Resumé

Nalunaq is a small, high-grade gold deposit located in South Greenland which requires a new exploration programme in order to locate new areas of significant gold mineralisation. 3D implicit modelling of the deposit identifies potential areas for further exploration. The model constrains a number of post-mineralisation faults which correlate with areas of low gold grades. Arsenic acts as an effective pathfinder element for gold, highlighting areas of potential interest away from the main gold-bearing vein. No correlation between changes in host rock lithology and gold grade are noted. A biotite granite intrusion post-dates the gold-quartz veins, and assessing the extent of the intrusion will be useful in determining the limit of additional gold mineralisation. A renewed exploration programme at Nalunaq would have to consider the effect of the late-stage faults on deposit geometry and gold distribution
