$50/t profit is more than viable at 1.6Mtpa ,
Not hard to scale up , they just need to get cracking , generate cash then it's easier to raise cash at higher prices, they can expand very easily , and throw few million at drilling and proving up the resource . Getting to production no matter how small as long as it's viable should be the goal in my opinion , but I suppose they are hindered when it comes to offtakes or funding if it's a smaller scale operation or not generating enough cash , who knows , all guess work at the minute as usual .
