I forgot to mention that this first table that @GeoFiji put up is also pretty informative where he is attempting to show the variation in the AUD/Ton value of different deposits that CNB has. This may be a deciding factor on where to geographically construct a central sulfide mill or plant in the future and/or make decisions about which ore gets sent where for third-party treatment in the future (i.e. trucking costs and economics).



It's a good demonstration that his back-of-the-envelope $$/ton valuation metric explains why Kalman is still sitting out there unmined today - despite being discovered decades ago, and why other higher-value orebodies have been mined and in some cases depleted and closed while Kalman has sat there unloved. As many here would remember, I've always been a skeptic on the economics of Kalman and its weird and wonderful polymetallic nature and complex metallurgy. Although the smaller but higher grade "Kalman High-Grade Zone" on the face of it is an improvement over my initial impressions of the larger but lower grade Kalman resource, so I'm prepared to have an open mind about Kalman there and basic economics and economy of scale arguments along with orebody geometry help explain why that's the case and explain why things such as Starra, Osborne and Mt Isa and Ernest Henry are already being mined, and why other resources either need improved tonnages or grade to add value - hence why exploration and drilling exists.
