IMO its economic related with an immediate affect on HDY. The Argentinian Peso has fallen 16% last week and 50% this year, this can be a good thing for HDY but bad for Argentina, so to counter it the Government overnight has imposed a new tax for exports to start immediately until 2020 while it tries to balance its budget. There appears to be uncertainty around the tax level for 'raw materials' with some experts saying 7% and others 10% increase. Lithium has been identified and a few ASX Argentinian trading stocks are also in trading halts whilst their management understand the new tax to report shareholders. Argentina is reliant on IMF funding and is currently requesting 'faster payments' and last week moved its interest rates up from 45% to 60%. HDY's joy of 'risk vs reward'
