GIA FE09 (GIA Laboratory Bangkok Field Expedition 09): Part 02: Sep. 02 - Sep. 20, 2009: Mozambique:
This is the second part of the GIA Field Expedition to East Africa, I'm leading for the GIA Laboratory Bangkok: I arrived in Nampula, Mozambique from Dar Es Salaam with gemologists Lou Pierre Bryl (Canada), Stephane Jacquat (Switzerland) and Jean Baptiste Senoble (France) on Sep. 20th 2009. We were welcome at the airport by Moussa Konate of "Mozambique Gems Ltd". Moussa Konate is one of the partners in the "paraiba like" tourmaline mining operation in Mavuco.
Our objectives were to visit the tourmaline deposit near Mavuco village (A deposit which was visited in the past by my colleague at GIA Brendan Laurs who helped me to prepare this expedition) and the different ruby deposits in Niassa and Cabo Delgado areas in Northern Mozambique in order to complete the work we already done at GIA Laboratory about rubies and tourmalines from Mozambique:
About Tourmaline from Mozambique, I would like then to invite to to read the article in Gems & Gemology (Spring 2008): Copper bearing (Paraiba type) tourmalines from Mozambique by B. Laurs et al.
About rubies from Mozambique, I invite you to read the following:
See Rubies from Northern Mozambique on www.giathai.net, it is a big pdf on which we communicate our results after studies rubies reportedly from Mozambique we studied at the GIA Laboratory Thailand beginning 2009.
and also GIA Insider: (Sept 18th 2009) From Gems & Gemology (Gem News International) : New rubies from Mozambique by S.F. McLure and J.I. Koivula, an interesting publication about the rubies reportedly from Montepuez, which were studied in the USA recently.
- "Pareciba Paraiba", meaning "Paraiba like", tourmalines from Mavuco, Mozambique: Visiting the Mozambique gems mining operation at Mavuco was easy as Moussa Konate and his Brazilian partner Keke Saint-Clair Fonceca were present. We visited the area twice, a first time with Mozambique gems geologist: Enrique Shirinza, a second time with Moussa Konate and Keke Saint-Clair Fonceca. We could witness the mining and washing process. An update about copper bearing tourmaline mining in Mozambique will be soon published by GIA with the information collected during our visit.
