excerpt from April 27 news release https://www.providencegold.com/news/anticipated-gold-values-found-in-stockpile-bulk-sampling-analysis/
As previously reported in the News Release dated February 24th, 2021, the Company commissioned FLSmidth to conduct standardized extended gravity recovery gold (EGRG) processing test work. This included two stages of progressive comminution and three stages of progressive gravity concentration using Knelson concentrators. Two composite batches utilizing 22 kg of material were produced using coarse assay rejects (-2 mm crush) from the 2019 sampling program.
The higher grade composite yielded a calculated head grade of 13.7 g/t Au. After simple crushing to -2 mm (P80 of 836 um), 49.7% of the gold was liberated and recoverable, and after second stage grinding to a P80 of 88 um 77.4% of the gold was liberated and recoverable.
The medium grade composite yielded a calculated head grade of 1.47 g/t Au. After simple crushing to -2 mm (P80 of 917 um), 35.9% of the gold was liberated and recoverable, and after second stage grinding to a P80 of 90 um 61.6% of the gold was liberated and recoverable.
so two compsites - one high grade - 77% recovery; one medium grade - 61% recovery
there is no low grade composite reject (ie. there were not 3 composites - but 2)
Yet, some here would have you believe this averages to 1g/t
given the two composites are of the same size, that's average 69.5% recovery, and 7.58 g/t average
or 5.2 g/t gold straight average
that's not bad for "free gold" - as it was described in the podcast
it is litterally sitting on the ground waiting to be scooped up with a back hoe, and run through a portable mill.....as their news releases and podcast clearly states.
and some here are saying....don't bother....it's not worth it....there's only 6 stockpiles, with the first being a conservative 25000 - yeah, that's only about $6 million from the first of the 6 stockpiles (assuming $1500 Gold)- why would we bother with that?
And for those doing DD, here is a copy of the 43-101 from 2018
