NI43-101 Resource Estimate

Grängesberg Iron AB has received an NI 43-101 Technical Report from Roscoe Postle Associates Inc (“RPA”) showing a compliant resource estimate for the Grängesberg Mine. The Technical Report which was prepared by RPA and was dated 26th September 2014.

RPA concluded that the Grängesberg iron ore deposit hosts a significant iron resource that has excellent potential for expansion at depth. Geophysical interpretations from the 1960s suggest that the ore body continues to at least 1,700 meters below surface. Diamond drill holes confirm the mineralization continues to at least between 1,100 to 1,200 meters below surface. In RPA’s opinion, more geotechnical, metallurgical, and other engineering studies are warranted to advance this Project. A summary table of the resource estimate can be found following this link:

Preparations for the environmental permit
Grängesberg Iron are working on preparations for an application for an environmental permit for the mining operations in Grängesberg. This also includes the dewatering of the mine.

 

Mining concession granted for the Grängesberg iron ore mine
On the 14th of May 2013, the Swedish Mining Inspectorate granted Grängesberg Iron AB a mining concession for the iron ore mine in Grängesberg. The mining concession is an important milestone on the road towards re-opening the historic Grängesberg iron ore mine. A mining concession in Sweden is valid for 25 years, and is then automatically renewed every ten years if mining is on-going. The application for the mining concession contains a preliminary environmental impact assessment.

Co-operation with Atlas Copco
In early October 2012 Grängesberg Iron and Atlas Copco Mining and Rock Excavation Technique Sweden signed a Letter Of Intent about co-operation regarding mining equipment and technical solutions for the future mining operations in the Grängesberg mine.

 

Pre-Feasibility-study successfully completed
At the end of March 2012 a Pre-Feasibility Study for the Grängesberg mine project was completed. The results of the study show very good possibilities for profitable and cost effective operations in the Grängesberg iron ore mine.
