what Ian Stalker said about PNGI find this an interesting retrospective of K92's early days, and the nature of the realities in which they found themselves.
Ian Stalker was their CEO from 2014 - 2016, and this was from a 2016 conference he spoke at. Stalker has over 45 years in mining, around the globe.
It's especially interesting how much respect he has for both the governance of PNG, as well as their handling of the mining within that country.
Here, in 2021, he remains as a Director of K92.
