Did a 30 gram assay today got a 1.4grain bead witch end up being a
gram 1/2 to the pound at least in my bag. think I should win the 4 free lbs. what do you think?
is that 1.5 grams per pound or .5 gram per pound
Ether way I would have to say your assay is not a true "representive" assay of a per ton or per pound expected yeald
1.5 gr = 3000 gr per ton or 96.46 ozt per ton
.5 gr = 1000 gr per ton or 32.15 ozt per ton
What did you do --- hand pick 30 grams of ore that had naked eye visible gold & run that as your assay --- if so (& thats what it looks like to me) then your assay does not come close to being a true assay
To get a true assay you need to crush at least 2 lbs ore to at least 100mesh (200 mesh would be better 800 -1000 mesh prefered)
dry mix it very well (in a tumbler) then run three to five 29.16 gram samples of this crushed ore as assay's & average the yeald of those samples to get a per ton (or per pound) representation
I spent some time in Northern California hard rock mining - the ore we were processing ran as low as 2 ozt/ton & as high as 6 ozt/ton
I have crushed & paned about 2.5 lb of Sean's ore & based on what I am seeing in my pan & would say its safe to say this ore is running at least 7 or 8 ozt/ton & maybe as high as 12 ozt/ton with an average of 8 -10 ozt/ton
keep in mind this is ore so it will very - some times by a lot --- thats why hard rock mines run multiple assay's & often assay's on their ore
one assay wont represent THE ore & an assay of hand picked ore is a lie
