Ann: Antimony exploration gains momentum at Windfall - Amended, page-3

This is new (as well as the table with sample locations):

"All are vein-type occurrences of quartz and stibnite1 (ranging between 20 – 60% Sb2S3) with breccia features commonly observed (Figure 2). The coarse-grained Stibnite comprises undeformed crystals with a massive, granular, radiating habit. The metallic lead-grey colour tarnishes to black on oxidised surfaces."

Does anyone know how much antimony is in stibnite (e.g., what could 20% stibnite mean in terms of antimony)? Historically, Munga Creek delivered grades up to 63% antinomy (note that the 20-60% mentioned above is stibnite, not antimony).
