Mr John Auston reports
The first analytical results from the Buffalo Hills kimberlites to date
indicate generally favourable mantle chemistry for diamonds and preliminary
results of caustic dissolution analyses show that one of the three pipes
tested so far has a significant content of micro-diamonds and
macro-diamonds.
Geochemical analyses of indicator minerals in kimberlite from pipes K2, K4
and K14 have confirmed the presence of G10 pyrope garnets and abundant
chromites whose chromium and aluminum chemistry plots in the diamond
inclusion field. These data confirm broadly favourable conditions for the
presence of diamonds.
The first micro-diamond analyses of kimberlites K2, K4 and K14 have
recently been received from the company's laboratory in Perth, Australia.
Results confirm that each of these pipes is diamondiferous. Kimberlites K2
and K4 returned low diamond counts while kimberlite K14 returned
significant numbers of both micro-diamonds and macro-diamonds. The results
from K14 have been confirmed by analysis at the company's own laboratories
in North Vancouver, using the recently expanded micro-diamond processing
facility. Detailed below are the results of the diamond analysis:

x Macro-diamonds are individual grains with one dimension equal to or
greater than 0.5 mm.
xx Analysed in the company's North Vancouver laboratory; all others
analysed in the company's Perth laboratory.
Micro-diamond analyses alone do not provide sufficient information to
assess the commercial diamond potential. The results from these initial
small samples are encouraging, however, and indicate that additional
testing of these pipes, including mini-bulk testing, is warranted.
Results of the laboratory analyses of the remaining eight kimberlite pipes
will be provided as they become available over the coming weeks.
Ashton Mining and Pure Gold Resources have an option agreement with Alberta
Energy Company whereby Pure Gold and Ashton have the right to earn
interests of 15% and 42.5% respectively in the Buffalo Hills property.
Total landholdings, including option and joint venture lands, comprise 26.8
