Last quarter we sold 2,800 tonnes of iron ore and generated $100k. More revenues from waste materials as the management say is based on greater volume of sale. How much per tonne - your guess is as good as mine. 10,000 t for $100k or 100,000 t for $100k. Who knows?
We are hardly unlike to be given the unit price for these waste materials or even what type of waste material that the company is selling but wouldn't it be nice to see 200k or 300k of sales? That's still better than nothing from these waste materials. Our main focus is the iron ore.
