I am wondering of a "Rubidium Mine" is a viable thing. Reading up on Rubidium it is not an established, traded commodity market. The internet suggests prices of USD 1,000 / kg for Rubidium Carbonate and USD 125,000 / kg for the metal --- so it must be hard to turn the carbonate into metal. But, the USGS report on Rubidium from 2017 suggest the US market is 2,000 kg in total. If a resource was 1% Rubidium - then you would need to mine 200 tonnes of the resource to meet annual US usage (if my maths are right). A mine generating 200 tonnes of ore a year does not sound that compelling

I therefore wonder if Aldoro needs to invest in research work that develops uses for Rubidium that creates enough demand to make mining at volume an economic activity? I see some companies developing both resources and processes or uses for their materials. ATC for example with their HPA and is of HPa in coating battery materials.
