The partners are particularly encouraged by recent step-out drilling which is showing evidence that a thick high grade zone exists to the north of the 21 zone.
Recent wide-spaced step-out drilling, including eagerly-awaited hole 109 spotted some 1,000 ft from an earlier hole (which also returned high grade gold), “hit the zone very strong,” said Chester Idziszek, chief geologist for Pezim-controlled Prime Explorations.
Results are expected shortly, however the hole is reported to have intersected a 50-ft interval containing sections with significant visible gold mineralization.
Calpine President Murray Pezim is already calling Eskay Creek a “world class” deposit.
“We can now see in excess of 10 millions tons grading about 0.5 oz gold on average that appears to be open pittable,” he said.
Idziszek said the two-phase 1989 program is designed to get a handle on the size of the 21 zone in the first phase, while the second part will be aimed at drilling off the zone.
“The 21 zone appears to be open pittable and is much larger than we thought and it is still open,” said Idziszek.
A total of 23 holes have been completed so far on the step-out drilling portion of the 1989 Phase I exploration program. The majority of this drilling involves 50-m step- outs along the strike extent of the 21 zone mineralization.
Calpine says it has traced the 21 zone mineralization over a minimum strike length of 1,100 m, with the zone still open at depth and to the northeast.
The latest results include: 91.8 ft grading 0.453 oz gold and 16.91 oz silver including 42.6 ft of 0.897 oz gold and 32.20 oz silver and including 13.1 ft of 2.53 oz gold and 102.20 oz silver. Hole 89-101 returned 55.8 ft grading 0.867 oz gold and 19.92 oz silver which includes 22.9 ft grading 1.91 oz gold and 43.77 oz silver per ton.
The in-fill drill program was designed to augment the previous drilling pattern for the upper 100 m of the 21 zone.
