- OGX reports from 2017

say 0.2 g/t going to tails but backhoe-sampled tailings grade was about 10 g/t. Were the tailings samples from OGX processing or earlier garimpeiro work? After all OGX hasn't treated 30,000t of ore.
- Why, if the tailings are running 10g/t, don't they stick it in a truck and feed it through HM3 or the old plant at a slower throughput? 30,000 birds in the hand are worth a heap of underground samples!
- The HM3 setup looks questionable. How is ore fed? It's going to take a lot of water to wash ore through at 25 tonnes per hour. Does it have to be pre-crushed to a particular size? After it runs off the sluice (and out of picture) where does the hammered ore go? Is it linked in with the old plant or stand-alone?
- Roughly how many tonnes of ore have been defined and at what grade since work started under new management? What are the cut-off grades for development and stope ore?
