Are you sure? Wouldn't that depend on amounts of and or grades of ore, costs and the pricing of the metals. A 980c loader could feed 150 tons in a lees than an hour if the crusher could handle it? I hope it is not a miss print. If not a mis print, it would suggest they have the "goods" so to speak, would it not?

In brief this 150 ton per hour is miss print or miss information.
150tons per hour is a huge capacity. To buy, install operate and feed that type of plant need require lot of financial resources. Even a crushing plant of that capacity is too expensive for such a small tiny company and if at all they manage to buy such plant, it need several dump trucks of 15 to 20 tons capacity to feed it. Of course those dump trucks need hydraulic shovel or wheel loaders to load the blasted material.
