In recent days an abandoned pit was found in Sogo-ri, Chonma County, North Phyongan Province in the course of ore prospecting. Remains of 338 bodies and more than 300 relics were found in the pit 78 meters long, 2 meters high and 1.8 meters wide.

Mitsui and other Japs developed 46 gold and silver mines in Chonma area (Koryongsak-myon at that time) and looted more than one ton of gold and other natural resources every year by forcing Koreans to slave before the liberation of Korea.

Local inhabitants testified to the fact that Mitsui blew up the entries of some pits with rich ore deposit, leaving them buried, when the defeat of the Japanese imperialists was certain.

There was a lot of evidence proving the barbarous murder committed by Japs in the pit. They included skulls ridden with bullets, bullet-lodged femora, empty cartridges and blind bombs.

Unearthed there were rubber shoes, work shoes and dozens of sets of spoons and chopsticks, buckles with the Mitsui company trademark, wood cards of conscripted laborers, buttons, etc.

All evidence clearly proves that Japs shot to death the drafted workers, miners and even their families after throwing them into the pit in a bid to conceal the pits and left them buried.
