It's a rubbish resource because it is low grade and recovery rates are poor.

The company had over $19m of debt at June 30th last year - where do you get the idea they had little debt from?

"Could we not do a combination of selling off plant/equipment, and keep land & silver deposit, then fund remaining debt from shareholders?"

No. You can't do anything. Get used to that fact. The shareholders have failed, which is why it is in Receivership, and Administration. It has been taken out of your control. Neither R&M nor the Administrators will be interested in such a non-commercial idea. The plant and equipment is almost worthless in today's environment, the leach pads, liquor pool and liner are not removable and an abandoned silver mine with low grades and difficult to process ore is a liability, not an asset.
