Would any of you kind TXN holders be able to compare for me- it's just a favour- the reserve upgrade of TXN versus the reserve upgrade of AMU, please? I had a look but got a bit confused. I am attempting to do a simple valuation, thinking that AMU is half the market cap of TXN, so does it have half the reserves? I'd be really grateful if any of you oilly types could do this, but no worries if you don't! Cheers.
