Rescue workers are working against the clock to reach at least 15 miners trapped in a flooded gold mine in northwestern Colombia since Wednesday.<br /><br /> It is believed a power outage or an explosion could have triggered the flood.<br /><br /> The mine’s owner said many managed to escape, although he feared those trapped may not have survived.<br /><br /> One of the survivors spoke of his lucky escape saying, “I survived because it wasn’t my day to die… I was the last one to make it out. I was climbing with a friend from the hole grabbing at poles. My friend didn’t make it because when the mine filled up it fills up with gas and the gas drugs you.”<br /><br /> It will be an anxious wait for the relatives of the trapped miners, as authorities said it could take three days to clear the mine.
