Diamonds
Considerable experience has been gained by Mackay
& Schnellmann Pty Limited in the exploration of primary and
alluvial diamond deposits. In addition some assignments have been
undertaken on other gemstones.
Examples of recent assignments on diamonds are:
SOUTH AFRICA, 2001
A multi-client study is under preparation for a large area of South
Africa prospective for alluvial and hard rock diamond deposits.
Remote sensing and historical data are being incorporated in a digital
database and a regional prospectivity analysis is being carried
out over the area to define targets for follow up exploration.

currently underway.
LIBERIA, 1997
A field investigation was conducted over mineral concessions covering
the currently productive alluvial diamond areas along the Lofa and
Yambesei Rivers, the kimberlite prospective Wolegizi Ranges area
of central and northern Liberia and coastal diamond concessions
in the Robertsport and Lake Piso areas. Investigations focussed
on target confirmation and generation based on geomorphological
interpretation of the areas using digital Landsat TM and GIS software.
Recommendations included costed future exploration and evaluation
programmes. The assignment was carried out on behalf of an overseas
explorer.
WESTERN AUSTRALIA, 1995
As input to a Fair and Reasonable report on a related party transaction
whereby Australian Gold Fields N.L. were acquiring certain tenements
from Jade Creek Resources NL, a Specialist Geologist's Valuation
was prepared on the diamond mineral property interests of both parties.
KAZAKHSTAN, 1994
Evaluation of diamond exploration data was carried out on behalf
of an overseas client together with prospect evaluation of several
sites and recommendations for future exploration. Work had been
undertaken by Kazakhstan governmental agencies over a number of
years. Exploration techniques employed had included drainage sampling,
diamond core drilling, large diameter augering and so forth. Diamonds
were present in kimberlite pipes and in the eluvial and alluvial
deposits that were present in the vicinity.
RUSSIAN FEDERATION, 1994
A diamond project area in Primorski Kray, Far Eastern Russia was
examined on behalf of an Australian exploration company. Geological,
drilling, geophysical and bulk sampling data were assessed during
a site visit, independent sampling and sample processing were conducted
and a report was prepared on the status and prospectivity of the
area.
Additional examples of assignments involving
diamonds will be found on the Expertise
pages of this website.
