Ann: Quarterly Activities/Appendix 5B Cash Flow Report, page-57

That $20 million is most likely attributable to further improvements like tailing's & dry stack ( hopefully , although no specific mention apart from their ECOLOGO® certification and ESG approval for the production facilities ) ....or whatever other June Qtr additional improvements to the Concentrator operations . And because if it were a deposit say for for Amos or something of the like ,it would have been reflected elsewhere in the cashflow statement under a different item.

I do like the theoretical Concentrate recoveries as a ratio to total ore mined for the quarter , and feel as though the Market will as well. Well on our way.
