10 million $ could raise the sp to way more than 50 cents but what then?
The volumes traded now are low so that 10 million $s would probably buy at best 20 million shares. You have to be aware that as you are buying in a low volume traded the sp appreciates fairly quickly, then the sellers for profit come in stabilizing the price but you are paying their price. Those shares would not go for 30 or even 50 cents.

Asuming you obtained 20 million shares for the 10 million $s and the sp was a $ at the end. How long would the sp remain there once the action is over? Within days it would drop to 50 cents, imho.

Fine that is 20 cents higher than now. Granted also that from then on the sp would decline much slower. Maybe a penny per day.
Should it return into the 30s then perhaps a penny per week.
The price would rise quickly AND drop quickly.
A PP is almost never at today's price but often on an average of say a month.

Assume you are the financier for that PP, would you give 50 cents if the average was 50 cents? I think not.
40 cents is more likely and that with some incentives to boot.
We have to be aware that such financiers do research on a share's history and if it has such in the 30s range then they push for that or else nothing.

Wether we spend the 10 million or not, the company will use up millions of $s while we wait for the infrastructure news. The more pertinent question is what will we have in the piggy bank when the news arrives. I say do a PP after the news if we can.

The short of my comment is that we are wishing ( Yes I do also.) but reality is often sobbering. No I do not want to rain on anyone's parade but just maintain awareness.

Cheers.
