RE:RE:RE:Why this Cassiar Gold has a million-ounce head startI e-mailed their VP IR Shirley about this, and this is what she wrote:
“I spoke with David Rhys, our Chief Technical Advisor and foremost orogenic gold expert in the world who had walked the underground Bain, Cusac and Main portals at Cassiar South back in the late 2000s, and his comments were that the statement about water issues at Cassiar is false. He said that when you develop a mine for the first time, you will often hit areas such as faults that may be full of water but they would drain out after a week or two so you can gradually develop the mine. This is particularly the case at Cassiar South since all the workings are located on a mountain and naturally drain downwards. In the case of historical workings at the various veins that were previously mined, they are already fully drained. As you go down further to develop new workings, you may encounter some water from a new fault but they would again drain after a week. The benefit also is that the workings at higher levels have already been drained so you wouldn’t get as much water draining at the lower levels.
Cassiar actually had a mine engineer checking out the underground workings last week - he was able to walk several hundred metres into the old Bain and Cusac declines into the mountain and noted there was very little water influx. The rock conditions were also very good which is typical of mafic volcanic rocks – they tend to hold up quite well over time. Dave has been in underground mines all over the world and in BC and noted that the historical mines at Cassiar South are not that wet at all. Particularly when compared to other mines in BC that are located under glaciers – now those mines can be super wet.
It’s possible that the original poster might have spoken to a miner from back in the day that saw one of the faults drain. But ultimately after a week or two, the fault would drain out and would not be an issue and the development continuesI e-mailed their VP IR Shirley about this, and this is what she wrote:
