It makes good sense to me. With an adit [t]VIT.v[/t] could reduce drilling costs and maybe get bulk samples to boot. They suggested it recently: "Although exploration at Cove is at an early stage, underground access to the Helen Zone for closer-spaced delineation drilling may be warranted depending on drilling results over the next few months. Access to the Helen Zone could be achieved relatively quickly and inexpensively through the side wall of the existing Cove-McCoy open pit." biz.yahoo.com

An adit is 400 dollars a foot. A gallery on a 2000 foot strike length has to be offset about 700 feet from the ore in order to get above and below the ore by 1300 feet each way. In addition once you are underground it would be desirable to put, say, 3 drifts through the ore at 250 foot intervals. So crosscutting into the ore is 500 feet, and ramping the 750 feet of lift is 5250 feet. Allow 1500 feet for raise to surface. Access adit is $400,000 with collaring. $3.1 mill for the ramp. Air Raise to surface is $835,000. Drifts of 6000 feet = $ 2.4 million. A drilling gallery of 2000 feet length, offset by a total of 1400 feet of cross cuts are 3400 X 400 = $1.36 million. $8.095 million. That would be equal to 241,209 feet of drilling. 73.6 thousand metres. 147 - 500 metre holes A dead head gallery not on ore would still be $1.7 million. That is still 50,700 feet of drilling. It depends on what is before you. Development with further exploration or resource delineation. EC<:-}
