Colombia's ELN rebels on Tuesday released a Canadian mining executive taken prisoner in January, the International Committee of the Red Cross said.

The guerrillas freed Gernot Wober, 47, in the northern province of Bolivar, the same region where they grabbed him in an Jan. 18 raid on a mining camp.

Wober, vice president of exploration for Braeval Mining Corporation, was handed over to a delegation including Red Cross personnel, the archbishop of Cali and the superior of the Jesuit order in Colombia, the ICRC said.

A doctor examined the former captive and found him in good health, ICRC Colombia representative Jordi Raich said.

"It makes us happy to know that he will soon be able to reconnect with his family," Raich said in a statement.

Wober was one of six people seized by the ELN in their raid on Braeval's Snow Mine project in a gold-rich region of Bolivar. The rebels released the other five captives in February.

The ELN, which has an estimated 1,500 fighters, said in April that they would only release Wober if Braeval relinquished its mining concessions in Bolivar

But the guerrillas ultimately dropped that demand and agreed to free the Canadian after Colombian President Juan Manuel Santos made it a condition for peace talks with the ELN.

Santos has been negotiating with Colombia's largest insurgency, the FARC, since last November, and the ELN has expressed interest in pursuing a similar process. EFE
