Noche  Buena  was  purchased  from Seabridge  and opened  as  an open pit  in ’12. Here’s  historic  drill grades.  Should be  a lot more info now is  producing. I’ve  seen some  in   Fresnillo financials but this  was  easy to find.

“The Noche Buena project is located in northwestern Sonora State, about 55 km from the city of Caborca and within the geological terrain that is host to several large gold deposits, including the La Herradura and Mesquite Mines. Seabridge Gold purchased the property in April of 2006 and completed a NI 43-101 compliant technical report (news release dated April 28, 2006) that confirmed a resource (at a cut off grade of 0.30 grams of gold per tonne) of 21.9 million tonnes of indicated resources grading 0.81 grams of gold per tonne (569,000 ounces)”

Checking  our  Mexico Properties  site  just  the  6 vein portion BELOW open Julio 2  shaft ( .5  to 5.5  oz/ton)  contains  4 million tons  graded   2.5 g. or  1/3 million oz.  Veins  run  way above  the  shaft  as well to the  hill top and  shear  zone  and  quartz  zone  are  all separate  areas  below  the  veins. Old   2006 stuff   down there on  other  side  of  hills   but the  reason  it  was opened  up and  not  even in our  class with  still limited  drills.  8
