Some of the 2013 inferred was converted when Teck did some drilling at SC ages ago. That's the only way you can upgrade any significant amount. I'm expecting these resource numbers to be very close to the numbers booked by Teck and currently displayed on the CUU resources page. They are using the same resource model, project size and NSR cut-off. Some variation will occur because some aspects of the geomodel, such as variogram distance cut-offs, are interpretive. Still the variances would be expected to be on the order of 5% or less, whch is the case here if you add up the total M&I&I tonnages or metal content. I also don't expect much difference in the project economics between the PEA and Teck's internal estimates although we will never see what Teck came up with. You know, the results expected in November of 2019. Here are my numbers which I did as a quick check:
