If I could add a little input. Ive make investment and sat for a year +, then all of the sudden interest starts to shows up. From my understanding on this deal, they did a raise and currently have $3.9M+ in the bank. Just received a stabilization patent approval is June 2021 and management has been exercising options at .38 cents. I do see active warrant at .40 cent but they bring in more money and I believe they are not net issuance which is good (please look I'm going by my memory on this). But, all UN is seeking munitions that are in this category (Drone). And, if you look at the team in place, they all seem to be very capable for their job positions. So, if it dips I'll personally add more.
Unless the US dollar goes bust and the world go Crypto's or want to use another currency backed on Lithium or fractional gold.
I have to say this deal at these prices make sense to me.
