'Born leader' inspired miners to survive

The crew of Chilean miners was pinned nearly a half-mile underground by 700,000 tonnes of rock after what felt like an earthquake in the shaft above them, and had no real hope they'd ever be found. Luckily, though, the men had Luis Urzua.

Urzua, 54, was the shift commander at the time of the disaster, and used all his wits and his management skills to help his men stay calm and in control for the 17 harrowing days it took for rescuers to make their first contact with them.

It was no surprise, then, that Urzua was scheduled to be the last of the 33 miners to leave the San Jose gold and copper mine after 69 days of confinement.

"He is very protective of his people and obviously loves them," said Robinson Marquez, who once worked with Urzua in a nearby mine, Punta del Cobre. "He is going to make sure that all of his people are out" before he leaves himself, Marquez said.

Under Urzua's leadership, the men stretched an emergency food supply meant to last just 48 hours over 2½ weeks, taking tiny sips of milk and bites of tuna fish every other day.

They conserved use of their helmet lamps, their only source of light other than a handful of vehicles. They fired up a bulldozer to carve into a natural water deposit, but otherwise minimised using the vehicles that contaminated the available air.

"The way that they have rationed the food, just as they've performed throughout this crisis, is an example for all of us," Mining Minister Laurence Golborne said after he first spoke with the miners via an intercom rescuers had lowered through a bore hole.

"We heard them with such strength, such spirit, which is a reflection of what for them has been a gigantic fortitude and a very well-organized effort," Golborne said.

Urzua was the first to speak to Chilean President Sebastian Pinera and to urge him to not let him and his men down.

"Don't leave us alone," he implored the president.

In a recording of a conversation between officials and miners led by Urzua, they were heard singing Chile's national anthem with strong voices.

"He keeps everybody's spirits up and is so responsible - he's going to see this through to the end," said a neighbour. Angelica Vicencio, who has led a nightly vigil outside the miner's home in Copiapo, about 50km from the mine.

Marquez describes Urzua as a "calm, professional person," and a born leader.

"It is in his nature," Marquez said. "It is his gift."
