Gold recovery from the sulphide plant will average 96% over the life of the mine.
Drill hole M6 encountered massive sulphide mineralization at a vertical depth of 50 m, consisting of a 7.
The objective of this work was to study the sulphide formation process in the pressure pipes and the influence of sulphur-rich wastewater on oxygen consumption of activated sludge of Kohtla-Jarve WWTP.
The 2006 work program at the Ultra property consisted of property wide geological mapping and geochemical sampling, detailed mapping of known showings, grid MMI soil geochemistry in areas of geophysical anomalies previously identified near the massive sulphide boulder zone, and trenching and helicopter pad building at the Telluride showing.
In developing its new production schedule, Alacer placed emphasis on maximizing production from oxide ores between now and startup of the sulphide plant and also on producing the highest-grade sulphide ores during the initial years of sulphide production.
During the initial years of production, exploration of the underlying sulphide portions of the deposit may result in additional material being added to the mining plan.
No sulphides of interest were intersected that explained the conductor location.
Both gold and base metal massive sulphide mineralization targets are expected to be defined by the geophysical surveys.
1 m in a gold-bearing sulphide zone further to the south.
The marked base-metal increase towards the stronger part of the anomaly is very promising for this zone, pointing to the possibility of an economic massive sulphide mineralization.
In the three drillholes (NO-05-01, -02 and -06) that reached the depths of target IP anomalies, the amount of disseminated sulphide mineralization is very weak, and may or may not account for the anomalies.
The drill program continued to confirm extensive broad areas of sulphide mineralization with polymetallic (Au, Cu, Zn & Ag) values in a major volcanogenic massive sulphide-epithermal environment.
