The Sheahan Diamond Literature Reference Compilation is compiled by Patricia Sheahan who publishes on a monthly basis a list of new scientific articles related to diamonds as well as media coverage and corporate announcements called the Sheahan Diamond Literature Service that is distributed as a free pdf to a list of followers. Pat has kindly agreed to allow her work to be made available as an online digital resource at Kaiser Research Online so that a broader community interested in diamonds and related geology can benefit. The SDLRC Blog is a guest commentary by an industry expert about articles, themes and trends in recent issues of the SDLRC.

Brooke Clements received a B.Sc in Geology from Indiana University and an M.Sc in Economic Geology from the University of Arizona. From 1982 to 1997, he was an Exploration Geologist and Regional Manager for Exmin Corporation where he conducted diamond exploration programs throughout the United States. From 1998 to 2007 he was Vice President, Exploration for Ashton Mining of Canada Inc. Under his leadership, the Ashton-SOQUEM exploration team discovered the Renard diamond district in Quebec where Stornoway Diamonds opened the Renard Diamond Mine in 2016. From 2007 to 2015 he was President of Peregrine Diamonds Ltd. where he led the team that discovered the Chidliak diamond district on Baffin Island in the Canadian Arctic. Currently, Brooke is President of JBC Ventures Ltd., a consulting company specializing in mineral exploration and community and government relations. He is also President and CEO of Craton Minerals Ltd., a private diamond exploration company focused on discovering North America's next new diamond district.
Brooke Clements has volunteered to highlight the scientific articles that caught his attention in the monthly reference compilations. The opinions expressed are solely his and he can be reached at .
SAIMM Diamond Conference: The highlight this month is a conference held in June by the South African Institute of Mining and Metallurgy (SAIMM) in South Africa. There were presentations by experts on timely topics including: diamond liberation in processing plants including XRT and grease, diamond project financing, alluvial deposit exploration with geophysics, individual diamond analysis, transport of KIMs by termites, diamond fingerprinting, the discovery of Jwaneng and a number of papers on mining operational issues. Papers submitted by the authors should provide good summaries of the talks. SAIMM normally provides conference proceedings for free on their SAIMM website. The proceedings have yet to be posted, keep checking, I expect they will be a valuable reference.
I think all papers on lamproites and exploration for lamproite deserve special attention and a little reflection from diamond explorers. Is it possible that Australia and Bunder in India are the only places in the world with economic lamproites or do we not pay attention to signs they might be there and/or are they just harder to explore for than kimberlites? Time will tell.
A gem from 2015 unearthed by Pat that describes the history of diamonds in Zimbabwe. This is an update to a 1981 paper and the author emphasizes how difficult it is to get accurate production and exploration data. It is estimated that 140-200 kimberlites have been discovered to date in the country. Reported diamond production until 2006 was modest, dominated by one alluvial deposit, River Ranch and Murowe. That changed in 2006 with the famous Marange diamond rush.
