Would this lens fit a Nikon D3000?

I found this lens for special order on Henrys.ca and it's the perfect lens for what I need. It's a Sigm OS 18-50mm F2.8-4.5 DC Nikon HSM. It didn't list what the mount was on the specs so I'm hoping someone out there knows!
Added (1). Sorry, Sigma… I forgot the A

Always listed in lens total name this says Nikon So this is a zoom from 15-50mm in coverage with Optical Stabilization… Nikon (mount) HSM is an internal High Speed Motor for auto focusing. Don't use Sigma lenses myself so unfamiliar with meaning of "DC"
Yes this will mount and work on the D3000

As above… Yes, it will work, and it will also autofocus on the D3000 as well. That is what the HSM designation tells you on a Sigma lens.
The DC designation means the camera is designed for crop sensor cameras, Nikon uses the designation DX to mean the same thing.
