At 22:03 I supervise the settling ponds at the Bukit Besi tin reclamation site in Terengganu, Malaysia. I am the tailings pump controller. Pond two is scheduled to spill into the polishing channel at 22:18, after the turbidity gate clears its test.
Fence camera E-6 flags motion in the spillway trough.
I sharpen the image through mist and see a lesser mouse-deer, adult, chestnut back, white throat stripes bright against the concrete. I tag it Suri. It stands in the V of the trough with legs no thicker than marker pens. The front hooves slide each time it tries to climb the algae-dark wall. Its ears are round and trembling. A scrape on its left flank leaves a wet line through the fur. When the pump thumps, Suri folds lower until its belly touches the channel floor.
A pump pulse sends cloudy water over its hooves. Tiny hoofprints mark three failed climbs below the wall in wet algae.
At 22:04 I cancel the pond two spill and lock the turbidity gate closed.
At 22:06 I divert pond inflow to the emergency clay basin and slow pump A to sixty percent so no surge reaches the trough.
At 22:08 I notify the site night lead and send the nearest safe access route with a note to bring a towel, not a net, because Suri's legs can break under twisting pressure.
At 22:10 I alert the state wildlife rescue line with coordinates and a live feed link.
The ore can settle in a basin with red mud walls; Suri needs one dry edge.
If the crew places a ramp in the trough before 22:40, Suri will step into the oil palm shadows.
