Also a co. called Lodestone Mines as Clark has on his map, Olary Flats (https://www.lodestonemines.com) not public at present but have an experienced crew. Good explanation on their website of recoveries DTR DTC etc and the consequences thereof.

Production of 1 million tonne of concentrate from ore of DTR 28% or 21% versus DTR 14%
• At 28% 3.6 and at 21% 4.76 million tonne ore are mined and processed V’s 7.2 million tonne(50% more)
• If stripping ratio is 0.5 to 1, total rock mined is 5.4 or 7.2 V’s 10.8 million tonne (+3.6 milliontonne)
• If stripping ratio is 1.0 to 1, total rock mines is 7.2 or 9.52 V’s 14.4
• Higher DTR = Lower power & water usage = Lower Cost Operations
• Higher DTR = Lower total volumed mined = Lower Cost Operations
• Olary NE 12 orebody - DTR is 21.2%. Olary Creek ROM DTR will be 28%

HIO Mineral Resources Estimate is 12% to 13.7% DTR and has a DTR cut off of 6%,

HAV Grants deposit does not have a DTR, and not conclusive if it would have as it is not mainly magnetite and as such maybe not relevant but current grade stated for Grants deposit is 24% Fe (18% cut off at present for 304M Tonnes), no overburden, 8km from the rail line
That is not the Grants basin but logically/hopefully similar results would be achieved as it is adjacent, a single hole was drilled with a 488m intersection of 24.57% Fe so it looks quite consistent.
