2017 / 2018 / 2019 cashflow projections (@ 22 September 2017), page-59

If the rubies were coming out of the graphite ground I might tend to agree. However, these are 2 completely different entities with 2 different revenue streams. If a copper mine has to close for maintenance or full shut down, there goes your silver. This is not the case here.
Mustang is a mining company, to be potentially mining 2 different commodities of which no one at this point knows which will be bringing in more revenue. The only connections between the 2, is that they are both in the same country and run by the same company.

The graphite is in early early stages and still many boxes to tick. Still a great place to buy in, if it were only graphite Mustang was offfering. Mustang maybe able to use some of the capital from the rubies to fast track it, funding it to production. Imo maybe 2019.
The rubies will be bringing revenue in 5 weeks and we are still at bulk sampling stages.
Holey Moley!

All Imo.
