Thank you, Mr. Speaker. My understanding is there are quite a number of options that are out there. The option that is being pursued now is seen as the best, most immediate option. There are bacteria that eat arsenic that have been used in other processes to recover a mine. There are also some other approaches that are more expensive such as finding a way to get rid of the arsenic. One of the recommendations was to haul it away. So there are a number of options, but the option that is being pursued now that is being undertaken is the most immediate and will have the best way to control the problem. Thank you, Mr. Speaker.
