I thought Milestone was an asset that could be sold to raise money...apparently not.
Milestone is a low grade and (potenially) high tonnage deposit. These types of properties can be very lucrative but it takes a huge investment and time to prove up a reasonable amount of tonnage to make the property valuable.
Brian is betting that his 30% share is worth more than if he'd dropped millions more into the property to sell it to someone else. Besides with their focis on Magino, it would be a long time before PDG would get around to drilling more of milestone.
Seeing as only 99% of deposits ever become mines, it's a good way to get some low-risk leverage on a property that has some potential than letting it sit in mothballs for 2 or 3 years.
If Goldstream is serious about making Milestone a viable project they will spend more than $2 million over the next 2 years and Prodigy can only benefit from that.
