The one diamond discovery that commanded the most attention at this year’s PDAC convention was Peregrine Diamondskimberlite (and subsequent diamond) discovery on its Chidliak property in south Baffin Island, Nunavut. Chidliak is 9800 km2, and since the discovery of diamonds on the property, Peregrine has added a buffer claim around the property of ~3200 km2 in area called Qilaq this February. BHP-Billitonhas earn-in rights of up to 51% in Chidliak if they spend $22.3 millionon the property over the next five years. Although BHP is spending fivetimes what Peregrine is, Peregrine remains the operator for 2009’sprogram.

Chidliak was the focus of two talks in twoseparate diamond sessions at this year’s PDAC. What is so interestingabout Chidliak is the sequence of events that led to the discovery ofthree kimberlite bodies: CH-1, -2, and -3, on the property.

Till sampling ofkimberlite indicator minerals from 2005 to 2007 confirmed thatkimberlite was present in the area. These samples indicated that 10% ofthe garnets found were G10. Last year, an aeromagneticsurvey that covered less than 15% of the property resulted in a numberof magnetic anomalies. These are commonly associated with kimberlite,but not always. Field geologists sent out to investigate the three mostpromising anomalies encountered kimberlite rock at the surface.Approximately 1100 kg mini-bulk surface samples from the CH-1 and CH-2kimberlites gave back 2.17 c/t and 0.9 c/t, respectively. This includes a 2.01 c gem-quality colourless resorbed octahedron from the CH-1 sample.
