Darnley Bay entered into an updated agreement with the Inuvialuit Regional Corporation in 2009 for the rights to explore the largest land-based gravity anomaly in the world, located on the Arctic coast of Canada near the town of Paulatuk. The company has spent in excess of $20 million on the property since the 1990s, including a program which discovered a number of diamondiferous kimberlite pipes. However the main target remains discovering the source of the large gravity anomaly, which measures some 100 X 60 kilometres. Geophysics has also outlined a large, coincident magnetic anomaly. Base metal deposits are often detected using gravity and magnetic surveys.
A number of geophysical programs over the years has given the company a deep understanding of the anomaly, including a magneto-telurics program in 2013 which outlined several 3-4 kilometre-long structures which remain undrilled due to lack of funds. The independent Geological Survey of Canada has conducted a number of programs on the anomaly as well, and has stated “The Noril’sk exploration model is applicable by almost every criterion.” Noril’sk is located in Siberia and is the largest nickel-copper deposit in the world, originally containing some 2 billion tonnes grading 1.77% nickel, 3.57% copper and 9.5 grams per tonne PGMs.
