The PFS, the resource estimate, the cash position, the tiny EV, the minimal capex and dilution required to get to production, the large investors, the ground left to drill, and the team is serious about mining gold. Apart from that nothing
I was invested in MUS back in 2016 when it had a similar lack of market interest to EGA. The SP of MUS dropped and dropped going from 6c down to 2c. Almost nobody was interested in it, but I kept buying until I ended up a T20. All of a sudden it became HC flavour of the month and ran up to 20c. Of course I didn't sell out at the top like I should have as I believed the MD's stories, but I am willing to back my convictions with my cash.
EGA might end in tears like so most speculative miners, but I think it has a better chance than most.
