MegsterIf it's mainly the freeze ring factor, then that is an easy fix. Freezing is not an untried technology. Far from it.
The only unique thing about TAM is that their deposits are high grade and very compact (very unusual for a base metal deposit), allowing for cost effective freezing that would not be in the typical vein style base metal deposit.
And it's already been proven at Pine Point by Cominco, so there should be little doubt about it's effectiveness. I've talked to Layne Christenson. They don't have any concerns. Said it's bread and butter application and is an ideal solution.
If some are ignorant of the technology, that's management's problem for failing to educate the market. However, if you are skeptical of a proven technology, nothing but going out and proving it will ever convince those types of people.
