You ordinarily have to arrange buyers if you have a tungsten resource. The only things that worry me is the dirtiness of the feed and the cost of washing the feed and envi problems, defining the area of the resource. As usual mining is a problem that requires a constant effort towards a solution, generally called the start up period. You usually hide this stuff from the investors.

It is worth a shot. There are many veins in the area that contain high grade tungsten as well as high grade gold. In the past they were only worked for tungsten for a few years. Some of the veins ran 3% tungsten. The tails we could get in the area comprise about 6 million tons, but they were never tested for tungsten in that mode. They run about 0.04 OPT gold or $30.68. CDN by massive drilling. Byt metallurgical test, 65% is recoverable by flotation. I am not satisfied with the met tests as they show an unacceptably low concentration ratio, but there is much work to be done, as well as in the super gravity area, which did not see much competent testing. The low grade con could be cyanided at a nearby mill however, with profitable results perhaps. Some of the feeds are sulfidic, and others are free gold. Treatment has to be looked at, but regrinding and intense cyanidation by a Gecko type plant could be looked at.

I think the tails may run conservatively about 5 lbs tungsten over the whole area, but that is subject to investigation. 30 million lbs of tungsten and 240,000 ounces of gold at 50% recovery is worth about 304 million CDN. Max recovery cost would be about 60 million all up. Time to recover would be in the region of 7 years. Capex, graduated to fill tilt would be about 5 million. Gravity con operation may be startable for less than 2 million. If it worked. The extremely low capex compels one to spend some effort to see if it cannot be done.
