As first reported by state-run news outlet Yonhap, eight of the missing crew are South Korean nationals and the other 14 are Filipinos.
A member of the ship's crew reportedly sent a text message distress signal to operator Polaris Shipping last Friday saying the vessel had begun taking on water on the port side, according to American Shipper.
"A search operation is continuing for the 22 people," a ministry official in Seoul said, adding that South Korea has requested aid from Brazil and Uruguay in the search and rescue efforts, according to a report from Reuters news service.
Reports from Yonhap over the weekend indicated that two of the crew may have been found in a life raft, but the identities of the rescued sailors has yet to be confirmed.
The 266,141-deadweight tonne Stellar Daisy was en route from Brazil to China with a shipment of iron ore when the distress signal was sent.
