I could not give you this kind of information. It happens from time to time. Generally, it is not a serious problem. Recently, for example, water was spilled into Lake Snap from the local mine, which should not have happened. It is mainly a quality issue, a water turbidity issue, rather than a polluted water issue. In this case, we are talking of a diamond mine where no chemicals are used. The solution is to deal with the turbidity problem and to clean the water. That water was not up to standards before being spilled in the environment. So, we got involved and we are currently investigating.
