From my DD so far, previous explorers and MGP originally were looking at a deeper underground gold mine, as that's what the exploration was showing (and still shows). However, further exploration and analysis revelaed both a gold find close to the surface, plus tungsten close to the surface, appropriate for a gold/tungsten open-pit mine, which is much cheaper to develop. Presumably, over time, the nature of the project can change with new finds plus changing market conditions. It's a very, very large property.
