Ann: RFR Completes Acquisition of San Finx Tin Tungsten Mine, page-8

So crunched the numbers and got a more palatable but rough reserve size.

For tungsten 6.1kg/t equates to 0.60% ore and Wolframite is generally 76% WO3 so we have 0.46%WO3.

Tin 14.91-8.91kg/t equates to 1.49-0.89% ore, Cassiterite is 78% Sn so 0.69-1.16% Sn.

So 8mt (I think) of ore for 0.69-1.16% Sn and 0.46%WO3, much higher grade than Santa Comba and very similar tonnage if my maths is right. Plus we have all the permits in place minus the deep water permit so not too shabby for a plan B.
