Hi Alan;
I would like to bring to the attention of followers on your thread, a recent news release by Copperhill Corp. of a discovery of the first kimberlites in Northern Labrador.With the recent discoveries of diamonds by Twin Gold just across the border in Quebec,it looks like we may have a whole new "diamond province" in the making.It would appear that Twin Gold and Copperhill may well attract the international attention of investors in the months ahead.
Here is the Press Release:

Copper Hill Corporation ("Copper Hill"): First Kimberlite
Dykes Positively Identified In Northern Labrador.
ST. JOHN'S, NEWFOUNDLAND--Copper Hill is pleased to announce the
discovery of kimberlites on its claims in Northern
Labrador-Nunavut. In September 1998, Copper Hill geologists
sampled six of eight known dykes previously mapped by government
geologists as ultramafic lamprophyres. Petrography and mineralogy
both confirmed the presence of diamond indicator minerals within
at least two separate kimberlite dykes. These results are
significant, since they are the first kimberlite dykes discovered
in Northern Labrador.
Copper Hill is extremely encouraged by these findings and note
that they are located in the same vicinity as the significantly
diamondiferous kimberlite dykes very recently reported by Twin
Gold Corporation just across the provincial border in Northern
Quebec.
In May 1999 the samples, including bedrock, stream sediments and
one soil were split and sent to Kennecott Canada Exploration Inc.
(Kennecott) laboratory in Thunder Bay, Ontario. A discription of
the mineralogical and chemical particulars are deferred to the
underlying footnote.
Based on the petrology to date, at least two of the six dykes
sampled are kimberlites, and the remainder were classified as
lamprophyres, though they have some mineralogical features in
common with the kimberlites. Significantly, Kennecott's in-house
discriminatory curves for pyroxene separates show that the
geotherm for the dykes is permissive for diamond preservation.
Copper Hill which trades on the CDN holds a number of mineral
exploration projects in Newfoundland and Labrador. For further
information, please call 709-739-4780; fax: 709-739-4785, or visit

location maps and other data.
On behalf of the Board of Directors,
Earl R. Benson, President.
Footnote: Sampling and mineralogical/chemical particulars:
The initial sampling conducted by Copper Hill was of a
reconnaissance nature, designed to determine whether the dykes
were kimberlitic and not to test their diamond potential at that
stage. The rock samples were less than 20 kg and collected from
single sites within a dyke, and the stream and soil samples were
less than 5 kg. The stream sediment samples are still being
analyzed.
All the samples were processed at Kennecott for greater than
0.25mm diamond indicator minerals and the rock samples also
underwent petrological examination. The heavy mineral concentrates
from these two dykes confirmed that they also contained diamond
indicator minerals. These minerals included fosteritic olivine, G9
lherzolite garnet, eclogitic garnet, megacrystic garnet,
clinopyroxene, orthopyroxene, ilmenite and chromite, a classic
kimberlite suite.
The diamond indicator minerals were sent to R.L. Barnett
Geological Consultants of London, ON for analysis by electron
microprobe, which confirmed the presence of the above material.
Kennecott also reported the clinopyroxene and orthopyroxene
chemistry, based on an in-house geothermobarometer plot within the
temperature and pressure field of diamond. Also, Kennecott reports
that the soil geochemical sample collected over one dyke yielded
significant pyrope, chrome diopside and olivine.
Kennecott recommended that Copper Hill collect more sample for
caustic fusion to check for the presence of diamonds. Copper Hill
plans an aggressive exploration and sampling program during which
samples with a minimum of 150 kg will be collected from each site
and detailed down-ice stream, soil and till sampling will be
completed.
