2009.01.09 Per request by Whaler on Stockhouse, it is very easy to add the drill results from the latest ISM news release to the ISM Langmuir North model.However, locating these new drill holes was not as easy as they were in the midst of existing drill holes. Not being a geologist (nor fully understanding how they get their numbers), I don't think it would be too far to guess based on the location that these new results will not add anything significant to the overall size of the ore body. Further, I'm a bit stumped on the rational and cost justification for at least two of these new holes (particularly an exploration play) - but will assume the geologists know what they are doing. LN08-124 is virtually parallel to LN06-31. The collar is 17m away on the surface, with grade strikes only 6m distant on the top and 3 meters distance on the bottom. LN08-125 appears to be the only real informative hole in the bunch - though one could guess it helps define the continuation of results from LN07-101 and LN08-104. Unfortunately, this ore is in that grey area of Open Pit wall limitation based on property boundary conditions (which hopefully will be clarified in the long awaited 43-101). LN08-126 is another exploration hole I don't understand the rational for (quality control or difficult geology maybe?). This one almost intersects LN05-20 (less than 3m distance) at the top of the ore zone and angles off to a distance of ~16m at the bottom. "Estimation of ore reserves and grades from sample assays based on simple arithmetical averages leads to fundamental error; statistical averaging is required. On the other hand, even sound statistical procedures (e.g. geostatistics ) when employed by gifted amateurs can do more harm than good."

The grid orientation conforms to the dip or plunge of the orebody... A spacing of 200 feet by 200 feet (60m by 60m) is commonly employed.
