As mentioned they do have financing in place for the Australian gold & silver operations. I believe, they haven’t done anything with Mt Carrington due to the silver price being lower than what they’ve expected. Remember they acquired that asset in 2010, then the following year the silver price skyrocketed to $50 per ounce.
Conclusion: Without the silver price moving higher the assets will likely just sit there unless they find a heap more gold or the gold price trends a lot higher. At the moment Mt Carrington is really a silver mine with the added benefit of a few hundred thousand ounces of low grade gold.
