Company webinar 1st June 2021 - Question 92 Jun 2021 09:48
My apologies, for sportsbilly is correct (thanks mate). In juggling things round to try to get them to fit in, I left out question 9. And it is an important one. Here it is:
9) The company has referred to the deep sulphides as “the ultimate prize”. Could you give an idea of the potential size of that resource and is it something that is a factor in funding discussions or is the open pit being treated as a standalone project?
Answer: The open pit is a standalone project. Funding the underground mine will be a different exercise in due course. The ultimate prize, well yes. Do not forget that we are drilling the sulphides this year. We know we are in a prolific geological district. We know that we are at the epicentre of 3 faults which cross at Empire. The largest US copper mine is at Bingham Canyon 4 hours down the road. We are absolutely in the right area, and we know we have a substantial ore body underground. How substantial? That’s anyone’s guess. “What I am about to say is not backed up or signed off, but is stated to give you an idea of the size.” We know from existing data that the sulphide belt is between 5-7 kms long (let’s call it 3 kms to be conservative), we know it is at least 1,000 ft deep (let’s call it 300 metres), we know it is 200 metres wide, at least. Multiplying these together, we have 180,000,000 cu metres of rock. This rock has a specific gravity of 3, but call it 2, so that is 360,000,000 tons of rock. As for grade, when the mine closed it was mining 6-8% copper, but let us call this 0.5%, (a very simplistic calculation) this gives us 1.8 million tons of copper. Ignoring all the other metals, although they are certainly there (like gold and silver). Putting that into perspective, the tenth largest copper mine in the world, The Grasberg mine in Indonesia, has 10 million tons of reserve, which suggests we are a world class copper deposit, and could be much larger. Looking at a 60% recovery rate, at today’s price, we have a deposit worth $11 billion just of copper, which shows how big this could be and that ignores the Tungsten/Molybdenum porphyry underneath (noting that Tungsten and Molybdenum are each approximately 3 times the price of copper). It could be pretty big. And worth getting out of bed for.
