The Financial Post reports in its Friday edition that several class action lawsuits have been filed against Barrick alleging it misled shareholders about the fallout of its most recent cyanide spill at a flagship mine in Argentina. The Post's Sunny Freeman writes that the class actions claim the company misled shareholders in public statements it made after a March rupture of a pipeline carrying a gold-cyanide solution at its Veladero mine in Argentina -- the third spill at that mine's leach pad in two years. In the immediate aftermath of the pipeline rupture the company said it did not expect the incident to have a material impact on its bottom line, despite the fact that provincial authorities in Argentina had placed restrictions on its operations. Barrick left the mine's annual production guidance unchanged at between 770,000 ounces and 830,000 ounces of gold at all-in sustaining cost of $840 (U.S.) per ounce to $940 (U.S.) per ounce. However, in an update contained in its April, 2017, first-quarter earnings release, the company cut its outlook by 12 to 18 per cent -- to 630,000 to 730,000 ounces of gold. That also included a reduction in its take of output due to its 50-per-cent sale of the operation.
