better than YRIYamanas' Chapada copper-gold deposit has measured and indicated resources of 421.4 million tonnes grading 0.31% Cu and 0.23 g/t Au (for a combined copper equivalent grade of 0.43% Cu) of which 310.5 million tonnes grading 0.34% Cu and 0.255 g/t Au (copper equivalent grade of 0.483% Cu), may be classified as reserves. This represents an estimated reserve of 2.3 billion lbs Cu and 2.5 million oz Au.
YRI is currently trading at over 3bucks and has more shares issued than MDR.
If you look at the Rio Grande numbers (and Lindero and Arizaro) they are more impressive than the Chapada deposit! We need some more drill holes (or promotion). I'm sure you could easily get over 500 tonnes at Rio Grande of 0.31% Cu!
