Rusoro has a case against the Republic of Venezuela due to Venezuela's expropriation of their gold mining assets, which equates to about $1.4 billion. This has been ongoing over quite a few years and you can see from the chart that it has had periods of time where it has spiked and then come back down to lower levels. I purchased at the .05 level.
Recently, the U.S. Court of Appeals (3rd Circuit) affirmed that Venezuela's state-owned oil company is the country's alter ego and that the property may be seized in satisfaction of the Republic's judgment debt. I think a lot of people are speculating that this is getting a lot closer to an actual conclusion.
