I intend to start a spread sheet with all the holes to date. The amount of gold and silver resource will be calculated per hole to try and come up with an approx resource identified to date at California. It wont be easy and will take some time if i can do it, at the present i am having trouble trying to get the most precise formulas to do this with. Im not sure it is right, but just for fun, i came up with hole 37 containing 161544 ounces of gold AND 598313 ounces of silver. Primed24 has given me the formulas he has, but we need the true widths to do the other holes. If these formulas are a close guesstimate that can be used, then the California is a lot more valuable than i thought! I am now very interested in doing this myself and will post my calculations when completed. If we get this working to the point that we beleive we can have a high percentage of faith in it, I will also do the cu and zn calculations. If early indications are correct then i can see why we are widely institutionally held,they havent been selling, and warrants are being exercised. Its a matter of time, how much time, i have no idea, but the more i dig, the more i think the time is getting closer. This is all my opinion, and this post may not mean anything, dont use it as an investment decision!
