Comparing PRU to NCM is like comparing a small dinghy to an ocean liner. PRU only has 3.5moz of reserves and 7moz of resources. NCM 52moz of reserves and 120moz of resources. At their current rate of mining PRU will run out in 7 years....NCM also has around 30% revenue from copper and climbing...no brainer buy and hold here. The last thing I want to do is invest in a small gold company that is mining too quickly relative to its reserves.
