Why is Washington H Soul Pattinson still a 38% equity shareholder?

Is today's joint venture announcement with Consolidated Potash Corp more smoke and mirrors or finally is something starting to happen and is this a reason why Washington H Soul Pattinson remains a major shareholder..... which in itself is interesting. I have no doubt that VRM are sitting on huge amounts of high quality potash but I still can't help thinking that red tape and infrastructure makes this a very long long play. Then again Washington Soul Pattinson are very very patient. They tend to be happy to sit on and guide less experienced management of sleepers with long term potential.
