Jeez, these are some impressive results, including a truly bonanza grade silver intercept! Read on--
"New drilling tested further to the east, west and south of the existing resource (Fig. 3). The most important item, realized through the new drilling, is that extremely high silver grades are present. Hole CSX031 intersected some of the highest silver grades inside of the El Gallo Complex, returning 1,849 gpt silver over 10.5 m, which included 3,425 gpt silver over 5.4 m. The high grade appears to occur in a previously unknown steeply dipping structure, which may be a "feeder" to the previously defined flat-lying deposit. Further drilling, which is underway, will look to better target this style of mineralization. "
Just looked at Wolfram Alpha for a general conversion. There is about 1000kg/cubic meter of earth, roughly equal to one ton/cubic meter. We don't know how long the big vein is, but we're talking about $2700/cubic meter of silver in this vein.
