The chromite petered out in a month and a half, and he was lucky to break even.

You should not assume that because you find an example of a native English speaker using bad pronunciation, or even bad grammar, that all native speakers do the same. In this case the speaker is saying 'he was' but:
1/ he is running the two words very closely together, and
2/ he is pronouncing 'was' as if it was pronounced closer to 'wiz', so it comes out sounding like:
Both of these are common habits among some native English speakers. If you listen to people speaking in your own language, I am sure that you will find a similar level of variation in how different people say the same sound.
