Naakenavaara Geology

The geology of Naakenavaara is poorly known owing to extensive peat bogs in the area, but limited diamond drilling  and geophysical maps have provided intriguing glimpses of the geology of the project.

Much of the previous work on the project has been directed at the OKI Copper-Gold Zone that is now known to extend for upwards of 2.5 km on the project. This zone is characterized by intense quartz-albite veining associated with chalcopyrite and gold mineralization. While much of the copper mineralization is visible as chalcopyrite, the gold is microscopic and cannot be seen by the naked eye.

In April of 2010, a small drill program was undertaken to test a number of geophysical anomalies that were found to the south and east of the OKI Zone. These drill holes were targeted on a number of geophysical anomalies that appeared to be massive sulfide mineralization. Drill Hole N-5 intersected a previously unknown zone of massive sulfide mineralization that is highly enriched in nickel and cobalt. A photograph of this drill core is shown below and shows the massive nature of the sulfides complete with sericite alteration. This drill hole intersected 0.43% nickel and 0.22% cobalt over 2.55 meters, but the thickness of this massive sulfide zone is unknown since the drill hole was collared in mineralization.

All of the remaining drill holes also intersected mineralization of note, and the photograph below shows some of the disseminated sulfide from drill hole N-2. The disseminated sulfide zone was also highly enriched in nickel and cobalt, and intersected 0.33% nickel over 4.06 meters and 0.13% cobalt over 4.83 meters. There was also 0.12% copper over 15.57 meters.

While these intercepts provide tantalizing information about what could possibly lie under the ground at Naakenavaara, much more drilling and trenching is being completed this summer to find the full extent and tenor of mineralization at Naakenavaara.
