RE: James West PICKS XAG!!"Xtierra (TSX.V:XAG) has to rank among the TSX Venture’s best kept secrets. With the advanced Bilboa silver-zinc-lead project in Zacatecas, Mexico in feasibility with a 140 million ounce silver equivalent resource,..."
With the numbers from the NI43101:
Resource Category Tonnage (T) Zinc (%) Lead (%) Copper (%) Silver (g/t)
Indicated Resources 9,680,000 2.43 2.09 0.21 59.40
Inferred Resources 4,040,000 1.43 1.55 0.18 53.64
i only come to roughly 18 million oz. of Silver indicated res.
Inferred roughly 40% of that, makes together 25 mio. oz. Silver.
How can the difference of 115 mio. oz. silver equivalent out of the Zin, Lead and Copper grades be calculated?
