Diving into resource estimates, PEAs, PFSs and other economic studies

June 17, 2019

Brian Leni, Founder of Junior Stock Review joins me to share his thoughts on the main aspects of resource estimates and economic studies that companies release. Anytime a resource or economic study is announced there is a lot of information behind the headline numbers. Brian shares with us what he finds most valuable and some of the numbers he watches closely when doing his DD.

    Look what happen to MMSDF Macathur mineral today. I would like for Cory to get them for a sponsor.
    Macarthur Minerals Limited is an iron ore development company with its focus on bringing into production, its sizeable, 100% owned, Moonshine Magnetite and Ularring Hematite Iron Ore Projects in Western Australia. Macarthur Minerals also has prominent (~1,130 square kilometre tenement area) exploration interests in gold, lithium, nickel, cobalt in the Pilbara region of Western Australia.

    Good interview today Cory & Brian. It is interesting to dissect the wacky world of economic studies that the mining industry dishes out.

    PEAs are just a crapshoot in the dark, and give a glimpse of if a project could be an economic mine, and they’re necessary to gauge whether or not to kill the project, or keep going. Of course most massage the numbers so they can forge ahead with a lifestyle company, but reality is that the numbers are often pie-in-the-sky assumptions.

    PFS and FS studies are better (but they still lowball a number of jurisdiction risks, inevitable milling or processing ramp-up issues, the actual smelter penalties, realistic starting metallurgy recovery rates, realistic fuel costs to ship ore, and environmental concerns from local communities that may require much more than the minimum bar required in construction for a tailings dam, environmental studies, water treatment concerns, and on… and on….

    As for the capital needed – I agree with Cory that it is never enough in the initial economic studies and those numbers are disingenuous on many levels. Most companies really lowball the capital needed to be raised to make their ROI look better, but then end up needing to raise far more than initially projected. They’ll end up doing a 2nd or 3rd capital raise during development due to (XXX or YYY challenge coming up, or dingbat consultants suddenly recommend adding updated equipment to improve throughput or recovery…). Many of them know they are short-changing what they’ll actually need, but often when they are 85% there, other key investors will come in and raise the final bit needed, but this further dilutes investors that jumped in off the assumptions of the filed PFS or FS.

    All of these things that crop up and surprises companies, add to the capital needed to be raised, and really they shouldn’t be a surprise to experienced teams. What is sad is the industry just repeats this song & dance over and over again, and reacts like these stumbling blocks and extra capital needed to be raised couldn’t have been foreseen – total BS! (just look at what happened to the last several hundred companies that decided to go from explorers, to developer, to producer and it is a clear trend of diluting and raising money, rinse and repeat.

    As for the NPV – yes 5% is mostly a comical assumption, unless the mine is going to be in Nevada or a few key provinces in Canada. Most of the world’s jurisdictions need to have 7-10% NPV discount factored in, and some need a 15%.
