| A 200 foot winze, i.e. an internal shaft, was established from the 500 ft. to the 700 ft. level with sub levels at 550, 600 and 700 ft. |
| Completed the detailed design of a new winze at the Grasberg complex, to be used for high-capacity muck haulage. |
| He was not prepared to get his feet wet and didn't like the dark, so he told us to sort it out and dump it down a flooded winze. |
| On hearing the noise they ran to this winze, and, looking down, saw the water boiling and roaring far below. |
| The company has decided to replace the old shaft and winze with a new 7,500-foot single lift. |
| Another winze disclosed pockets of gold mineralization, but no mining was done in the area because of fractured and altered ground and an influx of water. |
