Try doing high level Invasion missions against Corpus, specifically Survival and Defense. This nets around 200-300 per run, without Nekros. Mobile Defense is okay too but not as much.

Pros:
 * Oxium Ospreys spawn immediately and you don't have to wait for the first 4 waves like on Io, Jupiter.
 * You also get to earn battle pay.
 * You have a decent chance of finding an immediate 4 man group who might stick with you for 3 runs, depending on the quality of the pay.
 * Pretty sure Oxium Ospreys have increased spawn rate for Alerts and Invasions.

Cons:
 * Type of mission not always available
 * Type of mission changes
 * People are guaranteed to leave your public group after 3 runs.
 * Battle pay may not be worth it so not a lot of people running.
 * Corpus side may be offering something better

With a dedicated premade group for Oxium farming, some of these cons go away. I honestly prefer this method, as unreliable as it is, because Io is just boring with its same environment over and over, not to mention the Oxium Osprey spawn delay.
