The price of gold is rising because the values of currencies globally are falling. To paraphrase a famous economist, the value of all things are weighed against gold. That is, the value of gold appears to be increasing as the value of the dollar decreases. This is recognized as what should be a long-term trend.
The current value of copper is somewhat distorted in the current environment because global production is falling - particularly in Chile - on account of the COVID-19 pandemic. Manufacturers are desperate for supplies at present, hence an increase in prices from supply disruption - consequently, this is a short-term term event.
Look a few months out, it is reasonable to assume that as supplies begin to increase again, the price of copper will fall. For the time being then, it makes sense that gold is a more reliable bet than copper alone.
Did someone say that LBSR may have access to Carlin-style gold just north of Hay Mountain?
