and as required by the Danish Maritime Authority, Guidelines of 10 January 2011 - a navigational safety investigation has been undertaken. This report has been prepared to show that navigation can be carried in a safe manner. 1.1 Terms and abbreviations The following terms and abbreviations have been used in the Navigational Safety Investigation report: BIC Baffin Island current BRT (see GRT) DMA Danish Maritime Authority DMI Danish Meteorological Institute DWT Dead weight tonnage EIA Environmental impact assessment FS Feasibility study GPS Global positioning system GRT Gross register ton HAT Highest astronomical tide IHO International Hydrographic Organization IMO International Maritime Organization IMR Inspection, maintenance and repair KMS The National Survey and Cadastre kts knots LAT Lowest astronomical tide m3 Cubic metres MBL Minimum breaking load MRCC Maritime rescue coordination centre File: REP0019 - Navigational Safety Investigation, rev. 3.docx TANBREEZ Project August 2013 Navigational Safety Investigation Revision: Rev. 3 791261/KAKU Page: 7/43 MSL Mean sea level nm Nautical miles PC6/7 Polar class 6/7 RAL Royal Arctic Line RCC Rescue coordination centre Rimbal Rimbal Party Ltd ROM Run of mine ROV Remotely operated vehicles SAR Search and rescue SRR Søndrestrøm search and rescue region WGC West Greenland current File: REP0019 - Navigational Safety Investigation, rev. 3.docx TANBREEZ Project August 2013 Navigational Safety Investigation Revision: Rev. 3 791261/KAKU Page: 8/43 2 Project background 2.1 Location The project is located in Killavaat Alannguat (Kringlerne) in South Greenland in the bottom of the Kangerluarsak Fjord between Narsaq and Qaqortoq (Juliane- håb) in an area bounded by latitudes 60º 51' N and 60º 54' N and longitudes 45º 48' W and 45º 52' W. TANBREEZ Project Figure 1, South Greenland - project location 2.2 History The project area has been explored since 1986 by a number of companies. Un- til 1991, at least 2,500 m were drilled (60 holes) and 70 tons of ore were bulk sampled for further studies. Environmental investigations were initiated, and ore and tailings were studied. In 2001 Rimbal Pty Ltd (Rimbal) acquired the license and has up, until 2007, completed e.g. channel chip sampling, preliminary physical and chemical test- ing of samples, literature collation and limited product marketing research. Since 2007 Rimbal has carried out a new drilling program as well as social and environmental baseline studies. In 2010 a Feasibility Study was prepared for the project.

The mine area is located on the south-eastern side of the fjord, and port and process facilities will be located on the south-eastern shore line at the bottom of the fjord. The fjord is mostly surrounded by mountains with steep sides, and the mouth of the river Lakseelv is located at the bottom of the fjord. Narsaq TANBREEZ Project Qaqortoq Figure 2, Project area File: REP0019 - Navigational Safety Investigation, rev. 3.docx TANBREEZ Project August 2013 Navigational Safety Investigation Revision: Rev. 3 791261/KAKU Page: 10/43 Overhead power cables cross the fjord approximately halfway in. The cables run from the hydropower plant located south-east of the TANBREEZ Project to neighbouring towns. The power cables run from the southern to the northern shore of the fjord and cross over two small islands. See Appendix A, "Cross section, overhead power cable". The closest towns to the TANBREEZ Project are Qaqortoq 20 km in a south- western direction and Narsaq 12 km to the north-east. Qaqortoq is the forth-largest town in Greenland, with 3,300 inhabitants. Narsaq is also a relatively big town with 1,650 inhabitants. Both towns' economy is based primarily on the fishing industry and tourism. For more information about existing port facilities in Qaqortoq and Narsaq see Section 7. 2.4 Project overview including infrastructure The life time of the mine is 10
