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.
The two intruders made no attempt to enter the building; instead they targeted a large pen storing chemical agents alongside one wall. In less than a minute Pablo attached a second timed charge to a pallet of drums labeled SULFURIC ACID, then escaped into the darkness.
They made their way to a second extraction building a hundred yards away, taking their time as the timers counted down. At the rear of the building, Pablo found the valve for a main water line. Monitoring his watch until just before the detonations, he twisted the valve, shutting off water to the building.
A few seconds later, the propane tank ignited with a boom that reverberated off the nearby hills. Night turned into day as a fiery blue glow enveloped the landscape. The top portion of the tank blew off like an Atlas rocket, screaming into the sky before crashing into the nearby open-pit mine in a ball of flame. Burning shrapnel flew in all directions, peppering buildings, cars, and equipment within a hundred yards of the tank.
The debris was still falling when the second detonation launched a mountain of barrels filled with sulfuric acid into the first extraction facility. Screaming workers fled the interior as the projectiles shredded the ore-leaching vats, releasing a nasty soup of toxic chemicals. Smoke billowed as the doors were flung open and the occupants staggered out.
Juan and Pablo lay in a ditch near the second building, dodging bits of raining debris as they watched a nearby door. At the sound of the explosions, a few curious workers poked their heads outside to investigate. Seeing the smoke and flames from the extraction facility, they called inside to their coworkers, then sprinted to the other building to help. Pablo counted six people rush out before he rose and moved toward the door.
“Stay here and cover me.”
As he reached for the door handle, it twisted from the other side. He jumped back from the opening door as a woman in a lab coat burst out. Her eyes focused on the nearby smoke, she never noticed him behind the door as she nervously followed after her coworkers.
Pablo slipped through the door, stepping into a brightly lit bay filled with dozens more extraction tanks. He turned left and moved to the far end of the building, where large storage tanks lined the wall. He studied their labels, then approached one of the larger tanks. KEROSENE. He tore away a bleed hose from its base, then opened its brass drain valve. A torrent of the liquid flooded across the floor and filled the
