Mr John Auston reports
Ashton Mining has received the first diamond results from mini-bulk sampling of
kimberlite K14 in the Buffalo Hills project, northern Alberta.
The samples, totalling 27.42 tonnes in weight, are from reverse circulation drill
holes (8.17 tonnes) and surface pits (19.25 tonnes). The seven vertical holes were
drilled at 25 metre centres along an east-west line 150 metres in length in the
south-central portion of the main K14 magnetic anomaly. The five surface pits are
spaced irregularly along an east-west distance of 50 metres on the northern part of
the main anomaly K14, 75 metres north of the drill holes. The results of the dense
media separation tests are tabulated below.

All results indicate a high variability in diamond content over relatively short
distances. Generally the diamond contents of the pits are lower than those of the
drill holes. The drill hole samples collected over 150 metres horizontally and up to
90 metres vertically are more representative of K14 than are the pit samples
which were collected from surface. The drill hole data should be considered a
more reliable indication of the commercial potential of the K14 kimberlite.
The five largest stones recovered weigh 0.60, 0.30, 0.28, 0.21 and 0.18 carats.
Many of the diamonds are colourless, and there are some coloured stones as well.
The sample size is too small however, to make any definitive comment on quality.
There is some evidence of breakage of stones resulting from the drilling process,
although the larger stones noted are whole.
The results are an encouraging indication that kimberlite K14 contains a
population of diamonds of commercial size. Considerably larger samples are
required to accurately determine the grade and quality of the diamonds and hence
the commercial potential of the deposit.
Hope K91 has bigger stones, it would wake up the folks on the sidelines. |
