Twin to test Baffin anomalies

Twin Mining (TWG-T) is gearing up for a 2,000-metre drilling program on its Jackson Inlet property on Baffin Island.

The program will target the Freightrain claim, a cluster of 16 kimberlite pipes coincident with a magnetic anomaly whose diameter measures 500 metres.

Also targeted are 11 other magnetic anomalies with comparable magnetic signatures. Eight occur between 2 km and 11 km apart along a 30-km-long trend. The three other lie about 20 km south of the trend. They range in diameter from 30 to 600 metres and are all near the surface.

A small sample from one of the anomalies, No. 3, yielded some G10 garnets and chromite grains, which are typically associated with diamond occurrences. A larger sample will be collected shortly.

Previously, two trenches, measuring 23.8 metres and 16.4 metres respectively, exposed unweathered bedrock kimberlite on Pipe 1 on the Freightrain claim. Seven samples, totalling 412 kg, were taken from the first trench and 4 samples, amounting to 380 kg, were collected from the second trench. Another 95 kg of random samples were taken from weathered kimberlite on the surface.

Seven samples from a 24.3-metre trench, which was driven into fresh bedrock in Pipe 2, weighed in at 474 kg. A total of 86 kg of random samples of weathered kimberlite were also collected from the surface. Another 120 kg of weathered and fragmented kimberlite were collected from Pipes 3, 4 and 5.

Lakefield Research conducted diamond extraction on the samples, which yielded a total of 681 diamonds and 62 macrodiamonds (exceeding 0.5 mm in at least one dimension). Of the macros, 29 measured more than 1 mm along the largest dimension. The biggest diamond came from Pipe 2 and weighed in at 0.77 carat.

Pipe 1 yielded 37 macros and 359 micros. Pipe 2 returned 16 macros and 143 micros. Pipes 3, 4 and 5 returned 9 macros and 117 micros. Most of the stones are classified as gem quality and are white and transparent. Fifteen are transparent, with colours ranging from pink to amber.
