Some resource research figures from Mineralised:
Lithium
Grade estimates range from 1.25% Li2O to 2.1% Li2O (the higher estimate is from the USGS)
Tonnage estimates range from 200 - 520MT, the tonnage estimates are using the known strike (5km + 5km) and depth (drill tested to 125m, which ended in mineralisation of increasing grade).
The spodumene crystals range from several centimetres in size to large metre long crystals, and are highly amenable to DMS recovery. No fine grain issues here.
Met testing has been done producing a concentrate grading 6%+ Li2O and at 80%+ rates of recovery, with very low iron content. This concentrate has also been successfully converted to lithium carbonate as part of prior feasibility studies done on producing carbonate on site at Manono in the 80s. This is all referenced and real.
Tin
Grade estimates range from 0.1% - 0.3%
Contained Tin estimates range from 200 - 350KT of Tin metal. This puts Manono as the 2nd largest undeveloped Tin deposit in the world.
Apart from its size the other unusual thing about this deposit is the ability to potentially produce Tin and Spodumene concentrate from the same ore, Tin is currently worth $20,000/T. Normally the grade you need for hard rock tin production is around 0.5% and over, but in this case as it will be part of co-production of spodumene and tantalum it looks like it could be economic. Lab tests have produced decent Tin recovery at 2mm crush size.
Tantalum
Tantalum is said to be uniformly found in a ratio of 10:1 to Tin, so 20 - 35MT of Ta at grades of 100 - 300ppm, similar to the best Ta bearing pegmatites we’ve seen. There’s supposed to be Niobium as well in a ratio of 1:2 with Tantalum
