More likely what we have at Windfall are quartz stringers with high grade or within it.... There are multiple areas that have been drilled with 1 oz/ tonne or better results... Drilling into a stringer will provide unusually high grade... There will not be a zone of several meters square with 50 oz / tonne grade... What is more likely is many intersections of high grade material, over broader areas.
These high grade stringers are difficult to prove up oz in.... SGR has the same type of mineralization.. and is just now geting respect in the market.
The only way to prove up tonage is to go underground and sample over broader areas. By doing so a better understanding of the structure and consistancy of the material can be done.
To hit a stringer of such grade is very encouraging. The underground drifts will allow more intense drilling , and combinded with the drifting will provide the understanding of the structure necessary for a resource estimate.
San Gold achieved excellent sucess drilling from underground in definition of their high grade at depth... This would have required hundreds of holes from surface to achieve the same understanding.
Windfall looks very good! JMHO
