Ashton Mining (ACA-T) has identified four more kimberlite pipes on its Buffalo Hills property in north-central Alberta.
Recent reverse-circulation drilling of aeromagnetic anomalies 30 km to the east and southeast of kimberlite K-14 have discovered four new kimberlite pipes, dubbed K-10, K-32, K-92 and K-93. This brings the winter exploration total to six new kimberlites. In late February, two other pipes, K-11 and K-15, had been found in the vicinity.
The overall number of kimberlites discovered on the Buffalo Hills project now totals 20.
The anomalies that coincide with the newly identified pipes range in size from 100-by-150 metres to 600-by-200 metres, and are covered with 13 to 127 metres of overburden.
In related news, results from dense-media-separation analyses of the K-5 kimberlite returned no diamonds. The sample weighed 3.55 tonnes and was taken from six core drill holes.
Analysis of a 4-tonne sample from a pit on K-5 recovered 0.03 carat of diamonds with a maximum dimension greater than 0.8 mm. The three largest stones had a maximum dimension of 1.67, 1.24 and 1.2 mm, respectively.
Ashton believes that because of its large size, the K-5 kimberlite has potential for higher diamond counts.
Reverse-circulation drilling on K-14 has been delayed because of operational problems. Large-diameter core holes on the K-91 kimberlite are being drilled in an effort to collect a mini-bulk sample of about 40 tonnes.
Ashton is the operator of the Buffalo Hills project and holds a 42.5% share of 2.3 million ha in
the Buffalo Hills region. Alberta Energy (AEC-T) holds another 42.5%, and the remaining 15% interest is held by Pure Gold Minerals (PUG-T).
The partners also share ownership of an additional 9.1-million-ha land package in the vicinity of Buffalo Hills. There, Pure Gold holds 49% and Ashton and Alberta Energy hold 25.5% each.
