Greenland Minerals finalising updated civil cost estimate for Kvanefjeld Rare Earths Project

On‐site studies were conducted by a multi‐disciplinary team of engineers from Tetra Tech, Nuna Logistics, PND Engineers and C‐CCC.

Updated port designs completed

Greenland Minerals Ltd (ASX:GGG) is continuing to advance the engineering optimisation studies for its Kvanefjeld Rare Earths Project in Greenland, including an updated civil construction cost estimate.

Port design optimisation

The North American arctic specialist port design company PND Engineers has completed a design optimisation for the port facilities.

The location of the port facilities at the Tuna Peninsula has been enhanced to allow for increased use of local construction materials.

This will reduce the overall capital cost of the project by taking advantage of the abundant source of good quality aggregate material available for port construction.

The port location on the Tuna Peninsula is located at the base of the Narsaq valley in an area that is currently used for a municipal rubbish dump.

PND Engineers have recommended the use of Open Cell Technology for the project as it offers the lowest cost and least construction risk.

Design of on‐shore facilities

Chinese company C‐CCC has worked collaboratively with PND Engineers to provide the on‐shore port design and cost estimate for associated facilities.

C‐CCC has provided an extensive design of the on‐shore facilities for an efficient port operation.

The company has included flexibility within the design to allow for a staged development strategy and delivered a high level of design detail for the updated cost estimate.

Optimised civil design

In November 2018, Tetra Tech redesigned aspects of the project to optimise civil design, that led to a dramatic reduction in civil earthworks associated with project development. 

Cut and fill quantities were reduced to about 20% of the original design.

Nuna Logistics is currently compiling an updated civil construction cost estimate for the project based on the new civil design. This will detail the cost reductions accurately.

The updated estimate is based on new information gained from the site visit, and the revised studies by the participating engineering firms.
