SRU™ onsite in Western Australia
Date | August – September, 2013 |
Location | East Pilbara Western Australia, exploration drilling – coring |
Access / drill pads | Ample space, gravel access road. |
Drill hole information | Total depth - 1600m; PQ to 346m and NQ to end of hole |
Mud information | Mud circulated from the sumps (3 available) into a 2500L surface mixing tank and refreshed with approx. 2 x 1kg AMC AUSTROL, 1kg AMC EZEE PAC R™ and ½kg AMC CR 650™ |
Water | Supplied from two bores pumped directly to the sumps, but dependent on mill activities. The water condition was hard to very hard with elevated chlorides (approx. 800ppm as Cl), which affected mud properties |
Geology | Hard, yet unconsolidated. Burden pressure kept core intact but once relieved, collapsed into smaller pieces |
Mineral | Gold |
