Twin finds indicators on two anomalies at Jackson

Surface sampling by Twin Mining (TWG-T) at the Jackson Inlet property on Baffin Island has retrieved kimberlite indicator minerals from the soil above two magnetic anomalies.

Twin crews spent part of the recent field season taking surface samples from anomalies located by an earlier airborne magnetic survey around the Freightrain kimberlite, where recent sampling found diamonds. The initial soil sampling at two anomalies, which has confirmed three typical kimberlite minerals in the soil, was meant to separate the magnetic anomalies that were due to kimberlite bodies buried under the overburden.

Heavy-mineral concentration work on a 26-kg sample of soil from magnetic anomaly AN-04B, 4.5 km southwest of Freightrain, found 20 grams of kimberlite-indicator grains, of three minerals — pyrope garnet, eclogitic garnet, and chrome diopside.

Samples weighing 33 kg and 27 kg were taken from anomaly AN-08, 30 km southeast of the Freightrain occurrence. The larger sample yielded 78 grams of the three indicator minerals and the smaller one 84 grams.
