The impairment charges I believe are an accounting requirement for public companies, must be booked because of the reduced Market Cap Vs asset value, lately due to change in gold price and cut off grade.
It's are a non cash expense and a reduction of asset value on the B/S.
Not sure when gold goes up, market cap up, and the cut off grades moves higher, then their property assets will be undervalued on the B/S, will they book a gain, I doubt it.
Most important for LSG and SGR, will they have the cash flow to pay all their expenses, exploration, development and other Cap X.
I believe LSG is in way better shape than SGR which is against the ropes for the next several quarters.
Also a lot of uncertainty now with SGR because of the secured debenture holder, what is their intent?
