Another comparison via the Motley fool website:

Investors generally evaluate gold assets via their price per gold ounce. At $5.35 per share, Rubicon's $1.1 billion market capitalization, divided by its gold resources of 4 million ounces, equals $275 per gold ounce in the ground. I have excluded cash holdings, because they will go to mine construction and exploration. Still, having infrastructure already in place will lower the cost of building a mine. All told, with gold trading at $1,350 per ounce, this figure looks compelling on its own.

But it's even more compelling based on peer and transaction values. Another Canadian firm, Lake Shore Gold (PINK: LSGGF) has 2.5 million ounces of gold resources and is valued at $1.5 billion, or $600 per ounce. San Gold (PINK: SGRCF), with 2.6 million ounces, sells for $960 million, or $370 per ounce.
