He gazed across the dusty landscape to a conglomeration of glowing streetlamps. They marked the entrance to a large open-pit mining complex spread across the hills before him.

“Eduardo should nearly be in place opposite the guard station,” he said to a bearded man lying prone in a nearby sandy depression.

He was similarly clad in black, from combat boots to the thin stocking cap pulled low over his head. Sweat glistened off his face as he sipped from a water bottle.

“I wish he would hurry. There are rattlesnakes around here.”

His partner grinned in the dark. “Juan, that would be the least of our problems.”

A minute later, the handheld radio on his belt chirped with two static transmissions.

“That’s him. Let’s move.”

They arose and put on light backpacks. Lights from the mine buildings were sprinkled across the hillside in front of them, casting a pale glow over the barren desert. They hiked a short distance to a chain-link fence that encircled the complex. The taller man knelt and rummaged through his pack for a pair of wire cutters.

“Pablo, I think we can get through without cutting,” his partner whispered, then pointed to a dry wash that ran beneath the fence.

The sandy ground was soft in the middle of the creek bed, and he easily pushed some of it aside with his foot. Pablo joined him in scraping away the loose soil until they had excavated a small hole beneath the fence. Pushing their packs under it, they quickly shimmied through.

A low blend of rumbling noises filled the air, the mechanical bedlam of an open-pit mine that operated around the clock. The two men stayed clear of the guard station, to their right, and made their way up a gentle slope toward the mine itself. A ten-minute hike brought them to a cluster of aged buildings crisscrossed with large conveyor belts. A front-end loader at the far end was shoveling piles of ore onto one of the moving belts, which transported it to a hopper on stilts.

The two men were headed to a second cluster of buildings farther up the hill. The mine pit blocked their way, forcing them to cut through the operations area, where ore was crushed and milled. Clinging to the shadows, they darted along the perimeter, then worked their way along the back of a large storage building. Reaching an exposed area between buildings, they moved quickly, striding past a semiburied bunker to their left. Suddenly a door flung open at the center of the building ahead of them. The two men split up, Juan ducking to the side and scrambling behind the bunker while Pablo sprinted ahead toward the side of the building.

He didn’t make it.

A bright yellow beam snapped on, blinding him.

“Hold it right there or you’ll regret taking that next step,” said a low, gravely voice.

Pablo stopped in midstride. But as he made an exaggerated stop, he deftly withdrew a mini automatic pistol from his left hip and concealed it in the palm of his gloved hand.

The overweight security guard walked slowly toward him, keeping his flashlight pointed into Pablo’s eyes. The guard could see the intruder was a large, well-proportioned man, over six feet tall. His coffee-colored skin was smooth and pliant, in contrast to black eyes that burned with malignant intensity. A lighter band of flesh crossed his chin and left jaw, the souvenir from an ancient knife fight.

The guard saw enough to know he wasn’t an accidental trespasser and stopped a healthy distance away, clutching a .357 Magnum.

“How about you put your hands on your head and then you can tell me where your friend went.”

The rumble of a nearby conveyor drowned out Juan’s footsteps as he sprinted from the bunker and plunged a knife into the guard’s kidney. Shock registered on the guard’s face momentarily before his whole body tensed. A wayward shot erupted from his revolver, whistling high over Pablo’s head. Then the guard fell, his body kicking up a swirl of dust as it struck the ground.

Pablo thrust his gun forward, expecting additional guards to rush to the scene, but none came. The gunshot had been lost amid the rumbling of conveyor belts and the pounding of the rockcrusher. A quick radio call to Eduardo confirmed there was no activity at the front gate. No one else in the facility had realized their presence.

Juan wiped his knife clean on the shirt of the dead man. “How did he spot us?”

Pablo glanced toward the bunker. For the first time, he noticed a red-and-white sign on the door proclaiming DANGER: EXPLOSIVE MATERIALS. “That bunker houses explosives. It must be under surveillance.”

Blind luck, he cursed to himself. The explosives bunker wasn’t marked on his map. Now their whole operation was jeopardized.

“Should we blow it?” Juan asked.

They had been ordered to disrupt the facility but to make it look accidental. That had suddenly become a tall order. The bunker explosives could be made useful, but it was too far from their actual target.

“Let it be.”

“Do we leave the guard here?” Juan asked.

Pablo shook his head. He unbuckled the guard’s holster, then pulled off the man’s shoes. He searched the guard’s pockets and retrieved his wallet and half a pack of cigarettes. He stuffed those, along with the .357 Magnum, into his backpack. A growing pool of blood was dampening the ground around his feet. He kicked some loose sand over the blood, then grasped one of the guard’s arms. Juan grabbed the other, and they dragged the body into the darkness.

Thirty yards away, they reached an elevated conveyor on which melon-sized chunks of ore whirled by. With a labored heave, the men swung the guard’s body onto the moving belt. Pablo watched as the guard was carried up the conveyor and deposited into a large metal hopper.

The ore, a mixed fluorocarbonate known as bastnasite, had already passed through an initial crusher and sorter. The guard’s body joined a second round of pulverization that smashed the ore to baseball-sized pieces. A tertiary crushing repeated the process, pounding the rocks into a fine gravel. Had anyone examined the rough brown powder that accumulated off the final conveyor, they would have noticed an odd red tint that marked the guard’s last remains.

Though the crushing and milling were important stages in the mine’s operations, they were less critical than the secondary complex up the hill. Pablo eyed the lights of several buildings in the distance, where the milled ore was leached and separated into a handful of mineral components. Spotting no moving vehicles in the area, he and Juan took off at a quick clip.

The men had to skirt the eastern edge of the open pit, jumping into a culvert when a dump truck rumbled by. A short time later, Eduardo alerted them that a security guard was making the rounds in a pickup truck. They ducked behind a mound of tailings, then lay frozen for nearly twenty minutes until the truck returned to the front gate.

They moved toward the two largest buildings in the upper complex, then veered right and approached a small shack that fronted a towering propane tank. Juan took the wire cutters and snipped an opening in the surrounding chain-link fence. Pablo slipped through, circled the big tank, and knelt before its fill valve. Removing a small plastic explosives charge from his backpack, he attached a detonator cap and placed it beneath the valve. He set the digital timer for twenty minutes, activated it, and scurried back through the fence.

On the ground a few feet away, Pablo scattered the guard’s shoes, gun, and holster. The wallet came next, still containing its cash, then the rumpled pack of cigarettes. It was a long shot, but a superficial investigation might finger the guard for accidentally igniting a leaky tank—then being vaporized by the blast.

The two men scurried toward the next building, a large metal structure containing dozens of mechanized vats filled with leaching solutions. A small group of graveyard shift laborers monitored the vats.
