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
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.
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
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
