Construction could be delayed on a billion dollar fertilizer plant in southeast Iowa after ancient artifacts were found on the site.
Orascom is building a $1.4 billion plant in Lee County.
The Quad City Times reports that Native American Artifacts including spear-heads, pottery and tools were found on the site. They are believed to be at least 1,000 years old.
Orascom could be forced to pay for a full excavation of the site before it would be allowed to build there.
