Argentine Brine Comparables, page-108

you can ask cxo’s former customers if this statement is true.

of course, the nature of brine changes over time and due to various factors. a natural process. perhaps also unnatural due to contamination during drilling or groundwater. i think you understand what i'm trying to say.

this also applies to hard rock. the grade from an mre/study is never constant over the life of the mine. in fact, past shipments of spodumene demonstrate that each shipment/batch has different grades. yes, what you see is what you get. this only applies to individual deliveries, just like brine. best regards to the geologist.
