With access to the latest in mine shaft and ramp development costs and performances, Cementation has carried out a number of tradeoff studies evaluating what is the best option for a mine access.

The Sao Bento project in Brazil was owned by Eldorado Gold and Cementation evaluated the possibility of shaft deepening versus ramp extension. An important element of such evaluations is the operating cost aspect which will impact the final NPV of the project.

Cementation has also carried out studies for Voisey Bay Nickel regarding the underground access options to their Voisey Bay project.

In all of these evaluations cost and schedule are developed in detail from first principles and benchmarked against current pricing on other similar projects.
