NuLegacy reports there are now three drill rigs operating on the Red Hill property.
The reverse circulation (RC) truck rig that arrived on April 25th has completed three deep holes into the recently discovered Avocado deposit (samples from these holes have been sent for preparation and assaying) and is now drilling two holes to test the new Deep Iceberg anomaly - http://nulegacygold.com/i/pdf/ppt/2017-04-21/0016.jpg - that lies beneath and between the North and Central zones of the Iceberg gold deposit. The truck rig will then circle back to drill further holes in each deposit as guided be the assay results from the first set of holes.
A second RC rig and a core rig have just arrived and will, over the next six to eight weeks as access conditions improve after the 'wet' winter, drill the first dozen of the 24 holes currently planned for the expansion of the Iceberg gold deposit's established exploration target(i).
Leach tests: NuLegacy reports that bottle roll leaching tests conducted by McClelland Laboratories, Inc., of Sparks, NV confirm the Iceberg gold deposit's oxide material has favorable leaching characteristics.
"We are extremely pleased with the high extraction percentages from these tests," comments Dr. Roger Steininger, NuLegacy's CGO, "The results are in line with expectations for typical oxidized Carlin-type gold deposits in Nevada."
In summary, oxidized gold bearing drill hole intervals were selected from throughout the Iceberg deposit, and submitted for bottle roll tests. The average extraction for all the oxidized samples was 79.3% with most of the gold extracted from each composite during the first six hours of the tests. Extractions ranging from 73.5% to 87.8% were reported for the oxidized material.
Fifteen drill hole composite samples were each subjected to 96-hour agitation (bottle roll tests) leaching in a dilute solution of sodium cyanide, after which the pregnant solution was analyzed for gold content and the percentage of gold extracted from each composite was calculated. McClelland Labs concluded that the material in the composite samples was "amenable to agitated cyanidation treatment".
