I have bought a chunk over the last 5 or so months, after having done significant research. This stock appears the biggest no brainer I have come across which makes me nervous. The site has been previously mined, vanilla extraction process, great location ( transport, close to Cal food bowl), expected growing demand for products and none of key suppliers are US companies. Am thinking of continuing to buy, am I missing something here? What are the key risks in you eyes?
