RE: What will be good drill results
RE: What will be good drill resultsI think deadfred's guess would be more than a 'good' result: it would be a 'great' result.
A 'good' result would be a reconfirmation of the discovery hole results, hopefully on more than one hole. As you recall, this was:
02ML-25 9.10m 0.62%
incl.__ 4.80m 1.20%
__incl. 2.10m 2.50%
__incl. 0.40m 12.0%
One thing that's very apparent is the tremendous difficulty in establishing good mineable uranium orebodies. Just look at the scarcity of good deposits. That's why I believe that confirming and extending the discovery hole numbers would be a very positive step.
Look at the existing orebodies in the region:
Cluff Lake
depleted - total production 62.5 million lbs
McArthur River - depth 530-640 metres
437 million pounds reserves; 23.7% average ore grade
Cigar Lake - depth 450 metres
232 million pounds reserves; 19% average grade
Key Lake
mined out; 700,000 lbs reserves; 0.5% average grade
McLean Lake
47.1 million pounds reserves; 1.7% average grade
Midwest Project
36 million pounds reserves; 4.5% average grade
Rabbit Lake
17.6 million pounds reserves; 1.3% average grade
open pits mined out; now underground
Here's a 'positive' drill report by Denison earlier this year, relating to their producing McLean Lake property:
"ENCOURAGING URANIUM DRILLING RESULTS AT McCLEAN
TORONTO, April 12, 2002 - Denison Mines Limited announced today that a winter exploration programme at the 22.5%
owned McClean Lake mine site in northern Saskatchewan (operated by Cogema Resources Inc.) has discovered new
unconformity related uranium mineralization in the Athabasca sandstone. Approximately 20 diamond drill holes have tested structural and geological targets in the Caribou Lake area, approximately two kilometres northwest of the Sue C open pit.
Interesting uranium intersections have been returned from vertical holes S-693 and S-700, drilled 10 metres apart, on a section across the assumed geologic strike. These holes were drilled to test, at the unconformity, the up dip vertical projection of a basement graphitic zone. The following table presents the results of the significant intersections at this time. All data is expressed as equivalent uranium grades at a 0.1% cutoff from downhole radiometric probing.
Note: 0.1%U = 0.117924% U308
Diamond Drill hole S-693

All data reported herein are based on downhole radiometric probing. This data is subject to confirmation by geochemical analysis on the drill core which will be completed in approximately six weeks.
This exploration programme is at a very early stage in a geologically complex area and no conclusions can be inferred as to continuity, orientation, dimensions, or controls of this mineralization. Further work, including geophysical surveys and diamond drilling, will be carried out on this prospective target before an economic assessment is made.
