RE:Raw Material to Concentrate RatioThe ratio of 150 tpd raw material fed into the ore-sorter to the 10 tpd silver produced has to do with the roughly 95% rejection-rate of the ore-sorter.
An 87% rejection rate was reported as early as 2017: https://bayhorsesilver.com/ore-sorting-results-establishes-2-5-ozt-cut-off-grade-silver-upgrade-of-275-rejects-86-mass/
And in this 3rd March 2020 news release, Bayhorse mention a 95% rejection-rate: https://stockhouse.com/news/press-releases/2020/03/03/bayhorse-silver-receives-ore-sorter-reject-assays-advises-exposure-to-gold-at
