Twin Mining (TWG-T) has okayed a $1.7-million first phase of exploration for its Jackson Inlet diamond property in Nunavut.
The program will include ground magnetometer surveying, soil sampling, gravity and core drilling on 12 anomalies identified by a previous 6,641-line-km airborne magnetometer survey.
Twin also plans further work on the Freightrain pipe where Twin previously collected a total of 228.19 tonnes of blasted kimberlite from six sample sites. A total of 869 diamonds weighing 46.21 carats were recovered by Lakefield Research, using a 0.8-mm lower-size cutoff. The six sample sites produced variable grades, ranging from 0.106 to 0.336 carat per tonne, for an average of 0.202 carat per tonne.
The largest recovered stone is gem-quality and 1.56 carats, measuring 7.1 by 6.27 by 3.94 mm. The next four biggest stones weigh 0.936, 0.87, 0.867 and 0.809 carat.
Last year, Twin drilled a series of 17 short holes into Freightrain but was unable to penetrate to depth to any degree. Fifteen of the holes intersected a total of just 314 metres of kimberlite, with 14 of the holes ending in limestone.
In all, Twin has budgeted $10 million for exploration on the Jackson Inlet property.
