Tough question to answer. Lots of people simply multiple the no of Resource oz x gold price which is unrealistic because all of the Resource oz will not be mined. Better way to assess value is looking at the NPV. With this in mind, take a look at the Scoping Study announcement but you should apply discounts to allow for the risks (basic level of study, lack of reserves/measured resources, ability to raise finance, etc):

The 240k oz of gold includes both inferred and indicated quantities. See JORC Resource table at bottom of most announcements. 80k oz is indicated and 160k oz is inferred. I would say the inferred material is "high quality" inferred. It is based on data from SOG and SBM who were meticulous with their resource drilling and estimates etc.

Hope this helps
