I am working in this industry, I involved original estimation of PLS plant equipment years ago. PLS had 20% less equipment cost then the original pricing. All new company get proposal from vendor for brand new and fancy equipment cost. However reality is different then this situation, there is always competition, bargaining and naturally discount. It is inevitable and good for miners and producer. In this case TMT can save 15%-30% from equipment + transport, energy.
