I will have a look into the ELT projects as they sound interesting and I'm LT bullish on Tin.
Do they have a JORC compliant resource and any feasibility studies? I usually don't invest in exploration/development companies without this as I like to know the likely economics of the project. If it ticks that box then I'm onto management; if it ticks that box I'm onto the develpment story and any potential upside to the economics; If it ticks all those I'm probably in.
