It sounds like you have only $5000 in coverage from mold damage. Check with your agent to make sure you are reading the policy limits correctly. I know that most companies have started limiting coverage for mold issues, since it can be expensive to remediate.
Most mold is not deadly, and there are lots of kinds of mold that is black in color but is not deadly. If you have mold, you may need to have it tested to find out the best way to eliminate it.
