RE:these guys could sign with the biggest gold miners in the I think the problem is that very few investors following this stock. Also, there are very few trades regardless of price.
I do think that DST's tech is a game changer in mining for arsenic containment, but also for site clean-up. However, they likely will not see a significant jump in share price until they have increased revenue and turn a profit. This last contract is only for $100,000, so while it is significant as to what it could lead to, on its own it is not.
For the last 4 years this company has had revenue, but has yet to turn a profit. More importantly, their revenue has been relatively flat for the last 4 years. They need to prove themselves as a profitable company. Hopefully that is coming soon.
It may be a good time to accumulate shares if you are a long term investor. Revenue and hopefully profitability could improve quickly. The market cap for DST is currently $5.3M. This is not much, although it is small company. This may provide for a significant upside.
Just my thoughts.
