Difficulties re mining & impurities

There are two popular stocks on the ASX that Squire believes could face challenges from here: Latin Resources (ASX: LRS) and De Grey Mining (ASX: DEG). These companies have seen their share prices rise 170% and 29% respectively over the past 12 months. "If you go back to the criteria that I mentioned before - you have a look at Azure, Patriot, and Liontown - they've all got really thick deposits that are high grade," Squire says. "Yes, Latin Resources is a reasonably large resource, but it has multiple skinny loads. It will be very difficult to mine and there is a high risk of impurities coming into the concentrate they process." Squire believes the market is starting to wake up to these technical challenges, with the stock's share price falling 35% since hitting a high in August. "It's starting to fall apart and that's being reflected in the numbers as people start to think about the next stage of production. I think it's got the potential to fall further as we start to see those challenges surface," he says.

Let me start by saying that I am NOT a downramper; I have held LRS for quite a while and enthusiastic about their prospect.

However, reading the above article on Livewire 17/10 I wonder what others feel? Not being an expert, I don't feel fully equipped to comment, but would greatly appreciate feedback.
