“An old miners’ tale out of South Africa. I read about it while doing some research on diamonds. Apparently, there was a small weaving mill built near the turn of the century near Pretoria, South Africa. After operating for about a year, they started finding the mill workers going batty. It got so bad they had to close down the factory. The lunacy probably had something to do with the chemicals they used, but it never was clearly identified. It was later noted that the plant was built next to a platinum mine rich with ruthenium, and that ruthenium ore, which had little value back then, was stockpiled in great mounds next to the mill. At least one historian thought that the unusual mineral had something to do with the crazy behavior.”

“It’s an interesting story,” Pitt replied, recalling his discussion at the Co-op. “Have you by chance heard of any mining done by the Inuit up north in the old days?”

“Can’t say that I have. Of course, the Arctic is considered a mining candy land these days. Diamonds in the Northwest Territories, coal on Ellesmere Island, and of course oil and natural gas prospects all over the place.”

They were interrupted by a granite-faced Mountie, who poked his head in the door and asked Pitt to fill out a police report on his damaged rental car. The road construction crew arrived shortly after and went to work clearing a path through the debris. The loose rock and gravel was quickly pushed aside, and it was only a short while before a single lane of traffic was opened through the landslide area.

“Any chance I could bum a ride with you to the Elliot Lake airport?” Pitt asked the old prospector.

“I’m headed to the Sudbury region, so you’re pretty much on my way. Grab a seat up front,” he replied, taking a seat behind the wheel.

The big RV barely squeezed through the debris before finding open road on the far side of the landslide. The two men chatted about history and mining until the motor home pulled to a stop outside the tiny airport terminal.

“There you go, mister, ah . . .”

“Pitt. Dirk Pitt.”

“My name’s Clive Cussler. Happy trails to you, Mr. Pitt.”

Pitt shook the old prospector’s hand, then gave the dachshund a pat on the head, before climbing out of the RV.

“I’m obliged to you for your help,” Pitt said, looking at the prospector with a familiar sense of kinship. “Good luck in finding that beckoning mother lode.”
