ore grade

IOCG deposits usually have large ore bodies range from around 10 million tonnes of contained ore to 4,000 million tonnes or more, and have a grade of 0.2% to 2% or more.

For example:
Olympic Dam, 8,330 million tonnes of ore at 0.8 % Cu, 280 ppm U3O8, 0.76g/t Au and 3.95 g/t Ag + 151 Mt at 1.0 g/t Au
Prominent Hill, South Australia: 152.8 Mt at 1.18 % Cu, 0.48 g/t Au, 2.92 g/t Ag + 38.3 Mt at 1.17 g/t Au

So, investors should compare to prominent hill IOCG and not sandfire's high grade VMS style copper gold discovery of average 3.5% or more, i.e. expect a large ore bodies intercepting decent grades.

High wave candle today shows market is uncertain with its direction. RSI down from overbought region, just need to hold tight for the result. If you do not believe in the assay results, you should have sold out earlier into strength.

Don't sell yourself short for holding such a high risk stocks if results turn out to be good. Bad luck if results doesn't excite market.
