I feel You are both right and wrong in your assertions Yes...

I feel You are both right and wrong in your assertions Yes Davinci is obviously a blind deposit as there is no surface expression ie porphyry .
Yes in that like you I feel the 100koz is probably at this stage not valid because as you state the upper section holes are too far apart and they have added uneconomic tonnage to the resource
Based on my calculations from about 8 months ago I feel there is around 70k economic ounces but at a lot higher grade that LJ is giving it credit for in this announcement as he is now including the upper low tonnage sections as you mention hopefully he is doing this as a case of under promising and over-delivering on grade (not ounces) and it is the grade that will give the profit

Eshman posted this back in June at the time, more fool me I was in silent agreement with him
"Not good for the future in my opinion and the Da Vinci code is receding into obscurity with noncommittal language replacing the previous more bullish sales pitch."

Looks like his prophesy is looking more like it is incorrect but we will have to see what Da Vinci ends up reconciling at on the ROM pad for final validation .
