering if it would be worth it to also have that on my resume/ if other banks would even care. 

Thanks!
