Yandal will be lucky to see deposits exceeding 1 Moz at probably 1-2g/t Au. More likely a few deposits in a range up to that though most will be 50K to 500K oz range with quite a bit of any resource requiring underground mining.
While not a very valid example one of the
lowest grade Au mines in the world is Paracatu in Brazil.[Link to Porter Geoscience data base on this deposit] Extract of resource section from that
Not a very valid example: open pit with free dig in the early years though may not be any more so comparing to bulk UG mining anywhere (and at Rogozna) is tongue in cheek.
However, it is not always about grade being king. Certainly helps. Rather, can a decent profit be made from the economies of scale that come from large lowish grade deposits. Many examples around the world show it is possible (Aitik, Copper Mountain are open pit and profitable)
IMO Medenovac may be the least likely of the four known deposits at Rogozna to make the cut for economics.
Likely to be large low grade and UG with more difficult metallurgy than Shanac/CC and perhaps Gradina. Love it or Hate it Rogozna is what current holders of STK have to consider. I hope by the end of this year results at Rogozna will be good and seen in a different way.
Yandal will need a lot of work to prove up mineable resources. It is the crowd favourite here on HC and will see that work done IMO if the results justify.
DD began 11/4/23
DD1/2 Palomino 23/5 and a week later the second batch of assays 30/5 announcement.
3 weeks have passed since the last announcement. Depends on the priority given to shipment and lab processing as to how representative the initial assays were. Fairly quick for DD IMO so they may have been expedited. Another batch of assays working their way through the lab for sure but pure speculation on possible on timing. Would hope for some more results by the EOFY 2024
About half way through the Fire Assay procedure. 50 fired samples being taken out of the furnace. Intricate, time consuming, process (fire assaying) with many steps still to go.
