You're right, Garnfellow. It doesn't say. The spear description stated "it can be thrown" with no further detail. Personally, since a spear with a range increment of 20 feet can be used as a ranged weapon as well as a melee weapon (not an improvised weapon), I'd let them throw at the character's attack rate per round.
If we're talking about a longspear which is too bulky and heavy to throw (i.e., no range increment), then treat it as an improvised weapon and apply the abovementioned rule.
