Just recently, Robert Friedland's Ivanhoe Mines released a PFS study.
Here is an article on it -- PFS - Ivanhoe Mines
Ivanhoe mines is currently sitting at about $500 million market cap.
The NPV sits at $972 million @ 8% discount
Eric Friedland's (brother) Peregrine Diamonds (pgd.to) will be releasing a PEA in next 12 to 16 months.
With bulk sampling from both CH7 and CH44 and continued conversion of TFFE in CH6, there is significant chance to exceed what Ivanhoe's PFS has created.
Could younger brother Eric's project exceed Robert's project over time?
Ivanhoe has a much larger project, Peregrine Diamonds has a much more valuable project.
Of note, Robert owns shares in Peregrine Diamonds as well as Ivanhoe.
Peregrine Diamonds sits between $40 to $50 million market cap, representing 1/10th of what Ivanhoe is worth.
